This lecture was recorded at the Ri on Monday 14 August 2023.
00:00 Einstein’s most important equation
3:37 Why Newton’s equations are so important
9:30 The two kinds of relativity
12:53 Why is it the geometry of spacetime that matters?
16:37 The principle of equivalence
18:39 Types of non-Euclidean geometry
26:26 The Metric Tensor and equations
32:22 Interstellar and time and space twisting
33:32 The Riemann tensor
37:45 A physical theory of gravity
43:28 How to solve Einstein’s equation
47:50 Using the equation to make predictions
51:05 How its been used to find black holes
The real Einstein's Equation is part of general relativity, which relates the curvature of spacetime to the mass and energy distributed within it.
Sean explains why the geometry of spacetime has anything to do with gravity, and how this famous equation expresses the way that spacetime curves.
Sean Carroll is Homewood Professor of natural philosophy at Johns Hopkins University. He won the Royal Society Winton Prize for his book about the search for the elusive Higgs boson, The Particle at the End of the Universe, and The Big Picture was an international bestseller. His most recent book is Something Deeply Hidden. He lives in Baltimore.
Copies of Sean's latest book, 'The Biggest Ideas in the Universe 1: Space, Time and Motion', are available from Amazon and all good bookstores.

But quantum science is one of the least diverse areas of science in terms of gender and other protected characteristics.
Jess Wade, a physicist and lecturer in functional materials at Imperial College London, has been fighting the inequality in quantum physics and beyond by creating thousands of Wikipedia pages for women scientists. Jess joins us this month to discuss the past, present, and future of quantum science along with what can be done to increase diversity within the field.

Life grows up in the universe by gradual degrees of evolution. Billions of years ago, there existed a vast population of bacteria. But it was only an elite group of these bacteria that evolved to become humans. In truth, we are lucky to be alive.
In the first of his CHRISTMAS LECTURES, Richard Dawkins explores the origins of life. Beginning with a look at our ancestry, he shows how the probability of our existence is very small. Becoming an ancestor is much more difficult than simple reproduction, and Richard reveals how our ancestors did what it took to survive and pass on their genes.
But although some of our life must be devoted to perpetuating it, surely there must be more to it? Richard explores the role of art and culture in society, and examines how the capabilities of the human body have enabled us to accomplish complex tasks.
When it comes to our understanding of the meaning of life, science is important. As Richard explains, science can help us uncover both when we arrived on this planet, and why we are here. Some people turn to the supernatural for the answer to such questions. Richard looks at the limitations of beliefs in the supernatural and uses a cannonball to prove why instead we should have faith in science and its predictions.

About the 1991 CHRISTMAS LECTURES
The world-famous evolutionary biologist Richard Dawkins presents the CHRISTMAS LECTURES on "our own growing knowledge of how life grows up in the universe."
Just as children grow up to be adults, so too does life gradually evolve on a planet over thousands of generations, to move from “nonliving simplicity” to become “living complexity”.
Combining beautiful writing with a range of illuminating demonstrations, the series featured a variety of wildlife, a virtual reality Lecture Theatre, and special guests – including the late Douglas Adams reading an excerpt from The Hitchhiker's Guide to the Galaxy.
