The Black Swan: The Impact of the Highly Improbable

Like Malcolm Gladwell s Tipping Point , Nassim Taleb s Black Swan threatens to become a permanent part of the lexicon. In this best-selling book, he makes the argument that evolution has prepared us to over-emphasize continuous, Gaussian relationships because they occur much more frequently than do rare but momentous, unpredictable events.

Beautiful Evidence

The first of this series of books by Edward Tufte, "The Visual Display of Quantitative Information" was the one that, in my opinion, would be of most practical use to the average scientist. That was six volumes and twenty four years ago. I would recommend the most recent one, "Beautiful Information", as a logical continuation.

The Unintended Consequences of Hyperhydration

The folly of spending more per liter to buy water than gasoline has been mentioned in Hal's Picks previously (July 2003). That article, by Michael Schermer, emphasized the waste of money that this boondoggle constitutes. In the New York Times magazine this week is another argument against the practice, and that is its impact on the environment.

The Creation: An Appeal to Save Life On Earth

One of my picks last year was the frontal attack of an atheist scientist on religion. It was Richard Dawkins' popular "The God Delusion". This month, my choice is a respectful and conciliatory appeal by entomologist E. O. Wilson for common cause between religion and science in the preservation of what is left of Eden.

An Exact Value for Avogadro's Number

The currently accepted formal definition of a mole is the number of carbon-12 atoms in exactly 12 grams of the pure substace. This is not a good operational definition, however, because it takes too long to find, purify, and count all those atoms. The best experimental value is based on x-ray diffraction experiments on silicon crystals and puts the number within 0.0000010 of 6.0221415 x 10^23.

Exploding Disk Cannons, Slimemobiles, and 32 Other Projects for Saturday Science

Neil Downie runs a Saturday science program for kids in Guildford, UK, that appears to be the most fun that anybody could have. This book is the third in a series that describes projects that he has invented for kids to build and investigate (often with the help of an adult).

The God Delusion

Unless you teach in a religiously-sponsored school, religion probably plays little role in your teaching of science. However, the "prior knowledge" of your students includes some decidedly non-scientific, religion-inspired viewpoints that ought to be taken into account.

The Rock from Mars: A Detective Story on Two Planets

If you've been reading Hal's Picks for a long time, you might remember something about this rock, ALH84001, because the publication in Science of the paper that announced evidence in a meteorite that life had once existed on Mars was my Pick back in August of 1996. The article was controversial, as you might expect.
