Boris Chirikov - Sputnik of Chaos

In Russian, the word Sputnik means companion. But after the very first artificial satellite Sputnik, launched back in 1957, this word became also a metaphor for a pioneering, outstanding achievement. These meanings are appropriate for a portrait of Boris Chirikov, who was the founder of the physical theory of Hamiltonian chaos and made pioneering contributions to the theory of quantum chaos. In...

We Need Another Sputnik Moment!

The need for a qualified workforce in information technology and the broader science-technology fields, referred to as STEM (Science, Technology, Engineering and Mathematics) has reached crisis proportions. Native born U.S. students are not entering the STEM fields in college in sufficient numbers to avoid an impending technology-talent shortage. University enrollments are dwindling in the STEM...

Structural studies of the Sputnik virophage.

The virophage Sputnik is a satellite virus of the giant mimivirus and is the only satellite virus reported to date whose propagation adversely affects its host virus' production. Genome sequence analysis showed that Sputnik has genes related to viruses infecting all three domains of life. Here, we report structural studies of Sputnik, which show that it is about 740 A in diameter, has a T=27 ic...

Braille in the Sighted: Teaching Tactile Reading to Sighted Adults

Blind people are known to have superior perceptual abilities in their remaining senses. Several studies suggest that these enhancements are dependent on the specific experience of blind individuals, who use those remaining senses more than sighted subjects. In line with this view, sighted subjects, when trained, are able to significantly progress in relatively simple tactile tasks. However, the...
