Undergrads are generally overqualified for that, so not. Alumni segregation by capabilities and skills would make HS better.

My old high school had about a 5:6 PhD to pleb ratio in the sciences. It was called "St Paul's School" and was in richmond i think.

It was kinda weird - what kind of a human is going to spend several years completing a PhD and then spend his vast knowledge tutoring teenage retards?

But it was nice to be able to chat to these experts regularly, and I miss that kind of frequent contact now I'm at uni.

ITT I will try to summon Emma-Stone-fag. We recently had a discussion, allegedly with you, on computable/constructive spectral theorem.

Namely, if [math]A[/math] is an [math]n \times n[/math] complex-valued matrix, then there NEEDS TO EXIST an approximate spectral decomposition that is effectively computable/constructive. This means that there need to exist approximate eigenvalues [math]\alpha_1, \ldots, \alpha_n[/math], approximate eigenvectors [math]v_1, \ldots, v_n[/math] such that [math] \| A v_i - \alpha_i v_i \| \leq \varepsilon [/math], approximate projections [math]P_1, \ldots, P_n[/math] such that [math] \| A - \sum_{i=1}^{n} \alpha_i P_i \| \leq \varepsilon [/math] projecting onto invariant subspaces whose dimension and bases can be effectively computed and the whole space decomposes into a direct sum of those.

You recommended to contact some bigshot in this field. Apparently, they don't even notice messages among shittones of spam. If you have contacts to them by any chance, please ask. This problem has a number of serious consequences.

>>8036202
nigga no need for no big shot
1/fix an epsilon
2/start with the classical algorithm to find the biggest eigenvalue and an associated eigenvector (power method or a variation of the power method)
once you have that, you see that you only need to scale the eigenvector v1 you found so that ||Av1 - a1 v1||<epsilon.

Now you can just repeat by changing the matrix A into a matrix restricted to a subspace that excludes v1.

Eventually you get all the eigenvalues you want, the associated eigenvectors...

Seems hard to believe. A can be any matrix? Not just hermetian or normal? Are the v_i supposed to be nearly orthogonal?

Seems like you are saying all matrices are nearly diagonalizable.

More diseases are being discovered and the scope of prior diseases are being redefined. As you so very clearly illustrate yourself, mental health has very ignorant connotations associated with it and it's important to point out that not everyone who has some mental health related issue is a stark raving lunatic who has to be locked up in an asylum for the rest of their life.

You wouldn't find it odd for a doctor to state that >=50% of humans will experience at least a cold in their lifetime, and will at point during this benefit from a cough drop or aspirin....

I am a freshman at my university and I have programming One among other classes. My math skills suck ass and so I am doing college algebra (which is too fucking easy but I'm getting there), but I think I failed my first test since high school today.

The test was mainly on arrays and 2D arrays in Java. From a guy who has been doing really well in the class so far (96/100 total grade), I feel like absolute shit for what I believe is bombing this exam (probably scored a D or a C).


Is there any hope for me, /sci/? Can I still become a programmer? Did you awesome...

>>8035227
Advanced dildo manufacturing.
>>
>>8035227

I would want to enjoy the subject and be of service to my students, and it would have to be something that I actually understand from multiple angles and have a personal track record of helping others to understand (or remember) if and when it becomes necessary.

So something in high school algebra/precalc/calc territory. Not qualified to be a uni prof famalam. Also HS kids are less insufferable than middle schoolers, the worst of the worst.
