How common are macroscopic parasite infections?
Are they prevalent where you are? (and which country you're at?)

Do anti-parasitic medicine work?

How do people end up diagnosing their infection?
I can't imagine a case where my doctor actually believes someone's concerns for parasitic infection. Are people overlooking potential parasitic infections? Can they go unnoticed?

Is this equation... anything?

I'm a fucking first year CS major in complex analysis and abstract algebra. Just thought I'd inform you that you're going to lose a job to me someday.

The limit of a function f as x approaches infinity is L if for every number M > 0 there exists a number N such that for all x>N we have that |f(x)-L| < M.
For example, the limit of cosine(x) as x approaches infinity does not exist. The limit as x approaches infinity of 1/x is zero. The limit as x approaches infinity of (1+x^-1)^x is e.

How does it feel to know that you will never converse with someone so intellectually superior that they might as well represent the next step in human evolution?

That you will never witness for yourself the absolute pinnacle of human intelligence?

That you will never know the feeling of talking with someone who by definition is the smartest person on the planet?

That you will never lay eyes on someone who could effortlessly outdo universal polymath geniuses such as leibniz, galileo, newton, wolfram, davinci, descartes, and so on?

Unfortunately our 1 in 500 years genius died in 1957.

He made major contributions to a number of fields, including mathematics (foundations of mathematics, functional analysis, ergodic theory, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, fluid dynamics and quantum statistical mechanics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.

He also single handedly saved us from the russians. If it wasnt for him we would all be either dead, or speaking russian right now.

Please bow your head in a moment of silence for humanity's last great polymath.

I don't quite think you understand how economics works, senpai. You don't "deserve" anything, you get what the market is willing to pay for your skills.

>>7971906
No.

>>7971916
Does the market understand the implications of the actions and choices made? I am not sure.

Most people will not care about R&D but expect new gizmos to materialize on the shelves. Except from when they get old, frail and ill, needing new medicine. by that time, however, it is way too late as medicine takes 15+ years to develop by which time they will be dead by their own decisions.

Not sure "deserve" is the right word. You might say the market deserves the consequences of its actions. And that is not always nice.

From what I can tell, all of mathematics has geometric representations. Euclidean or otherwise. Are there any mathematical objects which do not have this quality?

>geometric representations
what is this ?
>>
>>7975012
My excuse if that is not a precise term. But what I mean is, for example, you can visualize the real number line by a graphical numberline. I specifically did not use the word visualize because even with things like 4D geometry, you can't truly visualize it, but it certainly has a geometric interpretation.

The term "quantum mechanics" sucks and we desperately need to change the name for two reasons:

1) The word "quantum" promotes all sorts of woo and shitty pseudoscience that convince retards that they understand shit.

2) IT'S NOT EVEN ACCURATE. Position is never quantized. Momentum is never quantized. Energy is only SOMETIMES quantized.

We should teach "quantum" mechanics as Matrix Mechanics as Heisenberg initially intended.

uh you dont really get why its called quantum at all do you

It's called quantum mechanics because of tradition, nothing else. It's a shit name that serves to only confuse people about the real physics going on.

Yes, for women sex is the only thing that matters in their life. Women are naturally purely sexual creatures. It's their only purpose and the only reason for their existence.

Engineers should be the only ones who are allowed to call themselves mathematicians. By definition you are not a professional if you are not paid to do something in the field. Engineers who sell their software using their algorithms, services, product patents etc. are actual professionals applying math to earn a living.

By constrast you are not paid directly to publish an academic paper. At most you are paid directly to be a faculty member. You are allowed to call yourself a TEACHER, nothing more.

I used Excel a few weeks ago to plot some data from a simulation that we had to do in the Programming course and when the proffesor saw that I plotted it in Excel he said "If I were the Dean, I would have expelled you right now" (he's the Pro Dean)

I know this topic has been discused at least one bazillion times.

What does /sci/ think of Economics? Is it an actually useful science? Or a bunch of inaccurate theories that hold no predictive power? What about its value as a piece of mathematics?
35 posts and 3 images submitted.
>>
Economics is not a science. To be a science you need to be able to perform controlled experiments, which economics cannot do (artificial studies with undergrad psychology/econ students don't count).

It's the same reason why none of the social sciences are actually science.

>>7970072
Wait, /sci/ has tripfags?

Not strict science, but still incredibly useful. Same as most other humanities/social sciences, save for things like critical theory.
