But most who mention suicide casually are not necessarily self destructive but definitely hate their lives.

How do we measure and compare the different fields of intellect?

Level of intellectual ability required to not only understand the concepts but to make profound leaps in understanding leading to new ideas

Calculus and Linear Algebra. They are your friends. Pretty much cover up everything you need for undergrad. Learn them enough to understand some optimization algorithms. Discrete Math is easy af. If you can't get 4.0 I recommend you to quit asap. Stop wasting everyone's time.

Learn some set theory and proofs, that comes into play when you learn algorithms and computability

How to Prove It - Velleman
Book of Proof - forgot

Those are pretty good books you can go through but be ready to rigorously prove some extremely mundane and painfully obvious shit. You technically could go through Spivak, but trust me it won't be worth it for the path you're going down.

>>7950790
why don't you think Spivak will be worth it? Does Calculus not play a big a factor in theoretical CS?

Yeah, but it's at twenty times the pressure required to make industrial grade diamonds- that's not practical at all. Call me when there's a breakthrough, not just guys dicking around

>>7950465
number 2 is correct (not sure if you were also supposed to specify some weak acid to catalyze it).

there's something wrong with number 1: cyclohexane is not very nucleophilic, probably you are not recalling the presence of some functional group.
Furthermore, under Lewis acidic conditions the epoxide will be attacked at the more hindered position.

#1 wouldn't react under those conditions.

If it was benzene, would that change it? I'm pretty sure there weren't any substituents on the ring. I was pretty confused. His hint was "Oxygen loves Aluminum!" which I'm not sure what was intended by that. I've never really seen AlCl3 used outside Diehls Alder, anyway

I looked at linear slides, all the ones I looked at simply popped out and return. I think they were intended for assembly-line applications.

XY linear stages were almost all too small.
The 3 or so that were 0.5-1 m^2 were $10,000 or more.

Linear servos weren't long enough, or were designed for hobbyists. Again, I need something better suited for commercial/industrial use.

Almost everything I saw was not meant for positioning *anywhere* on the stroke length. Rather, they were for extending...

it's not so simple...

As an engineer, you should count $10k for every degree of freedom on a factory robot, which would make what you ask, all costs included, $20k

For an XY machine, the system is overconstrained, and 5kg is heavy.

Have you considered a robotic arm like pic related?

There would just be some suction. Your finger would be fine.

You could compare this to Delta P diving accidents. The pressures there far exceed 1 bar and yet the divers are just held in place and not shredded up or something.

You're working against pretty low forces here so I think you'd be able to just pull the finger out.

In highschool I viewed math as a means to getting the right answers on tests. So I forgot anything I learned pretty quickly despite getting good grades.

Lamentably autistic faggots of this board hate philosophy. You can find help in /lit/ or /his/.

I actually love philosophy, especially theory of science.
Wittgenstein's is the second most interesting philosophie, because his approach of understanding language is the promising. When you got the key to language you got the key to everything imo

I'm not sure what he told about math, but I'm eager to read.

here are some examples, but best pictures for simple orifices ive seen are in first source. lefebvre is really profitable lecture!

like pic related, there are different regimes starting with breaking down surface tension forces (this ends up at hyperbola OhRe =2 for simple orifices) after that jet is passing through the other regimes until complete spray formation. so you cannot say what is occuring that easy. in addition real processes are instationary for normal...

it's that when your eye sensors see the same thing for a longer period of time, they get used to it, so when it stops they start seeing the opposite.

they are trying to understand,nobody is capable of being right exactly every time.
As stated above,you know science is progressing when they are proving themselves wrong.
So please stop be an idiot and appreciate it.

yes I do.

What I don't appreciate is using inaccurate models to predict things that are used as the scientific truth.

damn that's a diss of a URL

Anyway, they try. Much of human endeavors should be interpreted as a struggle against the impossible. Like how medicine tries to save the elderly, climatology tries to make predictions about an absurdly complicated system. In both cases the people involved know success will be limited.

Hmm... That kind of existentialist talk makes me want to study the numerical solution of stiff PDEs some more.
