How do you change the math of F = ma?

Yeah, that was basically my question: relative to what observer?

And how do you think inertial navigation systems work?

"GR is non-Machian" Hmm. In layman's terms, does the mass in the large universe cause the local centrifugal force (according to GE)?

Let's say I choose the earth as the frame of reference. I.e. the earth is motionless with respect to that frame. Why is it experiencing centrifugal force?

If the universe is rotating around the car why is the car experiencing centrifugal forces?

If linear motion is relative, how come that rotary motion is absolute? And if it is not absolute what is is relative to?

How about in reality?

I am proposing a new theorem of computability theory: THEOREM 1: There are numbers k and s and a program A(n,m) satisfying the following conditions. 1. If A(n,m)↓, then C_n(m)↑. 2. For all n, C_k(n) = A(n,n) and C_s(n) = C_k(s). 3. A(k,s)↓ and for all n, A(s,n)↑. Here C_n(∙) is a program with...

Does chaos amplify inherent quantum level randomness/uncertainty to macroscopic level?

Energy distribution is THE problem.

OK, so let me put it this way. Suppose that we put gas molecules in a container. We start with all the molecules on the left having high kinetic energy, and all the molecules on the right having low kinetic energy. We run the simulation, and the kinetic energy will even out. Then we rerun the...

I do not like the word "probably."

"If the simulation is reversed, the molecules will retrace their paths back to the initial conditions, temporarily decreasing entropy. However, if the simulation continues to run, the molecules will once again disperse, increasing entropy." Hmm ...

How do these simulations work? The molecules are points or spheres? They all have the same mass, and you randomly select position and velocity for each? And they will converge to higher entropy? Just flip the signs of the velocities, and entropy will decrease. "Backward" velocities are just as...
