History of Classical Mechanics - Present

Present

By the end of the 20th century, classical mechanics in physics was no longer an independent theory. Along with classical electromagnetism, it has become imbedded in relativistic quantum mechanics or quantum field theory. It defines the non-relativistic, non-quantum mechanical limit for massive particles.

Classical mechanics has also been a source of inspiration for mathematicians. The realization that the phase space in classical mechanics admits a natural description as a symplectic manifold (indeed a cotangent bundle in most cases of physical interest), and symplectic topology, which can be thought of as the study of global issues of Hamiltonian mechanics, has been a fertile area of mathematics research since the 1980s.

Famous quotes containing the word present:

    You know, I often thought that the gangster and the artist are the same in the eyes of the masses. They’re admired and hero-worshipped but there is always present underlying desire to see them destroyed at the peak of their glory.
    Stanley Kubrick (b. 1928)

    The present is never our end. The past and present are our means; the future alone is our end. So we never live, but hope to live; and, as we are always preparing to be happy, it is inevitable that we should never be so.
    Blaise Pascal (1623–1662)

    There is always a present and extant life, be it better or worse, which all combine to uphold.
    Henry David Thoreau (1817–1862)
