Description

Review of basic astronomical facts, of setira between Shabbas and Pesachim, and of Rabbeinu Tam's solution (2 meanings of 'shekia', shekia as a process). 4+ kushyos against Rabbeinu Tam, which lead into Gra's solution to setira (2 meanings of 'tzeis kochavim'). Geonim, rishonim and earlier acharonim who already disagreed with Rabbeinu Tam. The 3 types of 'dusk' (civil, nautical, astronomical) and their meanings and angles correspond to Gra-Tanya and 2 calculations of Rabbeinu Tam, and this dovetails elegantly with Gra's attack on Rabbeinu Tam from alos ha-shachar (kushya 4) and with the Rav applied to the Gra.
