I'm attempting to read through Lang's Basic Mathematics book, but the way he words his problems is odd. I had to search up the first practice question online because I couldn't understand it, but figured out it was very easy when someone helped me understand the wording.

What is a good way to wrap my head around this book? Everyone keeps telling me that this is the goat of all mathematics books that go over basic algebra, but is it really?

The only reliable non-biological determinant of height is childhood nutrition.

Arctic ice is mostly gone. A bunch of coast cities around the world are submerged.

There's a small colony on Mars, and many outposts on the moons of the solar system.

Telescopes are insanely good and many earth - like planets have been found, but we can travel at 0.1c top and all of them are out of reach (this could be wrong if proxima b turns out to be inhabitable).

AGI runs the world. Humans are a small minority compared to how many conscious, intelligent artificial beings inhabit the world. Most humans are also different compared to today; aging and cancer are a thing of the past, and prosthetics and neural implants are the norm.

Religions are very popular, even more than today, with new cults being developed and prospering.

The average citizen spends 90% of his waking life in FIVR.

Some communities of "old style people" are still present around the world: just like mormons today, they use very limited technologies and AI.

?The weight of evidence currently shows that petroleum is derived from ancient biomass.[16] However, it still has to be established conclusively, which means that abiogenic alternative theories of petroleum formation cannot be dismissed.[17]

>A 2006 review article by Glasby presented arguments against the abiogenic origin of petroleum[clarification needed] on a number of counts.[1]

So basically all evidence so far suggests you're wrong but as long as there is a chance you're more willing to believe it's all part of a conspiracy against you than that you're wrong.

Sure, go ahead. Believe retarded shit. I'm not going to stop you. If anything it increases my ego knowing there are retards like you out there.

I'm looking for a periodic tables of elements that has more than usual amount of information for use in inorganic chemistry. Pic related but its for "earth science".

Such as: ion sizes, complex forming trends

You won't be able to find one table unfortunately to suit all your needs, but I'm certain you can find a great many individual tables which will serve your needs admirably.

What are the main differences between Electrical and Computer engineering?

I know EE uses a fuckton more calculus, and CMPE a fuckton more programming. But how else are they different and how are their career prospects in the far future?

Actually at any respectable place they use the same amount of calculus, in fact CE uses broader math.

They usually differ in their focus. More specialized classes and later specializations are more computer/programming/embedded systems related for CE.
>>
Bumping for this. Sci .. I want to hear your opinions.
>>
As the other person said CE is more computers/programming/embedded systems for later courses and EE has more power, EM, communications, etc.

At my university there are about 8 different specializations for EE undergrad. It is a very broad field and can lead to many different types of jobs.

For career prospects if you live in the US check bls. If you can't really decide I would choose EE as CE is just a subset of it.

Got my IQ tested and looking back at all my scores I scored at 125 for my verbal IQ. The psychiatrist that tested me said it was impressive, but I never hear anyone talking about verbal IQ when discussing intelligence quotients.

If you have a high verbal IQ what are you genuinely superior at than most people? What comes easier to you, things like public speaking or is it deeper than that? Should I look for a job that this will benefit me in?

What does it mean?

I suppose I do notice those tendencies. I love to debate and I'm thinking about applying to law school, but I might just stick with getting into the business field. Law school is just too damn expensive but with those abilities I am considering it so I could get a job that I could be skilled at

hey /sci/, question for y'all:
so we all know the debate about euclid's fifth postulate, is it right, is it wrong, is either argument even provable, etc., but non-euclidean geometry makes no sense. it's built entirely upon the plane being a disk (hyperbolic), or an infinite sphere (elliptical). a plane is defined as a flat, two-dimensional surface that extends infinitely. if a plane is 2-D and flat, how the fuck do you end up with a spherical one and convex bubble triangles? shouldn't that not be allowed to happen? doesn't that break the definition of plane?

>>8507709
that's just translations

>>8507175
Even straight lines curve in on themselves at infinity, if your measure of signed distance (displacement) is restricted to the one point compactification of the real line, instead of just the real line itself.

So think of non Euclidean geometry as what happens when your measure of displacement is based in a FINITE one point compactification of the reals. As in, one where infinity is a finite number, and any numbers beyond that are undefined because that's where it curves back around.

So yeah, a plane is still flat, it's just that flat has actually been infinitesimally curved all along, and now we're redefining the curvature of flat to not be infinitesimal.

>>
>>8507156
I know some other parents that do. They say it's basically just math worksheets. You can get similar stuff off the web easily. The only thing it seems Kumon adds to this is that it gives you an incentive to have your kid actually do the worksheets. If you are paying for it, you are more likely to follow through.

If you can download worksheets, make a schedule, and keep your kid up with that schedule, then you don't need Kumon.

Why do you guys mention particular classes as if they're the same at all universities when the courses are much harder and have more content in higher ranked universities? Calc 2 at Princeton is different to Calc 2 at some random state school.

Also there is the huge irony that whenever someone (usually a /g/ or CS person) boasts about how many people failed out of their courses, it only signals that they go to a low quality university and are surrounded by stupid people. It doesn't signal that the material was hard.

curriculums across the average state school are more or less similar on average

there's no point in mentioning what school you went to when you speak about your calc ii class unless you went to MIT or chucklefuck community college in bumfuckville

>it's another CS shitpost thread

>>8507086
That's not true though. High ranked courses are just as dumbed down as low ranked courses. The real benefit to high ranked courses is that the level of exclusivity actually means that it's really valuable to network with the people attending there.

Woe be unto the fool who goes to a prestigious university and doesn't network.
