What job can i get with an associates in math?
associate mathematician
The maths associate's assistant
>>7994068
Literally nothing. I didn't even know that they offered associates degrees for math. That's only two years of school, so the most advanced thing you could have possibly covered is linear algebra.
Serious question. Every male seems to be the same height or taller than their dad. I am 4" taller than my dad. When will it end? Why aren't humans at least 8' tall if Napoleon was 5'8" 200 years ago?

All the tall men died in WW2 and the manlets inherited the Earth and started the height ladder over again
>Every male seems to be the same height or taller than their dad.
This is not correct.
>Why aren't humans at least 8' tall if Napoleon was 5'8" 200 years ago?
Clearly the selection pressure isn't enough to drive such a change. People also actually get to eat enough growing up nowadays so that helps.

Is there any science at all behind this cheap fearmongering ?

are you retarded?
Life will continue after us. It has survived 5 mass extinctions, what's another few to it.

Having a cozy research position with a couple postdocs under you
I see many /sci/ posters claiming that they've achieved nothing because all research is now in the hands of big corporations and million dollar equipment and that if they were born in Galileo's or Newton's time they would have come up with gravitation and calculus etc all by themselves because it's "basic stuff"
But what makes you so special? Why would you have been able to do what no-one else of Newton's time managed to do? Isn't it just another "Egg of Columbus" scenario where once someone has taught it to you it seems...

in the real world success is measured in terms of achievements.
some of the people who don't have them try to bullshit themselves and others.
how fascinating.
You're right. The posters on /sci/ who claim they could have invented calculus are failures who want to cling on to something because their self-worth is determined by how "smart" they see themselves as being. This creates a lot of cognitive dissonance when they are faced the with reality of them being failures in science (not graduating high school, college, not finishing their graduate degree, not publishing breakthroughs in their fields). They try to compensate for this by claiming they were "born in the wrong era".
Just ignore these people....

It seems troubling that some of us value having the ability to regurgitate what we're taught more than that freethinking ability...
What does /sci/ thinks of David Chalmers?

I like him. One of the few non-retarded philosophers.

Into the trash it goes
>>7997784
This guy is cool. His theories are, very, not scientific, but they are fun. His famous claim is that something about subjective experience can never be explained by underlying physical processes. He then proposes that conciousness is somehow a property of our universe. His ideas are fun to think about AND to laugh at! I also associate him with this survey of philosophers he organized:

Hey /sci/
What are some good textbooks for learning calculus, algebra and trigonometry?
I have decent math, but I want to learn it from scratch again; and generally strengthen my overall knowledge.
I'm looking for books that teach calculus, algebra and trigonometry from beginner level all the way up to advanced applications. Ideally, books with a breadth of information for each aspect with solid examples, followed by exercises and/or quizzes.
Thank you.
>>7996097
Also, if it helps, I'm doing this to complement my computer science and programming studies. A lot of it skims over math that I don't have much trouble with, but I feel like learning certain mathematic disciplines separately would really help.
>>7996097
Just use Khan Academy, Patrick JMT, plus Paul's Math Notes Lamar for extra problems.
For calculus books Larsen, Stewart are standard texts.
>>7996131
I'm not really a fan of relying entirely on YouTube/video lessons. I learn most effectively from hardcopy material, with a combination of MOOC resources.
Thanks for the standard text suggestions.
About infinity and zero undefined equations on simple algebra.
Considering x is a positive real number. Why can't we say that x / 0 = ∞. Since the bigger the divisor is, the more x will be closer to 0.
Also, why ∞ * 0 is undefined, isn't it just infinite zeros, thus resulting in a total of 0.
We can say that those two equations are not undefined, right?
>>7994240
x/0 = ∞
x = ∞ * 0
x = 0
But x is any positive real number. So you're contradicting yourself.

Khan has a video on this subject in his algebra series.
Why is psychology a meme science?
I know it is, but when asked why I think that I have a hard time explaining.

How do you cure psychological problems without psychology ?

It's not really a pseudoscience, but it desperately lacks the rigor in the other sciences (natural sciences). Additionally, very few of psych undergrads end up as researchers worthy of the title 'scientist'.

Why fund space exploration when there are more pressing issues down on earth?
> for the greater future survival of mankind
That argument is such bullshit; we won't be around to benefit from space exploration if we don't stop fucking about up there and solve the issues down here.
What is there to gain from space endeavors in their current form?
>>7995816
Why fund anything that isnt the single most immediately pressing issue facing you?
>>7995816
the greatest issues can't be solved with government spending. But technologies for military application do come out of it, ICBM etc.
>>7995826
Space exploration is the scientific pursuit with the worst cost to benefits ratio out there

Why aren't there any additive/chemical free cigarettes easily available?
Pic related wasn't honest about additives/chemicals and it's clear that the additives and chemicals are what make cigarettes so harmful to health.
>>7989707
Like any large scale commercial crop farmed on industrial scales its smothered in herbicides, pesticides and fertilizers.
You can grow your own but hard to cure properly, also need rich soil.
I wouldn't worry too much about it, no one gets out of life alive, might as well be one with the chemical industrial complex at this juncture.
>>7989707
You make a lot of weird chemicals when you burn the tobacco and the paper, and the paper is treated to burn slowly
>>7989707
That's not true about the additives being harmful. The issue is that tobacco has things like tar in it naturally that damage the lungs and cause cancer (and aren't really filtered out like they would be when you hookah). Plus you're doing a direct burn (as opposed to just heating the tobacco enough to vaporize the nicotine). This is what's harmful. Finally, it's not like tobacco has any kind of anti-cancer agent like CBDs in cannabis to offset this.
It looks like American Spirit is...

Why do hot things give off light?

molten metal
lightning

Transitioning electrons emit photons.
>>7997107
What do you mean by transitioning?
If you heat up a metal, it goes red hot and emits photons. (Correct?)
What happens if it cools back down to solid and you heat it again? Have the photons returned to the metal? Thanks
