TED-Ed Lesson: The Central Mystery of Quantum Physics

Screenshot of my TED-Ed lesson on particle-wave duality.

My TED@NYC adventure last fall didn’t turn into an invite to the big TED meeting, but it did lead to a cool opportunity that is another of the very cool developments I’ve been teasing for a while now: I’ve written some scripts for lessons to be posted with TED-Ed. The first of these, on particle-wave… Continue reading TED-Ed Lesson: The Central Mystery of Quantum Physics

Nordita Workshop for Science Writers: Wrap-Up

I didn’t write a summary of the third day of “Quantum Boot Camp” to go with my Day One and Day Two summaries for a simple reason: I would’ve needed to do that on Saturday, and I spent Saturday in transit back to the US. More than that, though, it was harder to summarize than… Continue reading Nordita Workshop for Science Writers: Wrap-Up

Nordita Workshop for Science Writers, Day Two

The second day of the “Quantum Boot Camp” was much lighter on talks. The only speaker was Ray Laflamme from the Institute for Quantum Computing in Waterloo, who gave a nice introduction to quantum technologies. While he did spend a bit of time at the start going through Shor’s algorithm for factoring numbers (following up… Continue reading Nordita Workshop for Science Writers, Day Two

Nordita Workshop for Science Writers, aka “Quantum Boot Camp”

Since this part of the trip is actually work-like, I might as well dust off the blog and post some actual physics content. Not coincidentally, this also provides a way to put off fretting about my talk tomorrow… I’m at the Nordita Workshop for Science Writers on quantum theory, which a couple of the attending… Continue reading Nordita Workshop for Science Writers, aka “Quantum Boot Camp”

Impossible Thruster Probably Impossible

Torsion pendulum from the Eot-Wash experiment at the University of Washington.

I’ve gotten a few queries about this “Impossible space drive” thing that has space enthusiasts all a-twitter. This supposedly generates thrust through the interaction of an RF cavity with a “quantum vacuum virtual plasma,” which is certainly a collection of four words that turn up in physics papers. An experiment at a NASA lab has… Continue reading Impossible Thruster Probably Impossible

On Black Magic in Physics

The latest in a long series of articles making me glad I don’t work in psychology was this piece about replication in the Guardian. This spins off some harsh criticism of replication studies and a call for an official policy requiring consultation with the original authors of a study that you’re attempting to replicate. The… Continue reading On Black Magic in Physics

Millikan, Einstein, and Planck: The Experiment io9 Forgot

Schematic of the apparatus Millikan used to determine Planck's constant from the photoelectric effect. Image from the March paper discussed below.

A couple of weeks ago, io9 ran a piece about the old accusations that Robert Millikan manipulated his data for the electron charge with the headlineDid a Case of Scientific Misconduct Win the Nobel Prize for Physics? that got a lot of attention. I wasn’t as impressed with this as a lot of other people,… Continue reading Millikan, Einstein, and Planck: The Experiment io9 Forgot

Non-Inertial Playground Physics

SteelyKid on the merry-go-round used for this experiment.

The Schenectady JCC, where SteelyKid and The Pip go to day care, has a playground with a merry-go-round on it. How this hasn’t been sued out of existence, I have no idea, but it’s a great boon to a physics professor. I’ve used it before to talk about angular momentum, but this weekend I enlisted… Continue reading Non-Inertial Playground Physics

String Experiment: Capillary Action is Complicated

The highly sophisticated experimental apparatus.

As I’ve mentioned here before, I do a lot of work these days in my local Starbucks. This is slightly ironic, as I don’t like coffee– instead, I order tea, which I put in an insulated travel mug. I tend to get the tea, carry the mug back to the table, and let it steep… Continue reading String Experiment: Capillary Action is Complicated

Review and Replication

So, there was this big story in cosmology the other day– Tom Levenson’s write-up is very nice— which has been hailed as one of the greatest discoveries since the last greatest discovery, blah, blah, blah. And now that a few days have passed, we’re starting to see the inevitable backlash, ranging from detailed technical analyses… Continue reading Review and Replication
