## Schrodinger's equation (explanation to non physicist)For a report I'm writing on Quantum Computing, I'm interested in understanding a little about this famous equation. I'm an undergraduate student of math, so I can bear some formalism in the explanation. However I'm not so stupid to think I can understand this landmark without some years of physics. I'll just be happy to be able to read the equation and recognize it in its various forms.To be more precise, here are my questions.Hyperphysics tell me that Shrodinger's equation "is a wave equation in terms of the wavefunction".1. Where is the wave equation in the most general form of the equation?$\mathrm{i}\hslash \frac{\mathrm{\partial }}{\mathrm{\partial }t}\mathrm{\Psi }=H\mathrm{\Psi }$I thought wave equation should be of the type$\frac{{\mathrm{\partial }}^{2}}{{\mathrm{\partial }}^{2}t}u={c}^{2}{\mathrm{\nabla }}^{2}u$It's the difference in order of of derivation that is bugging me.2. Can somebody show me the passages in a simple (or better general) case?3.I think this questions is the most difficult to answer to a newbie. What is the Hamiltonian of a state? How much, generally speaking, does the Hamiltonian have to do do with the energy of a state?4.What assumptions did Schrödinger make about the wave function of a state, to be able to write the equation? Or what are the important things I should note in a wave function that are basilar to proof the equation? With both questions I mean, what are the passages between de Broglie (yes there are these waves) and Schrödinger (the wave function is characterized by)?5.It's often said "The equation helps finds the form of the wave function" as often as "The equation helps us predict the evolution of a wave function" Which of the two? When one, when the other?

## Factor 2 in Heisenberg Uncertainty Principle: Which formula is correct?Some websites and textbooks refer to$\mathrm{\Delta }x\mathrm{\Delta }p\ge \frac{\hslash }{2}$as the correct formula for the uncertainty principle whereas other sources use the formula$\mathrm{\Delta }x\mathrm{\Delta }p\ge \hslash .$Question: Which one is correct and why?The latter is used in the textbook "Physics II for Dummies" (German edition) for several examples and the author also derives that formula so I assume that this is not a typing error.This is the mentioned derivation:$\mathrm{sin}\theta =\frac{\lambda }{\mathrm{\Delta }y}$assuming $\theta$ is small:$\mathrm{tan}\theta =\frac{\lambda }{\mathrm{\Delta }y}$de Broglie equation:$\lambda =\frac{h}{{p}_{x}}$$⇒\mathrm{tan}\theta \approx \frac{h}{{p}_{x}\cdot \mathrm{\Delta }y}$but also:$\mathrm{tan}\theta =\frac{\mathrm{\Delta }{p}_{y}}{{p}_{x}}$equalize $\mathrm{tan}\theta$:$\frac{h}{{p}_{x}\cdot \mathrm{\Delta }y}\approx \frac{\mathrm{\Delta }{p}_{y}}{{p}_{x}}$$⇒\frac{h}{\mathrm{\Delta }y}\approx \mathrm{\Delta }{p}_{y}⇒\mathrm{\Delta }{p}_{y}\mathrm{\Delta }y\approx h$$⇒\mathrm{\Delta }{p}_{y}\mathrm{\Delta }y\ge \frac{h}{2\pi }$$⇒\mathrm{\Delta }p\mathrm{\Delta }x\ge \frac{h}{2\pi }$

Even if you have not heard about de Broglie equation physics before, the list of the questions dealing with this subject will help you to learn more as you browse through the answers and combine calculations, analysis, and the various equations. The general concept relates to the wave properties of matter with the main focus on the electron. According to de Broglie, the particles can exhibit the properties of the waves as you work with the mass of the particle. Take one de Broglie equation example and see how the particles cooperate with each other and describe the outcome received.
