So im doing some reading in Zettilis Quantum mechanics book and came across this passage Now the thing im left dumbfounded on is why it can be considered normalizable? I tried finding some explanation in the book but that didnt yield anything other than some vague verbal argument for it. Now i t...

I know I am asking out of my limits, but i felt relaxed thinking about this. Now I read somewhere about quantum fluctuations (that energy can be generated in randomly at two positions where total sum of the energy is zero. So i researched about it a little and found that they are completely proba...

Suppose we a have an anode and cathode and between them there is vacuum. If we applies a sufficiently high voltage between them, can we have small electric current?

Wikipedia says The fictitious force is due to an object's inertia when the reference frame does not move inertially, and thus begins to accelerate relative to the free object. The fictitious force thus does not arise from any physical interaction between two objects, such as electromagnetism or ...
