It goes without saying (amongst males, at least), that one can never have too many tools. Most of us probably have more screwdrivers than any other tool, both because of their utility and their high vapor pressure (like my reading glasses), and so one needs to buy more in order to make sure that one will be available when needed.
The usefulness of the Internet for commercial and industrial purposes depends on the ability of individuals and companies to communicate privately, using an intrinsically public medium.
An ideal companion to "The Universe in a Nutshell" is this article by Neil Ashby, a Professor of Physics at University of Colorado - Boulder. Hand- held GPS devices have become standard equipment for boaters, hikers, and technology junkies. It is now taken for granted that one's position on the earth can be obtained within a few seconds, accurately, and free.
I was amazed at the popularity of Hawking's "A Brief History of Time" in 1998. Not because it was not a great book, but because the average reader's background in relativity, quantum mechanics, and cosmology is limited to their discussion in Star Trek.
If the name "Simon Winchester" sounds familiar, it is probably because of his recent bestseller, "The Professor and the Madman", the history of how the Oxford English Dictionary was originally compiled. It is supposed to be very good, but I haven't had a chance to read it myself yet.
This book is not politically correct, in an era in which school science experiments have been tamed to the point that there is little possibility that the teacher will kill or maim him/herself.
Those of us who were fans of the old "Amateur Scientist" column of Scientific American will enjoy this collection of projects that look to be fun to build and to play with. These are all things that the author has invented or adapted for a Saturday Science Club for kids near his home in Guildford, UK.
Barry Commoner argues that the central "dogma" of genetic engineering, that DNA alone controls protein synthesis in a one-to-one correspondence between genes and proteins, is highly questionable.
I first wrote about the controversial thesis of this book back in January of 2000, when my "Pick" was an article about David Hockney by Lawrence Wechler in the New Yorker. With the publication of this very attractive, large-format book, you can look for yourself at the evidence that he argues shows that many of the great master painters secretly used optical devices to help produce their work.
Ice cores, bored through thousands of feet of stable glacial ice in Greenland, have proved to be our best record of global climate over more than a hundred thousand years.
