Born: 28 September 1881 in Maud, Aberdeenshire, Scotland

Died: 11 January 1947 in Edinburgh, Scotland


Edward Ross's father was William Ross (born in Helmsdall, Sutherland about 1832) who was a supervisor with the Inland Revenue. His mother was Ann Ross (born in Dundee about 1841) who was a school teacher. Edward had two older sisters, Marjory (born about 1870) and Hannah (born about 1875).

Edward Ross was six years old when his father died and at this time his mother moved from Maud, Aberdeenshire, to Edinburgh where he continued his schooling. Educated at George Watson's School in Edinburgh, Ross was dux of the school in 1898, matriculating at the University of Edinburgh in October of that year. His undergraduate career was outstanding: he won the Mitchell and Shortt Bursary, the Bruce of Grangehill and Falkland Bursary, and the Vans Dunlop Scholarship in Natural Philosophy. In 1902 he graduated M.A., with First Class Honours in Mathematics and Natural Philosophy.

After graduating Ross went to Cambridge, beginning his studies in October 1904. He was Seventh Wrangler in the Mathematical Tripos of 1904 and in the same year was awarded a Ferguson Scholarship. This is reported in The Scotsman of 5 October 1904:-

The Ferguson Scholarships

The examinations for these scholarships were conducted in the Trustees' Chambers, Glasgow, on 20, 21, 22 September 1904 by Andrew Munro, M.A., Queen's College, Cambridge in mathematics. The mathematics scholarship was divided between Edward Burns Ross, M.A., Edinburgh University, and Peter Fraser, M.A., Aberdeen University.

After a First Class performance in Part II of the Mathematical Tripos in 1906, Ross was appointed as Assistant to Karl Pearson at University College, London in October 1906. In the following year he accepted the post of Professor of Mathematics at the Christian College, Madras, India. He continued working there until 1932 when he was forced to retire due to ill health. He then returned to Edinburgh, living at 41 Liberton Brae, where he was looked after by his sisters for the final 15 years of his life during which time his health continued to deteriorate.

Ross joined the Edinburgh Mathematical Society in 1903 and remained a member throughout his career in India, and his retirement to Edinburgh. While still in Edinburgh he read his paper The contact of a member of a family of curves with the envelope to the Society at its meeting on Friday 13 January 1905. He was elected to the Royal Society of Edinburgh on 7 March 1921, his proposers being Sir Edmund T Whittaker, Cargill Gilston Knott, Ellice Martin Horsburgh, David Gibb.

An obituary, written by Edmund Whittaker, appears in the Royal Society of Edinburgh Year Book 1948/1949, page 43.

His death was reported in The Scotsman:-

Death of Former Madras Professor

The death has occurred at his home, 41 Liberton Brae, Edinburgh of Professor Edward Burns Ross, who in 1933 retired from the post of Professor of Mathematics in Madras Christian College. Educated at Edinburgh University, where he graduated M.A., and subsequently at Cambridge, he was appointed to Madras College in 1906. A zealous teacher, he exerted a powerful religious influence in the College, was a generous friend of the students, and gave much time and thought to the extension of the College library. In 1915 he was elected a Fellow of the Royal Society of Edinburgh. Professor Ross was 65 years of age.

الجبر أحد الفروع الرئيسية في الرياضيات، حيث إن التمكن من الرياضيات يعتمد على الفهم السليم للجبر. ويستخدم المهندسون والعلماء الجبر يومياً، وتعول المشاريع التجارية والصناعية على الجبر لحل الكثير من المعضلات التي تتعرض لها. ونظراً لأهمية الجبر في الحياة العصرية فإنه يدرّس في المدارس والجامعات في جميع أنحاء العالم. ويُعجب الكثير من الدارسين للجبر بقدرته وفائدته الكبيرتين، إذ باستخدام الجبر يمكن للمرء أن يحل كثيرًا من المسائل التي يتعذر حلها باستخدام الحساب فقط.وجاء اسمه من كتاب عالم الرياضيات والفلك والرحالة محمد بن موسى الخورازمي.


يعتبر علم المثلثات Trigonometry علماً عربياً ، فرياضيو العرب فضلوا علم المثلثات عن علم الفلك كأنهما علمين متداخلين ، ونظموه تنظيماً فيه لكثير من الدقة ، وقد كان اليونان يستعملون وتر CORDE ضعف القوسي قياس الزوايا ، فاستعاض رياضيو العرب عن الوتر بالجيب SINUS فأنت هذه الاستعاضة إلى تسهيل كثير من الاعمال الرياضية.

تعتبر المعادلات التفاضلية خير وسيلة لوصف معظم المـسائل الهندسـية والرياضـية والعلمية على حد سواء، إذ يتضح ذلك جليا في وصف عمليات انتقال الحرارة، جريان الموائـع، الحركة الموجية، الدوائر الإلكترونية فضلاً عن استخدامها في مسائل الهياكل الإنشائية والوصف الرياضي للتفاعلات الكيميائية.
ففي في الرياضيات, يطلق اسم المعادلات التفاضلية على المعادلات التي تحوي مشتقات و تفاضلات لبعض الدوال الرياضية و تظهر فيها بشكل متغيرات المعادلة . و يكون الهدف من حل هذه المعادلات هو إيجاد هذه الدوال الرياضية التي تحقق مشتقات هذه المعادلات.
