On page 227 of the link which was posted by Avrohom Yitzchok he gives a difference which seemed quite compelling to me. When it comes the beam, there is no idea to see the beam for its own sake, it is rather to be able to recognize that the boundary is there, so you see the sign, and that is good enough. Whereas with the Chanuka candle and a Sukka, you have ...

I found the following teshuvah by R. Betzalel Stern, BeTzel HaChochmah 2:16: Regarding someone who travels by airplane from Australia to Israel, and on the way flies over mountains and deserts...In my humble opinion, it seems obvious that as long as he has a clear view, even though he only sees them from a plane flying miles above, he is ...

Taken from an article by Rabbi Aryeh Lebowitz: The Rambam (Avoda Zara 12:6) rules that one is only prohibited from removing peyos with a razor. Cutting peyos off with a scissor that provides a cut as short as a razor is completely acceptable. (The Darchei Teshuva (181:2) writes, based on the Sefer Hachinuch, that one is merely exempt from punishment, but ...

They used a half of a lug of oil in each candle every night, in order that it would last through the longest night of the year (Menachos 88b). A lug is 6 egg volumes. An egg volume is disputed, but it's accepted to be either around 57 (R' Chaim Naeh) or 100 (Chazon Ish) mL. So the volume per candle was about 172 or 294 mL, or about 1200 or 2050 mL total.

I heard the following from Rabbi Heinemann, in answering this question (specifically he was asked about R' Moshe's teshuva about the exact height necessary for a mechitza, which has a dearth of prior literature on the subject): There is a famous story in which the Chofetz Chaim was upset because his children wanted to put a floor in his house (which had a ...

The Mishna in Keilim discusses this. Essentially they guessed it, based on the average measurement. Starting from Ch. 14:5, here are some of the measurements: פרק יז - משנה ה: הָרִמּוֹן שֶׁאָמְרוּ, לֹא קָטָן וְלֹא גָדוֹל אֶלָּא בֵינוֹנִי ‏ The pomegranate [mentioned in previous Mishnayot] refers to a medium sized one. [Presumably a fully-ripe ...
