Micha Sharir

Micha Sharir 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 Micha Sharir rather than just read about it. In short: Micha Sharir (Hebrew: מיכה שריר; born 8 June 1950 in Tel Aviv, Israel) is an Israeli mathematician and computer scientist. He is a professor at Tel Aviv University, notable for his contributions to computational geometry and combinatorial geometry, having authored hundreds of papers.

Key takeaways

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

Reference excerpt

Micha Sharir (Hebrew: מיכה שריר; born 8 June 1950 in Tel Aviv, Israel) is an Israeli mathematician and computer scientist. He is a professor at Tel Aviv University, notable for his contributions to computational geometry and combinatorial geometry, having authored hundreds of papers.

Biography Sharir was born in Tel Aviv in 1950. As a secondary school student he won the first place in the youth mathematics olympics of the Weizmann Institute of Science and Grossman Award from the Technion. In 1970, he completed his undergraduate studies and then served in unit 8200 of the Israel Defense Forces, during his service he was involved in a research team which won the 1975 Israel Defense Prize. In 1976, Sharir completed his doctoral (Ph.D.) studies in pure mathematics under the supervision of Aldo Lazar in Tel Aviv University. Then he began his postdoctoral studies at the Courant Institute of New York University, where he worked with Jack Schwartz. In 1980, he joined the faculty of Tel Aviv University, where he holds the Isaias Nizri Chair in Computational Geometry and Robotics as of 2020. He is also a visiting research professor at the Courant Institute, where he has been the deputy head of the Robotics Lab (1985–89). At Tel Aviv University, he has served as head of the computer science department (twice), head of the school of mathematics (1997–99), and is one of the cofounders of the Minerva Center for Geometry. Sharir was named a Fellow of the Association for Computing Machinery in 1997. He received an honorary doctorate from Utrecht University in 1996, the Feher Foundation Prize in Computer Science from the Jerusalem Institute for Israel Studies in 1999, the Landau Prize for Science and Research in 2002, and the million-dollar The EMET Prize for Art, Science and Culture in the Exact Sciences from the A.M.N. Foundation in 2007. Sharir is an Institute for Scientific Information, ISI Highly Cited researcher. He was involved with developing international standards in programming and informatics, as a member of the International Federation for Information Processing (IFIP) IFIP Working Group 2.1 on Algorithmic Languages and Calculi, which specified, maintains, and supports the programming languages ALGOL 60 and ALGOL 68.

Worked examples

Example 1 — a first encounter with Micha Sharir

Start with the simplest possible case. Write down what Micha Sharir 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 Micha Sharir 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 Micha Sharir 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 Micha Sharir

In research: Micha Sharir 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 Micha Sharir 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: Micha Sharir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, Academic staff of Tel Aviv University, Fellows of the Association for Computing Machinery, so understanding it makes those chapters shorter.
In everyday life: Look for Micha Sharir 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.
