American Scientist

In ordinary times any American scientist would deem it a distinguished honour to be nominated as the Pilgrim Trust lecturer. In these extraordinary times the significance of this lectureship is enhanced by the fact that American and British scientists are working hand in hand, not only to advance science as an important aspect of man’s culture, but now especially as a powerful tool for the preservation of our opportunities for continued life, liberty and pursuit of happiness. Consequently, when Sir Henry Tizard transmitted your invitation for me to deliver this lecture I accepted the invitation with profound appreciation and humility. There were also two personal aspects of this invitation which aroused in me a sentimental reaction. The establishment of the Pilgrim Trust lectures was announced to the Royal Society by your late colleague, Sir William Bragg, in his presidential address at the anniversary meeting of the Society in 1937. Not only has Sir William Bragg, together with his distinguished son, been an inspiration to my generation of American physicists, but it happens that he delivered the address at the Graduation Exercises of the Massachusetts Institute of Technology on the occasion of my inauguration as president of that institution in 1930. I recall very vividly his remarks on that occasion and my feeling that his presence was an inspiration to me at that time when, with considerable trepidation and regret, I moved from the research laboratory into an administrative office.

Abstract For an unbalanced rotor, amplitudes of vibration are given for different rates of constant angular acceleration and deceleration. The setup used to obtain these results on the differential analyzer at the Massachusetts Institute of Technology is described briefly and shown diagrammatically. The selection of spring constant, damping, and mass of suspended unit as a means of avoiding serious vibration in bringing a heavily unbalanced spring-mounted rotor up to speed is discussed in connection with the results.

This paper highlights various aspects in the development of nanoscale armors for soldiers. Founded at the Massachusetts Institute of Technology in 2002, Institute for Soldier Nanotechnologies (ISN) is dedicated to achieving such objectives through nanotechnology. Paula T. Hammond, an associate professor of chemical engineering at the institute, leads a research team that hopes to discover materials that can both detect and resist chemical weapons or biological attacks. The difficulty in using multiple polymers—and other materials—has long been that polymers tend to separate from each other. Hammond's solution is a novel use of polyelectrolytes. Eventually, molecules in a soldier's uniform will be able to neutralize specific chemicals and literally pop the cells of less-than-friendly biological agents. Hammond plans to also include a layer of nano-size molecules called dendrimers, which can react with mustard gas and deactivate it. Many of the coatings they have come up with have the added benefit of being waterproof-protecting soldiers from the elements as well as from things like E. coli.
