Dirac Equation in The Algebra of Physical Space

Dirac Equation In The Algebra Of Physical Space

The Dirac equation, as the relativistic equation that describes spin 1/2 particles in quantum mechanics can be written in terms of the Algebra of physical space (APS), which is a case of a Clifford algebra or geometric algebra that is based in the use of paravectors.

The Dirac equation in APS, including the electromagnetic interaction, reads

Another form of the Dirac equation in terms of the Space time algebra was given earlier by David Hestenes.

In general, the Dirac equation in the formalism of geometric algebra has the advantage of providing a direct geometric interpretation.

Famous quotes containing the words equation, algebra, physical and/or space:

    Jail sentences have many functions, but one is surely to send a message about what our society abhors and what it values. This week, the equation was twofold: female infidelity twice as bad as male abuse, the life of a woman half as valuable as that of a man. The killing of the woman taken in adultery has a long history and survives today in many cultures. One of those is our own.
    Anna Quindlen (b. 1952)

    Poetry has become the higher algebra of metaphors.
    José Ortega Y Gasset (1883–1955)

    When one walks, one is brought into touch first of all with the essential relations between one’s physical powers and the character of the country; one is compelled to see it as its natives do. Then every man one meets is an individual. One is no longer regarded by the whole population as an unapproachable and uninteresting animal to be cheated and robbed.
    Aleister Crowley (1875–1947)

    I would have broke mine eye-strings, cracked them, but
    To look upon him, till the diminution
    Of space had pointed him sharp as my needle;
    Nay, followed him till he had melted from
    The smallness of a gnat to air, and then
    Have turned mine eye and wept.
    William Shakespeare (1564–1616)
