Infinitesimal

How a Dangerous Mathematical Theory Shaped the Modern World

By: Amir Alexander

Narrated by: Ira Rosenberg

Pulsing with drama and excitement, Infinitesimal celebrates the spirit of discovery, innovation, and intellectual achievement - and it will forever change the way you look at a simple line.

On August 10, 1632, five men in flowing black robes convened in a somber Roman palazzo to pass judgment on a deceptively simple proposition: that a continuous line is composed of distinct and infinitely tiny parts. With the stroke of a pen the Jesuit fathers banned the doctrine of infinitesimals, announcing that it could never be taught or even mentioned. The concept was deemed dangerous and subversive, a threat to the belief that the world was an orderly place, governed by a strict and unchanging set of rules. If infinitesimals were ever accepted, the Jesuits feared, the entire world would be plunged into chaos.

In Infinitesimal, the award-winning historian Amir Alexander exposes the deep-seated reasons behind the rulings of the Jesuits and shows how the doctrine persisted, becoming the foundation of calculus and much of modern mathematics and technology. Indeed, not everyone agreed with the Jesuits. Philosophers, scientists, and mathematicians across Europe embraced infinitesimals as the key to scientific progress, freedom of thought, and a more tolerant society. As Alexander reveals, it wasn’t long before the two camps set off on a war that pitted Europe’s forces of hierarchy and order against those of pluralism and change.

The story takes us from the bloody battlefields of Europe’s religious wars and the English Civil War and into the lives of the greatest mathematicians and philosophers of the day, including Galileo and Isaac Newton, Cardinal Bellarmine and Thomas Hobbes, and Christopher Clavius and John Wallis. In Italy, the defeat of the infinitely small signaled an end to that land’s reign as the cultural heart of Europe, and in England, the triumph of infinitesimals helped launch the island nation on a course that would make it the world’s first modern state.

From the imperial cities of Germany to the green hills of Surrey, from the papal palace in Rome to the halls of the Royal Society of London, Alexander demonstrates how a disagreement over a mathematical concept became a contest over the heavens and the Earth. The legitimacy of popes and kings, as well as our beliefs in human liberty and progressive science, were at stake - the soul of the modern world hinged on the infinitesimal.

Great book on how infinitesimal struggled to exist.

Overall the audio was good. Infinitesimal is a great story that mixes math with history and informative in the great players of mathematics.

needs pictures

needs pictures to understand the diagrams that the author uses to describe the concepts. the second half is easier to understand.

Good Math History

Infinitesimal may tell you more than you want to know. I suspect that the reviews give the book less than a 5.0 rating is that the book gives the Jesuits a very hard time for holding back math in Italy for at least 100 years by burning one person at the stake and confining Galileo to house arrest for the end of the life for believing that math could progress by considering small units of measurement that had no width. They intimidated many other mathematicians to silence less they suffer the same fate.

Had they stuck to religious matters, calculus may have been discovered a century earlier and in Italy.

The book is filled with an immense amount of detail. It tells of the problems of using geometric solutions as analogous to political solutions to political problems.

A sprawling historic account of...

A sprawling historic account of an inflection point in the history of science and mathematics.

Amir Alexander tells the story of how the concept of the infinitesimal became a flash point for opposing personalities in the Catholic Church, then the English parliament. He does so in great detail, sometimes going on circumlocutious tangents to set the scene. The book is more for historians than for philosophers of science and mathematics. Still, if you have the patience, the stories he tells will leave you with a very different perspective on how powerful and contentious mathematical debates can be.

He contends that this conflict over infinitesimals helped to determine the cultural and technological fates of England and Italy. I am unsure about this hard to verify assertion. Still, there is no doubt for me that analysis is a deeply philosophical and not just logicomathematical concept.

An Amazing Listen to intrigue and history. Highly recommended.

A fantastic review of political - mathematical - religious history. Presented so the layperson can understand and follow. The two concepts need to be clearly outlined or perhaps I need to review the text again.

Definitely worth listening to. The book brings sense to some of histories extreme views. It also provides understanding for the great advances in the scientific, political and religious areas.

Highly recommended.
