Conveniently for everyone, it turns out that dark energy is produced by subterranean parasitoid wasps.
My research is so specific that I would doxx myself if I explained what I do.
I watched some technical video the other day about a quantum guidance system and for a brief second I thought it might be a flat earther conspiracy because a handful of the field specific jargon in the beginning sounded made up.
Is that the quantum gravity detection thing? Basically a way to map the entire gravitational field of earth giving each 3D space a unique position without the need for GPS?
The specific one I was watching was just talking about dead reckoning based on the same principle, but mapping seems like it could be a natural next step for the tech.
Care to share a link to the video? A way of mapping the world without GPS sounds interesting
this is especially true in math. everybody’s chilling when it’s just calculus and linear algebra. but then it becomes about manifolds, orbifolds, presheaves, adjoints, limits, modules, homology, etc.
I’m not chilling. Second try on multivariate analysis in a week. I don’t want to fail.
(Yes I’m procrastinating by writing this comment)
that’s fair. i remember multivariate being a bit rough back in the day. i feel like a lot of the difficulty with it might be due to how many shortcuts are taken when explaining things in singlevariate analysis, since a fair number of core concepts and tools don’t translate super well into the multivariate case.
i think the worst offender is the idea of the derivative as “the slope”, since that makes it quite hard to guess what the multidimensional derivative should be, and it makes the notions of gradient and partial derivatives a bit suspect. but some of the ways they teach integration in singlevariate analysis also don’t translate super well.
i feel like with calculus a bit part of the difficulty is in building up the intuition about how things work and what things mean, but my experience has been that that’s not a huge part of calculus courses. knowing some of the history about differentials and infinitesimals can also help a bit too, since that’s how calculus was first done, and it helps to understand the notation as well.
i hope some of this helps, and feel free to ask if you have any questions about some of the concepts
It should be easy, it’s just analysis but with an added dimension, basically. How is it so hard? How is it that the more I’m “learning” for that damn math exam the less I know? Why do I need it in the first place? Why have exams at all? I know what I know, and it’s not like I’m learning anything by preparing for them. I hate exams so much, it’s so stressful.
I doubt you have the answers to that, even if you did, they wouldn’t really help. So let’s ask something useful, since you’re offering.
What the hell is a total derivative, and why is it suddenly the same as a tangential plane?
Why is the gradient just a collection of the first partial derivatives? How’s a tuple of them any useful? Apparently it’s showing the direction of steepest ascend or something? I don’t get it.

The number one thing I… eh, never mind.
