A nice series of lectures from MIT on the 20th century history of physics (Maxwell's equations, light quantisation, etc.) by David Kaiser. Recorded in fall 2020, just recently shared on their OpenCourseWare youtube channel:

• Lecture 1: Introduction to Einstein, Oppenheimer, Feynman
• Faraday, Thomson, and Maxwell: Lines of Force in the Ether
• Lecture 4: waves in the ether
• Lecture 5: Einstein and experiment
• Lecture 8: rethinking light
• Lecture 9: rethinking matter

Solen är en i det närmaste outtömlig källa av energi och kommer så fortsätta vara under mer än överskådlig framtid. På vilka sätt kan vi utnyttja detta för att lösa energifrågan på jorden? I denna veckas UppTalk Weekly möter vi Tomas Edvinsson som kommer ge oss några av svaren.

UppTalk Weekly den 28 oktober 2022, 31 min 28 s.
Gäst: Tomas Edvinsson, professor vid institutionen för materialvetenskap, Uppsala universitet.
Moderator: Fredrik Engelmark, samverksansledare UU samverkan.

An IUPAC project (apparently in collaboration with CODATA and CIPM, which makes it very official).

• Units of Measure for Humans and Machines, released in Oct 2020
• Digital Representation of Units of Measure in Chem. Int., vol. 42, no. 4, 2020, pp. 36.
• What's the future of digital chemical units?, presentation by Stuart Chalk at ACS Fall in Aug 2021.
• Stop squandering data: make units of measurement machine-readable in Nature vol. 605, 2022, p. 222-224.

Other IUPAC projects on digital standards. Of particular interest to us are Machine-accessible periodic table and Development of a standard for FAIR data management of spectroscopic data.

How do fish swim so quickly? Explained to great effect by professor of applied mathematics Tadashi Tokieda using a bathtub.

Getting enough light is vital for regulating our sleep, combatting depression and seasonal affective disorder and maintaining good physical health.

In this video produced by the American Chemical Society, George Zaidan does a great job presenting a short but fundamental explanation of what an electron is and why that matters (pun intended).

I can really recommend!

There's a chemistry tree.

Looks like good fun, and the data that makes up the genealogy is shared under a CC-BY license (bulk data export requires contacting the site admin), but I have found no mention of the license for the code of the website/project.

Their FAQ is very informative.

I show you how how I made spinning water droplets

Neat!
