Order parameter, correlation function and length

AI Thread Summary
The discussion revolves around the confusion regarding the relationship between various physics concepts, particularly Newton's second law and the reasons for gravitational attraction. Newton's second law states that the force acting on an object is equal to its mass times its acceleration, which explains why objects fall down due to the force of gravity acting on them. The question of why things fall down instead of up is tied to the fundamental principles of gravity, which is an attractive force that pulls objects toward the Earth. The conversation emphasizes the importance of understanding established physical principles through experimentation and observation. Overall, grasping these concepts is crucial for a deeper understanding of physics.

Hello people,

I don't understand the relation between those concepts, I tried to read what's written in wikipedia about them but no use.

Can someone please elaborate more about the relation between them in some intuitive manner?

Thank you :)

Come on physicists! show me your powers :)! Please, I really need to understand this :'(.
 
Very well, I have an easier question though, since there is not a single comment!

Here is the question...

What's Newton's second law? and why do things fall down not up?

Think hard guys! it's not that easy :P
 
why don't things fall up? if you will answer on it you will answer on your second question...

You should start to believe in any general physical principles which were established by experimental way (or theoretical if it was proof by experiments or predicted of course)... and if you doubt one's own eyes you should sleep more...Denis

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Highway: Deriving speed from Doppler shift'

I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
