"More wine?" "Hmm? Oh, yes, thank you. Sorry, I was--" "Thinking about mathematics, I wager. Prime numbers was it?" "No, just distracted. It's this blasted heat." "It is the longest day of the year." "Yes, but normally not so hot." "Especially here. You think this is hot, visit me in Syene sometime. You think it gets hot here... You would melt in Syene in the summer." "So I hear. I suppose it's the moderating influence of the ocean that keeps us cooler." "That, and we're closer to the Sun." "What?" "It's true. Today in Syene, the Sun will be directly overhead at mid-day, while you still have…
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. The eleventh profile of this round features Benoit Hamelin, a biomedical engineer turned network defense programmer. 1) What is your non-academic job? I am Chief Scientist for Arc4dia, a small company in the computer security and private network defense business. I develop software, lead…
The southeastern sky had been lightening for some time, stars slowly fading away. Off to the west, a band of clouds was moving in, obscuring stars as it came, but they wouldn't make it in time to block the sunrise. A good thing, as the last two dawns had been cloudy. There would be maybe two more chances this year to see if everything worked, then another full turn of the seasons before their next chance. She sat on the cold ground, behind the offering bowls, a bit off the line of the main passage. She was inside the ring of posts marking the final perimeter, but outside what would become…

These days I'm a nuclear physicist who works on the design and characterization of nuclear well-logging tools that are used…
"...and unless the King comes here himself, I'm not to be disturbed." "Yes, of course." The servant bowed out, leaving him alone with the bath. He stepped in, gingerly at first, the water almost too hot to stand. Slowly, he lowered himself down to a sitting position, feeling the heat soak into his tired legs. All day, on his feet, running back and forth, making tests and fending off royal messengers. The gods curse obsessive kings and greedy goldsmiths. He sighed, as the hot water began to ease individual aches that had long since run together as one big knot of pain. More than the bath,…
“We… are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.” -Jill Tarter But that doesn't mean we can't also look to the hydrogen itself, and use its information to learn about where other things may have come from! Image credit: Lionel BRET/EUROLIOS. An extraordinary example of this -- including what's possible, if not yet practical -- comes from looking at the 21-cm emission line of hydrogen, a forbidden transition with the smallest inherent line width of all!

Sixth in this round is an "adult-onset engineer" working at NASA on some cool stuff. 1) What is your non-academic job? I am a thermal engineer at NASA's Jet Propulsion Lab, working in the Cryogenic Systems Engineering group. Our group provides thermal engineering support (both cryogenic…
When you think about cosmology and the fundamental questions scientists are trying to address, you inevitably wind up thinking about dark matter, dark energy and black holes as the three biggest topics that shape our view of the Universe. Image credit: NASA/WMAP science team. But there are plenty of other aspects to this branch of science that deserve at least equal attention, including two important aspects that are rarely talked about with the same fervor or frequency: the highest energy particles in the Universe and the Universe's "dark ages," a period after the formation of neutral…

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 divided into two parts, though the video is not: Part 1: High Precision, Not High Energy: Using Atomic Physics to Look Beyond the Standard Model (Part I) from Chad Orzel Part 2: High Precision, Not High Energy: Using Atomic Physics to Look Beyond the Standard Model (…
The particles of the standard model, some type of dark matter and dark energy, and the four fundamental forces. That's all there is, right? Image credit: Wikimedia Commons user MissMJ, with info from PBS Nova, FNAL, DOE and PDG. What if that isn't true? What if dark energy, for example, isn't simply energy inherent to space itself? What if it isn't just an unusual property of gravitation, but rather a dynamical property that emerges from the Universe: a sort of fifth force? Would there be any way to discover that? Perhaps unbelievably, if this is the case, it may be accessible and testable…
I've been doing a lot of darkness-cursing lately (mostly off-line), so we could stand to have a little candle-lighting. It's been a few years since I last did a round of profiles of scientists outside academia, so let's see if that will fly again... So, if you 1) Have a degree in a STEM field (BA/BS, MA/MS, Ph.D., whatever), 2) Have a career that doesn't involve people calling you "Professor," and 3) Are willing to share answers to a few simple questions about how you got there and how your science background helps, drop me a line. You can leave a comment here, email me (orzelc at steelypips…
The first time you hear about dark matter, it sounds kind of crazy-- asserting that we're surrounded by tons of invisible stuff is usually a good way to get locked up. But the process of its discovery is surprisingly ordinary: it's just what you do when you play cards. Here's the second green-screen video I've done to promote Eureka: Discovering Your Inner Scientist, which comes out three weeks from tomorrow (but can be pre-ordered today!). This one is about card games, modern astrophysics, and why you probbaly shouldn't play bridge against Vera Rubin: For those who dislike video, I'll put…
When our science fiction fills our heads with ideas that could make our lives tremendously improved, we like to believe it's only a matter of time before technology catches up with our imaginations. Indeed, tricorders, wireless communicators and rocket ships were just some of the breakthroughs predicted by sci-fi on their way to becoming commonplace technology. Image credit: Peter Nussbaumer. But many of our dreams are a long way from becoming reality, including human-sized teleporters, wormholes and time travel. What happens when science fiction runs into the cold, hard wall that is…
My new book comes out one month from yesterday, or four weeks from tomorrow. Of course, yesterday was Sunday, and tomorrow's a federal holiday, both lousy times for promotional posts, so I'll drop this in today instead. Here's a promotional video I put together, about how the history of quantum mechanics can be compared to working a crossword puzzle: This is basically the talk I gave at TED@NYC last year, done in front of a green screen with slides edited in behind me for that An Inconvenient Truth vibe (Nobel committee, take note...). With some bonus cute kid photos and an explicit…
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 to illustrate general relativity). Specifically, I was hearing a lot from students who didn't understand the point of what was supposed to be weird about those. So I was trying to think of how to do a demo, when I realized we could measure the change in geometry that…
I'm teaching a Gen Ed course on relativity this term, which means I'm spending the last few weeks of the term discussing black holes. Which, in turn, means there was no way I couldn't use that story about Kip Thorne calculating the appearance of a black hole for the movie. Especially since I have the students reading Thorne's book. And that, in turn, meant I needed to see the movie. So we got a sitter for the kids Saturday night, and went to the local theater to check it out. And, you know, it's pretty much what it's advertised as: A very pretty giant SF movie, with all that implies, both…
