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 Probabilities In Quantum Physics: A write-up of an experiment using a multi-path interferometer to look for departures from the Born rule for calculating probabilities from wavefunctions.

The Most Important Science To Fund Is The Hardest To Explain: In light of the awful budget proposal put forth by the Trump administration, some thoughts on the importance of government funding for the most basic kinds of research.

Popular Science Writing And Our Fascination With Speculation: Prompted by the new book from Jorge Cham and Daniel Whiteson, a look at why so many pop-science books focus on what we don’t know.

Can You Make A Quantum Superposition Of Cause And Effect?: A write-up of a new paper where they put a single photon into a superposition of A-then-B and B-then-A, which kind of makes my head hurt.

I’m pretty happy with these, though I would’ve expected more pageviews for the cause-and-effect thing. My teaching schedule is slightly lighter this Spring term, so I may be able to do a little more in-depth blogging than in recent months. Or maybe not. Come back in May to find out…

    @Chad: Annoyingly off-topic, but …
    Do you know anything about Forbes’s Web situation today? I’d like to read at least three of your articles :-), but Safari is getting malformed HTML (or something), and Firefox just gets stuck in a “Welcome” loop. I have whitelisted Forbes in my AdBlock, but that doesn’t seem to matter.
