Copernicus Day for May 2025 has arrived, a day for long-range weather fans around the world! Let's take take a look at what the data is showing for the upcoming summer 🧵

Congratulations to Judge Susan Crawford on her victory, and to the people of Wisconsin for electing a judge who believes in the rule of law and protecting our freedoms.

Breaking! The FBI has sued Trump/DOJ! A group of FBI agents who assisted in criminal investigations stemming from the Jan. 6 assault on the U.S. Capitol has filed suit Tuesday to block the Justice Department. youtube.com/watch?v=h3EM2T…

@PhysInHistory Faith.

In your opinion, What idea will always escape numbers and equations? ✍️

After going out with police to observe reports of possible drones, I was with the help of civilian pilots and others able to do deeper analysis and concluded that most of the possible drone sightings that were pointed out to me were almost certainly planes. Let me explain: THREAD

@PhysInHistory Time is a sequence of events. youtube.com/watch?v=feBT0A…

In your opinion, what is time ? ✍️

@PhysInHistory In Physics, Time is a sequence of events.

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

Had a lot of fun teaching physics to some brilliant young minds @SquashBusters. Who says professors can't handle teenagers? (Spoiler: they ask tougher questions than my grad students.) @brownengin

Fabulous book, in general, and especially the introduction, which confirms my beliefs about the meaning of the words models, theories, metaphors.

@stan_sdcollins Nice, Stan. Thanks for sharing. Rhode Island is experiencing a drought now, the worst Fall season drought on record.

New #harrislab open-source hardware released! Introducing FIEVel: A Fast InExpensive Velocimeter based on an optical mouse sensor. The device can nonintrusively measure pointwise x-y velocities at rates up to 6.4 kHz, all for around $100. @arxiv: arxiv.org/abs/2410.23176

@helenrey @kilroi22 I buy afforadable physics teaching supplies and lab equipment from both Arbor Scientific arborsci.com and also from The Teachersource, aka Educational Innovations teachersource.com

@JerryJazzani @kilroi22 Looks like you might know a lot about physics equipment - do you know where I can buy inexpensive AP level equipment?

Anyone know where I can get something like this in the US? @kilroi22 ?

@PhysicsRandall It is a double Thistle Tube, aka an Osmosis Apparatus. Membranes are attcahed like Dialysis tubing, a semi-permeable membrane is attached. Water diffuses through the membrane into a concentrated solution to teach Osmosis. flinnsci.com/double-thistle…

Must see discussion of #electionssecurity hosted at @BrownUniversity on Tuesday October 8th from 5-6:30PM. See below for details.
