"On November 25th, 1915, Albert Einstein published his field equations of general relativity and reinvented gravity. Rather than being some mysterious unseen force pulling objects together, gravity, Einstein told the world, is a manifestation of the curvature of space-time caused by the presence of massive objects. But Einstein's theory wasn't born in a vacuum, not even the vacuum of space. Instead, the theory of general relativity relies upon complicated geometry; Einstein worked closely with mathematicians Marcel Grossmann, David Hilbert, Tullio Levi-Civita, and others as he pieced together his theory of gravity. In The Gravity of Math, the writer Steve Nadis and mathematician Shing-Tung Yau tell the story of how our view of the universe has been shaped and informed by mathematics, particularly when it comes to the enigmatic workings of gravity. Mathematicians have played a pivotal role in investigating relativity and gravity, gaining insights on phenomena like black holes, gravitational waves, and the Big Bang - in some cases uncovering key results decades, or even a century, before any experimental or observational data became available. An insightful and comprehensive study, The Gravity of Math explores how our understanding of math has defined our understanding of the universe. Gravity's reach is ostensibly boundless, and so is that of mathematics, which can carry us to the edge of infinity and back"--

In the twentieth century, American mathematicians began to make critical advances in a field previously dominated by Europeans. Harvard's mathematics department was at the center of these developments. A History in Sum is an inviting account of the pioneers who trailblazed a distinctly American tradition of mathematics--in algebraic geometry, complex analysis, and other esoteric subdisciplines that are rarely written about outside of journal articles or advanced textbooks. The heady mathematical concepts that emerged, and the men and women who shaped them, are described here in lively, accessible prose. The story begins in 1825, when a precocious sixteen-year-old freshman, Benjamin Peirce, arrived at the College. He would become the first American to produce original mathematics--an ambition frowned upon in an era when professors largely limited themselves to teaching. Peirce's successors transformed the math department into a world-class research center, attracting to the faculty such luminaries as George David Birkhoff. Influential figures soon flocked to Harvard, some overcoming great challenges to pursue their elected calling. A History in Sum elucidates the contributions of these extraordinary minds and makes clear why the history of the Harvard mathematics department is an essential part of the history of mathematics in America and beyond.
