well I am having this problem while trying to write delta symbol in the question box. I have tries using two $ signs and delta between them. but nothing happened. Please help.
In physics, particularly in quantum physics, a system observable is a measurable operator, or gauge, where the property of the system state can be determined by some sequence of physical operations. For example, these operations might involve submitting the system to various electromagnetic fields and eventually reading a value off some gauge. In systems governed by classical mechanics, any experimentally observable value can be shown to be given by a real-valued function on the set of all possible system states.
Physically meaningful observables must also satisfy transformation la...
The framework of quantum mechanics requires a careful definition of measurement. The issue of measurement lies at the heart of the problem of the interpretation of quantum mechanics, for which there is currently no consensus.
Measurement from a practical point of view
Measurement is viewed in different ways in the many interpretations of quantum mechanics; however, despite the considerable philosophical differences, they almost universally agree on the practical question of what results from a routine quantum-physics laboratory measurement. To describe this, a simple framework to use i...

What applies to Gödel,1 may also apply to two Schrödinger tags: schrodinger-equation and non-linear-schrodinger. The third one, schroedingers-cat, being "right" already. So, whatever you may think of the umlaut, as it is now, it is being used inconsistently.
This would be a good use case for a t...

Apparently, it's Gauss's law, not (the) Gauss Law. I'm relying on Wikipedia here (and elsewhere), which sticks adamantly to the former. Please correct me in a comment if I'm wrong.
I think that to be consistent with all other such tags, e.g., coulombs-law, greens-functions, machs-principle, ferm...
