What STEM field should I major in /sci/? Explain why.
Biochemistry because then you will be able to make potions that give you superpowers.
>>7863807
computer science
you'll take a variety of rigorous theoretical math courses as well as programming courses that prepare you for the real world
expect to make near $100k in most starting positions

enjoy being miserable for the rest of your life.
Do it!!!
: is division?
This is literally a system of equations.
Aka babby shit.
I already solved this for my 8 year old sister. You got this at one of those dumb escape rooms.
I told you /sci/, I told you that hoverboards are the next big thing.

Why is there a multi company and international race for this?
Normal skate boards will always be better for tricks than hoverboards so there is no appeal for the teenager demographic.
I can assure you that no adult will ever use a hoverboard to go to their job or whatever, so there is also no mass adult appeal.
At best, the only demographic I can see buying this are college students who may use it to move around campus but college students are usually tight in money and very vew will waste money...

Prove pi doesn't equal 4
>>7862534
p*i = 4 iff p = 4 and i = 1 OR p = 1 and i = 4 OR p = i = 2 or p = i = -2
>>7862534
Define the transcendental number pi := 3.14159....
Then pi != 4. QED

Because nobody spells qt4.0 instead of qt3.14
>memorize this

Why do people enjoy this field? I'm in Chemistry 101 and man is it bad. I hate memorization classes. Surely there is more than memorization in further Chemistry classes, right?
>>7862521
You shouldn't memorize shit. You're not in college to memorize. You're in college to learn, now do that.
>>7862521
This is why I hate humanities. I'm a lazy piece of shit too lazy to memorize who said what whatever years ago.
In math you just memorize a couple of rules and it's good to go.

I looked deep into my consciousness last night as I was going to sleep and I came to this conclusion.
There are only 4 ways our Universe could have come about:
>1. It and the values of the laws of physics were purposely designed
>2. It came into a stable existence out of absolute nothing
>3. The energy has always existed and has been a circularly regenerating different Universes for infinity
>4. It came into existence out of an evolutionary chain of events, leading back into realms outside of time/matter/energy/laws, that defy all logic and may need no explanation
So which is most correct?

The one making the fewest assumptions.
>>7861571
#1 assumes explanation of creator
#2 assumes "nothing" is "real"
#3 assumes infinite regression
#4 assumes infinite regression is real and infinite things you can't know
Al lot of bullshit going on on this board, let's have a serious discussion about real technology. Which of these systems do you think will be the future of spaceflight? I am behind SpaceX for two reasons 1) they have far more funding 2) their concept is more straightforward and based on existing technology. The US military is also jumping on the reusable rocket bandwagon

I'm excited about SKYLON from Reaction Engines - Their SABRE engine is a gamechanging technology that could revolutionise space travel. They are some way away from demonstrating their tech though, so in the meantime SpaceX are the most promising route to advances in Space Travel.
Blue Origin get an honorable mention too
>>7860737
Skylon looks like a good concept but it's hard to see something like that materialising in the UK. Too many questions: who is going to fund it? where is the testing going to take place? what is going to stop it being scrapped after the obvious budget overruns and failures? where is the support for this project going to come from?
I think the moment BAE systems bought into it that it was filed together with a long list of slightly promising projects that ended up in a dead end.
Maybe it is a case...

If it works does it mean the end of the scramjet? Supersonic combustion has proven to be very temperamental, the precooler solution could make it obsolete.
why do magnetic fields make patterns like pic related?
>inb4 "muh hurr durr math equations says so!"
>>7859684
syense and math :DD
magnetronical forces
>>7859684
Because there's two poles, and you see all the lines because the magnetic current or whatever it's called is going through those iron filings like electricity flowing through a metal rod.

Since any any number divided by infinity = 0 or undefined, does that mean in the infinity of time and space of the universe, that we humans = 0 or undefined?
>assuming an infinite universe
>not considering multiverse
question has too much anthropic bias
does this prove that the universe is a hologram?
but div by infinity isn't undefined, it's zero.
Whats the average day of a scientist like?
I am majoring and STEM and want to know if i'm making a wrong choice.
I ask this because I know a math major who loves math and majored in Engineering and said it was the worst thing he ever did.
Oh, and if you are wondering I am majoring as a Bio fag but any scientist telling me their day to day would be nice.
>>7858893
This is more ore less a thread for /adv/ but being a biofag can mean many different things. Since biology is such a large field you could do just about anything.
Though with a bachelors you're either going to be a:
>lab monkey
>ecology monkey
>flipping hamburgers
It just really depends to be honest.
>>7858908
I'm thinking of going ecology and evolution for no other reason because it interests me and it sounds fun.
>>7858893
I wouldn't normally do this but I have to re read so many times your post that I am forced to do this.
>Whats the average day of a scientist like?
Missed the ' in the What's.

Does /sci/ have a bias against the potential benefits of illicit drug use?
I dont really care, just dont ask for free healthcare if anything bad happens

Pick one and only one, forever.

So the million dollar question here is...
So let's say you have to find limits using only algebraic manipulation. No effective methods like applying epsilon delta or using l'Hopital are allowed.
How do you know whether the limit you arrived at using algebraic manipulation is correct? One can get different results via different algebraic manipulations. How do you know that it's time to plug in the limit and just calculate?
The only was I see a purely algebraic way of finding a limit would work if it ends with
limt_{h -> 0} const. = const.
as in the limit h to 0 of
[math] \frac {(x+h)^2-x^2} {x+h} = \frac {x^2 + 2xh +h^2 -x^2} {x+h} = 2x \frac {x+h} {x+h} =2x [/math]
In that case the solution will be unique, yes.
>>7858022
Could we perhaps work with preimages and open sets?
Dumb weeaboo
I found this in the solutions part of my textbook. Why does this even work? There's no explanation at all.
How is bringing up the derivative of cos here even relevant to finding this limit?
>>7857855
They recognized the limit as the derivative of cos(x) at x = 0. Pretty funny desu.
>>7857855
because the limit is exactly, term by term, the derivative of cos at 0. that's nice
>>7857872
But why would they write this shit like that? That's like writing that the limit equals 5^(0)-1. Illogical, and makes no sense at all, even though it's technically correct.
Is there an easy way to square this equation?
(ax^2+bx+c)? I always have to write it out and do it manually, is there a specific formula or something?
>>7857713
why dont you compute it with a, b, c and see what comes out?
>>7857717
With what? If it's the GC, i'm retarded with it, I do most of my shit with pen and paper, i use GC for Systems of Linear Equation and Basically observing graphs.
[eqn](ax^2+bx+c)^2 = a^2 x^4+2 a b x^3+2 a c x^2+b^2 x^2+2 b c x+c^2[/eqn]
Hey /sci/, can you guys come up with an algebraic expression that ends up equaling out to xy=qt3.14? Valentine's day is tomorrow and I think that'd be nice for the inside of a card. X & Y will be replaced with initials.
>>7857680
Sure anon!
1 = 3.14qt / xy
Hope this helps!
