Overview of Shape

In "Shape," mathematician Jordan Ellenberg reveals how geometry secretly governs everything from gerrymandering to biology. Called "unreasonably entertaining" by critics and praised by NYT as America's "favorite math professor," this book transforms abstract mathematics into an essential lens for understanding democracy, finance, and life itself.

The Strange Power Hidden in Shapes

Here's a puzzle that went viral across the internet, from philosophy journals to bodybuilding forums: How many holes does a straw have? Zero? One? Two? The debate reveals something profound-we lack a shared language for describing the most basic features of reality. Yet geometry offers exactly that language, one so fundamental that even under the influence of psychedelics, when higher reasoning dissolves, pure geometric forms emerge first in human consciousness. From pandemic modeling to artificial intelligence, from democratic redistricting to quantum physics, geometry permeates every aspect of modern life. It's not a dusty relic from high school but a living language evolving faster than ever before, shaping how we understand everything from disease spread to whether our votes actually count. The straw debate has merit because each position reveals flaws in our intuition. The "zero holes" argument fails because bagels clearly have holes. The "two holes" position can't define where one hole ends and another begins. The "one hole" theory seems reasonable until you apply it to human anatomy. Topology offers a way forward by focusing on essential properties while ignoring irrelevant details.
