Project Greenglow – The Quest for Gravity Control

The story of an extraordinary scientific adventure – the attempt to control gravity. The dream of flying cars and journeys to the stars no longer seems quite so distant

This is the story of an extraordinary scientific adventure – the attempt to control gravity. For centuries, the precise workings of gravity have confounded the greatest scientific minds – from Newton to Faraday and Einstein – and the idea of controlling gravity has been seen as little more than a fanciful dream. Yet in the mid 1990s, UK defence manufacturer BAE Systems began a ground-breaking project code-named Greenglow, which set about turning science fiction into reality. On the other … Ler mais

Inside CERN

Horizon documents an extraordinary story in particle physics, following CERN's scientists as they hunt for the elusive signals that would prove if there is a new particle

With exclusive behind-the-scenes access, Horizon follows the highs and lows of an extraordinary story in particle physics. In June 2015, teams at CERN started running the large hadron collider at the highest energy ever. Rumours quickly emerged that they were on the brink of a huge discovery. A mysterious bump in some data suggested a first glimpse of a brand new particle that could change our understanding of how the universe works.

A new particle could hint at extra dimensions … Ler mais

Tesla

Visionary or Madman?

Meet Nikola Tesla, the genius engineer and tireless inventor whose technology revolutionized the electrical age of the 20th century. Regarded by many historians as an eccentric genius, Tesla gained international fame for his invention of a system of alternating current that made possible the distribution of electricity over vast distances and is the basis for the electrical grid that powers 21st century life.

But the visionary Tesla imagined much more — robots, radio, radar, remote control, the wireless … Ler mais

How to Build a Time Machine

Horizon meets scientists working on the cutting edge of discovery - people who may discover how to build wormholes, manipulate entangled photons or build functioning time crystals

Time travel is not forbidden by the laws of nature, but to build a time machine, we would need to understand more about those laws and how to subvert them than we do now. And every day, science does learn more.

In this film Horizon meets the scientists working on the cutting edge of discovery – men and women who may discover how to build wormholes, manipulate entangled photons or build fully functioning time crystals. In short, these scientists may … Ler mais

POWERS OF TEN

Powers of ten and the relative size of things in the Universe

Powers of Ten is one of the Eameses’ best-known films. Since it was produced in 1977, it has been seen by millions of people both nationally and internationally. As with A Communication Primer and 2n (a 2-minute Peep Show from the exhibition, Mathematica), in this film, Charles and Ray employed the system of exponential powers to visualize the importance of scale.

When the Eameses came across the 1957 book by Kees Boeke, Cosmic View: The Universe in Forty Jumps, … Ler mais

Einstein’s Quantum Riddle

Join scientists as they grab light from across the universe to prove quantum entanglement is real

Over the past century, scientists have made huge strides in understanding the mind-bending rules that govern the microworld of atoms and subatomic particles. But these rules, called quantum mechanics, contain one particularly bizarre, unexplained phenomenon: quantum entanglement.

Imagine two subatomic particles that mirror changes in each other instantaneously over any distance – apparently without communicating. Einstein called it “spooky action at a distance” and although no one can explain how it works, scientists have already begun to harness … Ler mais

Prediction by the Numbers

Discover why some predictions succeed and others fail as experts forecast the future

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the Internet, and “big data,” the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty?

In a fascinating, fast-paced investigation, NOVA takes viewers from the glitz of casinos and TV game shows to the life-and-death stakes of storm … Ler mais

Inside Einstein’s Mind: The Enigma of Space and Time

The story of the most elegant and powerful theory in science, Albert Einstein's general relativity. It takes us inside the head of Einstein to witness how his idea evolved.

The story of the most elegant and powerful theory in science – Albert Einstein’s general relativity.

When Einstein presented his formidable theory in November 1915, it turned our understanding of gravity, space and time completely on its head. Over the last 100 years, general relativity has enabled us to trace the origins of the universe to the Big Bang and to appreciate the enormous power of black holes.

To mark the 100th anniversary of general relativity, this film … Ler mais

The Origami Revolution

Engineers are using origami to design drugs, micro-robots, and future space missions

The centuries-old tradition of folding two-dimensional paper into three-dimensional shapes is inspiring a scientific revolution. The rules of folding are at the heart of many natural phenomena, from how leaves blossom to how beetles fly. But now, engineers and designers are applying its principles to reshape the world around us—and even within us, designing new drugs, micro-robots, and future space missions.

With this burgeoning field of origami-inspired-design, the question is: can the mathematics of origami be boiled down to one … Ler mais
