There is no arrow of timet. We know that the causes always precede effects, but at fundamental physics level, which i don't understand,. I'm not quite sure i get that. But we know there's an hour of time pointing from past to future. And you can trace it all the way back to saying our universe was in a very highly ordered low entropy state at the big bang. So where does that past and future come from? Now, thethe consensus is that it's because ar the moves from a highly ordered to a disordered state, an increase in entropy, the amount of disorder.

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.
