How Long is a Piece of String?

• December, 2013

Alan Davies attempts to answer the proverbial question: how long is a piece of string? But what appears to be a simple task soon turns into a mind-bending voyage of discovery where nothing is as it seems. An encounter with leading mathematician Marcus du Sautoy reveals that Alan’s short length of string may in fact be infinitely long. When Alan attempts to measure his string at the atomic scale, events take an even stranger turn. Not only do objects appear in many places at once,

Do you know what time it is? – BBC Horizon

• March, 2013

Watch BBC.Horizon.2008.Do.You.Know.What.Time.It.Is.avi in Educational Particle physicist Professor Brian Cox asks, ‘What time is it?’ It’s a simple question and it sounds like it has a simple answer. But do we really know what it is that we’re asking? Brian visits the ancient Mayan pyramids in Mexico where the Maya built temples to time. He finds out that a day is never 24 hours and meets Earth’s very own Director of Time. He journeys to the beginning of time, and goes beyond within the realms of

Quantum Teleportation Goes the Distance

• October, 2012

Record-Breaking Distance of 143 Kilometers Through Free Space An international research team including several scientists from the University of Waterloo has achieved quantum teleportation over a record-breaking distance of 143 kilometres through free space. The experiment saw the successful teleportation of quantum information — in this case, the states of light particles, or photons — between the Canary Islands of La Palma and Tenerife. The breakthrough is a crucial step toward quantum communications via satellite. Unlike the teleportation of solid objects popularized in science fiction,

9/11: Explosive Evidence – Experts Speak Out

Watch 9/11: Explosive Evidence – Experts Speak Out on PBS. See more from KBDI. Over 40 experts in high-rise architecture, structural engineering, metallurgy, chemistry, physics, explosives, and controlled demolition share their professional expertise and insights about the events of 9/11. Additionally, 8 psychological experts discuss why proving controlled demolition of the three World Trade Center skyscrapers can be so difficult for individuals to accept.

Light Created from a Vacuum

• December, 2011

The Casimir Effect Observed in Superconducting Circuit Scientists at Chalmers have succeeded in creating light from vacuum — observing an effect first predicted over 40 years ago. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum. The experiment is based on one of the most counterintuitive, yet, one of the most important principles in quantum mechanics: that vacuum is by no means empty nothingness. In fact, the vacuum is full of
