Vernon Cooray

Vernon Cooray is a science 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 Vernon Cooray rather than just read about it. In short: Vernon Cooray is a Sri Lankan scientist who is an emeritus professor at the Department of Electrical Engineering at Uppsala University, Sweden. As a scientist he has concentrated on solving both physics and engineering problems related to lightning physics, lightning protection and physics of electrical discharges.

Key takeaways

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

Reference excerpt

Vernon Cooray is a Sri Lankan scientist who is an emeritus professor at the Department of Electrical Engineering at Uppsala University, Sweden. As a scientist he has concentrated on solving both physics and engineering problems related to lightning physics, lightning protection and physics of electrical discharges. This research work has resulted in more than 600 research publications. He was the Ph.D. thesis supervisor of more than thirty researchers, both at Uppsala and foreign universities, who are now actively engaged in lightning research and lightning protection in different parts of the world.

Early life and career In 2014, he was elected as the president of the International Conference on Lightning Protection (ICLP) for a period of six years. ICLP is considered as the most prestigious conference in the world that addresses the problems related to lightning physics and lightning protection and attended by lightning researchers and engineers from all over the world. From 2000 to 2017, he was the professor responsible for the research and Ph.D. studies in the field of atmospheric electrical discharges at Uppsala University. Vernon Cooray has also contributed to educate the general public on lightning and lightning protection through newspapers, radio and television. Vernon Cooray has edited three books and authored two books on lightning physics and lightning protection.

Research He is the first scientist to show that the basic foundation of all engineering return stroke models are the same even though they are expressed in different mathematical formulations. He is also the first scientist to resolve one of the controversies that existed in 1980s between the EMC engineers and Power engineers related to the theories of interaction of lightning electromagnetic fields with power lines by showing that a model developed by Prof. Sune Rusck, and used frequently by power engineers, is identical to the model developed by Agrawal et al., frequently used by EMC engineers. He and his collaborators were the first group of scientists to show that lightning cloud flashes are as efficient as lightning ground flashes in generating nitrogen oxides. He together with Prof. Marcos Rubinstein developed the Cooray-Rubinstein approximation which is frequently used in analysing the voltages induced in power lines by lightning. Vernon Cooray and Marley Becerra developed the lightning interaction simulation program SLIM that can be used to predict the location of lightning strikes to structures. He together with Dr. Gerald Cooray illustrated a connection between classical electromagnetic fields and time energy uncertainty principle.

Awards He has been awarded the Doctor of Science (D.Sc.) honorary degree from University of Colombo in Sri Lanka, the IEEE fellow membership, the Karl Berger award from the international scientific committee of ICLP, and the best book award from the Atmospheric Science Librarians International (ASLI).

Worked examples

Example 1 — a first encounter with Vernon Cooray

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

In research: Vernon Cooray appears in science 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 Vernon Cooray 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: Vernon Cooray is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, Fellows of the IEEE, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Vernon Cooray 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.
