The Biggest Ideas in the Universe: Introduction
Why Hacker News recommends it
HN commenters recommend the series as engaging, substantial physics with just enough math for non-specialists.
What it is
Sean Carroll introduces his video series on the biggest ideas in physics, such as symmetry, space and matter, as informal discussions with follow-up Q&A videos. This is the short opening video of the series.

The author is [LINK] Shortly after Covid19 started last year, he started a series of videos called "The Biggest Ideas in the Universe", playlist here: [this video] I've watched quite a lot of this so-called 'popular' hard science material on youtube, and this series was by far the best I've run across. His approach is a bit different from most others, and his presentation is engaging, approachable but also fairly substantial. Specifically, he doesn't elide all of the relevant math, but doesn't get too deep at the same time. You'll see a lot of integrals, derivatives and graphs. For example, he talks about an hour on the big idea of 'Change', and another "Space". Perhaps even more interesting are

The Biggest Ideas in the Universe by Sean Carroll, an intro to modern physics, including homotopy and quantum field theory. He does some math but you'll follow if you've finished high school. Don't miss the Q&A videos in between the 26 regular episodes. [this video]

I'd also recommend Sean Carroll. His "Biggest Ideas in the Universe" series is really great: [this video] I'd also recommend his podcast, Mindscape.

Sean Carroll’s Biggest Ideas in the Universe YouTube series is fantastic. Just enough math to be interesting but nothing requiring a math degree. [this video]

Ignoring the moral question in the story, many people are satisfied by saying "haha funny, the cat is both dead and alive" and they just move on. Reading Pratchett for almost 30 years, it has fueled quite an interested in quantum mechanics in me, he subtly introduces QM teasers in almost every book I read. Particularly Mort. As I dropped out of highschool, I didnt have the luck to properly study physics, but in my 30s, I my existential crisis hit, as they say, a man dies twice, and the stupid half dead cat wouldn't leave me alone. And one night the omnipotent youtube algorithm recommended Susskind's lectures to me, then Feynman, Shankar, .. it just kept going. Now I watch and re-watch them b
