¿can anyone help me find the first root of the equation [math]-x^3+3 x^2+\log (x+3)=0 [/math]?
it should be near 3 but can't seem to find it, not even in the plot is shown

[math] x_0 = 3 [/math]
[eqn] x_{n+1} = x_n - \frac{-x_n^3+3x_n^2+\log(x_n+3)}{-3x_n^2+6x_n+\frac{1}{x_n+3}} [/eqn]
[math] x_n [/math] will converge to your root

It's true that science has been seen as a men's field solely because of the gender roles placed on women, and that it women would be just as represented as men if it wasn't for their gender roles.
You might think this is a non-issue, but the effect is that the masculinity of the sciences has neglected women's issues due to their under-representation on the board.
Does /sci/ agree that companies should seek more women in tech, as it would better humanity as a whole?

How are questions in science biased by gender?

Your question makes no sense, idiot. Here's the tierlist, from hardest to easiest:
> MATHEMATICS
> PHYSICS
> ENGINEERING PHYSICS
> APPLIED PHYSICS
> APPLIED MATHEMATICS
> CHEMISTRY
> BIOLOGY
> EXERCISE SCIENCE
> computer science and it

Try harder, obvious bait is obvious
To be clear though, in case you're actually THAT autismal, im not saying compsci is difficult nor did i ever mention/compare those other subjects. I want to hear from someone who has experience with the comp sci major, or at the very least, is not an uneducated bafoon. Good day sir.

If hypothetically there was a God/higher power and he created the universe 6,000 years ago in a way to make it seem like it was billions of years old and endlessly vast when we became technologically advanced to measure it wouldn't it still be impossible to mathematically prove?

unfalsifiable therefore not science-related
>>
>>8661558
even if that were true, since god made everything else in line with a billion year old universe then it wouldnt matter.
there should be some physical hints that that's what happened however.

My father drowned a few years ago.
The many-worlds interpretation appears to be correct. And, even if you disagree with that, the universe appears to be flat and therefore infinite.
Given that, do you guys think that my father is basically alive, in most universes and in most parts of this infinite universe? And I just happen to be living in a freak part of the multiverse where he died randomly, which may make my experiences worse, but at least most versions of him are living his life out?

Optical Wireless Communications too, not just Li-Fi
>>
>>8661454
It's technically feasible and offers a lot of advantages (especially with respect to bandwidth), but considering the drawbacks as well as the fact that most applications will be bottlenecked somewhere else anyways, it's not worth implementing yet.
>Optical Wireless Communications too
In a broader sense, this is a lot more practical and advantageous, especially for telecommunications infrastructure at the backhaul level. A fiber-optic cable could be replaced by a series of laser transceivers, avoiding major easement costs and hurdles.

In the real universe is there such thing as a probability that isn't 100% or 0%?

Probability is a mathematical construct and thus not part of the real world.

Everything in the known universe is exactly 50/50.
It either happens, or it doesn't.
>>
>>8661415
It seems everything should be 50/50, though an "effective" (subjective) odd could be more or less, but never 0% (or 100%, the complement).
However, if I flipped a coin a hundred times and it turned heads all times, I might give it better odds of flipping heads again. But then I doubt anyone has honestly flipped a hundred heads.

All things medicine (especially genetic modification).
Healthy living.
I personally am concerned about things that I do not see any plans to address, including:
Nutritional soil depletion
Fresh water supply
Overfishing
I think, for the most part, humanity has conquered the environment. Now we have to figure out how to support even more people over a long period of time.

you can't just look at salary m8. you have to look at the area, the cost of living, the working hours, etc.
its the whole package and not just the number on your paycheck.
i turned down a 125k maintenance gig in oakland because, well... its in oakland.
any salary over 80k suffers from serious diminishing returns in terms of happiness per dollar.
>>
>>8661327
Probably a lot of hours/overtime doing challenging & interesting work. I'm trying to weigh it against a startup that pays $100k. But in a higher cost of living area.
I'm a little concerned about the risk with the startup. Also the startup's plans are very ambitious, so it would also be a ton of hours doing interesting work.

Let me start off by saying I am NOT a Flat-Earther or Geocentric believer, BUT I am creating a sub game in GURPS (the tabletop game). I was going to go to /tg/, but I don't need neckbeards explaining rulings to me, I need people with STEM backgrounds to help me create an "as accurate as possible" mythical world.
So, looking at this from a mythological standpoint, I'm wanting a flat, disc-shaped world, the continents and land masses scattered across an ocean, and large ice walls hold all the water from "falling off" into the void below. This implies that gravity has a "source" below everything. Many mythologies believed that the earth was "domed" with "the firmament". This furthers the idea of "light mass". "Light things" weigh less than "dark things". Suns, moons, stars, planets, and other celestial bodies are... Separate of these laws?
I'm not sure... This is what I need help with. IF the science of this world could justify the existence of this kind of cosmology, how would it work? Sorry for the long post, just spitballing my ideas.

Try reading the "Discworld" series by Terry Pratchett. Aside from his eloquent use of the English language, he incorporates magic as a sort of force of nature to allow things to happen.
Other than that, first you'll have to explain how the disk is rigid enough to overcome gravity's force to render it into a ball.
>>
>>8661451
I assumed I was going to make the "foundation" of the disc a fictional substance, for example, Adamant, that would be able to withstand the force and keep it a level platform.
"Magic" substances help fill the gaps where science would (obviously) prove this type of world wrong.
And I will definitely look into it.

I'm a 25 year old NEET. Is there anyway I can become a robot in terms of work ethics. Not a real robot. I just want to have the work ethic and drive of someone like Henry Kissinger.
tl;dr: I do nothing all day. Is it possible to do work and studying from morning till night all day everyday?
