Alright /sci/, I need your help.
A few days ago I posted about being interested in buying a microscope to fuck around with.
I just got payed two pay checks, and I have some money to spend.
Would it actually be worth it to buy a microscope, or is this something I will just use once and have wasted a bunch of money on?
Is it actually worth it, or is there cooler stuff out there I should be spending my money on?
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
/k/ here, I know that there is some way you can change a traditional electric motor to make it an electric generator, and I feel like this would be helpful in a SHTF scenario, does anybody have any sources on how to do this or how generators in general work?
>>9082934
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.
Since P=NP, N has to equal the multiplicative identity so that P=(1)P ergo it is true for all values of P.
Why do people have trouble with this?
>>9082893
It could also be that P=0, as 0=N(0).
>>9082893
>circular logic
>>9082893
Whatever the fuck you are talking about, your "proof" is wrong no matter what because you used circular logic.
this warning only shows up when you search for weather on the west of the cascades, lmao
bitch ass liberals

>>9082891
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"
>>9082879
Pure scam.
>>9082879
Huge scam, insurance companies WILL use your data
>>9082879
Scam
Would /sci/ be abled to figure this out?

How did you master control engineering? You own project? Just lecture/books? I have to spend the next 7 month with this and want to get the most out of it.
>>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.
I just went to a restaurant restroom, and they had two mirrors facing each other at 90°
For the first time I could see myself how others see me (my left looks right)
It was fascinating and sad at the same time,how our brains F**in work
Welcome to the water....

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.
Is that the conceivable end it are popscientists correct in saying a sufficiently advanced civilization can tough out the dark eon until quantum effects spark light back into the universe (or they just leave entirely).
>>9082804
ENGLISH MOTHERFUCKER DO YOU SPEAK IT
>>9082813
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.
Does anyone here have a masters/working on a masters in statistics? I'm currently working on a bachelors in economics/minor in statistics at one of the top public universities in the country, and statistics has always fascinated me.
Unfortunately there isn't a bachelors program for stat, or else I would be doing that. But from what I've found, statistics related jobs are expected to increase by 34% between now and 2024, according to the BLS, with a pretty high starting salary(~$75k). The majority of the jobs require a masters though.
Would it be worth the debt? I'm not sure what the total cost is going to be, but I'm thinking about TA'ing to offset the cost if I get accepted.
Fortunately, my undergrad is paid for, but I wanted to see if anyone here can verify the starting salary and tell me what to expect with the whole masters program in general, before I decide to take the plunge in a year and a half or so. Also, if its not too much trouble, could you tell me what exactly it is that you do(academia, insurance, finance, etc.)?
Thanks for any input.

Woops, sorry about that, should have read the sticky.
Mods, feel free to prune this.

msc in statistics sounds mindboggingly boring
Like lets say if we presented a genius with a simple fraction question, would the genius be able to answer it correctly or would he be stumped like everyone else until they are taught how to solve it?
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
Do questions about computer science topics belong here or in /g/??
I'm curious about the benefits of learning C. Does possessing an in depth knowledge of C really contribute to a more comprehensive knowledge of low-level computer systems? Would I be better off just fucking around with assembly until my eyes bleed?
Is C still relevant in fields like robotics/electrical engineering and machine learning?
>>9082702
>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...
>>9082702
>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
Can anyone figure out this code?
What does it say?
here is another line
Fuck you
Need some help
I have this test result which states:
Flow time : 65 s
6 mm
Method: ISO/DIN 2431 '84
I want to convert this to viscosity in units of mm2/s or cSt.
What do I do? Simply find the area assuming 6mm is and divide to the time elapsed?
I'm not familiar with the method ternet wasn't very helpful either, for some reason accessing the details of these ISO methods require money
