> and why the obsession with classifying human/environment interaction as unnatural?

What are you stupid? Becaue if "unnatural" is to have any meaning whatsoever its "things humans do"

>>8433594
But that's just it, nothing about humans is unnatural.

Bare in mind scientific are unironically defining 'natural' as an arbitrary point in history. I.e. everything before was natural and all change after is unnatural or anthropogenic.

Nonsense, the difference is in self awareness. A lion can not recognize it will run out of Gazelles to eat if it consumes more than they reproduce

1.7 Definition: Suppose S is an ordered set, and [math]E \subset S[/math]. If there exists a [math]\beta \subset S[/math] such that [math]x \leq \beta[/math] for every [math]x \in E[/math], we say that E is bounded above, and call [math]\beta[/math] an upper bound of E.

Just testing.

1.8 Definition: Suppose S is an ordered set, [math]E \subset S[/math] and [math]E[/math] is bounded above. Suppose there exists an [math]\alpha \in S[/math] with the following properties:

(i) [math]\alpha[/math] is an upper bound of E.
(ii) If [math]\gamma < \alpha[/math] then [math]\gamma[/math] is not an upper bound of E.

Then [math]\alpha[/math] is called the least upper bound of [math]E[/math] or supremum.
We write: [math]\alpha = \sup E[/math]

The greatest lower bound, or infimum, of a set which is bounded below is defined in the same manner and written as:
[math]\alpha = \inf E[/math]

1.10 Definition: An ordered set [math]S[/math] is said to have the least-upper-bound property if the following is true:
If [math]E \subset S[/math], [math]E[/math] is not empty, and [math]E[/math] is bounded above, then [math]\sup E[/math] exists in [math]S[/math]

Wow dude. Nobody in the history of the universe had thought of this before. You are a literal Einstein with unmatched creativity.

Nice thinking I like this idea

>>8433300
And yet a professor at my university told me that this idea was inconclusively explored once, by select physicists, about 20 years ago...

arithemtic
and then functional analysis

something like this

sqrt(17/2)
sqrt(34/4)
sqrt(34)/sqrt(4)
sqrt(34)/2

sqrt(17/2)

= sqrt(17) / sqrt(2)

[sqrt(17) / sqrt(2)] * [sqrt(2) / sqrt(2)]

= [sqrt(17) * sqrt(2)] / 2

= sqrt(17 * 2) / 2

= sqrt(34) / 2

I thought I'd be happy to know this, but now I'm just depressed I couldn't figure this out.

Thanks, guys.

Yes. Because it is unlikely that a non-human would even know what the fuck it means.

At first I though it would be another stupid meme about photosynthesis and CO2, but this is interesting. Was it ever researched ?

In some planets, the trees gain sentience, and live happily in harmony.

The silence is because humanity is an aberration and all other planets are content within themselves.

Well I have found this blog post, but no scholarly articles.

kek

You don't need a PHD. Just walk up to your future employer, look him square in the eye, and give him a firm handshake.

>>8432300
You misspelled blowjob.

>>8432264
But in all seriousness, you're an idiot.

>he thinks having lot's of money correlates with high intelligence
Lemme guess, you measure the world's worth by the financial worth? In reality, most really smart people are working away at real shit and earning decent money but not wasting time with business and popsci.

>>8432243
No, because the cat has no consciousness.

>>8432243
Have you actually read up on the topic? It's an example of superpositions. A cat doesn't interact with an unstable isotope

>>8432243
You missed the point. And most pop-sci that brings it up also misses the point, so I guess it is forgivable. The point Schrodinger was making is this: superpositions are stupid because they let stupid shit like my cat thought experiment happen on macroscopic scales. Luckily for quantum mechanics, Bohr came along and went "No it doesn't! Superposition states generally off at a rate proportional to the size of the system and so macroscopic objects can't be in a superposition state for any meaningful length of time!"

[This, of course, ignores some actual macroscopic states, like topological liquids and superfluids/superconducting states, but these are special circumstances that manage to get around the "general" rules]

>>8432054
absolute values are dumb, just remove it and solve it normally

>>8432084
I don't think it works like that, aren't you supposed to have more than one solution?

>>8432054
Solve it using |x| = x and |x| = -x

I fucking love Python. Clear syntax and powerful!

public static void main String(args[])
System.out.println("Java is gay")

or...

print("Python FTW")

If it weren't for enterprise bullshit and Android, that horrific language could just die in peace

>(also what's with the sin(pi) not being equal to zero?! pic related)

floating point, nigga. like 0.1 + 0.2 = .30000000000000001

scipy or numpy? Neither, MATLAB!

>architecture

Pick one.

>>8431792
Only if you go to top 5 schools.

Other then that, no.

Also, I would recommend studying civil engineering for undergrad and architecture for masters

My dad is an architect and throughout my lifetime he's subtly implied that architecture should be your last career choice if you want a satisfying job and no stress.

Why is OP such a faggot and why won't he stop posting shit threads?

>>8431783
Because assholes like you think STEM is like the only thing that matters in the world.

Let people study whatever they like and stop being a pretentious cunt.

Because being pseudo-intellectual is fun. I used to be a STEM sperg but due to my high intelligence I got bored and dropped out.
