Can I teach myself linear algebra in 2 weeks? I'm bored as fuck over break and want to git gud at linear algebra cause I'm taking it next semester, should I just watch YouTube videos or what?

For the record I thought the answer was 5 but it's actually 60 according to the key.

Hillarious, it is one of two physics and math oriented unis. The other one sits at top 250-300, not sure if u would cut it since most smart people in my country go there, while im a brainlet.

But it doesn't work like that I think. For example, it's know than your consciousness die everytime you sleep and when you wake up again the brain just activate a copy of your consciousness made before you went to sleep and lost it. But I mean, you really don't realize that your consciousness have died thousands of times and you are just a copy of your yesterday self. Please, explain this to me because I really don't understand.

Thought I was around average intelligence, perhaps a little below. Had great GPA in high school and pretty good first year of college. Is there any training, pill, or surgery that can help extreme cases of stupidity?

Char is a variable type. Look up functions.

Are particles physically real? Are they just mathematical/conceptual approximates of phenomenal experience? What I mean to ask is: is it possible that our theoretical constructions of atoms, electrons, etc. are accurate enough to produce verifiable results, yet the reality they represent could be radically different?

>Dynamic programming task
I am not really good at handling dynamic programming problems(brainlet).

Given integers [math]a, b, c \ (1 \leq a, b, c \leq 2^{30})[/math] I have to rearrange digits of their binary notation to get the following relation: [math]a' + b' = c'[/math] and this [math]c'[/math] has to be smallest possible, the output is [math]c'[/math]. In other words, the program has to output the smallest integer with exactly [math]k[/math] 1-bits in its binary notation that is the sum of two integers with exactly [math]m, l[/math] 1-bits in their binary notations respectively. For example, given [math]a = 4, b = 8, c = 3[/math] (two numbers with only one 1-bit and one with two 1-bits) the answer is [math]3[/math] as [math]1 + 2 =
3[/math] (still the same number of 1-bits as in original numbers). Of course such an integer may not exist.

This problem is supposed to be DP one but I don't even see what is the subproblem in this case so there is no chance I come up with DP relation with my current understanding of a problem. The only thing that comes to my mind is that this problem may involve an array of length [math]32[\math](for each bit).

Please help a brainlet...

Need an advice on how to approach the following NP-hard problem:

Given a sequence tan(1),tan(2),...,tan(n) insert '+', '-', '*' to minimize the absolute value of difference of n and value of resulting expression. (5 ≤ n ≤ 365).

I know very little about approximation algorithms for NP-hard problems and I'd be happy if anon could give me a general idea how to approach this problem or what this problem can be reduced to or whether it is a generalization of some well-known NP-problem so I can google more efficiently.

Any brainlets on /sci/ who were bad at math/stats and turned it around? How did you do it? I seem to study forever, but when I get to answering a question, I just completely go blank.

Is there a book any of all niggas can recommend to a guy trying to logic a shit?
I'm not a math autism so no functions plz.
Is this a good one?

I tried reading Stanford encyclopedia and I got lost. My adderall/coffee hasn't kicked in so that could be it.
Will learning logic first make algebra easier?

>the foundation of science is the scientific method
You mean empiricism and rationality(sensu epistemology) to experiment? The scientific method is just how you test a hypothesis you absolute brainlet. Underagedb&

/math/ why waste your time on physics and computer science when you could be making significant contributions to the life sciences? It's is where the frontiers of theoretical science are, also it is infinitely more interesting and applicable to, well life.

What are the best drugs/ supplements for brain fog?

>tfw want to study all the time
>have to eat
>have to shit
>get distracted
>get tired

when are we getting external hdds for our brains again?

>enter engineering program at my community college
>freshman level courses require me to take 2-3 prerequisites each
>passed the entrance exam with flying colors
Should I just give up?

Anyone who believes in determinism is a brainlet.
