"The pleasure and interest of being a scientist need not be confined to those gifted people who have the ability to pursue the highly specialised studies which are necessary for those who would reach the main frontiers of scientific advance."
G. I. Taylor, one of the great physicists of the twentieth century, among the last masters of both theory and experiment.
Computers can do many things, but there are some things they can't do. They certainly can't play tennis or the violin, but those aren't the kinds of thing we're concerned with. There are computational questions, questions of the kind that we would naturally turn to a computer to help us with, that, in fact, they cannot answer (and nor, therefore, can we).
The very fetching purple and yellow packaging states that this is "the" interactive geometry software. A little optimistic, perhaps; The Geometer's Sketchpad and Cabri both have their - not insubstantial - followings. And the previous release of Cinderella gave the impression of a terribly well-featured package lacking slickness. But therein lies the value of Version 1.2: slickness.

If you have money to invest, there are a bewildering array of different kinds of financial instrument available: interest-bearing accounts, bonds, pension funds, stocks and shares, options ...
Avid readers of popular books on the laws of nature are tolerably familiar with a number of facts. They know that electricity, magnetism and the weak force between elementary particles have been unified, that Einstein's theory of special relativity arose from an attempt to reconcile Newtonian mechanics with the laws of electromagmetism, and that his later theory of general relativity had something to do with the structure of spacetime.
