K. Sivan

K. Sivan is a engineering 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 K. Sivan rather than just read about it. In short: Kailasavadivu Sivan (born 14 April 1957) is an Indian aerospace engineer who served as the secretary of the Department of Space and chairman of ISRO and Space Commission. He has previously served as the director of the Vikram Sarabhai Space Center and the Liquid Propulsion Systems Centre.

Key takeaways

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

Reference excerpt

Kailasavadivu Sivan (born 14 April 1957) is an Indian aerospace engineer who served as the secretary of the Department of Space and chairman of ISRO and Space Commission. He has previously served as the director of the Vikram Sarabhai Space Center and the Liquid Propulsion Systems Centre.

Early life Sivan was born in Sarakkalvilai, near Nagercoil in Kanyakumari district of Tamil Nadu in India. He is the son of a mango farmer (his father Kailasa Vadivu) and his mother Chellam.

Education Sivan studied in a Tamil languagel government school in Sarakkalvilai Village and later in Vallan Kumaran Vilai, in Kanyakumari district. He is the first graduate from his family. Sivan graduated with a bachelor's degree in aeronautical engineering from Madras Institute of Technology in 1980. He then got a master's degree in aerospace engineering from the Indian Institute of Science in 1982, and started working at ISRO. He earned a doctorate in aerospace engineering from the Indian Institute of Technology, Bombay in 2006. He is a Fellow of the Indian National Academy of Engineering, the Aeronautical Society of India and the Systems Society of India. He was conferred Doctor of Science (Honoris Causa) from Sathyabama University, Chennai in April 2014.

Career Sivan worked on the design and development of launch vehicles for Indian Space Research Organisation (ISRO). Sivan joined ISRO in 1982 to participate on the Polar Satellite Launch Vehicle Project. Sivan played a major role in reviving the Geosynchronous Satellite Launch Vehicle programme. The 6D trajectory simulation software SITARA was developed under the guidance of Sivan. He was appointed the director of ISRO's Liquid Propulsion Systems Centre on 2 July 2014. On 1 June 2015, he became the director of Vikram Sarabhai Space Centre. Sivan was appointed the chief of ISRO in January 2018 and he assumed office on 15 January. Under his chairmanship, ISRO launched Chandrayaan-2, their second mission to the Moon, on 22 July 2019, of which the Vikram lander and Pragyan rover crashed; the orbiter was not affected and is still orbiting the Moon as of September 2023. On 30 December 2020, his chairmanship was extended by a year to January 2022. His earlier tenure was up to January 2021. On 25 January 2021, the Central Vigilance Commission (CVC) has registered a complaint against K Sivan over allegations of irregularities in recruiting his son in ISRO’s Liquid Propulsion Systems Centre (LPSC) in Valiamala, Thiruvananthapuram, bypassing hiring standards. Sivan has been appointed the chairman of the Board of Governors at the Indian Institute of Technology, Indore. He will replace Deepak B P, whose term ended on 21 August 2023.

Worked examples

Example 1 — a first encounter with K. Sivan

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

In research: K. Sivan appears in engineering 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 K. Sivan 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: K. Sivan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1958 births, 20th-century Indian engineers, Engineers from Tamil Nadu, so understanding it makes those chapters shorter.
In everyday life: Look for K. Sivan 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.
