Suppose a CS curriculum consists of n courses, all of them mandatory. The graph G = (V, E) of prerequisites has a vertex for each course, and an edge from course u to course w if and only if u is a prerequisite for w. Give an algorithm that works directly with this graph representation, and computes the minimum number of quarters necessary to complete the curriculum. Assume that a student can take any number of courses in one quarter. The running time of your algorithm should be O(V + E). Describe in pseudocode

What happens when a hydrate is dissolved in water, i.e. in the aqueous phase? Do the waters of crystallization leave and join the waters of the solution? For example, in solution would CaCl2+2H20 -> Ca2+ + 2Cl- + 2H20 (l) ?

Differential Equations What the fuck

Hey /sci/ So I have a question which I simply do not know how to answer; it involves finding the pH of a buffer solution prepared by adding 25cm^3 of 0.5M methanoic acid (ka = 1.78x10^-4) to 10cm^3 of sodium hydroxide (1M). I really dislike asking these sort of questions here, but any info I found online wasn't too helpful and I simply do not know what exactly to do. Any assistance is greatly appreciated. Thanks in advance. inb4 'how's highschool OP?'

I'm trying to find a formula to represent graph of what happens with an even degree polynomial as the degree gets bigger. I tried to input "lim n->inf x^(2n)" into WolframAlpha but it's not giving me a graph. As the degree of the polynomial increases, the graph should look more like a rectangle without a top border (pic related). In addition, does anybody know the function for a square?

So yesterday there was a thread about tesseract, and it just blew my mind. I simply cannot grasp the concept of 4 spatial dimensions. I mean, I can grasp the concept, I get what it should be, but I have SUCH A hard time imagining it. So, I know that the shape on the left is a 2D representation of a 3D model of a 4D shape, but I don't think holding it in my hands would do anything different (I saw the Carl Segan video about tesseract) so I'd like an answer to just one question: As a 3D beings, is all we can do just understand the "shadow" of tesseract or is that just limit of my personal imagination, and everyone can totally imagine a 4D object?

Engineers at Duke University have designed a breakthrough gadget that 'harvests' background microwave radiation and converts it into electricity, with the same efficiency as solar panels.

Could humans ever change the orbit Ceres and force it into Mars?

Optics question here, but perhaps more suited for mathematicians. Pic related. You have a source of light which sends one pulse. It will propagate intially with spherical shape. But if it travels through a medium with variable index of refraction n=c/v , the sphere will be deformed. Then my question is: is it possible for this surface to (after some time) intersect itself?

I came here bearing a question. Is there anyway to find the velocity of a boat with only Power, current, voltage,weight, density and volume given? In order to find the Drag Coefficient, Reynolds number is needed thus velocity is needed.
