Physics

It’s Einstein‘s birthday today. He was born 123 years ago. A few interesting Einstein links:

Fun with Mathematics

Is your date of birth in π? Okay, most people’s date of birth is, but it’s still fun to play around with the queries on the site.

Reading

Booklend seems almost too god to be true: It’s sort of an online library. Booklend will send the books to your doorstep and even provide an envelope for free return. You can keep the books as long as you like. Cool idea, and people seem to actually return the books they borrow.

Spring?

Can you believe it was snowing today? In Bonn it was just raining, but 30 km and a few dozen metres of height seem to make all the difference, as it was snowing heavily in the town where my school is. And here I was thinking that spring had arrived because all the cafés in the little town had put their tables and chairs on the sidewalks. This morning, chairs and tables and the little flowerpots on top of them were covered with a few centimetres of snow.

It’s a good thing that I go to school by train; I’d really be worrying about getting to school by car tomorrow because I just heard on the radio that it still is snowing heavily in the Eifel.
