Hi Alex,

I'm not arguing the power of math. What I want to know is exactly how your visualize all of this working as it does (and I mean exactly - perhaps more exact than you are normally used to thinking about this issue).

>>>It turns out that in physics an abstract mathematical category (say, force or mass) can be very "tangible". Force is defined as a derivative of momentum F=dp/dt (just a rate of change of momentum), and mass - as inertial property of energy.>So, again math "dictates" what tangible objects can (or can not) exist in universe.
