Homo Techno -
searching: our quest for meaning in the age of science

Part 3, "Homo Techno," features stories - including that of a paralyzed former gang member who risked his brain to advance medical science - that prompt Lightman to think deeply about how advances in science and technology will impact our future evolution into what will perhaps be a new species: "Homo Techno" - part human and part machine. What essential human qualities will we want to preserve? As both a physicist and an essayist, Lightman is a rare talent. After years on the faculties of Harvard and the Massachusetts Institute of Technology, Lightman's first novel, Einstein's Dreams, became an international best-seller. Co-written and directed by award-winning public television science producer Geoff Haines-Stiles (Carl Sagan's COSMOS, NOVA's "Is Anybody Out there," and Childhood), SEARCHING is filmed in Ultra HD format worldwide, and features state-of-the-art astronomical computer graphics along with a wide range of innovative story-telling techniques.

About Searching: Our Quest for Meaning in the Age of Science:

In SEARCHING: OUR QUEST FOR MEANING IN THE AGE OF SCIENCE, physicist and best-selling author Alan Lightman investigates how key findings of modern science help us find our bearings in the cosmos.

What do these new discoveries tell us about ourselves, and how do we find meaning in them? Throughout the highly cinematic three-part series, Alan takes viewers along on his journey of exploration - from prehistoric paintings in a French cave to a giant subatomic particle accelerator in Switzerland; from a Harvard laboratory where biologists are attempting to create living cells from scratch to the gravitational wave observatories that first detected the collisions of black holes; and to the quiet of a Buddhist temple.

We travel from the infinity of the small to the infinity of the large, meeting with the co-discoverer of one of the most distant galaxies yet known.

Across the series, Alan also interviews brain scientists, physicists, astronomers, philosophers, ethicists and faith leaders who offer contrasting perspectives on the interplay between contemporary scientific research and the humanities.

Adding to the diversity of perspectives is a dynamic conversation with Bina48, the world's most advanced humanoid robot.
