>I know the basics

Ok, now get the following books:
Fleming's Frontier Orbitals and Organic Chemical Reactions

Deslongschamps' "Stereoelectronic Effects in Organic Chemistry"

Grossman's "The Art of Writing Reasonable Organic Reaction Mechanisms"

go to bookzz.org and go nuts

>>8141651
there is no "most crucial part" as to why a reaction will or will not work
you have to consider sterics, electronegativity/electropositivity, orbital theory, inductive effects, solvent effects, and a ton of other factors when determining if a reaction will work
there isn't a set formula for these things, a large part of it is intuition and understanding how these things work together once you understand how they work separately
stop trying to apply the same methods you use in math/physics
chemistry exists in the real world and isn't the idealized model of a system, there are too many variables and factors that we don't know about so you can't solve these problems like a system of equations

complete and utter bullshit

Because science is not a dogma which nobody is forced to believe ? And the outcomes are entirely dependant of the objective results of repeated experiments ?

>Isn't science just another spook?
Nothing is a spook unless you let it be.
Someone like Perelman seems to be severely spooked by his Russian perspective on pure math.

>Do you only use theorems you have checked by yourself?
Nobody does, unless you're doing the most basic pure logic. But that's irrelwvant here. Don't throw around a naive notion of truth.

>Do you use the axiom of choice or not? Do you assume law of excluded middle?
Hardly anybody on /sci/ does actually do nath where it matters. Maybe nobody here actually does (as opposed to: reads about) the functional analysis where it's actyally used.
I'm personally not a fan of all of ZFC but that has completely zero to do with the cteative nothing.

>No more true than some babbling of a 3 years old child, which accurately expresses toddler feelings.
No it seems much much more that you are or would liked to be spooked by science. You do hope for an objective truth.
How toddler Wittgenstein relates to truth of published math papers doesn't matter. Toddle sentences are not fur nor get you fame. They are not of utility.

Why would you need a textbook for matlab?

>>8141577
I enjoy having textbooks to supplement my learning

>>8141580
But there's nothing to learn. Just ram arrays down functions and press help when you forget what a thing does.

Google Books has it.

Read anything by Dover books. Everything they print is pre 70's just about.

It can cross. If a node is hanging you have to go back to his previous node

>>8141390
Sorry I should be a bit more specific:

With a given matrix of dots that you can travel from one to ANY other dot (no limited movement)

And you need to traverse it with salesman rules (visit every dot once and get back to start)

Will your shortest path ever cross itself?

>>8141398
No.

>>8141374
Going to give any details at least about this breakthrough?

>>8141502
It is about capturing data from 5 dimensional space from 3 dimensional viewers perspective.
It kinda sounds meaningless but this math was required for some research in physics which is going to start in a few months

It's an all sky map of the CMB. Use google.

>>8140955
Its what the universe looks like from earth

>>8140964
No it's not, unless you "look" with an extremely advanced and specialized microwave detector.

>Failed twice because of avoidant behavior

I swear if schools just allowed for regulated consumption of weed before major tests this wouldn't be such a common problem.

I have pathological anxiety that manifests as avoidance when not managed properly.
find a therapist.

>>8141073
How does one go about finding a therapist, preferably psychiatrist, without using parent's health insurance?

You are retarded.

I suggest reading flatland maybe watching the video made by Carl Sagan would be easier.

>>8140638
Do you understand what dimensions are?
We can't actually visualise a fourth dimensional object.

>>8140557
the first one is neat, the following lines, however, are less impressive - and you should be able to see why..

>>8140563

I SEE WHY

NAO EXPLAIN THE FIRST ONE

yes, everyone that sucks at math is a genius that will revolutionize physics.

In related news, Darwin was said to hate vomiting, and I hate vomiting so I know I'm going to be a great evolutionary biologist.

It is a myth. In fact, before he was 15 he mastered differential and integral calculus.
