Discussion Overview

The discussion centers on the core equations of quantum mechanics (QM) and their potential contradictions with the equations of relativity. Participants explore various equations that govern QM and express curiosity about the mathematical inconsistencies between these frameworks.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the main equations governing quantum mechanics and expresses a desire to understand the contradictions with relativity.
  • Another participant cites the Schrödinger time-dependent equation as a fundamental equation in QM that defines the time-evolution of a quantum state.
  • It is mentioned that there are multiple equations depending on different formulations of QM and different pictures within those formulations.
  • A participant highlights the Schrödinger equation as key in non-relativistic quantum mechanics and introduces the Dirac equation as the first relativistic QM wave equation, noting its implications for particle creation and quantum field theory (QFT).
  • Participants engage in correcting formatting issues related to the presentation of equations.

Areas of Agreement / Disagreement

Participants present various equations and formulations of quantum mechanics, but there is no consensus on the specific contradictions with relativity or how these equations interact. The discussion remains open-ended with multiple viewpoints expressed.

Contextual Notes

Some assumptions about the definitions and interpretations of the equations are not fully explored, and the discussion does not resolve the complexities of the relationships between quantum mechanics and relativity.

firstly, I am deeply astounded at my typing job in the title..

what are the main equations governing qm, I am sure that atleast a few must exist, though i fail to turn them up in any place i look. To aim you more toward what i seek in particular should I be plesently surprised with a plethora of potentially intriguing equations, I wish to be pointed toward the contradictions in the equations mathmatically to those governed by relativity. Do not worry about my level of understanding in math due to my lack of knowing in the field of qm, but i have been focusing for a long while on relativity, and by now realized that i have neglected it opposition whilst i can nearly recite the list of (Eeinstein) field equations from memory.



-can this question be that foolish...? surely someone will comment

Schrödinger time-dependent equation which governs the time-evolution of a quantum state (or rather defines what a quantum state can be).

H\left|\psi\left(t\right)\right\rangle = i\hbar\frac{\partial}{\partial t}\left|\psi\left(t\right)\right\rangle

We've also got other equations if we adopt different formulations of QM and within one formulation different pictures.

The key equation in NR QM is the Schrödinger equation:
\frac{-\hbar^2\nabla^2}{2m}\Psi+V\Psi=i\hbar\frac{\partial\Psi}<br /> {\partial t}.
This is based on T=p^2/2m.
The first relativistic QM wave equation was the Dirac equation:
[{\bf \alpha\cdot p}+\beta m]\Psi=i\hbar<br /> \frac{partial\Psi}{\partial t}.
Here p=i\hbat\nabla.
The problem (gain) arose that the Dirac Eq. led to the creation of more particles and on to QFT, the only quantum theory that is compatible with SR.

Edit: correcting TEX formatting.

thanks meir also, taking me a bit to piece togther the tex, i don't use it a ton but it gives me an ida of what to look for.
