Small College, Exotic Particles

Topping the looooong list of things I would give a full ResearchBlogging write-up if I had time is this new paper on a ultra-cold atom realization of “Dirac Monopoles”. This is really cool stuff, but there are a lot of intricacies that I don’t fully understand, so writing it up isn’t a simple matter. The… Continue reading Small College, Exotic Particles

Appearances and So Forth

Since somebody asks nearly every time I mention my TED@NYC appearance back in October, I can now confirm that I will not be speaking at TED this year. Which I found out the same way as everybody else: when the full speaker list for this year’s TED was released today. If you’re curious about the… Continue reading Appearances and So Forth

Uncertain Dots, Academic Blogs

Last week, a comment I made on Twitter about the annoyance of doing merit evaluation paperwork led to some back-and-forth with Rhett Allain and the National Society of Black Physicists Twitter account about whether blogs can or should count toward academic evaluation. This seemed like a good topic for another video hangout with me and… Continue reading Uncertain Dots, Academic Blogs

God Save English Professors From Teaching Undergrads

On the bright side, I’m unlikely to read anything more stupid and insulting today than this Inside Higher Ed article arguing that it would be wrong to shrink graduate programs in English, because the higher education market is Special: When you shrink graduate student enrollments (the supply side), you inevitably also shrink the size of… Continue reading God Save English Professors From Teaching Undergrads

Sticky Tape: The Final Chapter

Simulated results for charged tapes, using the toy model to simulate the force between a charged tape and an uncharged but polarizable one.

I realize people are getting sick of reading me talk about this charged-tape business, which has run to one, two, three, four posts at this point. Truth be told, I’m losing enthusiasm for it myself. So this will be the final post, at least for now… As I mentioned on Twitter, as I type this… Continue reading Sticky Tape: The Final Chapter

Reductionism Is Not Fundamentalism

Ashutosh Jogalekar has a response to my post from yesterday complaining about his earlier post on whether multiverses represent a philosophical crisis for physics. I suspect we actually disagree less than that back-and-forth makes it seem– he acknowledges my main point, which was that fundamental theoretical physics is a small subset of physics as a… Continue reading Reductionism Is Not Fundamentalism

Repeat After Me: Particle Physics Is Not All of Physics

The very last section of the book-in-progress (at least the draft that’s with my editor right now…) is titled “Science Is Never Over,” and talks about how there are a nearly infinite number of phenomena that you can investigate scientifically. The universe is a never-ending source of amazement and wonder, with surprisingly rich dynamics in… Continue reading Repeat After Me: Particle Physics Is Not All of Physics

The Tricky Thing About Simulated Dynamics

The minimum separation as a function of the release position in the toy model of the charged tape system.

In the previous post about simulating the attraction between sticky tapes using VPython, I ended with a teaser mentioning that there was a discrepancy between the simulation and the theoretical solution from directly solving the equations. The problem is kind of subtle, but clearly visible in this graph from that post: In this, we see… Continue reading The Tricky Thing About Simulated Dynamics
