Video sneak preview - what do you think?
Added 2023-06-29 19:34:12 +0000 UTCHi All,
This video will be going live in the next few days and I would love to get your feedback. There are still a number of sections where we are missing visuals but please let me know what's working for you and what is confusing. And let me know if you spot any mistakes etc.
I cannot thank you enough for supporting the channel and for providing feedback on early drafts of videos. It really helps to have extra pairs of eyes check over everything and help shape the narrative.
Best,
Derek

For me, the section on heat engines at the beginning was too long, and confusing - and I'm still not sure why it was necessary. Most people understand the concept that any machine loses energy to its surroundings through friction, etc, but to my mind the overlong heat engine section didn't really clarify that at all. I understand that it formed part of the history of the 'discovery' of Entropy as a concept, but I don't think that fully justifies it. A good friend of mine, a movie director, once said "if you're having trouble with a scene, try reading the script without it".
