What We Still Don't Know: "Are We Real?" A mind-boggling journey to post-human life

Series from Channel 4 featuring Sir Martin Rees.

 

There is a fundamental chasm in our understanding of ourselves, the universe, and everything. To solve this, Sir Martin takes us on a mind-boggling journey through multiple universes to post-biological life. On the way we learn of the disturbing possibility that we could be the product of someone elses experiment.

Michio Kaku: What's the Fate of the Universe? It's in the Dark Matter

Why should you bother to wake up tomorrow knowing that we're all going to die billions and billions of years from now when the universe turns to absolute zero, when the stars blink out, when we have nothing but neutron stars and black holes? Dr. Kaku says that billions of years from now we may be able to move to a different universe.

Photons to Bits and Beyond: The Science & Technology of Digital

The Yale School of Engineering & Applied Science presents the 2011 Victor M. Tyler Distinguished Lectureship in Engineering with Eric Fossum, Professor of Engineering in Dartmouth's Thayer School and a consultant to Samsung Electronics' Semiconductor R&D Center. Dr. Fossum, who earned a PhD in electrical engineering from Yale in 1984, is one of the world's leading solid-state image sensor device physicists, best known for inventing the CMOS image sensor. His "camera-on-a-chip" technology is used in nearly all camera phones and webcams, digital-still cameras, high-speed motion capture cameras, automotive cameras, dental x-ray cameras, and swallowable pill cameras.

 

An entrepreneur as well as inventor, Fossum's transfer of his own IP portfolio to industry has yielded one of Caltech's greatest licensing revenue streams, and he has served as CEO of two successful high-tech companies. His work was included on Reuters' list of "Baby Boomer Inventions that Changed the World," and Forbes calls him an inventor who has "changed your life."

The Meissner effect - Is levitation the future of travel?

In this video Prof Robin Grimes and Dr Catherine Zentile demonstrate the spectacular world of quantum levitation using superconductivity and the Meissner Effect. We've all heard about solids, liquids and gases but did you know that there are at least 6 states of matter? Superconductors are one such state. Just as when we freeze water we're going from a liquid to a solid, in a similar way, when we cool down some peculiar materials we move from a 'normal' solid to a superconductor. But be warned! Even for the absurdly named 'high temperature' superconductors this transition happens at below -180 °C so lots of liquid nitrogen is needed to cool it down! After the transition the material looks the same to the naked eye -- it is its properties that become strange. Firstly, it loses ALL electrical resistance (hence the name superconductor). But being a perfect conductor isn't the property that makes 'superconductors' a new state of matter. Their uniqueness comes from the fact that they exhibit the Meissner effect which means that they expel any small magnetic fields nearby. Add a bit of quantum trapping and this allows superconductors to spectacularly levitate above magnets as we see in this video! And it is this exciting property that has been proposed by scientists and engineers as the technology to make levitating trains of the future a reality!

[VIDEO] Michio Kaku: The Universe in a Nutshell

What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays.

Seth Lloyd's Lecture about Quantum Limits to the Measurement of Spacetime Geometry

Seth Lloyd's Lecture about Quantum Limits to the Measurement of Spacetime Geometry | Science-Videos | Scoop.it

This talk analyzes the limits that quantum mechanics imposes on the accuracy to which spacetime geometry can be measured. By applying the fundamental physical bounds to measurement accuracy ensembles of clocks and signals, as in the global positioning system, I present a covariant version of the quantum geometric limit, which states that the total number of ticks of clocks and clicks of detectors that can be contained in a four volume of spacetime of radius R and temporal extent is less than or equal to RT divided by the Planck length times the Planck time. The quantum geometric bound limits the number of events or 'ops' that can take place in a four-volume of spacetime and is consistent with and complementary to the holographic bound which limits the number of bits that can exist within a three-volume of spacetime.

Do we need String Theory for Quantum Gravity? - Lance Dixon (SETI Talks)

The strong, weak, and electromagnetic interactions all have consistent, relativistic and quantum mechanical descriptions in terms of pointlike particles, but Einstein's theory of gravitation has long resisted a similar treatment, because of severe ultraviolet divergences. String theory solves these problems, but it introduces a new length scale, perhaps 16 orders of magnitude below what can be tested experimentally.


Dr. Dixon will describe recent theoretical progress in showing that a particular pointlike theory of gravity, called N=8 supergravity, might also be quantum mechanically consistent. In particular, N=8 supergravity has been shown explicitly to have no ultraviolet divergences in perturbation theory through the four-loop order. Dr. Dixon will also discuss the possible implications of these results.

By 2019, the experimental reactor ITER will attempt to generate 500 MW of fusion power from 50 MW input

Listen as Stefano Concezzi and Michael Cerna talk about making energy from fusion. Fusion is happening all around us. By 2019, the ITER experimental reactor will attempt to generate 500 megawatts of fusion power from 50 megawatts of power consumed. In order to accurately measure plasma shape and position, critical to the eventual confinement of plasma at 150-million degrees, it takes a specialized real-time and multicore system. To simulate the hardware in the loop is even more difficult. See how NI LabVIEW and NI PXI help prove out this technology.

The ATLAS Experiment Movie - CERN Document Server | Science-Videos | Scoop.it

This award winning film gives a glimpse behind the scenes of building the ATLAS detector.

 

This film asks:

 

Why are so many physicists anxious to build this apparatus?
Where does mass come from?

Why does the Universe have so little antimatter?
Are there extra dimensions of space hidden from our view?
Is there an underlying theory to find?

Major surprises are likely in this unknown part of physics.
