I came across one of those pages on the Internet which state something like “At least a few molecules of the water in your body probably passed through the kidneys of Julius Caesar“. They generally use statistics to show that what they are saying is true.

Only those who believe in homeopathy should be disturbed by this. To anyone else, a molecule of water is a molecule of water, and the fact that it had once been contained in a stream of urine is irrelevant. In any case it is too late. 60% of our body is made up of water, so water from Caesar’s urine is already in us.

Water is a fascinating chemical. It carries stuff around as it is the basis for blood and lymph and all the other fluids of our bodies. It carries nutrients up the stems of plants. It wears away mountains and builds rocks, it cools lava to form other rocks. It brings nutrients to our crops and washes them away. It even sinks ships.

“You are water
I’m water
we’re all water in different containers
that’s why it’s so easy to meet
someday we’ll evaporate together.”
― Yoko Ono

It’s difficult to think of any occurrence in our familiar world which is not mediated or affected by water in some way. Shortage of water to a society is a disaster, as food cannot be produced, leading to famine and deaths.

Water is thought by most people to be liquid at usual temperatures, though there are some places where it is to be found in solid form. Actually there is a great deal of it around in the gaseous phase, or vapour. We measure this airborne water in terms of the humidity or wetness of the air.

Water is extraordinarily pervasive and can be found in all the nooks and crannies in the materials that we have around us. It acts as a lubricate, and if the water is driven off, by heating or chemical means things become stiff and fragile. Even so, water cannot be completely removed from things – even a diamond probably has a few entrapped water molecules.

Water plays a role in rotting things down. A corpse kept in a very dry environment desiccates and turns leathery and fragile. I guess that this is because the organisms that rot a body away cannot function in a water free environment.

A body of liquid water fills things from the bottom up. Gravity pulls the water down to the lowest parts of a container and water continues to layer the container. The surface appears to be flat, but that is an illusion. At a small scale, if a tiny bit of the water happens to be higher than the rest of the water, gravity will pull it down, while the other water molecules resist by being in the way.

Eventually as the water stills, the differences in level even out, and the water surface becomes as level as it can. However, at the molecular level, molecules of water, which are moving relatively fast on these scales, can pop out of the liquid and float away. Other molecules can also pop in to the liquid, so that on average the water is level.

Why doesn’t the surface appear blurry and ill defined then? Well we can’t see at the molecular scale, and also the water molecules form weak electrical bonds with each other. A water droplet is like a large crowd of people all milling about, holding hands much of the time. Those on the outside are not as tightly bound as those further in.

Imagine now that the crowd is surrounded by a storm of people who are moving faster, and are more spread out so they rarely join hands. One of these gaseous people will now and then bump into the crowd. They may knock loose one of the crowd who will shoot off and become one of the gaseous people, while gaseous person who hit him may now be travelling more slowly and link up with the crowd.

Even in the macro world a water surface is rarely really flat. The dynamic nature of the flatness is apparent when a container is jolted slightly and tiny waves form on the surface as compression waves disturb it. Wind and rain also cause visible disturbances in a lake or pond.

Flowing water often forms a smooth, if not level surface. A submerged rock in a river or a weir or fall in a river can form persistent ripples of flumes as the water flows over them. Kayakers know to aim their craft at a flume to safely descend a rapid or waterfall, although downstream of flumes the river often forms “haystacks” where turbulent water is forced into humps which can prove difficult to navigate.

A little stream may be described as turbulent as it makes its way over and around boulders and small drops, but interestingly it is not random. It is not chaotic. A close look will reveal that the bow waves of stones in the flow may flutter and throw off little whirling vortexes, but the bow wave and the pattern of vortexes persists. The little waterfall over a small stone ledge persists, even though the shape of the waterfall may ripple a little.

In large bodies of water, such as lakes and seas, winds form waves which can travel many thousands of kilometres across oceans and seas. Water waves don’t represent the movement of water over those distances – the only thing that moves is the energy in the wave. Water molecules in a wave move mainly up and down and only a little forwards and backwards.

However when a wave travels over a beach or shoal, the movement in the vertical direction is curtailed, and the energy is transformed into a forward motion – the wave breaks. Water is transported forward, with the water higher up moving faster than the water at the sea bed which may be water draining off the beach from the previous wave and the wave steepens until it collapses. Hence surfing!

Holidays

I should imagine that going on holiday, for many people would be a relatively new thing. While those with money might decide to shift operations from home to another location, which might or might not be near a beach, those who work from them would mostly have no respite from day to day toil, since their employers would still require looking after as usual.

As ordinary people became wealthy, and the old social structures faded away for the most part, it would have become more usual for ordinary people to go away, just as their employers used to.

The word “holiday” itself is a  contraction of “holy day”, and on holy days there were celebrations and less formal work. The word has come to mean a day on which one does not have to work. Most countries these days would have statutory holidays on which which people would not have to work. There may be other restrictions, such as legislation that shops should remain closed.

It’s understandable that some countries require shop closures, as this means that shop staff get the holiday too, but many countries these days allow shops to stay open if they wish and some of the best retail days are on statutory holidays. Usually shops that stay open are required to compensate staff who are required to work.

Holidays are disruptions to normal schedules. When one goes away, one is in a different environment and one has to make do. Even something as simple as making a cup of tea may be complicated by the need to find a spoon, a cup, and a teabag, not to mention the need to figure out the operation of a different jug!

These things are not an enormous issue, and in fact draw attention to the fact that one is on holiday. All schedules are voided and one can do whatever one wants. Often this may amount to doing nothing.

A “holiday industry” has evolved, which provides accommodation, and resources for those temporarily away from home. It also provides entertainments or “attractions” if the holiday maker doesn’t just want to lay on the beach. The holiday maker may do all sorts of things that he or she doesn’t usually do, from the exciting (bungy jumping or similar) to the restful (a gentle walk around gardens or maybe a castle visit or may a zoo).

These facilities are all staffed by helpful people who arrange things so that the holiday maker can enjoy his or her self without worries. These people are of course employed by the facilities, but many of them enjoy their work very much anyway. It’s a sort of bonus for helping people.

Holiday makers must also be fed, and this has become a huge industry too. In any seaside towns so-called fast food outlets can be found in abundance, along with more up market restaurants and cafés, for more leisurely eating. For many people one of the advantages of being on holiday is that one doesn’t have to cook, and one can choose to eat things that one doesn’t normally eat.

Holidays can be expensive. Since we are close to the Pacific Islands, like Tonga, Samoa and Fiji, many people fly out to the islands on their summer holidays. This means flight and accommodation has to be booked and paid for.

When the holiday makers arrive at their destinations, they have to pay for food and entertainment. Other expenses may be for sun screen cream, snacks, tours, tips, and the odd item of clothing which may have been accidentally left at home.

Holiday entertainment may comprise guided tours, or visiting monuments or zoos. Amusement parks are often an attraction as are aquariums. All this can cost a lot, but unless you are content to veg out on the beach, you’ll have to pay for it. Even vegging out on the beach comes at a cost, from sun protection through to drink to offset the dehydration caused by the sun.

So, why do we throw over the usual daily regime, and drag our family on an often uncomfortable road, sea, or plane trip, to a location where we know little of the environment, which will cost us money, to spend the days traipsing from “attraction” to “attraction” spending more money and feeding on often costly food of unknown quality or provenance?

Part of the answer is that the daily regime becomes boring and descends into drudgery. Removing ourselves from the daily regime allows us to escape that drudgery for a while. As far as the cost goes, well, one is prepared to spend a certain amount of money to escape the drudgery for a while.

Removing ourselves from the usual means that we can try the unusual. We may try Mexican food, or Vietnamese food. Or even Scottish cuisine if we choose. The world is our oyster.

We can try sports and pastimes that we have never tried before. Bungee jumping. Skiing, water or snow. We can visit a “Theme Park”, ride a roller coaster, or other ride. We can scare ourselves and excite ourselves.

We can experience different cultures, different scenery, but at the end of the day we know that we will be returning to our mundane lives. We have at the back of our minds the cosy ordinariness of our usual lives, as a sort of safety harness.

We know our comfortable house will be there for us to return to, and while we may enjoy the beds in our hotel, motel, holiday home or tent, we look forward to the return to our own beds. We look forward to drinking the brands of coffee and tea that we prefer and fill the fridge with the foods that we prefer to cook.

Few people would want to live in hotels and sleep in strange beds as a way of life, but there are some people who do so. While we enjoy being on holiday, as a break from our usual lives, we would probably not want to live that way for an extended period. Those who do are unusual people.
