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.

"Bad Astronomy is just plain good! Philip Plait clears up every misconception on astronomy and space you never knew you suffered from." --Stephen Maran, Author of Astronomy for Dummies and editor of The Astronomy and Astrophysics Encyclopedia. "Thank the cosmos for the bundle of star stuff named Philip Plait, who is the world's leading consumer advocate for quality science in space and on Earth. This important contribution to science will rest firmly on my reference library shelf, ready for easy access the next time an astrologer calls." --Dr. Michael Shermer, Publisher of Skeptic magazine, monthly columnist for Scientific American, and author of The Borderlands of Science.
