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.

Where do we get our mathematical symbols from? Why is the set of integers called ℤ ? When was the equals sign first used? How about zero? Good notation tends to catch on quickly, whereas bad notation can obscure beautiful theory.

The lecture explores how the introduction of new notation has paved the way for new leaps in understanding, and considers some mathematical quirks of language, such as what the number 4 in English has in common with the number 11 in Russian.

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.
