About Mums, and a little about Dads too.

I wrote about cuteness a couple of posts ago, and this started me thinking about mothers, both human and animals and how the bonds that they form with their offspring.

Many animals do not look after their offspring, just casting their fertilised eggs into the seas like many fish or placing their eggs on a food plant as butterflies and moths mostly do. However, many animals do look after their eggs and young offspring, often for extended periods of time.

It is common for the mother of an animal to look after it rather than the father, but it is not uncommon for the father to look after the offspring, and more commonly both parents will look after their progeny.

For example, the egg laid by most species of Kiwi is incubated by the male member of a pair of birds. Also, in the Seahorse, the female deposits her eggs inside the male’s “brood pouch” and the young of the Seahorse develop there.

Once young animals are born, often the female parent will take care of them for some time after they are born, but this is not a definite rule. Sometimes the male parent is around and provides some support and protection, and even if the male parent is around, he may remain fairly distant, with the female doing most of the caring for the young animals.

A common sight is a mother hen closely followed by her chicks, with the aloof cockerel strutting around the farmyard. In a pride of lions, the nucleus of the pride consists of the females and offspring while the associated males remain close.

In humans, the so called “nuclear family” is common, at least in Western cultures. A nuclear family usually consists of a couple and their children living in a single house, and is a relatively recent phenomenon, with extended families being common in many cultures, including Western cultures, until fairly recently.

In such a nuclear family, the father goes out to earn money for the family every day, leaving the children in the care of the mother for the day. Such role separation and assignment could be seen as “natural” and “obvious”. This can be problematic when the couple are not male and female, when role assignment is trickier.

It is likely that there is an instinctive drive for a mother to care for her children and for the father to be assigned the role of provider for the family. Certainly this tendency for children to be cared for by the mother and for the father to fill another role can be seen in most societies, even those without the concept of the nuclear family.

In a family consisting of a couple of same sex parents, this role division is not well defined and indeed such couples may decide to share both provider and carer roles within the family group, which could speculatively lead to kids who are unclear about the distinction between the carer and provider roles.

Kids are resilient though, and being more willing to share the roles when they grow up and form their own, probably heterosexual, relationships and families may even be an advantage. That’s not to say that the father in a heterosexual couple whose parents are also a heterosexual couple are not capable of caring! The roles in Western societies are not so strictly defined that a father cannot be a carer for some of the time, and that a mother cannot be a provider.

Regardless of such quibbles, mothers tend to be more caring and nurturing than fathers in Western societies. Both boys and girls tend to go first to Mum when a knee is scraped or an elbow bashed, and they go to Dad for the resolution of disputes, such as when a sibling has stolen a favourite toy and won’t return it.

This is probably because the mother has more invested in the children than the father. She has carried the child for nine months, culminating in a painful delivery, while the father has watched on and the only pain that he has suffered was when his spouse squeezed his hand too hard during a contraction and left nail marks in it. Of course, I am drastically under valuing the support that the mother has received from her spouse.

Mother have a close bond with their children, and we can see it in modern society, where a couple is not always “till death do us part”. When a couple splits the children more often seem to go with the mother, although there are blended families where some of the kids are the father’s and some are the mother’s.

Mothers can be particularly close to their daughters, but they are even close to their sons. No other person has changed your nappy (diaper), clothed you, nursed you through minor ailments, and fed you from the moment of birth until you leave home. Step daughters and sons can sometimes have difficulty getting as close to step mothers, and this can cause issues.

Poor old Dad. He gets the affection, the love, but usually not to the same depth as the children love their mother. Actually, I think that the bonds that form between a man and his kids are just as deep as mother love, but they are manifested in different ways. Dad is the one that the kids look to for protection much of the time, Dads tend to be the ones who encourage the kids to stand on their own feet.

The difference is that Dads are in general more able to form relationships at a distance. He may mainly see his kids in the evenings and at weekend. Modern life has pretty much forced a hands off approach to parenting for Dads. When a split up comes it is frequently easier for a father to move away from his children, painful though it may be than for a mother to move away from them.

Breaking up a family is always difficult, but with nuclear families it is more difficult. In an extended family there are always granddads. grandmas, cousins and aunties and uncles to take up the slack. The modern child doesn’t have quite so much support. It’s a wonder that, in general, they still turn out OK.

Time and time again

English: Albert Einstein Français : Portrait d...

It is often said that Einstein considered time to be an illusion, and web sites which collect notable quotes often just claim that Einstein said “Time is an illusion“. This a classic case of taking a quote and posting it out of context. What Einstein actually said was more complex and more subtle.

He actually said:

The distinction between the past, present and future is only a stubbornly persistent illusion.

He did not claim that time is an illusion, but that the moment of “now” is an illusion. In fact his equations give time the same status as space. For instance, the square of the space time interval between two events is defined by combining the square of the space interval minus the square of the time interval interval. (Provided all values are expressed in the same units.)

The details don’t matter too much here. The point is that time is treated equally with the space dimensions, and no one is claiming that Einstein was arguing that space does not exist. There are many references to be found on the Internet which explain Einstein’s ideas with variable clarity and accuracy.

I said above that Einstein argued that the instance of “now” is an illusion, but I was over simplifying. What I believe that he was saying was that while we experience a “now” now, we also experienced a “now” ten seconds ago, and one second ago, and one instant ago. There is nothing special about the “now” moment and all instants of time are “now” moments.

This isn’t that surprising really. If you consider where you are at a particular place and at a particular time, not only is there a “now” moment, there is also a “here” place. When you move to another place, you have another “now” moment, and another “here” place. To experience an event you have to have both.

If we are taking a road trip we have no difficulty with the concept that the “here” place changes continually and that a place we have passed through was a “here” place when we passed through it, and that a place further on will later be a “here” place. Where ever we are we are “here”.


http://www.gettyimages.com/detail/500202414

You might argue that time is fundamentally different from space, in that we can see what is in front of us in space but we can’t see what is in front of us in time. This is true, but maybe we just don’t have the physical equipment to do so. We can use sight to look around as see what is not “here”, to some extent, but we don’t have complete visibility to things around us.

If we did we would not bump into things and fall off of things as much as we do. We use sight to build a picture of things around us, but we don’t have physical access to those things until we move up to them.

Since we don’t have “time vision” we have use whatever abilities we can to work out what is in the future, such as reason and intuition, both of which have limited success. We do have some ability to fairly accurately guess the future, as evidenced by our abilities to catch a ball thrown to us. If you have ever watched a top table-tennis match, you will no doubt be amazed at how accurately we can so this, as the ball whizzes from end to end of the table.

Time is measured in seconds and space is measured in metres (or hours and yards or other equivalent units). This seems to be a difference between the space dimensions and the time dimension.

Time dilation spacetime diagram05

However it is easy to show that there is little fundamental difference. Distances are often measured in terms of time – astronomers refer to a light year, which is the distance that light travels in one year. It is not often, however, that the opposite is true. Times could be measured in terms of light metres, or the time it takes light to move a given number of metres, but this is not usual, possibly because a light metre is such a very short period of time.

Interestingly some people claim to be able to “see” the future. They are claiming that they have a sense similar to vision which they use to determine what is going to happen in the future. While it is possibly conceivable to have such a sense, there appear to be no organs in the body which could be used to “view” the future.

Panoramic view of the future Phoenix-Lake from...

Such organs would have to have receptors which would have to receive information about the future just as the eyes receive information about things that are relatively distant, and that information would have to travel in time from the future to reach the receptors in the present. This appears to be counter to all known physics. Possibly “unknown physics” would allow this, but I suspect not.

In any case the human body doesn’t appear to have any receptors which could possibly serve this purpose, and although not everything is known about the human body, such organs, if such existed and could be used by some people, would be probably be apparent.

English: "Sight" - First of a series...
English: “Sight” – First of a series of 5 engravings illustrating the five senses (Photo credit: Wikipedia)

What about the brain? Could the brain perhaps receive information about future events in some way? Well, the brain is an organ for processing information, not for receiving information from the future.  There is nothing like a receptor in the brain, though it is connected via nerves to receptors which terminate those nerves and when stimulated excite the nerves which then pass the stimulation to the brain.

In my opinion, which of course could be wrong, there is no way that information from the future could be detected by the human body, and in particular by the brain acting as a receptor. That does not mean that time is in any way different from space as a dimension. What it does mean is that we are able to perceive the dimensions of space differently from the dimension of time.

That doesn’t address the question as to why the space dimensions are accessible to vision and time is not. It only addresses the question of why we can “see” the space dimension, but cannot “see” the time dimension. Something links the space dimensions into one seeming whole, while the time dimension seem singularly different.

Cuteness

Cute Baby
Cute Baby (Photo credit: Wikipedia)

If you saw a human being whose body was only three times the size of his/her head instead of the usual six times, who lacked the ability control his/her limbs and bodily functions, who was almost unable to communicate and who needed round the clock care, would you conclude that they were unfortunately seriously physically disabled, or would you lean in and say “What a cute baby!”

When the characteristics of a baby are listed like that, it makes it seem very unattractive, but, unless the baby is playing up in some way, most, but not all people, would find it appealing. There is something in our natures that is attracted to babies and young children.


Embed from Getty Images

It’s not just the young of our own species that we find attractive. A small bumbling puppy or kitten very often causes us to go “Awww!”. We often have an urge to cherish baby animals, and this urge appears to extend to other species to some extent. It is not infrequent that a mother of one species will care for the young of another species, even species that would normally be prey for the mother.

That’s quite astounding when you think about it – the mothering instinct has completely suppressed the predatory instinct. Of course, if food were scarce, possibly the mothering instinct would not be as strong as the predatory instinct.


Embed from Getty Images

Obviously the pleasure that people get from babies (and pets) outweighs all the negative aspects of looking after them. Babies can be demanding, annoying, frustrating and downright unpleasant to live with, if the truth be told. And they are expensive to look after!

Other people’s children will sometimes cause you to wonder why the parents didn’t practise birth control, and your own will frequently be an embarrassment to you, but overall society tolerates the anti-social behaviour of children to an amazing extent. Of course, parents tend not to take babies and small children to events where they would cause chaos and mayhem, such as a musical concert or a play.

We could term this attractiveness of young children to adults “cuteness”. “Cuteness” invokes the parental instincts that can in some circumstances overcome the instinct of self preservation. In having produced offspring, a parent has performed almost all that is necessary for the propagation of the species, and the only task left is for the parent to ensure that the child gets the best start in life that is possible.

The cuteness of children allows such human institutions as fostering. A child can be looked after by a non-relative, if the parent (and all the child’s relatives) are unable to bring up the child for any reason. Sometimes, maybe often, a fostered child comes with “problems”. They may have been mistreated, for example, and have become reserved or disruptive.


Embed from Getty Images

Foster parents are often special people, who take in unwanted children and do their best to sort out any problems and issues that they have, trying their hardest to break through any barriers that the child may have put up, earning the child’s trust if possible, and even their love.

That is important, because the parent/child bond is bidirectional. The parent loves the child, and the child loves the parent back. I suspect that the parent loves the child first and the child learns from this to love the parent back. When a child is born, it is barely aware of its surroundings and parents grow to love their child even before the child learns to and is capable of responding to the parents.

It’s a tragedy that so many parents either don’t know how to love their children, or their love fades quickly over time. I guess it is not surprising that in a few cases parents don’t know how to love their kids, and I also guess that this can be the result of the parents’ parents not showing their kids much love.

However,  that is pure speculation. It’s reasonable, I’d say, but not definite, so far as I am aware. Certainly, children who come from environments where the mutual affection in a family is apparent will most likely prove to be loving parents themselves.

English: Russian Family

It is hard to watch when a child goes wrong, or is caused distress by something external. Older children of even loving parents sometimes go “off the rails”. They may indulge in drugs, or alcohol, or indiscriminate sex, or may develop mental or physical illnesses. They may simply develop world views that are opposed to those of their parents. They may even vote for the wrong political party!

This wayward behaviour is often worst for parents who have rigid world views, such as those who are religious or are philosophically rigid. It may indeed be this very rigidity of viewpoint that has pushed their kids away. Most parents encourage their children to develop their own personalities, but sometimes these personalities clash with those of the parents.

The innate tendency to find children and the young of pet animals cute serves as the glue to bind the parents to a very demanding entity in the child. The cuteness of a child is only partially visible to others though, and there may be conflict between parents and other adults in places like restaurants and planes and busses.

As children get older the cuteness factor tends to wear off. By the time that they leave the family home the bonds between parents and children have transitioned between child/parent and young adult/parent. Though the bonds are still there they are qualitatively different to the original bonds formed just after the birth.

Sometimes the cuteness idiom is probably taken too far, as in the Japanese quality of Kawaii. In Japan many older children and young adults dress and behave in ways which in younger children would be considered cute. In my opinion this is decidedly dubious, as the Kawaii quality is too easily linked with sexual attractiveness, and making oneself more attractive by acting younger than one’s age can possibly cause younger children seem sexually attractive.

In contrast, in Western cultures children will try to dress and act older than their age when they begin to feel that they need to be attractive to others. While this is not ideal, it does mean that sexual attractiveness is directed to older looking partners, and not, as in Japan, to younger looking ones.

Who’s a good boy, then?

We love our pets and they, so far as they are capable, love us back. In particular dogs reciprocate when we shower our affection on them. They are so grateful to us, and more than repay us for adopting them and looking after them, providing them with food, housing and the aforementioned affection.

Cats on the other hand, do not appear to be so grateful for us letting them into our lives, and some cats seem to have an air of disdain for anything human related. I’m told by cat lovers that they are as affectionate as dogs, but it all seems to be very much on their terms.

Maybe that’s the way it should be. But maybe it is sheer hubris to assume that we are the top mammals, and that we should be treated as such. Cats are perhaps showing us that there are other ways to be superior.

There are other pets of course, such as birds and budgerigars, fish, rabbits and small rodents such as guinea pigs and hamsters, not to mention mice and rats. Some people have even more exotic pets, such as lizards and snakes, and even spiders.

While one can’t have as close relationship with these creatures as with dogs or cats, owners claim that these animals do show affection for their owners often in subtle ways. I’m sceptical that fish, snakes and spiders do so, but I’m willing to concede that the rodents probably do show affection to some small extents.

It’s probably that people began keeping pets as a convenient food supply. In some places rodents such as guinea pigs are bred for food, and the rabbits which have become pests in some parts of the world were definitely introduced as a food source. Apparently rabbits were introduced into the UK by the Romans as a food source, and it’s hard to realise that rabbits haven’t always been in the UK these days.

Larger animals, such as pigs, sheep and goats and other animals that are kept for their meat sometimes end up as pets. Maybe the child of a farmer may have hand-reared the animal when something happened to the animal’s mother and become attached to it. This is often seen as a waste by the farmer, but he may indulge the child and allow the animal to live.

In most cases of such larger pet animals, the animal does not live with the owners, but merely gets special treatment from the owners. It is a sort of half and half pet animal. In rare cases the pig or other animal may actually live with the humans, but this is considered eccentric. Often media will use such cases for “human interest” stories. I often wonder if the pig on the couch is really happy with the situation or whether it would prefer to be grubbing around outside.

Some people keep horses. While horses are usually considered pets, but are working animals, some people get very close to their horses. It more of a close companionship than a really human and pet relationship, but horses do in many cases reciprocate when the humans show affection.

Showing affection implies some sort of consciousness behind the pet’s eyes. Some people argue that while animals do respond to human affection that their response is merely a stimulus/response reaction of the pet to the environment, which of course includes the human being. While pet seems to recognise that the human is being affectionate, the pet is a philosophical zombie, and there is nothing else going on.

I find this argument to be dubious. We after all are conscious beings, and this consciousness must have evolved in our ancestors from scratch. I don’t just mean our human ancestors, but the ancestors of us, apes, cat and dogs, pigs, and horses. In other words all mammals, and maybe even the ancestors of other types of animal. I’d like to think, for example, that Tyrannosaurus Rex had some dim idea of itself and its place in the world.

This is, of course, the view that animal rights’ activists and vegetarians and vegans have of animals as sentient beings. While I have certain sympathies for their points of view, I feel that humans have the right to eat meat as part of their diet, just as any carnivore like a lion or a tiger has the right to hunt, kill and eat other animals.

Male Lion (Panthera leo) and Cub eating a Cape...

We are have evolved from hunter-gatherers whose diet included meat from animals that we hunted and killed and our bodies have developed (maybe even evolved) to subsist on such a diet, and we have issues if we try to exclude meat from our diets. Vegetarian diets tend to favour beans and other plant proteins which our bodies are not adapted to digest and plants do not contain much of some nutrients which our bodies need.

Pets are probably kept more for companionship than anything else. The mutual affection between a pet and its owner probably arises from that. Some people (as in any group of humans) tend to go to an extreme, as epitomised by the familiar “cat woman”. Such people often have psychological problems and tend to be somewhat withdrawn from society, and may form an extreme connection with their cats, and have a disregard of their own well-being.

I prefer dogs over cats, because dogs interact with humans in a more human way than cats do, and kids who grow up with dogs will have seen all the training and looking after that their pets need, and themselves learn about responsibility. A pet dog is totally dependant on a human for housing, feeding and exercise. If the dog becomes ill, they learn that the owner is responsible for seeing that the illness is treated, and when the dog dies, they learn how to cope with death and grief.

When the human race expands to the stars, if we ever do, we will almost certainly take our pets with us. The dog, the cat, the guinea pig and the budgerigar will travel to the stars with us. They may be riding on our coat tails, but that is a measure of the success of their species and their connection to the human race.

Loneliness

Robinson Crusoe was marooned for years on a tropical island. At first he succumbs to despair, but later he starts to make things easier for himself, at first rescuing goods from the shipwreck which is fortunately accessible at least for a while on a reef.

He has no one to talk to, until Friday, but he is kept busy just surviving. This business, wondering where the next meal was coming from, how to provide himself with shelter, all the minutiae of just living would have initially staved off all sense of loneliness.

Later on though, when his immediate needs were catered for, he must have reflected on the fact that he was totally alone on the island. (I read the book years ago, and I’m speculating – I can’t recall if he ever got into a philosophical mood or not). It would have been a driver to explore the island and finding no other people would have been a blow.

People in general need other people. In the book Treasure Island by Robert Louis Stevenson, Ben Gunn is marooned on an island for years and become slightly unhinged by the loneliness. He spent a lot of the time on the island dreaming of one thing – cheese. However, he does not completely lose his senses and is able to take part in the events that follow.

Some people choose to isolate themselves from the rest of the human race, mainly, it seems for religious reasons. It is possible for such hermits to voluntarily return to the human race, something which is not possible for those who are marooned on an island, and this may make the separation more bearable.

The reason that hermits choose to isolate themselves from the human race is so that they can concentrate or religious or spiritual matters without being distracted by the minutiae of human life. Obviously they still need to eat and perform bodily functions, but those can be kept to a minimum and the hermits mind can be free to concentrate on one thing for much of their waking moments.

While human companionship can help to keep one sane, the constant interruptions to one’s train of thought can be distracting or irritating. Samuel Taylor Coleridge was writing the poem “Kubla Khan” when he was distracted by a person from Porlock and the poem was not completed as originally Coleridge envisaged.

Computer programmers often find that when they are concentrating on their task they will “enter the zone or the flow“. This is an almost trance-like state where the programmer is totally immersed in the task at hand, and the interruptions of normal life are not welcomed. A programmer in the zone may regard time spent on sleep, food and other necessities as unimportant, and this is why programmers sometimes subsist on coffee or energy drinks, and eat pizza and other fast foods that can be ordered in.


http://www.gettyimages.com/detail/474217642

The immersive effects of the zone are not only felt in programming, I believe. Programming is in many ways an art, and I can imagine that the same is true of the other arts, such as painting and writing, as the example of Coleridge suggests, though he was using opium at the time he was writing Kubla Khan.

The feeling of being in the zone is, for the most part, intensely solo. While two or more programmers can work simultaneously of the same piece of code, this is much more difficult to achieve. I’ve seen programmers team up and program, but the feeling of being in the zone is much more fragile when more than one person is involved.

English: Programmer

In contrast, debugging a malfunctioning piece of code can be easier for two or more, as the different insights broaden and direct the flow into areas that neither would have thought of by themselves but in general the immersion is not so deep.

Quite often an isolated person, say a shipwrecked person, or an elderly or sick person who is not mobile and therefore spends a lot of time alone, will have an animal as a companion. The little old lady has one or more cats. The shipwrecked or marooned person may have a dog. A companion animal eases the separation from the human race.

A lonely person may pick an unusual animal as a companion. Some sources suggest that Michael Jackson made a pet of a rat and that his father killed it, but this story is muddled with the story behind his hit song “Ben”.

An isolated person may talk to the animal in default of being able to talk to other human, and may unwisely attribute human traits to the animal. If the person is alone with the animal for too long he or she may come to believe that the animal responds either verbally or by actions.

Sometimes an isolated person may imagine a fictitious companion, either totally invented or based on a real person. He or she may act out what he believes that the imaginary person would act out. In the film “Psycho” Norman Bates assumes and acts out the identity of his dead mother, who he killed 10 years earlier. Bates was isolated by his mental illness, and not by being physically isolated.

There are various causes of isolation – it may be unintentional, as in a shipwreck, or it may be intentional as when a sailor is marooned for mutiny, or a person may be isolated as a result of sickness, either mental or physical, or it may be a side-effect of old age. A person may be isolated by deafness or blindness, or physical inability to move.

However, some people seek isolation in the form of “peace and quiet”. If a person is highly stressed in their day-to-day life, they may find themselves looking forward to immersing themselves in a book, or taking a bath, or in any of hundreds of ways of isolating themselves from the general hubbub of human society. Possibly with a reasonable supply of alcohol to hand, merely to aid the relaxation of course.

Voters and non-voters

Hillary Clinton won more votes than Donald Trump in the US elections, yet she didn’t win the presidency. This has led to many of Clinton’s supporters to cry foul, and talk about getting rid of the electoral college system that they have in the US.

It’s not going to happen. The electoral college is a result of the unique formation of the United States of America. Before the Union all the states were autonomous and had their own laws and regulations and these were protected in the US Constitution. One of the safeguards which was built in was to protect the electoral system within a state from being replaced or modified by those not from that state, and this resulted more or less directly in the electoral college system.

English: 1908 Electoral College

As a consequence of this being part of the constitution, it is very difficult to change. To just become a proposal an amendment requires a two-thirds vote in congress, and requires a three-quarters vote by the states to be adopted. Since the two major parties pretty much share the country, it would require all the votes of one party and around half the votes of the other party.

There have been many ways that the leader or leaders of group of humans is chosen, and there are many words that end in the suffixes -ocracy or -archy. All have their advocates and their denigrators. All have probably been tried somewhere at sometime or other.

In an attempt to define how a person should be treated and the rights that he or she should have, Eleanor Roosevelt chaired a committee which wrote the Universal Declaration of Human Rights, a somewhat fatuous document which was adopted by the General Assembly of the United Nations.

Article 21 of the UDHR talks about the right of everyone to take part in the government of his/her country, and implies but stops short of prescribing representative democracy. As such, the UDHR has plenty of “wriggle room” for alternative for other methods of government, as even a dictator could argue, and they often do, that what preceded them was worse and the dictatorship is merely a step towards returning or giving the power to the people.

(1) Everyone has the right to take part in the government of his country, directly or through freely chosen representatives.
(2) Everyone has the right of equal access to public service in his country.
(3) The will of the people shall be the basis of the authority of government; this will shall be expressed in periodic and genuine elections which shall be by universal and equal suffrage and shall be held by secret vote or by equivalent free voting procedures.

Many regimes though, don’t even try to argue they are merely filling a gap, but no doubt think that they are doing the best for their people. No one surely sets out to be a blood-thirsty dictator, after all. Arguably, though, a volatile country might benefit from a period with a strong leader, but eventually a strong leader will become succumb to a feeling of hubris and entitlement. Eventually he will be overthrown.

There exists a strong feeling that democracy is the best form of government that humans have tried. Whether or not it is the best system that is possible is another question. In a democracy everyone has a say and theoretically at least the government can be replaced, without revolution or bloodshed, if the population at large decides that it doesn’t like those it has elected.

Most democracies are representative democracies, in that the population do not normally vote on all issues, but elect a person to represent them in governing the country. Ideally such a representative would canvas or solicit views on topics that have to be decided, but in practise a potential representative will lay out his/her views and the electors pick the person who most closely fits their viewpoint.

Since this is done before the representative is selected, a future contentious issue may find the representative at odds with many of his constituents on the issue. While a good representative will make his views known and may solicit electoral views, and the electors can make the representative aware of their views by various means, the communication between the representative and his electors is to say the least inefficient.

A big thing about democracy is that everyone has at least one vote. In some systems a person may have more than vote, and in almost all democracies the voter gets a chance to vote to fill various roles, such as mayor, or sheriff, or local councillor. A democracy is an involving system, soliciting voter views on a periodic basis, so why don’t people get involved?

In the recent American Presidential election only just over 50% of the electorate voted, and this was in one of the most controversial elections of recent times. Since each candidate took almost half the popular vote only one in four voters voted to make Trump president. Of course only about one in four voters voted for Clinton (who got more votes than Clinton).

People don’t vote if they can’t be bothered, if they think that their vote will not make a difference and a small number don’t vote because they disagree with the process, maybe for political or religious reasons. The US is not alone in this, as a significant number of voters do not vote in an election in many democracies.

I would suggest that this is true in most democracies, but I don’t have the data. Some people suggest that making the voting easier by introducing electronic voting over the Internet, but I feel that this will not make a big difference. I feel that the reason for low turnouts is disinterest and a belief voting doesn’t make any real difference.

“For politicians, passing laws is like passing water,” said Narayan. “It all ends down the drain.”
Rohinton Mistry, A Fine Balance

Election promises are rarely believed and seldom acted upon. There is unlikely to be a wall built between the United States and Mexico. Trump has succeeded with that promise however, not because people believe that he will do, but because he most aligns with what people would like to do, and I don’t mean build a wall. He has proposed a solution to a perceived problem, and that is good enough for those who turned out and voted. Any solution that catches the imagination of the voters would have done as well.

Science has achieved marvellous things. It’s sent people to the moon, It’s reduced disease and the impact that disease has on people. It’s given us transistors, computers, the Internet and cell phones. It’s given us non-stick frying pans.

Science and its descendants, like biology, physics, and chemistry, and their descendants, like engineering, agriculture and medicine, have been an immense boon to the human race, to the extent that the human race would not have achieved the majority of things that we see around us. Railways, planes, roads and cars have all been achieved by the applied use of science.

Why then are people beginning to reject science and all that it has done for us? Why is there this anti-science, anti-rational groundswell, and does it really matter?

There have always been flat-earth proponents – people who disbelieve science, and bend the predictions of science almost to breaking point to favour their point of view. While they in general accept the facts, they do not like the conclusions drawn from the facts and build their own convoluted theories and explanations instead.

Then there are those who attack the theories of relativity. Here at least there is some justification as relativity is not easy to get your head around. It is not intuitive, and that is a weak way to some extent excuses the attacks on it. However the relativity opponents are generally unwilling to throw some maths at the problem – and without the maths, their objection do not stand up to scrutiny. In fact if they were to apply the maths, and were able to understand the maths, then probably the only conclusion they could come to is that the theories of relativity apply.

Many of those who oppose scientific theories do not understand what a theory is. A typical case is where someone declares that “evolution is only a theory“! What they don’t understand is that everything is a theory.

It is a theory that the sun “rises” because the Earth spins in its orbit, causing the Sun appear to rise in the East. (I’ve lost the Flat Earthers by this point of course). It’s a very good theory and one that is incredibly unlikely to be disproved, but it is still a theory.

Only A Theory

A theory is something that explains the known facts, and trying to dismiss something as “only a theory” pretty much amounts to dismissing all of science, as science is a network of interconnected theories.

This ignorance of what science is and theories are goes hand in hand with the simplified and cartoonish way that science is taught in schools. Here is an atom is behaves in so and so way, it reacts with these other atoms, and so on. Very little of the history of the development of the concepts is done, and unless someone gets interested and studies the roots of science, much of science becomes merely didactic and not fundamentally informative in any way.

Students do get told a little about how one theory may supplant another theory, but very often the concept doesn’t really sink in. A scientific theory is taught authoritatively – students are told that the ancient Greeks had some weak ideas which could barely be called theories, but Newton tossed that junk aside and used Reason to develop his theories. Then Einstein came along and “disproved” Newton’s theories.

There is an idea that theories can be discarded, but the next part, where another theory takes its place is skipped over or ignored. Inconvenient facts are ignored, or “explained” as errors or bias. It may often be implicitly or explicitly asserted that scientists have a vested interest or that there is a conspiracy to suppress the true theories.

There is one huge example, the tobacco industry, where bias and vested interests have had a negative influence on the science, and this, one can see, seems to validate the point of view that scientists are regularly distorting the results of science for their own ends.

So, it is not uncommon to have a case where people refuse to accept the science and go with their own views. One case that I saw recently was in a discussion of the so-called Supermoon on November 14th 2016 and the earthquake in North Canterbury, New Zealand early that same morning.

A SuperMoon is a perigee-syzygy, a new or full...
A SuperMoon is a perigee-syzygy, a new or full moon (syzygy) which occurs when the Moon is at 90% or greater of its mean closest approach to Earth (perigee). The March 19, 2011 supermoon is just 221,566 miles (356,577 kilometers) away from Earth. The last time the full moon approached so close to Earth was in 1993, according to NASA. it is about 20 percent brighter and 15 percent bigger than a regular full moon. (Photo credit: Wikipedia)

In the discussion several people were looking at the coincidence of the two events and linking them in their minds. After several people had pointed out that the science shows that there is no noticeable correlation between “supermoons” and big earthquakes, people were still saying that there must be something in it.

They had replaced the current scientific theory with their own thinking, without really explaining the facts away – there is no known or even noticeable link, and that lack of any apparent evidence should be explained by any replacement “theory” before any new theory can be put in place.

Similarly, I’ve come across people who oppose the use of fluoride and chlorine in public water supplies, and those who refuse to inoculate their children against diseases. In past decades people died from water-borne diseases, children have died from childhood diseases and whole populations have been wiped out. Children’s’ teeth have rotted in their mouths.

Why do these people do these things? In general they are fairly well-educated, fairly well read, and not unintelligent. Of course there’s a fear factor, but in previous generations fear was the thing driving people towards chlorination and fluoridation and inoculation against diseases.

However, I think that there’s more to it than that. There’s a rejection of rational thinking. They realise that science has done so much for them, yet they only pay it lip service. “Proof” of their views is obtained by scouring the Internet for the few dissenting voices. Any establishment voices are dismissed as biassed or merely toeing the establishment line. This is not a rational argument. A single or even a small set of dissenting voices is not proof of anything.

This worries me. We have always had the “alternative” views, the crystal gazers and the iridologists, but those people completely reject science as a world view. That’s OK. We don’t expect science from such people.

The antivaxers and the fluoride opponents however pay lip service to science while rejecting it, which is not logical. They know something of how science works, as evidenced by their rejection of current evidence of the benefits of fluoride and chlorine in the water, but they don’t follow through with meaningful data to support an alternative theory.

Well, as politics goes that was great theatre. Trump won when no one thought that he had a chance of even getting the nomination for the Republican Party. Trump as president is highly scary, not only for the US, but for the whole world.

Given that Trump is the man that he is, why on earth did anyone vote for him, let alone around half the people who voted? People have been puzzling the answer to this one ever since the election, and while it is clear from the statistics that there was a big swing to Trump by white non-college male voters – blue collar America.

Blue Collar Radio

It would easy to attribute this swing to gullibility and malleability of the non-college voters male voters. It would be easy to suggest that Trump’s evident charisma appealed to this sector of the electorate, but there must be more to it than that. Much more.

Notably the statistics seem to show that no other group of people fell for the Trump’s braggadocio like the white male non-college voters. Of course he turned off female voters to some extent by his behaviour and attitude towards women, but really, there was no huge backlash in that respect.

It seems that Trump’s call to “Make America Great Again” (trademarked by him in 2012) resonated with many Americans in this election, but it is not the first time it has been used. Several previous presidential candidates have used it. It implies that things were better in the past, but in general, that view is illusory, and one sees the past through rose-tinted spectacles.

“How many people long for that “past, simpler, and better world,” I wonder, without ever recognizing the truth that perhaps it was they who were simpler and better, and not the world about them?”
R.A. Salvatore, Streams of Silver

Another button that Trump pressed for many people, not the white, male, non-college voters alone was the race button. Technically one should not be called racist if what one says is the truth. Trump in many peoples’ opinions went a long way past that point.

While labelling Mexicans as all being drug dealers and rapist, he definitely went well past the point of propriety, but it appears that many people believe that there is a grain of truth there. In an American post-911 many people are wary of all immigrants, especially those from the Middle East. Again many people resonate with this.

Trump’s stated policies are ridiculous. Building a wall between Mexico and the US and making the Mexicans pay for it is silly, though I note that there are fences along much of the border already. A wall can be climbed over, tunnelled under, flown over or merely circumvented. All known walls of this type, Hadrian’s Wall, the Great Wall of China, the Berlin Wall, have all failed.

Trump threatens to catch and extradite all illegal immigrants in the US. Not only would this be fabulously expensive, it would cause immense upheavals and distress to many in the US, especially those families are mixed with legal and illegal immigrants. Apart from that the economy of California would collapse as many of the lower paid workers are illegal immigrants.

The threat to extradite all Muslims is not only silly, it is probably not legally possible. Many Muslims have been in the country legally for generations. A Muslim grandfather who came to America to escape conflict and even religious persecution in his homeland may face extradition merely because his sons or grandsons may at some time in the future become radicalised.

Trump’s policies may be ridiculous, they may be very expensive, but above all they may be impossible to carry out. Trump cannot write the laws himself, and there are some things that it may be legally impossible to do, and there may arguably be things that are constitutionally impossible to carry out. Trump’s policies may fail when confronted with political reality.

Trump appears to be passing off at least some of his powers to his Vice-President Michael Pence. This makes sense because Trump is a political novice and Pence has years of experience. At best this could make Trump look weak, and at worst, it could turn him into a puppet. As it is it seems that Trump is softening his stance on the issues that have assisted him to the Presidency.

This raises the question of what happens at the next election in 2020? If the Republicans don’t make any progress in addressing the issues that the white male non college voters have, if they don’t produce jobs, if people don’t see any progress in handling the illegal immigrant issue or the issues around Muslims in the US, it is hard to see him or the Republicans retaining the presidency and their ascendancy in the Senate and the House.

Trump could be a great president or middling president or useless president. While it is hard to read the future, going by his character, his lack of political abilities, the possibility that he will have roadblock after roadblock placed in front of him, and the almost impossible task of “Making America Great Again”, and the need to retain the loyalty of white, male, non college voters, I’m going to predict that he will most likely achieve very little, and will not get a second term.

In the mean time, while he is trying to actually achieve some of his goals, the Democratic Party has time to reflect, make changes especially to the party hierarchy and structure, and to win the loyalty of the voters. In particular they can reflect on what went wrong.

Would Bernie Saunders have done any better than Hillary Clinton? It is unlikely. The fact that Trump got selected for the race shows that voters wanted change and Saunders would most likely have provided a softer target for Trump.


http://www.gettyimages.com/detail/519579776

Should the Democrats select Saunders for President next time? Well, he is 75 now and will be 79 by the time of the next election, and that is ten years older than Ronald Reagan was when he became President. Incidentally Trump will become the oldest President to be elected when he is inaugurated.

I see some people are calling for Michelle Obama to stand in 2020. This doesn’t address any of the issues that this election has raised, so she would probably fail. In any case, she wisely says that she would not stand.

Measuring things

English: Ruler Italiano: Righello
English: Ruler Italiano: Righello (Photo credit: Wikipedia)

When we measure a length, with a ruler, say, we can’t measure it exactly. The ruler will be marked off in, say, millimetres, and the length we are measuring will probably fall somewhere between two markings on the ruler, so we can only say that the length is somewhere between the distance between the two markings and the start of the ruler.

Probably. Actually there are a number of things that could mess up our measurement. We may not be able to line up the start of the length we are measuring with the start marking on the ruler, as the marking on the ruler is not of zero width. The best we can do, when aligning one end of the length to be measured with the ruler, is to align the start of the length to the middle of the marking on the ruler.

English: A close-up picture of a section of ru...
English: A close-up picture of a section of ruler with British (inches) and Chinese (cun) scales on its two sides. This is the 10th cun – the last cun of a chi, so that one can see that 1 chi (10 cun) was equal to 14+5/8 inches, i.e. 371 mm. A metric ruler is shown next to it for scale. As can be seen from the worn corners, the ruler has been well used in measurements of length, such as perhaps of garment cloth, for trade transactions. (Photo credit: Wikipedia)

We then have to transfer our attention to the other end of the ruler. Probably the other end of the length and the edge of the ruler don’t align, so we shuffle the ruler to try to align the two ends of the length with the edge of the ruler, checking all the time that the start of the ruler is in line with the start of the length to be measured.

When all is aligned we can then read of the approximate value of the length, assuming that the ruler is still properly aligned and that the start of the ruler is still properly aligned with the start of the length. However, as mentioned above the end of the distance being measured will probably fall between two markings.

So any measurement with the ruler should be stated with an estimate of the margin of error in the answer. “About 73mm, with an error of about 0.5mm” might be a reasonable estimate.

The accuracy of a measurement may depend on the material from which the ruler is made. It may be wood, plastic or metal, or some other material. Wood is a natural material, and as such it may warp, or shrink or expand unevenly. It may deteriorate over time, so that today’s measurement may be slightly different from today’s. The ink used to make the markings may migrate into the wood through natural pores and cracks in the wood, rendering them wider and fuzzier than when the ruler is new.

Diagram showing operation of temperature compe...
Diagram showing operation of temperature compensated “gridiron” pendulum, invented in 1726 by British clockmaker John Harrison. The pendulum uses rods of a high thermal expansion metal, zinc (yellow) to compensate for the expansion of rods of a low thermal expansion metal, iron (blue), so the overall pendulum doesn’t change in length with temperature changes. Therefore the period of swing of the pendulum, and the rate of the clock, are constant with temperature. (Photo credit: Wikipedia)

A metal ruler can be marked more accurately, and the markings won’t blur, and the markings can be much thinner or sharper than those of a wooden ruler. Unfortunately metal will expand and contract depending on the temperature, adding errors to the measurements. This can be alleviated by careful choice of alloy for the ruler, but not eliminated.

All rulers are these days fabricated by machines of course, and the markings are made by these machines. Such a machine has to be as accurate or more accurate than the end product of course, which means that the scale marks must be located more accurately, and probably be narrower than those of the end product.

In order to be more accurate, various techniques are used to achieve the extra accuracy, and I’m not going to discuss them here, mainly because I can only guess what they are! Vernier scales and error averaging techniques spring to mind, but as I said, I don’t what is actually used.

Microscopes and similar allow the measurement of very small distances against a scale calibrated to very small tolerances. This pattern is repeated endlessly – to measure small distances accurately your measuring device (or technique) needs to be an order of magnitude more accurate than the distance to be measured.

If we want to measure atoms, we need an atomic sized scale and that cannot be made of atoms, obviously. We can use electromagnetic waves, other atoms, subatomic particles and so on, of course, but we are now in the quantum world, so not only do we have the sorts of issues mentioned above, but we have issues that related primarily to the quantum world – such as the Uncertainty Principle, and the fact that an atom can behave like a particle or a wave.

Down at these levels we use atoms to measure other atoms – there is of course no possibility of a ruler type scale which is made up of atoms. Instead things are measured by noting the frequency of emissions from the atom as its electrons changes from one quantum state to another.

This is referred to as a quantum jump and is popularly interpreted as an electron moving from one electron shell to another, in the common view of an electron orbit around the nucleus of an atom like a planet around a star.

A popular view is that at quantum levels the apparent continuity in time and space is not seen and that space and time appear to have a discrete structure. At some scale this makes it impossible to measure very small lengths, as it is impossible to tell whether or not two points are at different locations or not.

Dr. Max Planck

It follows that in the usual macro world that apparent continuity is probably illusory – if we can’t tell the difference between two points at a very small level, our measurements at the macro level are not well defined. It seems that the appearance of continuity at the macro level is an emergent phenomenon.

Maybe. The appearance of continuity probably comes from the fact that when we look at a line from A to B we can always pick a point C between them. We can then pick a point D between A and C and a point E between A and D and so on, apparently forever. But in fact the process has to stop, and the stopping point is where we find that we can’t distinguish the two end points of the line.

Is the issue caused by a conflict between our physics, which is at heart a description of the world as we see it, and what the world is actually like? A line is a mathematical concept which has extent (length), but no width. In the real world a line is marked by some means, pencil or laser beam, and has an extent, which is what we are trying to measure, and certainly has some width, the width of the lead of the pencil, the width of the laser beam. Are we starting to find out about the things that we can’t know about the world?

Virtual Reality


Embed from Getty Images

Back in 1999 I was just finishing my Masters degree at Victoria University of Wellington. I needed a subject for my research paper and I chose what was then a hot topic, Virtual Reality (VR). At the time, the computing resources that were available to most people were, by today’s standards pretty limited.

17 years ago we measured RAM in megabytes, and disk space in gigabytes. The Internet was not as pervasive as it is today, and most people, if they accessed the Internet at all, used dial up modems. Broadband was for most people, still in their future. As were smartphones and all the technology that we immerse ourselves in today.

As could be imagined, this limited the effectiveness of VR. If you were trying to set up a VR session between two geographically separated places, then the VR experience could be somewhat limited by the low resolution, the speed of updates of the views that the users experienced, and the lags caused by the (relatively) slow connections.

Nevertheless, research was taking place, and Head Mounted Displays (HMDs) and VR gloves were researched and developed. The HMDs provided the user with displays of the virtual world around him/her, and the gloves provided the tactile element to some extent.

English: zSight HMD by Sensics, Inc.

These devices have their current descendants of course, though more is heard of the HMDs than the gloves. The HMDs range from the highly developed devices like the Oculus Rift right down to cheap devices like Google Cardboard which literally that, a head mounted device consisting of a cardboard body and a cellphone. The cellphone’s screen is divided into two and different images are provided to each eye for the 3-Dimensional effect.

It was evident, back in 1999 when I wrote my paper that VR was a technology looking for an application, and it still is. Some TVs have been made which incorporate 3D technology, but the production of these appears to have tailed off almost completely. Apparently the added ability to experience movies in 3D which involved wearing special headsets, wasn’t enough to offset the necessity to wear the headsets.


Embed from Getty Images

People just used their imaginations when immersed in a program or movie and didn’t feel that they needed the extra dimension, and the headset added a barrier which prevented experience of shared movie watching that forms at least part of the entertainment value of watching movies with friends and families.

My paper was about diffusion of VR techniques into everyday life, and it mostly missed the point I think in retrospect (though the paper did help me get the degree!)  My paper used a Delphi Technique for the research. This technique involves posing a series of question on the research topic to a number of specialists in the field. Their answers are then summarised and passed back to the whole panel. Any subsequent comments are then also summarised.

Obviously as workers in the field my panel was positive about VR’s then prospects, as you would expect. They however did sounds some notes of caution, which proved to be well founded. I’m not going to do a critique of my paper and the panel’s findings, but I will touch on them.

Specifically, they mentioned that my questions were all about fully immersive VR, which is basically what I’ve been talking about above, the HMD thing. Augmented VR, where our view of the world in not (fully) obstructed by the technology, but the technology enhances our view of the world is used much more in practise, and was when I wrote my paper too.

Augmented VR is things like Head Up Displays (HUDs) and Google Glass where information is added to the user’s field of view, providing him/her with extra information about the world around him/her is much more common. HUDs are common in planes and the like where the operator cannot spare the time to go and look up important information so the information is projected into his field of view. Google Glass was similar but allowed the user to feed back or request information, but unfortunately this did not really catch on and was dropped.

I mentioned in my questions to my panel that maybe the speed of the Internet was a barrier to the introduction of VR into everyday life. The panel were mostly sympathetic to this viewpoint, but in summary thought that fibre, which was on the horizon would significantly reduce this barrier to the everyday adoption of VR techniques. In fact people do not use the extra bandwidth for VR (except in a way that I will touch on in a minute), but for other things, like streaming TV shows and downloading music.

As I envisaged it, a typical VR setup would consist of someone in, say, London, with VR set interacting over the Internet with someone in, say, Tokyo who also has a VR set. They could shake each other’s hand, and view and discuss three dimensional objects in real time, regardless of whether the object was in London or Tokyo. Although I had not considered it at the time, a 3D printer could duplicate a 3D object in the other location, if required.

This has not happened. Teleconferences are stubbornly 2D, and there is no call for a third dimension. Some people, myself included, would not miss the 2D visual aspect at all, would quite happily drop back to voice only!

FEMA’s National Response and Coordination Center (NRCC) is activated at Level 2. FEMA/Bill Koplitz (Photo credit: Wikipedia)

In one respect, though, VR has come and has taken over our lives without us realising. When we interact with our smartphones, texting, sending photos, emails and so on, in real time, we are immersing ourselves in a new sort of VR. When we are chatting about something and someone gets the cellphone out to google the Internet to check or look something up, we are delving into a new Virtual Reality that we could not have envisaged way back in 1999.

So when I look back at my paper from that era, I could easily update it and make relevant to the current era, but only in the respect of that limited view of VR. That has not really eventuated, and most likely will have limited application (remote appendectomy anyone?), but it could be considered that facebook/twitter/google/gmail/dropbox and all the other tools that we use on our smartphones has opened up a different alternate Virtual Reality that crept up on us while we were not watching.
