Lens of Time: Secrets of Schooling

Collective behavior is embodied in swarms of insects, flocks of birds, herds of antelope, and schools of fish. In each of these cases, individuals move through their environment and respond to threats and opportunities almost simultaneously, forming an undulating enclave that seems to operate as a single entity. Such coordinated movement requires the rapid and efficient transfer of information among individuals, but understanding exactly how this information spreads through the group has long eluded scientists. Studying this behavior in schools of fish has been incredibly challenging, because the cues that drive it occur at lightening speed, come from multiple directions and sources, and of course because all of it takes place underwater. Now, Iain Couzin and his colleagues at the Max Planck Institute for Ornithology at the University of Konstanz, Germany are using new observation techniques and technologies—including high-speed video, motion-tracking software, and advanced statistical modeling—to reveal the mysterious mechanics of schooling fish. Their findings may shed light on the evolution and benefits of collective behavior across the animal kingdom.

Your brain hallucinates your conscious reality

Right now, billions of neurons in your brain are working together to generate a conscious experience — and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we’re all hallucinating all the time; when we agree about our hallucinations, we call it “reality.” Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

Don’t fear intelligent machines. Work with them

We must face our fears if we want to get the most out of technology — and we must conquer those fears if we want to get the best out of humanity, says Garry Kasparov. One of the greatest chess players in history, Kasparov lost a memorable match to IBM supercomputer Deep Blue in 1997. Now he shares his vision for a future where intelligent machines help us turn our grandest dreams into reality.
