It’s been a couple of months, so here’s a collection of stuff I’ve written for Forbes recently:

—How Long Does Quantum Tunneling Take?: A look at some new results on one of the most popular questions in quantum physics: Does a tunneling particle spend time “inside” the barrier, or pass through instantaneously?

—How Does Classical Reality Emerge From Quantum Environments?: A look at some experiments that use small-scale artificial “environments” to probe how decoherence happens.

—How Ancillary Technology Shapes What We Do In Physics: Prompted by a question at a public talk, a look at the technological constraints that determine what experiments we do.

—What I Was Wrong About In Physics: Stealing a blog topic from my former ScienceBlogs colleague Razib Khan, a look at places where I’ve changed my mind about physics over the last (almost) twenty years.

—Many Worlds, But Too Much Metaphor: Why I don’t like the way most people talk about the Many-Worlds Interpretation of quantum physics, and what I think would be a better approach.

—Can You Have Infinite Anything And Not End Up With Infinite Everything?: Maybe if you start with neutrinos?

This stretch is a pretty good demonstration of the inherently frustrating thing about modern blogging, in that I’m about equally happy about all of these as pieces of pop-physics writing, but the response to them has been wildly different. The tunneling one got tons of readers, but next to no discussion on social media, while the Many-Worlds one was basically The Velvet Underground and Nico: only a (relative) handful of people read it, but they all had interesting things to say about it.

I don’t really know what if anything can be done about this. I don’t know that I’d be comfortable being any more aggressive in self-promoting these on social media, because I tend to get eye-rolly about other people overdoing that (and also because when I visit my own posts and see the number of auto-playing ads Forbes slaps on these, I recoil…). Mostly, I’m just grateful that I don’t need to rely on blog income to make rent. That said, it’d be nice to have extra beer money…
