Rhett Allain has a list of 5 Things Every Human Should Know About Light, to tie in with the International Year of Light, and it’s a good list with lots of .gifs. Of course, there are some gaps, so let me offer some additional things that everyone ought to know about light: — Light Is…

Over at Scientific American’s Frontiers for Young Minds blog, they have a great post on what happens when you ask scientists to explain key elements of a different research field. It’s pretty funny, and rings very true, as SteelyKid asks me tons of science questions, very few of which have anything to do with atomic,…

Quantum Optics: The Game

Over on Facebook, my colleague Chris Chabris was talking up a smartphone game from a company he’s associated with. Which of course got me thinking “Wait, why don’t I have a smartphone game company?” (The Renaissance Weekend is also partly to blame, as I was one of about six people there who didn’t have a…

As I endlessly repeat, I’m an experimentalist by training an inclination, so I especially appreciate stories about experimental science. There’s something particularly wonderful about the moment when an experiment clicks together, usually after weeks or months of hard, frustrating work, when things just keep breaking. Of course, sometimes, breaking stuff can be a Good Thing.…

High Precision, Not High Energy: Video

Back in August, I gave a talk in Stockholm at the Nordita workshop for science writers, about precision measurement searches for physics beyond the Standard Model. There’s now video of this online: The video quality isn’t great, but if you’d like a clearer look at the slides, I’ve posted them on SlideShare. The talk was…

In odd-numbered years (by the Gregorian calendar, anyway), the University of Toronto offers the John Stewart Bell Prize for Research on Fundamental Issues in Quantum Mechanics and Their Applications. This is not connected to the Jon Stewart of the Daily Show– he’s purely classical, as you can tell from the fact that there’s no “h”…

Entangled States at TED-Ed

The fourth video I wrote for TED-Ed is now live: Einstein’s Brilliant Mistake: Entangled States. The title is not just an Elvis Costello reference, but gets at the fact that while the Einstein, Podolsky, and Rosen paper was wrong in that the local hidden variable theories they favored are impossible, it turned out to be…

Schrödinger’s Cat at TED-Ed

The third of the videos I wrote for TED-Ed is now live: Schrödinger’s Cat: A Thought Experiment in Quantum Mechanics.This is using basically the same argument I outlined in this post, but with awesome animation courtesy of Agota Vegso. I’m impressed by how close the images that ended up in the video are to the…

Nobel Prize for Blue LEDs

The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for the development of blue LED’s. As always, this is kind of fascinating to watch evolve in the social media sphere, because as a genuinely unexpected big science story, journalists don’t have pre-written articles based on an early…

Yes Virginia, There Are Quantum Jumps

In a weird coincidence, shortly after I wrote a post about “quantum leap” as a metaphor, I was looking up some stuff about John Bell and ran into mentions of a paper he wrote called “Are There Quantum Jumps?” Bell is borrowing a title from Schrödinger, who wrote a pair of articles (really, one article…
