Khalil Qureshi

Khalil Qureshi 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 Khalil Qureshi rather than just read about it. In short: Khalil Ahmad Qureshi (Urdu: خليل احمد قريشى; HI, SI), is a Pakistani physical chemist and the professor of physical chemistry at the Punjab University. He has published notable papers in nuclear physical chemistry in international scientific journals as well contributing in the advancement of the scientific applications of the civilian usage of the fuel cycle.

Key takeaways

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

Reference excerpt

Khalil Ahmad Qureshi (Urdu: خليل احمد قريشى; HI, SI), is a Pakistani physical chemist and the professor of physical chemistry at the Punjab University. He has published notable papers in nuclear physical chemistry in international scientific journals as well contributing in the advancement of the scientific applications of the civilian usage of the fuel cycle.

Early life and education A native of Lahore, Qureshi subsequently attended the Punjab University to study chemistry where he graduated with BSc in chemistry. For his higher studies, he went to United Kingdom to attend Imperial College London. He earned MSc in Chemical Technology and worked towards gaining the DIC in physical metallurgy. At the Imperial College, he joined the doctoral group led by Thomas West and David Craig. He earned his PhD in physical chemistry under the supervision of David Craig, writing his thesis on Physico-chemical studies of the vapour deposition of Al2O3, in 1972.

Career

Pakistan Atomic Energy Commission He briefly taught physical chemistry at the London University before moving to Pakistan. Upon his return, he joined the Pakistan Atomic Energy Commission (PAEC) and took the professorship of nuclear chemistry at the Pakistan Institute of Nuclear Science and Technology (PINSTECH). Subsequently, he joined the clandestine atomic bomb project's chemistry section led by fellow chemist Iqbal Hussain Qureshi. Munir Ahmad Khan, chairman PAEC, had him partially take over the "R-Labs" at PAEC to engage research in chemical explosives. Initially, the research was concentrated towards development of the HMX, a non-toxic explosive that was produced as a by-product of the RDX process. In the 1970s, he founded the Metallurgical Laboratory (ML) where he also moved majority of the staff to undertake research in metallurgy. He then led a team of chemists who supervised the physical conversion of UF6 into solid metal before coating and machining the metal. During this time, he also led the research on using chemical and metallurgical industrial techniques and reduction furnaces to produce metal from the Highly enriched uranium. Due to the sensitivity of the project and concerns of fellow theorist Dr. AQ Khan, the program was moved to KRL in the 1980s.

Research and science activism While at PAEC, Qureshi joined the chemistry department of Quaid-e-Azam University as an associate professor. In the 1990s, he joined the Punjab University to teach post-graduate course on physical chemistry. In the 2000s, he joined the Lahore University of Management Sciences's School of Science and Engineering as director of engineering and safety. Over the years, he became known for his strong scientific advocacy of peaceful usage of nuclear energy, safety, and security, following the Fukushima disaster. A member of Khwarizmi Science Society, he has lectured on safety issues regarded the nuclear power and topics in nuclear chemistry. He has also authored numerous articles on chemical safety and securities around the world in world's leading research journal. In 2011, he lectured on physical chemistry and spoke about how nuclear technology was being used currently and different ways of disposing nuclear waste at the Forman Christian College University in Lahore. He is the recipient of Pakistan's highest honours– the Hilal-i-Imtiaz bestowed in 2003 and the Sitara-e-Imtiaz bestowed in 1999 by the Government of Pakistan.

Worked examples

Example 1 — a first encounter with Khalil Qureshi

Start with the simplest possible case. Write down what Khalil Qureshi 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 Khalil Qureshi 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 Khalil Qureshi 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 Khalil Qureshi

In research
Khalil Qureshi 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 Khalil Qureshi 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
Khalil Qureshi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Lahore University of Management Sciences, Academic staff of Quaid-i-Azam University, Academic staff of the University of the Punjab, so understanding it makes those chapters shorter.
In everyday life
Look for Khalil Qureshi 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.
