---------(x^2+5)^2-15(x^¨2+5)+54=0-----------
Substitutions method
x^2+5=t
(t)^2-15(t)+54=0
Pq formula
t=-(-15/2)+-√((-15/2)^2-(+54))
t=7,5+-√(-56,25-54)
t=7,5+-10,5i
t1=18
t2=-3
>>>x^2+5=t
---------------Roots--------------------
x^2+5=18
x=3,6
x^2+5=-3
x=√-8
-----------------------------------------------
>>>Yet my textbook claims this is the answer
x=+-1

When did you have your first existential crysis /sci/?
Do you think the time you have one is relative to intelligence?

Existential crises are brainlet-tier.
It should be obvious to anyone with any amount of intelligence that life is meaningless. That's really not scary - it's exciting. You get to pick the meaning of your life.
If you can't come up with a good meaning, you're probably retarded and will have an existential crisis. If you're smart, you'll come up with something worthwhile.
I've read some conflicting reports on black holes and spaghettification. Does it occur before or after entering the event horizon?

It depends on the size of the Black Hole. "spaghettification" is really just tidal forces. Tidal forces and the radius of the event horizon (the Schwarzschild radius) scale with mass linearly. However tidal forces fall off rapidly with radius (r^-3) so a bigger black hole has smaller tidal forces at the event horizon.

No, they're spherical.

The concept of IQ usually has people confused, but what IQ is trying to analyze is pretty good.
Although NONE of the tests are perfectly reliable and most of them don't mean anything yet since the concept of IQ is still growing.

How do I do it? Do I risk injuring nerves?
Wisdom tooth came out nicely years ago.
Now it's broken on the side and gone.
The dentist told me that he has to pull it out but it will take me some time to reserve another visit.
It's been a week now and it hurts every day.
I swear they used a screwdriver to loose the other one I was having problems with.
I'm planning to loose this as well using a screwdriver, then pull it out by hand.
Any advice?

I have acetaminophen/paracetamol and alcohol (not used to the latter).
The slut anesthetized the nerve before pulling the other one out.
I hope it doesn't hurt much since the tooth is already compromised.

What keeps you excited about the expected upcoming scientific advances?
I've already assumed the electric automated cars paradigm, and in a way, many of us expected the electric car to take off much earlier.
Then there's the shift to renewable energies with solar becoming cheaper. But it will take decades.
What keeps you excited? Any interesting upcoming advances in less than a decade?

If we fast forward climate change and make it visible we can finally convince all the normies about it but not just that, the government would get a reason to start funding science like never before, that's why i've been releasing as much greenhouse gases into the air as much as possible, you autists don't know how shit works.

Should science aspire towards the correspondence (ie Popper) or coherence (ie Kuhn) theory of truth?
Personally I prefer the pragmatic theory, but since it's not even in contention I'll take coherence as a close second.

Given that we only speak of things "necesarily being able to happen" if given enough time it will happen, yes.

Yes, given infinite time (which we don't have), anything physically possible will happen.

So recently I rewatched Intestellar, and I was asking myself, would't it be harmful to be so close to the accretion disk of a black hole?
I would imagine the disk would emit a lot of heat and radiation

If a want to have an understanding and practical knowledge, enough to read anything without difficulty, or a general understanding about the universe and how it works.

It's a tiny fuckin dot (nucleus) with a cloud of location that the electron could be.
There is no "what does an electron look like", there is no "look like" at that level, it's a single particle where kinda can tell where it is or kinda can tell how fast it's moving, that's about it.

Ok thank's for replies.
