text: In the summer of 2006 two books attacking string theory, a prominent theory in physics, appeared: Peter Woit&apos;&apos;s &apos;&apos;Not Even Wrong&apos;&apos; and Lee Smolin&apos;&apos;s &apos;&apos;The Trouble with Physics&apos;&apos;. A fierce public debate, much of it on weblogs, ensued.Gina is very curious about science blogs. Can they be useful for learning about or discussing science? What happens in these blogs and who participates in them? Gina is eager to learn the issues and to form her own opinion about the string theory controversy. She is equipped with some academic background, including in mathematics, and has some familiarity with academic life. Her knowledge of physics is derived mainly from popular accounts. Gina likes to debate and to argue. She is fascinated by questions about rationality and philosophy, and was exposed to various other scientific controversies in the past.This book uses the blog debate on string theory to discuss blogs, science, and mathematics. Meandering over various topics from children&apos;&apos;s dyscalculia to Chomskian linguistics, the reader may get some sense of the chaotic and often confusing scientific experience. The book tries to show the immense difficulty involved in getting the factual matters right, and interpreting fragmented and partial information.
  Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished.This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth&apos;&apos;s geological history.
  An &#40;e,2e&#41; experiment is the measurement of an electron impact ionization process where both the exiting electrons are detected in coincidence. Such measurements are almost at the limit of what can be known, in quantum mechanical terms, and its description presents a substantial theoretical challenge. There are at least two very good reasons for studying &#40;e,2e&#41; and related processes. In the first place we are now only beginning to understand the dynamics of the collision process. The range and sophistication of present experiments allow us to identify kinematic regimes where delicate and subtle effects can be observed, stretching current theories to their limit. Secondly, the multiple coincident technique offers us the possibility of an analytical tool that could be used to probe the structure of the target, be it atom, molecule, thin film or surface. Measurements are now being performed at threshold on H, on the inner shell levels of Au and Ag using projectiles at relativistic energies, with spin-polarized electrons on Li, on a myriad of molecules in symmetric, noncoplanar kinematics, and on He in a multitude of different geometries. The technique has recently been extended to excitation ionization &#40;e,3e&#41; and &#40;gamma,2e&#41; experiments. Major theoretical advances have also been made, but much still remains to be done.This volume contains the invited papers that were presented at the Workshop on &#40;e,2e&#41; and related processes which took place in September/October 1992 in Cambridge, UK. The three major review papers which it contains together form an excellent introduction to this new and rapidly expanding area of physics and set the scene for the wide range of research contributions, both experimental and theoretical, from the leading scientists in the field.
