Ellenberg’s commitment to explanation, his exploration of the humanity of mathematics, and the tour de force of the final chapter in defense of a democracy girded by fairness and science are enough to remind you why he is America’s favorite math professor.”— Daily Beast

One 6 inches by 10 inches rectangle cake - It was a single layer cake baked using my chocolate cake recipe. The book cake would not look nice if it’s too tall, so I made a single layer cake. The height was approximately 2 inches. we teach geometry not to prove the exterior angles of a polygon add to 360 but rather to learn deductive reasoning with which to discern non-proofs. Like young Lincoln breaking things into their first principles until they become simple enough for him to understand I was unable to stop collecting quotes from various sections of this book. I will share them because many people will not read a book on geometry but may read a review and I think these thoughts are worth sharing with more people. Stay with me here:Unreasonably entertaining . . . reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning.” — The New York Times From the New York Times-bestselling author of How Not to Be Wrong—himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything. The Read Manchester campaign is run in partnership by Manchester City Council and the National Literacy Trust, and promotes reading for enjoyment through a programme of activities and events. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word 'geometry', from the Greek for 'measuring the world'. If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. 'Shape' shows us how." Finally, it helps preschoolers and kindergartners learn by singing songs and rhymes like these from Childhood 101.

The ultimate reason for teaching kids to write a proof is not that the world is full of proofs. It’s that the world is full of non-proofs, and grown-ups need to know the difference. It’s hard to settle for a non-proof once you’ve really familiarized yourself with the genuine article. I was sometimes jealous of how well Ellenberg described some ideas. (Yes, that's a problem I am ascribing to the book that really applies to me.)Walter weave his web into shapes in an attempt to make a sturdy, wind-proof web. Can you predict which shapes will withstand the wind’s strength?
