The Scientific Quest for a Fountain of Youth
 

We’re born, we grow old, we die. It’s a rhythm long considered inevitable. But is it? Or is aging merely a disease awaiting a cure? Will science one day stave off aging or even reverse it? David Sinclair, Elissa Epel, Nir Barzilai, and Laura Niedernhofer join Brian Greene to explore the biology of aging and recent breakthroughs that, according to some, could have people living healthfully to 120 or beyond by the end of this century. 
 

Does Math Reveal Reality?
 

Mathematics has an uncanny ability to describe the physical world. It elegantly explains and predicts features of space, time, matter, energy and gravity. But is this magnificent scientific articulation an invention of the human mind or is mathematics indelibly imprinted upon the substrate of reality? Brian Greene and leading thinkers parse the thorny problems of math’s existence.
 

How does the brain retrieve memories, articulate words, and focus attention? Recent advances have provided a newfound ability to decipher, sharpen, and adjust electrical signals relevant to speech, attention, memory and emotion. Join Brian Greene and leading neuroscientists György Buzsáki, Edward Chang, Michael Halassa, Michael Kahana and Helen Mayberg for a thrilling exploration of how scientists are learning to decode and even repair the brain’s neural networks, in their audacious efforts to reveal the mysteries of the human mind.
