What in the world is this /sci/!?
I pulled out off my frickin scalp & it felt like a really thick hair follicle..
It's so wierd, it feels like hedgehog spikes..
>>7948543
check to see if there are hedgehogs living in your hair
>>7948565
No srsly why am I growing miniature spikes?

A really shitty photograph.
Okay. So. Someone was trying to argue with me that we NEED philosophy and owe all of science to philosophers. People whoften sat around and pondered existence and the universe. And of course that was useful back then but with modern technology and knowledge what use do we even have for it? We don't need to figure out "why we're here" to study evolution. I think modern philosophy is really stupid and it's just a bunch of people arguing and not getting anywhere. I don't think we need philosophy today tor progress our scientific knowledge TO A POINT...

You say modern philosophy is stupid and then ask how it differs from science? You don't know the first thing about philosophy then. Your opinions on what it is, and its value are absolutely worthless.
More importantly, this is a math & sci board. Philosophy is only slightly related, and you whining about an argument is absolutely not related. Fuck off.
Fantasic response. A true intellectual. I'm asking how philosophy different from science, what use (related to science) do we need for science, not as in ethics but say to study a species evolution. Where do they become separate.

philosophy major detected, how's that neet life going?
Is this Real Analysis or Calculus?
who give a fuck
math sucks and is useless

it says calculus
what do you think anon?

Judge a book not by its cover
>he thinks PhD topics are thought up and independently chosen by the Phd student
>>7948107
Depends on the field. You're right in math, they usually don't. You need someone to take your hand and guide you (your advisor) or you'll just crash into problems which are bad / too easy / too hard.
But there are exceptions. People who have been working on something for a while or who, through recommendations or otherwise already had a topic before getting past the PhD quals might get to choose their topic.
Aside from all of this, you're a stupid insecure faggot for taking your butthurt...

If it were legal, how easy would it be to make humans see ultraviolet or infrared?
it isn't legal?
Anyway, real easy. Just have some very small computer that transforms the colors in an image such that wavelengths between 200nm and 1600 nm are compressed into 400nm to 800mn. Get some screen to put in front of your eyes, get camera('s) able to measure these wavelengths, and have fun.

Rewriting human genome is illegal basically everywhere
I'm pretty sure a whole lot of trial and error of gene splicing from other animals like bees which see UV might accomplish something
>>7947865
who talked about genetic engineering ? I thought his idea was more like :"lets build a goggle which allows us to see infrared ! :D:D"
Thorium is radioactive but it would be too hard to get a chain reaction from it to make a nuclear bomb, but what if we develop it with something else? Or work on the chain reaction to change up how it works. Liquid Fluoride Thorium= Uranium-233 produced by thorium, Or thorium reactors? The prospect of cheap, safe energy? But then it's good that we do make uranium since we use up plutonium and authorium?

What the actual fuck are you even talking about?
It makes breddy gud TIG welding electrodes.

Any ideas of how to approach this problem?

Hello /sci/
In my native language, there is oddly no difference between "calculus" and "mathematical analysis"
That is my question (yes its dumb)
What is analysis? How would you compare it to calculus? Is there significant overlap?
Pic untelated
>>7947019
Calculus is the high school version of analysis, i.e. some quick handwavy explanation of what a derivative and an integral are and then doing lots of exercises using algebraic rules of differentiation and integration. Analysis is about rigorously proving all this shit and recognizing general underlying principles.
>>7947024
Then why is it that math majors even take calculus? Shouldnt they learn about everything in calculous through analysis?
There is no difference really. Calculus is just practical application of analysis.
So in the first million digits of pi, '3391' occurs ~2.2x more often than '1067' does.
And in the next milion 1067 appears 3.1x more often than 3391
When using big numbers statistics is useless
"Look mom the first 3 numbers this function generates are prime so every next number has to be prime too"
>>7946759
Pi is not that big
>>7946759
Pi isn't big. It's less than 4 anon.

Can someone explain the point of "conservation"?
Throughout history, several species have gone extinct. You either adapt to your environment/learn to avoid your predators, or go extinct. That's how nature works.
Humans are the dominant species on the planet, and the species that are thriving are the ones that have adapted and learned to co-exist with humans, or use humans to their advantage (such as crows dropping nuts on roads and using cars to crack them so it can eat them). That is evolution at work. If a species can't adapt, then it's...

>supposed
when you got as much power over the environment as humans do, you can take the liberty to keep things alive.
why though? well, some animals are cute I guess. and they're nice to study for people who study biology and ecology and shit. keep the earth ecology interesting and rich, you know?
but yeah, if it has to happen, it's going to happen
>>7946429
>>7946419
This is stupid. But I guess if you only ever learned STEM your entire life its reasonable to think.
When you take almost any animal out of the food chain it has rippling effects throughout the entire ecosystem. Take yellowstone and its re introduction of wolves. The wolves brought the number of grazing animals to a balance, and also forced those animals to adapt by constantly moving or not grazing where they dont feel safe. As a result certain vegetation...

you are a retard, human are part of the environment, being cute is an evolutionary trait that permitted panda to survive, it's a good strategy as any other.
Well?
>>7946401
First two.
>>7946401
A to make sure the other side is an even #.
7 to make sure the other side is not a vowel.
D to make sure the other side is not an even #.
4 to make sure the other side is a vowel.
You have to turn over all of them. No way around it.
>>7946404
How does that tell you D doesn't have 2 on the other side and 4 doesn't have F?
So Vi Hart and the internet at large told me that Pi is evil blue-pilled shit that makes everything difficult and bad, so everyone should use Tau which is Pi*2, because it makes learning higher math so much easier.
Is there a KhanAcademy alternative or some math textbook that teaches with Tau?
>pic not fuckin' related but came up as image search for "Tau"
The impact that switching between Pi and Tau has on pedagogy is totally negligible. You could better spend your time on anything else, basically.
>>7946099
Pi vs. Tau is a pointless semantic quibble.
>hurr everything is so much harder if you divide this constant by two
Even if you subscribe to tau being better, at best it helps you develop your low-level intuition a bit faster. Nothing non-trivial changes.
