How can humans compete with actual gorillas?

>bigger muscles
>don't need jobs for survial
>vegan
>don't even bother lifting

No wonder all those women in Japan have been going over to the gorilla and visiting the Zoo just to see the gorilla. Gorilla theory is an new theory stating that women's sexual attraction is really the gorilla due to their combination of height and frame. Gorillas have bigger frames than humans and there is no way a human male can defat a gorilla hand to hand.

>gorilla penis

Humans confirmed for being all about muh dik

I don't have any hornworms, and if one gets loose it could cause an agricultural nightmare!!
>>
>>7846046
it took me exactly 2 mins of google search to look for this :Tomato hornworms are known to eat various plants from the family Solanaceae, commonly feeding on tomato, eggplant, pepper, tobacco, moonflowers and potato. Accordingly, they are often found on defoliated tomato plants, the caterpillar clinging to the underside of a branch near the trunk. They are difficult to spot due to their green coloration. Tomato hornworms fluoresce differently from tomato leaves. Using an ultraviolet light source of 375 nm and viewed behind a blue-blocking filter (yellow or amber filter), a tomato hornworm fluoresces in bright green while a tomato leaf appears deep red/amber.[citation needed] This sharp color contrast helps gardeners locate tomato hornworms at night. They can be reduced by planting marigold flowers around these plants.
>For your information, carrots and tomatoes are roughly the same because they both contain high amounts of carotenoïds.

NASA isn´t a Spacial Organization to explore the lie "they" (the famous and rich 1% of people who runs this sad World) call "Universe", their ambition is to explore Antartic, the forgotten Continet, since they find out about "what" really is behind that intimidating ice/snow wall´s. We can think/imagine about so many possible and credible reasons for this constant lies and corrupt educational system, for exemple:
-> one reason we can´t even imagine, behind that ice walls in Antartic is a military resistance for this fake sociaty (like MATRIX);
-> or, even, a completly new civilization (1947, the first time General Byrd lead´s a expedition, more than a half of his army died in the Antartic territory), which implies that the Antartic Treated was not between Countrys, was between diferent Civilizations (with that ones we call "Alien´s").
-> finally the one reason, that for me, personally, is the real truth, we are a science experiment (can´t decide if a good one…), we live in a flat earth, we live in a dome, our creator is, probably, an advanced civilization.

At the first look it may seem strange or a joke, but if you put your brain to work, this reasons, and not conspiracy theories, makes sense if you think about the freack show sociaty that appears to be on this day´s (with poor prospects for the future, we might close our eyes or look at the part, but the END is close). We can´t even imagine what´s really going on, we online get false and ridiculous "information´s" from the news! I´m tired of this bullshit theories, I want to know what the fuck is going on around me.

All matter is composed of waves. Particles don't actually exist outside of the mathematical model. Photons, Electrons, Bosons etc do not exist as individual ball-like particles, and are a mathematical quantification of a wave-like phenomena.

Am I correct?

Discuss...

Also, with Einsteins' wave theories on gravity due to be confirmed, can we finally stop looking for the "Graviton" etc and switch to Quantum Field Theory?

The general gist is that things are not intuitive. You are trying to map something that happens at a completely different scale to something you can relate to like a wave.

The reason waves to you behave a certain way is because of lots of observation and matching waves to a certain pattern.

When you talk about things at a very small scale they don't behave along the same patterns as at bigger scales. So you can't match their actions to any known pattern you can think of.

Your entire set of logical patterns breaks down.

The problem isn't if it's a wave or particle. It's neither. The problem is your inability to adapt your "rational thinking" to a different scale where things don't behave the same at all.

Stop trying to map the actions at a small scale to the actions of things at a different scale where the rules/laws/probabilities are completely different.

There is nothing less logical about quantum mechanics, the only difference is you are used to different patterns.

consider the function 1/x for any real x. as you get really close to 0 from either side, the output of the function gets bigger and bigger.

what should the output be when x = 0? it must be bigger than all the other outputs, which cover all real numbers. so the function must be infinite there. But infinity is not a real number, so 1/0 is undefined.

They should learn how to fucking feed themselves.

They should learn how to build a waste system.

They should stop being so fucking stupid and clinging to retarded beliefs that only make their lives worse.

They should start a real fucking government and actually make it work. Not just have some Jumba Mumba who is the leader for a year and forces everyone to carry him around the place he leads on their shoulders while he praises some false god.

Yes I am mad, all of the stupid fucking idiots who demand help from first-world countries need to get off their lazy asses and do something themselves.
>>
>>7845663
Well, it isn't even this >>7845672 you see they did feed them selves at one time. However, the USA sent them food for a generation or two then removed that food. During that time, farmers stopped farming because they couldn't compete with the free food. By the 2nd generation no one who was physically able to farm knew how to farm properly. The food was cut off from the USA and everything turned to shit.

This is a common method the USA uses to completely destabilize a country or people. The last time they did it was to Mexico, who is now only recovering from it. Luckily, they were a bit more robust and stubborn, but still the Tortilla riots happened.

Because traveling through space will actually enable us to visit new worlds, rich of resources and we also escape the threat of being wiped out by a meteor one day.
And because starving is only the problem of starving people by the way.

Is there a formula to calculate the grey area shown in the picture?
I was thinking about subtracting from the area of the bigger triangle [math]A_T = \frac{r (r\tan x)}{2} = r^2 \frac{\tan x}{2}[/math] the area of the circular sector [math]A_c = r^2 \frac{\pi x}{2\pi}[/math] and the area of the smaller triangle outside the circle [math]A_t = \frac{a b }{2} = \frac{(r - r\cos x) (r\tan x - r\sin x)}{2} = r^2\frac{(1 - \cos x) (\tan x - \sin x)}{2}[/math].
So we get [math]A = A_T - A_c - A_t = r^2 \frac{\tan x}{2} - r^2 \frac{\pi x}{2\pi} - r^2\frac{(1 - \cos x) (\tan x - \sin x)}{2}[/math].
This simplifies to [math]A = \frac{r^2}{2} (\tan x - x - (1 - \cos x) (\tan x - \sin x))[/math].
Using some trigonometry we get [math]A = \frac{r^2}{2} (\tan x - x - (\tan x - \sin x - \sin x + \sin x \cos x)) = \frac{r^2}{2} (- x + 2 \sin x - \sin x \cos x) = \frac{r^2}{2} (2 \sin x - \frac{1}{2} \sin 2x - x )[/math].
So the area of the grey surface is: [math]A = \frac{r^2}{2} (2 \sin x - \frac{1}{2} \sin 2x - x)[/math]. Did I get it right? Can I simplify it even further?

Yeah I need to calculate the grey area but I don't even know if it has a name, on google I couldn't find anything.
That's an attempt I made but I don't know if that's right.

I'll repost the text using the eqn tag, maybe it will be easier to read:

I was thinking about subtracting from the area of the bigger triangle [eqn]A_T = \frac{r (r\tan x)}{2} = r^2 \frac{\tan x}{2}[/eqn] the area of the circular sector [eqn]A_c = r^2 \frac{\pi x}{2\pi}[/eqn] and the area of the smaller triangle outside the circle [eqn]A_t = \frac{a b }{2} = \frac{(r - r\cos x) (r\tan x - r\sin x)}{2} = r^2\frac{(1 - \cos x) (\tan x - \sin x)}{2}[/eqn].
So we get [eqn]A = A_T - A_c - A_t = r^2 \frac{\tan x}{2} - r^2 \frac{\pi x}{2\pi} - r^2\frac{(1 - \cos x) (\tan x - \sin x)}{2}[/eqn].
This simplifies to [eqn]A = \frac{r^2}{2} (\tan x - x - (1 - \cos x) (\tan x - \sin x))[/eqn].
Using some trigonometry we get [eqn]A = \frac{r^2}{2} (\tan x - x - (\tan x - \sin x - \sin x + \sin x \cos x)) = \frac{r^2}{2} (- x + 2 \sin x - \sin x \cos x) = \frac{r^2}{2} (2 \sin x - \frac{1}{2} \sin 2x - x )[/eqn].

If you believe in Schrödinger's Cat, then there's multiple universes existing simultaneously for all quantum events. You can say that when we observe anything, the other universes don't exist, or maybe they do.

Or you can say that there were other big bangs in higher dimensions. The big bang was possibly just a quantum fluctuation.

They are about the same that dismiss the existence of god : there is absolutely no evidence.
