They're right, you know. The assumption that there's "one right answer" to a given mathematical problem reinforces both white supremecy and paternalism.
Thoughts on this? How can we make math more anti-racist?

It is somewhat true. I've always suspected that it would be more difficult to make students solve a problem with more than one approach, but that this would have enormous long term benefits to his creativity.

QFT not mathematically rigurous, says the physicist

Quoted By: >>14341930 >>14341939 >>14341987

Haag theorem says the so called interaction picture as seen in QFT doesnt exist. The S matrix is assumed to be unitary "like a rotation" and found not to be unitary. Interaction hamiltonian said to be a non existent mathematical entity.
Physicists casually state these things and then say "but it works muh beauty".
How do you consciously do shitty mathematics and find out (sometimes) good results?
Having computers algebra on hand, isnt it much easier to just solve these non-lineal interaction lagrangians with brute force and infinite series and deal with it?

QFT suggests that matter doesn't exist, it's all waves, but since we can only perceive and contemplate matter we cannot make any testable theories about the waves. We got a glimpse of how the world works but we're made of the wrong stuff to actually know about it. We can solve all of the equations we want, but unless we can become as waves ourselves and get outside of the universal wave function, we cannot prove anything more.

technically wavefunctions can't always transform with unitary transformations since particles can be made and destroyed.

>since particles can be made and destroyed
In QFT these are simply state transitions. Its an issue of language, when you study transitions of an electron in an hydrogen atom you dont say "and here the electron was destroyed and a new electron was created at a different orbit". In QFT a particle is just a vector of a basis in a vector space with some coefficient and "particle destroyed" means the coefficient is zero.
Same as with the jumps of the wavefunction collapse during a measurement, the wavefunction as a whole gets projected and many vectors essentially get multiplied by zero. Its still a kind of rotation and its unitary.
But it doesnt work when your "hilbert space ket rotation operator" isnt unitary and doesnt preserve the state vector modulus

Resolution for any imaging device is measured as an angle and is inversely proportional to its aperture. (Also depends on the wavelength of incident light) My 254mm dob, for example, has a resolution of about .5 arc seconds. Of course, the atmosphere limits this to around 1 arc sec. The JWST with its far superior aperture and location obviously has incredible resolving power.

Correct me if I'm wrong, but whit 'traps' we are talking about defects in the crystalline structure that trap electrons. If so it kinda makes sense that it's only a problem with high sensitivity IR sensors.
The cited article that goes into the physics and effects on IR arrays is behind a pay wall.
