Marienplatz and the Deutsches Museum

2008 Dec 19, 12:18

Church Tower in MarienplatzOn Monday in Germany we went to Marienplatz and wandered around the Christmas Market, some of the stores, had drinks in a little pub, visited the Toy Museum, and checked out an impressive looking church. We accidentally drew in some other tourists as we stood gaping at the Glockenspiel tower waiting for the little show to begin at the wrong hour. That night Megan and Oliver came by our hotel and took us out to a traditional Bavarian restaurant and brewery that had been brewing beer there for hundreds of years. It was fun although we may have kept Megan and Oliver out too late on a weeknight.

Deutsches MuseumThe next day we went to the Deutsches Museum the largest science and technology museum in the world. And indeed it is very large, six floors on a large grounds. I needed to better pace myself: I spent too much energy being interested in the engineering sections with steam engines, mining, aerospace etc. I was completely worn out by the time we got to physics, chemistry, etc. etc. and we didn't even look in the natural sciences section. Anyway, its very large. That night we ate with Jon at an Italian restaurant. During the meal two period dressed children came in and began singing then tried to shake down their captive audience in the restaurant asking for money. The man at the table next to us asked one of the children what charity the money was going towards, the child said they kept the money, and the man said never mind then and sent the child away.

2008 Oct 10, 1:32Xkcd providing answers to questions that I forgot I had, like what is the answer to the lawn-sprinkler question from Surely You're Joking Mr. Feynman. "Feynman used to tell a story about a simple lawn-sprinkler physics problem. The nifty thing about the problem was that the answer was immediately obvious, but to some people it was immediately obvious one way and to some it was immediately obvious the other. (For the record, the answer to Feynman problem, which he never tells you in his book, was that the sprinkler doesn't move at all. Moreover, he only brought it up to start an argument to act as a diversion while he seduced your mother in the other room.)"PermalinkCommentshumor feynman comic blog xkcd physics science math

Patenting reincarnation - Knowledge Jolt with Jack

2008 Aug 28, 10:58"The patent is really bad, which is all part of the fun: Abstract: The invention consists of the process of reincarnation or rebirth resulting in immortality. Description: [0001] This invention resulted from my combining Einstein's Theory of Relativity and Newton's Second Law of Physics. [0002] Reincarnation is defined in Webster's Third New Inernational Dictionary as "rebith". Thus my invention is a process of rebirth or in other words immortality."PermalinkCommentshumor patent via:kris.kowal reincarnation
