Fun with Physics: The woman leading the hunt for nature's most elusive particles

Janet Conrad received the 2001 Maria Goeppert-Mayer Award for outstanding contribution to physics by a young woman. In this New Yorker story, K. C. Cole describes the lengths to which experimental physicists must go in order to detect and study the properties of neutrinos, which barely interact with any other matter.

The Measure of All Things: The Seven-Year Odyssey and Hidden Error That Transformed the World

In 1792, the French Academy of Sciences appointed two respected scientists to survey a north-south meridian from Dunkirk to Barcelona, for the purpose of determining the size (and shape) of the earth. Why is this important? Because it would establish an international basis for the meter, foundation of the metric system.

Relativity and the Global Positioning System

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.

Vacuum Bazookas, Electric Rainbow Jelly, and 27 Other Saturday Science Projects

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.

Nine Crazy Ideas in Science: A Few of Them Might Even be True

One of the goals of a course I teach in our Honors College is to provide non-science majors with the tools they need to differentiate authentic science from material that has merely been provided a "scientific" dressing. Physicist Robert Ehrlich has provided nine case studies that are ideal for this purpose. Do more guns in the hands of citizens decrease crime? Is AIDS really caused by HIV?

The Shaken-Soda Syndrome

Try this! Take two identical cans of soda (or some other beverage). Roll then down a slight incline to confirm that they roll at about the same speed. What do you think will happen if you shake up one can and roll them again? Make a prediction. Then try it. Have your students do it. Develop hypotheses and test them. This is a terrific experiment that anyone can do.
