Why, when you are doing a sterling job of showing your ignorance.... You never did define how the area vector is defined for an irregular area.... particularly one that lies on a curved surface, for example. mass as a vector! What does the DIRECTION of the mass vector represent? $10 fnlf V unir gb cnl sbe gur nafjre....! -- Sacred keeper of the Hollow Sphere, and the space within the Coffee Boy singularity.

The freshman physics formulae [all of which I have derived in more general situations] that you use are only true in one dimensional cases. Your way of generalizing to higher dimensions is wrong, but not nearly as wrong as concluding all physicists are stupid because you never went past introductory physics. I thought Asians were supposed to be good at mathematical based sciences?

Again, let's check this equation pressure = force / area. Force is a 3D vector and pressure is a scalar, therefore area is a 3D vector. <area> = <force> / pressure

Stop generalizing from equations that are true in only one dimension. |
