A equals B

The whole universe is full of inequality. No two galaxies are exactly alike, no two planets are exactly alike, no two grains of sand are exactly alike, no two atoms of silicon are exactly alike. Wait a minute, is that last one correct?

Well, in one sense each atom of silicon is alike. Every silicon atom has 14 protons in its nucleus, and, usually, 14 neutrons. However it could have one or two neutrons extra if it is a stable atom, or even more if it is a radioactive atom. Alternatively it could have less neutrons and again it would be radioactive.

So two silicon atoms with the same number of neutrons in the nucleus are “equal” right? Well, of course a single atom by itself is seldom if ever found in nature, and two isolated similar atoms are very unlikely. But suppose.

An atom of silicon is said to have electron shells with 14 electrons in them. Without going into unnecessary details these electrons can be in a base (lowest) state or in an excited state. With multiple excitation levels and multiple electrons the probability of two isolated atoms of silicon with all electrons in the same excitation state is extremely low.

In practise of course, you would not find isolated atoms of silicon at all. You would find masses of silicon atoms, perhaps in a random conformation, or maybe in organised rows and columns. One of the tricks of semi-conductors is that the silicon atoms are organised into an array, with an occasional atom of another element interspersed.

This has the effect of either providing an extra electron or one fewer in parts of the array. Under certain conditions this allows the silicon atoms and the doping element to pass the extra electron, or the lack of an electron (known as a hole) along the array in an organised manner, a phenomenon known in the macroscopic world as an electric current.

So, while two atoms of silicon may in some theoretical physical and chemical sense be equal, in practice, they will be in different states, in different situations. What can be said about two silicon atoms is that fit an ideal pattern of a silicon atom, in that the nucleus of the atom has 14 protons. Some of the properties and states of the two atoms will be different.

At the very least the two atoms will be in different locations, moving with different velocities and with different amounts of energy. They can never be “equal as such. The best that you could probably say is that two atoms of the same isotope of silicon have the same number of neutrons and protons in their nuclei.

When we talk about numbers we stray into the field of mathematics, and in maths “equal” has several shades of meaning. When we say that one integer equals another integer we are essentially saying that they are the same thing. So 2 + 1 = 3 is a bit more than a simple equality and in fact that expression can be referred to as an identity.

Algebraic proofs are all about changing the left hand side of an expression or the right hand side of the expression or both and still retaining that identity between the two sides.

In the real world we use mathematics to calculate things, such a velocities, masses, energy levels, in fact anything that can be calculated. Issues arise because we cannot measure real distances and times with absolute accuracy. We measure the length of something and we know that the length that we measure is not the same as the actual length of the object that we are measuring.

Lengths are conceptually not represented by integers but by ‘real numbers’. Real numbers are represented by two strings of digits separated by a period or full stop. Both strings can be infinite in length though the both strings are usually represented as being finite in length.

If we measure a distance with a ruler or tape measure, the real distance will usually fall between two marks on the ruler or measure. So we can say that the length is, say, between 1.13 and 1.14 units of measurement. If use a micrometer we might squeeze and extra couple of decimal places, and say that the length is between 1.1324 and 1.1325. With a laser measuring tool we can estimate the length more accurately still.

You can see what is happening, I hope. The more accurately we measure a distance, the more decimal places we need. To measure something with absolute accuracy we would need an infinite number of decimal places. So when we say that the distance from A to B equals 1.345 miles, we are not being exact, but are approximating to the level of accuracy that we need. Hence A is not really equal to B.

A particularly interesting case of A not being equal to B is in the mathematical case where one is trying to determine the roots of an equation. There are various method of doing this and there is a class of methods which can be designated as iterative.

One first makes a guess as to the correct value, puts that into the equation which generates a new value which is, if the iterative method chosen is appropriate, closer to the correct value. This process is repeated getting ever closer to the correct answer.

Of course this process never finishes, so we specify some rule to terminate the process, possibly some number of decimal places, at which to stop. More technically this is called a limit.

To prove convergence, in other words to prove that the process will generate the root if the process is taken to infinity, has proved mathematically difficult. I’m not going to attempt the proof here, but after several attempts from the time of Isaac Newton, this was achieved last century, with the introduction of the concept of limits.

One can then say, roughly, that the end result of an infinite sequence of steps in a process (A) is equal to a required value (B), even though the result no particular step is actually equal to B. You have to creep up on it, as it were.

I’ll briefly mention equality in computer programs and social equality/inequality, if only to say that I might come back to those topics some time.

Father’s Day

(I’m going to try writing this post from my Android tablet. It should be interesting!)

Father’s Day is a day of celebration of fatherhood, obviously! It’s of recent origin Wikipedia tells me, introduced in the early 1900s to complement Mother’s Day.

Mother's Day cake

As an aside, I looked up Mother’s Day and found that I was wrong in thinking that it was related to Mothering Sunday (a Christian holiday celebrating women and originally the Mother Church) or to the Christian rite of the Churching of Women (which was a blessing of those who had given birth).

c. 1470

In fact Mother’s Day was introduced also in the early 1900s to celebrate mothers independently of the religious events that I mentioned.

Both events, while they initially included church links and sermons were quickly secularised and even commercialised.

English: Mother's Day card

In particular, commercial suppliers of items which were associated with fathers, such as smoking pipe retailers and tobacconists, jumped on the bandwagon.

(From this point I am going to revert to using the PC. While using the tablet is possible, it is not as easy as doing it on the PC. One big loss on the tablet is the word count, so I can’t see how I’m going!)

Also, greeting card companies joined in in a big way. Special Father’s Day (and Mother’s Day) cards are created and snapped up by eager consumers. There are TV and press adverts not to mention and even adverts on the latest communication channels, web sites including Twitter and Facebook.

While many may abhor this “crass commercialisation” of Father’s Day (along with the “crass commercialisation” of Valentines Day, Christmas Day, Easter, and so on and on), having a special day for fathers does serve to direct the attention of offspring, who may be thousands of kilometres away, to their father and their unique bond with him.

English: James M Masters as a baby in his fath...

It may be that the child doesn’t particularly want to remember the father, perhaps because an unhappy relationship between them, but in most cases I’d expect that the children enjoy strengthening the bonds with their father.

These days, with the decline of smoking as a pastime the commercialisation of the day is mostly, it seems, related to DIY. Power tools seem to be a favourite suggestion, and other “blokey” things like barbecues and car tools and parts. None of these would have much appeal to me!

Secularisation of holidays (the word means “holy days” after all) goes hand in hand with commercialisation. About the only Christian holiday that I can think of which has been secularised but not commercialised is the Whit Monday holiday. This is not now celebrated in the UK, having been replaced by Spring Bank Holiday.

English: Return Whit-Monday Excursion from Wes...

English: Return Whit-Monday Excursion from Weston-super-Mare at Bristol Temple Meads, with unusual locomotive View southward from No. 9 Up platform, towards Weston-super-Mare and Taunton: ex-GW London and the North – Taunton – Exeter etc. main lines. The train is at No. 7 Up platform and is probably bound for South Wales as it is – unusually – headed by a Churchward ‘4200’ 2-8-0T, No. 4283 (built 6/20). (Photo credit: Wikipedia)

Of course commercialisation of holy days and religion matters is not new. The Bible tells of Jesus throwing the money changers and suppliers of animals for sacrifice out of the temple. Parents with small children at Christmas or Easter are likely to see his point.

While there may be an element of cynicism in commercially creating a Father’s Day to balance the idea of Mother’s Day, it appears that both Mother’s Day and Father’s Day originated at about the same time. It also appears that while the Church did not originate either celebration, it gladly assisted in the celebrations.

Commercial Father’s day cards come in two main styles. They are the humorous style and the mawkish. Often a card will combine both styles. Very few Father’s Day cards could be classified as sincere, in my opinion.

This is different from the Mother’s Day cards, which often fall into the mawkish or humorous classifications, but a significant number can, in my opinion, be considered sincere.

Well, let me expand on that a little. I think that because a child is more likely to say “I love you” to his or her mother and have his or her mother respond with a hug and kisses, while a father would tend not to be as demonstrative in response to such a declaration. I don’t mean that fathers would not reciprocate, as most would, I believe. They just would not do it as enthusiastically as the mother would.

So Father’s Day cards tend to be a little more sheepish, have fewer roses and other flowers on them. They tend to the uplifting rather than the overtly affectionate. One example I have in front of me says “You taught me how to believe in myself. You showed me how to be the best person that I could be”.

Mother’s day cards, on the other tend to have slogans like “Beautiful, gentle, understanding, forgiving, my mother’s love“. However, it is only a tendency, as you will discover if you go through the 15 quotes in that link.

English: A young girl kisses a baby on the cheek.

It can probably be expected that there are also special days for siblings, parents, grand-parents and so on. These haven’t really caught on like Mother’s Day and Father’s Day, fortunately. There is a Children’s Day, but that has a slightly different focus to the others, in that it is directed at children in general, and child poverty in particular, and not directed at children in the family.

That’s possibly because children in the family are celebrated at Christmas and to a lesser extent at Easter. At least from the secular point of view Christmas is mainly about the kids. OK, the parents get to have a holiday and eat and drink more than they should, but the kids’ excitement over presents and the whole Father Christmas thing drives the celebrations.

So, when Father’s Day rolls around, you could probably guess from the above that I am somewhat of a sceptic about it. Although it is a tradition, it is a very young one, and much of the impetus in supporting it comes from commercial interests. That doesn’t stop me enjoying the Father’s Day cards and gifts from my children, and even a slightly off the mark gift from my granddaughter!

Politics is a funny game.

A very funny game. You go into it as a winner, and unless you die or quit while on top, you go out as a loser. Very often a politician will resign or declare that he/she won’t stand when it is pretty likely that he/she will not achieve re-election. If he/she should rise to become leader of the party, then he/she has the additional responsibility of winning or losing an election.

If the party fails to win, it is relatively rare that leader lasts long as leader, as there are always aspiring leaders waiting in the wings. Very often the loss of an election triggers a reshuffle that sees the leader and his closest associates losing control of the party. If the leader survives the reshuffle, he/she may fill the role of “elder statesman”.

Politics in New Zealand is going through a time of turmoil. With an election scheduled for next month the ruling party has come under intense pressure from a political commentator who has acquired some emails between high level members of the party and a blogger aligned with the party.

 

English: Groucho Marx & anonymous blogging

This issue has already caused the resignation of a minister of the ruling party, but in my opinion, this close to the election this doesn’t mean a huge amount. It does dent the aspirations of the minister in question. (A minister is the person responsible for a Ministry, which might correspond to a Department in some political systems. It’s a large self-contained portion of the public or civil service).

In previous elections, the communication between the politicians and the public was through the “media”, newspapers, TV and so on. In this election, bloggers have come to the fore, and the standards, either imposed from outside or adopted within the media business, no longer apply. Although there have always been some underhand dealings, since some media reporters will be aligned with one party rather than the other, it appears as the result of the rise of blogging as a political force, that skullduggery will be paramount in this election.

Briefly, a left wing commentator has received copies of email communications between high level members of the government and a right wing blogger. The left wing commentator has added two and two and got…. well, let’s say four and a half. He’s written it up into a book, which has sold, as I understand it, pretty well for a self-published book.

Brunswick is a stronghold of left-wing politic...

I’ve got part way through the book and what has amazed me, more than the actual information contained in the emails, is the tone of the communications. To say that they were vicious in their attacks on the opposition would be an understatement. This is shocking in communications between ministers of the Crown and a supposedly independent blogger.

Also the book states that the usual time scales for the supply of information to interested parties, media or public, were altered for the right wing blogger. In other words not only was he pre-warned that he should request information from the ministry, but the supply of information to him was, apparently, expedited again by the ministry so that he got it first.

Whatever the shenanigans surrounding the content of the emails, it is evident that the emails were obtained by hacking. This is stated by the mainstream media without qualification as if that explains everything, but really, it doesn’t. So far as I know, it has not been reported how the hacking was done. It may not even have been hacking in the technical sense – some “mole” may have simply forwarded the emails.

English: Andy

English: Andy (Photo credit: Wikipedia)

If the emails were obtained by hacking, this raises an ethical dilemma for the political commentator in question. Hacking is illegal and the emails can be considered to have been “stolen”, although it is difficult to see how electronic information can be stolen, since it is not comprised of physical things, and the original owner still has his own copy of the emails.

English:

English: (Photo credit: Wikipedia)

However that is merely a matter of definition and the concept of stealing appears to morphing to include such illegal access to information. The usage has been around for a long, long time as evidenced by the concept of the theft of someone’s ideas and the concept of “intellectual property”.

Anyway, the political commentator has in his possession stolen information. He looks at it and discovers that it can be used as evidence that the right wing blogger and others have been organising attacks on the opposition political party, and sometimes on unfavoured members of the right wing party. Should he use this stolen information to inflict damage on the right wing party or is it more ethical to ignore it? He chose to use it.

There is also a section where the right wing blogger and his associates appear to have engineering a coup in a minor political party, an ally of the right wing.

English: New Zealand National Party Cabinet mi...

More damaging than any other are the revelations that senior members of the ruling right wing party have been involved in and even encouraged these activities.

As I said above, the left wing political commentator now has a dilemma. If he publishes, then he is making public emails that the right wing blogger will have wanted to keep secret for obvious reasons. Among the information about the political goings on was personal information and correspondence of the right wing blogger. This he kept secret.

There is a place for whistle-blowers in society, to alert the wider population of misconduct and illegal activities carried out by people or organisations, but such whistle-blowers are usually insiders, people who work for the organisation, rather than outsiders, who infiltrate or otherwise spy on organisations or people.

The political commentator has to decide whether he should publish the damaging content of the emails or should he just destroy the copy that he has been sent? If he doesn’t publish then the right wing blogger and his associates can continue to perform their allegedly dubious activities. On the other hand, if the political commentator publishes the contents of the emails, it could be argued that he is behaving unethically.

It comes down to the conscience of the political commentator. Evidently he has decided that it is in the public interest that the contents of the email be brought into the open and that this outweighs the ethical considerations of receiving the stolen emails. He has decided to publish his book for the public good, and has chosen to publish shortly before the election for maximum impact.

Opponents of his point out that by publishing before the election he is not only bringing the mess to light, but he is also assisting the the left wing parties, not to mention making money on the book. It’s worth considering whether these opponents would behave any differently if the situation were reversed.

We as a race spend a lot of time on what is loosely called ‘sport’. From the ad hoc beach cricket and ‘touch’, through the more organised school age sports, through the grade sports all the way up through the local and national representative sports, both individual and team.

The individual and team sports pull in a huge number of supporters, officials, organisers and so on, so it is rare individual who has not been in some trivial or profound way involved in sports at one time or another.

Sport is obviously of great importance to the human race. I don’t know of any animal that indulges in activities that could be called sports. Of course, males of many species battle other males for dominance and control over females or territory, and their young do seem to practise for these battles, but there is no sense in which these battles are fought for pleasure. They are too serious for that!

Great Battle

The roots of sport can be found in interpersonal contests of course, like arm wrestling to see who is the strongest, or quizzes to see who has the best memory and so on, but human contests don’t usually have the serious implication of battles between animals of other species. Very often they can be cooperative contests as training exercises so that the group as a whole can perform better.

This would be very useful indeed to hunters, who as a group would be benefit from the increased accuracy with the spear or the bolos, or even the simple thrown stone.

The technology would also have benefitted from such practice contests. Each contestant would have seen how his fellow contestants had improved the technology. That’s no doubt how the woomera or atlatl came to be invented, in a contest before the hunt.

Sport can also serve as a way of defusing or sublimating a dispute between rival groups. The tests of skill replaced an actual contest, and rules of procedure were imposed on the contest, so that, mostly, no one actually got killed.

The smallest group of humans is probably the family, which has a flexible definition. It could be as few as two people or as many as twenty. The concept of the nuclear family, mum, dad, kids is fairly new, inspired by cheap or affordable housing, and the ubiquity of affordable transport.

Anyway, whatever the size the family team ‘competes’ usually in a more or less friendly fashion with neighbours. However neighbourhood families ally themselves in competition with other neighbourhoods to form villages, suburbs, cities and so on up to countries. Only at the highest level is there no global group, though the United Nations aspires to that title.

United Nations - New York

Sports give humans the chance to compete, and they seem to enjoy it. How else can one explain the rise of sports like snooker, card games, and contests which don’t rate the name of sport, such as beauty contests? Is car racing a sport? Obviously some people are better at these marginal sports, so is the contest the key? It seems so.

When there is no one else around humans will compete against themselves or against chance. Solitaire, a card or peg game for a single person is popular and automatically installed on most computers. It is used in cartoons to characterise a lazy or disinterested employee.

Often a person may not be particularly proficient at a sport but may still enjoy it. They may enjoy it particularly at one or two removes, as spectators.  Spectators may identify strongly with the sports person or team in which they are interested. If they come across supporters of some other person or team, they may interact adversely with them, even to the point of fighting with them.

Parents are notoriously partisan supporters, yelling support from the sideline to their offspring, often I suspect to the embarrassment of their children. Parents also tend to overestimate the abilities of their kids and tend to push them more than they should. Sport for kids should be fun, but pushing them too hard can spoil their enjoyment of sport, which is a shame.

Those who continue to enjoy their sport and become good at it can become heroes to a large number of fans. The All Blacks are almost revered in New Zealand and the national team who play the national sport can not only receive adulation but can also be paid a lot of money.

Of course if the national team fails that can lead to a sense of devastation for their followers. Failure can be losing to another team or simply not winning. Recently the New Zealand All Blacks drew with the Australian team and it was almost as if they had lost! Fortunately the All Blacks won well the next weekend, otherwise the country might have sunk into depression.

Sports stars in the most part realise that they are representatives, but the stresses on top sports people is tremendous. The All Blacks are a good example of this. One or two of the top echelon of the rugby players in New Zealand have not succeeded in withstanding that pressure and have had issues with alcohol and violence. In a lot of ways it is unfair to expect exemplary behaviour and expertise at the top level of the sport.

Nevertheless, a surprising number of top sports people do appear to be genuinely nice people. These days, the team captain, winner and loser, has a microphone stuffed under his or her nose and is expected to give an instant analysis of the game, and to their credit most appear to come up with something intelligent about the game, congratulating their opponents, win or lose.

Interestingly, after the drawn game I mentioned above, both teams were disappointed, but for slightly different reasons. The All Blacks were expected to win, and were expecting to achieve a record number of wins, and their disappointment at not winning was obvious. There was a sense of let down. The Australians, however, obviously believed that they had missed a great chance to beat the All Blacks.

Yesterday, Today, and Tomorrow

Today Is Yesterday

Today Is Yesterday (Photo credit: Wikipedia)

The Beatles sing “Yesterday, all my troubles seemed so far away, now it looks as though they’re here to stay….”. Lennon and McCartney capture the essence of our relationship with time in just a few words. The singer was happy, things happen and he is no longer happy. From the point of view of the now, he looks back on the past and reflects on the unfortunate changes, and looks forward to a future which is less appealing than it was when, in the now that he was in then, he was happy.

English: Engraving of Council of Troubles

English: Engraving of Council of Troubles (Photo credit: Wikipedia)

In Lennon and McCartney’s words is encapsulated the feeling that the past is fixed and the future only partially knowable. Also it contains the idea that things change – the singer WAS happy, at some time in the past, and is no longer happy in the now.

Actually, since the singer is reflecting on his unfortunate position in the now, the change must have happened in the past. There was some past now when the change happened. Words begin to get a little tricky at this point.

English: I-ching

English: I-ching (Photo credit: Wikipedia)

From the point of view of the current now (tricky!) it is evident that change happens, but it is also apparent that barring time travel and the consequential paradoxes, the past is not changeable. How does that happen? How can it both be true that the past is fixed and that changes have happened in the past?

(Photo credit: Wikipedia)

This issue is related to the issue of the now. Evidently every point in time is a now point. If you consider what you were thinking or doing 10 minutes ago, you will realise that you considered that point then to be the now, not the current now.

However, if you consider that the past is unchangeable,  you could consider some future now and you will realise that from that future now, the future from the current now to the future now is the past from that future now and therefore unchangeable. So it appears that the future is also unchangeable. This leads logically to a strict determinism.

A certain change happens at some time or other, a particular now. It is possible, though unlikely in my opinion that mind, either of man or animal, may affect things after all. If that is so, then for consistency the change must propagate into the future and into the past.

If space is represented by one dimension for simplicity and time is represented by another dimension, then space-time can be represented by a sheet. A change would distort the sheet a little. It would be as if a single point on the sheet moved sideways pulling the sheet with it, and in doing so neighbouring points would be moved as well, including points on time axis before and after the point where the change happened.

However as I say, I don’t think that the mind can affect things in this way. After all the state of the mind, and hence the choices that the mind makes are predetermined, so no choice can actually change anything.

There’s a saying – “Today is the tomorrow you worried about yesterday”. This phrase also encapsulates one way that we think about time. It has a tinge of inevitably about it, as it implies that tomorrow always comes whether you like it or not. It depends on the situation as to whether or not this is a hopeful saying or a statement of inevitability.

However the main idea that this saying conveys is similar to the idea that the Beatles’ quote above – tomorrow always comes, from the moment one is born until one dies.  Well, actually, tomorrow always comes, whether or not one is alive.

Both sayings have a sense of the now moving towards the future. One concept of the now is as a sort of “cursor” travelling over the time dimension from the past into the future, but I can’t see that this is a helpful analogy. Each and every instant is a now and appears to a person as the unique now when they are experiencing it.

Another problem is that a rate of flow of time (or the rate of movement of the cursor) is logically suspect. The time dimension is used to measure rates of change so to have a measure of a rate of movement in the time dimension requires a further time-like dimension to measure the rate in. It reminds me of the apocryphal scientists who commented that we all travel through time at one second per second.

Our view of time is the now, sandwiched between the behemoth of the past and the behemoth of the future. We rarely “live in the now”, but spend a lot of our time looking towards the future or reflecting on the past. Yesterday is the source of our plans and the future is the target of our plans and aspirations.

We view the past and see how things happen, then we use that knowledge to set our plans with the intent of increasing the possibility that things happen in ways that are beneficial to us. This is a form of inductive reasoning which, while it doesn’t always work, works reliably enough for us most of the time.

The past is a burden on us as we cannot change it. All our mistakes are set in the concrete of the past, as are all our successes for that matter. In the now we try to determine what happens in the future by using the lessons of the past. We want things to be better in the future, and we project all our hopes and fears on to it.

The now is a sliver of time between the monoliths of past and future, representing, if we believe in choice, a chance to improve the future for ourselves. If we are determinists, the now is an illusion that occurs in our brain that merely serves to separate the past from the future at that instant in time in our consciousness. It is not unique, like a cursor sweeping over the timeline, but is a timeless experience at every point in time.

This post may be a little late this week, as we took the grand kids to a local “wildlife park”. Which leads me not so subtly into the topic of the week.

As kids we used to go to Granny and Grandpa’s house quite frequently. I recall sleeping over at one time, and in later years my sister lived with my Granny. I recall it being fun, but that was mostly because we could poke around in their house and garden. They had a long garden with a goldfish pond, a few apple trees, a garden and a large wooden shed.

What I don’t remember is being taken out to “wildlife parks” or similar by my grand parents. In fact, I don’t remember going out with my grand parents anywhere. I’m pretty sure that we must have gone out with them, but it must have been rare and we probably only walked around the block or something.

We did use to have big family parties and I do remember my Granny being at my Uncles and Aunties’ houses during family parties. My Grandpa died fairly young so I don’t remember him at them.

It’s different with our grand kids. I don’t know if it is because we are much more active than my grand parents were or because we are able to drive them to places. Neither of my grand parents drove that I can remember.

In contrast we fairly often drive our grand kids on trips to various places, sometimes in conjunction with their parents, sometimes without.

On Sunday, their uncle (my son) and his wife decided to take my grand kids to a local “wildlife park”, called Staglands. I went along and so did my daughter, their mother. Staglands is a fair way out of town, in a beautiful picturesque valley. My daughter drove the kids there, and I drove my son and daughter-in-law.

We didn’t stop to take photos of the valley on the way there, as we travelled independently and didn’t want to keep them waiting. As it turned out, we got there first. The road is a secondary route between a major north-south valley (the Hutt Valley) and the  Coast Road.

It is a fairly quiet road, most of the time, so is a favourite road for serious cyclists, the ones with lycra suits who are not afraid of some fairly serious hills. I’ve no problem with them, but they did make it difficult on the narrow road at times.

Staglands is 17km up this road, so that part of the trip took a while, but we got there and parked, waiting for my daughter and the grand kids. They all hopped out the car and admired the guinea fowl and peacocks which roamed the car park.

I was informed that the brown peacocks were the female ones then we paid the entry fees and went in. The path bypassed the café and wound down to a couple of small lakes, with the usual wildfowl, mainly ducks, including one small survivor of a presumably larger brood.

On the way it passed a small cul-de-sac with a “cave”, Tracey’s Cave, with a constant splash into a pool of water which created interesting ripples.

We then followed the main path up to a barn where there was a fire burning in a barrel. Did I forget to mention that we bought small packets of marshmallows and sticks at the gatehouse? Ooops. Great fun was had toasting the marshmallows, something that I’ve never seen the point of, until now.

Just down from the barn was a small paddock with a number of Kune Kune pigs. These are fairly small, hairy pigs. Kune Kune are friendly and docile animals although I would not like to be in the paddock with them. The kids, Hamish, Duncan and Louise, loved feeding them out of the small packets of feed that we bought at the gatehouse.

A walk-in aviary was next, which contained Kea. These are a large alpine parrot, which in the wild are attracted to people and  their cars. Naturally people stop to see them and the Kea respond with thievery and destruction. They pinch sandwiches and pull the rubber bits from cars.

The Kea in the aviary were less exuberant than that preferring to preen out of reach, but other birds, small parrots, were friendlier and would sit on one’s hand. A passing sparrow stopped by overhead on the chicken wire roof.

Duncan on the Bridge

The stables contained horse, donkeys and small lambs and goats, all of which got a ration out of the small bags of feed. It almost seemed that these larger animals were taking the small portions simply to be friendly.

Next was a larger aviary, planted with toe toe, a large tussocky grass with plumed flower heads, much like “Pampas grass” which is well known in some other countries. Small birds, such as finches, cockatoos and budgerigars live in this aviary.

The kids all love the “swing bridge” which connects one half of the park with the half on the other side of the stream. The first area is a mock recreation of small settlement from around the 1900s, which has been used as a set for films. Up from there is a large pond with a walkway, with on one side, a wooden railway with a push cart, usually a hit with kids, but for some reason unused today. Though I did push Duncan along in it.

After the pond was a large open paddock with deer, sheep and goats. A notice on the gate mentioned that the animals in the paddock could be “quite pushy”. A quick scramble and Hamish, Duncan and I had a glorious view of the valley, only slightly spoiled by a large logged area on the opposite side of the valley.

Then it was back down to the gatehouse and the café for re-fuelling. Hamish managed a couple of large sausage rolls (a mistake – I got the order wrong, it should have only one!) and was still hungry. Duncan went for a more sophisticated hot dogs and chips, while Louise claimed to be satisfied with an ice-cream though she did help herself to he mother’s chips. Tim (my son) and Kaz (his wife) both had nachos. I had a bacon and egg panini.

Staglands is a great place for that sort of trip and we thoroughly enjoyed ourselves. It is great to be able to spend time with the grand kids, and it a shame that, for whatever reason, we didn’t get to do similar with our grand parents.

Sports by proxy

We sit in our chairs and watch sport. We watch the news. We catch up on what friends are up to on Facebook and Twitter. Very few of us actually do anything. This is both worrying and amazing.

I’ve been watching the Commonwealth Games from Glasgow in Scotland. Sitting on the sofa I see the Silver Ferns of New Zealand play England at netball in the semi-final. (I’m glad the Silver Ferns won, of course, but you can’t help feeling sorry for the English team.)

The team members are healthy, fit and professional in their attitude towards the game, and I include both teams in that assessment of course, and they take it seriously. You can see the joy on the faces of the New Zealand team and despair on the face of the English team who came so close.

Then I look at myself. I’m reasonably fit, reasonably healthy, but I’ve not dedicated my life to a sport. I possibly could have been a reasonably good runner had I pursued my inclinations at school, but there was always someone better than me. I did enjoy running for its own sake though.

So given that not everyone can be a top sports person, why do we spend so much time watching sport? We hope that our support and the fact that the sports people that we are supporting are aware of our support and that it helps them.

Hmm, I’m not so sure. When a Silver Fern player is trapped after the event by a media person, they will quite often acknowledge the support of the “people back home”. On occasion a sports person will dedicate a match to a relative who may have recently died, or to close family, wife and babies, or even the general supporter who stays up late to catch the broadcast of the event.

But I still wonder. When I have played in sport in the past,  the sheer involvement of playing the game drives out all thoughts of supporters or other spectators. The roar of the crowd is not heard, the sideline cameras are invisible and the only thing that is experienced is the game, team mates, opponents, match officials. OK so I’m extrapolating more that a little here, but I think that it is true!

I’m not saying that support does not help a team. It definitely seems to but not at a conscious level as the conscious level of the brain is fully occupied by playing the game or it should be.

Sports people who are interviewed after a game do credit the support from people “back home” and friends and families, and I believe that in a way the support does help a team play well. A visiting team is always at a disadvantage because of the home support.

Sports men and women, after a game are asked for a snap diagnosis of the game. The best will credit the supporters for helping them win, and the best losers will accept the responsibility for the loss, which is slightly unfair if you think about it, as they cannot pass any responsibility for the loss to the supporters.

It is true that the best teams attract the most fanatical supporters, but equally, fervent supporters can help to create success for a team. So what do the supporters get out of it?

Well, there are active supporters and passive supporters, by which I mean that some supporters actually go along to the game, and some watch it on television. Both types of supporter may collect “memorabilia” of the team and this can be very lucrative for the team, and possibly help to provide the team with equipment to help them succeed.

But the “memorabilia” and the support provides the supporter with a feeling of belonging or association with the team. Some supporters purchase team shirts with name and number of their favourite player, thus associating themselves with the player. I believe that this is not really an attempt to be that player, which would be delusional, but to tell the world of their association with their favourite player in a way that is instantly recognisable to another fan.

However, what televised sports give to the supporter is an idea of what it is to be a football player or a racing driver, or even a manager or a coach. Every change to a team or the support staff is avidly reported in the press or television. Supporters then take the information and discuss the pros and cons.

For the supporter, it is almost like being a coach or manager. He or she sees what it is to be a coach or a manager, at least to some extent. An avid supporter of the team may know almost about as much about the team as some people on the staff of the team, or so they would like to think.

A good manager knows this and may put out bulletins on an injured player’s recovery and coaching staff may provide limited access to training sessions. This is done to provide a rapport with the fans, so that the fans support the manager.

When the team takes the field, spectators at the ground get a feeling of participating at an event. There is a crowd noise, a sort of voiceless roar, modulated at times by team songs and cheers and groans when points or a goal are scored. I recall being at a netball match, though I can’t recall why. The crowd noise there was headachingly high-pitched.

The way to become the centre of the event is to become a player, but most people don’t have the skill to take part in sport at a high level. With the television cameras and other technology that is available today, a spectator at home can almost come to believe that they are on the field of play.

In car racing this is taken to the next level, with cameras in cars that show, pretty much, the view that the driver sees. In field and other sports slow motion replays allow the viewer to see more than even the on field officials can see. An official might have a tenth of a second of action on which to base his decision, but the slow motion replay allows the armchair supported the luxury of several seconds and several different angles from which to view the incident.

All of which give a supporter the feeling of being at the event and of being part of it. Not everyone can become David Beckham or Usain Bolt, but being a supporter can almost get you there in a way.
