Charles-Jules-Henri Nicolle

sia. Nicolle's many accomplishments include the discovery that epidemic typhus is transmitted by body lice (Pediculus humanis corporis), discovery of the phenomenon of inap-parent infection, and possibly the first isolation of human influenza virus after experimental transmission. Nicolle made many other fundamental contributions to knowledge of infectious diseases. This year is the centenary o...

Colin Clifford

(In: Rosenblith, W.A. (Ed.), Sensory Communication, Wiley, New York, pp. 303–317). Based on simple behavioural experiments, Reichardt proposed an elegant computational account of motion processing by the visual system of the Chlorophanus beetle. His proposal has been simplified, elaborated and reinvented on at least one occasion but remains the most influential model of visual motion processing...

Colin Diemer

Tropical Geometry is a rapidly developing field at the interface of algebraic geometry and polyhedral combinatorics. In [14] and [42] tropical geometry was related to constructing compactifications of certain non-compact algebraic varieties. To a subvariety X of an algebraic torus there exist compactifications X with boundaries D = X\X with desirable properties, and such that the structure of D...

Henri ’ s Crystal Ball

O n April 10, 1908, at the general session of the Fourth International Congress of Mathematicians held in Rome, Gaston Darboux presented a talk by Henri Poincaré (1854–1912) entitled The Future of Mathematics (Poincaré was unfortunately unable to deliver the talk himself). The original can be found on the web at: http://gallica. bnf.fr/ark:/12148/bpt6k17083c/f934n10. capture. It is now a full c...
