Is there any possible way to determine the degree of the polynomial? I know how to solve for it; I just need to know if there's a way to numericaly determine the degree.

I'm not looking for help by any means
I just want to clarify that there is a numerical way to prove the form of the function given the inital values
>>
>>8533827
Can you think of a polynomial with a different degree but that still fulfills all those conditions? If you can, then there's at least two polynomials of different degrees with the same information, and hence you know that that information is not enough to determine a polynomial's degree.

As a starting point, try examining the behaviour of simple polynomials of degree 2 and 4.

>>8533832
I did with a degree of 4th and found a solution.
I can't be done with a degree of 2 since the curve drawn out with my points is not symmetrical.

What is your /sci/ major and what are your professional ambitions?

I'm just about to start my Masters. It's only two years. I'm kind of freaking out about my future cause I basically have no real goal after I finish.

I love /sci/ence in general but have no particular interests. I like all kinds of problems.

I also don't like the path that one needs to take in academia. I don't want to spend my 30s as an assistant professor in tenure track. It doesn't sound appealing.

I don't even know if I want to be ambitious or have a more of a laid back job.

I'm majoring in mathematics and my aspiration is to go big in the field of computational mathematics.

Either get a six figure job at a big company or make some simulation software and get rich from it. Gonna learn game theory in the summer to see if that allows me to do something meaningful. I'm just a freshman tho so there is no rush.

After the dust is settled and I am living a comfy life I will then follow the steps of Wildberger. Maybe make my own youtube channel with my own axiomatic foundation for computational mathematics or if in the time I was busy his axioms made it big then I would do research in the field of 'Wild Math' and get my PhD in that.

We need to talk about base 12.

I know it's autistic to believe that we will ever switch to base 12 on a wide scale, but can we have a fap thread where we fantasize about a world where we use base 12 instead of base 10?

It allowed us to get away from the analytical standard that before was a thing.

Now with computers approaching things numerically could even be called the preferred approach.

alright boys. I want to enlighten myself. I have $130 to spend on books and i'm trying to teach myself math and get to the more advanced stuff before i attend uni next year. i have a ok understanding of algebra and i skipped out of trig class so can someone recommend some text books i can get to lay down a foundation and then some textbooks i can get in the future to further my studies

How come an electron doesn't fall into the nucleus?

I did some research online but there are literally a dozen different answers.

The most satisfying explanation was that according to quantum mechanics, the electron is a wave with probable positions, and it actually does fall into the nucleus with a high probability of finding it in the nucleus.

>the electron is a wave
No. It's a particle but behaves like a wave.

>>8532373
I thought it was a wave but depending on the localization of the wave packet, you get either particle-like effects or wave-like effects

The manifestation of Material Objects into the World started yielding diminishing returns a long time ago. The Technology of 1916 was qualitatively and quantitatively superior to that of 1816, but the Technology of 2016 is basically identical to that of 1916.

It's over.

Essentially, you are right. I had read an article about this some time ago:
https://aeon.co/essays/has-progress-in-science-and-technology-come-to-a-halt

From an academic point of view, personally, I see the current way of rewarding academics as one of the causes. Instead of letting people go about their own research in peace, they are being pushed to shit out as many insignificant publications as possible.

From a more general, social point of view distractions play a vital role in making people less able to just focus on their own ideas and develop them.

There is also the shift that happened in the 80's that pushed researchers into the free market, forcing the most intelligent in our society to make trinkets that can be sold quickly. Instead of working, at Bell Labs, where they would have virtually unlimited funding (from the telephone monopoly in this case) and coming up with the transistor, they work work for Apple, and make Idiot-Phone 7, an XBOX or other pointless crap. Actually, breaking up the Bell telephone monopoly is one of the reasons for this...

I like your camelback locomotive OP. Because I deal with thermodynamics, I raise you a more scientifically designed machine.

We are probably seeing the early signs of the knowledge event horizon. The more that is known the more you need to learn in order to gain new knowledge. In other words nearly all the low hanging fruits have been picked.

100 years ago Nobel prize winner like Einstein were in their 20's. Today they are in their 70's.

It has been studied and done before by anyone that studied harmonic oscillators, and they are pretty popular in physics
