The author is https://en.wikipedia.org/wiki/Sean_M._Carroll https://en.wikipedia.org/wiki/Sean_M._Carroll Shortly after Covid19 started last year, he started a series of videos called "The Biggest Ideas in the Universe", playlist here: https://www.youtube.com/watch?v=HI09kat_GeI&list=PLrxfgDEc2NxZJcWcrxH3jyjUUrJlnoyzX https://www.youtube.com/watch?v=HI09kat_GeI&list=PLrxfgDEc2N... 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 followup Q&A videos, which are as long as and perhaps even more detailed than the source. Do give the linked six minute intro video a watch.
