The video game industry is a global phenomenon. There are over 1.2 billion gamers across the planet, with sales projected soon to pass $100 billion per year. But their very popularity fuels the controversy that surrounds them. They frequently stand accused of corrupting the young - of causing violence and addiction. But is this true? Horizon reveals a scientific community deeply divided. Some are convinced that video games incite aggression. Others insist they have no effect whatsoever on real-world violence. But away from the controversy, there is a growing body of evidence that suggests video games may help keep the brain sharp, and could soon revolutionise how we combat mental decline as we age.
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?
