chords represent complex waveforms that don't normally happen in nature without coincident non-harmonic combination of frequencies. in other words, chords are a very human creation. their fourier transforms break down as a sum of nearby fundamentals and overtone frequencies that most natural processes do not exhibit

Answer this question honestly:

If someone took away all the parts of you that are not associated with

>someone elses opinion
>everything about me that feels contrived
>wishing I was better / more successful like other people

would there be enough things left to recognize you?

Does it scare you that you know how short that list is?

You're smart enough to know you're pathetic and that's why it's so bad.
>if that's true then why doesn't that make it better

Because that's only the first wall. You might've toyed with the idea that you're pathetic but you've never been able to pin down quite why. Maybe it's because you're not. OR maybe it's because you're so fucking afraid to admit that - to yourself of all people - that you're more willing to wallow in mediocrity then actually attempt to pursue something and overcome your problems.

ADMIT that you'd rather look like someone who is good at math and physics than BE someone who is ACTUALLY GOOD at math an physics. It's just TOO FUCKING EASY to half understand something and then shove all the buzzwords into a couple sentences and tell undergrads to get fucked than it is to fucking DO YOUR WORK because you're afraid of trying too hard and still not getting what you want.

I've got something going on.
My little brother is in middle school. He's got advanced science and he needs to do a project for the school. He wants to use one of my giant rabbits as part of the project and i told him that i didn't care but he needed to take care of it while he was doing the project.

He keeps trying to ask me for ideas for a good project because i was always the favorite of my parents who used to put me up at every opportunity they got. They would praise me and my good grades every day at dinner and it always left him feeling sad.

I don't want to let him down. I want to be a good brother to him. I need a good project idea that utilizes giant rabbits so he can feel good about stuff he does for once.

The plants that require pollination evolved quite recently. Also there are very few plants that necessarily require pollination (for example, mankind would be just fine without pollinators, we just might have expensive melons and kiwifruit afterwards though).

Animals did not produce the CO2 that's in the atmosphere. Animals don't produce it at all in fact. They get their carbon from the plants that they eat that eventually get the carbon from the atmosphere (google photosynthesis and carbon cycle). The atmosphere was full of CO2 when the Earth was young.

Plants are not the only thing that animals eat. They can eat fungus and bacteria too (depends on the animal of course). Plants did however evolve before animals did so no problem here either.

There's this notion today that the ungodly amount of radiation were exposed to today is "harmless"

When having to go trough stuff like airport scanner they say thing like "it's less than an x-ray".

but pregnant women can't have x-rays so it has SOME effects.

1)Doesnt the fact that its forbidden for pregnant mean that all radiation sources in the world should be forbidden. Even if the risk increase is 0.00000000000001%, why would i support it for something that doesnt benefit me. In the case of an x-ray a doctor can determine if its worth it and you can decide, but if you live near a power plant you get the rads like it or not. How is this fair?

2)Wouldn't it make sense to have pregnant women locked away in basements in faraday cages in the middel of the country so that rad exposure to their sensible babies is minimal?

QM and QFT is in some sense even more deterministic than classical mechanics. One of the assumptions in QM/QFT is the existence of the propergator/time evolution operator that ensures that any wave function will evolve uniquely. This is not the case with classical mechanics, see for instance Norton's dome (a system of classical mechanics with an infinite amount of solutions).

hey man, dont beat yourelf up if you didnt get it by yourself! its just some shit ass binary puzzle.

So each half circle should represent a power of two. Writing all four number in left in their binary representation ( as sum of different powers of two) should help you find out what each half circle means.

The two equations on the right are actually obsolete as you dont need them to solve the problem.

The only values you cant find are 8 and 2, but you dont need them separately and you know how they look summed up because of 14.

>> No.10904386

This is a bad puzzle, because the solution does not make full use of the evidence.
It looks as if any ring has three states: Top, bottom, and full.
Naturally, someone would try to create a complex system from these three-state rings that generates the numbers shown.
However, the puzzle tricks the player by having the "three state rings" actually be a pair of two-state semicircles.

This kind of trick is just bad puzzlemaking because it means the actual solution is much more simple than the apparent solution, but the only people who will figure out the actual solution are those who make an unreasonable (yet correct) assumption about the nature of the puzzle.
