Dennis Wildfogel: How Big Is Infinity?

Using the fundamentals of set theory, explore the mind-bending concept of the “infinity of infinities” — and how it led mathematicians to conclude that math itself contains unanswerable questions.

Hannah Fry: Is life really that complex?

  TED presents Hannah Fry who in this accessible talk shows how complex social behavior can be analyzed and perhaps predicted through apt analogies to natural phenomena, like the patterns of a leopard’s spots or the distribution of predators and prey in the wild. Hannah Fry trained as a mathematician, and completed her PhD in fluid dynamics …

Paul Davies: How to Build A Time Machine

SETI Talks presents Paul Davies talking about time travel. Time travel makes great science fiction, but can it really be done? Travel into the future is already a reality, but visiting the past is a much tougher proposition, and may require fantastic resources such as a wormhole in space. Nevertheless, if going back in time …

Boaz Almog: Superconductor levitatation

TED presents Boaz Almog who makes a super-thin 3-inch disk levitate object 70,000 times its own weight. In a riveting demonstration, Almog shows how a phenomenon known as quantum locking allows a superconductor disk to float over a magnetic rail — completely frictionlessly and with zero energy loss.

Donald Sadoway: The missing link to renewable energy

What’s the key to using alternative energy, like solar and wind? Storage — so we can have power on tap even when the sun’s not out and the wind’s not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As …

  Three videos published by CERN in the wake of the discovery of the Higgs Boson; an interview with Peter Higgs and with explanations of the magnitude and relevance of the discovery.  

Bill Gates: Innovating to zero!

Bill Gates unveils his vision for the world’s energy future at TED2010, describing the need for “miracles” to avoid planetary catastrophe and explaining why he’s backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050. Bill Gates on energy: Innovating to zero! [KGVID width=”720″ height=”400″]http://www.ourprg.com/Video/BillGates_2010-480p-en.mp4[/KGVID]

Amory Lovins: A 40-year plan for energy

Energy innovator Amory Lovins shows how to get the US off oil and coal by 2050, $5 trillion cheaper, with no Act of Congress, led by business for profit. The key is integrating all four energy-using sectors—and four kinds of innovation.”
