Actually, it can (at least for my combination of country and vehicle).
Pretty interesting (if not particularly surprising) the promotion of inter-community hatred as well.

"two Bristol graffiti artists... were asked to spray-paint the Islamic shahada - the declaration of faith - in Arabic on a defunct Debenhams in the city centre. One was also asked to spray a Quranic verse about the "devil's handiwork" on a Conservative Club in the city."

"... provided Roman Lavrynovych [low-level criminal] with an anti-Muslim poster, designed to appear like it had been written by a Hindu by referencing the 1992 destruction of an ancient Indian mosque by right-wing Hindu groups. "Every mosque closed = 100 fewer crimes," the poster said."

Also - obviously annual not weekly - don't forget the Reith Lectures (https://www.bbc.co.uk/programmes/b00729d9): long-form lecture series by (often) the most brilliant people of their time. Back catalogue available from 1948 in podcast form. Recommend starting with Bertrand Russell in the inaugural lectures - he's fantastic to listen to, even now.

Apologies for people who've already seen this (it's pretty old and comes round fairly frequently on HN), but for those previously unaware, http://trafficwaves.org/ is one of the best sites digging into the phenomenon from an "educated layman's" perspective.

Re:NASA's clever technique to make combustion chambers on Monday May 01, 2023 @04:47AM (#35770422)
Before metallic 3d printing, NASA used a clever combination of conductive wax and electroplating to achieve the same thing. In this video, the presenter demonstrates the same thing in his workshop.
I did an MSc (at Manchester Uni) after a bachelors in Modern Languages and some time as a (tech) lawyer. (Since the MSc I’ve worked in production support, mostly algorithmic trading, with some light development and integration work as part of that.) Although I don’t think there was anything that I learned there that I couldn’t have got from some dedicated self-learning, I do think the requirement to do some things that were quite difficult or intimidating was very rewarding and has also given me a lot more confidence to dig deeper into the patterns below the surface of program behaviour. (For example, I found the maths behind signals processing really hard, but although I’d imagined that assembly programming would be incredibly difficult I actually found it quite enjoyable to work direct with the “bare metal”.) I thought it was worthwhile. I think the benefits are likely to be more oriented toward your own intellectual satisfaction and depth of knowledge than career enhancement though.
Indeed, though see the article linked at the bottom of that one, which goes into more of the nuance and has distribution curves etc: https://ourworldindata.org/life-expectancy-how-is-it-calcula...
