What significant scientific, medical and technological advances do you expect to see within the next 25 years?

Genetically altered people thanks to crispr (praise the fucking Lord this happened I was worried we'd start to devolve if we kept natural selection at zero for this long)

>>8589361

What do you think will be the net result of this?

Presumably the already large genetic advantages of the wealthy (those genetic advantages being a major cause of their wealth) will become dramatically more significant; and the genetically inferior poor (both in global, absolute terms; i.e. Africa and South Asia, and in relative terms within developed countries) will become a sort of permanent underclass with no prospects for improvement - will they die out naturally? Will there be some sort of confrontation / genocide?

Or will they be 'gifted' genetically improved offspring?

Though, I don't quite know why you'd want to go with the latter option. Wouldn't it be preferable to have a much lower world population (say, in the low hundreds of millions at most, with all people being genetically enhanced) with practically all labour being automated than to have anything like the number of people we have today?

What are your thoughts on Westpoint? Not the military aspect, but the learning aspect and the career possibilities that it has. I'm curious to see what everyone thinks.

Obviously you would want to look around for ex WP grads and see where they are now to judge the school.

Their compsci courses is like a degree in software exploitation, malware reverse engineering, breaking poor crypto engineering, they always win the various "cyber team" challenges.

This is what you get when organized crime is allowed to run rampant, they control the quality of desks sold.
How do you think they were able to afford their nice suits? I can tell you it wasn't from providing a quality desk at the quality price they sold them for.

People have been digging holes for thousands of years, and impressively enough you're the very first person ever in history to ask "how deep can we go?"

It's not as if there's an entire industry dedicated to this very issue.

Wanting to learn more about the Riemann hypothesis out of interest, and thinking about buying pic related book to do so.
Anybody here who's read this have any opinions or other books they'd recommend?

>>8589145
this looks like shit

to learn about the Riemann Hypothesis you need to learn linear algebra, then some real analysis, then some complex analysis. also some algebra, then some number theory.

if you don't want that then you don't really give a fuck about the riemann hypothesis

>>8589145
It's a very good pop-math book. Recommended!
>>
>>8589145

Do not listen to this guy >>8589156 OP. His post is an exception to the rule of "fpbp", since his language tacitly admits that he has not actually read the book (this ///looks/// like shit), whereas I have. This guy is right >>8589179 .

Your pic related is a serviceable treatment of the Riemann hypothesis and its history for a general reader, which also doens't bog down too hard in "wow xD" pop-sci memery. Derbyshire is in fact pretty good mathematical writer for a general audience, and if you like this book, I would go a step further and recommend that you also try his /Unknown Quantity/, which is a history of algebra.

Nevertheless, it is true that the book is not a technical or properly mathematical one, which is why /sci/ users are automatically skeptical. For that, you'd want the Edwards dover book, which I don't recommend to you as it sounds to be out of your depth. This is where the fp starts to make sense - you need a foundation first. But reading your pic related is a perfectly fine way to start.

An example of a BAD popsci book about RH is "The Riemann Hypothesis", by Karl Sabbagh. Sabbagh is a jack-of-all-trades who tried a book about RH once, and is not himself a trained mathematician. Thus, in the preparation of his book (and final publication), Sabbath made /at least/ five basic arithmetic errors in his crap book that I can recall identifying while a teenager.

So I know R is the king of programming languages for statistics, but is there any good reason to learn python?

I'm learning it anyways just because I'd like to know how to program things besides statistical models, but if it could help me there too, that'd be cool.

>>8589056
it does
python is a very easy language with a ridiculous amount of packages written for it
scientists and devs use it because it's so simple and powerful, even if it's slow
so sure, learn it, but you probably want to have a purpose in mind. in any case, ocw.mit.edu 6.00SC

This. Scipy, numpy, etc. There's no real reason to learn and use something proprietary like matlab or mathematica, for the most of us.

Read this: http://www.people.vcu.edu/~rhammack/BookOfProof/

Then go on libgen.io and get Mathematical Analysis, 2nd edition by Tom Apostol. It will teach you rigorous calculus from the ground up including fairly advanced differential/multi variable calc, but he will fill in the details in the more difficult proofs It's actually readable too, designed for moving from elementary calculus to an introductory careful theoretical treatment exposing you to advanced calculus by the end of the book. It's the single greatest self-contained calc book ever written.

I have about 3 complete days to dedicate to it with little distraction. What is the quickest way to learn Linear Algebra? What online or textbook sources should I use? I just got my hands on the 'No BS Guide to Linear Algebra'.

I want to get the most bang for my buck with my time. Should I go with Khan Academy, Gilbert Strang videos? I have limited time and want to make sure I use it wisely.

Linear Algebra Done Right by Axler

There is a crash course version without any proofs so you won't exactly learn anything http://linear.axler.net/LinearAbridged.pdf
>>
>>8588854
Since you have to ask this question instead of taking the initiative on your own, I would say the quickest way for >(you), a big guy, to learn Linear Algebra is to go to class, take notes, do the homework exercises, and study for the quizzes and exams.
>>
>>8588878
I am not taking Linear Algebra next semester, I am doing it out of pure interest.

>>8588877
Thanks, I want to see proofs. Is there a version with that included? Is it better to understand Linear Algebra from a computational point, then theoretical, or is it better to learn theoretical then practical or both at the same time?
