Artscroll is currently making travel-sized paperback English Gemaras. Each only has about 1 or 2 chapters. Size: 7" x 10" There's also a "personal-sized" paperback Oz Vehadar. Size: 6.5 X 9.5 Blum Edition hardcover travel Gemara. Size: 5.25" X 8.25" Historically, after WWII the Vaad Hatzalah printed pocket sized Gemaras for survivors in the refugee ...

I think I remember learning in elementary school that the Moon and the Sun had, as they have now, the same angular diameter when viewed from the Earth, and they also had coronas of equal size, so their total sizes, including coronas, were equal. When the Moon complained about their equality, literally in terms of a "crown" (which a corona resembles and which ...

Rabbi Moshe Isserlis writes (YD 275:6) about various scribal traditions including large/small letters that אם שינה לא פסל - if [the scribe] deviated, he did not invalidate [the scroll]. Obviously if they can be fixed, one should do so to conform with the tradition.

According to Sefer Hayovelim the height was 13 parsa, 5433 amos and 2 zratot. (Source) This would come out to about 52.5 km. There are sources (such as) that take only the amos, because 50 km is unbelievable, and it doesn't really work out with the way the verse is built (חמשת אלפים וארבע מאות ושלושים ושלוש באמה עלה גבהו, ושתי זרתות ושלוש עשרה פרסה). That'...

Yes, there are standard sizes, though obviously there are usually going to slight variations in fit for every pair of handmade tefilin. The sizes seem to be measured by cm2 millimeters. Based on my experience they tend to err towards a looser fit; I usually adjust this by adding a sticker or a piece of paper on the inside. This piece is sometimes called a "...

To answer your question: It's been said in the name of Reb Chaim Kanievsky that one should not hide one's Peyot behind one's ears, but he never says to cut them. There are plenty well respected Rabbis who hide their Peyot behind their ears, and others who have trimmed Peyot . Just to put this in context, let's go back to basics - using classic sources. ...

The explanation referenced in my answer here (I'm still looking for the underlying source - it must be in some maamar or sicha) seems to indicate that the "diminishment" is closer to your second possibility - though focusing not so much on the moon's waxing and waning, but on the fact that it is not self-luminous but receives its light from the sun. (Is ...

If you're just looking for long talmudic text, there are others in Brakhot with little commentary: See Brakhot 56b, 58. Difficult sugyas with little Talmudic text and plentiful Tosafot/Rashi are qualitatively longer (and scarier!) than the more aggadic, pshat texts. There are a few in Niddah that make you hold your breath when you first turn the page onto ...

Rashi (Baba Batra 75A) explains that both @DoubleAA and @ba are correct. The Talmud (Chagiga 12A) says that Adam was created as tall as one end of the heavens to the other (also described as from earth to the heavens), but after he sinned G-d made him smaller. Rashi (Baba Batra 75A) explains that when G-d made Adam smaller, he shrunk him to 100 Cubits.

This is an argument amongst the achronim. See Yoreh Deah siman 178. The Shulchan Aruch writes not to grow one's hair like the non Jews do and not to shave the sides while leaving the hair on top. Shach there #1 brings the Ateres Zahav who says this is actually all one prohibition. Don't grow hair like them which is shaven on the sides etc. The Shach goes ...

The numbers 34 or 4 found on the batim cases refer to the millimeter measurement of the upper cube of the batim. hence 34mm or 4, referring to 34mm. To follow the opinions of the Rishonim that hold the batim should be 2 'etzbaos (thumb widths) many will be more strict than the Shulchan Aruch, who says that there is no shiur to tefillin. Most hold that the ...

from here, quoting R. Isaac of Homil (a hebrew biography can be found here): The moon, when she was first created, was a glistening jewel. She did not merely reflect light, but rather transformed it and brought out its inner beauty, much as a precious stone glistens with a secret, hidden light all its own. In her own way, the moon was greater than the sun ...

Mincha Gedola is three hours long thus it is the big Mincha. Mincha Ketana is 2 1/2 hours long thus it is the small Mincha. Regarding Plag Hamincha it is the time in between Mincha Ketana and Shekiya, which is half of the time of the Mincha remaining. It does not mean the half time between the two Minchas as there is no Halachic significance to that time. ...

Olas Yitzchak 292 says it is known from the times of the Rambam even though the Rambam did not hold it was necessary. He brings in the name of the Sefer Shaar HaMitzvos - Rabbi Chaim Vital - Parshas Kedoshim in the name of the Arizal. Ben Ish Chai in his Sefer Ben Ish Chayil says that when Mordechai was Muchtar Binimuso it means long Paiyos.

When I was learning in Israel, someone posted an article written by R' Aharon Lichtenstein about having long hair. If I recall correctly, there were 3 issues he raised and evaluated: 1) Interruption for tefillin: There is a dispute between the Machatzis Hashekel and the Pri Megadim as to whether hair is an interruption on the spot it is grown, or ...

The Talmud, also in Zevachim later on (97b), identifies the biblical 'mizrak' with the 'agan' (אגן); see also Ex. 24:6. Elsewhere in the Talmud (Ber. 22a), the agan is depicted as a tub that can contain enough water to bathe in (9 kav; aprox. 3 gallons). (In biblical descriptions they are both typically used to illustrate large, excessive/exaggerated ...

I'm not sure about Rav Ben-Tzion Abba Shaul (I'd be very interested in hearing if anyone knows), but Rav Menashe Klein (Mishneh Halachos 7:121) quotes from R. Chaim Zvi Manheimer that people who grow their payos long and hide them behind their ears do look as if they're embarassed that they're performing a mitzvah, and that's a problem. Personally, I would ...

Per Rabbi Shraga Simmons at About.com: Question: Why do male Chasidic Jews have the long side curls in their hair? Answer: The Torah says, "You shall not round off the peyos of your head" (Leviticus 19:27). The word peyos refers to sideburns -- i.e. the hair in front of the ears that extends to underneath the cheekbone which is level with the ...

The Rambam (MT Ma'achalot Asurot 9:10) writes If the milk fell into the sauce or onto all the pieces and it was not known on which piece [the milk] fell he should stir the entire pot so that all its contents will be mixed [thoroughly]. If the flavor of milk [can be detected] in the entire pot, it is forbidden. If not, it is permitted. If a gentile ...

The table on page 86 (page 22 in the PDF) of Sheldon Epstein, Bernard Dickman, and Yonah Wilamowsky's paper "Parsha Management — Doubling, Halving, Accuracy"[1] is of the parashiyos and their lengths. According to the data in that table, we have: Counting each parasha separately, the deciles are 176 (100%), 148 (90%), 134 (80%), 122&...

One opinion brought on Bava Batra 75a says Adam was 100 cubits tall (approximately 150 ft).

The Rashbam explains that due to his strength he broke the wooden beds when he was younger and therefore they made a metal bed for him.

I would say its luminosity diminished. For most heavenly bodies, the angular size is too small to be resolved by the eye, but the brightness varies by orders of magnitude, so when we say some object is greater or lesser than another, we almost always mean luminosity. As another option, recall that the Moon was created by a collision of a Mars-sized object ...

Rabbi Natan Slifkin has an extensive presentation of all the different sides of the kezayis discussion here. He brings many opinions that actually do hold that the correct size of the kezayis is the actual size of an olive: R. Chaim of Volozhin (1749-1821) is widely revered as the father of the yeshivah world. Less known and certainly less popular in ...

See Rabbi Neustadt’s book which quotes the Mishnah Berurah 27: 15 to say that long hair is not a natural outgrowth of the body and therefore constitutes a chatzitzah between the head and the head-tefila. There are however lenient opinions. There is a long article by Rabbi Aryeh Lebowitz - this is his conclusion: While one who grows long hair cannot be ...

DoubleAA is correct that a Torah that is missing scribal traditions is still valid. However, if another Torah is available, the Torah inconsistent with tradition should not be used. (see Shevet HaLevi 4, Yoreh Deah 141) In addition, if the Torah was from a tradition that normally conforms with the small and large letters and, nevertheless, is consistently ...

It's not clear which practice you are looking to find the rational for, the larger or the smaller, but see the first tshuva in the Igros Moshe where he discusses Reb Shlomo Kluger's ruling to cover the majority of one's head. Reb Moshe says that it is a nice stringency to keep, but one is not obligated to be stringent, especially since most people are not ...

A mezuzah case is really only a way to extend the halachik doorpost such that there is no need to actually insert the klaf into the doorpost itself, so inherently, size should not be a halachik issue. Even with regard to the mezuzah klaf (parchment) itself, as long as it can fit in the appropriate place on the doorpost (bottom of top third, not within the ...

Rambam Parah Adumah 9:8 says that once the water has been mixed with the ashes, no further water can be added to further dilute the mixture. Once it has been made, an additional Parah Adumah is required to make more and add to the water. Thus, if any other water accidentally drops in, the entire mixture is pasul. When even the smallest amount of other ...

Pirke De’Rabbi Eliezer (ch. 24) gives the height dimension as being “seven(ty) mil”: רבי פנחס אומר לא היו שם אבנים לבנות את העיר ואת המגדל מה היו עושין היו מלבנים לבנים ושורפין אותן כיוצר חרש עד שבנו אותו גבוה שבעים מיל (Note: the Hebrew edition reads “seventy” while the English ed. by Gerald Friedlander, provided also at the above link to Sefaria, has “...
