Four years ago

Only when I flipped the page did I realize that today is September 11th, four years after the terrorist attacs on the World Trade Center and the Pentagon.

Photos from the past

Germany in 1929 is a gallery of black and white photos of towns and landscapes in Germany. The pictures are interesting to see just by themselves, but if you know how some of these places look like now, it’s even more intriguing.

Someone posted twenty photos of Germany by the end of or shortly after World War II on flickr. He wasn’t able to identify all the places, but quite a few of them were taken in the area where we live, e. g. Cologne, Remagen, Frankfurt (Main)… The comments are worth reading as well.

Lots of old stuff

Okay, in an attempt to clean up my hotchpotch of links, here are lots of different things, some fun, some instructional, some crazy, some yummy…

Cooking and Recipes

Everything You Always Wanted To Know About Sleep (But Were Too Afraid To Ask). Explains why I always stay up late (like today) and feel tired in the mornings – and by the way, it also states that adolescents are “night owls”, probably because of hormones, so school should probably start later than it does to accommodate this.

… for school

Optical illusions

If you read a handful of weblogs, you will probably have seen these optical illusions before in the past months, but I’m including the links so I can find them again: rapid afterimage, almond illusion.


Classic Cat “is a directory with links to over 3000 free to download classical performances on the internet, sorted by composer and work. To find the classical music you select a composer, a work and a performing musician. Then you are transported to the page of the musician(s) where the music is hosted and you can download it.”
