Pretty sure its the website. If the first sentence wasn't there then I could see a way it would be false, but not if it's guaranteed to be differentiable.

Oh wait it should say "monotonously" decreasing and not just decreasing for it to have to be true.
Still a misleading question though, not really a misconception.
>>
>>8483020
Maybe it's the wording? They might mean that decreasing = not increasing != strictly decreasing.

Can you help me /sci/?
My mom(I do not live with her, I merely visit her frequently) believes in pseudoscience bullshit such as chakras, healing crystals, energy vortexes, alternative medicine, pineal gland third eye, and all kinds of other bullshit. She commonly brings scientific terms into the discussion to make herself sound smarter and consolidate her arguments. She states that she is "ascended" and that others are beneath her and also states that she is open to all discussion despite ignoring any replicated experiments or counter arguments that bring "negative energy" into her house.
Is it possible to fix people such as her, or is she to far to recover?

What is opinion on Cryogenic Freezing? In theory it seems breddy cool.

That is 0.0000001%.... Right now. There are major advances in medicine all of the time. Honestly, that might be a very viable option with the fact that antibiotics are going to quit working soon.
>>
So flash-freezing something minimizes tissue damage, right? And that's why cryonics is more successful with small samples of tissue than it is with full living animals?
What if you, well... jammed cooling tubes into the tissues to increase heat transfer rates and flash-freeze the body from the inside-out? Would that improve chances of success?
I mean sure, you'd be causing a ton of physical trauma to the body, but it's still gotta be better than widespread cellular destruction, right?

Pressure doesn't have units of energy dude. Your question is nonsense. You have to be doing work in order to change a system's energy, and pressure doesn't imply work on it's own.

THIS is my theory of how the universe was created but the thing about this theory is that is a big hoax but here it goes so read carefully.
My theory is that there was a universe before this one but that universe had a big black hole that only got bigger and bigger eventually that black hole absorbed everything in the universe and then it reached its limit and then exploted and thats what we known as the big bang and then the same thing is going to happen with our universe we are just going to be recycle over and over again theres no end to it theres no point to it just continues is a never ending cycle that never really start it and that never really is going to finish we don't know how it start it we just know that its there.

This sounds like bait, but could this actually happen?
If a black hole merged with other black holes and it began to engulf the universe, could it detonate after ahwhile?

Next semester I'm taking physics 2, calc 3, differential equations, and linear algebra. Everyone I've told my schedule to so far has laughed awkwardly and looked concerned.
This can't be that hard. Right?
Pic unrelated.

None of those classes are hard if you're not a brainlet. It's a lot of practice and homework problems is all.
Who are you telling that looks concerned? Non-STEM majors? This is standard 3rd semester for any STEM major at my university, with either 1 or 2 major related courses on top of it
>>
>>8482119
Ive never heard of someone taking calc 3, linear algebra and diff.eq at the same time, usually because calc 3 is a prerequisite to linear algebra and diff,eq, and sometimes linear algebra is a prerequisite to diff.eq.
If you're an engineering major idk why you're taking three math classes at once, OP. If you're a math major, well... You're a math major.
I've taken more than 1 math class a semester. Non-stem majors will cringe because they've been trained to think you can only handle one math/science a semester

I spoke to civil engineer, a bio major, a pharmacy grad student, a mech e major, and my chemistry professor who audibly groaned when I told her.
The pharmacy kid told me to prepare my anus, and to have fun, but everyone else acted like they were concerned for my well being.

I'm planning a book where characters spend large amounts of time in zero-g space transit, but with minimal opportunities for the physical exercise that would be needed to stay in healthy condition. They are strapped in a small cockpit that only allows space for stretching, with no exercise equipment. They only occasionally dock in space stations after long periods of time in zero-g, and stay at these stations for a maximum of a few days, with no professional physical rehabilitation, before going back to zero-g.
How long would it take for physical deterioration to set in, and how severe would it get?

Well, the body will see various tolls over time, but I think I would be being conservative in saying that after 6 months of such, they would probably have at least 50% bone and muscle loss from atrophy, they would be losing their vision/going blind, losing their hearing/going deaf, and there's a good chance they would be dealing with kidney stones and very regular feelings of nausea.
If they didn't work out for that time, they would probably lose their ability to walk, and have various respiratory issues within those 6 months. Basically speaking, the situation you are imagining would basically be torture for every member of the group.
>>
>>8482622
Would these changes eventually cause death, or just make life painful? I think I may have to make the visits to the space stations more frequent if pilots will be losing their senses though.
>>
>>8483370
No, they would absolutely die in a very short time. Humans are not built for space. I would suggest reformulating the context if you wanted to be realistic.

So I just found out that if you want to know if a third grade polynomial [ax^3+bx^2+cx+d] has a third root [(m+n)^3], you just avoid checking the matchs following [m^3+3nm^2+3mn^2+n^3] using this small equation:
[a/d=(b/c)^3] If this is true, there is a thirdroot (real or complex).
Also you can avoid calculating a big square [b^2] such as 257^2 with an indirect approach:
[b]: number which square is hard to calculate
[a]: " " " isn't that complex to calculate
[c]: difference between them; c=b-a
b^2=a^2+2ac+c^2
Example: 257^2
b=257
a=250
c=257-250=7
257^2=250^2+2*250*7+7^2
[257^2=62500+3500+49=66049]
Post more tricks, so we can better our understanding of simple math problems with more different approachs.

this might be way too easy for the average /sci/ user but something I learned recently which helps is:
x^(17/40) = 5
x = 5^(40/17)
you can find the fraction of a number through a decent calculator
>>
>>8481467
This is primordial though.
I'm trying to understand how did the guy who made the quadratic formula thought. I don't know if there is a third grade polynomial formula, it probably is useless, though.

Just solve x from ax^2 + bx + c = 0

How can I understand probability? I feel completely retarded.
I understood the basics, but i stopped understanding altogether when we started doing Bayest, Binomiale, Poisson and Normal law. Is there some book or website that will help me understand? Pls /sci/ I want to study genetics and I won't get very far if I don't understand probability laws

Time to panic.
>For many years, scientists have been scrutinizing the cosmos for antigravity, who do not know if it exists but who insist on being called" dark energy. "But the rarest of all is the quantum Zeno effect, a theory that states That, by just looking at the particles, we change them (or rather, we change the level at which they decompose).
>A well-known scientist, Professor Lawrence Krauss, proposed a theory according to which the simple observation of the dark energy can cause its destruction, which in turn would cause the destruction of our Universe.
>Krauss believes that the result will soon come, especially given that in the late 1990s, when scientists were lucky to detect dark energy, a series of supernova explosions were observed.
Opinions?
