Why is being in medical school seen as such an amazing thing to be in by the average person, while they couldn't give a fuck about advanced degree in other hard or harder subjects?

Everyone knows about doctors and everyone knows they make good money.

If you are like most people then at some point in your life your parents probably told you that you should be a doctor.

Basically because it is a meme and that implies that it is popular. Everyone knows about it so everyone talks about it. Nothing special here.

I'm trying to learn a shitload of things before I die so I can be able to create. How do go about learning such things effectively? Methods to learn and also the medium I should learn them through.

I'm sorta low IQ, so I kinda want to know how best to approach.

Getting married soon.
I don't really care about anything else but STEM.
I tried getting rich before I graduated high school with some cheap gimmicky web app ideas. That never worked. I was going to use the extra time/money to broaden my studies. I want to learn everything.
Now I'm just a DeVry drop out making $115k a year stuck in a vicious cycle. I really don't care about anything else but my education.
I may never conquer the world, but I know the only place I'll ever find friends is with those who feel the same way I do about STEM.

ITT: your lifes passion for w/e STEM.

The first question that arises is why, assuming you're as ambitious and thus reasonably intelligent as you say, you'd let your gf meme you into the marrying spiel. It's all win just for her, the only card she can pretend to play is that our relationship is saver that way - while rather the opposite might be the case.

Anyway, what did your apps do and did you develop or also business?

>>8271517
I was just venting, honestly I'm stressed with this kid coming.

>Why?
To bring incredible magical A.I. to life & finally feel something worth feeling in this existence.

>Anyway, what did your apps do and did you develop or also business?
I never started my own business, if that's what you're asking.
I'm actually working on those apps now. If I give away the main features it may hurt me.

I am working on a chat system now though.

Your options:

1. Save up some money, quit your job, get a cheap place to stay, go back to school. Keep the wife only if she's ok with it.
2. Make sure you have the least-demanding job possible with lots of free time. Self-study like a pro. Warning: if you do it this way you have to stay disciplined yourself. This may involve neglecting the wife to some degree too.

It will help if you can get a source of passive income like making another app. But this may take a while and requires some luck.

we always talk about greek mathematics and how Euclid is the "father of geometry", but that is a Eurocentric belief

Egyptians and the Babylonians had concepts of geometry way before Euclid and the Greeks

focusing on greek mathematical history is not "eurocentric"

The Greeks were the first civilization to introduce mathematical proofs and Euclid was the first to establish an axiomatic system for geometry essentially launching the formal science of mathematics of today.

So while the Egyptians and Babylonians had mathematical concepts...more so the Babylonians, the Greeks were really the first to revolutionze math on such a fundamental level

Can someone explain to me how a double pendulum doesn't debunk predictive physics ? It's just two pieces of metal and a joint yet the movement is completely chaotic and undefinable mathematically !

I think it's high time we really start reconsidering how much faith we can place in the concept of a stable ordered reality whenever something like this exists.

If I flip a coin and you can't predict which side is gonna fall up, does that mean that it's indeterministic or that you're just a brainlet with a small dick who is incapable of calculating physical simulation with all the variables ?
>>
>>8271258
This is a contained energy equation system where as a coin is an open variable platform. That science cannot even predict something as basic as the pendulum with all the advanced computer modeling available to us shows that at the very basic fundamental level they have failed us.

>contained energy equation system
Please list all the variables taken into account and show me how each of them were calculated

There are two approaches:

[math]1.[/math] Leaving unclear paragraphs for *later*.
[math]2.[/math] Tackling doubts mercilessly.

The second approach is exhausting. Where do you find the energy to be productive and do honest math?

It depends, if I'm in class, I usually opt for 1, try to write down the proofs (well, at least enough of each proof to be able to redo them later) and get the general idea. If I'm reading a book, I opt for 2., but as a consequence I rarely read for too long.
I have a good friend who is also very passionate and he does the exact opposite. He always asks the prof (or me or his neighbours) questions in class if something is unclear so as not to leave anything out. However, when reading a book he just skips through and tries to get the general idea.
I have never understood how someone could keep reading with gaps in their understanding. I think I can do that in class because the professor usually gives intuition, willingly or not, about what should be obvious and what is not (even through the intonation as they are speaking).

How is [math]0.2746893852970634624136253005...[/math] related to [math]e[/math]?

I know they're related, I just can't find how. If you can find a relation between the two where the link is a known number or an integer, that would help me a lot.

By relation I mean like you can express the number as some function including e and simple numbers like the integers and known numbers like pi, phi, etc.

Examples would be 1/e, e^pi, e+2

Why would candles burn longer when you add salt (NaCl) to them?

One could hypothesize that salt dissolved in the molten wax would change how it flows, possibly making it travel up the wick slower.

I don't think that explanation works though - the wick would just burn shorter. My guess is it doesn't actually have an effect, that piece of folk wisdom is the result of poorly or not at all controlled experiments

Does watching videos on an electronic display damage your eyesight?
By that I mean, does it mess with your brain's ability to focus your eyes?

Many videos and images are low-quality, the clarity of areas of an image are not dependent upon our eyes because the entire display is pretty much the same distance from our eyes. As far as I know, avoiding any attempts at automatic focus/adjustment when viewing artificial depth of field effects has had no place in our evolution/development.

I suppose the same thing will work for any photo editing, digital art, or even video games?

my mom always said that I get square eyes from all the screen glaring, I lold back then.

now I can't focus on faces in a distance ortho my optician said I dont have an impairment.

Id say its the resolution of the hardware damaging not the resolution of the displayed content

fuck
>>
>>8271122
I think the glare was always a red herring but my point here isn't so much about resolution as the human eye not being adapted to simply letting content be out of focus.

By resolution do you mean a low pixel density? My thoughts were that this only exacerbated the problem but wasn't necessarily the root of it.

I would imagine this would be more of a problem when you have a moving image (like a video or game) compared to a still image.

Please do correct me if I am mistaken.

No. They are simple and useful. There exist transcendental numbers? Obvious. The very foundations of measure theory being at all meaningful? Requires countable vs uncountable infinities. The distinction is elegant and inextricable from mainstream mathematics.
