if you're gonna buy a microscope to fuck around with, i'd get a lab surplus dissecting scope, like http://www.ebay.com/itm/Nikon-SMZ-1-Stereozoom-Dissection-Microscope-7-30X-Missing-Stage-/292176671893?hash=item4407163495:g:wp4AAOSwfpVZODVI

honestly most of the cheapshit microscopes on ebay/amazon are garbage. you're going to use it once and be disappointed with it, i think.

try to stick to more established brands, like nikon/zeiss/etc, not stuff like amscope

i have a cheapshit dissecting scope and i use it for looking at stuff eveyr now and then and i like it. I can look at larger objects that can't be slide-mounted. it's basically a big loupe or magnifying glass. it's nice to have

If you're talking about a DC motor, then you just drive the shaft and wire it backwards.

>>9082957
You don't even have to wire it backwards. Just drive the shaft, and it'll feed voltage back into the system. You might have to open up the motor to modify the gear train, though.

At the front end, there's the problem of what will turn the shaft, and at the back end, there's the problem of how you'll store the power.

It could also be that P=0, as 0=N(0).

>circular logic

>>9082893
Whatever the fuck you are talking about, your "proof" is wrong no matter what because you used circular logic.

I grew up there and 85 is abnormally hot summer temperatures. Anthropogenic Climate Warming in action.

looks like Alaska is the only retreat left to escape the hellish summer temps.

>>9082904

then again with the known faking of weather temps, it could be the same temp as always and they just see "90/100" "wow it is kinda hot today"

Pure scam.

Huge scam, insurance companies WILL use your data

where is that thing now? i bet it hasnt event left solar system

>>9082852
At first its easy. It gets nasty very fast.
I took a numerical methods for control systems.
If u had not mastered numerical methods in linear algebra, ure fucked.

>>9082878
I guess that's a good place to start

>>9082878
Which parts of numerical methods, mostly? Asking so I can review.

The fact that you was obviously never took in picture (otherwise you would've noticed this already) basically tells u that ppl find u ugly.

Sorry, phone posting.
Basically, are popsci theories on circumventing the final boss of the universe actually possible?

>until quantum effects spark light back into the universe
This made me giggle.

msc in statistics sounds mindboggingly boring

If he literally never seen math before in his life, no.

Well, I'm glad you asked me this, because I happen to be a genius. (Or at least mommy always said that I'm "her little genius")

The answer: Even a genius needs to be taught the meaning of the used symbols first. Then, theoretically, he could figure out all the theorems and solving methods/algorithms themselves. Basically, you'd need to combine Ramanujan and Neumann.

if he's capable of reinventing theorems he could've learned then he wouldn't 'need' to learn them, but it would be a waste because he might as well catch up to the current knowledge and spend his energy on things that haven't already been done

>Is C still relevant in fields like robotics/electrical engineering and machine learning?

C is usually taught on the first semester in EE and SE courses. look it up and you will see I'm right and that says it all.

I'm at a community college before I start my EE program. I've only covered maths and fucking humanities prerequisites, so.... I guess I should learn some C before I start at big-boy school...

>machine learning
No, ML frameworks are usually written in C++ and called from Python/R.
This is not a fucking CS question, but a coding one. Come back when you have questions about Turing completeness and computability
