Computers change our perception of what is possible and what is valuable.
It is unworthy of excellent persons to lose hours like slaves in the labor of calculation. The proliferation of mathematical software is changing the way that we use mathematics, giving us the freedom to conduct numerical experiments without the drudgery of rote calculation, and to use visualization as a powerful analytic tool. The labs use the medium of Mathematica notebooks, electronic worksheets which combine the features of a word processor, a computer algebra system, a sophisticated calcuator, and a computer graphics package. In notebooks, you can easily combine and present fully word-processed text, symbolic and numerical calculations, and graphics. Moreover, notebooks are interactive documents, in which you can perform mathematical experiments.
