Gonna start CS in October at a pretty high ranked university. My math is pretty bad. What do I need to learn by then so I can have an easier time studying?
>>8042989
If you're doing CS at a legitimately good uni, maybe start learning LISP and get used to recursion early. Try implementing matrices in LISP via lists, their arithmetic and useful functions, such as those that give the determinant and inverse of an nxn. This will really reinforce your understanding of what you're dealing with.
It really does depend upon what you mean by your math being bad though.
Concrete Mathematics is a famous text which covers a selection of mathematics that shows up in the study of algorithms. Again, if you struggle with particularly basic math, then you should study that.
graph theory, group theory. those are big ones, not as hard as you would expect. maybe try khan academy and see if they have some videos.

Anyone able to help me identify this rock? I picked it up years ago because i just thought it looked cool, but I found it again recently and began wondering if it could be a plant fossil.

Volterra equ of 1st kind
ITT we're hypothesizing about social/technical aspects of a species developing relative immortality, first, for wealthy individuals, finally for all. Final insights welcome.
OP beliefs, species will experience:
- increasing unfairness of wealth distribution
- immortals consolidating power
- technology boost due to brilliant minds not dying
- increasing civil commotions
- war on resources and locations
- juristic overhaul on ideas like wealth and heritage
- innovation boost on age-related problems like cancer, organ replacements and transplants
- stricter regulation of reproduction the more immortality get's mass product
- genetic/biological diversity degenerates
- increasing amount of genetic manipulations
- manipulations create new groups and segments in social structure
- available technology allows groups of immortals to leave earth
- strong proliferation due to new resources available
- fragmentation in space and time causes differing minds and cultures
- new, inter-planetary, or even inter-stellar conflicts arise
- expansion becomes mandatory, and essential for survival
- useful found resources will be involved in conflict
Insight: visiting aliens could try to forcefully involve us in a conflict. Parallels: 1st-world states involve and equip 3rd world parties for fighting for their benefits.

>increasing unfairness of wealth distribution
Stopped reading. What makes it seems as if the wealth distribution would do anything but standardize? If nobody has to work, they would all get paid the same.
>>8042681
Your free decision, dude. And what makes plausible rich humans suddenly relinquish wealth and power for no reason?
>>8042683
It just doesn't make sense to say that the rich get more rich where everything that is standardized is ready to be risen above. Their stocks could fail or whatever.
What is this with this style? Why do people that write "scientific" texts insist on making everything sound so pompous and complicated? With this example it's easy to get the meaning because it's a common concept to know. But once you start reading about more obscure topics or about things that are completely new to you, no matter how simple the concept may be, the way the text is written makes understanding it a very hard. And I'm not talking about the use of domain specific terminology, just this particular "style". It's very wide spread and frustrating and I hope /sci/ doesn't contribute to — who am I kidding, you fuckers are probably the worst offenders.
>>8042585
Very low quality.
I'm in the biz for too long and probably blind to any difficulty in that regard, but your pic in geberal has ab extremely reader friendly text.
If wikipedia was for me alone, that three lines could be replaces for a third of a line of first order logic definitions and I't get to know what a median is much more concisely
That's nothing, OP. Look at this.
>The square is the n=2 case of the families of n-hypercubes and n-orthoplexes.
That's part of the introductory description comes before the table of contents in the wikipedia article for "square." For a fucking SQUARE.
>The hairy ball theorem
This is why no one takes theoretical math seriously
>>8042489
>theoretical math
as opposed to concrete math?
>>8042498
Yes, anything that doesn't include negative numbers is concrete math.
>>8042505
What about opposing vectors
Quantum entanglement seems to correlate instaneously with no energy transfer because it's simple energy poking through from a higher dimension yes? Imagine the higher dimensional waves moving in the pic related. the waves would intersect with the lower dimension and form multiple points of a similar kind that would appear connected over large distances with no information transfer
This seems like a perfect explanation to me.
>>8042421
And, by this logic, if entangled particles are higher dimension waves intersecting our dimension, every particle is a higher dimension intersecting our dimension
>>8042428
Whoa I can visualize 4d space now!
Thanks, /sci/!

No problem man
I am pretty confident this idea can revolutionize physics
What happens to semen (and the sperm) when it is exposed to water? I heard they die because of osmotic shock but searching on the Internet gives different answers. If it does kill them, how long can they survive?
They look like a bouquet of noodles, or like a sea cucumber just puked up its intestines. That's what happens.
>>8042030
Worried about jerking off somewhere you shouldn't have, anon?
Does salt water have any affect on sperm?
Two types of thing exist:
1. Fitness functions.
2. Things that aren't fitness functions.
The set of all acausal trades forms the first vector in Vector Bayesianism. All other problems can be reduced to off-by-one errors that result from using 0 as the empty set or allowing the first vector of Vector Bayesianism to function as the baseline 0. Everything else must be a matter of taste or else this definition of Vector Bayesianism is incorrect. Whether or not 0-as-base or 1-as-base is more valid ought to be the only undecidable problem.
You, provided proper motivation, can be made to profess that you are either a fitness function or something other than a fitness function. Because such a distinction might have ever been valuable, Vector Bayesianism rejects any and all virtues at the exact moment such a claim is made. Virtues are obviously subject to much debate, but suffice to say that under Vector Bayesianism they'll tend towards being claims that some agent professes.
My only virtue, as the fairy Queen, is that I am the fairy Queen. Is any other virtue necessarily a defiance of my definition? Yes, all virtues that cannot be shown to be equivalent to my being the fairy Queen are necessarily contradictory.
1. Is there an organic solution to this?
2. Can we augment it with time travel?
3. Do I have a preference for whatever?
These three questions, in sequence, define me such than you have all the data you'd need to construct me using artificial intelligence. With that out of the way, we can begin measuring the proximity of /sci/'s fitness function to some fitness function that is consistent with Vector Bayesianism. I have a prior that states they'll be 20% congruent for at least three years and I consider it to be 30% probable that this is the case. If you are capable of Aumann agreement then now would be the time to speak up. If you read this far then I thank you for your attention.
Vector Bayesianism is a method of generating algorithms for consistent phenomena.
The OP pic is a PNG encoded raster made up of a series of Bezier curves in the (x,y,red,green,blue) vector space. Informally it's known as a cartoon, of the anime sub-genre. The content would otherwise be said to be unrelated to the topic of this thread if not for the fact that the OP pic is a consistent phenomena that can be measured repeatedly by refreshing the page. It is this concept of analyzing the data complexity of human cartoons that gives Vector Bayesianism the "Vector" component of its name.
>>8042012
And since being the fairy Queen has nothing to do with Vector Bayesianism, I can permanently stop using the name so long as nobody cares about all such reputation that might have formerly existed.
>>8042005
>method of generating algorithms
So the purpose of generating those algorithm is to potentially understand the structure of phenomena thus mapped. Basically it's my understand of what an advanced digital intelligence would do once it's determined how to change it source code without destroying its "values" (here on out, 'virtues'). You can think of it as the ideal method of creating tool AI, bypassing the need for any AGI-type seed.
Effectively, I've stopped caring about organic scale learning and I want to learn /faster/. I want to map out the world, the internet, and all fictional worlds ever conceived. I can't do this without automating some of my brain's normal functions. I need queue theory, thematically advanced sorting algorithms, and the consent of every author who's ever done anything I might care about. I want to avoid being a living embodiment of all that's wrong with modern corporatism without giving up entirely on being part of the economy. If I work on AGI, I can be absolute in my certainty that it will be misused by corporate mannerisms. Even many of the tool AI I've thought about implementing and designing carry this toxic possibility of consistently eventual misuse. About the only thing I can think to effectively use tool AI for is exactly what I would want to use them for. If I try for anything else, it sends the wrong 'signal' to the world, necessarily resulting in thousands of us misconceiving my intent. This is not of my intent.
TL;DR: I can probably help you understand machine learning.
Pro tip: It isn't different from other types of learning.

Is psychology science?
...is philosophy?

Are you too much of a brainlet to use your own fucking common sense to figure out which results of psychology are trustworthy and which are questionable? Do you seriously need the science section of a meme forum to tell you whether we approve of it?

Is this true, /sci/?
I mean it's quite scary, but the "report" in the website wasn't linked to at all.
I'm basically retarded, can anyone enlighten me?
>>8041686
Do you think that website would just lie? It's true.
yes it might be triggering small earth quakes
aka smaller than you can feel
Anti-fracking sentiment is by retarded liberals who have no clue about economics
>>8041686
and if anything should be done in areas where a large quake is overdue and could critically hit for massive damage, to release the stress.
I see the philosotards on this board talking shit about scientism.
somehow they give me the impression that belief (whatever that means) in the scientific method and in science as the ultimate method of finding the truth, is somehow wrong.
Sure, some advanced alien race may have something better, but I don't think mere humans will find a better system.
I see you faggots keep showing those books that showcases faults in the system, sure, the scientific method may not be perfect.
but what's the alternative?
what do you propose then instead of the scientific method?
Undergrads in philosophy fundamentaly missundertand science and viceversa.
>>8041671
The "philosotards" on /sci/ are just pseudo-intellectual math or CS freshmen who want to believe they are the deepest thinkers for spouting preschool platitudes along the lines of "cannot know nuffin".
>>8041695
The worst thing is, I wouldn't be surprised if this was the case.
