I'm pretty sure a proton's location does not have much quantum uncertainty but an up quark does. So qm uncertainty begins around 10^-15m and is full blown at 10^-18m
If my numbers are wrong please let me know.
My understanding of how one fermion changes the energy of another is something like: fermion x approaches fermion y and x emits bosons which are absorbed by y. But why does one billiard ball transfer a lot of its energy to another billiard ball on contact? Say billiard ball x approaches...
When a fermion x approaches another fermion y does x send out bosons to y which tell it to get out of the way? In short, how does y know to get out of the way of x?
Yea, I guess those toys of molecules are a bit of a waste of time. I certainly never bothered with them back when I taught myself chem.
I guess what I want to know is what does it mean to model motion.
I'm trying to come up with a good definition for model:
X is modeled means x exists at time 1 and point 1 and has direction y, then it will exist at time 2 and point 2.
Of course there are different types of modeling, for example, sometimes particles decay into other particles.
Let me...
Well, I'm more worried about who translated it from prose into notation. For example, in the 1500s math books were almost entirely written in prose. This began to change slowly I'm pretty sure between circa 1575 and 1625.
I know that this was done in the late 1500s and early 1600s and even al khwarizmi الخوارمي
in the 9th century did a lot to formalize math. I'm pretty sure fibonacci (not his real name) did not write his famous book using notation. I know Descartes did a lot to formalize math but the other...
See, that's what I thought. If you can't know the properties of an object then how do they know that their movements are random?
At the same time, the structure that gives rise to the galaxies supposedly is determined by the UP. And the distribution of the galaxies throughout the universe is...
I have a real hard time believing that. If the momentum cannot even be defined at the quantum level then how do you know it's deterministic? Plus in the text Susskind clearly says that atomic movements are random.
Also, to other members, I didn't get an answer regarding whether subatomic...
In the Cosmic Landscape, Susskind writes:
My question is if subatomic movements are random then does the conservation of momentum law break down at the quantum level? My hunch is yes. The conservation laws only apply at the classical level. Some people say that Noether's Theorem proves...
So what you seem to be saying is that there is not a general name that physicists give to that thing that causes motion. I thought it was energy. But you seem to be saying that energy is an abstract property particles have that can be used to predict other properties that the particle will...
In the double slit experiment wavicles go through one slit of the other in roughly a 50/50 ratio. How does this not violate conservation of momentum? They would need momentum to push them to the right or the left.
