Some people collect stamps. Wolfram Research co-founder and author Theo Gray collects elements. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and hundreds of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table." Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones. Theo Gray is 2011 winner of the ACS Grady Stack Award for Interpreting Chemistry for the Public. The Periodic Table Table is a testament to Theo's love for chemistry -- as well as his Ebay buying habits -- and is full of fascinating stories. Come see for yourself in the latest episode of Bytesize Science.
