The Female Science Professor is thinking about what advisors owe their students: When I got my PhD and went out into the great big academic world, I felt that I had the respect of my adviser, but I knew not to expect anything more from him in the way of support in my career other… Continue reading Academic Poll: What Do Faculty Owe Former Students?

Changing Standards of Mass
NPR last week had a story about the changing kilogram: More than a century ago, a small metal cylinder was forged in London and sent to a leafy suburb of Paris. The cylinder was about the size of a salt shaker and made of an alloy of platinum and iridium, an advanced material at the… Continue reading Changing Standards of Mass
Precision Measurement Smackdown Explained
Yesterday’s historical physics poll was about precision measurements. Who were those people, and why are they worth knowing about?
Optics Smackdown Explained
Yesterday, I posted a silly poll about optical physicists. Who are those people, and why should you care about them? In inverse order of popularity:
Macroscopic Quantum Behavior in SeedMagazine.com
The Corporate Masters have launched a “featured blogger” program, asking individual ScienceBloggers to comment on news articles from the main site, and publishing the responses with the magazine piece. I just did one on new quantum experiments, which was posted today. The news article is Supersizing Quantum Behavior by Veronique Greenwood. My piece is Reconciling… Continue reading Macroscopic Quantum Behavior in SeedMagazine.com
Thermodynamics Smackdown Explained
So, yesterday featured a silly poll about underappreciated old-timey physicists. Who are these people, and why should you know about them? Taking them in reverse order of the voting:
Pop Quiz Answer
Yesterday’s Michelson Interferometer quiz was surprisingly popular– as of 8:30 pm Tuesday (when I’m writing this), just under 1500 people have voted in the poll, three and a half times as many as in the next most popular poll I’ve done. Who says there’s no audience for physics? So, what’s the right answer, you ask?
Pop Quiz: Michelson Interferometer
Inspired by one of yesterday’s easy questions, a pop quiz for you. The figure below shows a Michelson Interferometer: A laser falls on a beamsplitter, which allows half of the light to pass straight through, and reflects the other half downward. Each of those beams then hits a mirror that reflects it directly back where… Continue reading Pop Quiz: Michelson Interferometer
Entanglement by Accident
It’s been a while since we’ve had any good, solid physics content here, and I feel a little guilty about that. So here’s some high-quality (I hope) physics blogging, dealing with two recent(ish) papers from Chris Monroe’s group at the University of Maryland. The first is titled “Bell Inequality Violation with Two Remote Atomic Qubits”… Continue reading Entanglement by Accident
Plagiarism, Garbling, and Superluminal Motion
I no longer recall who pointed me to this current.com post titled “Scientists Make Radio Waves Travel Faster Than Light “— somebody on Facebook, I think. As it would be a pretty neat trick to make light move faster than light, I took a look. The opening is fairly standard semi-gibberish: Scientist John Singleton insists… Continue reading Plagiarism, Garbling, and Superluminal Motion
