Did I do this right? An exercise in a book where my answer came out opposite from the author's. "camoo.freeshell.org/22.9.pdf"[/URL]

Thanks for checking.olgranpappy said:you are right. he has a sign error.
The Heisenberg picture is one of two commonly used formulations in quantum mechanics, the other being the Schrödinger picture. In the Heisenberg picture, the operators representing physical observables evolve in time, while the state vectors remain constant. This is in contrast to the Schrödinger picture, where the state vectors evolve in time and the operators remain constant.
The Heisenberg picture is significant because it provides a way to analyze the time evolution of quantum mechanical systems. It also allows for a more intuitive understanding of the concept of observables and how they relate to physical measurements.
In the Heisenberg picture, the operators representing observables evolve in time, while the state vectors remain constant. In the Schrödinger picture, it is the state vectors that evolve in time while the operators remain constant. This leads to different mathematical formulations and interpretations of quantum mechanics.
The Heisenberg uncertainty principle is a fundamental principle in quantum mechanics that states that it is impossible to simultaneously know the exact position and momentum of a particle. This means that the more accurately we know the position of a particle, the less accurately we can know its momentum, and vice versa.
The Heisenberg picture provides a way to visualize and understand the uncertainty principle. In this picture, the observables are represented by operators that evolve in time. This means that the uncertainty in the measurement of an observable at a particular time is related to the evolution of the operator representing that observable. The Heisenberg picture also allows for the calculation of the time evolution of uncertainty in a system.
