Bouncing Neutrons for Fun and Science: “Realization of a gravity-resonance-spectroscopy technique”

Several people blogged about a new measurement of gravitational states of neutrons done by physicists using ultracold neutrons from the Institut Laue-Langevin in France. I had to resort to Twitter to get access to the paper (we don’t get Nature Physics here, and it’s way faster than Inter-Library Loan), but this is a nice topic… Continue reading Bouncing Neutrons for Fun and Science: “Realization of a gravity-resonance-spectroscopy technique”

Wave Nature Gets Bigger: “Quantum interference of large organic molecules”

It’s been a while since I wrote up a ResearchBlogging post, but since a recent paper forced me to update my “What Every Dog Should Know About Quantum Physics” slides with new pictures, I thought I should highlight the work on the blog as well. Not that you could’ve missed it, if you follow physics-y… Continue reading Wave Nature Gets Bigger: “Quantum interference of large organic molecules”

Massive by Ian Sample

The physics book generating the most bloggy buzz in the latter part of 2010 would have to be Ian Sample’s Massive: The Missing Particle that Sparked the Greatest Hunt in Science, about the as yet undetected particle known as the Higgs boson. Detecting the Hiigs is the most immediate goal of the Large Hadron Collider,… Continue reading Massive by Ian Sample

BEC: What Is It Good For?

Another response copied/adapted from the Physics Stack Exchange. The question was: What are the main practical applications that a Bose-Einstein condensate can have? Bose Einstein Condensation, for those who aren’t familiar with it, is a phenomenon where a gas of particles with the right spin properties cooled to a very low temeprature will suddenly “condense”… Continue reading BEC: What Is It Good For?

The Status of Simulations

Most of what would ordinarily be blogging time this morning got used up writing a response to a question at the Physics Stack Exchange. But having put all that effort in over there, I might as well put it to use here, too… The question comes from a person who did a poster on terminology… Continue reading The Status of Simulations

Poll: Top Physics Story of 2010?

It’s the last week of the (calendar) year, which means it’s a good time to recap the previous twelve months worth of scientific news. Typically, publications like Physics World will publish a list of top ten physics stories of 2010, but we’re all Web 2.0 these days, so it seems more appropriate to put this… Continue reading Poll: Top Physics Story of 2010?

Teleportation of Toddler Toys

Today is the official release date for the paperback edition of How to Teach Physics to Your Dog, so I wanted to write up something cool about quantum physics to mark the occasion. I looked around the house for inspiration, and most of what we have lying around the house is SteelyKid’s toys. Thus, I… Continue reading Teleportation of Toddler Toys

Dance of the Photons by Anton Zeilinger

I hadn’t heard anything about Dance of the Photons: From Einstein to Quantum Teleportation before it turned up in my mailbox, courtesy of some kind publicist at Farrar, Straus, and Giroux, otherwise I would’ve been eagerly anticipating it. Anton Zeilinger is a name to conjure with in quantum optics, having built an impressive career out… Continue reading Dance of the Photons by Anton Zeilinger

Interference of Independent Photon Beams: The Pfleegor-Mandel Experiment

Earlier this week, I talked about the technical requirements for taking a picture of an interference pattern from two independent lasers, and mentioned in passing that a 1967 experiment by Pfleegor and Mandel had already shown the interference effect. Their experiment was clever enough to deserve the ResearchBlogging Q&A treatment, though, so here we go:… Continue reading Interference of Independent Photon Beams: The Pfleegor-Mandel Experiment
