can anyone explain what the overflow detection mechanism works in a 1-bit alu? i dont understand how im suppose to make this module. i have everything else set up starting at basic gate levels, then building up from there, using 1/2 adders, to make full adders, 2x1 multplexer to make 4x1 multplexer, but i dont know how to design the overflow detection at the gate level, and all diagrams i find just have a 5 wires going into the circuit, and 1 coming out. so i dont really know what it is..

potato quality pic, my bad..
I'm not an EE guy but i know a tiny bit about this so I'll try to answer
AFAIK, it's exactly the same as the "carry the one" part of the adder, except instead of feeding into another adder (adder-chaining addition model) you just feed it to an output pin (e.g. with an 8-bit addition circuit, 255 + 1 would result in a result of 0 with overflow bit set since it cascades towards the MSB)
>>7713097
Overflow for a 1bit alu is simply carry out.
For an n-bit adder the carry out for the last adder is the overflow signal.
I want to have my left eye remove so as to give me ins to getting cutting edge robot eye technology
What kind of accident could happen where I walk into a hospital or call 9/11 and a surgeon has to remove my eye.
What could I do to trigger this accident without causing me a great deal of pain and doesn't risk me dying or getting infected or something.
plz guys

Does the 3rd law of motion apply to the energy a bullet has when it exits the barrel of a gun?
For example 7.62x54R has a force of 3,779 J when it exist the muzzle, does that mean that the kick back onto your shoulder is also 3,779 J, or does the weight of the rifle mitigate the reaction force?
If so is there a way to calculate the force on the gun and the force imparted onto the person?
>>7712588
mass of bullet is small compared to mass of gun and mass of person
the 3rd law does apply, but for a small caliber like that, it doesn't amount to much kick.
there are some rifles that will bruise you pretty good if you shoot them enough times
also look up videos of rpg's bazookas, and other artillery. you'll clearly see people get knocked on their asses from the shockwave created from the explosion
>>7712588
Joules measure energy, not force.
>>7712588
yes, le gun magix dont remove physics .
also there's a lot more variables that go into the kick back onto your shoulder then just energy , there's the momentum of the gun moving back and hitting you there's the speed the energy is transferred to your soldier .
you could say when you shoot someone you get 'hit' with more energy then they are , its just that they are getting it all very fast and concentrated and you're getting it really slow and kinda spread out from the stock of the gun .
If I want to become a high school STEM teacher, would I be better off getting an education degree, a STEM degree, or something else?
>>7712497
STEM plus your university's teaching option in the degree (e.g. UTeach for University of Texas). Unless you're bad at math then do education.
>>7712497
doesn't matter really
If you get a teaching degree, you have to teach, you take less STEM courses and more education/humanities courses.
If you get a STEM degree, you lose out on the teacher training stuff, but you can work elsewhere more easily. With a degree, you can work as a substitute teacher and then get your teaching license after.
STEM, then do your Teacher Training
do ants have free will?
>>7712481
No, the only animals with free will are goats.
No, they aren't conscious. They are purely instinctual animals.
(Idk wtf I'm taking about and am tired of the free will meme)
>>7712481
Free will is physically impossible.
Wannabe sciencefag here, could anyone explain why proving that neutrinos can change from one type to another prove that they got mass?
>Wannabe sciencefag here,
ok

Start small, lil' nigga. A reasonable answer to this question requires a lot of in depth knowledge of quantum mechanics and particle physics.
>>7712372
>Start small, lil' nigga
How small, Bubba?
>>7712372
>requires a lot of in depåchef knowledge in quantum mechanics and particle physics
Yeah i got that. Please explain.
What are cool applications of it?
My linear algebra class pretty much only focused on theory and proving stuff, with only the odd practical example.
>>7712162
Mostly all physical sciences/math. But there are an odd-ball or two applications to social sciences/marketing (mostly simple linear regression though). Quantum Mechanics is a biggie.
>>7712162
Sparse matrices are useful in natural language processing. SVD is used for dimensionality reduction and you can do all sorts of calculations with the row vectors of a WORDSxDOCUMENTS matrix
>>7712162
Data Mining uses it extensively. So does anything involving graphics. Your computer's GPU? It's a linear algebra machine. Data Science in general uses linear algebra a lot.
I hear engineering (real engineering, not "put engineering at the end of every adjective" memery) uses it a lot but I'm not in that field so I don't know.

What the hell is "real analysis" and "calculus"? In my country, we have "mathematical analysis I-III" courses, where we deal with differential and integral calculus (single and multivariable), metric spaces, infinite series and basics of vector analysis and ODE (not in this order). From the beginning everything is done in a rigorous manner with proofs. My assumption is that "calculus" is just analysis without proofs and "real analysis" = enter epsilon-delta. Am I Correct ?
>>7711942
The courses you described are calculus courses, not analysis.
>>7711942
Where are you form?
>>7711942
Ayyyyy lmao Real Analysis is stuff with sequences, limits, compactness, limsup/liminf, series and all that jazz. Sorry I'm drunk I can't really explain it that well, but basically real analysis is harder than your usual stuff breh.

Not so hasty.
They're just proving that the plasma could be stable. And they apparantly did.
They're going to try again in januari, but with hydrogen.
>>7711856
Source? I can't find any articles about this.

>They're just proving that the plasma could be stable.
What's significant about that? The Brits did it year's ago, the problem you only get something like 0.65 the energy out that you put in.
How do i master Wolfram Mathematica in 3 days.
Note my programing skills are low tier.
>>7711767
Install Gentoo
>>7711770
its for an exam where its required to use mathematica.
>>7711767
By learning Maple instead
anyone know where I could 'Classics in Total Synthesis III' from KC Nicolaou from? libgen has nothing
bump
p-plz
Do you guys have a large collection of textbooks like Gentoomen's Library?

no, because i only have 3 texts that were worth keeping throughout undergrad
>>7711712
Common core is right tho. Formally speaking 8+5 is (((((8+1)+1)+1)+1)+1) which is also equal to (((10+1)+1)+1).
Anyone have any experience with putting a matrix through a linear equation? Drowning computer science major here. Googling extensively isn't getting me anywhere. Any help would be greatly appreciated! (:
>>7711524
It's been a while but just input the matrix into the function and keep doing the operations until you have a final matrix.
It's tedious, but not difficult.
>>7711526
Do you mean first taking the matrix ^3, minus the matrix multiplied by 3 and ^2, etc? Before I was just taking each number of the matrix and putting it through the equation.
>>7711524
If the point of that exercise is finding nth powers of square matrices easily you should look up eigenvalues/vectors and diagonalization of matrices. Otherwise you can just do it the slow way, which in this case may be faster.
Im curious as to how good the math niggas on /sci/ are when they are handed an actual problem, since proofs these days can be regurgitated by anyone. Ill start off with pic related. If we substitute every circle with spheres, what is the total Volume of all the spheres? If you need an explanation behind the pattern of the circles, Its a dead ringer that you are not capable of solving said problem.
>>7711485
the answer is:
Go away. You're a shit poster and this is a shit post.
>not capable of solving
