Probing the Early Universe through Observations of the Cosmic Microwave Background

This lecture/talk is a few years old, but it was only made public on the IAS channel last week (…along with a lot of other lectures – the IAS channel has added a lot of stuff recently, including more than 150 lectures within the last week or so; so if you’re interested you should go have a look).

Below the lecture I have added a few links with stuff (wiki-articles and a few papers) related to the topics covered in the lecture. I didn’t read those links, but I skimmed them (and a few others, which I subsequently decided not to include as their coverage did not overlap sufficiently with the stuff covered in the lecture) and decided to add them in order to remind myself what kind of stuff was included in the lecture/allow others to infer what kind of stuff might be included in the lecture. The links naturally go into a lot more detail than does the lecture, but these are the sort of topics discussed/included.

The lecture is long (90 minutes + a short Q&A), but it was interesting enough for me to watch all of it. The lecturer displays a very high level of speech disfluency throughout the lecture, in the sense that I might not be surprised if I were told that the most commonly word encountered during this lecture was ‘um’ or ‘uh’, rather than more commonly encountered mode words like ‘the’, but you get used to it (at least I managed to sort of ‘tune it out’ after a while). I should caution that there’s a short ‘jump’ very early on in the lecture (at the 2 minute mark or so) where a small amount of frames were apparently dropped, but that should not scare you away from watching the lecture; that frame drop is the only one of its kind during the lecture, aside from a similar brief ‘jump’ around the 1 hour 9 minute mark.
