Mathematical formulas are as much a miracle as the brilliant works of great composers and writers, says the author of several best-selling books, mathematician and philosopher Chaim Shapira. For anyone who wants to broaden their horizons, he offers an introduction to the mathematical theories surrounding the most beautiful concept mankind has ever created—the concept of infinity. This concept worried many prominent thinkers, including Zeno and Pythagoras, Georg Cantor and Bertrand Russell, Sophia Kovalevskaya and Emmy Noether, al-Khwarizmi and Euclid, Sophie Germain and Srinivasa Ramanujan. Since the world of infinity is full of paradoxes, there are many of them in this book: Zeno’s aporia, Hilbert’s Hotel Infinity, the paradox of Achilles and the gods, the paradox of Heaven and Hell, the Ross-Littlewood paradox about tennis balls, Galileo’s paradox and many others. “I will tell the reader. -for the non-specialist, it’s simple and clear about the two mathematical theories that I find most fascinating—number theory and set theory, both of which have to do with infinity. Along with this, I will offer mathematical thinking strategies that allow the reader to test their ability to solve truly fascinating mathematical problems." (Chaim Shapira)
