A new wiki encyclopedia project—and more! We aim at reliability and quality, not just quantity. We welcome collaboration with everyone who has knowledge, broad or narrow, about any of the world's innumerable subjects. We write under our real names—and are both collegial and congenial. Our welcome page, for instance—this page—is not protected: it can be edited by any Citizen. We now have [[:Category:CZ Live|Template:Articles number+ articles]] and are gathering speed. Eduzendium participants write for academic credit. Write for the Citizendium—knowledge is fun! Sign up—we need both authors and editors (you might be both!) Then, get a quick start. Remember, we are an open, young project—it's easy to get involved! Wikipedians are very welcome! Learn about us Why Citizendium? Myths and Facts: Citizendium may be different from what you think!

Johannes Diderik van der Waals (Leiden, November 23, 1837 – Amsterdam, March 8, 1923) was a Dutch theoretical physicist. His name is primarily associated with the van der Waals equation of state that describes the behavior of gases and their condensation to the liquid phase. His name is also associated with van der Waals forces (forces between stable molecules), with van der Waals molecules (small molecular clusters bound by van der Waals forces), and with van der Waals radii (sizes of molecules). He became the first physics professor of the University of Amsterdam when it opened in 1877. Johannes Diderik was the oldest of ten children born to Jacobus van der Waals and Elisabeth van den Berg. His father was a carpenter in the Dutch city of Leiden. As was usual for working class children in the 19th century, he did not go to the kind of secondary school that would have given him the right to enter university. Instead he went to a school of "advanced primary education", which he finished at the age of fifteen. He then became a teacher's apprentice in an elementary school. Between 1856 and 1861 he followed courses and gained the necessary qualifications to become a primary school teacher and head teacher.[more...] New Draft of the Week [ about ] John Brock is a fictional British undercover agent created by Desmond Skirrow. He appeared in three fast-paced, witty, and irreverent spy novels written in the late 1960s. Like his creator, he is a successful advertising executive in London; but he is also a part-time agent coerced to work from time to time for a secret department on the Addison Road run by the fat man. Brock is tough, witty, combative, extremely competent, and supremely resilient. Even by fictional standards, he absorbs incredible amounts of physical damage at the hands of his adversaries before, after a few whiskeys and a few hours sleep, he is ready for his next fight against overwhelming odds and, quite likely, yet another beating. Cigarettes and sweet white wine At the time of his first appearance in It Won't Get You Anywhere, published in 1966, Brock is most likely in his early 40s, a large, tough, extremely strong man who had apparently served with British special forces in small boats during World War II, probably with SIS (Secret Intelligence Service} or SOE (Special Operations Executive).[more...]
