Information may exist in discrete chunks. A sentence can either be a full sentence which makes sense or a partial one which doesn't. In logic a piece of information exists in discrete chunks called well formes formulas, anything not satisfying those laws is not valid information.
In a similar...

Just to clarify, when i said photon above, i meant a discrete quanta of energy whether it is in the field, or wherever it is, or whether it is confined to an atom in its localised state. I just dont know what to call a discrete quanta of light in between emission and interaction, when...
OK guys thanks for hearing me out. For the sake of discussion I will respond to the above posts.

"First, collapse of the wave function is not necessarily an actual physical process"
Lets take the converse process. An atom absorbs a photon and then it elevates an electron to a...
I am sure this sounds silly but..
Between being emitted and interacting, a photon gives us no information as to where it is in space. If we know both where a photon was emitted from and where it then interacted, we can say that it travelled in a straight line. But we actually dont know.
So in...
De Broglie Wavelength is λ = h / p.
So at rest, v=0, and p=mv, so p=0. This means that λ = h/p = h/0 so we run into a divide by 0 issue, or infinite wavelengths for objects at rest.
Is this line of reasoning flawed?
Or can we consider v=1 for rest masses?
Time Dilation is related to v. The...
Hi, thanks for that. I found the below explanation on another site but I am not sure if it is exactly correct?

It was a long time since I studied this but from the OPs wording
PREMISE1: Every city with more than 5 million inhabitants is a metropolis.
PREMISE2: ABC is a city with more than 5 million inhabitants.
CONCLUSION: There is some city that is a metropolis.
(Edit: Ok I understand, I think I...
I cant remember the exact syntax rules but I think you have to use contradiction to prove these. It will go like this:
1. Premise: ForAll x If x pop > 5mill then x is a metro
2. Premise: ThereExist y such that pop y > 5mill
3. ASSUME: Not Exists z such that z is a metro
4. From 3...
Thanks guys, the responses helped, and I did some more researching and found what I was looking for.
Basically, what I meant to ask for was the difference between the emission spectrum and the absorption spectrum, but I didnt know to frame the question in those terms.
If I understand this...
Hello,
I understand that an electron in an atom can:
1. Absorb any amount of energy from a photon and become excited
2. It may move to a higher energy orbit or remain in the current orbit
3. To move to a lower energy orbit, it must release excess energy so it is at the ground level of the...
