Titanium is impossibly expensive at BFS scales and does not play nice with oxygen tanks. Definitely future upgrade path even if only for elements to save mass, but no place for it in early iterations and the prototype.

>alluminium + heatshield covering half the vessel

Now the question is which will turn out lighter, cheaper, and more reusable.

I forgot to mention that our EE program is still ABET certified and our ME is ABET too and they only need calc 1/2 lol, well EE only needs calc 1/2 + one random math option, not sure what real schools require, although I'd say the math route at our school is pretty standard

Algebraic number theory and analytic number theory are two separate fourth-year courses at my university.

>>10207925
I'm in my 4th year in a 4 year undergraduate course. These are the subjects I've had
- Analysis 1 (2 semesters; sequences and series, limits of functions, continuity and uniform continuity, differentiation, integration)
- Linear algebra 2 semesters (vector spaces, bilinear forms, inner product spaces...)
- 2 semesters of programming in C (the basics)
- Intro to mathematical logic (deductive logic and the basics of ZFC)
- Geometry 1 (analytic geometry; conics, quadrics, basic spherical geometry)
- Analysis 2 (metric spaces, basics of topology and normed vector spaces, differentiation in normed vector spaces, integration on R^n, uniform convergence of sequences and series of functions, integrals etc, differentiation under the integral sign, basic fourier analysis)
- Axiomatic Euclidean geometry (a medieval course, like, literally starting with axioms and deriving all of absolute geometry from them, and at the end we consider the Playfair axiom and its negation, thus going into Euclidean geometry and hyperbolic geometry, and their differences)
- Algebra 1 (a lot of group theory)
- Discrete mathematics (it was actually just graph theory; Konig's theorem, Ramsey numbers, Kuratowski's theorem and graph planarity etc)
- Intro to computer architecture and organization (a really retarded course)
- Diff. geometry of curves and surfaces
- Intro to numerical mathematics
- Object-oriented programming (it was Java; also retarded)
- Mathematical software (it was just LaTeX... also retarded)
- Measure theory (measures, the Lebesgue integral on a measure space, L^p spaces, complex measures, the Radon-Nikodym theorem)
- 2 semesters of complex analysis (the Cauchy-Riemann equations, Cauchy integral theorem, Liouville's theorem, residue calculus, identity theorem, Morera's theorem, maximum modulus principle, Schwarz's lemma, a lot of other stuff, harmonic functions on the plane, Picard's little theorem and Picard's great theorem, Koebe's 1/4 theorem, stuff like that)

>I don't have a sob story to fall back on: no courageous overcoming of adversity. I was just lazy.
That's most people, including myself, except I realized it after undergrad and not after HS. I still ended up in graduate school and now I'm working harder than most people. Turns out, that's not too hard considering the vast majority of people are lazy and half of the ones who "aren't" are just pretending. The only problem you're going to face, if my experience is anything to go by, is that personality/attitude traits are much harder to fix than you think: you're effectively trying to change what has been ingrained in you for many years. It's never too late to change but it definitely gets increasingly more difficult the longer you put it off. Good luck.

sorry, I only do ACS style

MathGen is quite useful to browse through. Many of the terms are standard, so it helps to explore combinatorial-wise connections between different subjects, and play around with them to see if you can actually discover a connection there.

I'm going to disagree with you there. There have been a lot of ideas and methods that come from Latin America. the problem really is your too lazy too look up. In Mexico there are various companies leading the research in orthopedic instruments and internal prothesis materials. Birthcontrol was invented by a Latin American. Various medicines have been discovered by regional ethnomedical researchers, but then their findings are exported/outsourced to USA because of money. A boy from my town was hired by NASA at the age of 17 for finding a more efficient way in picking up some kind of cosmic radiation. It is not a matter of brain but funding and was is called "brain exportation" or "brain flight" in my country. Don't let your ignorance gas you up.

By the fact that in the real world proves that's wrong. Reality. How is this hard to get? Genetics. Genetics. That's what matters in the end.

My native languages are spanish and guarani
Been speaking english since I was like 5-6?
Learned portuguese in a year because of roommates.
Im doing computer science in japanese in a japanese university so im fluent in that as well (say if native level is 10 im probably 7?)
And I learned japanese sign language because i have many friends who are deaf.

I wanna keep learning languages though. I really enjoy the process of it.

>>10209290

Then you aren't fluent, dipshit.

>>10208462

>Hubbard and Hubbard

Why this?

there was such pleasure in the initial reading of the Kant Hume debate, but afterwards I've found Hegel to have the sustainable burrowing interest; where '"knowing" as a process' can take us away from the boredom of the Manichean finality of nou/phen & the vague lingering existential angst of something permanently unknowable.

>>10206165
Disagree. Plato’s writing is often some tenuous metaphysical story backed by allegories, while Aristotle tends to directly analyse and categorise things and then create overarching theories which can explain these same things, which is far more /sci/ in my opinion.

>>10206111

Yes. As far as I can tell, this is in fact the only way we can perceive at all. Our apprehension is dependent on the construction of our body, with the addition of technological extensions.

The thing-in-itself is not accessible in the sense that it requires mediation and representation for us to be privy to any form of signification thereof. It is perhaps not an apt analogy, but for the sake of illustration, consider the desktop environment on your operating system as phenomena. Things as they are, are holistically represented, and in necessary relation to the umwelt of the organism, and the qualia which exists in this mediation is not inherent to the noumenon, but a necessary product of our cognition.

>>10209259
I will admit I've yet to read Hegel correctly, partly because of how esoteric and obfuscated his ideas seem to be. This is partly excused because he apparently wrote his Phenomenology under great stress, yet it's strange he never saw fit to return to it and rewrite or clarify it during the remaining 35 or so years of his life.

>>10209323
