Shashi P. Karna 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 Shashi P. Karna rather than just read about it. In short: Shashi P. Karna (born 1956) is a nanotechnology physicist who works for the United States Army Research Laboratory in Aberdeen, Maryland.

Key takeaways

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

Reference excerpt

Shashi P. Karna (born 1956) is a nanotechnology physicist who works for the United States Army Research Laboratory in Aberdeen, Maryland. In 2006, he was honored as a Fellow of the American Physical Society.

Educational background Karna, born in 1956 in Bihar, India, obtained his Ph.D. in 1983 and an M.Sc. in 1976 in chemistry from Banaras Hindu University. He holds a B.Sc. degree in mathematics, physics, and chemistry from Bhagalpur University in India, earned in 1973. Karna has a large publication record, with over 300 articles to his name, including technical papers, conference proceedings, reviews, and book chapters. He has co-edited several books, such as "DoD Applications of Nanomaterials."

Career Karna holds the position of senior research scientist (ST) specializing in nano-functional materials at the Army Research Laboratory, Weapons & Materials Research Directorate, located in Aberdeen Proving Ground, Maryland. Within his role, he led the ARL Nanoscience Strategic Technical Initiative from 2006-08 and been involved in various leadership positions. These include serving as the chair for the nanotechnology area at the Army Science Conference, the American Physical Society Symposium on Molecular Electronics, the American Chemical Society Symposium on Non-linear Optical Materials, and the Materials Research Society Symposium on Optical Materials, among others. Karna has contributed as a technical program committee member for the Institute of Electrical and Electronics Engineers (IEEE) NANO. He serves as the chair of the NATO Sensors and Electronics Technology Research Technical Group on "Smart Textiles" and holds advisory roles in academic institutions such as Michigan Technological University and the University at Buffalo. Karna is an adjunct professor at Michigan Technological University and Morgan State University.

Worked examples

Example 1 — a first encounter with Shashi P. Karna

Start with the simplest possible case. Write down what Shashi P. Karna 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 Shashi P. Karna 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 Shashi P. Karna 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 Shashi P. Karna

In research: Shashi P. Karna 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 Shashi P. Karna 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: Shashi P. Karna is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 20th-century Indian engineers, Fellows of the American Physical Society, so understanding it makes those chapters shorter.
In everyday life: Look for Shashi P. Karna 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.
