Rabbi Baruch Bodenheim: Gemara Shabbos: Perek Kirah, יום שני, Iyar 28 Daf 39a (05/26/25)

Quickly review the גמרא דף לט. “ולא יטמיננה בחול (two dots – middle of the Amud) until the bottom of the Amud 

Question:

There is a machlokes as to why ר’ יוסי agrees it is forbidden to submerge an egg in hot sand on Shabbos. 

Are these reasons mutually exclusive? If yes. Yes?

Learn תוס’ “ואין

Learn תוס’ “אלא

We rule lhalacha like the Rabanan, why does the Gemara spend time explaining the opinion of ר’ יוסי. What relevance does it have?
