A reader emails to ask about a new-to-me theory of physics, called “Quantum Space Theory” being promoted by a fellow named Thad Roberts. I wouldn’t usually bother with this, but Roberts was one of the speakers at TEDx Boulder. this is disappointing, to put it mildly– TED is a respected organization, and I don’t like… Continue reading Technology, Entertainment, and Quantum Kookiness

P=???
the hot topic in mathematical sciences at the moment is the draft proof that P≠NP (warning: PDF). This is one of the biggest issues in computer science, and one of the Clay Mathematics Institute’s Millennium Problems, so a proof would be Big News in math/CS, and earn the prover a cool $1,000,000. Reaction among blogging… Continue reading P=???
All the Myriad Inceptions
In comments to yesterday’s post about my favorite Many-Worlds story, a couple of people mention “All the Myriad Ways,” a Larry Niven short story. I don’t think I’ve ever actually read the story, but it gets brought up all the time, so I’m familiar with the concept. It’s an angle on Many-Worlds that I don’t… Continue reading All the Myriad Inceptions
Many-Worlds in Fiction: “Divided by Infinity”
Today, Tor.com has posted the complete story “Divided by Infinity” by Robert Charles Wilson. This remains probably the best science fiction story ever using the Many-Worlds interpretation of quantum physics (though it doesn’t call it that explicitly), and also the creepiest: In the year after Lorraine’s death I contemplated suicide six times. Contemplated it seriously,… Continue reading Many-Worlds in Fiction: “Divided by Infinity”
What’s a Photon, and How Do We Know they Exist?
A reader emailed me with a few questions regarding How to Teach Physics to Your Dog, one of which is too good not to turn into a blog post: What is a photon from an experimental perspective?… Could you perhaps provide me with a reference that discusses some experiments and these definitional issues? The short… Continue reading What’s a Photon, and How Do We Know they Exist?
Virginia Heffernan Is Our Target Audience
There’s a great post at NeuroDojo on the Heffernan business this weekend, and what the take-away ought to be: Yeah, let’s criticize that she didn’t get past the first impression of science blogs. We should expect Heffernan to look before leaping – she writes for the Times, after all, which still has a certain reputation… Continue reading Virginia Heffernan Is Our Target Audience
How Do Superconductors Work?
In the reader request thread, Brad asks about superconductors: Why is a room temperature superconductor so hard? Why do things have to be cold for there to be no resistance (I can guess, but my knowledge of super conductors consists of the words “Cooper pairs” which does not get me very far.) Since next year… Continue reading How Do Superconductors Work?
Quantum Measurement Lotto
Thoreau at Unqualified Offerings gets credit for inspiring two posts today with his proposed Murphy’s Law experiment and this one, about an unrelated issue in quantum measurement. This is an analogy suggested by a colleague a couple of years ago, comparing the projection of a quantum wavefunction in the measurement process to the lottery. The… Continue reading Quantum Measurement Lotto
Murphy Violation in Science
Over at Unqualified Offerings, Thoreau proposes an an experimental test of Murphy’s Law using the lottery. While amusing, it’s ultimately flawed– Murphy’s Law is something of the form: Anything that can go wrong, will. Accordingly, it can only properly be applied to situations in which there is a reasonable expectation of success, unless something goes… Continue reading Murphy Violation in Science
The Full Seminar Experience
Avi Steiner emailed me with a set of questions that are too good not to turn into a blog post: Being a math/science major at a small liberal arts college, I unfortunately never get the “full” experience of a math/science talk. Since I do plan on eventually attending grad school, I thought it might be… Continue reading The Full Seminar Experience
