Give and Take: A Revolutionary Approach to Success

Adam Grant (photo by Michael Kamber)

IN THIS LECTURE, based on his book on the psychology of human interactions, organizational psychologist Dr. Adam Grant (the youngest tenured professor at the Wharton Business School) argues that as much as hard work, talent and luck, the way we choose to interact with other people defines our success or failure. Give and Take demolishes the “me-first” worldview and shows that the best way to get to the top is to focus not on your solo journey but on bringing others with you. Grant reveals how one of America’s best networkers developed his connections, why a creative genius behind one of the most popular shows in television history toiled for years in anonymity, how a basketball executive responsible for multiple draft busts turned things around, and how we could have anticipated Enron’s demise four years before the company collapsed—without ever looking at a single number.

To Boldly Go…Well, You Know:
NASA’s Dawn Mission to the Asteroid Belt

Marc Rayman

The ambitious Dawn mission, launched in September 2007, is one of NASA’s most remarkable ventures into the solar system. The spacecraft has recently completed a spectacular exploration of Vesta and is now traveling to Ceres; these were among the last uncharted worlds in the inner solar system prior to Dawn. They are the two most massive residents of the main asteroid belt. Ceres is so large that it is included in the category of dwarf planets, along with Pluto. Remnants from the time that planets were formed, Ceres and Vesta hold clues that will help scientists understand the dawn of the solar system. Dawn orbited Vesta from July 2011 to September 2012 and returned astonishing views of this fascinating world. It is the only spacecraft ever to orbit an object in the asteroid belt. Such a mission would be impossible without the use of ion propulsion, a technology that has mostly been in the domain of science fiction, but which was tested extensively on the Deep Space 1 mission, paving the way for Dawn. Dr. Marc Rayman, Dawn’s Chief Engineer and Mission Director at JPL, will describe the Dawn mission and its use of ion propulsion as well as its two exotic destinations. He will also share the excitement and profundity of controlling a spacecraft in deep space.

Louder Than Words: The New Science
of How the Mind Makes Meaning

Benjamin Bergen (photo by Keegan Uhl)

In this Lecture, based on his book, U.C. San Diego cognitive psychologist Benjamin K. Bergen draws together research in psychology, linguistics, and neuroscience to offer a new theory of how our minds make meaning. When we hear words and sentences, we engage the parts of our brain that we use for perception and action—repurposing evolutionarily older networks—to create mental simulations. Embodied simulation, as it’s called, is the reason why it takes time to travel over distance, even in our mind’s eye; why it’s possible for us to become better baseball players by imagining a well-executed swing; and why it’s so hard to talk on cell phones while we’re driving on the highway. Rather than merely calling up abstract ideas to understand language, as others previously argued, our brains engage in a creative act to construct rich mental worlds in which we see, hear, and feel.

The Visioneers: How a Group of Elite Scientists Pursued Space Colonies, Nanotechnologies, and a Limitless Future

Dr. W. Patrick McCray (photo by Brian W Robb)

In 1969, Princeton physicist Gerard O’Neill began looking outward to space colonies as the new frontier for humanity’s expansion. A decade later, Eric Drexler, an MIT-trained engineer, turned his attention to the molecular world as the place where society’s future needs could be met using self-replicating nanoscale machines. These modern utopians predicted that their technologies could transform society as humans mastered the ability to create new worlds, undertook atomic-scale engineering, and, if truly successful, overcame their own biological limits. In this lecture, based on the book by the same name, Patrick McCray traces how these visioneers blended countercultural ideals with hard science, entrepreneurship, libertarianism, and unbridled optimism about the future. But the visioneers were not immune to failure—or to the lures of profit, celebrity, and hype. O’Neill and Drexler faced difficulty funding their work and overcoming colleagues’ skepticism, and saw their ideas co-opted and transformed by Timothy Leary, the scriptwriters of Star Trek, and many others. Ultimately, both men struggled to overcome stigma and ostracism as they tried to unshackle their visioneering from pejorative labels like “fringe” and “pseudoscience.” The Visioneers provides a balanced look at the successes and pitfalls they encountered, the dangers that can plague exploratory science, and the importance of radical new ideas that inspire us to support cutting-edge research into tomorrow’s technologies.

The World Until Yesterday: What Can We Learn from Traditional Societies?

Dr. Jared Diamond

The mega-bestselling author of Guns, Germs, and Steel and Collapse, Dr. Jared Diamond surveys the differences between “traditional” societies and industrial or post-industrial societies, with an eye to the question: what can we learn from the former that can make the world we live in a better place for all of us? Today, citizens of industrial states take for granted metal, writing, airplanes, police and government, overweight people, meeting strangers without fear, heterogeneous populations, and so on. But all those features of modern human societies are relatively new in human history. For most of our past, human societies had none of these things. Today’s traditional societies are in many respects a window onto the human world as it was until a mere yesterday, measured against a time scale of the 6,000,000 years of human evolution. Those societies show us pieces of how all of our ancestors lived for tens of thousands of years. Traditional lifestyles are what shaped us and caused us to be what we are today; all human societies have been traditional for far longer than any society has been modern. Thus, traditional represent thousands of natural experiments in how to construct a human society. They have come up with thousands of solutions to human problems, solutions different from those adopted by our own modern societies. Diamond gives us a first-hand picture of the human past as it has been for millions of years and considers what the differences between that past world and our present one mean for our collective future.
