What is quantum spin? Is it a literal spin? How does it generate magnetic fields?

Most of these guys just look like regular fucking college age boys. Most of them aren't particularly attractive, but I wouldn't call any of them downright ugly. You need to curb your sociopathy.

>"It is an eternal cycle in which matter moves, a cycle that certainly only completes its orbit in periods of time for which our terrestrial year is no adequate measure, a cycle in which the time of highest development, the time of organic life and still more that of the life of being conscious of nature and of themselves, is just as narrowly restricted as the space in which life and self-consciousness come into operation. A cycle in which every finite mode of existence of matter, whether it be sun or nebular vapour, single animal or genus of animals, chemical combination or dissociation, is equally transient, and wherein nothing is eternal but eternally changing, eternally moving matter and the laws according to which it moves and changes.
Christopher Langan tier nonsense. Ken Wheeler tier rambling bull.

because we express ourselves differently
also, check my sevens

lmao whats so advanced about them a tensor is literally just a matrix that transforms like
[eqn]\sigma'=Q\sigma Q^{T}[/eqn]

lmao whats so advanced about them a tensor is literally just a square matrix of numbers that transforms like

something something conservative forces and state functions

Forces can be conservative (based) or nonconservative. This relates to how energy is conserved in a system involving them. Gravity and electric fields are conservative, for example. F is a conservative field if there is a scalar potential function of space such that [math]\mathbf{F}=-\nabla V[/math]. The implication is that conservative fields are path independent; the work performed only depends on the endpoints of the path and not on what happens along the way. In other words,
[eqn]\int_{P}\mathbf{F}\cdot d\mathbf{r}=V(\mathbf{r}_{2})-V(\mathbf{r}_1)[/eqn]
Equivalently, conservative fields do not perform any work when the object moved through a closed path.
[eqn]\int_C\mathbf{F}\cdot d\mathbf{r}=\mathbf{0}[/eqn]
when C is a closed loop.

Things like friction and magnetic fields are not conservative. Imagine friction: obviously if you take a more circuitous path from A to B, there will be more friction and more work done by friction. Not path independent. The curled magnetic field that forms around a wire is also not path independent, it can be "clockwise" or "counterclockwise." When you start talking about heat, you have to realize that "heat" is actually just the transfer of the kinetic energy of 10^23's of tiny little particles. You can't represent heat with a function of state, meaning you cannot exactly related it to other properties like you can with pressure or specific volume or temperature, etc. Unlike these state or "point" functions, heat cannot be expressed with an exact differential.

Maybe this made some sense, though it's probably not a satisfying answer. An actual physicist will know more, but the real answer will always just be "because just the universe just happens to work that way for God knows the reason."

Okay, but I'm not being gang stalked and don't have an anal implant. Are you homeless these days, Jon?
