    History of Hinduism in Pakistan

    See Also: History of Hinduism, Indus Valley Civilization, Vedic civilization

    Hinduism, once the main religion in Pakistan, has endured many conquests and invasions, different rulers, and ultimately political separation from the Hindu-majority India.
    [edit]

    Ancient Ages

    What is today Pakistan is where the ancient Mehrgarh and Indus Valley Civilization thrived. Various archaeological finds such as what appears to be like a "Pasupati" image that was found on the seals of the people of Mohenjo-daro, in Sindh, point to early influences that may have shaped Hinduism. The Elamo-Dravidian arrived from Eastern Iran and settled in Indus valley. According to a widely prevalent theory, a group of people known as Aryans migrated from regions like Iran or Eastern Europe, crossed the river Sindhu, and mingled with the Dravidians and indigenous people. The religious beliefs and folklore of the Indus valley people have become a major part of the Hindu faith that evolved in this part of the South Asia.

    The Sindh kingdom and its rulers play an important role in the Indian epic story of the Mahabharata. In addition, there is the legend that the Pakistani city of Lahore was first founded by Lava, the son of Rama of the Ramayana. The Gandhara kingdom of the Northwest, and the legendary Gandhara peoples are also a major part of Hindu literature such as the Ramayana and the Mahabharata.
    [edit]

    Buddhism

    During the reign of Ashoka, Buddhism grew and thrived in the area, especially under the later rule of Kanishka, king of the Kushan Empire. With the ascent of the Gupta Dynasty, many Buddhists were returned to the Hindu fold in India, as Hindus adopted many of the teachings of the Buddha such as non-violence to all life, vegetarianism and proper treatment of fellow men. A substantial Buddhist community that rivalled the Hindus would remain in Pakistan until the Islamic conquests.

    Some scholars believe that Vedic Hinduism was never very strong in Pakistan, but records left by scholars like Alberuni, do not provide any such hint. In addition, a large Buddhist population remained in the Punjab and Sindh as Arab invaders attest to having encountered many 'Buddh' statues of gold throughout the region. Due to the nature of the region as a borderland on the edge of South Asia many people more open and receptive to radically different ideologies like Islam and other Semitic faiths.
    [edit]

    Under Islamic and British Rule

    People in this region were exposed to Islamic teachings when the country came under the control of Muslim rulers. Though many Hindus voluntarily became Muslims, many Hindus also believe that a large number were forced to become Muslims. Alberuni states in his book, that Hindus who were forced to become Muslims, were not reaccepted into their community, when they escaped to places like Varanasi. He in fact laments, that due to Islamic conquests, many great Hindu scholars left this region. In over one thousand years of Muslim rule in the Punjab and Sindh, the population of Muslims outpaced the growth of Hinduism and Buddhism virtually disappeared, although relationships between people were peaceful and much more friendly than in modern times. Many Muslims still retained many of the traditions and cultural influences of the times when some were a part of the original Hindu population. It was not uncommon at all to hear a Muslim greet a Hindu or another Muslim with the traditional northern Indian greeting of Rama, Rama.

    In August 1947, at the end of British Raj, the population percentage of Hindus in what is today Pakistan was perhaps as high as 30-35%, but would drop to its current total of less than 2 % in the years since partition.
    [edit]

    PRL 96, 154502 (2006)
    To explain our observations, we propose the following
    model. As liquid evaporates at the bottom surface of the
    droplet, the pressure that levitates the droplet pushes out
    the vapor laterally. We propose that the ratchet surface
    partially rectifies this vapor flow, which exerts a net viscous
    force on the droplet. In the following, we calculate the
    magnitude of this force by estimating the pressure gradient
    underneath the droplet that drives the vapor flow. It is
    important to note that evaporation and vapor flow are
    powered by heat from the substrate. The droplets are thus
    essentially heat engines.
    A droplet placed on a ratchet [see Fig. 3(a)] tends to
    curve concavely around the tops of the ridges (point A)
    while assuming a convex shape elsewhere. This variation
    in droplet curvature can be used to estimate the variation of
    the dynamic pressure along the vapor layer as explained in
    the following. The local difference between the droplet's
    internal pressure pi (assumed constant along the bottom
    surface) and the pressure in the vapor film is given approximately
    by the Laplace pressure p =R, where R
    is the local radius of the curvature (assuming no curvature
    parallel to the ratchet ridges) [3]. A concave surface shape
    (near point A) corresponds to a curvature RA
    pi, while the convex curvature at points B1 and B2 implies
    RB > 0 and pB pB. We therefore
    expect net vapor flow from point A to points B1 and B2.
    Flow from A to B2 is expected to create a viscous force in
    forward direction, which we estimate below. In contrast,
    vapor flowing from A ''backward'' can escape sideways
    along the wide ratchet grooves [into and out of the page in
    Fig. 3(a)], because of the small flow resistance in this
    direction [18]. Therefore, net forces due to vapor flow
    between A and B1 should be relatively small.
    The force exerted by the vapor on the liquid between
    points A and B2 has two components. First, a forward shear
    force due to Poiseuille vapor flow caused by the pressure
    differential P pA pB. Using nonslip boundary
    conditions and a parallel-plate model.model, the horizontal component
    of this force is [19]
    F 0:5AeffhjdP=dxj cos; (2)
    where Aeff is the total area over which this force contributes
    (depending on droplet size, multiple ratchet periods are
    involved), h is the thickness of the vapor layer in this area,
    and is defined in Fig. 3(b). Second, if the droplet glides
    with x relative to the substrate, there is a viscous drag
    force given by [19]
    x Aeff=hx; (3)

    Yes, that is true. But, that acceleration is the centripetal acceleration which iscaused by the motor of the centrifuge, not by any nonexistent "centrifugal force" (even if we accept the concept of force, which itself is nonexistent as I have stated in posts above).

    In what follows I adhere to the standard definition of "centrifugal" force as the non-inertial force, not as the normal reaction to centripetal force.

    The force of the motor gets propagated by Newton's 3rd law through the atomic interaction of the walls of the centrifuge and transferred to the fellow in contact with it. So the force experienced by the fellow in the chamber is the force due to the motor.

    The other way to look at it is that there is no motor, but there is an accelerated frame (where the motor is conceptually unimportant as it is outside your universe of the accelerated frame), and you follow an artificial recipe that says that you should just "plug in" (by rote) a force term (in this case "centrifugal force") equal to -mass*acceleration_of_the_frame. This recipe is convenient sometimes, but unnecessary as we can get the same result from ab-initio reasoning as in the previous paragraph.

    So what you are doing is assuming that the centrifuge is a different universe, where all physical phenomena are appended by this universal divine "centrifugal force". I dunno abt you, but that's too wierd for my taste.

    There is no such thing as centrifugal force. The very idea is completely bogus and unnecessary and so can be removed from all formalisms of accelerated frames without losing any of the physics, so it does not exist.

    It's ambiguities like this that proves that the whole concept of force is a pile of rubbish and can easily be done away with (okay, maybe not easily, but the formalisms in classical mechanics that get rid of forces are far more elegant and insightful than all this clunky Newtonian stuff, and).

    In case you think I'm being pedantic, I should point out that Hamiltonian, Lagrangian and canonical formalisms are significantly easier to implement computationally in systems where analytical solutins cannot be done (likechaotic systems or quantum systems with multiple nonlinear resonances) because of their logically algorithmic structure, so in the modern world of research, nobody implements all this "force" stuff into their computations.

    Erm, actually, capital case "G" is the universal gravitational constant ( 6.67300 × 10-11 m3 kg-1 s-2), and the only "unit" of acceleration is length per time squared. The acceleration due to gravity (at the poles and at a radial distance equal to the mean radius of the earth 6 378.1 kilometers) is denoted by small case "g" (~9,8 m.s^2 or 32 ft/s^2 for the Americans) and is not a good "unit" per se (because it's not really constant).

      Oh, and just FYI for everybody, there is no "acceleration", "pressure" or "force" directly experienced inside a centrifuge. What is experienced is a non-inertial pseudoforce which is the result of transforming to an accelerated frame.

    No builds of DemocracyPlayer for Mandriva. Can't install Fedora rpm on Mandriva 2005 because of unresolvable deps wrt libstdc++...


    Tried to compile from source (stable, not svn), but couldn't make heads-or-tails of the README (half-done).

    Anybody have any luck with non-Debian/Fedora Distros?
