The continuum is a safe-space for analysts to handwave away certain subtleties on the grounds that it's "approximately correct" (this is a pretty nebulous phrase, because they never keep track of their error bounds either).

Discrete math systematically keeps track of everything, so it only seems hard in comparison.

Because using the tools we currently have available to study combinatorics requires a very good/large working memory (the average individual has a working memory of 7 elements; a high IQ individual with a good working memory might be able to juggle a few dozen elements). If you can find a way to abstract away the details, you can "simplify" it, and indeed, there exists some ways to do that, but no one has found a great oracle that allows every combinatorics problem to "smoothed" out.

more humans = more cows and sheep = more farts = more methane in the athmosphere.

>Ruminants are responsible for about 25% of the methane produced in Britain.

Climate change is fake. It's politically driven environmentalist fearmongering.
If you light fires things warm up obviously but planetary scale heating and cooling is done by the sun.

The Earth receives energy in the form of radiation from the sun, primarily at the higher end of the infra-red to near ultraviolet range
It then re-emits that energy as radiation back out into space, primarily in the infra red range
The atmosphere is more absorbent at some wavelengths and less absorbent at others

Carbon dioxide is mostly transparent at higher frequencies, but mostly opaque in the infra-red range
The primary fuel source of humans since the industrial revolution has been fossil hydrocarbons, which are molecules composed of hydrogen and carbon which have been trapped beneath the surface of the Earth for millions of years
Burning hydrocarbons produces water and carbon dioxide (and soot, if there is not enough oxygen)
By burning a large quantity of hydrocarbons, humans have increased the proportion of CO2 in the atmosphere

Because CO2 is transparent at the wavelengths of light received from the sun, but more opaque at the wavelengths of light emitted by the Earth, there is a net gain of energy into the atmosphere which leads to an overall increase in temperature
Hotter bodies emit more radiation, so eventually the Earth will heat up to the point it is emitting as much energy as it is receiving again and thermal equilibrium is reached
However, the increased thermal energy in the atmosphere and oceans is predicted to have many undesirable consequences

Various other gases, such as methane, which are produced in large quantities by human activities have similar effects to CO2

The paper is wrong, P/NP can't be proven this way.

Think so? I was thinking of aiming to reach along the lines of genetics maybe? A combination of both?

Use many presses to generate a single output.
Press it many times, say 100.

If you get more than 60 1's, interpret that batch of 100 as a 1, if it isn't more than 60 return 0.

Keep a tally each time you press the button if you get a 1 or a 0. Once your 1 tally gets to 6 or your 0 tally gets to 4, you stop and declare that the winning result.

>>9110410
actually on second thought you should be able to get the same results with just tallies of 3 for 1 and 2 for 0. So you would need a minimum of two button presses or a maximum of four button presses to get your random result. I think this is the most efficient way.

that's why I hate discrete math

A proof is a proof, faggot.

Here's a stupid piece of shit article about a math problem solved by shitty proof exhaustion. Fuck you Rao. Fuck you Hales. Lick the filthiest fucking hole you can ever find.

It's just called diffraction spikes. I guess you could call the source a point source, I don't believe there is a word that encapsulates them both nor a need for one.

I'm so bad at maths, I will rewrite math notation out into verbalized text and cross reference any confusing operators with more verbal definitions until I can understand it.

I get words. I don't "get" math like other people do and have to compensate.

Well, it's not trivial. For example, how do you start to solve oscillator equation?

males are better at teaching males
females are better at teaching females

males are better at teaching adults
females are better at teaching children

Females tend to be more inclined into teaching so in general, maybe. But in my STEM uni courses, no.

>>9109452
If anything I do the opposite.
Some times, of course.
Also, most of the times when it's a female they don't know shit and are just reading a script

>>9109277
it's more just to fuel their superiority complex, actually

Troll thread aside, I don't understand why Europeans get so worked up over the fact that Americans know both systems of measurement while they know only one.

>>9109277
capable doesn't imply that it is a good idea

you can walk just fine with a fork up your ass but why the fuck would anyone rational do that

>>9109263
Fuck no. Microwaves can superheat stuff because the shit you microwave stuff in does not have nucleation points. IE your coffee mug is so smooth that there is no place for bubbles to form. Also uniform heating

Sounds like horseshit

No collisions in rotational? The fuck? Just imagine a room full of rotating water molecules and tell me how that could happen. More so translational is easier to access then rotational and so it'll be filled quickly even if rotational energy levels are filled first.
