This extraordinary documentary poses questions that still resonate today - will the machines we build to save humanity end up replacing us or even destroying us? Historian Simon Schaffer tells the stories behind some of the most sensational engineering wonders of past centuries. Images of designs and remnants spark questions that cut to the heart of our ever-advancing technological civilization.

what is everything, and what is nothing? Professor Jim Al-Khalili explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness. EVERYTHING: what the universe might actually look like and the remarkable stories of the men and women who discovered the truth about the cosmos. NOTHING: science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim Al-Khalili can prove it.

Documentary presented by Professor Simon Schaffer which charts the amazing and untold story of automata - extraordinary clockwork machines designed hundreds of years ago to mimic and recreate life. The film brings the past to life in vivid detail as we see how and why these masterpieces were built. Travelling around Europe, Simon uncovers the history of these machines and shows us some of the most spectacular examples, from an entire working automaton city to a small boy who can be programmed to write and even a device that can play chess. All the machines Simon visits show a level of technical sophistication and ambition that still amazes today.

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?
