Sick Science! - Exploding Bubbles
The term “burst your bubble” takes on a whole new meaning when our science guy, Steve Spangler, is invited to the play date. It’s probably safe to bet that these are no ordinary bubbles, but it’s also no ordinary problem that we’re facing with rising carbon dioxide levels in our atmosphere.

Neil deGrasse Tyson: How the Moon May Have Formed
How was the Moon formed, and why doesn’t it have more iron or heavy metals? Neil deGrasse Tyson explains to Eugene Mirman how a collision with a Mars-sized object during the formation of the Earth may have led to the creation of the Moon. Enjoy this “Behind the Scenes video” from StarTalk Radio.

Crystals are ordered, complexly symmetrical, and even dynamic in their growth and dissolution. It’s no wonder we’re attracted to these chemical lattices as an art form. Linden Gledhill’s new montage of microscopic crystals and food dyes takes that to its aesthetic apex. In this great video, he uses them as a colorful backdrop to a track off Jon Hopkins’ (no relation to the medical school) new album Immunity.
See what amazingness can occur when a scientist (Gledhill is a trained biochemist) and an artist join forces? Let’s do more of that.
Check out links to Gledhill’s other microscopic explorations as well as a cool behind the scenes look at which chemical reactions made the colors you’re enjoying at The Creator’s Project (also on Tumblr).

How Do Tornadoes Form?
Every year tornadoes rip through the U.S. Midwest, leaving death, injury and billions of dollars of damage in their wake. Where do these twisters come from, and just how nasty can they get? Scientific American editor Mark Fischetti reports.

Taylor Wilson: My radical plan for small nuclear fission reactors
Taylor Wilson was 14 when he built a nuclear fusion reactor in his parents’ garage. Now 19, he returns to the TED stage to present a new take on an old topic: fission. Wilson, who has won backing to create a company to realize his vision, explains why he’s so excited about his innovative design for small modular fission reactors — and why it could be the next big step in solving the global energy crisis.

Your Mass is NOT from Higgs Boson
The Higgs Boson is awesome but it’s NOT responsible for most of your mass!
The Higgs mechanism is meant to account for the mass of everything, right? Well no, only the fundamental particles, which means that electrons derive their mass entirely from the Higgs interaction but protons and neutrons, made of quarks, do not. In fact the quark masses are so small that they only make up about 1% of the mass of the proton (and a similar fraction of the neutron). The rest of the mass comes from the energy in the gluon field. Gluons are massless, but there is so much energy in the field that by E=mc^2 there is a significant amount of mass there. This is where most of your mass comes from and the mass of virtually everything around you.

Hangout with CERN: Extra dimensions
Authors of two of the most cited papers in physics for the past ten years, this hangout features special guest theorists Lisa Randall from Harvard University and Raman Sundrum from University of Maryland, who join CERN physicists to look at how the LHC experiments are investigating extra dimensions.
Our host, physicist Steven Goldfarb connects from the ATLAS experiment control centre with physicist Christophe Clement from Stockholm University, Sweden and Taylor Bayouth a CERN Visitor from Los Angeles, with Achintya Rao monitoring questions on social media. Also joining the discussion is CMS experiment physicist Sam Harper from Rutherford Appleton Laboratory, UK.
Recorded live on 25th April 2013.
The hangouts with CERN answer questions received via #askCERN on Twitter and Google+ and via YouTube and Facebook comments.

Einstein’s Jewish Science? Looking at Physics, Politics, and Religion (Steve Gimbel)
Presented by Steve Gimbel, Chair, Department of Philosophy, Gettysburg College on April 13, 2013 in Bethesda, MD.
Between the world wars, Nazi sympathizers tried to denigrate the theory of relativity by calling it “Jewish science.” The Nazis, of course, were wrong. The notion of “religious science” usually brings to mind creationism, but our two best theories of gravitation before Einstein, those of Rene Descartes and Isaac Newton, bore indelible marks of their founders’ theology. How did science change in the time leading up to Einstein to remove theological influence from physics?
Dr. Steve Gimbel is author of Einstein’s Jewish Science: Physics at the Intersection of Politics and Religion and chair of the Department of Philosophy and Edwin T. and Cynthia Shearer Johnson Chair for Distinguished Teaching in the Humanities at Gettysburg College.
