cognitive dissonance while studying these and related topics
porque???
>>7810717
I don't follow.
aaaand its gone
art = how we felt about the world at a given time
i think thats important
gee thanks /sci/
>>7810727
nagging feeling that the subjects weren't worth studying + nagging feeling that i was completely wrong
hope that makes sense
i guess this is just how altering your own prejudice feels
When did we start losing our instinct of having reproductive sex and needing to rely on instructions/observations to have proper sex?

What does /sci/ think of Hank Green and his Chemistry videos? I personally find that he explains it well, but his 'drunk' type of voice can get grating after awhile.
Never watched him, but he's the brother of John "Come on, be a cu ck, you privileged white fuck" Green, so I'm kind of suspicious.
>>7810484
Is he a cuck though? All of his books and movies are about the white masterrace. I'm sure he is a neo-nazi.
/sci/eg heil!

Have you watched the World History series?
It's all "Europe is bad and should be ashamed for existing".
So I'm on book ten in Euclid's Elements.
On a third apotome, would the rectangles contained by the rational line set out and the annex/whole really be medial, considering the rational lines are not commensurable in square?
So basically this question is rather esoteric, considering it IS a very unused, error-ridden portion of the Elements, however I'm simply wondering if it is REQUIRED for non-square medial areas to have sides commensurable in square only.
I'd like to get your opinion on what we are going to perfect in 3D printing in 20 years.

Good morning sir. Which position do you want me to be in today ?
oh no...
solve it
this again???
As a great man once said, "if the blue meanies are going to get me they'd better get off their asses and do something".
Just what i was looking for. Im not even going to pretend like i can solve this, but your knowledge would be great. Am i assuming correctly in thenfact that each symbol hasban assigned letter?
Not sure where to ask, /sci/inteists, but is there any way to harness energy from a change in altitude?
E.g. if a helicopter goes up to an altitude of 2000 feet and then down again and repeats, is there any way to harness some sort of energy, by placing some sort of contraption in it?
>>7810323
easy, just put a system of ropes and pulleys on it that drives a generator.
>>7810323
Yeah but you would have to harness more energy than you are consuming to generate said energy.
>>7810323
Go up, you're putting energy in.
Descend, you are releasing the energy you put in.
People complain about infinity because it can't physically exist, but neither can points or lines that have no width.
Why don't people complain about those things?

what ?
>>7810187
Ok, I accept your terms.
I have one of these things and occasionally use it to froth up some milk for my morning coffee. I've noticed that only the coldest of milk will actually whip; if I leave the container out, the closer to room temp the milk gets, the less likely it is to hold a froth.
Why?
>>7810125
Abrupt changes in temperature makes it go crazy. Same when you throw glowing red steel in a cold water container.
>>7810125
Miscibility of air is dependent on temp?
Same reason why soda is better cold.
>>7810125
I don't like frothy warm milk so physics sort of just makes way for its impossibility
Hi sci.
I was supposed to write a 1 - 2 page paper on aromatic electrophilic substitution. I totally forgot to write it, since I am a faggy retard. Now I really need some help, I know that the questions for the paper are not hard, but I am still lost.
1. I am supposed to explain, in words only, what happens when 4-Hydroxytoulen transforms into BHT for both reaction 1 and 2. So basically I need to explain the differences in each reaction.
2. The I just need to state which of the two methods are the most environment-friendly.
This is what I do understand....

Anyone?
I know this board is not for stupid question, but I am in dire need.
>>7810032
Stupidity isn't the issue. Doing your homework is.
>>7810050
Yes. I know. I have just now, wish I would have earlier, really started to organize and focus on studying. This is my first year and I have not until now really been any good at keeping important events in my head.
I will - from now on.
I've never really browsed /sci/ before, but I thought I'd ask a question here. I'm a humanities-inclined person who much prefers art, literature, history, etc. to STEM, but my grandma got me pic related for Christmas because she knew I liked the Yale Courses series, though the ones I liked were usually for literature. She remembered that I had recently displayed an interest, though a very superficial one, in physics and relativity, so she decided to get me this book. I have no plans to go into any science-type career, but something about me wants to go through...

Physics is all about applying existing knowledge (including mathematics) to explore and gain new knowledge. Appreciating and understanding interrelationships and the cause and effects are important.
My research field imploded but I got a good job sidelining in quality assurance auditing. Applying methodologies learned in Physics enabled me to do a measurable better job than my other colleagues.
>Would you say there's "something to be gotten out of" doing science and math on a personal level, even if one has no desire to apply it to their career?
You get to know how the Universe works, and it works in incredibly beautiful and strange ways, from the elementary particle physics up to living organisms. It's so much better than art or literature - remember that works of humans, like art, are constrained by our mind and creativity. Nature isn't constrained in this way, and the results are unimaginably better than...

I study math because it's fun. No other real reason.
I don't really buy into all that pretentious crap about how math is beautiful or how you get to see into the true framework of the universe.
It's just fun to learn how things work, to build theories and to solve hard problems.
That's probably a good book. Shankar is a great writer.
Assuming you know high school algebra and trigonometry all you should need to get most of introductory physics down is one-variable calculus.
Take...

If you could have any life what would it be? I want to know how my fellow /sci/entists would like to live and study. Personally I'd like to live on a large spacecraft with an AI companion, huge and well equipped labs and a library. I'd travel among space marveling at the universe and while traveling between locations, research build cool shit.
I'd like to live in the wild. Among the animals. Feasting on nuts and berries, bathing in water, studying the patterns and activities of wildlife

I'd like to live in an academic convent isolated from all the normies and research math all day.

Why is it so hard for black people to annunciate?
I have never met one that doesn't speak like a stereotype. I've only seen a couple british blacks on tv that speak clearly and without ebonics.
I am not a racist, but I'm also not very well versed in biology or physiology. Is there a fundamental physical difference that causes this?
>>7807608
Enunciate fucking retard
>>7807621
gotcha ;^)
It's the same reason why british people speak like retards, or why frogs speak like frogs. People that you interact with in early stages of your life speak with a determined accent, and you pick it while learning how to speak.
Why are overdeterminate systems of linear equations always have no solutions?
>>7806680
TMâ„¢
>>7806680
you are wrong.
x+y=0
2x+2y=0
3x+3y=0
this overdeterminate system has an infinite number of solutions.
>>7806687
It's not overderminate since the equations are linear dependent.

Isn't some guy with a shitty body going to have his head transplanted into another body some time soon in Russia?

Not really. Nobodys thinking that.

Immortality is not possible, or at least not something you can experience.
