Abstract |
|
In physics, a unified field theory is a type of field theory that allows all of the fundamental forces between elementary particles to be written in terms of a single field. There is no accepted unified field theory yet, and this remains an open line of research. The term was coined by Albert Einstein who attempted to unify the general theory of relativity with electromagnetism. A Theory of Everything is closely related to unified field theory, but differs by not requiring the basis of nature to be fields, and also attempts to explain all physical constants of nature.

A second or third gen PAL VHS dub of a vintage original off-air NTSC VHS tape, then captured and compressed and found on a torrent site. squashed, re-compressed and converted for YouTube. all sorts of obvious video and audio problems, but at least it's here, a special treat from the past. anyone with better source, please drop a comment. Richard Phillips Feynman (May 11, 1918 - February 15, 1988; IPA: /ˈfaɪnmən/) was an American physicist known for expanding the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and particle theory. For his work on quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga; he developed a widely-used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. He assisted in the development of the atomic bomb and was a member of the panel that investigated the Space Shuttle Challenger disaster. In addition to his work in theoretical physics, Feynman has been credited with pioneering the fie... |

Richard Feynman on the appreciation of nature. Video is from 1981 BBC Interview. The interview is also the subject of Feynman's book The Pleasure of Finding Things Out.
I have a friend who's an artist and he's some times taken a view which I don't agree with very well. He'll hold up a flower and say, "look how beautiful it is," and I'll agree, I think. And he says, "you see, I as an artist can see how beautiful this is, but you as a scientist, oh, take this all apart and it becomes a dull thing." And I think he's kind of nutty.
First of all, the beauty that he sees is available to other people and to me, too, I believe, although I might not be quite as refined aesthetically as he is. But I can appreciate the beauty of a flower.
At the same time, I see much more about the flower that he sees. I could imagine the cells in there, the complicated actions inside which also have a beauty. I mean, it's not just beauty at this dimension of one centimeter: there is also beauty at a smaller dimension, the inner structure...also the processes.
The fact that the colors in the flower are evol... |

Customized Y-Shaped Nanotubes Can Compute

Abstract |
|
Researchers at UC San Diego and Clemson University have discovered that specially synthesized carbon nanotube structures exhibit electronic properties that are improved over conventional transistors used in computers. In a paper published* in the September issue of Nature Materials and released online on August 14, UCSD Mechanical and Aerospace Engineering professors Prabhakar Bandaru and Sungho Jin, graduate student Chiara Daraio, and Clemson physicist Apparao M. Rao reported that Y-shaped nanotubes behave as electronic switches similar to conventional MOS (metal oxide semiconductor) transistors, the workhorses of modern microprocessors, digital memory, and application-specific integrated circuits. |

Abstract |
|
For decades, time travel lay beyond the fringe of respectable science. In recent years, however, the topic has become something of a cottage industry among theoretical physicists. The motivation has been partly recreational--time travel is fun to think about. But this research has a serious side, too. Understanding the relation between cause and effect is a key part of attempts to construct a unified theory of physics. If unrestricted time travel were possible, even in principle, the nature of such a unified theory could be drastically affected. |

Abstract |
Scientists at the University of Bristol are turning to nature in their attempts to further their research into Nano-science.
Nano-science is the study of structures and properties at the nano-metre scale - a millionth of a millimetre - and the principle research tool is the Atomic Force Microscope. By looking at the ways in which insects "hear" very faint vibrations, the researchers at Bristol have been able to apply these techniques to Atomic Force Microscopes, significantly improving the sensitivity of these instruments, making it possible to record molecular structure with increased accuracy.
And at the nearby University of Bath they're applying Nano-science to investigate new lighting technology which could recreate natural sunlight in offices and homes, potentially saving billions on energy bills. Known as Solid State Lighting, researchers now estimate that in the next 20 years 90 per cent of the world's lighting will be provided by this technology.
Nano-science may be about the smallest things but its impact on our future will be very great indeed. |

Abstract |
|
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. In acoustics, reflection causes echoes and is... |

Abstract |

Dr Anderson's patent on Extracorporeal heart can be found here From Youtube - The video demonstrates the unique nature of the heart as a non-sucking pump, whose output is controlled by systemic factors, as opposed to pumps (such as standard roller pumps) that suck to fill, whose output is controlled by pump factors. It also shows the determinative effects of Mean Vascular Pressure, Inlet Impedance, and the critical role of the atrium on cardiac output. The resulting understanding is far more illuminating of the actual determinants of cardiac output than the emphasis on concepts like "stroke rate times stroke volume," preload, afterload, and contractility that dominates many basic physiology courses. Robert M. Anderson, MD (1920-2010) was Associate Professor of Surgery and Associate Dean of the University of Arizona College of Medicine in Tucson, Arizona, and a Fellow of both the American College of Cardiology and the American College of Surgeons. |
