How does one program pic related?
What's the best programming language, ect.

>How does one program pic related?
wew there are 3 ways of interpreting this

>How does one make a program that plots the data like it is being shown in the image.
There are probably other valid interpretations. You obviously...

Thank you for kindly pointing out that my question was flawed. It made sense in my head.
My idea is that such a program will plot data that is retrieved from text files for day-by-day market valuation. Then have events superimposed as vertical lines with information displayed upon mouseover.
>>8203977
If it is going to be interactive then you probably need a full programming language and unless you are a genius then you probably want one that comes with free built in graph plotter class or library. (visual basic has this)
Then you can use clever programming to make a function that takes as input the position of your mouse and then finds what 'point' your mouse is pointing at and then you either have a formula that produces the message you want to show or have everything stored neatly in arrays that...

What exactly happens when you reach your breaking point?
Is there a difference between your perceived breaking point and the real one? Say if you are running and feel like you can't run anymore. What exactly makes you feel like that? Could you theoretically run a bit longer? Like say, if you were running in a competition you really want to win and not just working out by yourself?
And that is just an example. I am just curious what it exactly is that prevents you from pushing yourself. People would say it's laziness or lack of will. But surely it's...

I've experienced two kinds of breaking points - mental and physical.
Especially with physical stuff, the body's exhaustion signals can be ignored for quite a while, but if you're afraid of pushing further, you just give up. True physical exhaustion can't really be overcome by will - if the muscle isn't listening to your brain's commands anymore, having an iron will won't do shit to help you.

I thought about this and wonder: It seems like the belief is that successful people have a stronger willpower. But do they really use willpower?
Say they are working on a project that is very important to them and they are getting tired. They don't need to use willpower really to stay up don't they? The same way you don't need willpower when you are pulling an all nighter playing video games / binge watching a tv show / browsing the web.
But if you had to study for an exam you don't...

Hey /sci/, quick question here. When will evolution reach the end and why?
I'm a geology student. I've studied some paleontology. There is no goal of nature. It does what it does. The only way to answer that is to say that the ultimate end of evolution is extinction but you are more than welcome to travel to the future and find out yourself.

Very cool finding about tool creation and use by capuchin monkeys 750 years ago. I imagine they've been doing it even longer than that. Shame they can't get from sharpened rock to bow and arrow though.

that looks pretty cool but it was published in another journal
Do you think there is a health risk tied with the use of wireless radiation?
It's not ionized but on the other hand it's a type of radiation our body and system has never been exposed to before and we're soaked in it 24/7 now.
>>8203010
We've been bombarded by these waves 24/7 for the last 100 years.
If it was bad, we'd have known by now

There has been radio broadcasts for 100 years with wide exposing but now people have wi-fi routers and gadgets in their own home.

>it's a type of radiation our body and system has never been exposed to before
Nope, pic related. Every day, the Sun bathes us in the full spectrum of radiation, and much or the radiation less energetic than UV rays gets through our atmosphere. That means that the only radiation that isn't commonplace to us is x-ray and gamma radiation. Our wi-fi sure as hell isn't using either of those. It operates between microwave and radio frequencies.
If you turn a radio or...

I've read about life forms on gas planets and I've thought about floating jellyfish type aliens on gas planets. Furthermore I was wondering if it's possible for sort of conscious energy-ghosts to survive on gas planets, gas aliens operating from a higher dimension living on gas planets. Aliens that can somehow metabolize certain elements or compound(s) and convert them into other forms of matter and energy. I imagine they would look sort of like fluorescent squid-sludge-tornadoes.

Is there any ethical justification to putting papers behind a paywall? I mean, it's pretty damn fucked up that in this time of unprecedented ability to share information so much is being locked away.
Would you be in favor of doing something like putting in a proviso to at the very least government sourced grants that requires free public access to papers?
>>8202772
>government sourced grants
I would just defund those.
I would also not enforce copyright law. Let them have a paywall but if someone else spreads copies, not the government's job to prevent that.

Serious question time /sci/. Should I go into cancer-research? I'm about to start college in about a month, and while I always wanted to go into physics or astronomy, my dad (pic related), passed away 7 years ago of colon cancer, and his death is weighing heavily on my mind as I prepare to enter college. I've always loved physics, and my dream is to somehow be a part of NASA, so this certainly isn't an easy decision for me, however right now I simply want to be able to save as many people as possible from having to suffer the same shit that my family and I, along...

go for physics, follow your dreams
>>8204108
I don't know what's your goal when you get in physics or aerospacials, you can save thousands of people in those fields too.
Do what you feel like to do, both are noble goals.
Just consider the implications of each "career".
Forgive my poor english and don't give up on your dreams.
The final choice is yours, but by all means if you can see yourself in cancer research please go for it. One of my parents have it and Iam in nightmare knowing that he will die soon. Like you said no one deserve to suffer from cancer, it's a nightmare just to see your loved one dying without being able to do anything.
This is purely a selfishness from me, so do what's the best for you.

Is it possible for a hollow sphere to have equal centrifugal force at each point on the interior?
>>8203392
If the hamilton limit is drawn from daric vectors with open sets, then providing the inverse tensor is negatively charged, the centrifugal force will be equal at each elemental point as governed by their computational relations.
>>8203392
yes, if it is not rotating

Causation vs correlation
When a correlation is 100% strong, there must be a causation, right? But how do I find out the direction of the causation?
Let's take for example the observation that 100% of people who wear leather jackets are douchebags. Cam we conclude that leather jackets turn people into douchebags or that douchebags prefer to wear leather jackets? Which one is the right explanation?
>>8203297
>douchebags
Define 'douchebag'.
>douchebags prefer to wear leather jackets
This one, as douchebags exist without leather jackets, however this scenario leather jackets don't exist/aren't worn by anyone who isn't a douchebag.
As in, the wouldn't exist if nobody was ever around to buy them/wear them.
No.
>>8203297
The answer is both. There are myriad studies about how clothing, and specifically uniforms, affect human interactions and behavior within a given culture.
So pic related gives me the formula. I need to know if this is accurate and what the symbols in it mean. Can it be used as a power sum formula?
>>8202969
It's saying that the sum of 1/k from 1 to n is roughly ln(n) to zeroth order.
>>8202974
zeroth order?
>>8202979
n^0.
O(1).
A constant term.
