Just some good “how does this stuff work” videos

Ben Krasnow’s long-running channel of interesting applications of science and technology, built in a home shop: a working electron microscope, X-ray backscatter, homemade aerogel, electromechanical systems, chemistry, and electronics. Recent uploads include a sodium-water reactor that draws electricity to prevent its own explosion (in theory) and insect imaging with an electron microscope plus femtosecond laser. The gold standard for “how does this stuff work.”

Just interesting stuff.

The Harvard-Smithsonian Center for Astrophysics colloquium channel: weekly research talks from Phillips Auditorium, webcast in 1080p, covering whatever is current in the astrophysics research community — particle physics at the redshift frontier, CMB cosmology, planetesimal disruptions. Uploads have slowed in the last few months, but the archive is 360+ talks of frontier astrophysics for free.
