>If I have an accelerometer and I drop it and it undergoes freefall, the accelerometer will not read anything.
uhmm, what about gravity?

Well the aliens would be doing some serious warping of spacetime by definition so it doesn't seem that counterintuitive.

It's because the host knows the content behind the doors.

There are n doors numbered 1, 2, ... n.

You choose one.

Monty Hall then opens every door except your chosen door and one other and all opened doors had a goat behind them.

You now have the option of switching to the other unopened door.

The probability of your original choice being the winner is 1/n.
The probability of winning if you switch is (n-1)/n.

>>7671522

Right, the host will never open the door that has the goat behind it so that increases the odds that the door the host didn't pick has the goat behind it.

People tend to look down on Biology because it won't bring inmediate joy or progress from it's investigations, ecologists are the ones that suffer this more than molecular branches, because they're seen as insufferable hippies. At least that's what I've seen and experienced.

Personally I think field biologists have the coolest STEM jobs.

Also a biologist cracked the genome project in the end.

I have a lot of respect for quality researchers in the field.

Problem is that undergrad biology is seen as the easy STEM major so a lot of kids with no aptitude for science take it. Not to mention premeds.

Seriously according to that SA study there's something like 17 (seventeen) biology undergrads for every one Physics or ChemE undergrad.

It's ridiculous, so unfortunately it's the normie STEM major even if a biology major on /sci/ is probably a much higher quality student than the general perception of the major.

>>7671529
So it's a case of some sort of elitism is a way?
Meaning, that because it's the most common it's perceived as the easiest? Even though it seems like it actually IS the easiest.
But more to my second question, what does /sci/ think of PA's and RN's? From what I've seen it's still a decent amount of work, albeit a little more hands-on.

are you an 18th century boxer?

>and can not afford to sleep now-a-day

Well then you're going to die quite soon. Humans need sleep. There is no chemical substitute. And if you are sleep deprived than your "work" will suffer more than if you had worked less and slept more.

Just double major in cs and stats.

Also, that term is so broad these days... It's just a buzzword, really. It used to be that they were called statisticians.

No.

painfully.

baka desu, you aren't solving for ohm it's given

Which equation are you using for power? The most intuitive one is I^2*R, since V for the power equation means voltage across the individual resistor.

OP didn't read the question and anon didn't read the OP. /sci/ is literally the retards leading the blind. Fuck this place.

You made alot of threads about this today.
You think math will help you find a job that pays well. You think that going to college for it will land you a job automatically. In reality no. You'll never make it without a deep interest in math.

Take up a job and if you like math, study using the internet. What will separate you from the rest is ideas of applications. Like the inventor of a TV sale item. He needed to just make measurements using math for his prototype and then put it to use.

>>7671063
You should start by reading the sticky you filthy fucking weaab.

Sage, reported, called hiro.

>>7671073
First thread, actually, but it does seem to be going around a lot.

I don't know exactly what job I want to do. Payment's not so much a concern for me - it's just that everything I'm passionate about requires a lot of math to really get good with. Robotics and space travel, mostly.

>>7671076
Er, thanks. I'll take a look.

Time Is Just An Illusion

>>7671038
That's what I've been thinking about. Is time just our way of telling one thing's position in relation to something else, and not something that actually exists on its own?

>>7666334
Yes. Humans can only perceive time linearly, which is where your notion is coming from.

I believe your limit is incorrect.

cos is between 0 and 1, so the (1- cos) factor must be either 0 or positive. If it is 0, the limit shows that pi = 0, an obvious falsehood. If (1 - cos) is positive, the limit shows that pi = infinity * (positive) = infinity, which is also obviously wrong.

>>7670932
I assume you have never taken a calculus course
lim of 0 * infinity can be finite

>>7670932
there is an n as a factor of (1-cos)

OP:
your x is wrong, you have x=2sin(alpha) or x=sqrt(2-2cos^2(alpha)).

Secondly, you need to show that the perimeter of the polygon converges towards the perimeter of a circle, which is not obvious, and in fact wrong (see fractals for example)

You can, however, use the same idea with surfaces (you can easily show convergence with the squeeze theorem).

Yeah that was my old thread but not a single serious response only le memeshit

A Banach space is a normed vector space V (ask if you don't know what it is) that is complete (ie. such that every Cauchy sequence in V is convergent).
Banach spaces are interesting because we have a number of very powerful results allowing us to prove the continuity of linear maps without much effort (Banach-Steinhaus, open mapping theorem, Hahn-Banach)

>>7670906

rest calm OP, they all feel the same way.

Electromagnetism, how do they work?

>>7670972
This has been the single biggest thing inhibiting me learning about much of anything.

It doesn't matter how it's explained. It doesn't matter what I read. There's just something that doesn't quite click, because I feel like something important is missing. I've developed a very bad habit of obsessing over what makes the most base layers of the universe tick, and losing sight of how easy it is to figure out how something behaves on a higher level if you just look at it.

I'm too afraid of being wrong. So I don't even try to work from the top down, and it's hard to unlearn.

It isn't pharmacies driving this (they don't make much money on vaccines), but rather governments are pushing this. There are well known side effects on vaccines, but the government has decided to accept those consequences for the benefit those vacancies bring to society. The other stuff is ok for you to object as you will only harm yourself. The other stuff will harm others and create bigger problems.

Well if you have read studies than you should know which adjuvants are harmful and which are not. 'some' is not an answer.

since what you are getting from a doctor are not 'some' adjuvants. maybe he knows whats in the little flasks, maybe he doesnt. many just do their job.

because for the 'some' adjuvants that do help protect from a distructive sickness it is worth risking autoimmune disorders imho.

I can however not name the degree of severity in which the prevented sickness has to surpass an autoimmune disorder, for my claim to be justified.

Just know that it's better to have dead killers inside of you the first time, then living ones.

Side effects: these are from a cut sheet on the MMR vaccine.

>>7670734
Amphetamines perhaps.

Your looking for something which silences the amygdala. Cocaine seems to do it for me and most stims do it somewhat, FAAH inhibitors were tested on mice, but are pretty gay for people. Androgens also work in mysterious ways and make some people more psychopathic.
