Update: There's been quite a bit of pushback about the actual scientific merits of Dwyer's experiment. We've followed up with a roundup of the criticisms. Original: Aidan Dwyer did a much better job on his 7th grade science project than any of us. While on a wintertime hike in the Catskills, he noticed the branches of trees held a spiral pattern as they ascended. He wondered if that could possibly serve some purpose, looked into it, and learned about the Fibonacci sequence, which is a mathematical way of describing a spiral. Then he studied tree branches more closely and found their leaves adhered to the sequence. The tree design takes up less room than flat-panel arrays and works in spots that don't have a full southern view.
Not bad for a kid who hasn't started high school yet.
Appprendre. Cultures. Fridtjof Nansen. Fridtjof Nansen If you can look at this picture and tell me that this isn't one of the sweetest photos of a dude with a 'stache that you've ever seen, then you obviously need to learn a little something about facial hair and being awesome. This picture alone makes the guy badass, even if you didn't know the story behind it. You will be pleased to learn, no doubt, that the man behind this vicious strip of solidified testosterone is sufficiently badass to pull off a soup strainer that epically righteous. It can be no other way. Fridtjof Nansen was a tough-as-nails Norwegian psychopath with an impossible-to-spell first name and an unstoppable desire to constantly freeze his balls off and risk his life in the name of science and kickassery. In 1882, the 21 year-old Nansen went on a naval expedition to Greenland and instantly fell in love with the harsh, unyielding hellhole he discovered there.
Ah, good times. After the war, Nansen continued being awesome to the world. Links: Fram Museum Main.
