I think a good discussion on non-Archimedean analysis, Local/Global Field theory, or some other areas in algebraic number theory would be a great complement to some of these physics videos.  For instance, discussions of completely disconnected topological spaces or neighborhoods at Planck's length.  The physics is amazing to hear about but the mathematical aspect even without applications is really fruitful to think about.,(reply>), Aᴘᴘʀᴇᴄɪᴀᴛᴇ ʏᴏᴜ ғᴏʀ ᴡᴀᴛᴄʜɪɴɢ❤<br>👆Dᴍ ᴍᴇ ᴏɴ ᴡʜᴀᴛsᴀᴘᴘ ᴡɪᴛʜ ᴛʜᴇ ᴀʙᴏᴠᴇ ᴅɪɢɪᴛs ɪ ʜᴀᴠᴇ sᴏᴍᴇᴛʜɪɴɢ sᴏ sᴘᴇᴄɪᴀʟ ᴛᴏ sʜᴀʀᴇ ᴡɪᴛʜ ʏᴏᴜ❤
