Continuity, Discretion, and the Perils of Popularization
Last week’s Seven Essential Elements of Quantum Physics post sparked a fair bit of discussion, though most of it was at the expert level, well above the level of the intended audience. such is life in the physics blogosphere. I think it’s worth a little time to unpack some of the disagreement, though, as it… Continue reading Continuity, Discretion, and the Perils of Popularization
Laser Smackdown: The Most Amazing Use of a Laser?
Way back in the early days of ScienceBlogs, I ran a competition of sorts to determine the greatest physics experiment in history. I collected a bunch of nominations, wrote up a post about each of the top 11 entries, and then asked people to vote for their favorite. In honor of the 50th anniversary of… Continue reading Laser Smackdown: The Most Amazing Use of a Laser?
Single-Photon Cooling: Making Maxwell’s Demon
As mentioned previously, I’ve been reading Sean Carroll’s Wheel arrow of time book, which necessarily includes a good bit of discussion of “Maxwell’s Demon,” a thought experiment famously proposed by James Clerk Maxwell as something that would allow you to cool a gas without obviously increasing entropy. The “demon” mans a trapdoor between a sample… Continue reading Single-Photon Cooling: Making Maxwell’s Demon
Fifty Years of Solutions Finding Problems
2010 marks the 50th anniversary of the invention of the laser. To mark the occasion, the American Physical society has launched LaserFest, which will involve a large number of public events over the next year. The website includes a bunch of cool things explaining the physics of lasers, and a timeline of laser history with… Continue reading Fifty Years of Solutions Finding Problems
Neil Bates Owes Me $160
That’s the bill for the time that I spent on deciphering his supposed falsification of decoherence. I don’t want anyone to fall for his false argument, so here’s the correct explanation of the scenario, to save other people the trouble. The center of his so-called “proof” is this modified Mach-Zehnder Inteferometer: Light enters at the… Continue reading Neil Bates Owes Me $160
Seven Essential Elements of Quantum Physics
The previous collection of things everyone should know about quantum physics is a little meta– it’s mostly talking up the importance and relevance of the theory, and not so much about the specifics of the theory. Here’s a list of essential elements of quantum physics that everyone ought to know, at least in broad outlines:… Continue reading Seven Essential Elements of Quantum Physics
Four Things Everybody Should Know About Quantum Physics
Derek Lowe has a post talking about things biologists should know about medicinal chemistry. It’s a good idea for a post topic, so I’m going to steal it. Not to talk about medicinal chemistry, or biologists, of course, but to talk about my own field, and what everyone– not just scientists– should know about quantum… Continue reading Four Things Everybody Should Know About Quantum Physics
The Bozo Condensate
I’m standing in the kitchen, sipping tea and watching snow blowing across the back yard. It’s cold enough that the digital thermometer has stopped working, which puts it in the single digits Fahrenheit. I’m not looking forward to walking the dog in this. “Pretty cold, dude,” she says. “Yeah,” I say. “It’s cold, all right.”… Continue reading The Bozo Condensate
A Lot of Knowledge Is a Dangerous Thing
I was looking at some polling about science over the weekend, and discovered that they helpfully provide an online quiz consisting of the factual questions asked of the general public as part of the survey. Amusingly, one of them is actually more difficult to answer correctly if you know a lot about the field than… Continue reading A Lot of Knowledge Is a Dangerous Thing
