What's the history and science behind the pursuit of the ghostly subatomic particle, the neutrino? Watch the Q&A (exclusively for channel members) here: https://youtu.be/IBnN26eKnLY Buy James's book here: https://geni.us/h32Bb This lecture was recorded on 17 August 2023. With approximately 100 trillion neutrinos passing through us every second, these particles hold the key to unlocking some of the Universe's greatest mysteries. From the discovery of neutrinos and their role in illuminating the Universe through neutrino telescopes to the challenges of detecting this elusive particle, this lecture explores the science behind the ghost particle. Additionally, we will explore the potential of neutrinos to answer some of the biggest questions in the universe, including the composition of dark matter and the Universe's origin. This is a unique opportunity to gain a deeper understanding of the science behind the neutrino and its impact on our understanding of the cosmos. 00:00 A revolution in astronomy 4:58 What exactly is a neutrino? 6:13 Where do neutrinos come from? 8:55 Nils Bohr and the Beta decay conundrum 12:14 Hans Bethe and the invisible particle solution 15:24 How NOT to find a neutrino 21:27 On the hunt for solar neutrinos 25:48 Three flavours of neutrinos 28:16 Neutrino oscillation and how it works 31:18 Probing the inside of the earth 34:47 Using neutrinos for astronomy 38:47 Matter over Antimatter 46:09 Could aliens communicate using neutrinos? 52:50 Looking at the birth of the universe --- James Riordon is a science journalist who has written for Science News, Scientific American, New Scientist, Popular Science, Washington Post, Science, Ad Astra, Physics Today, and Analytical Chemistry.

,2025 is the International Year of Quantum Science and Technology, as marked by the UN, to celebrate 100 years since the birth of quantum mechanics. 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. Ri Science Podcast episodes are released on the last Wednesday of every month. Subscribe wherever you get your podcasts to be notified as soon as episodes are released! --- Jess Wade is a British physicist in the Blackett Laboratory at Imperial College London, specialising in Raman spectroscopy. Her research investigates polymer-based organic light emitting diodes (OLEDs). Her public engagement work in science, technology, engineering, and mathematics (STEM) advocates for women in physics as well as tackling systemic biases such as gender and racial bias on Wikipedia.

,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.

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.
