Happy Pi Day! Today, NASA released this awesome photo of a NASA-themed pie with NASA's Pleiades supercomputer at Moffett Field, near Mountain View, California. Fun fact: in 2011, researchers calculated the sixty-trillionth binary digit of Pi-squared. The work behind the calculation was based on a mathematical formula discovered more than a decade ago by David H. Bailey, the Energy Department's Chief Technologist of the Computational Research Department at Berkeley National Lab. <a href="http://energy.gov/articles/supercomputers-crack-sixty-trillionth-binary…; target="_blank">Learn more about their calculations here</a>.
