- A very nice article about Go and the software that plays it. (I’ve never played Go, but the fact the board must tend toward a fractal distribution of pieces is the one thing that’s obvious from a crude description of the rules.)
- A panel discussion about quantum mechanics in which three guests articulate their ideas very clearly and the fourth spouts complete gibberish.
- H.G. Wells also wrote non-fiction about Martians.
- Article on how the moon and its distinctive hemispheres came to be. [Update: here’s another idea.]
- Catfish detects breath of prey via acidity of water.
- Dust on Mars rovers.
- Proof that Ancient Greeks had computers.
- Distribution of letters in different parts of words. What ways can you come up with to play with the data? For example, pairing letters with similar profiles, I get a=o, b=w, c=p, d=y, e=l, f=k, g=s, h=i, j=q, m=t, n=r, u=v, x=z. (Some pairs — especially x=z — are only similar in the sense that they are both miscellaneous.)
- Delightful puppet video. Don’t over-analyse the plot; it’s all about the aesthetic experience.
