Credited with developing the modern mathematical treatment of the motion of airplanes in flight. In 1888, Bryan developed mathematical models for fluid pressures within a pipe and for external buckling pressures. These models are still used today. Aside from minor differences in notation, Bryan's 1911 equations are the same as those used today to evaluate modern aircraft. Born at Cambridge, he was Professor of Mathematics at Bangor University 1896 till 1928.[2]
Born in Anglesey in 1675, was the first recorded mathematician to use the symbol π in its present sense in 1706, though it would not achieve widespread adoption until used by famed Swiss mathematician Euler.
Wrote a paper on the proper method of calculating the values of contingent reversions which were said to have exercised a beneficial influence in drawing attention to the inadequate calculations on which many insurance and benefit societies had recently been formed. In 1769 Price received the degree of D.D. from the university of Glasgow for this work. He also wrote on finance, economics, probability, and life insurance. Price edited Bayes's major work An Essay towards solving a Problem in the Doctrine of Chances (1763), which contains the Bayes' Theorem with an introduction to the paper which provides some of the philosophical basis of Bayesian statistics. In 1765 he was elected a Fellow of the Royal Society in recognition of his work on the legacy of Bayes.
Sixteenth-century inventor of the equals sign was from Tenby. As it has been suggested, "[h]is equals sign was an invention that, while slow in becoming universally adopted, is still perhaps the most fundamental thing ever invented by a Welsh person."[24].
Influential Britishthinker of the twentieth century, though more properly a philosopher than a mathematician, was of English descent but born in Monmouthshire.
