flip and resize your picture
check some usual sorting algorithms and see where they are different from yours
count the number of operations yourself and see where there might be problems
do your homework by yourself

Thoughts on book encyclopedias?
Do you find them outdated and obsolete now that we have wikipedia and the internet?
Do you own a set?

>Thoughts on book encyclopedias?
I find them outdated and obsolete now that we have the internet.
More over, I argue they were never most useful, as it's always been better to have many good and focused books about one subject, than one shallow book about many different subjects.

You're an idiot.
Encyclopedias are meant to give brief summaries.
The entries are well written and generally still valuable.

>believe that you are being secretly poison and god
Yes, yes i know that being a mathematical logician is not the same as always thinking logically, but i just find it ironic sometimes
Is there a difference between scientific/mathematical and practical intellect?

I have a hard time recovering from mistakes, regardless of the context or magnitude. I feel I have permanently proven that I am intellectually inferior. The feeling always recedes eventually but the wound is susceptible to reopening with further mistakes, which I inevitably make. Do any of you struggle with this? Have you found any coping mechanisms for reducing the time lost ruminating on your continually renewing status as a moron?

It's like looking to a mirror.

Yes.

I wish. Some people both here and IRL have tried to help/convince me, but I always feel I can't trust their judgement, since I'm the only one inside my head and I only see a fog.

This is the only thing worth of your entire post.
Yes it is. And you won't do it because you only come here to spout bullshit and feel better without doing anything until you fail again.
That's the average life.
The only solution that will make a difference between commom scholars and you is to master basic mathematics until calculus.

I met a market maker a little while ago and he said he got hired because he did a phd in discrete math. I'm interested in the field and I'd like to read some such papers to see if I can understand/decipher them.

Usually professors link their dissertation on their website.

If they got published by a scholarly journal, then yes. However, you'll need access to a database like JSTOR which can be expensive if you aren't part of a school.

No long term studies I know of; obviously chronic, frequent inhalation of smoke is detrimental to cardiovascular health. On the anictodal side any ex-pot head can attest to the permanent impairment of short term memory, and active smokers experience significant mood swings and some general cognative imparement between highs, much as a smoker gets on aggravated and lethargic after going hours without nicotine, or an alcoholic experiencing the same after going hours unintoxicated.
It will probably be several years before studies have any sizeable long term data on marijuana abuse.

So doing some random maths for school and thought about root 2 in relation to triangles. If you have a triangle and 2 sides are equal to 1 and the hypotenuse is equal to √2 then how does the hypotenuse end? √2 is an irrational number and the decimal never ends or repeats, but shouldn't it have to end at some point for the line to end in the triangle or does the line keep going on forever? Which wouldn't work when applied to real world geometry.

The number represents a real length that would take an infinite amount of time to measure precisely. That doesn't mean the length is infinite.

because CS hardly ever actually means CS, it means "generic shitty computing program for brainlets who want to do TI or something"
also what you listed is a CS/Math double major:
CS:
>Algorithms
>Data Structures
>Computational Complexity
>Cryptography
>Machine Learning
The rest isn't really core CS, you will use only the most basic stuff of fields like statistics and number theory unless you specialize on them
