When I teach the quantum chemistry part of our physical chemistry sequence, I usually carve out one or two lectures to talk with my students about some of the wonderfully puzzling aspects of quantum measurements.
In the social sciences, 1995 may turn out to be (the figures aren't available yet) the year in which as many women earned Ph.D. degrees as men did. But in the physical sciences, the ratio is still about four to one.
I've always thought that optical transforms were a great model for the determination of crystal structures using X-ray diffraction, and I've used the ICE (Institute for Chemical Education) kit for this exercise many times.
The Dewar flasks that we use for storage of cryogenic fluids such as liquid nitrogen, oxygen, and helium, and which known outside the laboratory as "thermos bottles" were invented by James Dewar, who was the first person to liquefy hydrogen, and was nearly first in the nineteenth century races to liquefy all of the other gases.
Well, the final version of the National Science Education Standards has finally arrived. If you are involved in curriculum planning for your school or district, or if you want to study the document in detail, you can buy a copy for $19.95 + 4.00 shipping from the National Academy Press, 2101 Constitution Avenue, NW, Lockbox 285, Washington DC 20055 [1-800-624-6242].
Other articles describing this result appear on pages 152 and 182 of the same issue. The Bose-Einstein Condensate was also named "Molecule of the Year" by Science in its December 22, 1995 issue.
