So, I was wondering how can I calculate the total volume percentage on three liquids?
Assignment is as follows:
I need to add any amount of liquid A (Methanol 53 vol%) and liquid B (Methanol 57 vol%) to create a liquid C, which has a volume percentage of 86 and volume is 30 liters.
I hope my english is understandable enough that you understand what I'm trying to ask.
Pic related, it's the formula that you're supposed to use.
Anyone?
I'm not sure I follow, but you are mixing 53 vol% and 57 vol% methanol to create 30 liters of 86 vol% methanol? This is impossible IMO, you could only get a solution in the interval (53 vol%,57 vol%). Never less never more.

So... How do you plot this?
Is it like a function that you can type down in a plotting program?

I guess you just put the differnetial equation in, and some initial parameters and das it mane

minors and double majors are only required if your actual major is not good enough. if you are doing math or CS you don't need a 2nd degree. its a waste of time.

A complete waste of time. Double major in math and CpE/EE.

Can someone please explain to me how physics is a hard science?
We are certain now that there's energy in the vacuum of space. So as the universe expands, according to the square cube law, the amount of energy increases far above the rate of expansion. This is why in the early universe the force of gravity dominated but as we expanded the force of dark energy now dominates.
What we don't know yet is the amount of that energy per unit of vacuum, we're still trying to work that out.

There's a bit of truth in every bait, so I'll explain it to you like you're being genuine.
It's a hard science physicists don't claim to know what "dark matter" or "dark energy" is.
Some people have come up with some hypotheses that can be tested. Some of them have been shown to be false. Others remain undetermined from current observations.
Some people have come up with hypotheses that we're unable to test now, but may be able to be tested in the future. These hypotheses are naturally greeted by more skepticism from others in the field.
These are great intros to the topics:

They used to be fairly dense with information, well explained, and coherent. Now they seem to be filled with irrealavant and distracting fluff that isn't of no use to the student.
I had my cousin over for a visit today, and he had me help him with some of his trig homework. The textbook they were having him read was complete and utter garbage compared to the textbook I had that was published in 84.
Why do they give students today's such shitty textbooks? Why the hell are they still even publishing new editions of books covering basic concepts like trigonometry and calculus? it not like anything has changed between a hundred years ago and now regarding the fundamentals calc, trig, and many other areas of study.
ITT: we shit on the textbook industry
>>8455707
HEY GUYS, LET'S BUILD A CAPITALIST ECONOMIC SYSTEM IN WHICH THE MEANS OF PRODUCTION OF TEXTBOOKS ARE IN THE HANDS OF LARGE COMPANIES AND MILLIONS UPON MILLIONS OF STUDENTS ARE IN NEED OF TEXTBOOKS EACH YEAR!
GEE, I WONDER WHAT COULD POSSIBLY GO WRONG!
>>8455717
The issue isn't capitalism. The issue is the fact school is publicly funded and the free market has zero say in determining matters( such as what textbook to use) as there are no penalties in getting it wrong.

BINGO!

The argument is not monotonicly decreasing you mong.
You folks hyped for ITER or what? This will blow every single solar or other "clean" energy arguments completely out. Hell, you could probably find enough deuterium on Mars to run this thing.
It's still like 15 years away from full operation. And that's assuming no more setbacks. It has already been pushed back a lot from original estimates.
Assuming it works, it's still only a proof of concept--- that concept being a fusion reactor that puts out more energy than is put in. It would be up to its successors to "blow every other clean energy argument out". It would still be awesome.
>>8455560

ITER's goal is to be a test bed for Fusion and "energy out" Fusion. Not as an actual proto-type for a producible fusion reactor.
>>8455519
Fusion research is great, but I can't see this (or anything similar) as ever being viable as a practical energy source.
Fast neutrons make it much harder to get useful energy out, as well as making radiation shielding a nightmare. Capital cost will be astronomical (capital servicing is the primary operating cost for fission).
What problem does this solve that fission isn't a better solution for?
IMO, fusion power is only going to be viable if we can get aneutronic fusion working, and tokamaks aren't going to do that (1H+11B fusion has 1/2500 the power density of D-T, so we'd need something 2500 times larger for the same power).
Can someone explain (or prove, though not required) why two intersecting perpendicular lines diagonally across a plane with an infinitely small circle of radius r in the center does not disprove the Four Color Theorem? In the middle do they all not touch and either two sections of the four quadrants would be forced to touch along the sides, or through the center, or standing as it is in pic related where the four quadrants support the Four color theorem, the circle that is colored any color would touch one of the four quadrants?
Can you articulate in a little shorter sentences?
Also, state what you think the theorem is about.
Also
>infinitely small circle of radius r
while you shouldn't even fall for the Descartes meme of thinking it needs points to make up for lines and planes, please don't reason with infinitesimals like properties for finite things apply to them
In mathematics, the four color theorem, or the four color map theorem, states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color. Two regions are called adjacent if they share a common boundary that is not a corner, where corners are the points shared by three or more regions.[1]
