Theoretical physicist Michio Kaku describes some of the inventions he thinks will appear in the coming century — including Internet-ready contact lenses, space elevators and driverless cars — in his book Physics of the Future.
Quantum computing genius and Oxford don David Deutsch is a thinker of such scale and audaciousness he can take your breath away. His bottom line is simple and breathtaking all at once.
It’s this: human beings are the most important entities in the universe. Or as Deutsch might have it, in the “multiverse.” For eons, little changed on this planet, he says. Progress was a joke. But once we got the Enlightenment and the scientific revolution, our powers of inquiry and discovery became infinite. Without limit.
On this episode of “Mustang Physics,” Matt Bellis (Stanford University) discusses his spontaneous collaboration with both physicists and non-physicists that has turned particle collision data into music with the goal of giving new communities an experience with physics data. “Mustang Physics” is your gateway into the world of physics and the lives and thoughts of physicists.
Matt Bellis is a post-doctoral researcher at Stanford University. He works on the BaBar Experiment at the SLAC National Accelerator Laboratory. He presented the SMU Physics Department Seminar on March 7, 2011, where he discussed his work on the search for fundamental symmetry violations that might explain our asymmetric cosmos. He spoke with me about his effort to use particle physics data to produce music. This effort would allow whole new communities to experience and use particle physics data.
Co-presented by The Philadelphia Science Festival Introduced by Dennis Wint, president and chief executive officer of The Franklin Institute Recognized for his groundbreaking discoveries in superstring theory, Brian Greene hosted the Public Broadcasting Service’s NOVA series based on his book, The Elegant Universe. A professor of mathematics and physics at Columbia University, he is also the author of The Fabric of the Cosmos and Icarus at the Edge of Time. He is well-known for making complex scientific principles accessible to general audiences. According to a reviewer for Publishers Weekly, the strength of his books lies ”in Greene’s unparalleled ability to translate higher mathematics and its findings into everyday language and images, through adept use of metaphor and analogy, and crisp, witty prose." In The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos, Greene shows how a range of different multiverse proposals emerges from theories developed to explain observations of both subatomic particles and the dark depths of space, featuring doppelgängers, strings, branes, quantum probabilities, holographs, and simulated worlds. Brian Greene will be interviewed by Dr. Steve Snyder, vice president of programs and exhibitions at The Franklin Institute. (recorded 4/28/2011)
Black Holes seem to have bad press that is largely undeserved. This lecture with professor Ian Morison explains what Black Holes are, and how we can discover them even through they can’t be seen.
This program was recorded in collaboration with Gresham College, on October 27, 2010.
Gresham Professor of Astronomy Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford, he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester.
Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom.
At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory’s website.
It is possible that there are many other universes that exist parallel to our universe. Theoretical physicist Brian Greene, author of The Elegant Universe, explains how that’s possible in the new book, The Hidden Reality.
The idea of the space elevator has been around for over a century. But in recent years teams of scientists and engineers have been actively working on the concept. So could the elevator become a reality? Or is it still a case of science-fiction?
Deep beneath the border of France and Switzerland, the world’s most massive physics machine is sending subatomic particles smashing into each other at speeds nearing the speed of light. Physicists working with the 17-mile-long Large Hadron Collider hope it will help solve some of the universe’s mysteries.
But first, researchers must overcome two very mundane hurdles: how to handle all of the data the LHC generates, and how to get non-scientists to care.
One physicist has a novel way to solve both problems: sound.

- Moments of Genius: Anton van Leeuwenhoek – the birth of microbiology
- Microbiology today - using antibodies against cancer

- Science Hack Day San Francisco
Sometimes a fresh pair of eyes on a problem can give us an important new perspective on it, but it is not often that scientists veer out of their very specialised fields to see their work through other people’s eyes. But 100 people, from a mix of different backgrounds, have just descended on San Francisco for Science Hack Day. They joined forces, shared skills, and spent 24-hours together, in the hope of finding new ways to use established technologies, and new ways to get information from existing data. Kate Arkless went to find out what a Science Hack Day is all about.
