Incompetnce

I had to to an exercise sheet for the first year students. As most of the exercises I found in books were either shite or wrong (or both), I tried to do some of my own. I dug out the paper of Henry Cavendish, were he determined the density of the earth with his famous torsion balance. I calculated everything with his measurements. It took about two days until I had understood what he did and ended up at a Gravitational Constant which made sense.

I made an exercise out of it. I had to simplify it a bit, because the students did not yet know the torsion pendulum. While simplifying it, I introduced a couple of errors, which went unnoticed but made the complete calculation bollocks.

I had another exercise on an hammer bouncing off the floor where I mixed up elastic and in-elastic bounces.

When doing the example solution to the problems, the one which all other tutors would read and use to correct the exercises, I made about every possible error and mis-calculated about every quantity at least twice. So it took me about 8 or 9 iterations (all sent around to all tutors) to have a solution sheet, which was nearly right (I didn't find the errors myself, btw.). I think I should quit doing my PhD, hand back my diploma and do a ritual suicide. That would be the correct outcome of this. As I have met people who are even more incompetent and got away with it, I will wait a bit, maybe I can get away with it too...

They are right!

Being a mediocre physicist sucks. You're nerdy enough that girls won't talk to you but still not nerdy enough to not bother...

Gone Beta

So, I am Beta now as well. Which means I can do colourful texts. Yehaa. Web 2.0. Much more enterprisy!

Pickert per Inhabitants

The highest density of Pickerts per inhabitants is found in the Ohrekreis. The lowest in Dresden. Interesting statistics you can get on the intarweb...

Question

Can I kill cyclists who go around in dark clothes without any lights in the dark just so or does it need to look like an accident?
