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... |

This is a video about 'ASSIST', A Shrewd Sketch Interpretation and Simulation Tool. MIT aims to create a tool that allows an engineer to sketch a mechanical system as she would on paper, and then allows her to interact with the design as a mechanical system, for example by seeing a simulation of her drawing. It has built an early incarnation of such a tool, called ASSIST, which allows a user to sketch simple mechanical systems and see simulations of her drawings in a two-dimensional kinematic simulator. |

Yale University is a private university in New Haven, Connecticut. Founded in 1701 as the Collegiate School, Yale is the third-oldest institution of higher education in the United States and is a member of the Ivy League. Particularly well-known are its undergraduate school, Yale College, and the Yale Law School, each of which has produced a number of U.S. presidents and foreign heads of state. In 1861, the Graduate School of Arts and Sciences became the first U.S. school to award the Ph.D. degree. Also notable is the Yale School of Drama which has produced many prominent Hollywood and Broadway actors, as well as the art, forestry and environment, music, medical, management and architecture schools, each of which is often cited as among the finest in its field. |

Abstract |
A non-Newtonian fluid is a fluid in which the viscosity changes with the applied strain rate. As a result, non-Newtonian fluids may not have a well-defined viscosity.
Although the concept of viscosity is commonly used to characterize a material, it can be inadequate to describe the mechanical behavior of a substance, particularly non-Newtonian fluids. They are best studied through several other rheological properties which relate the relations between the stress and strain tensors under many different flow conditions, such as oscillatory shear, or extensional flow which are measured using different devices or rheometers. The rheological properties are better studied using tensor-valued constitutive equations, which are common in the field of continuum mechanics.
An inexpensive, non-toxic sample of a non-Newtonian fluid sometimes known as oobleck can be made very easily by adding corn starch (cornflour) to a cup of water. Add the starch in small portions and stir it in slowly. When the suspension nears the critical concentration - becoming like single cream (light cream) in consistency - the so called "shear thickening" property of this non-Newtonian fluid becomes apparent. The application of force - f... |

Abstract |
|
Terence Chi-Shen Tao (陶哲軒) (born 17 July 1975, Adelaide, South Australia) is an Australian mathematician working primarily on harmonic analysis, partial differential equations, combinatorics, analytic number theory and representation theory.
A child prodigy, Tao is currently a professor of mathematics at UCLA. He was promoted to a full professor at age 24. In August 2006, he was awarded the Fields Medal. Just one month later, in September 2006, he was awarded a MacArthur Fellowship. He was elected a Fellow of the Royal Society on 18 May 2007.
Tao exhibited extraordinary mathematical abilities from an early age, attending university level mathematics courses at the age of nine. He is one of only two children in the history of the Johns Hopkins' Study of Exceptional Talent program to have achieved a score of 700 or greater on the SAT math section while just 8 years old (he scored a 760). In 1986, 1987, and 1988, Tao was the youngest participant to date in the International Mathematical Olympiad, first competing at the age of ten, winning a bronze, silver, and gold medal respectively. He won the gold medal when he just turned thirteen and remains the youngest gold medallis... |

He received the Salem Prize in 2000, the Bôcher Prize in 2002, and the Clay Research Award in 2003, for his contributions to analysis including work on the Kakeya conjecture and wave maps. In 2005 he received the American Mathematical Society's Levi L. Conant Prize with Allen Knutson, and in 2006 he was awarded the SASTRA Ramanujan Prize.
In 2004, Ben Green and Tao released a preprint proving what is now known as the Green-Tao theorem. This theorem states that there are arbitrarily long arithmetic progressions of prime numbers. The New York Times described it this way:[9][10]
“ In 2004, Dr. Tao, along with Ben Green, a mathematician now at the University of Cambridge in England, solved a problem related to the Twin Prime Conjecture by looking at prime number progressions — series of numbers equally spaced. (For example, 3, 7 and 11 constitute a progression of prime numbers with a spacing of 4; the next number in the sequence, 15, is not prime.) Dr. Tao and Dr. Green proved that it is always possible to find, somewhere in the infinity of integers, a progression of prime numbers of equal spacing and any length. ”
For this and other work, he was awarded the ... |

Abstract |
|
MATLAB is a numerical computing environment and programming language. Created by The MathWorks, MATLAB allows easy matrix manipulation, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs in other languages. Although it specializes in numerical computing, an optional toolbox interfaces with the Maple symbolic engine, allowing it to be part of a full computer algebra system.
Short for "matrix laboratory", MATLAB was invented in the late 1970s by Cleve Moler, then chairman of the computer science department at the University of New Mexico. He designed it to give his students access to LINPACK and EISPACK without having to learn Fortran. It soon spread to other universities and found a strong audience within the applied mathematics community. Jack Little, an engineer, was exposed to it during a visit Moler made to Stanford University in 1983. Recognizing its commercial potential, he joined with Moler and Steve Bangert. They rewrote MATLAB in C and founded The MathWorks in 1984 to continue its development. These rewritten libraries were known as JACKPAC.
MATLAB was first adopted by control design engineers, Lit... |

Abstract |
This is an example of the use of the Manipulate function in Mathematica 6 to animate a 3D plot. The function is sin(mx) x^p y + b where m, b, and p are being manipulated.
Mathematica is a general computing environment, organizing many algorithmic, visualization, and user interface capabilities within a document-like user interface paradigm. It was originally conceived by Stephen Wolfram, developed by a team of mathematicians and programmers that he assembled and led, and it is sold by his company Wolfram Research of Champaign, Illinois.
Since version 1.0 in 1988, Mathematica has steadily expanded into more and more general computational capabilities. Besides addressing nearly every field of mathematics, it provides cross-platform support for a wide range of tasks such as giving computationally interactive presentations, a multifaceted language for data integration, graphics editing, and symbolic user interface construction. An organized index of its functionality can be found here.
Many major educational and research organizations have Mathematica site licenses, and individual licenses are also sold. With Mathematica 6, a free interactive player is provided for running M... |

More clips from the Interview @ http://www.bbc.co.uk/sn/tvradio/progr...
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... |
