Infinite Powers: How Calculus Reveals the Secrets of the Universe by Steven Strogatz

Just finished Infinite Powers: How Calculus Reveals the Secrets of the Universe by Steven Strogatz in which he tackles the intricate details of calculus, revealing its profound impact on our understanding of the universe. The author invites readers on a captivating journey through the history and applications of this seemingly notorious mathematical tool specially for secondary school goers.

The book commences by examining the mysterious concept of infinity, tracing its evolution from ancient civilizations to its pivotal role in calculus. Strogatz navigates the complexities of infinity with clarity, exploring Zeno's paradoxes and the distinction between potential and completed infinity. He skillfully demonstrates how calculus harnesses the power of infinity to bridge the gap between the curved and the straight (literally), enabling us to solve seemingly impossible geometric problems.

"Without calculus, we wouldn't have cell phones, computers, or microwave ovens. We wouldn't have radio. Or television. Or ultrasound for expectant mothers, or GPS for lost travelers. We wouldn't have split the atom, unraveled the human genome, or put astronauts on the moon. We might not even have the Declaration of Independence."

The author then goes on to introduce Archimedes, a brilliant mathematician and inventor who revolutionized our understanding of curves. Through his ingenious method of exhaustion, Archimedes paved the way for integral calculus, demonstrating its ability to unravel the mysteries of circular shapes and beyond. Strogatz's vivid descriptions of Archimedes's work bring this ancient genius to life, showcasing his profound impact on the development of maths. The story then shifts to the dawn of differential calculus, where the mysteries of curves, motion, and change converge. The author explores the contributions of Fermat and Descartes, highlighting their groundbreaking work on analytic geometry and tangent lines. He discusses their rivalry and the intellectual environment of the 17th century, setting the stage for the momentous breakthroughs that followed. The book culminates in the monumental achievements of Newton and Leibniz, who independently developed the foundations of modern calculus. The book explains in detail their discoveries, including the fundamental theorem of calculus, which revolutionized our ability to solve problems related to motion, change, and the accumulation of quantities.

"To shed light on any continuous shape, object, motion, process, or phenomenon—no matter how wild and complicated it may appear—reimagine it as an infinite series of simpler parts, analyze those, and then add the results back together to make sense of the original whole."

The author goes beyond the traditional textbook approach, showcasing the myriad applications of calculus in our modern world. From predicting the spread of epidemics to designing safer airplanes, calculus has empowered us to understand and shape the world around us. Strogatz's engaging prose and relatable examples make these applications accessible and fascinating, even for those without a strong mathematical background. The book’s writing style is appealing, seamlessly blending historical anecdotes, clear explanations, and relatable examples to make calculus not only understandable but also truly enjoyable for readers of all backgrounds. It is a very good resource to explore calculus specially for people from non-STEM backgrounds and also for understanding the history and evolution of maths in general and calculus in particular.

While Strogatz's enthusiasm for the elegance and explanatory power of calculus is undeniable, his venture into philosophy at the end of the book oversimplifies the complex relationship between science and faith. He implies that the remarkable accuracy of certain scientific theories diminishes the role of faith in science, overlooking the inherent assumptions and beliefs that underpin the scientific process itself. Any student of philosophy of science would know there is a lot written on this which cannot be narrated here.

In conclusion, "Infinite Powers" stands as a testament to the enduring power and beauty of calculus, and I wholeheartedly recommend it to anyone seeking to understand the language of the universe and appreciate the profound impact of calculus on our world.
