Mohammad Reza Darafsheh 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 Mohammad Reza Darafsheh rather than just read about it. In short: Mohammad Reza Darafsheh (born 31 August 1950) is an Iranian Mathematician and Professor of Mathematics at the University of Tehran, and a member of the executive committee of the Iranian Mathematical Society. He received a B.Sc. in Mathematics from the University of Tehran with first rank in 1974 and M.Sc. and Ph.D. degrees from University of Birmingham in 1975 and 1978 respectively under the supervision of Donald L…

Key takeaways

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

Reference excerpt

Mohammad Reza Darafsheh (born 31 August 1950) is an Iranian Mathematician and Professor of Mathematics at the University of Tehran, and a member of the executive committee of the Iranian Mathematical Society. He received a B.Sc. in Mathematics from the University of Tehran with first rank in 1974 and M.Sc. and Ph.D. degrees from University of Birmingham in 1975 and 1978 respectively under the supervision of Donald Livingston. His dissertation was titled "On some Subgroups of C_1." He has been a faculty member at the Shahid Chamran University of Ahvaz from 1978 to 1989, and from 1989 to present at the University of Tehran, where he chaired the mathematics department from 1995 to 1999 he has advised 33 Ph.D. students. His research area includes the representations and characters of finite groups, symmetry class of tensors, Thomson's conjecture, characterization of simple groups by the set of elements order. He has solved the Feit's conjecture on the p-Steinberg characters of finite groups. He has contributed to finding the character tables of linear groups. He has authored the books "An introduction to group theory", "Linear groups", and a 3 volume book titled "Algebra" which was included in "Eighty Treasures" in 2008 as part of the 80th anniversary of University of Tehran's establishment. He was awarded the Abdus-Salam prize in Mathematics by International Centre for Theoretical Physics in 1990, and the Khwarizmi International Award in 1997.

Worked examples

Example 1 — a first encounter with Mohammad Reza Darafsheh

Start with the simplest possible case. Write down what Mohammad Reza Darafsheh 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 Mohammad Reza Darafsheh 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 Mohammad Reza Darafsheh 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 Mohammad Reza Darafsheh

In research: Mohammad Reza Darafsheh 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 Mohammad Reza Darafsheh 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: Mohammad Reza Darafsheh is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, 20th-century Iranian mathematicians, 21st-century Iranian mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Mohammad Reza Darafsheh 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.
