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 thousands 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.
Multiple-TED attendee and human factors expert, Ash Donaldson, wants us to better understand why we believe what we do. In this talk, Ash explains how our minds build belief and then breaks it down, showing us how and why humans are fooled into believing that things like Power Bands, anti-aging treatments and supplements actually work. Along the way, he tells us how as a trainee pilot he managed to nearly get himself killed by allowing his beliefs to rule logic and provable fact.
THE PLEASURE OF FINDING THINGS OUT, Richard Feynman Interview (1981)
BBC Horizon/PBS Nova THE PLEASURE OF FINDING THINGS OUT, Richard Feynman Interview (1981)
Fifty minutes of PURE Feynman! This is the original Horizon Nova interview – essential for any Feynman fan… and for everyone else too!
“I’m an explorer, OK I like to find out!” Richard Feynman, physicist and adventurer extraordinary…
THE PLEASURE OF FINDING THINGS OUT was filmed in 1981 and will delight and inspire anyone who would like to share something of the joys of scientific discovery. Feynman is a master storyteller, and his tales — about childhood, Los Alamos, or how he won a Nobel Prize — are a vivid and entertaining insight into the mind of a great scientist at work and play.
“The 1981 Feynman Horizon is the best science program I have ever seen. This is not just my opinion – it is also the opinion of many of the best scientists that I know who have seen the program… It should be mandatory viewing for all students whether they be science or arts students.”

Anecdotal evidence of enormous Jellyfish population blooms are raising questions: Are we seeing the population suddenly boom?
From Futurity, we learn that these “blooms” are a regular phenomena, and so far, the evidence is that worldwide population is fairly stable.
But to make sure, a group of Jellyfish experts are forming a global database — the Jellyfish Database Initiative (JEDI) — to be used track over 500,000 data points about global jellyfish populations. The goal is to determine if data can confirm if the current blooms are shifting from historical norms. JEDI (heh heh) will be a repository for datasets so that the issue of jellyfish blooms can be continually monitored in the future.
Experts question: Jellyfish really on the rise?
