At the dawn of the twentieth century, physicists made a revolutionary discovery: elements are
	    not eternal. Atoms can fuse together to create new elements; they can also spontaneously break
	    down, firing off subatomic particles and switching from one element to another in the process (see figure, right). While
	    some physicists used these discoveries for applications ranging from nuclear weapons to nuclear
	    medicine, others applied them to understanding the natural world.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://evolution.berkeley.edu/evolibrary/article//history_23">Radioactivity also gave the history of life an absolute calendar. By measuring the atoms produced
	    by these breakdowns inside rocks, physicists were able to estimate their ages (right). And by comparing the
		ratios of those atoms to atoms from meteorites, they could estimate how long ago it was that the Earth
		formed along with the rest of the solar system. In 1956 the American geologist Clair Patterson (left)
		announced that the Earth was 4.5 billion years old.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/0AFD0BC0-A9C5-4A01-AEED-CB8036FF9342/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
