The total entropy of any isolated thermodynamic system tends to increase over time, approaching a maximum value.

This is a rather depression fundamental truth when extended to its final most absolute conclusion. But for at least the next 6 Billion years or so we don’t have to worry about that fact and therefor actually have much more pressing issues to worry about. But today I wanted to talk about the little localized anomalies to this generalized law otherwise known as human children and how they contribute to a massive increase in entropy through an amazing expenditure of energy.

One definition of entropy is a measure of the disorder and chaos of a system. Energy must be exerted in order for a system to obtain and maintain uniformity and order. Classic examples are a perfectly ordered deck of cards or an ice cube. The chances a shuffled deck of cards that is thrown on the floor and then randomly picked up being in perfect order is much closer to the chance that all the water molecules in my glass will suddenly arranging into the exact formation of ice at room temperature than the chance I’ll get a royal flush. In order to get that perfectly ordered deck or ice cube at room temperature energy must be used because those states are not naturally spontaneous. This means that the deck of cards and ice cube have lower entropy than the puddle of water and shuffled deck.

So what does this have to do with kids. First they are an example of a very low entropy system. What are the chances that the same amount of carbon, hydrogen, nitrogen, oxygen, phosphorous, trace metals and other elements that make up a 3 year old randomly combine in just that way to make that unique and precious human being. So astronomically small that if you measure the economic value of all the complex proteins, intricately made cells, and everything else your DNA codes for and produces you could be worth $47 million, on the other hand if you just count just the basic elements and not the amazing way your body has arranged and uses them then your worth about $5. Second kids, and sometimes humanity as a whole though the final jury is still out on that one, tend to expend large amounts of energy not to create order but to create disorder and wreck havoc.

Now for the example from this weekend that provoked this whole train of thought. From somewhere a few of the kids on my street had scavenged the pieces to make a small push go-cart (I hear you saying Trevor, that’s a perfect example of human ingenuity being used to decrease entropy – please bare with me). The main core of the cart was an old discarded push lawnmower. The back axle on this lawnmower had worn through the plastic body and was falling out. I helped the kids fix it by basically sewing the axle in place with metal wire and pushed the kids around for a while. I took several pictures of the fixed axle and the kids playing with the cart.

The next day when I got back from work I found the cart completely demolished. One day of intense play was all it took. Granted the warranty on this car covered maybe its first 2 minuets of use and it wasn’t meant to last forever, but I figured it had more than a day in it. However, think of all it must have seen in its short existence as a children’s entertainment, and surly it was better than all the Teletuby episodes combined. It probable traveled the length of the street hundreds of times during the day. It was fought over, crashed into, sat on, jumped on, jumped over, pushed, pulled and enjoyed by at least 15 kids on the street. The back wheels probably feel of multiple times before it became impossible to hack them back on and then it was probably used more as a sled than a cart for a while. Once that wore the front wheels off dissecting the remainder of the car became much more of a game than strategically trying to build it up again. I know all this because I was once a kid and remember having jousting matches on the sidewalk with our big plastic big wheels, taking them to pieces in the process when I was 8. Here are some pictures of what the cart looks like now.

If you divide up a systems energy into that which does work, useful energy, and that which goes to wast, useless energy – in the context of productivity, advancement and the capitalist dream or just the elusive perpetual motion machine, than one interpretation of entropy is the useless energy. But think how much energy those 15 or so kids used up throughout the course of the day as they slowly and enjoyably destroyed their cart through natural play. Their play most definitely increased the overall entropy of the situation so what if any useful work did all that energy do. I believe it went into molding and shaping their mind and character. Through the course of a days playing they learned a few important lessons, might understand social interactions a little better, saw the value in having a cool play toy and learned what its like when that toy no longer works. Because of this one day they may grow up to be loving, carrying, socially engaged adult citizens. Who can actually judge the true value and worth of child’s play.

Now for a total change of subject on our current theme. As many of you may know my bike was plagued with a terrible case of increasing entropy. At last count the breaks didn’t work, it had no peddles, the gears wouldn’t shift into low gear with out me kicking the shifter while riding, the chain fell off frequently in high gear, and it was to small for me. I’m quite happy to report that I bought a new bike on Sunday. My host uncle owns a truck and took me to the mall in Nelspruit and the bike shop. The guy in the store tried to sell me a really nice bike with disk breaking, locking rear and front shocks and a host of other pretty nice things that also happened to be way out of my price range. I talked him down a few models by explaining I only needed this bike for another 17 months, wasn’t going to ride any races, and would only use the cash I had in the envelope in my backpack. Needles to say I am enjoying the new bike very much and hope to do a nice trip up the back roads in Barberton’s mountains soon. I’ll post about it when I get back, and I’ll probably tweet from the top.
