How to Teach Physics to [Your Pet’s Name Here] (DonorsChoose Challege 2010)
As you may or may not be aware, we are once again in the middle of a DonorsChoose fundraiser to support public school students and teachers. The good news is, the Uncertain Principles entry for the 2010 Challenge is in second place among ScienceBlogs blogs with $373 in donations thus far; the bad news it… Continue reading How to Teach Physics to [Your Pet’s Name Here] (DonorsChoose Challege 2010)
Counterfactual Physics: Lorentz Variance?
The theory of relativity takes its name from a very simple and appealing idea: that the laws of physics should look the same to moving observers as to stationary ones. “Laws of physics” here includes Maxwell’s equations for electricity and magnetism, which necessarily means that moving observers must see the same speed of light as… Continue reading Counterfactual Physics: Lorentz Variance?
What to Tell Your Dog About Einstein
“Hey, dude, whatcha doin’?” “Signing these contracts. I’m not sure why they need four copies, but they do.” “Contracts for what?” “The new book. Remmeber, the one we’ve been talking about these last few weeks? Sequel-of-sorts to How to Teach Physics to Your Dog? About relativity?” “Oh, yeah, that’s right! We’re doing another book! Where… Continue reading What to Tell Your Dog About Einstein
Crazy and Dishonest Physics Update
The problem with writing about fake physics is that once you start, it’s hard to stop. And there’s always something new and disreputable to find, such as this hideous bit of scammery. As I said in How to Teach Physics to Your Dog, if quantum physics really allowed you to amass vast wealth just by… Continue reading Crazy and Dishonest Physics Update
Exploring Hidden Dimensions at the World Science Festival
Since I was going to be down here anyway to sign books at the World Science Festival Street Fair, Kate and I decided to catch one of the Saturday events at the Festival. It was hard to choose, but we opted for the program on Hidden Dimensions: Exploring Hyperspace (Live coverage was here, but the… Continue reading Exploring Hidden Dimensions at the World Science Festival
Relativity on a Human Scale
While I mostly restricted myself to watching invited talks at DAMOP last week, I did check out a few ten-minute talks, one of which ended up being just about the coolest thing I saw at the meeting. Specifically, the Friday afternoon talk on observing relativity with atomic clocks by Chin-Wen Chou of the Time and… Continue reading Relativity on a Human Scale
“Subtle Is the Lord…” by Abraham Pais
The APS now gives out an Abraham Pais Prize for History of Physics, which gives you some idea of how influential his work was, in particular “Subtle Is the Lord…” The Science and Life of Albert Einstein, which won prizes and sits in a prominent position on the bookshelves of many physicists. Like a lot… Continue reading “Subtle Is the Lord…” by Abraham Pais
Amazing Laser Application 6: LIGO!
What’s the application? LIGO stands for Laser Interferometer Graviitational Wave Observatory, because (astro)physicists feel free to drop inconvenient words when making up cute acronyms. This is an experiment to look for disturbances in space-time caused by massive objects, which would manifest as a slight stretching and compression of space itself. What problem(s) is it the… Continue reading Amazing Laser Application 6: LIGO!
So You’d Like to Learn Some Physics…
Via Twitter, Michael Barton is looking for some good books about physics. I was Twitter-less for a few days around the period of his request, and this is a more-than-140-characters topic if ever there was one, so I’m turning it into a blog post. The reason for the request is that he’s going to be… Continue reading So You’d Like to Learn Some Physics…
