Reference excerpt

Qazi Motahar Hossain (30 July 1897 – 9 October 1981) was a Bangladeshi writer, scientist, statistician, chess player, and journalist. Hossain was a pioneer educationalist of Bangladesh. He did original research in statistics and pioneered its education in Bangladesh both as a faculty and administrator. As one of the early faculties of University of Dhaka, he was vigorously active in the cultural circles that grew around it. As a Dhaka-centric literary figure in late British India, a period marked by communality and religious sentiment, Hossain and his literary group Shikha distinguished themselves as proponents of communal harmony and rationalism. He was among the sceptical intellectuals who warned of the consequences of the short-lived state of Pakistan. On several occasions, he vocally criticized Pakistani government policies, most importantly on the state language question.

Early life and education Hossain was born into the aristocratic Qazi family of Bagmara to Qazi Gawharuddin and Tasirunnesa, at his maternal home, Lakshmipur village, in Kushtia District, in the then British India. His family had arrived in Mughal Bengal from Western Asia during the reign of Shah Jahangir, his ancestors were designated as the judges of the court of Delhi, hence the name of the clan is "Qazi." He passed his childhood years at his father's village Bagmara in Rajbari, a district adjacent to Kushtia. He received his earliest education from his father and from the village primary school. Hossain entered Kushtia High School, distant from his home, for Secondary studies. During his time in Kushtia, Hossain, coming from a household with lesser income, supported himself by various scholarships, lodged at nearby homes as house tutors and later settled at a hostel. Among the teachers, he specially later recalled Jyotindranath Roy and Jatindra Mohan Biswas. During his years at the school, Jyotindranath Roy, an accomplished teacher of Mathematics and Sciences, laid Hossain's foundation in algebra, geometry, conic section and mechanics. Mr. Roy, recognizing Hossain's interest in mathematics, introduced the mechanics course solely for him. In 1915, Hossain passed Entrance from there. After passing entrance, already his interest in Science and Mathematics confirmed, Hossain went to Presidency College in Kolkata for I Sc. There he was highly impressed by eminent teachers like Praphulla Chandra Ghosh (English), Mr. Sterling (English), Prafulla Chandra Roy (chemistry). He, however, transferred himself to Rajshahi College, from where he completed his I Sc in 1917, in the middle of the academic year. In his college years, beside his studies, Hossain excelled in sports like football, tennis, etc. In 1917, Hossain arrived in Dhaka, his first visit to the town where he would spend rest of his life, and got admitted to Dhaka College for his B A in Mathematics and Physics. Here he found W. A. Jenkins (Physics), Wrangler Bhupati Mohan Sen (Mathematics), Bankim Das Banerjee (Mathematics) and others as teachers. In 1919, he was awarded BA (honors) from this college. Hossain passed M A in physics in 1921 from the same college. In 1921, the University of Dhaka, was founded, where Hossain would spend the rest of his life, serving various roles; that year, Hossain, still a student of M. A. at Dhaka College, preparing for final exams, joined the newly founded university as demonstrator (junior lecturer) of physics. The same year, prominent physicist Satyendra Nath Bose joined the university as a reader of physics; Hossain got intimate with Bose as colleague and Bose also quickly recognized Hossain's genius. During his preparation of M A examination, Hossain recalled, Bose provided critical inputs; their co-operation would continue in later years and Bose would leave formative influence on Hossain's career. Bose, now head of the department of physics, encouraged Hossain to pursue higher study in statistics, a subject only getting its foothold in India, under premier Indian statistician, Prasanta Chandra Mahalanobis. Hossain accepted the offer and travelled to Calcutta, Bose himself accompanying him to introduce Hossain to Mahalanobis, to study at Mahalanobis's newly founded Indian Statistical Institute. Hossain returned to Dhaka, in 1938, with a diploma in statistics from Indian Statistical Institute and pioneered the subject in Bangladesh. Upon returning from Indian Statistical Institute, Hossain concentrated on statistics, both as an educator and a self-taught researcher at University of Dhaka. While at Indian Statistical Institute, Hossain learned about balanced incomplete block design, and then endeavoured a thesis, under informal supervision of Bose, who was working on related topics then: counting possibility of certain balanced incomplete block design configurations by trial method. He received a doctorate for this work.

Career

Teaching Qazi Motahar Hossain joined the newly established University of Dhaka in 1921, still a student of M A at Dhaka College, as demonstrator of physics. Two years later, in 1923, he was promoted to assistant-lecturer. Spearheaded by Hossain, University of Dhaka introduced Masters in Statistics, in 1948; Hossain proudly reminisced that University of Dhaka preceded the much older Presidency College Calcutta in this particular course. He retired from Dhaka University in 1961. Hossain founded the Institute of Statistical Research and Training (ISRT), University of Dhaka, in 1964, and served as founder-director until 1966. University of Dhaka appointed him Professor Emeritus in 1969. In 1975, after the liberation of Bangladesh, he was appointed the National Professor of Bangladesh, the position he decorated until his death, in 1981. He was a founder fellow of Bangladesh Academy of Sciences.

Worked examples

Example 1 — a first encounter with Qazi Motahar Hossain

Start with the simplest possible case. Write down what Qazi Motahar Hossain claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Qazi Motahar Hossain 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 Qazi Motahar Hossain 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 Qazi Motahar Hossain

In research
Qazi Motahar Hossain appears in mathematics 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 Qazi Motahar Hossain 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
Qazi Motahar Hossain is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1897 births, 1981 deaths, 20th-century Bangladeshi chess players, so understanding it makes those chapters shorter.
In everyday life
Look for Qazi Motahar Hossain 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.
