I get really pissed off when people say quantum physics is unpredictable therefore random
How the hell can something be random, but the collection of that something not be?

if the universe is infinitely big, can another big bang happen somewhere else?

The universe both is and isn't infinite. The observable universe is finite and we have rough estimates as to its size. The unobservable universe (the space outside of or disconnected from our universe) is possibly infinite, but another big bang in a separate point in this space would more likely represent an entirely new universe altogether.

another big bang away of all the galaxies spiralling from the point of where our big bang happened

Well the idea is that our universe will expand until it collapses back in on itself into what scientists call the "Big Crunch" (dumb name imho) and then that will become the next Big Bang.

maybe thats how we can get parallel universe by having more than one big bang happen in the empty spaces of the same universe. i hope you guys understand my wording lol

It might not be infinitely large, just so big compared to us (and growing larger still) that we can consider it that way. And it's hard to imagine another "big bang" can happen when the original big bang came from all the matter in the universe condensed to a singularity. If the universe stops expanding and collapses back to a singularity, maybe we'll get another.

do you guys know what i i could major in in college that deals with animals, like those guys you see o documentaries talking about the animals, i love animals and would like to have a job dealing with them but idk if it would be a dumb thing to pursue because it isnt important (ex. puppetry) and if it would make enough money to live off of

What do you need to become a vetrenarian veteranian animal doctor? There's almost certainly some fields under biology if you want to study them instead?

if you want to work with animals, you'll have to learn to deal with them being aggressive, filthy, getting sick and dying in violent and horrible, painfull ways.
welcome to the animal kingdom, it's going to be a bumpy ride
(also, from experience, every single biology course in university involves disections, usually on live animals)

Studying for my exams and I came across osmosis in the kidney. Nothing special but damn am I confused. Specific I am confused about the osmotical pressure.
The hypertonic solution against a hypotonic solution. The molecules or whatever flow from hypo to hyper but why exactly? I thought that because of the higher concentration in the hypertonic solution the flow would have been towards the hypotonic solution which has a lower concentration?
I should get this because this is basic stuff but right now I feel like a retard, can anyone help me?

It's the exact same reason spicy foods taste hot. Mint is pretty much the opposite of spice. (not exactly, but close enough)

I'm gonna give you the benefit of the doubt and believe you're serious here. In that case, be more specific. Why do you want to know? Is it the effect it has on the senses? Should you be enquiring about menthol instead?
#4053 to #4052 - darealsnooki

(02/02/2015) [-]
I want to know, because it seems interesting to find out why mint is hot and cold at the same time. Why every time mint is orally present, that water feels a lot cooler. This very well could have something to do with the senses, and there is more information supporting that, of course.

I also feel like that this is an out-of-the-box type of question, and for other people who ask it, I can answer. Like "teach a man to fish"

My guess is that the cold/hot temperature sensation is a result of the anaesthetic properties of menthol. It is local, so it makes things go numb, altering the senses.

no, there isn't a way to manipulate outcome of chance, you can calculate likelyhood, but that is still a chance

We know that there is no "absolute reference frame" when measuring speed, it's relative to the observer. Right? So, to me in the car the human on the road approaches me at 80 km/t, and to him, I approach him. While we both see usself as standing still.

So my question is; if two spaceships were traveling at 0.6c c = speed of light towards each other, wouldn't they, from their reference frame see the other ship approaching faster than light? Why isn't this breaking the speed limit? I see how it logically works, but I've always been told that the speed of light can never, ever be broken in any reference frame.

You're forgetting the Lorentz transformation of velocity for relativistic speeds:

V(corrected)=(V1-V2)/(1-V1*V2/C^2)
where, in this case, V1 is .6c and V2 is -.6c

because of space compression we get that each ship would see the other at ~%88.24 the speed of light

hope this helps

isn't this what happens in forming of an enzymatic transition state by Tunneling?

I wouldn't think there'd be enzymes that can function with weird chemistry like this going on, especially that this only occurs experimentally.
#4026 to #4023 - dijonmustardgas
Reply +1
(01/29/2015) [-]
it's not the enzyme that does it. Tunneling is what happens when a substrate reacts but instead of using the full activation energy, light atoms (like protons) are able to be transferred from one molecule to another due to overlap of the vibrational functions of 2 atoms, making the reaction happen way faster than the conventional tranistion state method.
but you're probably right that it is a different principle

Anyone here good at math, specifically verifying that two functions are inverses of each other? if so I need help.
f(x)=2x-3/x+1
f-1(x)= -x-3/x-2

Are they inverses, show steps and explain please.

Yes, they are inverse functions.
This is they way they tought us:

Step 1: simply replace the x with y and the y with x

Step 2: solve for y

Best engineering major? I think I decided that I'm gonna major in engineering. My best subject at school is math and I just think engineering is great, but I don't know what kind. I would prefer job stability and high pay

whatever field you chose, get an internship as close to your field as possible. I'm 25 with a master's in mechanical after a BS in physics, specializing in materials and nanotechnology with research in grad and undergrad along the way. But no industry experience=no job. Get that experience, even if it's at minimum wage, and it'll pay off later.

Engineering disciplines all operate on similar principles, so it would be best to figure out what area you want to specialize in. Whatever you do, don't pick that area for a higher wage. Choose something you are passionate about.

For instance, I'm in school for mechanical engineering. I picked this area because I want to work with and design machinery. Mechanical is a broad field, while petroleum engineering is much more specialized.

So do a good bit of research, and try to figure out what you want to work with.

Alright, in that case, try to take math and physics courses. That background will help you when you start to study at college. If you can, try to find a job/hobby where you work with your hands. If you can start doing wood or metal work, then it will give you so good insight into how mechanics work.

Like I said, mechanical is a pretty broad field, so you will have time to look around in it to figure out what you want to specialize in.

Once you get to college, really start to look for internships. Engineers entering the workforce after graduation need on the job experience. They teach you theory in school, but you need to get practice.

Hey science board, quick stupid question!
Why are the structural formulas in biochemistry always written with positive and negative charges? I failed with googling the answer and it's now that big of a problem but I still ask myself why?
E.g. pyruvic acid is written with a CO2- and not COOH or lysine is written as NH3+ at the end.
