Digging this gem up from the past! Thanks Patrick for these nice visualizations. I keep repeatedly bringing it up every time I have to talk about SOP and "phase" :)
Patrick Ferrand@PFerrandFresnel
When vortex light beams are addressed, it is easy to get confused about the phase and the state of polarization (SoP) of a beam. Below a thread to clarify all this, I hope… ⤵️

When an "imaging artifact" turns out to be one of the wildest things we've ever observed in the universe. A supermassive black hole. Ejected from its galaxy. Compressed gas in its wake. AND FORMED A 200,000 LIGHT-YEAR LONG STRING OF STARS. WHAT.

@MDPIOpenAccess Sending incessant manuscript review requests [3+ in a month] isn't a very good idea. I would love to get on a do-not contact list if possible.

⚡️Preprint: Why do tree-based models still outperform deep learning on tabular data?
We give solid evidence that, on tabular data, achieving good prediction is easier with tree methods than deep learning (even modern architectures) and explore why

(Thread) In the first What If? book, I answered a question about cooking a steak by dropping it from space. At one point, I commented—jokingly!—that if anyone put a steak in a hypersonic wind tunnel to gather better data, I’d love to see the video. Well, I have good news.

Here's a (hopefully) much neater thread on #Article6 and what's happening here #COP27.
But let's not bury the lead: what's being set up is a system of potentially 💩 💰 for carbon.

Some places are more inspiring than others for science! After hearsay for more than a decade, I am finally in Erice at the Ettore Majorana foundation, and I doesn’t disappoint #phoremost2022
