I ve been reading alot of news recently about ai, and how an "insanely" amount of money, time and research is being put into applying it to personal cars by major brands and private investors. Why? We could be investing in space exploration/colonisation (didn't NASA design plans for this back in the 70's?) Why this stupid interest in cars, most people I know already expressed a negative reaction to the idea of a self driven car.
>Space exploration
We already have telescopes and satellites.
>Colonisation
Why would anyone want to live in a lifeless rock?
We have a lot of automation to do here on earth before we will be able to venture out.

It's not lifeless if we live on it
>study a little bit
>take the general GRE
>get above average scores, 60th percentile in math, think I can do better
>study all winter break
>retake it today
>get exact same score (pretty sure I did better on the writing this time though)
Why do I suck, /sci/?
low iq
you didnt study enough or you half-assed
>>7776468
Studies have shown that studying for the GRE does very little to affect the score.
Thoughts on Architecture, /sci/? Anyone here interested in it?
>>7776425
ive always loved it, thought i dont think i have the mindset for it
>>7776425
As a major, it's a pain in the ass. I'd rather do calculations all day instead of drawing and building paper houses. I respect Architecture majors for their willpower.
Went to FIU where they have an awesome architecture course and department.
Students get their own desks and shit, its like an actual architecture firm.
Some of these requirements though. Room mate had to build a difficult design, turn it in unscathed traveling accross campus. Then, the new assignment was to improve it without the model he built. Pretty tough to improve it off the notes and memory without the rough draft. A lot of people cant handle that amount of stress.
I really respect architects. Even though the guy graduated top of his department with reccomendations and hasnt worked in any related field 8 years later.
My calculus class starts in about a week. I wanted to get a head start on studying, but I have no idea what to study. We don't get our syllabus or textbooks until the first day of class, so I don't even know what we're going to be covering over the semester.
What are some things that will most likely be covered in a calculus 1 class? Coming from precal, what should I study up on now, and what would I expect later?

Is cancer basically nature's way of saying "fuck you, you guys weren't meant to live that long or be anything more than primitive apes"? Why hasn't an effective treatment for destroying cancerous cells without killing normal cells been found yet?
Is there any real way forward as a species other than genetic engineering and/or cybernetic enhancements?
>go to /sci/ to get away from the bandwagoners
Well fugg
Cancer exists because mutations exist because creatures have to have some way of changing themselves and reproducing and removing the old versions of themselves from the system.
>>7776264
>"fuck you, you guys weren't meant to live that long or be anything more than primitive apes"
Nature doesn't mean for anything to happen, meaning is a human fabrication.
>Why hasn't an effective treatment for destroying cancerous cells without killing normal cells been found yet?
There are a variety of promising methods. There's a difference between discovering a treatment, having it peer-reviewed, testing it on a larger scale, evaluating the effects of that treatment over the lifespan, overcoming all of the legal issues and then marketing and mass producing the treatment.
>Is there any real way forward as a species other than genetic engineering and/or cybernetic enhancements?
You are a fucking retard
Male here. 6 inches, uncut. How do I go about determining the absolute minimum volume my penis is capable of occupying? I'm not interested so much in the absolute maximum flaccidity, but the minimum volume.
Meaning, as my penis exists right now, across all possible contexts except for those that result in damage, what is its minimum volume?
The minimum volume is < the minimum volume occupied in your moms vagina.
>>7776226
Get flaccid and dip it in water, very slowly, without spilling any by the impact. The water that will spill over is equal to your penis volume

Is silicon-based life possible?
No
Sincerely,
/sci/
Yes, but its going to be stunted by the lack of variety carbon offers.
>>7776151
Why not?
Can't silicon make analogues of organic molecules like silane?
What is this thing?, /sci/.

I'm curious about a certain process. Let's say that you discovered something big in the field of physics. I don't know what, something game-changing. Maybe you figured out quantum relativity, I dunno.
As the guy who developed said theory/new law, how would you go about discussing it with your colleagues without having one of them reword your paper and claim it as their own? How do you properly protect yourself from academic theft so that you can share your ideas without an Edison walking in and snatching them up and putting his name overtop of yours?
Basically, how do you secure credit for your work if you make a ground-breaking discovery? Would it be wise to go as public as possible, such as starting up a YouTube channel and linking it to some social accounts? How would you do it?
This is just a thought experiment kinda thing, nothing real. I'm just curious how actual scientists/researchers stop leeches from stealing credit for their work.
You can't. But it's ok, since discovery for the sake of discovery is the ultimate incentive.
What makes this problem more interesting is that revolutionary theories tend to be simultaneously discovered by different people in the same era.
If you've discovered something groundbreaking, it's likely that only a few people in the world truly understand how groundbreaking it actually is, even after you explain it to them.

Hi /sci/. My prof presented this problem as part of our first week of homework. He wants us to solve it with substitution and integration by parts, but I don't think we can progress with substitution. Even if we take his suggestion for u to start with, it just derives into 1dx, which now leaves us with two dx's, one of which is under a root. Am I wrong, or does substitution just not work here?
>>7775960
Do integration by parts first and see what happens.
>>7775960
I don't think you understand substitution...
if u = x+1, you need to express du as a function of dx.
Here it's easy: du = dx
then you need to substitute the function of x in the integral with a new (and equivalent) function of u.
x^2sqrt(x+1)dx = (u-1)^2 sqrt(u) du
>>7775960youI would substitute yourself for him when it comes fucking his wife and daughter
Hello friends,
Is it appropriate to have a thread about Macro economics and discuss the mathemathical equations?
If so!
I suggest we try to get out of the liquidity trap.
This is now a centrally planned economy thread

Yes, someone can.
ITT: Childhood inspirations
Earlier I was working on this question
"How many distinct anagrams are there of the word SLEEPLESSNESS?"
The answer is [math]\frac{13!}{2!4!5!} = 1081080[/math]
since there are 13P13 (13!) possible permutations of 13 letters, and every one will have 4! repeats for reshuffling e's, of which each will have 5! repeats for reshuffling s's, and 2! repeats for l's, dividing through by this gives the answer.
However, how would you go about doing something like distinct three letter words? The first method works because every anagram uses every letter and as a result in the 13P13 permutations, there will always be the same about of each repeating anagram. However, for three letter words the word NPL will only be repeated twice, yet the word SSS for example, will be repeated 5P3 (60) times, and as such there is no trivial way to divide through to the answer.
How is it done, and can a general function be built? a function with 27 inputs, the occurence of each letter in the alphabet and the length of each distinct anagram?
>>7775690
bump
the correct number for 1 letter words is of course 5, ths number of distinct letters in the word.
also for two letter words (23) i tried
[math]\frac{13P2}{2!2!2!}[/math] but it was 3 off when i tested it by writing out every distinct two letter word
protip: just because you can put two letters together doesn't make it a word you stupid pn
>>7775834
the point of the question is that any unique ordered triple counts as a word
