...Attention. The high school films Combustion and Chlorine focus narrowly on their subjects, show only a pair of hands-those of Phillips Academy (Andover) Chemistry Master Elbert Weaver -performing experiments. Explanations are amplified by animated drawings showing molecular action. Weaver's scripts are tough enough to keep students out of that double-feature daze, call for as much attention as a classroom lecture. The films present no chemical formulae and do not show a periodic table-these can be handled better by textbooks and classroom charts. The Manufacturing Chemists' Association, which commissioned the films (cost: $20,000 each...
Where Sutherland's high school films treat simple reactions and phenomena, his college productions will be attempts to show visually two of the most basic theories of physical chemistry-the concept of molecular vibration: taught by Nobel Prizewinner Linus Pauling, and famed Chemist Henry Eyring's study of reaction kinetics. The idea that such theories, normally discussed in detail in junior-year college chemistry, might be presented in films belongs to Dr. Thomas Jones of the National Science Foundation, who conceived the project as a Brussels Fair exhibit. But "the U.S. Government is very poor," Chemist Eyring observes...
...Caltech's Chemist Linus Pauling, who won a Nobel Prize for his work on molecular structure, reported that the DNA molecule has a helical (spiral-staircase) structure. Later that year, James D. Watson and Francis H.C. Crick in England went a step farther. DNA, they said, is a double helix with two spirally rising chains of linked atomic groups and a series of horizontal members, like steps, connecting the two spirals. This molecular model, deduced mostly from X-ray diffraction photos, seemed complex and unlikely, but geneticists rejoiced when they heard about it. It was just what they" needed...

...Charlie Wilson's New Look lacked forward vision. He had little if any use for the basic research that makes possible the weapons of the future. Why is the grass green and the sky blue? Why do fried potatoes turn brown? What is the molecular secret of life itself? The answers could not shoot and therefore should not be bought with defense dollars. Why would anyone want to go to the moon? An outer-space satellite could not destroy a target and should therefore have a relatively low priority. In 1957, for example, Wilson's research and development...
