...sample containing Carbon 14 (perhaps from a Sumerian tomb) is dissolved in a hydrocarbon fluid in a 4-in. tube. Radiation from its unstable atoms makes the liquid give flashes of light. They are too faint for human eyes to see, but photomultiplier tubes pick them up. The whole system is immersed in liquid mercury. As a further safeguard, the counting apparatus is adjusted so that it ignores all flashes of light too weak or too strong to come from Carbon...

Named SIR (Submarine Intermediate Reactor), it will use neutrons of "intermediate" speed and molten sodium as a working fluid. It is now taking shape near Schenectady...

Hogan, formerly of the Bell Telephone Laboratories, is noted for his successful construction of the microwave gyrator, which in principle permits the simultaneous transmission and reception of a single frequency from the same antenna. Trefethen is currently doing research in the field of fluid mechanics and heat transfer in liquid metals. Since 1951 he has been Technical Aide to the Director of the National Science Foundation in Washington...
