A short clip from The Big Bang Theory. Subject: Non-Newtonian fluid. In this case a corn starch suspension easily made at home. This makes a liquid which is fluid but becomes solid when force is applied, or in this case as Sheldon says in the next frame not included in this video, "the percussive action of the speaker". I'd embed that video but nobody wants to share the embed code for most of TBBT videos I found.
Of course we know the characters on TBBT are actors playing physicists, but who makes sure what they're saying, or reading, or writing on their white boards is accurate? An actual physicist. His name is David Saltzberg and as a Wired article on Fact Checkers says, he is the most well known of all the fact checkers and he's a rock star because TBBT is the least of his accomplishments.
He has a Bachelor’s degree in physics from Princeton. Ph.D. in physics from the University of Chicago. Post-doc at CERN. Currently a professor of physics at UCLA. Has seen the Large Hadron Collider up close and personal. The Large Hadron Collider! Up close and personal, people!!!!! That list does more for me sexually than a big dick especially because you can't fake it, unlike men and their estimates of dick size, which is inconsequential compared to so many other things in my opinion but that's a post for another day.
