Physics Blogging Round-Up: July

Another month, another collection of blog posts for Forbes: — The Physics Of Century-Old Mirror Selfies: Back in the early 1900’s there was a brief vogue for trick pictures showing the same person from five different angles; this post explains how to do that with mirrors. — Why Research By Undergraduates Is Important For Science…

Physics Blogging Round-Up: June

To make up for last month’s long delay in posting, I’ll knock out this month’s recap of Forbes blog posts really quickly. Also, I still have Vacation Brain, so writing anything really new isn’t in the cards… — What Should Non-Scientists Learn From Physics?: You probably won’t be surprised to hear that, in my opinion,…

Physics Blogging Round-Up: March

Another month, another batch of blog posts at Forbes: — In Physics, Infinity Is Easy But Ten Is Hard: Some thoughts on the odd fact that powerful math tricks make it easy to deal uncountably many interacting particles, while a smaller number would be a Really Hard Problem. — New Experiment Explores The Origin Of…

I mentioned in passing in the Forbes post about science funding that I’m thoroughly sick of hearing about how the World Wide Web was invented at CERN. I got into an argument about this a while back on Twitter, too, but had to go do something else and couldn’t go into much detail. It’s probably…

Physics Blogging Round-Up: February

Another month, another collection of physics posts from Forbes: — Quantum Loopholes And The Problem Of Free Will: In one of those odd bits of synchronicity, a previous post about whether dark matter and energy might affect atoms in a way that allowed for “free will” was followed shortly by a news release about an…

Physics Blogging Round-Up: January

It’s a new month now, so it’s time to share links to what I wrote for Forbes last month: — Small College Astronomers Predict Big Stellar Explosion: I mostly leave astronomy stories to others, but I heard about this from a friend at Calvin College, and it’s a story that hits a lot of my…

So, I tweeted about this yesterday, but I also spent the entire day feeling achy and feverish, so didn’t have brains or time for a blog post with more details. I’m feeling healthier this morning, though time is still short, so I’ll give a quick summary of the details: — As you can see in…

Physics Blogging Round-Up: December

This one’s late because I acquired a second class for the Winter term on very short notice. I was scheduled to teach our sophomore-level “Modern Physics” class, plus the lab, but a colleague who was scheduled to teach relativity for non-majors had a medical issue, and I’m the only other one on staff who’s ever…

Reflections on Matter and Interactions

I’m teaching introductory mechanics for the umpteenth time, using the Matter and Interactions curriculum, as we have for a while. This is going to be my last time teaching out of M&I, though, because last year the department decided to switch to a different book. Starting this winter term, we’ll be using Halliday, Resnick and…

Two-Month Physics Blogging Round-Up

As the post title says, it’s been a whole two months since the last time I did a round-up of my physics blog posts for Forbes. That’s less content than you might think, though, because with the new academic term starting and some deadlines I had for other stuff, I posted basically nothing for most…
