Do We Need a New Theory of Gravity?

Birds are not merely descendants of dinosaurs — they are dinosaurs. For Yale evolutionary biologist and ornithologist Richard Prum, birds have been a lifelong passion and a window into some of evolution’s most intriguing mysteries.

In a wide-ranging conversation with co ...

Every time data travels — from smartphones to the cloud, or across the vacuum of space — it relies on a silent but vigilant guardian in the form of error-correcting codes. These codes, baked into nearly every digital system, are designed to detect and repair any errors that no ...

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everyt ...  Show more

Some see the world of thought divided into two types of ideas: evolutionary and revolutionary ideas. However, the truth can be more nuanced than that; evolutionary ideas can spur revolutions, and revolutionary ideas may be necessary to create incremental advancements. General rel ...  Show more

This episode is a weighty one. Some might say massive. It’s all about gravity. What is it? Why does it matter? Izzie and Dr Becky explore Einstein and Newton’s different ideas on the subject, plus Izzie visits the Royal Society to see Isaac Newton's original manuscript for his wo ...  Show more

Claudia de Rham has rather an unusual relationship with gravity.While she has spent her career exploring its fundamental nature, much of her free time has involved trying to defy it - from scuba diving in the Indian Ocean to piloting small aircraft over the Canadian waterfalls. H ...  Show more
