Reference excerpt

Natan Slifkin (also Nosson Slifkin) (Hebrew: נתן סליפקין; born 25 June 1975 in Manchester, England), popularly known as the "Zoo Rabbi", is a British born Israeli Orthodox Judaism rabbi, and the director of the Biblical Museum of Natural History in Beit Shemesh, Israel. Slifkin is best known for his interests in zoology, Judaism's relationship to evolution, Jewish and biblical history, and his writing on these topics.

Biography Slifkin was born and raised in Manchester, United Kingdom, where he studied at a local yeshiva called Yeshivas Shaarei Torah. He left in 1995 to continue his studies in the Medrash Shmuel yeshiva and Mir Yeshiva in Jerusalem, Israel. He was ordained at Ohr Somayach Institutions, where he taught Talmud and contemporary Judaism. He lives in Ramat Beit Shemesh, where he runs the Biblical Museum of Natural History. Slifkin has a master's degree in Judaic studies from the Lander Institute in Jerusalem, and a doctorate in Jewish history from Bar-Ilan University, completed in 2016. His dissertation was entitled: Rabbinic and Maskilic Encounters with Zoology in the Nineteenth Century.

Controversy Slifkin's books, which had "cautious references to evolutionary theory", led to a denunciation of his work by ultra-Orthodox authorities. One Rabbi who signed the ban, Elya Ber Wachtfogel, added that "even what is not heretical is expressed in a way only a heretic would speak". The ban led Slifkin's publisher to discontinue distribution of his books. Yashar Books, a smaller Jewish publisher, agreed to distribute them. Moment magazine quoted an anonymous rabbi who said: "The Slifkin ban is a huge break. It's a kind of power struggle, and those who didn't sign the ban are outraged right now. I'm talking about rabbis with long white beards who are furious about it... He's saying out loud what a lot of people have been talking about quietly all along. To those people, he's a kind of figurehead." Rabbis Aharon Feldman and Shlomo Miller wrote articles in defense of the ban, and Rabbi Moshe Meiselman gave three lectures on this topic at Toras Moshe. These defenses of the ban were themselves controversial, and Slifkin posted them all on his website, together with rebuttals written by various people. Meiselman requested that Slifkin remove the lectures from his website, but Slifkin did not. In 2013, Meiselman released a nearly 900-page book entitled "Torah, Chazal, and Science", which he stated "was in response to some recent controversies surrounding issues of Torah and science. A spate of books ... have attempted to introduce a radical new theology and proclaim it compatible with classic Jewish belief." Rabbi Chaim Malinowitz broke with his Haredi colleagues in not seeking a ban on Slifkin's books. On 5 October 2008, Slifkin published an essay entitled, In Defense of My Opponents, in which he says that there is a reasonable basis for a ban on his books in certain communities.

Worked examples

Example 1 — a first encounter with Natan Slifkin

Start with the simplest possible case. Write down what Natan Slifkin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Natan Slifkin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Natan Slifkin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Natan Slifkin

In research: Natan Slifkin appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Natan Slifkin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Natan Slifkin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1975 births, Bar-Ilan University alumni, British Modern Orthodox rabbis, so understanding it makes those chapters shorter.
In everyday life: Look for Natan Slifkin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
