I am not "alive", I am just a bunch of atoms. Life doesn't exist, it is a term that is a secondary quality.

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:

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

Is there anyone here that doesn't support string theory? Or maybe not that at least doesn't support the idea of higher dimensions 5 and upwards?

If you mixed thermite into petroleum jelly would you have super napalm?

isn't this what happens in forming of an enzymatic transition state by Tunneling?
User avatar #4023 to #4022 - nimba (01/29/2015) [-]
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 (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
User avatar #4027 to #4026 - nimba (01/30/2015) [-]
it's a level beyond me I'm afraid. It sounds similar but this new development seems like some new highly artificial phys-chem method

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

Are they inverses, show steps and explain please.
#4031 to #4012 - frikandelspeciaal (01/30/2015) [-]
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
#4034 to #4010 - quatre (01/30/2015) [-]
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.
#4024 to #4010 - theism ONLINE (01/29/2015) [-]
Software engineering has one of the highest median salaries and the largest projected job growth, if you consider it engineering.
User avatar #4016 to #4010 - phoenixforger (01/29/2015) [-]
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.
User avatar #4042 to #4016 - maxismahname (01/30/2015) [-]
I think mechanical engineering interests me most. I wanna go for that
User avatar #4043 to #4042 - phoenixforger (01/31/2015) [-]
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.

mining and oil drilling probably have the highest wages, but it depends on where you live of course
User avatar #4013 to #4010 - djequalizee (01/29/2015) [-]
If you're looking for job stability and stable pay i'd say bio engineering or civil engineering

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.
#4009 to #4007 - dijonmustardgas (01/29/2015) [-]
though for Amino Acids it's usually the zwitterion notation
#4008 to #4007 - dijonmustardgas (01/29/2015) [-]
not 100% sure, but I think thats because thats usually the way they are found in their cellular environment. Given that is is (usually) the ionic form that is most reactive

You may have some corrections to do. When she starts her journey, her top speed is in another direction, and has to combine with the river current to give a final velocity with an angle of 36.9 degrees.

SO. You will end up with a new triangle with an angle of 36.9 degrees. The adjacent will be cos(theta)*12 + 2, and the opposite will just be sin(theta)*12. Theta will be the angle that the woman has to steer the boat at.

The hypotenuse of this new triangle will be a new number, let's call it H. By using trig, we can solve for the two variables, theta and H.

H will be your overall velocity, and with it and the total distance you've already calculated (5km), you can use your kinematics equations to find the time needed for travel.

If anything is unclear, just send me a message!

I'm saying that the boat's speed (12km/h) is going to be in a direction that isn't 36.9 degrees. When you add the boat's x and y components and the river's x component, then you'll get an angle of 36.9 degrees.

well, according to Catholicism, we do (although if you use logic, you can prove that we don't)

if you believe in destiny/ fate/ whatever, we don't

if you believe in chaos theory, we do
User avatar #3987 to #3986 - tarfyki (01/28/2015) [-]
Actually, it depends on if you believe we are at the very front edge of time (which i highly doubt) so i suppose it really is possible either way

Seeing as there is an infinitesimally small chance of time being linear, i don't thing it will be too big of a problem. With multiple timelines and such

I thought reverse time travel was impossible?
User avatar #3982 to #3979 - tarfyki (01/27/2015) [-]
I don't think it would be true time travel if it was multiple universes. At that point i guess it would be inter-universal time travel
#3981 to #3979 - Rascal (01/27/2015) [-]
It may be possible but only if a multiverse exists. Going "back in time" would put you in another universe.

Say reverse time travel was possible and I went back and killed my father before I was born. I'd still exist because I only killed someone from another universe who was exactly like my father, but not my actual father.

why is this place always so dead
#3965 - cloudpawtwo ONLINE (01/25/2015) [-]
What if people in comas believed they were dead, so their own subconscious developed a 'heaven' for them, which would be similar to a never ending until they died or realized they weren't dead lucid dream?
