Rabbi Yair Chayim Bachrach (Chavos Yair Responsum 115), while rabbi of Koblenz in the mid-17th Century, was asked about a certain wealthy individual who lived on the other side of the Rhine as the main Jewish community. This individual, whose name is given as "Berman", wanted to come to synagogue on Shabbat and Holidays. During the summer, there were large ...

The Gemara in Eruvin 43b discusses how R. Gamliel was able to measure the distance. The Gemara says that R. Gamliel had a hollow tube with which he was able to look and sight a distance of 2000 Amos. Per Rashi a long hollow tube narrows and shortens the viewer's range. The length of the tube can be calibrated to yield a maximum sighting distance of 2000 ...

The source is Megila 29. תניא ר"א הקפר אומר עתידין בתי כנסיות ובתי מדרשות שבבבל שיקבעו בא"י שנאמר כי כתבור בהרים וככרמל בים יבוא, והלא דברים ק"ו ומה תבור וכרמל שלא באו אלא לפי שעה ללמוד תורה נקבעים בארץ ישראל, בתי כנסיות ובתי מדרשות שקורין ומרביצין בהן תורה עאכו"כ

It doesn't seem like the Teva had a Deck according to some of the story's details. According to Midrash, Og was hanging onto the outside of the Teva, in the water, and the Re'emim were tied to the sides (with their faces in a hole on the side of the Teva to breathe). If there was a deck, Og and the Re'emim could have just stood on it. If Noach could go ...

People often incorrectly think that the prohibitions in force on Jews on the Sabbath have to do with not 'working'. This is not exactly correct. One may hear people say that "in the old days" it was a lot of work to make a fire (and thus light) but now all we have to do is flip a switch, so now it is not work and is ok to do. This incorrect thinking is ...

The Lubavitcher Rebbe explains as follows (Likkutey Sichos vol. 25, pg. 28 - adapted in English here): The Ark contained a pair of every species of animal known to man. The fact that they could co-exist in a structure measuring 300 X 50 X 30 handbreadths for an entire year was nothing short of a miracle. In fact, it was a taste of the Messianic era when, ...

There are a number of issues: A flying object/tent is not considered a tent to separate. Something that is Mekabel Tum'ah cannot separate. A Kohen may not put himself in a circumstance of Tum'ah upon which a Nazir would have to shave and start over Nezirus. The fact that the airplane MAY fly over Jewish Graves would probably be because it's like flying ...

I found the Rivevos Ephraim 3:206 who addresses this issue. He says that in a Reshus harabim it is forbidden. He also mentions we don't ride bikes and this is similar. He references Shmiras shabbas khilchita 15:13. He ends off saying that his wife claims that it should be forbidden because of digging up dirt and uprooting grass. He says that even if there ...

שערים המצוינים בהלכה‎ quotes a discussion regarding traveling in "קרוניות חשמליות" (city trams), and cites several potential issues. He quotes the שו״ת בית יצחק who compares it to riding an animal on Shabbos, as well as the possibility that more passengers place a larger burden on the electronic motor (not sure if this would be a problem on a subway). ...

I can't fully answer the question, but I do remember a story: A Jew who was driving once stopped a great Rav (I'm sorry that I don't remember who) walking to shul on Shabbos, and asked for directions. The people walking with the Rav expected him to berate or at least ignore the driver, but instead the Rav gave him very exact and detailed directions. After ...

They didn't ignore his suggestion. This is how the pesukim go (according to Malbim): 1:12 — Yonah tells them that the storm is to punish him and not them, and since it's here to punish him for running away, they should throw him away so he can get his punishment. 1:13 — They reasoned that since the punishment is for running away, it would be more ...

There is alot on this topic. Some say 10 people should accompany the Torah. Also it is customary to cover it with a tallis. The Torah should not pass by dirty areas. For more of a comprehensive idea see here.

Tefillin should not be left in the car, particularly on a hot day. If you have no choice then put them in a freezer bag or insulated bag. The parshios are at greater risk than the retzuos. Also why not keep them in the car when driving. At least the temperature is regulated by a/c or heat. I'd assume the inside of the spare tire is under the hood or outside ...
