Is math a science?
You have five seconds to convince me that I should give TWO shits about gourp theory.
You can't even apply it in the real world.
Where is God located /sci/ ?
How do you choose a good subject for your PhD /sci/? I'm currently stuck between two options and my PI is supportive of whatever I decide to go with.
>Have an idea that can allow me to achieve what I've wanted to work on for years
>Has potential to be truly groundbreaking
>Very hard research, may take quite a few years with no guarantee of success
>Some essential methodological problems may mean it's impossible

go with option 2
dont make shit harder on yourself for no reason. you aren't going to revolutionize the field during grad school. just get it done and you can do your dream projects after you graduate and have a nice research career that actually pays
That is a really good point, but I'm afraid I will eventually lose my motivation if I give up on my dreams now when they may be within my grasp. This PhD thing takes a lot of years.
If a 0.020M solution exhibits 55%T at some wavelength what will be the % Transmittance for a 0.010M solution of the same substance?
Is this acceptable or is there a better way to solve this?
I don't have the brain power to do it any differently than this but it might agree with your answer.
Is 2 the same thing as the sum 1+1?
No, 2 is an element of Int, the set of base 10 integers
1+1 is an element of Expr, the set of all expressions
To know more about how these objects are different see Wildberger's videos.

What was around 13.81 billion years ago /sci/?
When did you realize that being infinite means being bordered by nothingness?
why dont you ever see x-axis of imaginary plane and y-axis of imaginary plane?
and area of a circle radius i would be
A = pi*i^2 = -pi
how can the universe be flat if space is 3d?
Think of a comic book. The book's pages are flat, even if you rip them in half. When you turn the next page, you are essentially determining the time rate of each event. The universe is essentially a different slide each and every time a Planck Length passes (smallest unit of time). If it were curved, the universe would be "curved" inwards as if you were pushing on a trampoline from the bottom. Things would rush faster outwards and would appear as if they were moving faster than the center.

Let's see it /sci/ :^)
can someone explain to me the difference between voltage and voltage drop, especially within the context of pic related
Voltage is always in reference to something.
That pic appears to be voltage across a resistor, current thought a resistor, and power lost through a resistor, all with resitance R ohms.
Are these creatures conclusive evidence for the theory of evolution (be it natural selection or otherwise)?
Can they mate with each other?
There is no proof that an offspring could not mate with it's ancestors or "cousins" in fact I can mate with any female human that is not sterile. (We're assuming that the human is not too old or too young for reproduction.)

Why do all calculus professors have such an enormous hard-on for arctan?
According to my calc 2 professor, it's because all of the other calc professors have an enormous hardon for it. In his words, "you're going to be seeing it a lot, so it's best to get comfortable with it now".

Why is medicine considered a science?
So I was on a lecture the other day and someone talked about properties of cancer cells compared to regular cells. From what I understood, the problem with cancer is that
1. The cells grow in bunches and spread to unwanted places.
2. The cells don't stop splitting, making it harder to destroy them.
So, I had an idea at that time that I wanted to share with you guys:
Is it possible for scientists to biologicaly design cells that use the 2nd cancer property that I listed, but without doing the 1st? Can we make use of this to create limbs and internal organs...

>when you're stuck on a mathematical proof and you know deep down that this makes you a brainlet but you lie to yourself and say that this doesn't count because of a particular reason
Can someone guide me on where to start with these kinds of limits ,tried simplifying it and I've got 0 but thats wrong .
From a mathematical perspective and assuming an elastic collision, you can write down the equations of conservation of energy and momentum, plug in the speed of the first ball after the collision as zero, and get the result m1=m2.
Are all calculus professors bunch of sadists?
My professor just announced that the calc exam next week will have 59 questions and I'm drinking vodka because I can't handle the thought of taking that shit

Is there anything you wish was implemented more in physics simulators?
The problem is that good physicists are rarely good programmers, so there's a gap that's yet to be bridged.
It'd take a lot of physics knowledge to implement memoization as well as Golly cellular automata did for general physics.
I'm an engine programmer, and I'm wondering what magical maths I could be missing out on, memoization does appeal to me a lot since it means linear increases of computing power allow me to do exponential amounts of simulation.
Here's one thing in particular I was wondering: Can I for purposes of efficiency lump an indefinite amount of objects with gravity together as one single gravity emitting object, as long as nothing else is in the bounds of that group of objects?
How can a FUCKING PLANET be made up entirely of gas? How can a planet with 11 times the volume of Earth stay as one thing if it is made up entirely of gas? Like what the fuck? Wouldn't the gas just dissipate away to outer space?
Why can't we construct our powerplants within enormous lead hangers to contain and mitigate the effects of a nuclear meltdown?
Do they HAVE to be exposed to the environment? Can we built them underground so that fallout can't spread?
>Why can't we construct our powerplants within enormous lead hangers to contain and mitigate the effects of a nuclear meltdown?
We do. They're built out of concrete, but otherwise that's what the containment building is.
>inb4 MRI scans reading brain activity
No. I meant actually reading your minds, your inner voice, your deepest, darkest secrets, the secrets that even your mum doesn't know about, the secrets that you yourself don't know about because its hidden so deep inside your subconscious
How can I lead a healthier lifestyle /sci/. Based on my previous eating habits, I may have had some significant exposure to Xenoestrogens and based on some research, they do have unintended effects and are stored within your body fat. Also, I have heard from different sources that bread converts into sugar when metabolized within the digestive tract so that is something as well.
