Quiz

Darn it if it isn't time for a new quiz! It was a lot of fun last time don't you think???
Are you with me? (if enough people say yes I will start to think of questions)

Theory

One of my theories (I have many as you might be aware) is that 'the vet on bondi beach' gets to score more than any man alive. 

Showers

Is there anyone else who has noticed that if you increase the temperature in the shower while you are in it there is a spike in the temperature that lasts only parts of a second before it evens out at the new setting. I think of this quite a bit and am rather convinced that it is a real phenomena and not an imaginary one, but I need a fast IR thermometer to confirm, which I do not have. The only explanation that I have is that when you turn the dial a turbulence is created that momentarily disturbs the flow and for a moment sends more hot water than it should down the hose. Why the spike always are hot I have no explanation for.

And while we are at it, have you noticed that while taking a shower at a communal shower (like at the gym/training hall) where you push a button and get a random period of shower time, that while you are in the shower that period is very short and you have to press the button over and over again to get the soap out of your eyes, but when you are finished and get out of the shower the water just keeps coming. How the hell does the shower know that I have soap in my eyes?

I forgot the laws of physics

I used the mailman vest yesterday when delivering mail in the snow. It is like a BabyBjörn but instead of a kid you have bundles of mail on your chest. The bundles are held together by rubber bands which I take off and put on the stiff plastic back of the vest when I start on a new bundle. As I said, yesterday it was snowing, and when I came back to the office most of me was soaked and hence I put most of my clothes in the drying cabinet, put said cabinet on 70°C and then went and had lunch. This is where the laws of physics come in. Most materials expand when they get hot, but some does quite the opposite. Rubber is one example. When rubber gets hot, the carbon chains that it is made of start to vibrate more vigorously and when they do they contract. As you have guessed by now, the rubber bands that I had put on the vest got quite a bit smaller in the heat and totally warped the stiff plastic back... So, there you have it, proof that knowledge of physics can be useful even for a mailman, sort of.
