It is time /sci/, let's have some fun with ourselves.
I'll start: 2
I'm going to do medicine next year, what do I study in the holidays?
Can someone recommend me textbooks for a good intro to topology and modern algebra?
All I've taken is linear algebra and set theory
THE WHOLE WIDE WORLD BTFO
Can anyone point me to the science behind this stuff? Papers on the process to make it/general ideas behind it. It seems super interesting.
This looks fantastic, except it costs 36$. Is it possible you could point me to a resource that doesn't have a paywall (a tall order I know, I apologize).
Will high-powered portable lazers replace guns as the main weapon for criminals and for self-defense?
What comes after guns /sci/ ?
Yes. Weapons that slowly burn tiny holes instead of imparting force and that can be easily reflected are going to replace guns.
If nuclear fusion is ever miniaturized to the point of being able to be used in vehicles, we might see tanks that use laser or directed microwave weapons at extremely high levels of power, capable to near-instantly melting anything that they can see, which would have advantages in direct engagements but be useless in indirect ones.
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..
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)
Do you think is ok that some students fail science and engineering courses just because the made some algebra or arithmethic mistake on some test and teachers doesn't care to check if they understand the concepts just follow recipes and follow procedures?
>Do you think is ok that some students fail science and engineering courses
Yes. Scientists and engineers need to calculate values.
For mathematics, no. You should never be allowed to use a calculator in the first place and if you make a sign error or whatever you go back and fix it.

>Get Dave to run PCR on the isolated DNA.
Why does DNA have to be amplified for the suspect to be caught?
I am confused because this is the way I see it: I have 1 bar of chocolate and I tell the chocolatier to melt it down and make me 10 bars of chocolate so I can see what it is.
I am a bit confused, since I passed my course in linear algebra few years from now.
If I can make a vector space over field R which has angles as elements, then angles are vectors.
So i know that angles can't be vector, but I see vector space (V, +, *), where set V contains some angles in Radian or whatever and I can see that these condition work.
1) (V,+) is a group
2) a*(u+v) = a*u + a*v
and so on by definition.
So what am I doing wrong?
Ive posted this for the past week straight and still no replies.
what does /sci/ think about a micro-biology major?
and what about bio-physics?
is it REAL science, and perhaps even BIG science?
>what does /sci/ think about a micro-biology major?
If you want advice regarding college/university or your career path, go to /adv/.
Dont let sci dictate your opinion on science or major.
Microbiology is good and its a good major.
It is "real" science or whatever that means. Its applications are one of the most useful and its on a new frontier of discovery.
Micro-biology needs good chemistry knowledge tho so dont skip out on those.
Im not sure about biophysics but certainly its applications are equally important, as the field of biotechnology is growing and seems like the way to go.
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.
Is 29 too old to begin a career as an electrical engineer?
Do you guys think someone who is "good" at writing fiction is as skilled and intelligent as someone who is good at high level math? To me it is laughable to even think is.
you are insecure
you need validation from other insecure anonymous mouthbreathers
they will tell you what you want to hear
they will tell you what you don't want to hear to be contrarion
you already knew this
How fast is the earth moving relative to a stationary object?
Relative to the stationary objects on my desk, 0 km/s.
Relative to the sun, about 30 km/s.
The sun orbits the galaxy at about 200 km/s.
Relative to the invasion fleet from Tau Ceti, we're moving about 0.33c.
