Lectures on theoretical physics from Cambridge University professor David Tong.
David Tong at Cambridge is a gifted educator and communicator who has written lecture notes that span a wide swath of the physics curriculum, from introductory material on mechanics through advanced graduate-level treatments of quantum field theory. Truly, these are a fantastic resource, made freely available.

I particularly like his notes on solid state physics (which contains links to other resources).
In Engine Trouble, an animation by Nate Milton, Krulwich shares how Earth’s delicate balance was transformed by the invention of the modern engine.
Nice, informative video. 7 min long.
Via Colossal and The kids should see this.
I show you how how I made spinning water droplets

In this video, Derek Muller tries to find the correct answer to why bicycles are stable.
There's also a Youtube playlist.
From City University of New York, a paper on a bit of the physics relevant to the pandemic - specifically the issue of aerosolized droplets and air circulation in rooms.
The conclusion is that, based on common convection patterns, the 2 meter separation rule is not enough in the absence of a properly designed air filtration system.
