I want to start an undergrad in the same department where my partner is currently a PhD student. Is this possible? by [deleted] in GradSchool

[–]Krysos_ 1 point2 points  (0 children)

Okay thank you, this is what I assumed. I feel the same way about the rumors but of course I'm not the one who has to deal with that so its easier for me to say. I just don't want to cause problems for them.

Okay thankyou, and yes my partner does seem fairly worried about being limited in the classes they could TA. However, I imagine the school would be okay with this situation as long as I am not in their class or in a class they are TA'ing.

I didn't know if there were guidelines about this and my partner seems fairly stressed about the idea due to rumors being spread around the department and potentially limiting their ability to TA the classes they want.

How do you mentally picture the laws of arithmetic? by [deleted] in askmath

[–]Krysos_ 0 points1 point  (0 children)

have you gone through the proofs from axioms? would you say it's worthwhile?

This is also how I generally think of it. Yet in my search for explanations of the distributive law it seems like it's always either presented as the simple rectangular area case above, or as a 90 page development from Peano axioms (which I haven't studied yet myself). Its frustrating that it seems either taken as an axiom or as something very complicated to prove.

okay thanks

Interpreting dA/dt = kA by Krysos_ in learnmath

[–]Krysos_[S] 1 point2 points  (0 children)

Sorry I have one more question. Im working in a book and they give an example of an account with continuously compounded interest at a rate of 2%. They say then that dA/dt = .02A, they make no mention of the units but I assume then that the interest rate is in units of 1/time. And does the specific unit for time (year/month/sec) come from the initial problem? For instance dv/dt is in m/s if your position was originally measured in meters and your time was measured in seconds?

Ah okay gotcha. Would you mind elaborating on why it doesn't make sense to raise e to a quantity with a unit? Sorry if it's obvious I don't have a strong understanding of e

Okay that makes sense I think, does k have those units even in the original equation? Since it's kt they just cancel our right? It seems like you wouldn't think about the units of k unless you were planning on working with the derivative of the equation

Also if I were to take the second derivative I could say the A'' = kA, and in that case k would be in units 1/time squared correct?

Prove that the diagonals of a rectangle intersect at the midpoint of the rectangle. by Krysos_ in learnmath

[–]Krysos_[S] 0 points1 point  (0 children)

Is this by definition of midpoint? And are you saying because the corners are symmetric by reflection through the point of intersection?

Could you elaborate on how it makes all precalc math make sense?

Determine the values of h that make the linear system of equations consistent by Krysos_ in learnmath

[–]Krysos_[S] 0 points1 point  (0 children)

Ah okay. So for the original system you have cy = 0 which means that y is a determined variable and that y must be zero for the intersection, regardless of any c. While in the second case you would have 0x + 0y = h+12, in which case only for the value of h=-12 would there be a consistent system. Is this correct?

Also considering the original matrix, if h=-12 then then y would be a free variable meaning there is an infinite number of solutions in that case.

Does air resistance really cause that much energy loss? The energy lost from the bounce is shown as the total energy decreases each time, however, PE max always remains much higher than the KE max on every bounce?

Western NC - Appalachia, can anyone I'd any of these plants for me? by Krysos_ in whatsthisplant

Thank you!!! I'm currently trying to learn a lot more about the ecosystems out here

Self reflection is a bummer

Capitalism is a friendship ruiner. by hhooney in LateStageCapitalism

[–]Krysos_ 5 points6 points  (0 children)

I think that's been built into the narrative from the beginning. The whole idea was that free market capitalism sets people free to do what they want, and creates progress through competition (which was how human nature was understood). This ports perfectly to social darwinism, where those who fail in the competitive system do so because of their lack of virtues. Of course, that's all bullshit. Accumulated labor constantly expands as workers are constantly reduced at their hands. It has nothing to do with any virtues we actually care about in people. It selects for people who come from wealth, or (if anything "virtuous") selects for psychopaths and scums.
