One of my favorite Christmas presents this year was a Seek Thermal camera to use with my Android phone. This allows for a lot of idle physics-y fun, taking pictures of things in thermal mode. One idea I had was to do a sort of follow-up to the test of my insulated mug that I… Continue reading Thermal Thursday: How Good Is My Mug?

Advent Calendar of Science Stories 21: Hot and Cold
Another weekend day, another story I’m going to outsource a bit. In this case, to the original scientist, who at the time of his discovery was a 13-year-old schoolboy in Tanzania: In 1963, when I was in form 3 in Magamba Secondary School, Tanzania, I used to make ice-cream. The boys at the school do… Continue reading Advent Calendar of Science Stories 21: Hot and Cold
Advent Calendar of Science Stories 17: Kickstarter in 1921
There’s no way I could possibly go through a long history-of-science blog series without mentioning the great Marie Skłodowska Curie, one of the very few people in history to win not one but two Nobel Prizes for her scientific work– if nothing else, Polish pride would demand it. She made a monumental contribution to physics… Continue reading Advent Calendar of Science Stories 17: Kickstarter in 1921
Advent Calendar of Science Stories 6: Party in Mesopotamia
Borne of the flowing water (…) Tenderly cared for by the Ninhursag, Borne of the flowing water (…) Tenderly cared for by the Ninhursag, Having founded your town by the sacred lake, She finished its great walls for you, Ninkasi, having founded your town by the sacred lake, She finished its great walls for you… Continue reading Advent Calendar of Science Stories 6: Party in Mesopotamia
PNAS: Grant Goodyear, Oil Industry Nuclear Physicist
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. Eighth in… Continue reading PNAS: Grant Goodyear, Oil Industry Nuclear Physicist
On “Excessive Technical Detail”
I’ve seen a few links passed around to this Tom Siegfried post about science literacy, which is mostly a familiar story about how polls show most Americans giving incorrect answers to science questions. The sort of stuff you find in the NSF’s Science and Engineering Indicators report. What’s getting the social-media attention, though, is this… Continue reading On “Excessive Technical Detail”
Science at Bedtime
“Daddy? How do you make water?” “You mean, what is it made of?” “Yeah, what’s water made of?” “Hydrogen and oxygen.” “Oh. And what’s hydrogen and oxygen?” “They’re chemical elements.” “So, when we drink water, we’re drinking chemicals?” “Well, yeah. In a sense, everything is chemicals. Water’s a chemical, air is made of chemicals. ”… Continue reading Science at Bedtime
Missing the Eureka Moment
Dmitrii Ivanovich Mendeleev hit on the idea of the Periodic Table as an organizing theme for a textbook he began writing in 1868. He did some work on refining the idea, and in 1870 presented a paper on it to a meeting of the Russian Chemical Society. Well, actually, that’s not quite true– Mendeleev did… Continue reading Missing the Eureka Moment
SteelyKid, Scientist
One of SteelyKid’s classmates came over for a couple hours today. After a bit, they got into the Magic School Bus science kit she got for her birthday, and decided to invent “new kinds of water.” The “featured image” above shows her reinventing stock images… And doing a better job of it than this clown.… Continue reading SteelyKid, Scientist
Interference with 10,000-Particle “Particles”: “Matter-wave interference with particles selected from a molecular library with masses exceeding 10000 amu”
I’m teaching Quantum Optics this term, and one of my students picked “Atom Optics” off the list of suggested paper topics. When he asked for pointers, I said “You should check out the diffraction stuff Markus Arndt’s group does.” And just like that, a paper from the Arndt group turns up from the Arxiv Blog…… Continue reading Interference with 10,000-Particle “Particles”: “Matter-wave interference with particles selected from a molecular library with masses exceeding 10000 amu”
