I think their main point is not that the theory in all its details is identical to the Jewish tradition. For thousands of years, conventional western wisdom was based on the Aristotelian assumption of kadmuth ha'olam - that the universe always was as it is. The modern discoveries of physics which talk about a finite point in time before which human ...

The most straightforward reading -- I'd say this is based on the Talmud -- is that it's miraculous. And only works if the husband has been behaving himself too, and if this is a rare and shocking event. Hence it stopped working sometime during the Second Temple period. (In effect, normally if a husband warned his wife not to hang around with Billy Bob, and ...

I don't know if they address this concern particularly in terms of the expense. However, the knowledge that murex indigo is chemically identical to plant-based indigo is something knowable only in the 20th and 21st century, when we know about atoms, molecules, and chemicals. If plant-based indigo failed the gemara's test for fastness, and this was just a ...

You are probably looking for Challenge: Torah Views on Science and Its Problems, edited by R' Aryeh Carmell and Dr. Cyril Domb in association with the Association of Orthodox Jewish Scientists, published by Feldheim in 1976 (1st edition) and 1988 (2nd edition).

I'm not sure what you mean by "the Torah" knowing. The Torah was given from Hashem, and He is obviously aware of how He made the world. The Torah won't be saying something that is not true. Therefore, it can't be saying something that is the opposite of true scientific discovery. As far as if all scientific facts of the universe is in the Torah, we find the ...

As far as I know (from experience around the industry) this is a generally recognized phenomena. Consider Flavor Scalping, where the packaging absorbs the flavor of the contents and vis-versa. Now, I'm sure in the details the Halacha is way more strict in many cases beyond a scientific understanding of the situation, but the basic notion is certainly well ...

Even assuming the 7 days are symbolic/conceptual as opposed to literal does not mean that their commemoration cannot be with a literal 7th day. Indeed, if one loses track of the days of the week (e.g. at sea) he keeps every seventh day anyway. (There are many mitzvot where something concrete represents something conceptual, e.g. teffilin, sukka, korbanot, ...

Actually, a number of meforshim explain that it starts with the the general and then gets specific. Thus the first verse (Bereishis) refers to the entire process (all seven days). The Art Scroll Chumash states "In the beginning of Hashem's Creating" This phrase is commonly rendered In the beginning Hashem created, which would indicate that the ...

There's a story in the Talmud - Shabbat 31a - about a guy who tried (unsuccessfully, as it turned out) to win a bet by provoking Hillel to anger. He posed three questions about phenotypic variations in certain human populations: מפני מה ראשיהן של בבליים סגלגלות א"ל בני שאלה גדולה שאלת מפני שאין להם חיות פקחות [He asked,] "What is the reason that the ...

The product of adulterous relations between a married Jewish woman and a Jewish man who is not her husband is a mamzer. Genetics shchmenetics. (The more common question is the converse -- married woman gets donor sperm from a Jewish man who's not her husband. Rabbis Moshe Feinstein and Shlomo Zalman Auerbach ruled that's not a mamzer as there were no ...

The Rambam actually says something which is somewhat the opposite - you could be an apikorus for refusing to accept that the literal interpretation is not what the Torah means. The Rambam's third principle of faith is believing that Hashem does not have a body. The Rambam in Moreh Nevochim 2:25 actually says that he would have had an easier time ...

Heliocentrism or geocentrism or whatever is entirely irrelevant to halachah; at most there is a question whether certain Biblical verses or aggadic comments correspond to (current scientific understanding of) the universe as it is, or reflect the way we perceive the world, similar to the continued use of the English words “sunrise” & “sunset”. That ...

Torah and religion teach of the world as it is (assuming that we know to understand the teaching correctly) while science deals with the world as we see it. There cannot be any religious problem to speak of the world as God has shown it to us, as long as we recognize that our perception of the world should not be taken as the ultimate true description of the ...

This requirement is stated in the Tosefta and Meseches Tzitzith Tosefta Menachoth 9:16 "תכלת אין כשרה אלא מן החלזון הביא שלא מן החלזון פסולה." Tekheleth is only valid from the חלזון ; if one used a dye not made from the חלזון it is invalid.” מסכת ציצית פרק א הלכה י שאין צובעין תכלת אלא בחלזון. We only dye תכלת with a חלזון from: ...

Surprisingly enough, proteins (such as those found in food, especially in meet) have a great affinity in binding to steel surface layer. On top of this, proteins also tend to affect the chemical composition of the stainless steel surface, by selectively releasing metal ions from the stainless steel alloy. https://en.wikipedia.org/wiki/Protein_adsorption ...

I once heard HaRav Aharon Lopiansky quote the following from HaRav Aharon Lichtenstein Zt"l: המתחתן עם הדור הזה מתאלמן מן הדור הבא or, in less-poetic English, One who marries this generation becomes widowed from the next generation. In other words, Creation was something that happened a rather long time ago, it's cryptic and unclear exactly what ...

According to the Maharal, amongst others, literal readings of non-Halachik Talmudic or Midrashic statements are incorrect and indeed Chazal are not discussing natural phenomena at all. Rather, they are discussing fundamental metaphysical realities and theology at a level that requires a deeper understanding of their language and philosophy (See, e.g., ...

Logically, he answered that the question itself does not apply (under the circumstances in which it was asked). Had there been a legitimate question, then he might have gone into the reasoning behind it. However, since the "evidence" did not apply, then he did not have to go any farther than it did. Note that he did not say that it was not a good question or ...

Going back a step... The key to understanding the first section of the Kuzari is to forget all the more contemporary talk about "the Kuzari Principle" and realize that Rabbi Yehudah haLevi's (Rihal's) thesis is to deprecate the value of the entire concept of philosophical proof. This is why the book starts with the king having a prophetic dream, "Your ...

The Medrash in Lech Lecha said that even if all the learned get together they won't be able to breath life into a gnat. This doesn't object to being able manipulate, or perhaps even create, body parts. But it does state that humans can't produce real, functioning life.

There is a letter from Rabbi Hirsch found here http://www.mesora.org/hirsch.html now printed in the ninth section of his collected writings. This letter deals with statements of Chazzal which deal with their view of sciences and seem bizarre to the modern mind. Here's two excerpts: Sages of Torah, not Masters of Science In my opinion, the first ...

The point about the "Big Bang" is that given a point of creation, there must have been a creator. Thus, if the Big Bang was not the point of creation of the universe, then whatever came before had to have been created. Or perhaps whatever came "before" that or ... Once scientists dropped the "eternal universe" theory for some starting point, They eventually ...

Shulchan Aruch introduces the laws of cross-breeding/cross-grafting species by saying that "two plants or animals may appear to be different, but are actually the same species but grew differently because of conditions or locations."

Possibly the point of the upward flow was to make the pillar of water visible to all the inhabitants of Canaan. This is similar to requirement that the Jews leave Egypt during the day to demonstrate the powerlessness of the Egyptians.

According to הרב מאיר הלוי הלמן - לבוש הארון (modern English sefer on Techeiles), on page 21: The color of murex dye was commonly known as “Tyrian Purple”, as the city of Tyre (today in Lebanon) was the leading center for purple dye production. Murex dye had “great brilliance and fastness in comparison with other known dye”. These qualities, as ...

I'm not aware of any references in the Chumash itself, but the only two passages in the entire Tana'kh that may be relevant to your question, to my knowledge, are (JPS): Yeshayahu 40:22 "It is He that sitteth above the circle of the earth." (Rashi links this verse to 44:13, which speaks of a carpenter using a "compass") Iyov 26:7 "He stretcheth out the ...

The mitzvah of blowing shofar is m'Doraita, meaning from the written Torah. (VaYikra 23:24 and VaYikra 25:9) This has the implication that in questions regarding it's fulfillment, one should be stringent. In other words, one should be stringent, for example, that what you are blowing is in fact a kosher shofar. There are requirements on the horn itself and ...
