“You wanted to see me, Herr Professor?” “Hans! Yes, come in, come in. Just going over the account books. Frightful amount of money going out of this place.” “Well, radium is expensive…” “Ha! Oh, and speaking of which– here’s one of the sources. Absent-mindedly dropped the fool thing in my pocket last night when I…

Scientific controversies aren’t always settled by a single dramatic experiment, but it’s a lot of fun when they are. It’s even more fun when they can be carried out with, as the author put it, “without any other apparatus than is at hand to every one.” I’m speaking in this case of the famous “double…

I tooke a bodkine gh & put it betwixt my eye & [the] bone as neare to [the] backside of my eye as I could: & pressing my eye [with the] end of it (soe as to make [the] curvature a, bcdef in my eye) there appeared severall white darke & coloured circles r, s,…

PNAS: Asad Aboobaker, Thermal Engineer

I’ve decided to do a new round of profiles in the Project for Non-Academic Science (acronym deliberately chosen to coincide with a journal), as a way of getting a little more information out there to students studying in STEM fields who will likely end up with jobs off the “standard” academic science track. Sixth in…

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…

General Relativity With Toddler Toys

A couple of times last week, I mentioned on Twitter that I was going to demonstrate relativity with toddler toys and string. This was an inspiration that hit late on Thursday, when I was trying to think of a better way to explain embedding diagrams (the technical term for those stretched-rubber-sheet pictures that everybody uses…

I’m teaching relativity in a course with an astronomy prefix, which means I’m obliged to talk about stars and stuff. Yesterday’s lecture was about neutron stars, and how their existence was confirmed by the discovery of pulsars (with the story of Jocelyn Bell Burnell included). This requires some discussion of angular momentum to explain how…

Particle Fever and Modern Art

As mentioned last week, I was the on-hand expert for the Secret Science Club’s foray into Massachusetts, a screening of the movie Particle Fever held at MASS MoCA. This worked out nicely in a lot of respects– it gave me an excuse to visit the newly renovated Clark Art Institute in Williamstown and check out…

On Not Talking, for the Right Reasons

Over at Backreaction, Bee has a nice piece on our current age of virality. Toward the end, she discusses some of the ways this applies to science, specifically a quote from this Nature article about collaborative efforts to measure “big G”, and a story about a Chinese initiative to encourage collaboration. She writes of 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…
