Is the Laplace transform an meme and a crutch?

nice bait, but for engineering majors this is true laplace is a meme from diff equ. can almost always write as a system of linear first order equations, diagonalize and apply matrix exponential.
How do I get a 99% in the SAT 1 Exam? I know it isn't a hard test or anything but I don't want a 80% or 90%, I literally need to be the highest score or I won't go to college. I know this part is easy, basic reading, writing and math skill but still
Your best strategy would be getting your parents to pay for a tutor to make you practice SAT questions 1,000 times so that you have an unfair advantage among your peers.
>>8000472
math is easy, language you need to study vocab shit and have good reading ability.
>>8000477
the reason I have to get that score is because I'm a poorfag and I need that for the only scholarship I can maybe get, so I'd rather find free online resouces or torrent a couple books
I don't know if i want a degree on computer science or mechanical engineering, so i was expecting if some anon can help me solve this with some intel:
- i really like mathematics
- i really like the physics problems(they feel intangible/mysterious i know it sounds cringy), they seem like they have some porpose( something more interesting then autisticaly solving math equations without seeing it being applied in reality...like it's not enough)
-i really like how optimizing computer science is to solve problems (like creating softwares to attend our needs)
-i've...

you have to narrow down your interests in math and physics first to make a decision, really

do Mech E and learn how to write simulation software. CFD and FEA make fucking bank. my former gas dynamics teacher is working for Lucasfilm making more realistic sandstorms on tatooine or some shit.

you mean find out precisely what i want from each one?If it's the case it would take a lot of time...like a degree's
Hey /sci/ how would I go about cleaning unknown chemicals out of a Buchner funnel/flask? I've got two of of pic related, and a few other things I came across.
just dump it down the sink who cares

Oy kiddos,
did you ever realize that some people's memories are in color, while most people remember everything in black and white?

>TV shows shitty turkish love songs
>Make fun of "remember" scene in love song because black and white
>Friend tells me she remembers everything in b/w

What? Do you have a source to back that up?
Did more than just one friend even tell you this?
I can't say this is true for me, at all.
OP here
By now I asked all my friends and colleagues. Around 70% say that their memories are in b/w
Do you ever think about how alien civilizations would have developed differently under different circumstances?
For example how would a civilization on a planet with very little oxygen have progressed? Fire/combustion/combustion engines might not have been developed.
Would a civilization a planet with lower gravity and/or thinner atmosphere have developed space travel much sooner than we have? For example, getting into Moon orbit from the surface of the moon requires about 1/5 or 1/6 the delta-v required to get into Earth orbit. Would a civilization on a planet...

I don't think there is a credible answer to your question, although I might be wrong somebody might be inclined to ponder more science informed sci-fi
How well would life develop on a planet with low oxygen?
>>7998403
I don't know anything about biochemistry. How possible is it that there are biological pathways that require little oxygen? For example I think the earth didn't have much oxygen in the air until photosynthesis evolved.
If your brain gets broken into atoms and then reassembled into exactly the same pattern as before. Just exactly the same as it was. Would you still have your conscious, meaning will it be like you were always you?
it's not voluntary to think 5 dimensionally, but here goes. the theseus' ship analogy explains a lot about the nature of how karma as one might call it relates nothing to the effervescerated spirit of what you know as a mass of matter. it's just atoms, ha-ha, but NO fuck NO it's way obtuse to assume things can't be the other way around just as general relativity loses its predicting power to quantum mechanics. to quantum mechanics, general relativity is just as ridiculous. qm can't explain shit even so much as realize kinematics. so why would you...

Is there any actual way that we could produce a fully working, no attachment needed and lethal light saber?
Is containing enough light within a cylindrical light saber shaped field even possible? What would I need to study to do this? I need to make a light saber. I feel seriously attached to this goal right now and for the life of me I need to make a real fucking light saber. It is my life's calling. Would there be other ways of achieving the same goal? Could plasma be contained in a magnetic field to achieve the same goal?
>>8000455
No.

why?

Solar energy seems like an obvious solution. How short of time will it be before solar energy takes over?
>>8000451
It can't deliver consistent levels of power. Nuclear is the only way.

lol the sun is nuclear u retard

Only about 20 years. Climate change is a non issue
Can a person successfully ride a bike on a treadmill? I feel like both sides have good arguments. Yes because the bike is still making the same movements as if it were covering ground. No because no matter what the bike itself is staying still and has no forward momentum to keep it going. Discuss.

Can a meme successfully ride its way up the /sci/ board? I feel like both sides have good arguments. Yes, because the meme is still hilarious and causes people to make the same arguments as if they were covering ground. No because no matter what the meme is, it is staying still and has no forward momentum to keep it going. Discuss.
>>8000432
Seeing as I can cycle up a hill extremely slowly I am going to say yes.
>>8000449
Its actually a good question, and there have been a number of experiments regarding how bicycles impart balance because the answer is not nearly as simple as the problem would appear to be.
It did get answered tho, and it actually has nothing to do with forward momentum (this should be obvious, if you think about reference frames) or more surprisingly, gyroscopic stabilisation from the wheels (they made a bike with tiny tiny wheels and you can ride it no problem).
The answer is simply that you have to...

What kind of thing is this?
Any butterfly experts on right now?
Do not touch my sci board friend it is a bee from the insect speicies do not you hurting fagg.
i am repeating do not touch the bee! it will stink you it is mechanism of defence for protect from predators
i know you are not preeed itor but do not be hurt /scie/nce user

has anyone noticed that /sci/ has been invaded by highschool level math problems?
It's been like that for 2 years already.

How is this a bad thing? Looks like this shit unlocks the universal library.
>>7999362
that's not what it shows, it shows activity
How many of you know about this hypothesis? In short, it is an imaginary library that contains all the books that have been, will be and could be written, in all the languages and all variations. The library is structured like a honeycomb, with room-sized hexagons, each hexagon has many books, and overall it contains about 10^4677×410 pages. There is an online version of this, using some complex algorithms. If we were to assume that the algorithm would generate only the pages with words of the English language, using the simplest possible vocabulary of about 20000 words, all...

So did we ever figure out if this whole gravitational wave discovery is for real or a load of bullshit yet?

it has less than 5% chance of being a coincidence.
