Editor’s Note: Geek Madness is our quest to find the greatest geek of all time

The Final Four teams of the 2013 NCAA men’s basketball tournament will battle Saturday afternoon. But more importantly, four of the world’s most epic geeks will face off in Geek Madness beginning today.

Over the past few weeks, our voters have dwindled a group of 32 of the greatest geeks down to just four: Alan Turing, Linus Torvalds, Albert Einstein and Nikola Tesla.

Over on the technology bracket, No. 5-seed Turing and No. 14-seed Torvalds will duke it out for the tech crown. Meanwhile on the science side, two of the most influential scientists ever in Einstein and Tesla will face off.

All four remaining geeks have triumphed over some tough opponents — Turing just trounced the hometown favorite and No. 1-seed Bill Gates, while Tesla squeaked out a victory over the legendary Leonardo da Vinci. See the Elite Eight recaps below.

Final Four voting kicks off right here on the site today, so let your voice be heard. We’ll count up the votes Sunday and the Geek Madness Championship will commence next Monday.
