J. N. Srivastava

J. N. Srivastava is a mathematics 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 J. N. Srivastava rather than just read about it. In short: Jagdish Narain Srivastava (1933–2010) was an Indian-born mathematician, statistician and a professor at Colorado State University. Srivastava is known for the research in the area of Design of experiments, Multivariate analysis and Combinatorial mathematics.

Key takeaways

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

Reference excerpt

Jagdish Narain Srivastava (1933–2010) was an Indian-born mathematician, statistician and a professor at Colorado State University. Srivastava is known for the research in the area of Design of experiments, Multivariate analysis and Combinatorial mathematics. Srivastava was a Fellow of Institute of Mathematical Statistics. J. N. Srivastava received a Ph.D. in 1962 from the University of North Carolina at Chapel Hill. Prof. R. C. Bose was Srivastava's advisor. He joined Colorado State University in 1966. He was known for his contributions in design of experiments as well as in multivariate analysis, survey sampling, reliability, coding theory, combinatorial theory, and other areas of statistics and mathematics. Srivastava code was invented by him. Gödel's incompleteness theorems inspired him to recognize the limitations of science. He slowly turned toward spirituality and studied all the major religions of the world. This led him to obtain his 1991 joint appointment in the philosophy department of CSU. After his retirement, he moved to California. He died on 18 November 2010. He is survived by his wife of sixty years Usha, son Arvind, daughter Gita and son-in-law Roy; son Ashok, daughter-in-law Lynn and granddaughter Leela.

Worked examples

Example 1 — a first encounter with J. N. Srivastava

Start with the simplest possible case. Write down what J. N. Srivastava claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 J. N. Srivastava 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 J. N. Srivastava 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 J. N. Srivastava

In research: J. N. Srivastava appears in mathematics 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 J. N. Srivastava 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: J. N. Srivastava is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 2010 deaths, 20th-century Indian statisticians, so understanding it makes those chapters shorter.
In everyday life: Look for J. N. Srivastava 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.
