Under his influence Dirac worked on some problems in statistical mechanics. |
|
The theory of QED developed by Paul Dirac, Richard Feynman and others fantastically explains a wealth of optical phenomena. |
|
Although it has been demonstrated to provide high quality in real time on a variety of platforms, Dirac is still in development. |
|
Developing Dirac as an open technology requires a different approach to the conventional way in which standard codecs are designed. |
|
This is an unusual feature in compression systems and allows software that uses Dirac to navigate much more easily through the bitstream. |
|
Dirac is designed to achieve good subjective compression performance by using a few tools guided by psychovisual criteria. |
|
The relative simplicity and clean architecture of the Dirac codec supports high performance. |
|
Reduced complexity makes Dirac easier to understand, easier to implement and easier to optimize for real-time performance. |
|
Back in 1928, Dirac had the temerity to take the second solution seriously, and today the beast is a tamed antiparticle known as a positron. |
|
Dirac uses a small number of core tools, chosen for subjective performance. |
|
This allows future implementations of Dirac more freedom and, therefore, more scope to improve performance. |
|
Therefore it is premature for Dirac to be a consumer proposition at the moment but that will come with time. |
|
When Dirac developed the general principles of quantum theory, this democratic equality between different points of view was maintained in the new dynamics that resulted. |
|
The second pillar of QED consists in the relativistic theory of the electron, with the Dirac equation in its centre. |
|
Although the quality metric used by Dirac is quite simple, it is surprisingly effective. |
|
Four years later Dirac's positron was also found in a cosmic ray shower and in 1933 Dirac was awarded the Nobel Prize in Physics for his extension of atomic theory. |
|
Of course, a modern state-of-the-art codec is, inevitably, quite complex, but we have tried to minimize this in Dirac. |
|
As an open technology, Dirac must be straightforward to understand and easy to use. |
|
As a young professor, you have already this year been awarded the prestigious Dirac Medal by the World Association of Theoretically Oriented Chemists. |
|
Among forty winners there are Russian and foreign researchers: Nobel laureate Ferid Murad, Fields medal winner Stanislav Smirnov, Dirac medal awardee Vladimir Zakharov and others. |
|
|
These problems were solved by the development of quantum mechanics in the 1920s by Heisenberg, Schrodinger, Dirac, and others. |
|
We can repeat the process to achieve higher levels of wavelet transform. The benefits of higher levels diminish with each level, so Dirac usually only uses a four-level wavelet transform. |
|
After his father died in 1936, it emerged that he had not given Dirac the essential £5, although he could have done so, having hoarded more than £7,500, some 15 times his annual salary. |
|
Taimanov gave a representation formula for minimal surfaces in 3-dimensional Lie groups in terms of spinors and Dirac operators. |
|
In this section, we shall derive an expression for the conductance of a bilayer graphene by solving the eigenvalue problem Dirac equation. |
|
The Dirac player is not quite apt for real time on lower-end machines. |
|
Particles such as electrons and protons, according to a hypothesis proposed by Enrico Fermi and P. A. M. Dirac, must have antisymmetric wave functions. |
|
Whilst conventional block transform codecs are approaching the end of their useful development cycle, Dirac is only at the beginning of its development. |
|
The Dirac development consists of two parts: a compression specification for the bitstream and decoder, and software for compression and decompression. |
|
In essence, in developing the Dirac codec, we have simply been trying to emulate the successful methodology used for the development of the Internet. |
|
There is already experimental support for Dirac in a number of media players, including Windows Media Player, and this support will continue to strengthen. |
|
Dirac is open technology, freely available to all, which suits the requirements of public service broadcasters and supports the use of digital technology by consumers. |
|
The topological charge of families of lattice gauge fields is defined fermionically via families index theory for the overlap Dirac operator. |
|
Among other discoveries, he formulated the Dirac equation which describes the behaviour of fermions and predicted the existence of antimatter. |
|
Paul Adrien Maurice Dirac was born at his parents' home in Bristol, England, on 8 August 1902, and grew up in the Bishopston area of the city. |
|
When Dirac found that he could not express what he wanted to say in French, he chose to remain silent. |
|
Dirac was famously not bothered by issues of interpretation in quantum theory. |
|
Dirac is regarded as the founder of quantum electrodynamics, being the first to use that term. |
|
A workaround known as renormalisation was developed, but Dirac never accepted this. |
|
From September 1970 to January 1971, Dirac was Visiting Professor at Florida State University in Tallahassee. |
|
|
He donated the royalties from this book to the university for the establishment of the Dirac Lecture Series. |
|
The Silver Dirac Medal for the Advancement of Theoretical Physics is awarded by the University of New South Wales to commemorate the lecture. |
|
Dirac Science Library at Florida State University, which Manci opened in December 1989, is named in his honour, and his papers are held there. |
|
The street on which the National High Magnetic Field Laboratory in Innovation Park of Tallahassee, Florida, is located is named Paul Dirac Drive. |
|
As well as in his home town of Bristol, there is also a road named after him in Didcot Oxfordshire, Dirac Way. |
|
In 1989 he was awarded the Dirac Medal and Prize of the British Institute of Physics. |
|
He was the first to use the unit impulse function now usually known as the Dirac delta function. |
|
In this paper the authors reconsider the Dirac brackets for fermionic coordinates in the context of quantum deformations of the superplane. |
|
Paul and Margit Dirac had two children together, both daughters, Mary Elizabeth and Florence Monica. |
|
Dirac was able to maintain his normal research productivity only because Manci was in charge of everything else. |
|
According to a story told in different versions, a friend or student visited Dirac, not knowing of his marriage. |
|
In 1971, at a conference meeting, Dirac expressed his views on the existence of God. |
|
Dirac did not commend himself to any definite view, but he described the possibilities for answering the question of God in a scientific manner. |
|
In 1984, Dirac died in Tallahassee, Florida, and was buried at Tallahassee's Roselawn Cemetery. |
|
Fowler sent Heisenberg's paper on to Dirac, who was on vacation in Bristol, asking him to look into this paper carefully. |
|
This was unusual at a time when secondary education in Britain was still dedicated largely to the classics, and something for which Dirac would later express his gratitude. |
|
Dirac established the most general theory of quantum mechanics and discovered the relativistic equation for the electron, which now bears his name. |
|
In 1931, Dirac proposed that the existence of a single magnetic monopole in the universe would suffice to explain the quantisation of electrical charge. |
|
Dirac was known among his colleagues for his precise and taciturn nature. |
|
Dirac himself wrote in his diary during his postgraduate years that he concentrated solely on his research, and stopped only on Sunday, when he took long strolls alone. |
|
|
For this work, published in 1926, Dirac received a PhD from Cambridge. |
|
The injection in all cases is small enough in mass and time, compared to the flow rates and to the residence times, to be considered as a Dirac pulse. |
|
This work led Dirac to predict the existence of the positron, the electron's antiparticle, which he interpreted in terms of what came to be called the Dirac sea. |
|
Dirac became a member of the Order of Merit in 1973, having previously turned down a knighthood as he did not want to be addressed by his first name. |
|
The opening of a light switchable band gap and the shifting of the Dirac point in graphene through non-covalent doping with photochromic molecules. |
|
Dirac's childhood home in Bristol is commemorated with a blue plaque and the nearby Dirac Road is named in recognition of his links with the city. |
|
On 13 November 1995 a commemorative marker, made from Burlington green slate and inscribed with the Dirac equation, was unveiled in Westminster Abbey. |
