There it is, the forced 10 second meme.

I'm not sure if this is completely /sci/ or not. I don't consider management science to be worthwhile but I think this is interesting to think about.

If Chinese people are made to work in an extremely hard working way (their Gaokao end of high school exams require crushingly high amounts of study that we'd consider child abuse and make the SAT / A levels look easy as shit), and there are so many of them, then why don't they have a monopoly on... anything? Scientific or mathematical achievement, artistic creations, businesses: They're not even a fucking footnote!

What's going on?? Is this proof that hard work is overrated?

I'm not referring at all to people of Chinese ethnicity who grew up outside of China.

Chinese people like other Asians simply don't care about discovery. They prefer to use what humanity knows now and apply it to satisfying their technological needs and that's pretty much it.

It's all about memorization. I used to be very bad at it, but then I learned what the method of Loci and spaced repetition are.

Google mnemonics for med school too.

You can easily get in med school if you have average intelligence and can memorize more or less well.

Caffeine?

Caffeine makes you smarter and durable, as long as you do not have pre existing blood pressure problems then drinking it is as harmful as drinking clean water.

The only risk in modern life is third wave feminism.

How to you respond to cucks that think we require a label on all genetically modified food? I pointed out to one of these cucks a vast majority of these foods are modified through artificial selection or simply interspecies breeding. They referred me to some autistic article claiming wheat has many health detriments due to the it genetically modified. I informed this individual that wheat has only been modified through interspecies breeding and there's nothing to be scared of. Even if there was a chance that "hardcore" GMOs may lead to health problems what's the issue? It's not like natural shit isn't going to do the same thing to you. It's not like cyanide and ricin don't exist.

The Jacobian Conjecture is a nice problem. Quite slippery.

A condensed study of traditional results for the 2-variable case (which is believed to be true) can be seen in Makar-Limanov's "On the Newton Polygon of a Jacobian Mate".

how unethical would it be to genetically engineer novelty life forms? e.g. making miniature versions of wild animals or extremely selective breeding to make comletely new species. I want to know how plausible it is to start a business like jurassic park.

Strictly speaking, ethics have no place in scientific discourse and inquiry. Science is not should, but could.

Unfortunately for could, should imposes itself upon us by our nature.

i can't find any resources to explain this to me so I come to science to ask for help.

If you have a fire burning at 1,800f then you throw a propane tank at the fire, does the explosion from the propane tank add +f to the 1800f? Or does it make the 1800f last longer?

And if you can point me to something to read about this or explain it to me that would be nice.

I don't know how it works but I think it works like that.

The propane tank will increase the complexity of the situation enough that an alternate path that uses doubles instead of floats will be taken to guarantee numeric stability.

There is a story circulating the internet than Hitler was saved from drowning as a child. It doesn't matter that the story is fabricated, obviously if he has drowned as a child the last 80 years would have happened much differently in almost all of the world.

Yes but its far more likely that your butterfly effect will either benefit or inconvenience people in minor ways than it will cause a disaster or the next holocaust.

The Butterfly Effect is a meme summary of chaos theory, which is severely misrepresented in the media but basically explains the behaviour of systems where a slight change in the initial conditions results in completely different outcomes. The simplest example of this is a double pendulum, as seen in pic related. The two pendulums here start out in almost exactly the same position and follow roughly the same path to start with, but the slight difference in their starting positions eventually manifests itself in wildly different motions.

People are however often too eager to apply this to the real world, forgetting certain 'buffer' effects and the fact that many events precipitate out of the zeitgeist of the moment. For example, WWI ostensibly started with the assassination of Franz Ferdinand by Serbian nationalists, leading to a cascade of mutual aggression pacts bringing the European nations into war with each other. Really though, political tensions had been high for a long time and the nations were all looking for any excuse to go to war with each other. In this case, the war was more or less inevitable and it was simply the assassination that set it off. The socio-econo-political aftermath of WWI is what laid the groundwork for WWII, which in turn laid the groundwork for the rest of the century. Thus, even if Hitler had never become Chancellor another populist leader may have ridden in on the back of the latent German nationalism and the story would have played out more or less the same, just with different actors. Or perhaps it really was only that one man who was able to precipitate the events that occurred - more extensive analysis might be able to determine one way or the other, but without a time machine and rights to alter history to check the hypothesis it's all just conjecture.

That's why the world is both easy and difficult to predict, it's a chaotic system but with 'buffers' of overarching trends.

mh honestly, you took the easy way out by trusting those sources...

i recommend you use better source for something like this. this is only caused by oversimplification of explanations. typical phenomenon...

try this, but preconceive that wiki also isnt 100% trustworthy or correct in general.

If I have a bucket of 10 unique objects and I pick out 3 samples. How many total samples are there?

10x9x8 would give me 720 but then for each set there are 5 more possibilities of obtaining the same set I think. Do I just divide by 6 and get 120? Is that right?

What I'm really asking is what's the best/quickest way to go about solving this?
>>
If you are looking for the total amount of unique sets with out regard for order, then yes, you divide by 6. This is known as a combination, instead of a permutation, which depends on order as well.

https://en.m.wikipedia.org/wiki/Combination
>>
10 choose 3 = [math]10 \choose 3[/math] = 120

Look up " probability and combinatorics"
