Photography – Yet Again

Gum Grove path

Path to Gum Grove

I wondered if I had ever written a post about photography. So I checked. The answer was that I’ve done quite a few. Oh well, it’s a big subject!

I don’t count photography as a hobby of mine, but more as an interest. I’ve got a camera, but it is only an enhanced point and shoot, and I sometimes even use the camera on my cellphone. I haven’t bought any camera gear and I probably won’t. Handheld is good enough for me.

Of course photographer want the best picture that they can get, so better cameras and lenses are the way to go, and probably a tripod would be the next buy. Special filters and accessories enhance a photographers art and this can get expensive. Not to mention bulky and hard to carry around.


Old and New

I have nothing but admiration for those photographers who will hike kilometres and wait for hours for the right light to capture a particular shot. I’m usually constrained by a number of things that need doing, plus I usually have a dog attached to me when I have the opportunity to snatch a picture.

Nevertheless I try to take good pictures. I might spot the opportunity of a picture and I wrap the dog’s lead around a convenient tree while I compose and take whatever has caught my eye. I usually take a few shots of the same subject to enhance the possibility of one of the pictures being an acceptable one.

Usually I don’t fiddle with the camera settings, some of which are meaningless to me anyway, but occasionally I will experiment with the shutter timings and the aperture settings. I say “shutter” but I’m pretty sure that my camera doesn’t have a shutter.

I have to trust the autofocus as there is way on my simple camera to easily adjust the focus. I can lock in the distance setting by partially pressing the button, and I have done so in the past, with variable results.

One consequence of the digital revolution is that the potential picture is displayed on a LCD screen rather than through a viewfinder, and these are often difficult to see and compose a picture in. I sometimes take a few pictures of my subject from different distances and different angle, but composing a picture is still difficult.

Fortunately my camera is pretty clever, and the focussing is usually better than I expect. Composition is pretty hit and miss for the reasons I mention above. Usually there is at least one photograph from the many that I take which is acceptable and many are better than I could hope for from my somewhat random shooting method.

It’s not quite a “Monte Carlo” method of taking photographs, but it is close. It’s not often that I get a picture which is better than merely “good”. But even then the picture will not be razor sharp, and serious photographers would probably look down on them. That’s OK, as I don’t aspire to having them blown up to A4 or even A3 and hung on a wall.

So, why do I take photographs? Well, I do post a lot of them on Facebook, so I must feel the need to get others to look at them, and hopefully they will like them and if they like them or don’t like them, hopefully they will say so.

My Facebook pictures are public, but most comments come from friends and family, which is understandable as I don’t do anything to publicise them. When friends and family comment on them, others may see the pictures so they do find their way out there.

Facebook and other “social networking” apps have changed photography for me and for millions of others. Without Facebook taking a photograph of oneself is a bit pointless. Who would ever see it? But “selfies” allow the photographer to include his/her self into a picture.

First Bridge

The First Bridge

It’s a form of bragging. The selfie taker is boasting : “Here am I and here are my friends, and we are having fun, in this indiscernible location, and we are drunk as skunks”. OK, well, some selfies are taken in recognisable places and the selfie taker is not under the influence of alcohol, but many, many are.

So the pictures that I and other serious and not so serious photographers post to social media are usually not selfies and most often don’t contain babies, other children, pets and people grinning at the camera. The pictures that I and other posts are in the minority, and of course there is a huge number of pictures that fall into both categories, the trivial and the hopefully not so trivial.

Autumn Colors

Autumn Colours

For instance, the pictures of dogs running where you can’t see their legs and so they appear to be floating are funny, essentially trivial, but make a good photographs, even if it transpires that the pictures were serendipitous. The stunning picture of a sunset taken on a honeymoon, may be snapped on an iPhone, and is arguably less trivial.

I mostly like to take pictures of fungi, flowers and trees, not to mention insects and other small animals. I see beauty in a spider or beetle or slug and often try to bring this out in my pictures. Also in fallen leaves or leaves with autumn colours, or the small flowers that others refer to as weeds, but which repay a closer look. Often the structure of such small plants is amazing.

Basket Fungus

Basket Fungus (Ileodictyon cibarium)

I also take pictures that I think of a “records”. Such as the time when the stream turned into a raging torrent during a big storm, or the moment when a Monarch butterfly hatches from it pupa. While some of these may transcend being a record of the event, many are interesting but less of a photograph and more of a picture. The lighting many be wrong and the image fairly dark, but it still shows the insect expanding its wings from mere sacks to the beautiful wings of the complete insect.

There’s nothing wrong with selfies and other similar photographs, but one would hope that the selfie taker would graduate to something better eventually. If what I might term a “proper” photograph is actually better in any real way.

Shadows of Reality

Plato’s Allegory of the Cave has people chained in chairs facing a blank wall. All that they can see are the shadows cast on the wall of the cave. When they break free from their chains they discover that reality is not what they believed it to be. In particular, they don’t know what the sun is, having never seen it before. The implication is that we cannot know reality and that we only see shadows of it and must make do with that.

It’s a nice analogy, and presages Kant’s noumenon and phenomenon, where phenomenon is what we sense or perceive and noumenon is what gives rise to phenomenon. Noumenon is fundamentally unknowable through human sensation, and perhaps corresponds to Kant’s “Ding an sich” (thing-in-itself), which I think of as the thing that gives rise to perceived phenomena, but is not and cannot be experienced through the senses or by other means (if such exist).

The nice thing about allegories and analogies is that you can play around with them. Of course, if you push them too far they fall apart, but that is part of the fun. I’m going to push the Cave Allegory a little bit.

You see, the people in the chairs are not entirely without information about the outside world, aka reality. If the shadows move across the cave wall and they are not moving, then something else is! They won’t know what is causing this phenomenon, but they will notice that it changes in a fixed cycle. The shadows sweep across the wall, only for everything to go dark, and then everything repeats. Let’s call it a day.

If the people in chairs watch for long enough they may determine that there longer cycles. Sometimes the shadows reach higher up the walls, and sometimes they are lower. Let’s call these longer cycles years.

When one raises his hand one of the shadows changes. Some of the shadows are apparently related to the people in the chairs! The person in the chair will most likely come to associate one of the shadows with him/her self, and by extension would assume that some of the other shadows are people also.

He or she might not realise that his/her body is actually seated in a chair, and that the shadow which he/she associates with his/her self are merely outlines. This is a scary thought – if the analogy holds, is it not possible that the same is true of us? We may be seeing shadows and concluding that we are the shadows. Maybe there is a wider reality outside of our perceptual cave and we only need to turn around to see it.

However, just like the people in the cave, if we did wake to a wider reality, we probably would not understand what we are seeing – the people in the cave, when they freed themselves, found the sun to be incomprehensible.

I just realised that in Plato’s original allegory, the light that threw the shadows was not the sun but a fire. I’m going to acknowledge my mistake but let it stand, as it makes my point that the people in the chairs are not completely without clues about the wider world, even if their interpretations are wide of the mark.

Science and what was previously known as ‘natural philosophy’ are attempts to describe the shadows that we see. One of our shadows is the rising and setting of the sun. I’ve described elsewhere that the extreme doubter, the ultimate sceptic, doubts that we will see another sunrise, or rather, cannot see any way that we can know absolutely that we will see another sunrise (leaving aside for arguments sake the possibility that we drop dead – that is not what the issue is).

I don’t actually believe that we are sitting in any conceptual chairs, so we can’t leap out of them to get a wider view of reality in the sense of the allegory, but we do describe the world in terms of what we see, just as those in the cave do. We have no better access to reality than they do. We just have a better class of shadows as it were.

That’s why I find it amusing when the headlines read that scientists have found the Higgs Boson, or that they have detected gravity waves. Oh really? I do not suggest that the Higgs Boson has not been “found” or that gravity waves have not been detected, of course, but no one have ever seen the Boson or watched a gravity wave passing by.

No, what they have in fact done is theorised about these things, designed experiments that should show a blip in a graph or find an anomalous number in the printout of their experiments, and this is what they see. They see the predicted blip or the anomalous number.

These results however based on existing theories. Starting from theories about matter and what it is made of. Atoms, you say? Oh OK, we have experiments (from long ago) which show that matter is made up of atoms. We know a lot about atoms from experiments and theories, but no one has ever seen one or held one in his/her hands. We are sure, though, that matter is basically made up of atoms.

However, certain results of these experiments lead to the question of what atoms are made of. So we end up with a (very accurate) theory and experiments which show the existence of sub atomic particles. Some of these theories lead to the theory of the existence of the Higg’s Boson. It is required if some of the theories are correct.

I don’t know the details, but experiments have been done which reportedly appear to show the existence of the Higg’s Boson. What they show is results which are consistent with the stack of theories the top one of which predicts the existence of the Higg’s Boson, and the lower theories predict various behaviours down to the lowest level, those that theorise that matter is fundamentally atomic.

Those are our shadows on the wall. We describe what exists by using theories based on what we can see. We see the blip in the graph, and celebrate our theory which is underpinned by other theories down to the lowest and most general theories. However, we can’t get out of our allegorical chairs and turn to actually look at what exists. That’s where the analogy breaks down – there are no chairs and there is no wall. However what we are looking at are shadows.

The Tyranny of the Minority

It would be nice if everyone could agree what is fair and what is not. In an ideal world a believer in a religion would agree with a believer in another religion that they both have the right to believe as they wish. Instead we find believers in one religion continuously killing believers in another religion.

One of the problems is that the holy books TELL believers to kill, in various dreadful ways, those who do not believe in the holy books, so for a believer the killings are justified. Naturally those being attacked also have a holy book that tells believers to kill non-believers, so we have a religious war.

This book is considered the most important of ...

This book is considered the most important of the Baha’i faith. Kitáb-i-Aqdas (The Most Holy Book, 1873) is, however, NOT translated into Swedish yet, and no layout for the front has been devised or developed. Therefore I have created a dummy cover, a pretended cover, with the intention to illustrate a wikipedia article about a book that eventually will be translated into Swedish. The appearance of the Aqdas in Swedish and its face is completely my own invention. (Photo credit: Wikipedia)

Most religious believers would probably characterise themselves as “moderate” believers and would probably condemn those extremists and countries that practise killings in the name of the religion. They would point out that when the deity instructed believers to kill, it was in specific historical circumstances (such as when followers of another region were trying to wipe them out) and that to apply the injunction in modern times is perverse.

Most of the time, I’d suggest, the average believer would be happy to get along with believers in another region, but is instructed to shun them by a small number of “militant” believers and teachers. The would be moderates are bullied and coerced by the militants into actions which they would not normally contemplate.

Of course, such things don’t just happen in religious societies. When people see their standard of living fall, when they are thrown out of jobs because the jobs are being shipped overseas, or because technology is making their jobs redundant, they may fall under the sway of someone who tells them that their situation can be improved and that person if the best person to achieve that feat.

It helps if the person is charismatic, if the person claims that he/she is going to overturn the traditional ways of doing things, if the person is not part of the establishment, if the person intends to disrupt the current ways of doing things.

What actually happens is that the the person stumbles when he/she tries to shake things up. Some things will change, but far more things will remain the same. Many processes and procedures have reasons for their existence, though it is good to challenge them now and again.

My point is that the directions of our lives are directed and controlled by a small number of people. They may be politicians, or business people, or religious leaders. We may get to choose between them, but as types, politicians are very similar, regardless of party affiliations. Generally they are leaders while the rest of the population are followers, just getting on with their lives, trusting the leaders to lead us in the right direction.

This is a workable model, and has served us well for the most part. Sometimes a maverick comes along to lead us in a direction that in retrospect seems bizarre or counter intuitive, and the unmotivated majority is dragged in a direction that they would not have wanted to go. Sometime a leader is so powerful that he/she does things that give him/her power over the population that they would normally not cede to the leader, and we get a depot or dictator. But dictators die and rarely are they followed by an equally despotic ruler.

We pretty much expect others to, basically, run the country for us, but I’ve noticed in recent years the rise of a new type of tyranny, the tyranny of the minority. A few people, for their own ends, prevent the silent majority from having what they want.

For instance some people refuse to have their children immunised, which means that their children can catch diseases and while the disease may turn out to be mild for their children, their children can then infect smaller children who are too young to be immunised and who may react badly to the disease. Children die in this manner, and this is preventable.

If there was a law that all children hove to be immunised, then these deaths could be prevented and as a bonus the disease could be wiped out. In my opinion anyone who lets their child become a carrier for a disease should be charged with manslaughter as the very least.

Most people are happy with chlorine being added to tap water. It ensures that tap water is safe to drink. However in the developed countries a militant few are campaigning to stop chloride being added to tap water, and in some places they are winning. They are winning by using scare tactics and misinformation.

This anti-chlorine web page is typical and uses both techniques. Firstly it mentions that “chlorine gas was used with deadly effectiveness as a weapon in the First World War.” This is a fact, but it is also a big scare as the concentrations of chlorine gas used in the First World War were massively higher than the trace of chlorine left in tap water by the disinfection process.

English: Using a pool chlorine indicator to te...

The same amount of chlorine gas is made with addition of acetic acid as without acetic acid. (Photo credit: Wikipedia)

Secondly, the article mentions that “a recent study conducted in Hartford, Connecticut found that women with breast cancer have 50-60 percent higher levels of organochlorines (chlorine by-products) in their breast tissue than cancer-free women”. This is misdirection as there is no evidence that the organochlorines entered the body through ingested water.

Did I mention that the one person quoted extensively in the article was employed by a filter manufacturer? Shame on Scientific American for publishing an article with such an obvious bias.

This is one way that the minority tyrannises the majority. They come up with spurious and unscientific arguments that are plausible to many people and persuade the authorities that they will launch lawsuits if the authorities persist in whatever the minority doesn’t like. They demand their “right” to chlorine free water, or bread without folate, or the right to not have their children vaccinated, or similar.

This denies the rights of the majority, who either want chlorine, folate or don’t want disease carriers giving whooping cough or measles to very small children, or more likely don’t care one way or the other, but accept that what the authorities are trying to do is beneficial. Which stinks, in many ways.

What is truth?” Pilate asked of Jesus. Jesus had just asserted that he had come into the world to testify to the truth. Pilate used this to close off the conversation, as he knew that truth is exceedingly difficult to define, and that one man’s truth is another man’s falsehood.

We live in a world where politicians cite “alternative facts” to defend themselves when their statements are questioned. Hmm. This seems like a step on the road to fluid “truth” of the authorities in the book “1984”, but is more likely to be a scrambling attempt of the establishment to defend itself.

Philosophy is a means of addressing Pilate’s question and many many others that do not fall into the realm of science or of mathematics. What is real and can we know it? Can we know anything? Is there a God, and if so, why does he permit evil into His universe?

These are questions which fall into the realm of philosophy, as do others about the meaning of science and mathematics, and questions of ethics and morals.

Raphael's "School of Athens"

Almost by definition, philosophical questions cannot be answered. The “What is truth?” one is a prime example. Will the sun rise tomorrow morning? Did the sun rise this morning? Is the sun risen at the moment? All of these questions can be pragmatically answered “Yes!” but probe a little deeper and the answer can appear less definite.

After all, we might remember the sun coming up this morning, but what if these are false memories. Or maybe what we see is a mere “virtual reality” fed directly to our brains. And just because the sun rose this morning, and the morning before, and so on, doesn’t mean that it will rise tomorrow. Maybe there is some as yet unknown physical event that will cause it not to rise. Maybe cause and effect are illusions and anything can happen.

We nowadays separate science and philosophy, but this was not always so, and science was once termed “natural philosophy“. The ancient Greeks would have been termed philosophers, but they dealt with such questions as what everything is made of. Some of their suggestions would seem quaint today, but they did suggest the concept of atoms.

At the time there was no way that any of their hypotheses, such as the atomic hypothesis, could be tested and some of them even thought that testing them was a bad idea. They meta-hypothesised that everything could be deduced simply by thought. They needed no experiments!

In the scene depicted, Crates is trying to dissuade Hipparchia from her affections for him by pointing to his head to show how ugly he is. (Photo credit: Wikipedia)

Atomic theory is now definitely in the realm of science. Biology too, and mathematics, though maths now has its own realm, apart from science. Anything that is in the realms of philosophy may find its way to the realm of science or maths.

What about things like ethics and morality? Surely these won’t ever move to the field of science? Well, maybe. I wouldn’t bet on it, though it may be a long time before there is an ethical Newton, a morality Einstein.

Sir Isaac Newton

Science has made great grabs in recent times for the fields of behaviourism and in studies of human consciousness. These have been until recently the domain of philosophers alone. In a way, it might be better if we did not understand the way that people and societies and human consciousness work, because understanding things is the first step to control things. Let’s hope that the ethical Newton and the morality Einstein arrive before we know how to scientifically control people and societies.

Philosophic pondering on the way things are tend to be wild and diverse. We tend to think of such hypotheses as the multiple worlds theories as new and cutting edge, but Professor Pangloss in Voltaire’s 1759 book “Candide” proclaims that “all is for the best” in this “best of all possible worlds”, which implies that there are, or could be, other worlds where things might be different.

(Photo credit: Wikipedia)

Of course, since there was no real divide between philosophy and science and maths in the early days, we can’t really say that science has taken over these philosophical topics, more that they have been hived off as science split from philosophy. Nevertheless, science is probing topics, such as the nature of reality, which definitely have a philosophical flavour to them. For instance, is the cat alive or dead, or maybe both?

The philosopher Zeno of Elea introduced some paradoxes which even today exercise the minds of philosophers and mathematicians. Basically, Zeno poses the question : How does one (or an arrow for that matter) move from point A to point B? There’s plenty on the Internet about these paradoxes, so I’m not going into them in detail, but essential the core of the problem is how to sum an infinite number of increasingly small intervals of space or time without the result becoming infinite.

English: The Zeno Paradox in portuguese. Deriv...

Obviously Achilles does overtake the tortoise, the arrow does reach its target and it is possible to travel from A to B, but some people still think that science and maths have not yet solved these paradoxes, and there’s still a sliver of a problem for the philosophers. Arguments these days resolve more around whether the paradoxes have been resolved and therefore we can move from A to B, or are still in the realm of philosophers and therefore we cannot move from A to B!

When the Greek philosophers were thinking about atoms and what things are made of, there was no way to test the various theories out. When they were developing theories about the stars and other astronomical objects they had no way to test the theories out. However, eventually the “natural philosophers” like Newton, laid the basis for astronomical theories, and early chemists like Lavoisier laid the basis for the science of chemistry, which made use of the theory of atoms.

Philosophy exists because people like to ask questions like “What is beyond the end of the Universe?” or “If God made everything, who or what made God?” Or “How long is the hypotenuse of a right angled triangle with sides on one cm or one inch?” Or “Why is the ratio of the circumference to the diameter of a circle a fixed number and what is it?”

Philosophy exists to postulate parallel Universes, massive balls of fusing gas, and terrestrial planets complete with humans or maybe little green men. Its job is to wonder what lies beyond the bounds of science and what makes humans behave the way that they do, and whether or not God is dead. It is to ask the impossible questions. It is science’s job to prize these issues from the hands of the philosophers and answer them.

Getting the Wind Up

A plant disease called “myrtle rust” has appeared in New Zealand, apparently after the spores have been blown across the Tasman sea from Australia. That’s over four thousand miles. The prevailing winds are from Australia to New Zealand and the cyclones and storms that hit New Zealand are formed in or off the coast of Australia, or further north in the Tropics, or further south in the Southern ocean.

In these areas low pressure areas form and consequently winds blow from the surrounding areas of slightly higher pressure into the lower pressure area and start to swirl clockwise. The clockwise movement is the result of the Coriolis effect, which is difficult to explain, but relates to the fact that when an object moves north or south on the rotating Earth, it moves closer to or further from the Earth’s axis of rotation.

A low pressure area sucks in air and it is forced up in the centre where it cools and forms clouds and rain. As this process continues, the pressure at the centre of the low drops and the spiral of winds gets tighter and, if the low is very deep, more destructive. I’m not sure why a low deepens, when one would think that all the in-rushing air would fill the low, and the few explanations that I have read have not convinced me.

On a larger scale, bands of winds circle the Earth, with winds coming from the west in the south and the north of the two hemispheres, with prevailing easterly winds nearer the Equator in both hemispheres. The sometimes destructive cyclones and anticyclones are mere ripples in this larger flow.

Even in quiet wind conditions there is usually a breeze, often stimulated by local conditions, such a large lake or sea. All that is required for a breeze is a small differential in temperature, with local heating expanding the air or local cooling causing it to contract.

The sea will absorb heat from the sun more slowly than the land, and the air over the land is therefore warmer and becomes less dense. Consequently a breeze develops flowing from the sea to the land. The reverse occurs at night, when the land cools more quickly than the sea. Such conditions are however very local and are often unnoticeable and overridden by cyclonic and anticyclonic wind conditions.

Within a large weather system, such as a cyclonic system, local conditions may affect the wind directions and strength. Often the wind direction and strength varies widely locally, giving rise to conditions that are described as “blustery”. While such conditions may be good for drying laundry, they making sailing a difficult pastime. Sailing races can be won or lost depending on whether or not the sailors catch the good air or fall into a pocket of stale air.

The strength of the wind obviously varies tremendously. At the one end of the scale a breeze may cause a flag to limply stir, while at the other end of the scale, a really large storm may uproot trees and destroy houses. In some parts of the world tornadoes may form when weather conditions are right and may sweep destructively over the land, ripping apart anything that stands in their way.

There is energy in the wind, and efforts are being made to economically harvest this energy to reduce our reliance on fossil fuels. Such fuels are not infinite, and we will sometime or other run out of them. It may be that we have enough fossil fuels to last centuries, but getting at them involves the disruption of mining, and as they are used up, mining will become even more disruptive than it is now. Mining even small amounts will become very expensive.

It makes sense to develop machines to harvest wind power, and the signs are that this is becoming economically more competitive. At one time, before petrol engines became common, the only ways to power transport were wind and steam, and it may be that petrol and other fossil fuelled engines may only have a relatively short time span of usefulness, maybe only a century or so.

We also use fossil fuels for our plastics. Almost everything in our modern world has a large proportion of plastics in it, sourced almost entirely from oil. It remains to be seen if we could replace our need for fossil resources from renewable resources.

Hay fever suffers may curse the wind as it blows pollen up their noses and into their respiratory systems, but many plants rely on the wind to propagate themselves. A case in point is the myrtle rust I mentioned at the start of this post. Plant pollen can travel thousands of kilometres and fall all I know can circle the Earth. It’s an efficient way of spreading the reproductive material, but its a really inefficient way of getting the reproductive material to a member of the species of the opposite gender.

Obviously it works best where the plants are grouped together, and it works even better if the plants are hermaphrodites, but it does work (occasionally) when the plants are far apart. This mechanism for reproduction probably arose a long time ago before plants invaded the land. plants growing in the sea, and many animals too, just broadcast their gametes into the sea and trust in at least some of them finding other gametes so that they can grow into mature individuals. (Caution: It’s complicated!)

We often hear the sound of wind. It can be caused by wind blowing through trees or other plants. It can be caused by wind blowing through gaps in our houses, mainly doors and windows. We build our houses to protect us from the wind and other aspects of the weather, as a sort of synthetic cave, I guess.

We can even make music (well, musical sounds) using the wind. Many people have “wind chimes” which are metallic objects strung on wires arranged so that the wind can bash them together, making a chiming noise. Some people like them, and others dislike them (I fall into the second camp).

Strings can be placed on a sounding board and used to produce musical sounds, and such “Aeolian Harps” were once as common as wind chimes. An accidental Aeolian harp can be heard in the sound that power and telephone lines make when a strong wind blows.

Waiting on God

I hate getting older. I hate the sensation of slowly losing my faculties. For example, I’m proud of my vocabulary, but these days I sometimes cannot bring a particular word. Or another word slips in in its place.

For example, above I wrote “facilities” first, and then realised that I meant “faculties”. Words which I would have written without even thinking suddenly are suddenly tricky to spell. “Thought”! Is that “ght” or “gth”? I used to be able to write whole paragraph without seeing the wiggly red line even once.

Even worse, when I’m talking to someone and I pause to collect my thoughts and work out what I am going to say next, they try to finish my sentence! That is incredibly annoying, but people seem to think that it is funny. The only time that someone finishing someone else’s sentences was in a sketch by Ronnie Barker and Ronnie Corbett (“You Can Say That Again“).

One’s mental faculties reach a peak at sometime between 20 and 40. Babies are born with immature brains and our early life consists of us learning how to get on in life and at the same time allowing our brains to mature. From then on our brains start to slowly fade over time.

Our memories and our ability to access them slowly decline. I’ve always been quite good at quizzes and I hope and believe that I am still good at them. However I do know that I can’t access answers to quiz questions as fast as I used to be able to do, and quite often I find that I can’t recall an answer at all, only to realise, once the answer has been given, that I knew it all the time. I couldn’t recall it at all, but it was there, in my brain, but inaccessible to me.

The abilities that we have built up over the years after we became physically and mentally mature by offsetting the start of the loss of brain cells with experience start to fade as more and more brain cells die and lesser used abilities start to be lost. If you haven’t played golf in a while or ice skated since your twenties, if you try to take up the sport again, you will have to relearn it.

Since the circuits have not faded totally away you may achieve some level of competence fairly quickly, but you will never reach the height of ability that you had in your twenties. Even if you don’t give up a sport your abilities will fade, just not so quickly as if you had taken a break from the sport.

I was trying to make this post about me but I’ve drifted into generalisations. I’ve not retried a sport that I was good at, as I was never that good at a sport, but I have tried ice skating and roller skating after not having done it for a while, and I was able to manage it pretty well and pretty quickly too, so I think that I can vouch for my statement above.

One’s senses also decline with age. In particular, eyesight fades noticeably for most people. Things like cataracts and other conditions can only partially be mitigated. Spectacles tend to get stronger and the muscles that focus the eye deteriorate as other muscles do.

I’ve worn glasses since I was a teenager, that is, for most of my life. I can vouch for the fact that my eyesight has got worse over the ensuing decades, though I can see most things fairly clearly. I can’t easily read the small typefaces that are usually used for the ubiquitous “Terms and Conditions” found with appliances and contracts, but I suspect that the type has also diminished over the years and that the firms that supply the product or commodity hope that no one read them anyway.

The other senses also fade as the sensors and nerves age. Things taste blander, smell less fragrant, touch becomes less sensitive, and hearing tends to fade too. I’m fortunate that my hearing has not, as yet, been severely impacted, but I do suffer from tinnitus intermittently.

Taste is an awkward one – as one’s sense of taste declines, so, potentially, does one’s ability to digest food. The complex mechanism that is our digestive system of develops problems as we age, meaning that we may need to switch to less spicy foods, and since the sense of taste is declining, everything may taste even blander!

Joints wear as we get older. So do the ligaments that connect to them. Muscles become less effective. Balance, which depends on certain nerves in the ear, may be affected by the general decline of the nervous system. As I said above, my hearing is still pretty good and maybe as a consequence my balance is still pretty good, fortunately.

My joints do give me trouble some of the time, especially my knees. That’s something of a family joke as my father has had knee problems. He has had both knee joints replaced. My sisters also have issues with the knee joints and so do my daughters. We’ve all inherited the family knees, apparently.

People are living longer than ever before, but this is for many a mixed blessing. My father and mother are both still alive at more than 90. Fortunately they are still both pretty well, and although they do have some problems, both mental and physical. Others are not so fortunate and may spend years or even decades crippled by arthritis or a stroke, or severely constrained by some condition or other.

My biggest nightmare, as I grow older, is that my mind will fade away, or I suffer from some long term debilitating illness. I had a heart attack many years ago and in many ways it would be preferable, at least to me, for me to die suddenly from another one. Of course it would be traumatic for my family, but I’d hope that they would know me well enough to realise that I would prefer it that way.

Shift to the Right

All around the world, it seems, in the so-called democratic Western societies there is an ongoing shift to the right. What does “a shift to the right” mean? What does “the right” mean in the context of modern politics?

In the past the right stood for monarchy, the status quo and conservatism, while the left stood for republicanism, revolution and change, and socialism. The right is seen forward-looking and the left is seen as backwards looking.

The right has come to espouse the capitalist view of economic matters, and the concept of free markets where there is no regulation of the market and the left has come to mean stiff market controls and social ownership of some of the more important resources, such as the roads and other infrastructure, the police, and bounds on firms and corporations.

While the right tends to individualism and capitalism, the left tends to collectivism and the rights of individuals as part of a group. In the public mind the businessman is the epitome of the right while the worker represents the left.

But why are right-wing parties gaining control everywhere? The answer is of course in the rise of Islam and of ISIS and the militant Islamic movements in many countries, coupled with the floods of refugees from countries where Islamic activists are waging war against the authorities.

The refugees came not only from states where the Islam factions were looking to take over, but also from other countries, such as Ukraine, where Russia is looking to extend its interests into the country, which it lost when the old Soviet Union was dissolved. There are also trouble spots such as Israel where minorities feel threatened and are abandoning homes and heading to other countries.

People in Western bloc countries have seen on television news and elsewhere how these floods of refugees are causing problems because of the inabilities of countries in the path of the refugee flood to cope. At the same time they have seen on the news of the atrocities caused by radical Islamists close to home, in London, Paris, and in the USA.

This has naturally led to a rise in xenophobic distrust of those people who might be Islamic extremists and to the influx of refugees in general irrespective of their religion or beliefs. The feeling is that Islamic extremists could enter a country in guise of refugees, with intent of setting up branches of terrorist organisations.

That may be true in a very few cases but many cases the terrorist incidents have been perpetrated by people from the country that the incident occurs in, who have been “radicalised” via the Internet. While it is or may be true that the incidents are orchestrated by those outside of the country, few seem to be perpetrated by actual refugees.

Generally refugees are glad to be taken in by other countries and are also glad to fit into those countries and be accepted by the people who live in those countries. Most are appalled by the violence done in the name of their religion and don’t believe that their religion actually requires believers to do these things.

Refugees are usually happy to fit into a country which allows them to practise their religion quietly and privately. Most Christians would say the same, regardless of which denomination they belong to. If you espouse a religion aggressively, then this would cause issue with your neighbours and merely repeats the problems of your original country.

Since I do not believe in religion, but do not object to people who practise one, I see no problem, provided the believer doesn’t try to force his/her religion on me. I will happily take part in a marriage or naming ceremony in any religion, and not just in the Christianity which I was nominally raised in.

The seeming daily “terrorist” acts have scared people. They now look askance at anyone who worships differently from them, and who dresses differently. This has led to many refugees who do not espouse the local religion or customs, adapting, so that they don’t stand out from the locals.

There is a constant dialectic between the religion and customs of their homelands and the new country to which they have moved. The refugees do not want to lose their culture, which they see as a rich heritage, which it is, yet they want to conform and fit in to their new country.

Many people in countries to which refugees move see refugees as different. They don’t understand the customs, they don’t understand the religion and they don’t understand why the refugees are not exactly like them. They are worried that the refugees may be terrorists in disguise, but rationally, a terrorist is more likely to adopt local customs and dress, so that he/she doesn’t stand out as different.

This difference engenders fear, and I’ve seen this before. In the ’50s, ’60s and ’70s many West Indians came to Britain, changing the face of the country. Many British people had not seen anyone with a dark skin before, and this shocked and in some cases horrified people. Uneasy jokes were made as how the West Indians were taking over the busses, as drivers and conductors. The tension led inevitably to the rise of the National Front party.

Thankfully the British people eventually accepted the West Indians into the country, and while there were a few incidents over the years, the British people have tolerated incomers pretty well overall.

Nevertheless, in many countries, especially those on the route of the fleeing refugees, there has been a resurgence in the nationalist movements, which laughably indirectly led to the right wing United Kingdom Independence Party congratulating itself for being annihilated by the Tories in the UK local elections. It also led to a right wing candidate reaching the run-off election for the post of the French president.

It also almost certainly led to Trump’s election as president of the United State. His promise to make America great again resonated with those who saw their jobs sliding into an abyss as a seeming flood of strangers entered the country. In the US case of course the unwanted immigrants came mostly from Mexico.

While the United States has its problems, I doubt that Trump can solve them by banning and deporting all the illegal immigrants in the country, which would remove many hard working and useful people, and declaring that the mining industry would be revived and that people would get their jobs back.

This goes against all economic common sense as the solid fuel mining industry is in decline in most parts of the world, and any gains will be short term and will rapidly fade away, leaving the miners in a worse position than before. It’s hard to see how any of Trump’s actions and reforms will turn the country around.
