Opendra Narayan

Opendra Narayan 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 Opendra Narayan rather than just read about it. In short: Opendra "Bill" Narayan (November 28, 1936 – December 24, 2007) was an HIV/AIDS researcher at the Johns Hopkins School of Medicine and the University of Kansas Medical Center. A veterinarian, Narayan researched animal models of HIV.

Key takeaways

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

Reference excerpt

Opendra "Bill" Narayan (November 28, 1936 – December 24, 2007) was an HIV/AIDS researcher at the Johns Hopkins School of Medicine and the University of Kansas Medical Center. A veterinarian, Narayan researched animal models of HIV. His focus on finding a vaccine for retroviral infection had some success against a monkey retrovirus, SIV, and he is best known for engineering a type of HIV that could cause AIDS-like disease in monkeys.

Research

Education and training Born in Guyana, Narayan earned his doctorate in veterinary medicine (DVM) from the University of Toronto in 1963. In 1970, he received a PhD in virology from the University of Guelph. Narayan trained as a postdoctoral researcher with renowned neurovirologist Richard T. Johnson at the Johns Hopkins School of Medicine beginning in 1972.

Career Narayan remained at Johns Hopkins as a faculty member and became director of the Retrovirus Biology Laboratory. Narayan left Johns Hopkins in 1992. He moved to the University of Kansas, where he was named Distinguished Professor and director of the Marion Merrell Dow Laboratory of Viral Pathogenesis. Narayan remained at Kansas until his death in 2007. While at the University of Kansas, Narayan received nearly $50 million in grants, including almost $20 million from the National Institutes of Health.

Honors Narayan was presented with the Pioneer in NeuroVirology Award by the International Society for NeuroVirology (ISNV) at the 7th International Symposium on NeuroVirology held in Philadelphia, Pennsylvania, in 2006.

Controversy Simon Watney has described Narayan's explanation of the spread of HIV/AIDS among gay males as 'uniquely disgusting' when he quotes Narayan's statement that:

the active sexual partner injects infected semen into the anus of the passive partner [...] These people have sex twenty to thirty times a night [...] A man comes along and goes from anus to anus and in a single night will act as a mosquito transferring infected cells on his penis. When this is practiced for a year, with a man having three thousand sexual intercourses', one can readily understand this massive epidemic that is currently upon us.

Worked examples

Example 1 — a first encounter with Opendra Narayan

Start with the simplest possible case. Write down what Opendra Narayan 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 Opendra Narayan 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 Opendra Narayan 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 Opendra Narayan

In research: Opendra Narayan 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 Opendra Narayan 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: Opendra Narayan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 2007 deaths, American veterinarians, so understanding it makes those chapters shorter.
In everyday life: Look for Opendra Narayan 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.
