I must admit that the details of how the fields are coupled went over my head, but I found the rest of the video quite accessible. Professor Copeland is a joy to listen to, and Brady asks great questions as usual.

I also learned that "inflation" and "the big bang" are not synonymous, and inflation occurred first.

Not very practical, but the chemistry is interesting. Producing a strong acid from a weak acid by using precipitation as the driving force is something I don't see very often.

A bit of analytical chemistry for a change. I had never heard of a pycnometer!

Very useful video. Nitrate salts are a foundational feedstock in amateur (and professional) chemistry.

NurdRage has published a couple videos on oleum synthesis:

• Lab Notes - Making Oleum - Successful - (April 21-2024)
• Lab notes - Making Oleum - 20% yield improvement - (May 4th - 2024)

Still optimizations to be done, but cool work so far. I love that one of the OG chemistry YouTubers is still doing interesting work.

A long-time viewer of Periodic Videos grew up to study chemistry, and invented a new synthetic route for thalidomide.

Also, TIL that thalidomide still has several medical uses, as long as the recipients are not pregnant.

Six stories of parthenogenesis:
