Episode notes

Gravitational field is a different kind of force, whatever you mean by that word force, right? Yes. We can think of gravity through, you know, as exchange of gravitons, the quantum particles of the gravitational field. A lot of physicists in modern day don't talk about fields. Where space time is flat, the gravitational field is very weak. But where space time is curved, because it's been curved by matter or energy, we say the gravitational field has strong influence there. Get it? O, ok, so it's the shape of space time, ok, i get you. Noa, not everything motold physics is easy to convey in a few words

In this conversation with quantum physicist, New York Times bestselling author, and BBC host Jim Al-Khalili reveals how 8 lessons from the heart of science can help us all get the most out of our lives.

Today’s world is unpredictable and full of contradictions, and navigating its complexities while trying to make the best decisions is far from easy. In this brief guide to leading a more rational life, acclaimed physicist Jim Al-Khalili invites readers to engage with the world as scientists have been trained to do. The scientific method has served humankind well in its quest to see things as they really are, and underpinning the scientific method are core principles that can help us all navigate modern life more confidently. Discussing the nature of truth and uncertainty, the role of doubt, the pros and cons of simplification, the value of guarding against bias, the importance of evidence-based thinking, and more, Al-Khalili shows how the powerful ideas at the heart of the scientific method are deeply relevant to the complicated times we live in and the difficult choices we make.
