Key takeaways

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

Reference excerpt

Ishrat Hussain Usmani (Urdu: عشرت حسین عثمانی) ‎ (15 April 1917 – 17 June 1992) NI, best known as I. H. Usmani, was a Pakistani atomic physicist, and later a public official who chaired the Pakistan Atomic Energy Commission (PAEC) from 1960 to 1971 as well as overseeing the establishment of the Space Research Commission. His career was mostly spent in the Government of Pakistan as a public policy official where he pushed for peaceful and commercial usage of the nuclear energy, and later worked on arms control with Ministry of Defense to become a party of Partial Nuclear Test Ban Treaty in 1963 before joining the International Atomic Energy Agency (IAEA) as the Chair of its Board of Governors. Usmani oversaw the nuclear power generation in Pakistan, working towards commissioning the nuclear power grid station in Karachi, and strengthened the role of the atomic energy commission at the United Nations.

Biography

Ishrat Hussain Usmani was born in Delhi in India on 15 April 1917. Usmani hailed from an educated, cultured, and gentry class, having completed his schooling in Aligarh. Usmani attended the St. Xavier's College in Bombay, and graduated with BSc with honors in physics from the Bombay University in 1936. His graduation from the Bombay University was noted in the local Indian press for being the first in the Presidency's Physics and Mathematics Group. Usmani continued his education in physics and went to attend the Aligarh Muslim University (AMU) where he attained his MSc in physics. Usmani went to the United Kingdom to attend the doctoral program in physics at the Imperial College in London, to work under George Paget Thomson on electron diffraction. At Imperial College, Usmani qualified for Diploma of Imperial College (DIC). Usmani later joined Niels Bohr at the London University to continue his investigation on the electron diffraction through crystallization, and submitted his thesis under the supervision of Dr. Bohr, titled: "A study of the growth of compound crystals by electron diffraction" in 1939. His early work and investigation was based on the crystallization, lattice arrangement, and atomic properties of Uranium. In 1941, Usmani was conferred with PhD in atomic physics, just aged 23, and subsequently returned to India in 1942, where he qualified for the examination for the Indian Civil Service (ICS). Rather than seeking teaching career in physics at the Indian universities, Usmani joined the Indian Civil Service in a view of seeking an employment opportunity with the Indian government, and served as an ICS officer in Madras Presidency from 1942 to 1947.

Career in Government of Pakistan

Pakistan Atomic Energy Commission

After the partition of India in 1947 by the United Kingdom, Usmani, who had decided to never teach physics at the university, chose to continue his public service with the Government of Pakistan, serving in various federal agencies including his role as Chief Controller of Imports and Exports with the Ministry of Finance. He built up his prestige in the federal government and was noted by President Ayub Khan for his doctorate in physics who could advise the federal government on scientific matters, especially ways of electricity generation in Pakistan besides hydroelectricity. In 1959, Zulfikar Ali Bhutto, then-Minister of Energy in the Ayub administration, lobbied to appoint Usmani to the corporate administration of the Pakistan Atomic Energy Commission that was being chaired by Dr. Nazir Ahmed, and eventually took its chairmanship in 1960. Under his chairmanship, Usmani engaged the PAEC towards the peaceful usage of nuclear energy for greater industrial output, and supported the American initiatives for Atoms for Peace. Usmani launched the PAEC scholarship program that selected 50 of the brightest students in physical science, mathematics, and engineering to pursue higher education in the United States, namely attending the University of North Carolina, Massachusetts Institute of Technology, Pennsylvania State University, and the University of Michigan. Funding of the students was not restricted to study in United States but also in United Kingdom and Canada. In addition, Usmani placed a request to his American friends, Dr. Alvin Martin Weinberg and Dr. Robert Charpi, to allow Pakistan's foreign exchange students to carry out their research at Oak Ridge National Laboratory (ORNL) and Argonne National Laboratory (ANL), asking them to arrange an on-the-job training program at their sites. In 1961, Usmani commissioned the American firms, the Gibbs and Hill and Internuclear Company, to conduct feasibility and standard study for the establishment of nuclear power plants, whose recommendations became the standard for the PAEC's construction of nuclear power industry in the country. Usmani also provided his support to Planning Commission and Geological Survey (GSP) to independently conduct surveys for the construction of the power plant, and engaged in negotiation with the International Atomic Energy Agency (IAEA) for financial and further support for the power plant to be constructed in Karachi, known as the Karachi Nuclear Power Plant (KANUPP). In 1967, Usmani played a pivotal role in securing the federal funding for establishing the Institute of Nuclear Science and Technology near Islamabad– a visionary national laboratory site functioning under Dr. Abdus Salam, a theoretical physicist. He helped negotiate the establishment of the Institute by speaking with the American architect, Edward Durrell Stone, and oversaw the final construction of the Institute of Nuclear Science and Technology by 1967–68. Usmani also took great interest in space exploration by helping Dr. Abdus Salam establishing the Space Research Commission in 1961, serving as its deputy director, and sought NASA's helped in his nation's first rocket launching program.

Worked examples

Example 1 — a first encounter with Ishrat Hussain Usmani

Start with the simplest possible case. Write down what Ishrat Hussain Usmani claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Ishrat Hussain Usmani 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 Ishrat Hussain Usmani 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 Ishrat Hussain Usmani

In research
Ishrat Hussain Usmani appears in physics 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 Ishrat Hussain Usmani 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
Ishrat Hussain Usmani is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1917 births, 1992 deaths, Aligarh Muslim University alumni, so understanding it makes those chapters shorter.
In everyday life
Look for Ishrat Hussain Usmani 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.
