Selig Brodetsky

Selig Brodetsky is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Selig Brodetsky rather than just read about it. In short: Selig Brodetsky (Hebrew: אשר זליג ברודצקי, romanized: Asher Zelig Brodetsky; 10 February 1888 – 18 May 1954) was an English mathematician, a member of the World Zionist Executive, the president of the Board of Deputies of British Jews, and the second president of the Hebrew University of Jerusalem.

Key takeaways

  • Selig Brodetsky belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Selig Brodetsky to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Selig Brodetsky from memory before moving on to harder problems.

Reference excerpt

Selig Brodetsky (Hebrew: אשר זליג ברודצקי, romanized: Asher Zelig Brodetsky; 10 February 1888 – 18 May 1954) was an English mathematician, a member of the World Zionist Executive, the president of the Board of Deputies of British Jews, and the second president of the Hebrew University of Jerusalem.

Background

Brodetsky was born in Olviopol (now Pervomaisk) in the Kherson Governorate of the Russian Empire (present-day Ukraine), the second of 13 children born to Akiva Brodetsky (the beadle of the local synagogue) and Adel (Prober). As a child, he witnessed the murder of his uncle in a pogrom. In 1894, the family followed Akiva to the East End of London, to where he had migrated a year earlier. Brodetsky attended the Jews' Free School, where he excelled at his studies. He was awarded a scholarship, which enabled him to attend the Central Foundation Boys' School of London and subsequently, in 1905, Trinity College, Cambridge. In 1908, he completed his studies with highest honours being Senior Wrangler, to the distress of the conservative press, which was forced to recognise that a son of immigrants surpassed all the local students. The Newton scholarship enabled him to study at Leipzig University where he was awarded a doctorate in 1913. His dissertation dealt with the gravitational field. In 1919, he married Manya Berenblum, whose family had recently emigrated from Belgium, where her father had been a diamond merchant in Antwerp. They had two children, Paul and Adele, in 1924 and 1927.

Academic career In 1914, Brodetsky was appointed a lecturer in applied mathematics at the University of Bristol. During the First World War he was employed as an advisor to the British company developing periscopes for submarines. In 1919, Brodetsky became a lecturer at the University of Leeds. Five years later he was appointed professor of applied mathematics at Leeds where he remained until 1948. Much of his work concerned aeronautics and mechanics of aeroplanes. He was the head of the mathematics department of the University of Leeds from 1946 to 1948. He was active in the Association of University Teachers, serving as president in 1935–1936. Brodetsky became the second president of the Hebrew University of Jerusalem in 1949, preceded by Sir Leon Simon, serving until 1952, and followed by Benjamin Mazar (1953 to 1961), at a time when the university was going through a rocky period, eventually having to abandon its campus on Mount Scopus. He attempted to overhaul the structure of the university but he soon became embroiled in bitter struggles with the University Senate, which interfered in his academic and bureaucratic work. Apparently, Brodetsky thought that he was going to take up a position similar to that of Vice-Chancellor of an English university but many in Jerusalem saw the position as essentially an honorary one, like the Chancellor of an English university. This struggle affected his health and in 1952 he decided to resign his post and return to England.

Worked examples

Example 1 — a first encounter with Selig Brodetsky

Start with the simplest possible case. Write down what Selig Brodetsky 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 Selig Brodetsky 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 Selig Brodetsky 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 Selig Brodetsky

In research
Selig Brodetsky 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 Selig Brodetsky 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
Selig Brodetsky is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1888 births, 1954 deaths, 20th-century English mathematicians, so understanding it makes those chapters shorter.
In everyday life
Look for Selig Brodetsky 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.
