Science, Tech, Engineering and Math
Your eyes and ears don’t tell you the truth. That’s not what they’re for. The senses evolved to enable us to survive and succeed in the world, not to represent it accurately. Now, for the first time, science is revealing exactly how the sense organs receive information, process it, and pass it to the brain, providing deep insight into why we experience the world the way we do—and what it might be like for future technology to transform such experiences, perhaps allowing us to see infrared light or feel magnetic north. Join an eminent group of neuroscientists and philosophers for an ear, tongue, nose and eye-opening adventure that challenges everything we experience in search of the true nature of reality.

For the last half century we have slipped the surly bonds of earth with landers, rovers and spacecraft that have allowed us to touch the very edge of the Solar System and beyond. Voyager 1, launched in 1977, has entered interstellar space. The Parker Solar Probe will soon graze the Sun. We have visited and photographed all eight planets and their moons, and powerful space telescopes are seeking signs of life on thousands of planets we have discovered circling other stars. Capping it off, we now have the first image of a black hole, at the heart of a galaxy 55 million light years away. Join us for a trip across the cosmos, guided by renowned astronomers and space scientists whose spacefaring probes provide humankind’s sharply focused eyes in the skies.

Stuff happens. The weather forecast says it’s sunny, but you just got drenched. You got a flu shot—but you’re sick in bed with the flu. Your best friend from Boston met your other best friend from San Francisco. Coincidentally. What are the odds? Risk, probability, chance, coincidence—they play a significant role in the way we make decisions about health, education, relationships, and money. But where does this data come from and what does it really mean? How does the brain find patterns and where can these patterns take us? When should we ditch the data and go with our gut? Join us in a captivating discussion that will demystify the chancy side of life.

Josh Tenenbaum and an experiment in ESP. 00:00
Risk, Probability, and Chance. 02:54
Marcus du Sautoy's Introduction. 06:32
Participant Introductions. 07:27
Are we good or bad at interpreting numbers? 09:45
The Monty Hall problem. 16:00
The fight or flight math means we understand numbers? 21:50
The "numbers are important" experiment. 25:33
VerizonMath: Verizon doesn't know Dollars from Cents. 29:30
If you play a lottery and there is 1 winner in a 1000, what is your percent of winning? 35:30
How well are our brains tuned for evidential data. 39:33
What is the birthday problem? 45:15
The way probability's are phrased are as important as the numbers. 53:31
Do we have a conception of a million? 01:03:28
What is a prior? 01:09:05
Josh Tenenbaum ESP experiment results. 01:15:19
"Numbers are important" experiment results. 01:20:45
How do we get a statistical society? 01:25:25
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.

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.

Mathematics has proven to be "unreasonably effective" in understanding nature. The fundamental laws of physics can be captured in beautiful formulae. In this lecture I want to argue for the reverse effect: Nature is an important source of inspiration for mathematics, even of the purest kind. In recent years ideas from quantum field theory, elementary particles physics and string theory have completely transformed mathematics, leading to solutions of deep problems, suggesting new invariants in geometry and topology, and, perhaps most importantly, putting modern mathematical ideas in a `natural’ context.

You exist. You shouldn’t. Stars and galaxies and planets exist. They shouldn’t. The nascent universe contained equal parts matter and antimatter that should have instantly obliterated each other, turning the Big Bang into the Big Fizzle. And yet, here we are: flesh, blood, stars, moons, sky. Why? Come join us as we dive deep down the rabbit hole of solving the mystery of the missing antimatter.

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.

Forget what you think you know about dark matter. After a 30-year search for a single, as yet unidentified, species of dark matter particle that would make up some 25% of the mass of the universe, physicists are starting to consider novel explanations. Some envision invisible matter hiding within the folds of extra spatial dimensions. Others suggest not one kind of dark matter particle, but numerous species inhabiting a shadow universe. Others still conjecture that dark matter doesn’t exist, and instead propose that the laws of gravity need modification. We’ll bring together leading thinkers on dark matter—the revolutionary and conventional alike—for a distinctly unconventional discussion on the dark universe.
