When I was younger I had good vision.
I started looking at a computer monitor 16 hours a day and a after a few years I developed the need for glasses if I wanted to look at anything farther than a computer monitor away.
I just tried wearing my glasses and it seems that even looking at my computer monitor things appear slightly less blurry.
Does anyone know if wearing my glasses in this way will fuck up my vision even more?
>>7792515
No, faggot. Spending 16 hours a day on 4chan is what's fucking up your vision.
Dumbass.
Was your monitor a CRT or an LCD? I think LCDs screw less with vision than CRTs from what I've heard.

Jeranism believes that maths does not describe reality.
What do the brilliant people of /sci/ think of this notion?
What is their argument ?

Math is shit tier

It's factually incorrect.

UNSOLVABLE RIDDLE TIME:
You find a jacket you want to buy for 97 dollars, but you are broke. So you borrow 50 bucks from your dad and 50 bucks from your mom. 50 + 50 = 100
You buy the shirt and get 3$ in change. Deciding to pay your parents back 1$ each right away you have one dollar left yourself.
Now you owe your mom and dad each 49$
49 + 49 = 98, + your dollar = 99$
Where the f did the last dollar go ?
The last dollar was added for no reason to get 99, when it should have been subtracted to get 97, the actual cost of the shirt that you now owe 97 dollars for buying.
>>7789500
>You start with $0
You get $100 but owe $100
You spend $97
You now have $3 but owe $100
You give $2
You now have $1 but owe $98
which in total makes your net worth -$97 + $97 shirt = $0
You actually owe each mom and dad $49.5 (half of the $99. Grab some poker chips or coins and try it.
Math is more about visualization than memorization. If you have no imagination, you'll never do well in Math.
is knowing how to compute antiderivatives actually useful? i think it's a waste of time for most people. after taking the integration class you only need to know how to take a few antiderivatives that appear in some exercises. wouldn't it be better to teach numerical methods of integration instead of teaching antiderivatives?
>>7793504
Why would you need to explicitly compute integrals at all? Integrals are only useful to prove some theorems in cohomology, and there you don't compute them but only show their existence.
In many practical situations it suffices to have numerical estimates, but goddamnit if you learned how differentiation works you can damn well learn how to do it backward. Furthermore numerical estimates don't give you neat formulas when those are available, but the pen and paper way does.

Why everything other than math seems like politicized garbage that is merely rehearsed as anecdotal truth. Yet, that's what comes about when the public is nurse on science fictions and news stories about what's going on over in Endor. Math is the only place where a person can explore the philosophy of thought and apply it to the substance. People should look at scientist and media outlet as liars, not peddlers of truth.

Hello, has anyone read pic related?
Is Darwin arguing the existence of certain body parts might be favorable to the migration of species?
For instance, wings. Is this true? Do we see more varieties and species of birds because of the large domain of territory they cover and inhabit, in addition to the decreased predators due the evolutionary advantage of wings?
>>7792665
Why would you read this outdated crap instead of a modern biology textbook?
i've read a few pages of it. the way it's written is pretty intense from what i remember. his topographical aspect was more akin to how migration was favorable for the species in a given context, although his understanding what was favorable could be questioned.

Yes, you are a retard.
Why wouldn't you read something like The Origin of Species, its influence is spread throughout the 20th century.

how do i get into robotics?
can you do anything useful without a relevant degree in robotics but knowledge of coding?
>>7793313
Pretty sure there are robotics jobs in the private sector but its mostly menial wageslave work.
You'll probably work in either maintenance, debugging, software dev, or just button-pushing in a factory that uses robots to do all the work.
But if you want to get in on the real action, you need to enroll in a well known robotics research institute

is this good practice or are there better methods for low cost?

Sand filters remove particulate matter but not bacterias and toxins. There's large scale(reserviour) purifications methods that uses micro-organisms for water treatement but I'm rather skeptical that this vat would do that as opposed to just being a sand filter.
Guys I got one question for you.
Assume a world where there live only 12 men and 30 women.
10 of those guys slept with one women.
the two others slept with 10 women (each)
So would you say on average that men have more sex than women? I´m confussed.
Read an articel that women have on average more sexual partners than men, but don´t get it how this is possible. Thx guys
>>7793286
>average more sexual partners
So one woman fucks a larger number of men at least once each, on average, than one man fucks a number of women at least once each.
That said, a man could fuck a few women a lot (5x26), then settle down, and a woman could fuck a lot of men (49) once each, one 26 times, then settle down. 130 for man in 5, 75 in 50 for woman.
Once settled down, their sex would [except for cheating and le :^) cuckoldry] grow equally.
In theory, women...

Think of 3 people. One girl, 2 boys. The girl fucks both boys.
Now the girl has had sex twice and each boy has had sex once.
Now the average number of partners for the woman is 2 and for men it is 1.
Scale that up to like 7 billion. Capeesh?
>>7793286
Maybe I'm retarded, but it's fucking obvious they have to be lying on the survey or the survey sample is too small. It should always be 50:50
Whenever you add a new sexual partner to set of unique sexual partners for one gender, logically you have to add to the other because that pair hasn't slept with each other yet.
Suppose you have 10 men and 10 women (so 50:50 split approximate like the real world)
Let's number each sex 1 to 10

All the sensible people already knew there were no ayylmaos in KIC. its just the /x/tards around posted pop-sci links that try so hard to make it look like aliens with zero scientific reasoning.

Hey /sci/ I honesty have a legit question. It might have a simple answer, but anyhow.
>what space, does the Universe occupy? You could answer with space, but the next question would be.
But that would lead to more questions!
>>7792906
Theres no way of knowing if the universe occupies any space. Your question is based on an unproven assumption
there are no types of space retard. theres just THE space that the universe sits in.
>>7792907
Anon I was just thinking, I wasn't trying to make assumptions. That's why I'm asking you guys.
It's just mind blowing to think that the "universe" or infinity, was somehow contained inside space!
What would happen if an organization put something into LEO in the ionosphere and keep it in geosynchronous orbit with a receiver to beam a laser to the location for wireless power transmission? Could an optical tether be built between the two that would allow for high-efficiency energy transfer?
The energy it would be capable of producing would rely on its surface area relative to its tangential velocity. Cost would be whatever unit of cabling versus budget of making it micrometeor resistant.
