Watch your backs.
I'm trying to feel out a hypothetical compound growth formula for a youtube channel, to compare its growth metrics to the actual growth it sees over time, but I don't really know how to use log functions on calculators or any good online ones. Can any of you direct me to some useful information regarding those that is fairly dumbed down for people that are... lacking in math knowledge? (I got continuously hung up when shit got to the quadratic formula, for reference).
Assuming a youtube video gets 100 views its first day + 25 views every following day at base, and each youtube video uploaded increases the value by 1% (so base value for the first video would go up to 101 + 25.25, etc), what will be the average amount of views per video if one were to upload 2 videos a week for a year?
I have no idea how to go about solving this; I'm not asking for the exact answer, but a useful place to plug in the information and tinker with the formula myself.
Sorry that this is probably poorly worded, like I mentioned, I'm not great at... brain... thinky thing...

Nobody on this board actually knows how to do math, you're best bet would be asking the /g/eniuses over in the technology board.
I'm not convinced.
I claim you always have 1/3 chance of winning the car.
Well, if you're not convinced, do the experiment yourself and see what your findings are.
>>8636410
Nobody asked you for your opinion.
A thread like this pops up once a day, can you stop fucking shitposting please.
This situation has been tried and tested many many times, and each thread ends in the same explanations.
Do a computer simulation if you don't believe it and see for yourself.
It's a fucking proven theorem, get your head out of your ass.
Greetings,
Just finished my M.Sci in mathematics(22yo) and am now teaching two courses at my local university: remedial math and introduction to statistics.
Most of my remedial math students are freshman and 75% female. Many of them are incredibly attractive -more so because they're all 18 - and I would like to pursue a relationship with them. However I do not know how to cross the boundary from professor->friend->lover.
Any suggestions and advice would be greatly appreciated.
>Tl;dr how to pursue relationship with your students
Have a lot of office hours / tutoring times avaliable then find a fem-brainlet and crack jokes while tutoring
>>8636072
Also, go to common University bars and local clubs that usually have too many kids with fake IDs, chances are you'll find a student and drunk students are usually very excited to see a teacher and want to party with them
>>8636069
You sound like an autist. None of them are interested in low paid spaghettis, like you, but if you do insist on embarrassing yourself, maybe you can try offering tutoring after class, etc. if only ugly people come, cancel it. Otherwise you can move in.
Enjoy losing your job or getting kicked out of your phd program.

Who are faster at programming:
Self taugh guys
People with bachelor degrees in CS/SE
By faster I mean capable of writing an entire solution, be it a game like minecraft or some database shit, or anything non trivial.
how much time a self taugh guy vesus a guy with a bachelor would take to code something like minecraft?
>>8633579
i think it is varying. depends on what language they use , if its a good student and how much training the non bachelor had. when you have as much exp. as a bachelor prolly youre just as skilled as him/her
You failed from the outset. It isn't about speed, but thoroughness. If you just sit down and start hacking shit up the technical debt will quickly catch up to you and you'll find yourself at an impasse that you cannot overcome and have to scrap everything. Especially for a large project like a full game.
Guys with a good CS education know this, coding bootcampers don't. Now you know why the former gets hired more.

Why does maths work? I understand that it revolves around taking and expanding basic axioms. However, even from basic calculus, I gather there is a lot of symmetry and coincidence between different areas of maths, and maths and different sciences. What different arguments are there for explaining this? Where can I read more about this?
it just werks
>>8633373
Thanks.
>>8633372
The explanation, I believe, is as follows:
Math is the "fundamental" science. Physics is the application of math on observed phenomena. Chemistry is the application of physics on observed phenomena. Biology is the application of chemistry on observed phenomena.
Singapore tops latest OECD PISA global education survey, Japan, Estonia, Finland & Canada are the 4 highest performing OECD countries.

Pretty soon I'll be making very large images concerning general advice and methodology for education in stem.
They will include but are not limited to: educating those with no stem background, proper college course "tracks", textbook recommendations, etc.
The goal is to be able to take one or more of these images, and post them in threads we see here every day, month after month.
>"ANON THERE'S ALREADY A WIKI FUCK OFF"
Okay, that's correct, but that doesn't seem to cut down much on the overwhelming "help-posting". The goal would be to create something that's easily replicable in each new help thread. And hopefully people will let the thread die after that.
>"ANON IF PEOPLE CANT READ THE WIKI THEN THEY CANT BE BOTHERED TO LEARN FROM YOUR IMAGES"
I feel the wiki, while an important resource, is slightly outdated, and still requires action on part of the poster who needs help. As in they have to read it and click on links. Also a large majority of younger/new users seem to be "muh ADHD", and can't be bothered with it or flat out ignore it.
>"ANON WE SHOULDN'T CATER TO BRAINLETS"
I used to agree, and then the hundreds of help-threads a day kept deleting my b8threads and shitposting. I can't have that.
So if you would please, if you have what you consider to be useful images concerning textbooks or screenshots of past helpful posts, or hell even a copypasta that you liked, post it in this thread, and I'll try to incorporate it.
Should take like a month, we'll see.
>>8628130
Did you make this thread to defend yourself against criticism you yourself came up with?
Anon, you need a diary.
>>8628133
No, just made a less expository version a few weeks ago, and got some of these replies.
>p..plz post things
>>8628135
Ok. Anyways, this sounds good. Who cares about the wiki anyways. I am curious to see what you come up with. But make it fun. Like, add an asterisk somewhere that says *no women allowed
I have a simple question, can a human break a light bulb only with hands and if a human could, tell me how to calculate the force that you need to break it.

No that's impossible
No mere mortal could break an incredibly thin piece of glass with their hands

What are the foreseeable trans-humanist developments to take place over the next century?
Is it worth worrying about politics if in a few decades a new frontier of technology and medicine will supersede the confines of the current human condition? Or will we plateau for a while and have to keep the current human colony systems afloat until we make it to the necessary breakthroughs? That, or work through incremental changes that gradually transform society?

First all diseases carried with genes will be eradicated - ref. CRISPS/Cas9
Brain research will continue and some will do questionable experiments and "fill in" some of the cortex "grooves" to emulate Einstein's brain which had added matter where others have a groove.
next will be electronic interfacing to the brain. See "Altered Carbon" and "project Soul Catcher".
Hearing will be augmented to suppress noise better and to extend hearing range to ultrasonic frequencies
Vision will be improved to extend into near IR and into UV while protecting the retina.
"Mistakes" in human anatomy will be corrected like the positioning of the prostate gland etc.
CRISPS/Cas9 will be a cornerstone in much of this.
>>8637757
>extend hearing range to ultrasonic frequencies
What a shit idea
you'd constantly be aware of small electrical transformers constantly buzzing
>>8637936
>small electrical transformers constantly buzzing
Beyond 20 KHz??
Most transformers are at 50 or 60 Hz, location dependent. Some are at 400 Hz. CRT sweep frequency transformers are already audible and not a problem.
I tested my niece and she can easily hear 23KHz and she has no problems with this.
I used to have high frequency hearing but that is now gone. I still have advanced autism grade hearing and I am constantly aware of most things happening on the same floor as where I work. A colleague cold clearly hear even beyond that and that was just past the limit: he had to use cotton or ear defenders constantly.
You really get to appreciate good hearing when you are out doors. I get to see a lot more wildlife than most others.
Is "memetics" pseudo-science?
>Memetics is the theory of mental content based on an analogy with Darwinian evolution, originating from the popularization of Richard Dawkins' 1976 book The Selfish Gene. The meme, analogous to a gene, was conceived as a "unit of culture" (an idea, belief, pattern of behaviour, etc.) which is "hosted" in the minds of one or more individuals, and which can reproduce itself, thereby jumping from mind to mind.
https://en.wikipedia.org/wiki/Memetics
THE MEMES
I like the idea but I hate that he slapped a name on it and acted like it was his. Any biologist could have come up with that, shit aint even special somehow.
>muh monkeys
>muh ideas
>muh learning
>muh "memes"
>>8637599
I don't see how this improves upon more general concepts like a frame.
Isn't a meme just a frame that is reproduced (with error) upon interaction of some sort?

Am I wrong in saying that every conceivable simple formula has been tried and checked in trying to use complex numbers to predict the location of prime numbers on the real number line?
Because if so, then that would mean time is better spent on thinking about the problem in the context of wave equations and Herbert space rather than tricksy math identities.
>>8638025
>Herbert space
>>8638025
They exist, but they're not very good and require fine tuning.

Any good Calculus textbooks for a beginner? Going back to school next semester and I want to brush up.
c'mon my dude, that was a simple google search. I feel the urge to insult you flowing through my bones. I think your best off following the videos on Khan Academy then go on MIT OCW and take their calculus course.
>>8638008
I did do a google search, but there's a lot of varying opinions, just wanted to ask directly .
>>8637988
How comfortable are you with algebra, geometry, and trig? If the answer is not very then go back and master those. Dumbasses complain about calc being hard because they sucked at the prereqs to begin with. Don't be these people. If you are very well versed in these subjects already, then just grab Stewart's or Thomas' Calculus and work through the chapters. If you want something a bit more concrete then get Apostol (Spivak and Courant are also good but aimed more for real analysis and expect previous knowledge in calculus already).
