História

Janna Levin is an American theoretical cosmologist and an associate professor of physics and astronomy at Barnard College. She earned a PhD in theoretical physics at the Massachusetts Institute of Technology in 1993, and a Bachelor of Science in astronomy and physics with a concentration in philosophy at Barnard College in 1988, where she graduated Phi Beta Kappa. Much of her work deals with looking for evidence to support the proposal that our universe might be finite in size due to its having a nontrivial topology. Other work includes black holes and chaos theory. She joined the faculty at Barnard College in January 2004 and is currently the recipient Tow Professor grant.

Uma Viagem ao Infinito

Self

Nomes importantes da matemática, da física de partículas e da cosmologia mergulham no infinito e em suas desconcertantes implicações para o universo.

Timelapse of the Future: A Journey to the End of Time

Narrator (archive sound)

How's it all gonna end? This experience takes us on a journey to the end of time, trillions of years into the future, to discover what the fate of our planet and our universe may ultimately be. We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.

Black Hole Apocalypse

Presenter

Astrophysicists show how black holes might hold answers to how the universe evolved, leading to life on Earth and, ultimately, the human race.

NOVA: The Great Math Mystery

Self

NOVA leads viewers on a mathematical mystery tour -- a provocative exploration of math's astonishing power across the centuries. We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson and the successful landing of rovers on Mars. But where does math get its power? Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists and engineers, follows math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind's clever trick or the language of the universe?
