Thinking from Kansas, Josh Rosenau notices a correlation in data from a Daily Kos poll question on the origin of the universe: Saints be praised, 62% of the public accepts the Big Bang and a 13.7 billion year old universe. Democrats are the most positive, with 71% accepting that, while only 44% of Republicans agree […]

Knowing What’s Essential Is Essential
Spinning off a blog at Inside Higher Ed, the Dean Dad has a post on deciding what classes are essential: My personal sense of it is that the distinction between core and periphery is largely a function of purpose. If your goal in life is to be an exhibited artist, then you might well decide […]
Amazing Laser Application 8: Holography!
What’s the application? Holograms are images of objects that appear three-dimensional– if you move your head as you look at a hologram, you will see the usual parallax effects, unlike a normal photograph, which is fixed. So, if your hologram includes one object that is partly behind another object, you can see around the obstruction […]
There’s More to Science Than Evolution
The National Science Board made a deeply regrettable decision to omit questions on evolution and the Big Bang from the Science and Engineering Indicators report for 2010. As you might expect, this has stirred up some controversy. I wasn’t surprised to learn this, as I had already noticed the omission a couple of months ago, […]
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 […]
What Every Dog Should Know About Quantum Physics
I gave a talk today for a group of local home-school students and parents, on the essential elements of quantum physics. The idea was to give them a sense of what sets quantum mechanics apart from other theories of physics, and why it’s a weird and wonderful thing. The title is, of course, a reference […]
What Should I Go to at the March Meeting?
Lots of good suggestions as to Portland activities for my trip to the March Meeting next week. There’s a second, related problem that I also need help with: What should I do at the meeting itself? My usual conference is DAMOP, which I’ll be going to in May, so while DAMOP is a participating division, […]
The Faulty Fluid Dynamics of Hotel Environmentalism
Boskone this past weekend was held at the Westin Waterfront in Boston, which has these funky double showerheads that they charmingly call the “Heavenly(R) Shower” (hype aside, they are very nice showers). The picture at right is courtesy of lannalee on Twitter, as I didn’t bring a camera. Why am I telling you this? Because […]
Accelerated Twins: The Answer
Yesterday’s post on a variation of the “Twin Paradox” with both twins accelerating was very successful– 337 people voted in the first poll question, as of a little before 9am, and the comments to the original post are full of lively discussion. That’s awesome. I wish I could take credit for it, but the problem […]
The Perverse Economics of College Construction
I’m having a little trouble typing, because the temperature in my office at the moment is around 55 F, and my hands are getting really cold. This is because of “deferred maintenance,” which means “we’re saving money by not maintaining the air-handling systems in our academic buildings (among other things).” The budget has been tight […]
