Seth Llyod is a Professor in the Department of Mechanical Engineering at the Massachusetts Institute of Technology MIT. His talk, “Programming the Universe”, is about the computational power of atoms, electrons, and elementary particles.

A highly recommended watch.

A musical investigation into the nature of atoms and subatomic particles, the jiggly things that make up everything we see. Featuring Morgan Freeman, Stephen Hawking, Michio Kaku, Brian Cox, Richard Feynman, and Frank Close.

Ever since a monk called Mendel started breeding pea plants we’ve been learning about our genomes. In 1953, Watson, Crick and Franklin described the structure of the molecule that makes up our genomes: the DNA double helix. Then, in 2001, scientists wrote down the entire 3-billion letter code contained in the average human genome. Now they’re trying to interpret that code; to work out how it’s used to make different types of cells and different people.

The ENCODE project, as it’s called, is the latest chapter in the story of you.

Neuroscientist Daniel Wolpert starts from a surprising premise: the brain evolved, not to think or feel, but to control movement. In this entertaining, data-rich talk he gives us a glimpse into how the brain creates the grace and agility of human motion.

Why you should listen to him (From TED):

Consider your hand. You use it to lift things, to balance yourself, to give and take, to sense the world. It has a range of interacting degrees of freedom, and it interacts with many different objects under a variety of environmental conditions. And for most of us, it all just works. At his lab in the Engineering department at Cambridge, Daniel Wolpert and his team are studying why, looking to understand the computations underlying the brain’s sensorimotor control of the body.

As he says, “I believe that to understand movement is to understand the whole brain. And therefore it’s important to remember when you are studying memory, cognition, sensory processing, they’re there for a reason, and that reason is action.” Movement is the only way we have of interacting with the world, whether foraging for food or attracting a waiter’s attention. Indeed, all communication, including speech, sign language, gestures and writing, is mediated via the motor system. Taking this viewpoint, and using computational and robotic techniques as well as virtual reality systems, Wolpert and his team research the purpose of the human brain and the way it determines future actions.

National Geographic Documentary. Over the last three decades, science has been advancing our understanding of stress—how it impacts our bodies and how our social standing can make us more or less susceptible. From baboon troops on the plains of Africa, to neuroscience labs at Stanford University, scientists are revealing just how lethal stress can be. Research tells us that the impact of stress can be found deep within us, shrinking our brains, adding fat to our bellies, even unraveling our chromosomes. Understanding how stress works can help us figure out ways to combat it and how to live a life free of the tyranny of this contemporary plague.

In Stress: Portrait of a Killer, scientific discoveries in the field and in the lab prove that stress is not just a state of mind, but something measurable and dangerous.

Hannah Fry trained as a mathematician, and completed her PhD in fluid dynamics in early 2011. After a brief period working as an aerodynamicist in the motorsport industry, she came back to UCL to work on a major interdisciplinary project in complexity science. The project spans several departments, including Mathematics and the Centre for Advanced Spatial Analysis, and focuses on understanding global social systems — such as Trade, Migration and Security. Hannah’s research interests revolve around creating new mathematical techniques to study these systems, with recent work including studies of the London Riots and Consumer Behaviour.

Talk: Is life really that complex?
Recently scientists have begun to appreciate that many of the mechanisms inherent in our social systems have analogies in seemingly unrelated problems. The movement of a crowd, for instance, can be understood using techniques traditionally applied to the flow of a fluid, and the uptake of a new technology can be predicted using knowledge of how disease spreads.
By exploiting these analogies, a new field is emerging at the interface between social sciences and mathematics, the potential of which I hope to illustrate using a mathematical model of the London Riots. Our approach can demonstrate why certain areas of the city were at higher risk than others and help determine which policing strategies may have resulted in a swifter resolution to the unrest.
We will discuss how social modelling can provide a greater understanding of our society, and help design better systems for all: from healthcare to policing and policy.

Throughout human evolution, multiple versions of humans co-existed. Could we be mid-upgrade now?

At TEDxSummit, Juan Enriquez sweeps across time and space to bring us to the present moment — and shows how technology is revealing evidence that suggests rapid evolution may be under way.
