What we touch. What we smell. What we feel. They’re all part of our reality. But what if life as we know it reflects only one side of the full story? Some of the world’s leading physicists think that this may be the case.

Come venture deep inside the world’s biggest physics machine, the Large Hadron Collider. This extraordinary feat of human engineering took 16 years and $10 billion to build, and just weeks ago began colliding particles at energies unseen since a fraction of a second after the big bang.

Can marching ants, schooling fish, and herding wildebeests teach us something about the morning commute? Robert Krulwich guides this unique melding of mathematics, physics, and behavioral science as Mitchell Joachim, Anna Nagurney and Iain Couzin examine the creative and sometimes counter intuitive solutions to one of the modern world’s most annoying problems.

Prominent clashes — both historical and contemporary — have led to the widely held conclusion that science and religion are fundamentally incompatible. Yet, many scientists practice a traditional faith, having found a way to accommodate both scientific inquiry and religious teaching in their belief system.

The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of forefront research.

Why are we drawn to symmetry? Because it provides order in a seemingly chaotic world? Because our brains are the product of the very same laws that yield the flower, the snowflake and the solar system?

Researchers are racing to uncover the implications for the Arctic of rapidly vanishing polar ice – and they’re enlisting help from the very creatures that stand to gain the most from their discoveries: the Narwhal, Bowhead and Beluga whales, three of the most elusive species on Earth.

As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments. Which raises a question familiar to aficionados of The Matrix—might life and the world as we know it be a simulation on a super advanced computer?
