Yesterday was Pi Day, when nerds around the world celebrate the ratio of a circle’s circumference to its diameter. (Pi, of course, begins with 3.14, hence 3/14 is Pi Day.) On Wednesday, students at COSAT created posters to honor that most famous of non-repeating, irrational numbers.

Until recently, mathematicians believed you couldn’t represent hyperbolic geometry in real space, but a Latvian math professor discovered a way ? using crochet. Some science educators realized those same hyperbolic shapes mimicked the forms in coral reefs. And now their Crochet Coral Reef Project has landed at the Smithsonian’s Museum of Natural History.

Listener Ben Coleman used to teach math, so he is no stranger to geometry. But it wasn’t until he discovered a book of origami and began creating shapes of his own that his passion for geometric forms was truly realized. Produced by Nick Heling.

The Geo Quiz answer today is Nancy, France; birthplace of mathematician Henri Poincare. He posed a problem known as the Poincare Conjecture. Now a Russian mathematician has solved it. Anchor Marco Werman finds out more from reporter Galina Stolyarova.

Anchor Lisa Mullins reveals the answer to our Geo Quiz today. We wanted the name of the continent that extends into all 4 hemispheres of Earth — north, south, east and west. The answer is Africa, which has portions both north and south of the equator, and portions both east and west of the prime meridian.
