In the aftermath of Hiroshima, a group of scientists vowed never to turn knowledge into weapons again, and from that promise, CERN was born. Deep underground, researchers from nations in conflict have worked side by side for decades, driven by curiosity and shared wonder. For 70 years, CERN has stood as an act of hope, a place where collaboration transcends borders, even as the world above grows more divided. Blending poetry, music and rare archival footage of nuclear physicist Robert Oppenheimer with remarkable access to the Large Hadron Collider, the film explores how science, politics and culture collide.

For hundreds of years, psychiatry has treated voices and hallucinations as an enemy - regarding them as 'insanity' or 'madness' and seeing them as something to be quashed and even frightened of. But today, new scientific and psychological insights into how the brain works are leading to a radical rethink on what such experiences are - and how they should be treated. Horizon follows three people living with voices, hallucinations and paranoia, to explore what causes this kind of phenomena. Providing a rare first-hand insight into these experiences, they reveal just what it is like to live with them day to day. They examine the impact of social, biological and environmental influences on conditions traditionally associated with insanity, such as schizophrenia and psychosis, and within the film they look at how new ways of understanding the brain are leading to a dramatic change in treatments and approaches, and examine whether targeting the root causes of psychosis can lead to recovery. Above all, they try to uncover why it happened to them - and whether it could happen to you.

Join NOVA 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. Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists, and engineers, follow math from Pythagoras to Einstein and beyond. It all leads to the ultimate riddle: Is math a human invention or the discovery of the language of the universe?
One hundred green-eyed logicians have been imprisoned on an island by a mad dictator. Their only hope for freedom lies in the answer to one famously difficult logic puzzle. Can you solve it? Alex Gendler walks us through this green-eyed riddle.

An algorithm is a method of solving problems both big and small. Though computers run algorithms constantly, humans can also solve problems with algorithms. David J. Malan explains how algorithms can be used in seemingly simple situations and also complex ones.
Kicking off the lectures with a mind-boggling stunt to prove how counterintuitive our gut instincts can be, Hannah launches into a lecture full of daring live experiments and surprising discoveries. From predicting the chance of snow at Christmas to dodging erupting volcanoes with Prof Chris Jackson, Hannah explores whether we really can predict the future. She meets the maths gurus behind Liverpool Football Club's winning streak to spill the beans on how analysing the numbers can give a team an edge in the Premier League, and reveals the tricks to perfecting your Christmas cracker pull to win the prize every time. Hannah also gathers tips from mind-performance coach Dr Michael Gervais, the 'secret weapon' crafting Olympic athletes' lucky mindsets, and the man responsible for Felix Baumgartner's jump from space, when 'first time lucky' meant life or death. Enrolling the help of maths comedian Matt Parker for the pinnacles of the lecture, the duo find order in unruly crowds, and whittle the audience down to the luckiest person in a series of challenges, before finally putting them to the test to prove whether they truly are one in a million. Using a host of maths tricks - from probability to game theory - Hannah discovers if we can in fact make our own luck, and ultimately shares the secrets to help us all lead luckier lives.

Deception is an integral part of human nature and it is estimated we all lie up to nine times a day. But what if we created a world in which we couldn't lie? In a radical experiment, pioneering scientists from across Europe have come together to make this happen. Brand new technology is allowing them to rig three British people to make it impossible for them to lie undetected. Then they will be challenged to live for a whole week without telling a single lie. It is a bold social experiment to discover the role of deception in our lives - to investigate the impact lying has on our mental state and the consequences of it for our relationships, and to ask whether the world would be a better or worse place if we couldn't lie.
