Lucie Green takes us on a journey from the centre of the sun to planet earth in a run-down of the latest solar physics research.

Lucie's book "15 Million Degrees: A Journey to the Centre of the Sun" is available to buy now - https://geni.us/2oB8V
110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system.
Light takes eight minutes to reach Earth from the surface of the Sun. But its journey within the Sun takes hundreds of thousands of years. What is going on in there? What are light and heat? How does the Sun produce them and how on earth did scientists discover this? Since the Royal Institution was founded in 1799 our knowledge of the Sun has changed dramatically and much of the work was carried out at the Ri.
Join Lucie Green for an enlightening talk, taking you from inside the Sun to its surface and to Earth, to discover how the Sun works, how a solar storm can threaten the modern technology that society relies on and more of the latest research in solar physics.
Lucie Green is a Professor of Physics based at the Mullard Space Science Laboratory, UCL’s Department of Space and Climate Physics. She studies activity in the atmosphere of our nearest star, the Sun. In particular, she looks at immense magnetic fields in the Sun’s atmosphere which sporadically erupt into the Solar System.
Lucie is very active in public engagement with science, regularly giving public talks and appearing on TV shows like Sky at Night.

Loop quantum gravity aims to unify the theories of general relativity and quantum mechanics, as explained by Jim Baggott.

Quantum gravity is the holy grail for modern theoretical physicists – a single structure that brings together the two great theories of the 20th century: quantum mechanics and general relativity. One widely-known solution is string theory, which emerged from particle physics. In this talk, Jim Baggott will describe the other approach known as Loop Quantum Gravity. This theory starts from general relativity, borrows many ideas and techniques from quantum mechanics, and predicts that space itself is quantum in nature.

Jim Baggott is an award-winning science writer. He trained as a scientist, completing a doctorate in chemical physics at the University of Oxford in the early 80s, before embarking on post-doctoral research studies at Oxford and at Stanford University in California.
This talk was filmed at the Ri on 12 February 2019.

In this guest curated event on quantum biology, Jim Al-Khalili invited Philip Ball to introduce how the mysteries of quantum theory might manifest themselves at the biological level. Here he explains how the baffling yet powerful theory of the baffling yet powerful theory of the subatomic world might play an important role in biological processes.
Philip Ball is a science writer, writing regularly for Nature and having contributed to publications ranging from New Scientist to the New York Times. He is the author of many popular books on science, including works on the nature of water, pattern formation in the natural world, colour in art, and the cognition of music, and he has also broadcast on many occasions on radio and TV.
Jim Al-Khalili is Professor of Theoretical Physics and Professor of Public Engagement in Science at University of Surrey. He is author of several popular science books and appears regularly on radio and television. In 2007, he was awarded the Royal Society Michael Faraday Prize for Science Communication.
This event took place at the Royal Institution on 28 January 2015.

According to our best theories of physics, the fundamental building blocks of matter are not particles, but continuous fluid-like substances known as 'quantum fields'. David Tong explains what we know about these fields, and how they fit into our understanding of the Universe.

From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time.

Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.
Carlo Rovelli is a theoretical physicist who has made significant contributions to the physics of space and time. He has worked in Italy and the US, and is currently directing the quantum gravity research group of the Centre de physique théorique in Marseille, France. His books 'Seven Brief Lessons on Physics' and 'Reality Is Not What It Seems' are international bestsellers translated into forty-one languages.
This talk and Q&A was filmed in the Ri on 30 April 2018.

Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ). A mathematical simulation of this process is included along with a brief discussion of r and K selected species.
