We join the ‘Open Arms’ crew as they embark on the most dangerous migrant route in the world — and one of their deadliest missions to date.

An estimated 19,000 people have been reported dead or missing in the Mediterranean Sea since 2014 as they attempt the treacherous boat journey from Libya to Europe, fleeing war, persecution and poverty.

Since its foundation in 2015, Spanish NGO Open Arms has rescued over 60,000 refugees. But nothing prepared it for the events that unfolded on November 11, 2020.

In a recent interview, UN Chief Economist Elliott Harris spoke about a ground-breaking change to national accounting that, for the first time, includes valuing nature in addition to more conventional economic measures. The System of Environmental-Economic Accounting – Ecosystem Accounting offers major scope for informing and improving decisions on economies, climate action and the protection of biodiversity.

Physicist Brian Greene takes you on a visual, conceptual, and mathematical exploration of Einstein’s spectacular insights into space, time, and energy. In just 11.5 hours, using nothing more advanced than high school algebra, journey from Einstein’s earliest musings on the speed of light to his startling realization that time can tick at different rates to his revolutionary discovery of the world’s most famous formula, E = mc2.

This is a more in-depth and mathematical version of the WSU Master Class “Space, Time, and Einstein.” https://youtu.be/CKJuC5CUMgU

Probability is the examination of uncertain processes, but it's useful for far more than games of chance: http://www.gresham.ac.uk/lectu....res-and-events/proba

The modern theory of probability is considered to have begun in 1654 with an exchange of letters between Blaise Pascal and Pierre de Fermat, and has developed since then into the discipline which examines uncertain processes. For example, although on tossing a coin you have no idea whether you will obtain heads or tails we know that if you keep doing it then in the long run it is very likely that the proportion of heads will be close to a half. The lecture will discuss this and other examples of random processes e.g. random walks and Brownian motion.

The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectu....res-and-events/proba

Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.

Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we may soon have the first picture of the event horizon of Sagittarius A*, the black hole at the center of the Milky Way galaxy. And, with the power of math, scientists are going even further, using equations to “look” inside black holes, peering at the central singularity where general relativity and quantum mechanics collide. Join Brian Greene and other leading physicists and astronomers on a journey to make darkness visible.

Jim explores what are the most popular interpretations of quantum mechanics and how we might need to be a little more specific when we talk about ‘reality’.
Jim's book "Quantum Reality" is now available on Amazon: https://geni.us/OF5X

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.

He gave up a tenured lectureship at the University of Reading after five years in order to gain experience in the commercial world. He worked for Shell International Petroleum for 11 years before leaving to establish his own business consultancy and training practice. He won the Royal Society of Chemistry’s Marlow Medal for his contributions to scientific research in 1989.

This talk was streamed live by the Ri on 14 July 2020.
