Adults - Periodic Shirt
$27.95
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.
Einstein's Telescope
$29.95
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.Information
