In the last century Charles Darwin quite successfully applied the concept of evolution by natural selection to living creatures. In more general terms the concept of

Our understanding of the composition of comets has improved significantly since the recent apparitions of comets Hale-Bopp (1995 01) and Hyakutake (1996 B2), the two brightest comets in the past 20 years. New information on the composition of cometary molecules and o

It is our experience from daily life (and from precise observations in the laboratory) that the presence of one object may alter the state of other objects in some well-defined ways. We call this process an “.”, and consider it one of the fundamental, primary concepts, like space, t
