Caltech's Vladimir Markovic, professor of mathematics, has been chosen to receive the 2012 Clay Research Award from the Clay Mathematics Institute. 

Michael Aschbacher, the Shaler Arthur Hanisch Professor of Mathematics, will share the 2012 Wolf Prize in mathematics. The award recognizes his role in classifying types of mathematical objects called finite simple groups. According to the prize citation, "His impact on the theory of finite groups is extraordinary in its breadth, depth, and beauty."

Michael Aschbacher, the Shaler Arthur Hanisch Professor of Mathematics, has been awarded the 2012 Leroy P. Steele Prize for Mathematical Exposition by the American Mathematical Society (AMS). Aschbacher, along with coauthors Richard Lyons of Rutgers University, Steve Smith of the University of Illinois at Chicago, and Ronald Solomon of Ohio State University, were recognized for a paper on the classification of certain types of groups, which are fundamental mathematical objects.

 

 

March has been a good month for Caltech mathematics. Caltech placed first in the Mathematical Association of America's William Lowell Putnam Competition, one of the premier undergraduate mathematics contests. Also this past month, Michael Aschbacher, the Shaler Arthur Hanisch Professor of Mathematics, was awarded the Rolf Schock Prize in Mathematics.

How a cell achieves the coordinated control of a number of genes at the same time, a process that's necessary for it to regulate its own behavior and development, has long puzzled scientists. Michael Elowitz, an assistant professor of biology and applied physics at the California Institute of Technology (Caltech), along with Long Cai, a postdoctoral research scholar at Caltech, and graduate student Chiraj Dalal, have discovered a surprising answer. Just as human engineers control devices ranging from dimmer switches to retrorockets using pulsed--or frequency modulated (FM)--signals, cells tune the expression of groups of genes using discrete bursts of activation.

It may be surprising that a laser beam, when shot to the moon and returned by one of the mirrors the Apollo astronauts left behind, is a couple of miles in diameter at the end of its half-million-mile round trip. This spread is mostly due to atmospheric distortions, but it nonetheless underscores the problems posed to those who wish to keep laser beams from diverging or focusing to a point as light travels through a medium.

Tom M. Apostol, professor of mathematics emeritus and the creator and project director of Project MATHEMATICS! at the California Institute of Technology, has been elected a corresponding member of the Academy of Athens.
