does anyone know?

Time plays the exact same role in (non-relativistic) quantum mechanics as it does in Newtonian mechanics.
It's just a dynamical variable.
no t hat, remember?Originally posted by chroot

I'm aware that time is not an observable, has no corresponding operator, and so on, of course. I just goofed up and forgot the definition of the phrase "dynamical variable."

How does a dynamical variable then differ from a generalized coordinate (or velocity, or whatever)? Is a generalized coordinate an example of a dynamical variable?A "dynamical variable" satisfies an equation of motion in classical mechanics

Perimeter for what?
Great, thanks for clearing that up. I won't louse it up again.Originally posted by Tom
Yes, generalized coordinates and generalized momenta together make up the set of dynamical variables.

The quantum mechanics of time is the study of how time behaves at a microscopic level, as described by quantum mechanics. It involves understanding the nature of time, its properties, and how it interacts with other fundamental forces and particles.
According to quantum mechanics, time is not a fundamental physical quantity, but rather emerges from the interactions between particles and fields. The flow of time is described as a continuous and irreversible process, where the future state of a system is determined by its current state and the laws of quantum mechanics.
Yes, quantum mechanics can explain time dilation, which is the phenomenon where time appears to pass slower for objects moving at high speeds or in strong gravitational fields. This is due to the relationship between time and space, as described by the theory of relativity.
Quantum mechanics challenges our traditional understanding of time as a linear and continuous concept. It suggests that time may be non-linear, with the potential for multiple timelines or parallel universes to exist. Additionally, the concept of quantum entanglement suggests that events in the past, present, and future may be connected, blurring our perception of time.
The quantum mechanics of time has significant implications for our understanding of the universe. It suggests that time may have a beginning and an end, and that the laws of physics may have been different in the early stages of the universe's formation. Additionally, it raises questions about the ultimate fate of the universe and the possibility of time travel.
