Sudan: Mahjoub Obeid Taha, an Exceptional Scientific Genius


A born scientist, Professor Mahjoub Obied Taha, is known to have introduced a number of scientific inventions in the field of physics and mathematics.

He developed, the first relativistic generalization, developed the Taha's method for general polynomial 0-1, developed the Taha sum rule, discovered a new sum rule for the reaction between protons and electrons addition to other referential published works in international scientific periodicals and journals.

Due to his value-added scientific contributions, the American space agency NASA and several international universities sought his service. Mahjoub was twice offered a job by NASA, while he was working at the Institute for Advanced Study in Princeton, USA, which he politely declined. A third offer was made to him by NASA, as related by his son Obeid, where NASA left the salary column free for his late father to state his preferred salary, but he declined that third offer as well and preferred to come back and work as professor of physics at the University of Khartoum at a salary equivalent to just $1200.

Taha's genius blossomed at a very early age. Had it not been for the persistence and strong will of his mother, the world could have been deprived of the scholarly knowledge of one of the most notable physicists in modern times.

His life-long friend Dr. Kamal Al-Hadi of the International University of Africa related to Sudanow the really interesting story of Taha's mother. He said the story happened at a time when schools are scarce and scattered along far distances in Sudan. Hundreds competing candidates from remote villages and rural areas at the school age of 7 were striving neck-a-neck to get a seat from the already limited number of admission seats. Admission seats were limited to 40 only at the district where our scientist Taha resided. Admission committee was composed of education ministry officials, tribal chiefs and community leaders. Taha applied to join elementary school when he was seven but his application was declined. Then he applied again next year at the age of eight, only to be rejected admission once again. He was insistent and applied for the third time at the age of nine, but still he was denied admission to school! That was supposed to be his last chance as the admission committee did not consider elementary school admission applications from children over nine years of age.

With all the carefree attitude of a young chap, Mahjoub Taha opted to dash for game-play on the river bank with his peers rather than return home to disclose the rejection news to his mom.

When she sensed he was late, his mom went out looking for him. But upon hearing of her son's non-admission news, Mahjoub's mom was furious and she went straight into the admission committee venue to address the committee members angrily: "Why have you denied him admission for the third time? Is it because he is orphaned? Don't you have conscience? Aren't you God-fearing?" The committee members had to change their decision and finally Mahjoub got a chance to join elementary school.

At the final end-year exams Mahjoub scored the best marks and ranked first amongst all his peers. Ever since he remained on top of class until he finished his undergraduate schooling.

By the end of 1956, the American Herald Tribune organized the international Herald Tribune forum with the aim of introducing international student achievers to their American peers. Mahjoub was at secondary school level when he was nominated to represent Sudan in that forum based on the results of a national secondary school competition.

When he was back from the Herald Tribune Forum Mahjoub toured secondary schools and scientific institutes delivering lectures about learned lessons from his participation experience in the forum.

He had reportedly skipped some grades during his elementary, intermediate and secondary school education.

Upon his admission to the University of Khartoum, Mahjoub continued his path of scientific excellence achieving the best-student award for the final scientific preparatory exams for intermediate level at his first and second academic years successively.

In 1961, he was delegated by the University of Khartoum to the United Kingdom to complement his college studies in physics at Durham University. Accompanying him in that assignment was his peer Mohammed Abdulkarim Ahmed. The decision to delegate both of them to complement their studies in Durham University was motivated by the Faculty-of-Science's interest to qualify a core Sudanese teaching staff from amongst the ranks of its most distinguished students.

Professor Mahjoub was greatly attracted to the interacting issues of science and faith particularly with regard to the cosmic formation theories. He had delivered many lectures and written several articles on this topic at a time when atheism was a common dogma among scientists and physicists.

For example in 1966, the American "Time" magazine published a scientific article astonishingly entitled "Has God Died?" The title reflects a common supposition among scientific circles that with the great advancement of science there was no longer a need to inject theological existence into the interpretation theories of cosmic formation.

Mahjoub devoted a number of articles to refute atheist scientist's claims against the existence of god.

With all those distinguished scientific and academic achievements, professor Mahjoub was recognized for his genuine humility and modesty. He always avoided the lime lights and preferred to work and achieve in silence.

Mahjoub's colleague at King Saud University, Dr. Khidir Mohammed Al-Shaibani, wrote the following tribute in Mahjoub's commemoration:

"Mahjoub has left behind a rich legacy of scholarly and scientific contributions. But most important of all is that he has left behind memorable attributes of radiating love, high ethics and infectious genuine attitude of modesty. Deep inside me I have always known that Mahjoub's best enemies were his excessive modesty and severe asceticism. He used to avoid all sorts of lime lights though he was always keen on passing through the gist of his thoughts and academic knowledge to his students all through his academic career within the strict standards and guidelines he had set for his life, where he preferred his work to be free from hypocrisy and any search for notoriety".
