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…
