![]() Mathematical moments Louis Antoine de Bougainville Born: 11 Nov 1729 in Paris, France Died: 31 Aug 1811 in Paris, France Louis-Antoine de Bougainville was an acclaimed mathematician who wrote a well-known calculus book. However, he is more widely remembered for his exploits as an explorer and soldier. Such were his exploits as an explorer, his name is given to the largest of the Solomon Islands in Papua New Guinea, to the strait which divides it from the island of Choiseul, and to the strait between Mallicollo and Espiritu Santo islands of the New Hebrides group. In the Falklands, Port Louis and Isla Bougainville commemorate his name. The South American climbing shrub Bougainvillea is also named after him. Whilst these days Bougainville's legacy is courtesy of his life as an explorer, he showed early promise as a mathematician. After completing his secondary schooling, in 1752 he wrote Traite du calcul - integral extending de l'Hopital's book, written more that half a century earlier, to cover integral calculus and updating the differential calculus. It was written of him that: "He brought such clarity and order to the subject, as well as incorporating new work, that he achieved immediate recognition." This work led to Bougainville's election to the Royal Society of London in 1756, when he also published a second volume. This could have been the start of a promising mathematics career for Bougainville. However, his life took a different tact when he quit mathematics and joined the army, whereupon he distinguished himself in the French and Indian War. As a member of the navy, in 1764 he sailed from France to the Falkland Islands, where he established a French colony. In 1766, he was commissioned by the French government to sail round the world as the French joined other European countries in colonising lands in the Southern Hemisphere. By the end of March 1768, Bougainville had discovered the islands in the archipelago of , now French Polynesia. He also found Tahiti, but was 8 months behind Englishman Samuel Wallis. He reached modern day Bougainville reef, just to the east of Australia's Great Barrier Reef, but somehow missed sighting Australia. He found the Louisiade Archipelago, an island group of Papua New Guinea, 200 km southeast of the island of New Guinea, which he named after Louis XV of France. Continuing his journey north, he discovered two of the Treasury Islands, sailed past Choiseul island, and the now-named Bougainville Island. He made it home in March 1769 as the first Frenchman to sail round the World. His systematic astronomical observations provided important navigation charts to later explorers. From 1779 to 1782 he served as commodore in operations of the French fleet off North America, supporting the American Revolution, but was later court- martialled after defeat off Martinique. During the French Revolution, he escaped the massacres of Paris in 1792 and settled in Normandy. Napoleon made him a senator, a count, and a member of the Legion of Honour. Not bad for a mathematician with a penchant for calculus! More information at:http://www-history.mcs.st-andrews.ac.uk/ Biographies/Bougainville.html Mally

![]() Whereas most of us might have heard of Alfred North Whitehead, the mathematician philosopher, his nephew Henry Whitehead may seem an obscure name. Surprisingly he was born in Madras (now known as Chennai) in the South of India from the same place where Ramanujan hailed from. Well he did not spend much time there and was sent to England when 18 months old. Read his fascinating life story in the following article. Of special note is his openess in dealing with very ordinary people when he made them feel his equal, a trait seldom seen these days! Henry Whitehead's father was The Right Rev Henry Whitehead, Bishop of Madras in India. His mother, Isobel Duncan, was the daughter of the Rector of Calne, Wiltshire, so Henry came from a family deeply involved with the Church. However, Henry Whitehead's family also had strong academic connections; in particular there was a strong tradition of mathematical excellence. His mother had studied mathematics at Oxford University, being one of the early women undergraduates, while the famous mathematician and philosopher, Alfred North Whitehead, was his uncle. Although Henry was born in India he lived in England from the age of about eighteen months. It was at that age that his parents brought him back from India and left him in the care of his maternal grandmother who lived in Oxford. His parents then returned to India and Henry saw little of them while he was growing up. It would not be until his father retired when Henry was sixteen years old that they returned to England. Henry's childhood in Oxford was a quiet one since [6]:- ... it was a very peaceful place and he would recall going for drives with his grandmother in her carriage and seeing the horsedrawn buses in town. Henry did quite well at primary school, both academically, socially and in sport. He was [6]:- ... of above average intelligence, good at games, prone to be careless in his work, but with a great capacity for enjoying life. If he had worked harder he might have won a scholarship to Eton... Despite the lack of a scholarship to Eton, Whitehead was successful in the Entrance Examination and began a happy period at Eton where he specialised in mathematics, yet never showed himself as a mathematical genius. One reason why this outstanding mathematician only appeared "good" at school was a whole range of other interests which occupied him [6]:- His exuberance, gaiety and intelligence made him many friends and his irrepressible high spirits and disregard for authority sometimes strained the patience of his tolerant and long suffering housemaster. His personal popularity got him elected to Pop, and his athletic prowess won him a place in the cricket second eleven, his fives colours and a silver cup at boxing. Another reason why he failed to shine academically may have been due to an inner sadness at being separated from his parents. Whatever the reasons it made his desired progress harder than it might otherwise have been. Whitehead wanted to go to Balliol College, Oxford, to study mathematics but his mathematics teacher at Eton did not think that he stood a chance of winning a scholarship. He wrote [6]:- In pure geometry he has not been over diligent ... he would have been more successful in mathematics if he had been less so at cricket. The mathematics teacher was wrong, however, and in March 1923 Whitehead did win a scholarship to study at Balliol College. At Balliol Whitehead was tutored by J W Nicholson, who had been a student of Whitehead's uncle A N Whitehead. However, Nicholson's health was poor and Whitehead was tutored frequently by H Newboult at Merton College. As Eton had done, however, Oxford also provided a whole range of distractions to Whitehead. He played many sports including cricket, squash, tennis, and boxing. His interest in cricket brought him into contact with G H Hardy, so the sporting interests had some academic benefits. At Oxford Whitehead developed another passion, namely playing poker. He claimed that his mother taught him how to play the game when he was a young child recovering from an illness. Whitehead played poker for quite large sums of money while at Oxford although his friends did not always pay what they owed him. At Oxford Whitehead showed himself to be better than the "good" at mathematics which he had displayed at Eton. Despite his success, and the award of a First Class degree, he did not consider himself sufficiently talented for an academic career so, in 1927, he joined the firm of stockbrokers Buckmaster and Moore. By this time his parents had returned from India and were living in the village of Sulham in Berkshire and Whitehead lived there and travelled to his job in the city of London every day. It took not much over a year of work at the stockbrokers to convince Whitehead that the City was not the life for him so, in 1928, he returned to the University of Oxford. While at Oxford Whitehead met Veblen, who was on leave from Princeton. He attended a seminar which Veblen gave on differential geometry and it must have been a very fine talk for it persuaded Whitehead that he would undertake research in that topic. Veblen supported Whitehead's application for a Commonwealth Fellowship to enabled him to study for a Ph.D. at Princeton. Whitehead arrived at Princeton in the summer of 1929 to begin his research. He worked mainly on differential geometry although towards the end of his three years there he became interested in topology. He was awarded his doctorate from Princeton in 1932 for a dissertation entitled The Representation of Projective Spaces. Whitehead's joint work with his doctoral supervisor Veblen led to The Foundations of Differential Geometry (1932), now considered a classic. It contains the first proper definition of a differentiable manifold. As we mentioned Whitehead's interests turned more towards topology near the end of his three years in Princeton when he collaborated with Lefschetz in proving that all analytic manifolds can be triangulated. In this area he is best remembered for his work on homotopy equivalence. The three years at Princeton were happy ones for Whitehead and he [6]:- ... had throughout his life a really deep affection for [Princeton] and its inhabitants, ranging from the Dean of the Graduate College to the barman at "Andy's". Whitehead returned to Oxford after being awarded his doctorate and he was elected to a Fellowship at Balliol College in 1933. In the following year Whitehead married Barbara Sheila Carew Smyth (one of the authors of [6]) who was a concert pianist [3]:- They shared great zest for life and enjoyed a marriage of surpassing happiness. They lived at first in St Giles, Oxford, but later moved to North Oxford after their first of their two sons was born. Their home there [6]:- ... became a meeting place for mathematicians, where there was generally a mug of beer or a cup of tea and always a warm welcome, and a pencil and a block of paper each for host and guest to write their thoughts on. Many ideas were exchanged and many informal seminars took place in his study. Soon after his return to England, Whitehead wrote another major work on differential geometry On the Covering of a Complete Space by the Geodesics Through a Point (1935). Whitehead also studied Stiefel manifolds and set up a school of topology at Oxford. However, events would soon cause a break in Whitehead's career. The Nazi moves against Jewish mathematicians gave Whitehead great distress, and he actively helped many to escape to safety. In particular he helped Eilenberg and Dehn, while Schrödinger came to live in his home after escaping from Austria. Whitehead left Oxford in 1940 to undertake war work in London, spending [6]:- ... the night of the worse blitz on London sitting in his friend's wine cellar placidly working at mathematics. He afterwards congratulated himself on his high standard of morality as not one bottle was [opened]. After working at the Board of Trade, at the Admiralty, and finally at the Foreign Office, during the War, Whitehead returned to his home in North Oxford when World War II ended. In 1947 he was appointed to the Waynflete Chair of Pure Mathematics at Oxford. At that time Whitehead moved from Balliol College to Magdalen College. Whitehead's father died in 1947 and his mother died six years later in 1953. She had owned a small farm and when Whitehead inherited the cattle he and his wife decided to buy Manor Farm in Noke, north of Oxford. The farm was run mainly by Whitehead's wife but he took a keen interest in the farm where the couple lived until Whitehead's death. His death, while on a visit to the Institute for Advanced Study at Princeton during a Sabbatical year he was spending in the United States, was totally unexpected [6]:- In May 1960, without any previous warning symptoms or illness, he died of a heart attack in Princeton, where his mathematical life had begun. Whitehead's personality is clearly described in [6]:- He was able to reach across the barriers of age, class and nationality to talk on equal terms with anyone who shared his passion for mathematics. The long series of collaborative papers written between 1950 and 1960 reflects his eagerness to share his ideas and to interest himself in the results of others, which remained undiminished to the end of his life. It was in long mathematical conversations, in which ever detail had to be hammered out till he had it quite correct and secure that he most delighted and it is by these conversations, gay and informal, in which he contrived to make everyone his own equal, that he will be best remembered by those who knew him. His career produced mathematical results which would have a major influence on the directions of mathematical research. However, as the authors of [6] relate, his influence extended beyond this:- His influence on the development of mathematics during his active lifetime can be partly measured by the innumerable references, implicit and explicit, in current mathematical literature on algebraic and geometric topology; but it could not have been so great without the generosity and enthusiasm which he poured into every mathematical enterprise and which inspired such deep affection in all who knew him well. Whitehead received several honours for outstanding mathematical achievements, but he died at the age of 55 when at the height of his powers, so did not live t receive awards which normally come later in life. He was elected to the Royal Society in 1944. He served the London Mathematical Society in a number of ways, most notably as president during 1953-55. Max Newman, who was a friend of Henry Whitehead from 1929 until the end of his life, writes [3]:- The immediate attractiveness of his tremendous high spirits and friendly manners would not have sufficed to bring him the lasting affection of mathematical friends all over the world if it had not been backed, from his earliest days, by a most delicate perception of the thoughts and feelings of the person he was talking to, and a deep enjoyment and tolerance of all kinds of human behaviour. He had the dislike of formality which is not uncommon among men of science and learning, but it was a comfortable, not an uncomfortable, informality which enabled him to soften the high and exalted as easily as he could unfreeze the young and timid. Those leisurely, searching conversations, enjoyed on exactly the same terms by all comers, on a walk over the farm, with his not very obedient gun-dog, or sitting in arm chairs with pencils and blocks of paper for following the details, were as refreshing and enlivening after 30 years as on the first day.

hello, when I was young, I heard an anecdote about the math battles between the teacher and the student.
The student is the great and famous Mathematician. I believe he is Fermat, but I cannot find the below anecdote about him. The math teacher (I call A) of Fermat learns a concept of a secret math formula that solves many problems from his own teacher (teacher of teacher of the great mathematician Fermat). The grand teacher wants the teacher A keeps the formula secretly, but teacher A pass the secret down to the Fermat because teacher A sees the talent in Fermat. The grand teacher learns the incident and want to have math fight against the teacher A. The result is teacher A loses and dies because he has to receive public punishments (a sort of). Then, Fermat takes revenge by developing the formula further and wins the fight against the grand teacher. Anyone knows about this anecdote? |
