The Curious Life of Robert Hooke: The Man Who Measured London

Wed, 09/01/2004 - 01:00 -- Hal Harris

Robert Hooke's name is familiar to most of us only because of "Hooke's Law", f = - kx, which describes the potential for a harmonic oscillator. I became aware of some of the other contributions of this remarkable man by reading one of Lisa Jardine's previous books, "Ingenious Pursuits", which was my pick for May, 2000.

For a long time, it has been recognized that the oceans have been absorbing the gas, and this is often viewed positively by environmentalists, because the impact on climate change would otherwise be much larger.

What would you say are the greatest scientific ideas that mankind has discovered? Most of us chemists would say that the notion that matter consists of atoms would have to be one of them, and physical chemist Peter Atkins does not disappoint us on that score. He also treads ground familiar to us when he describes entropy and energy, and evolution and DNA.

The Height Gap

Thu, 04/01/2004 - 00:00 -- Hal Harris

A widely-held misconception is that people, in general, are getting taller. Another one is that Americans are the tallest people in the world. A handful of anthropologists led by John Komlos, a professor at the University of Munich, is using the average heights of people as a unique historical and contemporary index of health and nutrition.
