Mary Lou Jepsen: Could future devices read images from our brains?
Why you should listen
Mary Lou Jepsen is the head of the Display Division at Google [x]. Previously she has founded or co-founded 4 different startups and served as the CTO or CEO at all of them. In 2005, with Nicholas Negroponte, she co-founded One Laptop per Child (OLPC) to build affordable computers for the world’s poorest children. As CTO she invented, architected and delivered to high-volume production a machine that the titans of technology believed was impossible to make. Dr. Jepsen then founded Pixel Qi Corp. in 2008 in an attempt to transform a broken display component industry into an innovation engine. In the past she has been a professor at MIT, the CTO of Intel’s Display Division and a globe-trotting high-tech media artist. She has been ranked in the top 50 female computer scientists of all time, and Time Magazine inducted her into its “Time 100″ as one of the 100 most influential people in the world.

Alex Wissner-Gross: A new equation for intelligence
Is there an equation for intelligence? Yes. It’s F = T ∇ Sτ. In a fascinating and informative talk, physicist and computer scientist Alex Wissner-Gross explains what in the world that means. (Filmed at TEDxBeaconStreet.)
Alex Wissner-Gross applies science and engineering principles to big (and diverse) questions, like: “What is the equation for intelligence?” and “What’s the best way to raise awareness about climate change?”
WHY YOU SHOULD LISTEN TO HIM?
Alex Wissner-Gross is a serial big-picture thinker. He applies physics and computer science principles to a wide variety of topics, like human intelligence, climate change and financial trading.
Lately Wissner-Gross started wondering: Why have we searched for so long to understand intelligence? Can it really be this elusive? His latest work posits that intelligence can indeed be defined physically, as a dynamic force, rather than a static property. He explains intelligence in terms of causal entropic forces, ultimately defining it as “a force to maximize future freedom of action.”
Wissner-Gross is a fellow at the Harvard Institute for Applied Computational Science and a research affiliate at the MIT Media Lab. He has a Ph.D. in physics from Harvard and bachelor’s degrees in physics, electrical science and engineering, and mathematics from MIT.

Sandra Aamodt: Why dieting doesn’t usually work
In the US, 80% of girls have been on a diet by the time they’re 10 years old. In this honest, raw talk, neuroscientist Sandra Aamodt uses her personal story to frame an important lesson about how our brains manage our bodies, as she explores the science behind why dieting not only doesn’t work, but is likely to do more harm than good. She suggests ideas for how to live a less diet-obsessed life, intuitively.
Sandra Aamodt explores the neuroscience of everyday life, examining new research and its impact on our understanding of ourselves.
WHY YOU SHOULD LISTEN TO HER?
Sandra Aamodt is a neuroscientist and science writer, who takes the complexities of neuroscience research and whips them into fun reads that give people a better understanding of their minds and behavior. Her books Welcome to Your Brain and Welcome to Your Child’s Brain (both written with Sam Wang) are designed to bring neuroscience to a general audience, and they’ve both been widely translated. Aamodt’s science writing has also appeared in The New York Times, The Washington Post, El Mundo and the Times of London.
From 2003 to 2008, Aamodt was the editor-in-chief of Nature Neuroscience, a leading scientific journal in the field of brain research. She brings a significant scientific background to the task of explaining new research without creating neurobunk. During her career, she has read over five thousand neuroscience papers, and written many editorials on science policy.

Peter Doolittle: How your “working memory” makes sense of the world
“Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it.” In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance — and limitations — of your “working memory,” that part of the brain that allows us to make sense of what’s happening right now.
Peter Doolittle is striving to understand the processes of human learning.
WHY YOU SHOULD LISTEN TO HIM?
Peter Doolittle is a professor of educational psychology in the School of Education at Virginia Tech, where he is also the executive director of the Center for Instructional Development and Educational Research. He teaches classes such as Cognition and Instruction, Constructivism and Education, Multimedia Cognition and College Teaching, but his research mainly focuses on learning in multimedia environments and the role of “working memory.”
Doolittle has taught educational psychology around the world. He is the executive editor of the International Journal of Teaching and Learning in Higher Education and the co-executive editor of the International Journal of ePortfolio.
Suzana Herculano-Houzel: What is so special about the human brain?
The human brain is puzzling — it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why? Neuroscientist Suzana Herculano-Houzel puts on her detective’s cap and leads us through this mystery. By making “brain soup,” she arrives at a startling conclusion.
Suzana Herculano-Houzel shrunk the human brain by 14 billion neurons — by developing a new way to count them.
WHY YOU SHOULD LISTEN TO HER?
How many neurons make a human brain? For years, the answer has been (give or take) 100 billion. But neuroscientist Suzana Herculano-Houzel decided to count them herself. Her research approach involved dissolving four human brains (donated to science) into a homogeneous mixture — in her lab at the Institute of Biomedical Sciences in Rio de Janeiro, they call it “brain soup.” She then took a sample of the mix, counted the number of cell nuclei belonging to neurons, and scaled that up. Result: the human brain has about 86 billion neurons, 14 billion fewer than assumed — but intriguingly, far more than other animals, relative to brain size.
She suggests that it was the invention of cooking by our ancestors — which makes food yield much more metabolic energy — that allowed humans to develop the largest primate brain. She’s now working on elephant and whale brains to test her hypothesis.
