  1. Re:newtonian prediction on Gravitation Anomaly Measured · · Score: 1

    The trajectory of a particle under the influence of a gravitational field is independent of its mass; that was Galileo's observation. So yes, massless particles are deflected by gravity, by the same amount as massive particles. The deflection depends only on the impact parameter and initial speed.

    I was under the impression that the force of gravity would be 0 for a massless particle.
    According to newtons laws of gravitation

    F = GMm/R^2 (where G is gravitational constant, M and m are the masses of particles and R is the distance).

    If force is 0, then I infered that acceleration would be 0 and trajectory would be a straight line.

    Assuming a test particle of negligible (could be zero, but doesn't have to be) mass, with initial speed c. You can see the calculation outlined in, for instance, Ohanian and Ruffini (IIRC).

    Was it assumed for the newtonian prediction that photons have a slightly positive mass? Because I still calculate that a 0 mass particle results in a force of gravity = 0 using Newtonian gravitation.

    Did Newton assume that 0 mass particles require no energy to accelerate (because they have 0 mass), and would simply accelerate in gravity at the same rate as massive particles because other massive particles all happened to accelerate equally regardless of mass.

    If that is the case, then my understanding was incomplete and I was too quick to conclude that newtonian model predicts 0 deflection of massless particles in a gravity field, and I will withdraw my statement because I would be wrong to take that position.

    For nearly 40 years, we have told blacks and other minorities that, because their ancestors were slaves, and their parents were discriminated against under the law, they not only have an excuse for not succeeding, they are expected to not succeed,

I believe what we are saying is, because your parents have been ripped off, and your grandparents were treated as animals, you are going to be at a competetive disadvantage with others, on average, who have not been wronged in such ways, and have inherited some cash to go along with the privilege.

    if it is racist to admit being a benefactor of previous crimes commited against people of a particular race.

    - but, these same white liberals have also modified the language so that it is now racist to suggest that any color humans are just as good as any other other color humans, because this is the basis for removing all race-based preference systems.

    You are right. That is what the definition of racist is.

    But I'm not sure what your point is.

    Administering these race-based preference systems is a lucrative business, which feeds upon emotion to keep thousands of guilt-ridden people employed.

    are you saying that affirmative action should be abolished because administration costs hurts corporate america?

    Or are you saying that people who work in administering affirmative action programs are guilt ridden, and thus to impose such a job on anyone is inhumane?

    Many things that are attributed to current discrimination by these people are not really - for example, there are fewer minorities and women in top-level management because they haven't been at it as long.

    ummm... because women and blacks just suddenly sprang into existence 40 years ago...?

    I follow.

    When top management requires 20 years of experience, it takes a while for an increased presence of minorities in the lower eschelons to move their way up the latter, unless they're pushed upward, beyond their current merit, to satisfy the appearance of discrimination. And such fast-tracked individuals may lack skills that time would have given them, so they feel pressured to do what they can't do, and the detractors amongst their peers see it as "proof" of the premise that minorities "aren't good enough".

    Umm.... black people and women have actually been around longer than 20 years.

    I've seen many more examples of undeserving white people in top management. Do you have any statistics to show that women and minorities are more likely to fail when put into top management positions than white men?

    But the bottom line is. America is built on the backs of slaves.

    It doesn't matter if affirmative action is difficult to implement for white people.

    To accept that argument would be to say that the defendant in a civil proceedings be excused from paying damages because it costs money.

    Historically, white owners left their wealth in lands and properties to their white kids. They obtained their wealth with the help of involuntary slaves, and stole the land from the first nations peoples, who they commited genocide against. That wealth should have gone in part to those slaves, and natives, to be left to todays generation of black americans and native-americans.

It is absolutely impossible to secure every single mile of road, every train track, every building, every hospital, every boat, every mail parcel, every nook and crany inside or outside of America. And as long as Al Qaeda or islamic fundamentalists still exist, there will be unsecured targets to attack.

    Democracies go to war because of what is right and good. Not in order to earn cash prizes. It is morally offensive.

    And certain multi-national corporations with very close ties to the Bush administration benefited splendidly from the war in Iraq. It is a conflict of interest. It smells like corruption.
