The dark matter problem is one of the most fundamental and profoundly difficult to solve problems in the history of science. Not knowing what makes up most of the known universe goes to the heart of our understanding of the Universe and our place in it. In Search of Dark Matter is the story of the emergence of the dark matter problem, from the initial erroneous ‘discovery’ of dark matter by Jan Oort to contemporary explanations for the nature of dark matter and its role in the origin and evolution of the Universe.........

Martin Gardner can be considered one of the best there ever was in writing about mathematics. His essays are always entertaining and contain enough content to suggest other applications of the main point of his thesis. This book contains a series of short puzzles, most of which have quick solutions based on an "alternate" form of reasoning. That form is described as an "Aha" moment, where looking at the problem a different way leads to a simple solution to what appears to be a hard problem.

Delivered by Mark Steel, each scripted lecture presents persuasive, yet witty, arguments for a seemingly bizarre solution to a contemporary social problem by highlighting the flaws in the present system.

W. E. B. DuBois wrote in 1903 that `the problem of the twentieth century is the problem of the colour line - the relation of the darker to the lighter races in the various areas of the world in which they interact'. As the century draws to its close, this remains true; if anything the salience of race and racism in all its manifestations has grown in the recent past. The last few years have witnessed a growth in academic interest in racism, and in related issues such as nationalism and ethnicity. . .
