Why do normal people hate math? Put anything more complex than arithmetic in front of them and their minds shut down.

Because the media tells them it's only for autistic nerds and that you don't need this math to be successful

Also it's better that we keep it likes this or else Math major will become the new CS and i'm sure you don't want that

Red pill me on nuclear power and its dangers vs benefits

Also serious question, why haven't we banned third world countries from using it? It's not that they can't be trusted, but with the amount of criminals in this world; last thing they need is their country going to complete hell

Because you can't just impose law on a foreign sovereign nation. Is this a serious question? If those countries truly can't handle nuclear power generation then their governments will not produce those plants.

>Does anyone ever feel like we are all monkeys and our society is the monkey world from planet of the apes?
yes

>I mean have you ever really listened and compared our languages and laughs to animal noises?
yes. there's a huge scientific literature on this. human language and primate communication are completely different. it's been argued that human language and "animal noises" such as chimpanzee vocalizations are totally unrelated phenomena.

>When we laugh we sound just like monkeys.
well no, they don't, but I could see why as an indiscriminate listener would make that hyperbole.

Hello /sci/,

I was doing some homework for my economics class when I happened upon this homework problem concerning Taylor's rule. Most of the time the highest level math I need to know is basic algebra, but this rule required us to derive.

Calculus is a mystery to me and I don't understand how all the manipulation that go into reducing many terms into a finite equation works. Thankfully the assignment provided the derived form of the equations used, but I was wondering if any of you math wizards could explain how this derive happened?

Also, how do I get better at higher level math? Is it simply a matter of remembering rules for manipulation or is there some other key? I look at it and it's as if I'm trying to read mandarin Chinese.

first order approx of f(x) is just
f(a) + df/dx(a) * (x-a)

notice that you must know f(a) , usually a=0.
The approx holds for a small neighborhood [x-d,x+d]

You probably just need to get used to the notation and learn more about infinite series.
Taylor series are used pretty much everywhere, they're very basic (maybe too much). You're basically approximating the graph of a function with a polynomial function (usually a straight line), as you can guess it's a horrible approximation except in a very small region of the graph.

Hello all, it is that time of the year again. To everyone within difficult schools and with strenuous course loads; how are you coping, and what are good strategies to not become overwhelmed with anxiety and despair? What is your current academic and grade standing- both prospectively heading into your final exams, and overall? What have been your biggest regrets, and how screwed are you in reality in comparison to your current stress levels? And how do you plan to avoid binge drinking/eating/procrastination?

From what I heard, a new nuclear power plant hasn't been built since the 70s. People say it's due to increased regulations which increases the cost of building new plants.

Is this true?

It's not lack of money or profitability that stalled or withdrew those applications
It's the years passing by without getting an approval, hundreds of millions spent on EACH APPLICATION without a spec of real work done on actually building the power plant.

And of course almost all the cost is regulation too

You can't blame them from trying to play safe. Nuclear Liability is a huge issue.

Fukushima cost $40B and rising. That kind of liability demands high amount of regulation.

>STILL know no more about gravity than some perma-virgin in the 17th century

Is it time we accept that we have arrived at the physiological limits of our nervous systems and their ability to formulate increasingly distant abstractions?

Why do so many assume that knowledge is just empirical and will always progress? That may be true for the simple observations of the natural world that we have so far made, but perhaps we will never be able to tackle and unlock certain problems - they will remain mysteries until the end of this specie.

Enjoy being a race of stunted brainlets.

People are arrogant and fearful.

The models we have work very well for general purposes. There's no reason to think all of it is fundamentally wrong because a couple pieces don't fit quite right.

But the current models strike me as pretty damn clumsy... Shit, using something like probability densities to try an explain the distribution of a theoretical negative charge? Fucking wave-particle duality? Broad incompatibility between small-scale models and macro-scale models?

So sure, coincidentally a few of these models happened to work and allowed us to build a fucking iPhone, but there hasn't been any new paradigm of understanding proposed since the 1920s...

Why is it so difficult to accept that we have arrived at a limit?

Just like your dog will never learn calculus, humans may never develop an understanding deeper than what we already have.
