This past Friday March 14th was Albert Einstein’s 135th Birthday.  The classic equation E=MC squared is part of Albert Einstein's "special theory" of relativity that was published in 1905.  Ten years later, in 1915, he published his "general theory" of relativity. Have you ever wondered what these two scientific theories are all about and why after 100 years the science community still considers them to be so incredibly important.   A scientist who just wrote a book on Einstein and his theories of relativity joins us today on our One on One Segment to explain. Also… The World Wide Web - the Internet - one of the most valuable and important information resources celebrated its 25th anniversary this past Wednesday (3/12/14). As we celebrate the World Wide Web’s silver anniversary, a new report says that Facebook may soon be a step closer to bringing Internet access to the entire world.   This past week, a group of young scientists came to Washington to compete for the top prize of $100,000 in the Intel Science Talent search. We’ll have these stories and much more on this edition of VOA's science, health and technology magazine, "Science World."
