Technological Enlightenment in Russia

Peter the Great brought technological enlightenment to Russia. In his lifetime, two special schools for training engineers were established, the Engineering School in 1700, and the Mathematical-Navigation School in 1701. Peter the Great introduced engineering training into other institutions as well, not only into the Naval Academy, but also regimental schools and even religious colleges. (See ...

Boris Ephrussi (1901-1979)

In yeast, Ephrussi studied how mutations in the cytoplasm persisted across generations. In mice he studied the genetics of hybrids and the development of cancer. Working with George Wells Beadle [4] on the causes of different eye colors in fruit flie...

CHAPTER FOUR PROTACTINIUM Boris

Protactinium, element 91, is one of the most rare of the naturally occurring elements and may well be the most difficult of all to extract from natural sources. Protactinium is, formally, the third element of the actinide series and the first having a 5f electron. The superconducting properties of protactinium metal provide clear evidence that Pa is a true actinide element (Smith et al., 1979)....
