The Periodic table of the chemical elements is a Tabular method of displaying the chemical elements, first devised in 1863. The layout of the table has been refined and extended over time,as new elements have been discovered, and new theretical models have been developed to explain chemical behaviour. The current standard table contains 117 confirmed elements as of late 2006 ( while element 118 has been synthesised, element 117 has not ). This table is displayed on this t - shirt.$27.95

Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity --dark energy -- is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking -- one that may change forever our notions of where the Universe came from and where it is going.$44.95

A highly entertaining and informative introduction to our planet and the universe we live in. Have you ever wondered what dark matter is or why galaxies collide? Or why the Moon is gradually drifting away from Earth? Space is really, really big, as Douglas Adams once pointed out, and there is no better guide to it than Fred Watson, astronomer to the stars. Fred Watson has taken the many, many questions that have been asked by listeners of his popular, long-running radio shows, and answered them in Why Is Uranus Upside Down? * How can you identify the constellations? * Does the Earth wobble? * Could you dump nuclear waste into the Sun? * What makes planets round? * Where's the nearest black hole? * Are there other universes? * Can we ever know everything? This highly entertaining and informative introduction to our planet and the Universe we live in is a must-read for enquiring minds of all ages.
