im doing a physics problem relating to angle of refraction and im trying to find the angle of refraction without the material constant. iv managed to get the angles down to a kite shape.
this is my main question.
if angles a and d are 60 and angles b and c are both 120, can you assume that sides a and b are congruent? using the pic. will explain more if i get an answer
>>9154247
Yes
>>9154247
A and D are not the same, though.
Source: I know stuff about kites.
90909090=180
12012012060=420
sure.
120 give idea is some other gonic

Is it as easy to define as to say that it's the entropy of the previous dimensions before 4D?
Time is the direction you go in when you want to collapse a probability wave.
If you wanna go quantum, you need to go backwards in time

Thanks broski.
I'm probably screwed
If I was a chemist instead of a mathematician, I would be glad to. Unfortunately, my knowledge of chemistry is limited to a little bit of quantum mechanics and the fact that vinegar and baking soda makes fizz.
Amazing how I can know so much and still be a complete idiot.

Why do fiberoptic cables manufactured in microgravity have less imperfections (and thus work faster and require less electric input) than ones produced on the surface of the Earth?
The primary factor is the lack of gravity, but what does that do differently?
>Left, a fiberoptic cable made in space.
>Right, a normal fiberoptic cable made on Earth.
I have to imagine there is a stage in the reorganization where a miniscule force (gravity) interferes or promotes certain imperfection causing behavior.
>>9153767
Supposedly less crystallization:

Probably has to do with the way we pull fiber on earth which is a gravity driven process. Pic related needs a huge tower
>>9153806
Nope, the glass they use wants to separate out into it's different constituents because of gravity:

If humans are 60% water, how are we mostly made of carbon?
Checkmate, scientists
Well you see, Carbon isn't technically found in the environment naturally. Where as water is a natural occuring element in the environment therefore it is 100% of a human is made of water.
No accounting of the body has us as mostly carbon. Perhaps if you removed the 60% of us that are water we'd be left with mostly carbon. At least by mass.

For people who have kept notes at their time in uni, do you actually reference or go back to them? Or are they for the most part useless? Contemplating throwing some I kept away.

I used to carry them around with me but it was too crazy after a few moves to different cities and such. This was a time before the cell phone though. Nowadays I take a picture with Adobe Acrobat, they have some sort of archival mode on mobile, and back everything up to PDF.
As an avid "journal" type person the only use old writtings are to me is for CRINGE and disgust at how stupid my previous self was. Simultaneously proud at my accomplishments.
>>9153372
Scan them in, or put them all in a big ordner and store it in a place it doesn't bother you. If you throw them away, you can never go back and look at them and if you stow them away somewhere they don't bother you, you still can.
My notes are mostly rubbish intended for short period use, as in I can use them after a month or so since I still remember the context and such but looking back after years its all gibberish
I've been watching Robert Saposlky lectures and in one of them he mentions paper titled "Optimal Benefits of Percived Madness". Does anyone have it since I can't find it online ?

Does nofap improve grades and cognitive performance?
Asking for a friend.
masturbation only does not affect your academic performance, however, masturbate reduces sexual tension, which can improve your performance, but at the same time, nofap makes you waste less time, which also improves your performance.
In the end, unless you have an addiction problem, masturbation makes little difference
>>9153296
Masturbation might also hurt your grades if you go on 10 hour long adderall fueled masturbation raves

how can we exist if things must be infinitely divisible but infinity can't exist?
From that line of questioning, either things aren't infinitely divisible or infinities do exist. Are things also infinitely multiplicative?

prove it
>infinity can't exist

Quite fascinating.
The truth is:
Maths are perfect, the universe is not.
Or at least, our knowledge of physics is very limited.

Does the human brain have a programming language is it the final bridge for artificial intelligence in future computer
>>9153109
>Does the human brain have a programming language
No. Programming languages are just tools that let human programmers write instructions in quasi-english so they can be compiled into machine code that would be a lot more of a hassle for a human to have to try to work in terms of. Because no human programmers need a tool to make it easier for them to program human brains, no programming language exists in nature for human brains.
>the final bridge for artificial intelligence
There doesn't need to ever be a final anything for AI. There have been good developments made already and future developments will probably be similar except with a lot more computing power.
>>9153109
Yes. You are on the right track to general AI.
The highest abstraction level of human beings is based on language. Meaning the same functions that say form a sentence or create an equation are the same that tell us in winter it will be cold.
The reasoning part of human beings, aka intelligence, is likely highly tied to our language capabilities. Now this doesn't mean that someone bad at english is stupid because math/english are both just languages with concepts, structures, etc.
So yes, You would assume that a general intelligence would be a very high level abstraction that used something similar to english to relate across all sorts of different fields and sub-AIs that did other things.
For instance an image analyzing AI would be underneath and used by the General intelligence portion. Which would likely be something very similar to human intelligence (at first) in how it creates language/sentences/relationships/reasons via language.
>>9153195
You seem dumb btw. All human language is a programming language meant to be interpreted by human brains.
"Go to the kitchen" is not explicit instructions. It must be interpreted by a human brain with it's own contextual understanding of the words and meaning. Human language is a programming langauge just not for computers.
>>9153217
except it is not.
programming language programs instructions but cannot program a state of being.
I am gay
you can't program that.
A question about complex numbers.
Have I understood it right that [math] {z:\textbf{R}e(z) = \textbf{I}m(z)^2} [/math] where [math] z=a+ib [/math], is the same as [math] {z: x=y^2} [/math] because the real part of [math] z [/math] is [math] x [/math] and the imaginary part is [math] y [/math] ?
>>9152962
There is supposed to be "{" and "}" around the expression including " [math] z: [/math] ", it didnt show up weirdly
>>9152962
You've completely screwed up your notation, but this is so trivial that I'm just going to assume you've understood it correctly.
How can boolean algebra represent all of math?
How can computers process functions, graphs, advanced mathematics using only boolean algebra?
>>9152931
what is a Goedel number?
>How can boolean algebra represent all of math?
Everything in math is logical, and therefor can be represented with all those qt logical symbols and "operations".
>How can computers process functions, graphs, advanced mathematics using only boolean algebra?
They can do analytically all the simple things, but most of the times they a p p r o x i m a t e the results, or "numerical solutions" as they say.
For example, let's say the pc can't calculate the derivative of f(x)=x^2 at x=3, so what it'll do? Do the secant between very close points, like 3 and 2.9999995.
Now I exaggerated a little bit on the example, but boolean algebra can easily deal with those approximations.
