The Drunkard's Walk: How Randomness Rules Our Lives

Tue, 07/01/2008 - 01:00 -- Hal Harris

George Gamow introduced me to Monte Carlo methods in a chapter of "One Two Three Infinity" (Hal's Pick of April, 2001) that I first read when I was about twelve. His vivid description and witty illustration of the path of a staggering drunk comes clearly to mind even these many decades later, and it surely inspired my research on a number of projects.

The Sky is Falling

Sun, 06/01/2008 - 01:00 -- Hal Harris

How likely is it that an asteroid or a comet of significant size will impact the earth, and what would be the consequences? It is now widely accepted that the dinosaurs were wiped out by such an event, and recent research suggests that previous estimates of the number of asteroid impacts may have been much too low.

The Ten Most Beautiful Experiments

Thu, 05/01/2008 - 01:00 -- Hal Harris

Lists of "the best" movies, books, sports stars, American Idols, etc. etc. are often intriguing and controversial. Science has its own lists, be they Nobelists or most-cited publications.

Robert Bryce is a respected commentator on the energy industry. He writes for Atlantic Monthly, the Guardian and The Nation, and he has written books about Enron and about the oil industry in Texas. In "Gusher of Lies", he confronts politicians and entrepeneurs who claim that the United States should/could become "energy independent" at any time in the forseeable future.

Present at the Future: From Evolution to Nanotechnology, Candid and Controversial Conversations on Science and Nature

Fri, 02/01/2008 - 00:00 -- Hal Harris

You know Ira Flatow as host of Science Friday on NPR. I don't often get to listen "live" because the broadcasts occur while I am (supposed to be) working, but I subscribe to the podcasts and catch up on them later from an RSS feed.

The Copernican Myths

Sun, 12/02/2007 - 01:00 -- Hal Harris

When asked by one of our students about the significance of Nicolaus Copernicus (1473-1543) and his revolutionary (pun intended) theory of the solar system, most of us would recite the folkloric tale. A brilliant astronomer, dissatisfied with the inaccuracies of Ptolemy, devised a completely new model for the solar system.
