Today was my big teacher-training examination, consisting of two lessons (one math, one physics) and an oral exam. I passed, so I can now officially call myself a teacher!
However, that doesn’t mean that my teacher training is over now. It will end on January 31st, 2004, and now I’m looking for a job, preferably starting on February 1st…
… but first things first. I didn’t get much sleep during the last two or three weeks, so that’s very high on my priority list right now. And food. And maybe a good movie. I allowed myself a free evening last week to watch The Two Towers on DVD last week, but I haven’t seen any of the additional material yet.
Photos taken today between 19:00 and 19:30 MEZ near Bonn. I didn’t have time to reduce the noise properly, but you get the idea. If the sky is clear where you live, I recommend going out with your camera and a tripod tonight!
Und noch ein Link zu einem Junior-Hobby-Astronomen in Bad Honnef bei Bonn: Space Observer.
Link gefunden im Generalanzeiger Bonn: Selbst Wetter-Guru Kachelmann fragt um Rat
Ooh, a MetaFilter thread about Paul Erdös, the man who loved only numbers. I read My Brain is open by Bruce Schechter, but I think I’ll also have to check out The Man who Loved Only Numbers by Paul Hoffman.
Links (nicht nur) für die Schule
Thanks to Manila‘s discussion group that requires signing up and logging in, my weblog has not yet been comment-spammed. However, bad people always think of new strategies. The latest seems to be setting up a pseudo-weblog with links leading nowhere, a stolen design and hidden links to p*rn or whatever. Then they spam the referrer lists of weblogs in the hope that their Google ranking will improve.
Jeff noted the referrers and found an explanation and a link to an interesting article about the problem. idly.org: P*rn Sites Hiding Behind Blogs. And there’s also a referrer page to be indexed by search engines.
Finding matching colo(u)rs
Yet another link for the collection: Colormatch 5K. I previously linked colour scheme chooser, A recipe for color and Martin’s 6-Colormatch.
Still alive, still busy. I barely have time to spend surfing the web, but I always seem to accumulate a number of noteworthy links… I don’t think I’d know what to do with them if I didn’t have a weblog.
Today is André‘s (27+n)th birthday. Happy Birthday!
Sunrise this morning, around 7:30 am, from our living room window.
The Tertiary Phase of the Hitchhiker’s Guide to the Galaxy radio play is being produced, and a fourth part is going to follow. We have the primary and secondary phases, and I really hope the two new parts will turn out as good as these.

There will be a total lunar eclipse during the weekend. The maximum will occur on Sunday, November 9th, at 2:18 GMT+1. The moon enters the earth’s penumbra at 23:15 GMT+1 (the day before) and the inner umbra at 0:32 GMT+1. I talked about lunar eclipses in my 6th grade physics class today. It took the students a while to understand the differences between a new moon and an eclipse, which occurs at full moon. But when they finally got it, one girl asked, “But why isn’t there an eclipse every time the moon is full?” I think the question indicates that she really understood how the eclipse works. I told the students that they should ask their parents to watch at least part of the eclipse with them – I know it will be fairly late for eleven-year-olds, but it’s the weekend, they can sleep in on Sunday. I’m really looking forward to the next lesson (on Monday) to see how many of them actually stayed up and watched.
We also “built” a model of our solar system (just the sun, the earth and the moon) in class today: a marble was the earth, a pinhead represented the moon (about 10 cm away from the earth), and the sun was a swiss ball. We had to go out into the schoolyard in order to have the sun and the earth at the proper distance. I sent one girl all the way across the yard with the sun. After our little experiment was done, she quickly came back to the rest of the group. I told her she was moving faster than the light because it takes photons eight minutes to travel from the sun to the earth. I think she was quite amused by that.
Science is fun!
Archimedes’ Laboratory (site available in English, French, Italian) is a “geometric puzzle site [that] is designed for open-minded people with a fair amount of curiosity and humility. To solve the perplexing and tricky puzzles that you will find in the following pages, you need a very high IQ, not the usual and controversial Intelligence Quotient, but the ‘Inveniens Quaerendo’ (Latin, discovering by trying) ability. Intelligence is not what you feel or what you know, but a problem solving skill. ”

Note to self: After the exams, take some time to read The Physicality of Books – A Survey. A lot of authors answer these five questions: 1) What do you most like about the book as a physical object? 2) Do you have any rituals or procedures you go through after acquiring a new (or used) book? 3) Is it necessary for books to exist as physical objects in our increasingly electronic world? If so, why? 4) What recent examples stand out for you as exemplar of well-designed, well-made books? 5) Do you have any memory connected to books that you would like to share?
Es wird höchste Zeit, dass ich die Mathematischen Kleinigkeiten und die Physikalischen Kleinigkeiten mal in meine Bookmarks aufnehme. Aber der Blogtracker zickt seit einigen Wochen ‘rum. Ob ich mal einen vernünftigen RSS-Newsreader brauche?
