It seems that Rambam anticipated certain aspects of Einstien's General Relativity. The traditional view was that time is absolute and constant: "Absolute, true, and mathematical time, of itself, and from its own nature, flows equably without relation to anything external." Issac Newton However, in the Guide to the Perplexed, Rambam sees time ...

For what they're worth, here are my two sheqalim (having recently moved to Israel myself): The Lubavitcher Rebbe explains, per the Gemara and HaRaMBa"M, that a person's mentor should stand out in three qualities: modesty, compassion and kindness. All too often, I have run across Rabbis who have been know-it-alls or who haven't given me the time of day. The ...

"The Rebbe" is sufficient. We all know who we are talking about by now when this is said. People sometimes purposely pretend this is ambiguous for whatever personal reason but we all know who we are talking about. The Rebbe is not only the Rebbe for his chassidim but for all yidden. Even other chassidic Rebbes went to him for brochos and advice (btw there ...

I read about this study last year which seems to confirm the wisdom of the above advice: High caloric intake at ...

In my (limited) experience, this is a fairly common thing. Rabbis often meet many different people in the course of their work, and person A might be a woman who has been looking for a match, while person B might be a man looking for a match. Many derivatives of this exist, such as "person A has brother/sister looking for a match," etc. In this case, ...

One of the most well-known "offenses" is mentioned in Talmud Bavli Rosh Hashannah 25a. Summary: Rav Gamliel, who was the Nassi ("chief") at the time and Rav Yehoshua had a disput regarding the validity of accepting a certain type of witness claiming the citing of the 1st crescent moon.

The offense they took was not personal, but in their capacity as leaders and representatives of Torah Scholars in general. If they allowed themselves to be insulted without protest, they feared there would be loss of honor for the Torah.

The term "rabbi" means that the person received semikha (not to be confused with the modern form of semikha which is different). There was no semikha in Bavel, so none of the amoraim who lived there were "rabbi" unless they came to Eretz Yisrael. An easy way to remember this is by looking at the last letter of the word. "Rav" ends with ב which is also the ...

Chazal knew that metal utensils can absorb the taste of food, despite being seemingly perfect. Modern engineers also discovered that micro-fissures are created in metal by expanding and contracting, letting the taste of food enter it. See Dave's answer to "Blias" in today's pots and pans.

An excerpt from Alei Shur (Shaar Rishon Ch. 12 p. 56): והנה בערך בזמנו של רבנו הקדוש היה חי באלכסנדריא האסארונום הגדול פטולימייוס מחבר ספר האלמגסט שמתוכו למדו אסטרונומיא עד הזמן החדש. כאשר נודע לפטולימייוס זה על מחזור הי"ט שנה והידיעות הברורות בחשבון סיבוב הלבנה וכו' עליהן הוא מתבסס - השתומם מאד, כיצד היתה בידי חכמי ישראל ידיעה שחכמי האומות טרם עמדו ...
