Unlike

Dirac and Majorana fermions, members of the Weyl class--named after German mathematician and physicist Hermann Weyl--are massless.

The diffusive nature of this equation is problematic but vanishes in the relativistic limit of the

Dirac equation.

The calculations were carried out using the COSMA supercomputer at Durham University, which is part of the UK-wide

DiRAC super-computing framework.

One side of the board - called the

Dirac Sea - is yin, the other yan.

Used in combination with the

DIRAC 6 room acoustics software, the new Echo Speech Source Type 4720 enables users to perform speech intelligibility measurements, which meet standards IEC 60268-16 and ISO 3382-3 (open plan offices).

Our calculations required about 3 million CPU (central processing unit) hours alone; processing power only accessible to us through the

DiRAC project.

New York (AirGuideBusiness - Business & Industry News) Wed, Mar 5, 2014 - An international research team has identified a sodium bismuthate compound that they call three-dimensional topological

Dirac semi-metal, which could have applications in semiconductors and data storage, possibly outperforming the characteristics of graphene.

Monopoles" had been predicted by physicist Paul

Dirac in 1931 - but remained elusive till now.

After preliminaries, they cover self-adjoint and skew-self-adjoint

Dirac systems: rectangular matrix potentials, linear system auxiliary to the nonlinear optics equation, discrete systems, integrable nonlinear equations, generalized Backlund-Darboux transformation (GBDT) theorems and explicit solutions of nonlinear equations, some further results on inverse problems and GBDT, and sliding inverse problems for radial

Dirac and Schrodinger equations.

Coincidentally, this same school was previously attended by Paul

Dirac, the scientist often described as the father of quantum mechanics, who also became a Nobel Prize winning physicist.

The celebrated contribution of

Dirac [18] ensures that this is always the case.

Such oversights include: the Double Slit Experiment never has been interpreted accurately, as the methods used by physicists to conduct that experiment failed to hold the variable momentum constant; the

Dirac equation attempted to unify relativity and quantum mechanics 80 years ago, but never has been interpreted correctly by physicists as the key to the unification of physics; the pictorial claims of matter and antimatter are illogical, given that oppositely charged particles should be attracted to each other rather than repelled; and a discussion of the real problem with siring theory.
