Here’s a journal I never thought I would ever be linked to: Chemie in unserer Zeit, a chemistry journal published by Wiley InterScience, uses my photograph of Antonio Stradivari’s Messiah violin to illustrate an article. The photo was released by me under the free CC-BY-SA 3.0 licence on Wikimedia Commons. It’s also nice to see that the journal takes the time to credit the photographer of an image they found online.
I am also told that the same image is used in a textbook, Chemische Köstlichkeiten (ISBN 9783527327522).
A well-known probability riddle is “I have two children. [At least] one is a boy. What is the probability I have two boys?”; the answer is 1/3.
Richard shares a variation (imagined by Gary Foshee) which I find counter-intuitive: “I have two children. One is a boy born on a Tuesday. What is the probability I have two boys?” (Assume uniformity over genders and days of the week.) This is easy to solve, using the method of your choice (1, 2).
Spoiler alert: the answer is 13/27. The addition of a seemingly useless piece of information makes a big difference, which surprised me.
