P. Karthe

P. Karthe is a biology 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 P. Karthe rather than just read about it. In short: Ponnuraj Karthe is an Indian structural biologist and a professor and the head of the Department of Crystallography and Biophysics of the University of Madras. He is known for his research in the fields of structural biology and drug designing.

Key takeaways

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

Reference excerpt

Ponnuraj Karthe is an Indian structural biologist and a professor and the head of the Department of Crystallography and Biophysics of the University of Madras. He is known for his research in the fields of structural biology and drug designing. His studies have been documented by way of a number of articles and Google Scholar, an online repository of scientific articles has listed 46 of them. Besides, he has contributed chapters to books edited by others and has delivered invited speeches at many seminars which include the Workshop on Advances in Computer Aided Drug Design held in August 2010 at the University of Madras. He was a member of the national organizing committee of the Annual Conference of Indian Biophysical Society - Molecular Architecture, Dynamics and Assem, organized by Saha Institute of Nuclear Physics and serves as a member of the national committee of the International Union for Pure and Applied Biophysics (IUPAB) as well as the executive council of the Bioinformatics and Drug Discovery Society (BIDDS), a non governmental organization promoting dissemination of knowledge in the fields of bioinformatics, biological sciences and other life sciences. The Department of Biotechnology of the Government of India awarded him the National Bioscience Award for Career Development, one of the highest Indian science awards, for his contributions to biosciences, in 2010.

Worked examples

Example 1 — a first encounter with P. Karthe

Start with the simplest possible case. Write down what P. Karthe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 P. Karthe 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 P. Karthe 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 P. Karthe

In research: P. Karthe appears in biology 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 P. Karthe 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: P. Karthe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the University of Madras, Indian medical researchers, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for P. Karthe 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.
