The Dirac Equation is a Special Case of the Maxwell-Cassano Equations

submitted by: cloudmichael
The Dirac Equation is a Special Case of the Maxwell-Cassano Equations For vector Phi of D The Klein-Gordon equation may be written (see reference (4)): Whenever Phi of D is a 2 to the M-dimensional vector, via a matrix differential operator factorization, it may be written (in the Dirac representation), as shown here: and, since these matrix operators are commutative: conformability of the matrices requires thatthese matrices are all 2×1 matrices; yielding: For symmetry...

CES 2014: Barobo robots teach children algebra

submitted by: nsf

At the Consumer Electronics Show, CES 14, Barobo, Inc. showed the NSF their robot that helps teach children algebra in a completely new way. By taking algebra off the page and into the physical world, Barobo aims to inspire a new generation of mathematicians.

Science Nation - Music and Creativity

submitted by: nsf
Georgia Tech's Parag Chordia believes music is a universal part of human culture, and his research shows music education can inspire greater interest in math, physics, and computer science. Chordia heads Georgia Tech's "Music Intelligence Group." With support from the National Science foundation, his goals are to program computers to understand music the way humans do naturally - anticipating what is coming next. He's also studying changes in the brains of professional musicians as they play...

The Standard Model Architecture and Interactions Part 2 The Fermion Interaction

submitted by: cloudmichael
The Standard Model Architecture and Interactions Part 2 © 2011 Claude Michael Cassano The Fermion Interaction: An interaction with entry ingredients A,B and exit ingredients C,D is denoted as you see, here: A+B → C+D which implies it's anti-equivalent. A fermion interaction is an interaction between first and second order objects, i.e.: between solitary S sub R matrices. The initial step in a fermion interaction...

The Standard Model Architecture and Interactions Part 1

submitted by: cloudmichael
The Standard Model Architecture and Interactions © 2011 Claude Michael Cassano Based on my 1984 linearization of the Klein-Gordon equations, potential functions generalizations of the electric and magnetic field strengths form a basis from which a compound model simply constructs the leptons; the simple differences between the quarks and leptons; how the quarks arose from the leptons; why there are these two types of fermions; and why there are precisely three generations for each...

A Particular Solutions Inhomogeneous 2nd Order ODE Formula

submitted by: cloudmichael
A Particular Solutions Formula For Inhomogeneous Second Order Linear Ordinary Differential Equations © 2011 Claude Michael Cassano Finding a particular solutions to a linear inhomogeneous ordinary differential equation has always been a process of determining homogeneous solutions, and then adding any particular solution of the inhomogeneous equation. The well-known methods of undetermined coefficients and variation of parameters have long been the standard in determining...

A Helmholtzian operator and electromagnetic-nuclear field

submitted by: cloudmichael
A Helmholtzian operator is a linear second order partial differential operator, typically in four independant variables; a generalization of the d'Alembertian operator where it's additional constant vanishes. When the time-independant version (in three independent (space) variables acting on a function or vector vanishes, the resulting equation is called the Helmholtz's equation. In four dimensions this equation is referred to as the Klein-Gordon equation (with imaginary constant) . The...
