History of Mathematics 17th century developments

Peter Gibson

November 5, 2019 Overview and historical context

The 17th century was marked by imperial expansion and rivalry. The Russian empire expanded to encompass vast territories, governed by the Romanov imperial family (which ruled from 1584-1917). In particular, Peter the Great (r. 1682-1725) consolidated both territory and political power. In western Europe there was rivalry between the French Bourbon kings and the Hapsburg rulers of Spain and Austria.

The Dutch Republic broke away from Spanish control at the end of the Thirty Years War (1618-1648). There was an expansion of naval power among European states, accompanying increased overseas trade and colonisation of the Americas.

The slave trade flourshed during this time.

Politically, the prevailing model was one of absolutist, dynastic monarchy, as typified by Louis XIV (r. 1643-1715) in or Peter the Great in Russia. (The situation in England was an exception, with the civil war having resulted in power sharing between the monarchy and the nobility.)

The balance of power shifted away from Spain and Portugal, toward Britain and France.

Overall, mercantalism was the dominant economic model, involving extraction of wealth from colonial territory in the Americas and elsewhere, and transportation of goods to Europe.

Just as political power gradually shifted toward Britain and France, so too did intellectual achievement.

Some mathematicians active in this period, in addition to Kepler, Galileo and Descartes: Girard Desargues (1591-1661) (1623-1662) (1601-1665) (1608-1647) Christiaan Huygens (1629-1695) John Wallis (1616-1703) (1630-1677)

P. Gibson Math 4400 4 / 19 Fermat was a lawyer and member of the parlement of Toulouse. He communicated with Blaise Pascal, , Ren´eDescartes, John Wallis, Gilles de Roberval, as part of a long distance community of scholars that would come to be known as the Republic of Letters.

What is clear, is that mathematics and physics were profoundly impacted by one person (who is traditionally credited with co-development of differential and integral calculus).

There were new developments in (synthetic) geometry, in probability, and in the calculation of areas of regions and lengths of curves.

A considerable amount of work centred on infinitesimals, about which there was much dispute.

Laplace credits Fermat with the discovery of differential calculus,

P. Gibson Math 4400 15 / 19 Newton entered Trinity College at Cambridge University in 1661.

P. Gibson Math 4400 16 / 19 In 1669 he bacame Lucasian Professor of Mathematics, taking the place of Isaac Barrow.

In the late 1680s he became famous, with the publication of his Principia.

In 1695 he left Cambridge to become Warden of His Majesty’s Mint.

During the years 1664-1666 Newton (having recently received his first degree) was forced to the family farm in Woolsthorpe because of the bubonic plague, which is estimated to have killed 100 000 people.
