宇宙中最大的那些想法 01：导论

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.

Why HN likes it: HN commenters recommend the series as engaging, substantial physics with just enough math for non-specialists.

“Just enough math to be interesting but nothing requiring a math degree.”
