How much sleep do you need?
sleep is for pussies
I've been on a Everyman polyphasic sleep cycle for nearly 9 months until July.
That's 3 hours of sleep per night and 3 naps during the day, each 20 minutes long.
With these cycles, you are basically maximizing REM sleep, while minimizing sleep altogether.
>>8397533
Any side-effects? I tried some years ago but after some time waking up from the naps was a pain, I don't like sleeping a lot
How do I go about scientifically proving that pills are making me stupider? I was taking Citalopram which wasn't bad then Cymbalta. and now because of Psychosis I'm taking 15mg of this shit. Small dosage but still feeling like a brainlet.
I'll take my delusions back if it means I can be bright again.

look up one of the hundreds of studies already done on the negative effect of antipsychotics on cognition
its already been proven, theres nothing further to discuss

give it time to work. It does fucking miracles and eventually you will be better off.
It helped my schizo cousin too, he actually seems pretty normal now, which is fucking astounding. Just give it time.
There was a post here a couple of days ago that REALLY made me think
If the Big Bang actually occurred, how did matter and energy expand in the first several minutes of existence even if it had the combined gravitational pull of the entire energy content of the Universe stuffed in a single spot?
Even weirder, how come space and time wasn't warped to infinity due to the immense gravitational pull, rendering movement (and time progression) physically impossible?
That one's easy. Because gravity, space, and time didn't exist at the time of the Big Bang. In fact, the laws of phyics didn't appear until the BB was well underway (that is, after a few zillionths of a second, not several minutes.
>>8397240
"How long" did it take before the big bang happened.
Is that even something that can me measured in terms of "years"
How do you figure it out
>>8397245
You get a PhD in astrophysics.
Since homosexuality is a genetic trait then by following natural selection and sexual selection does that mean the homosexual gene would go extinct soon?
Homosexuality existed a long time ago but they still haven't died down.
I know that most homosexuals, who happen to be bisexuals, can still have an offspring and spread the genetic trait but the their chances on doing it is quite small.
Any thoughts on this idea?
no, people turn gay all the time when they go to prison
The genes causing homosexuality have an ESS that keeps it at about 5%.

Wouldn't our genes evolve into something else that would stop this?

Quite some theory I've been pondering as of late. How exactly does this work? Can anyone brainstorm with me and help me explain this truly captivating phenomenon?

Is there any scientific evidence to support the theory of The Butterfly Effect where hypothetically if a Butterfly were to fart or whatever in New Mexico it could cause a typhoon in Japan?
>>8396778
>it's impossible to predict what caused a typhoon
>blame the butterflies
>dindu nuffin
>>8396778
Yes and no.
The "Butterfly Effect" in and of itself, is intended to be an exaggeration describing the general idea of chaotic systems (better referred to as "nonlinear systems"). The idea is that infinitely small changes in input can cause huge changes in output. This doesn't happen in linear systems. A little change in input, a little change in output, y = mx + b and all that fun stuff. But in nonlinear systems, and impossibly small change can give you a completely different result.
As an example actually dealing with the weather, let's suppose that meteorologists have a grid of probes spaced one meter apart, covering the entire surface of the earth, from the ground up to 100km high, and have probes also regularly spaced through the ocean, providing them any kind of data they could want about that point. Let's also be generous, and give them infinitely precise data. At a given moment, all of the probes take their measurements simultaneously, and the information is fed into an infinitely powerful supercomputer used to simulate future weather.
Within one month, the simulation will be completely out of touch with reality. Even with this impossible amount of data and computing power, the small variations in temperature, pressure, wind, sunlight in between the probes is enough to completely change the outcome of the system.
If you're curious, also look into bifurication of functions. Part of the idea is that certain functions are particularly prone to this around certain values, and so an extremely small push can push an otherwise normal-seeming function to completely change results.
Another example would be a metal pendulum, in the center of a triangle with a strong magnet at each point, spaced equally far away. The borders of the regions of attraction between the magnets regress into infinitely deep fractals, so that if you place the pendulum directly between two magnets, in real life you'll never really be able to predict which one it falls into.
I think this shit should just fall under chaos theory, if a typhoon could be caused by a negligible puff of air then it should follow that a typhoon could be caused by a lot of things
I know v(t) is vector value and |v(t)| is a "scalar" but exactly is the difference in applied physics?
If v(t) = 3t+5
then v(1) = 8 m/s and |v(t)| = ~6 m/s
what's going on?
>>8396742
A scalar has one property, magnitude. I am moving at 100 miles per hours, i could be in a rocket headed out of earth's orbit, in a car on the freeway, in a submarine going underwater, etc. Inherently in a scalar definition there is no direction defined.
A vector on the other hand has a magnitude and specific direction.
In math terms the absolute value is useful for things moving in one dimension, forward or backwards. A magnitude of 6 doesnt say away from the starting point or towards it, but a vector does define what direction is being traveled.
>>8396742
v (t) has an implied direction. Usually this is denoted by ijk or xyz with hats for vector and dots for scalar but often omitted.
Also, a scalar has no units.
Could it be possible for us to be inside a simulation?
Could it be possible for OP to not make shit threads?

yes, but would it really change anything for you, if you found out for sure?
Hi /sci/
/lit/ here
I am writing a story that includes a character who is mathematically literate and also sort of a pretentious dickface.
I need a branch of mathematics that is two words max and is extremely high level. Like, only a math PhD would have mastered it. The character would say to someone he's angry with "this isn't fucking (whatever) (whatever)!"
I want it to roll off the tongue well in such a situation
>>8396717
Holy FUCK did you come to the right board! Why don't you just go with "Science & Math?" It pretty much screams pretentious dickface.

Is this a valid interpretation of the photon split experiment?
This is really spooky.
>>8396707

Is this the big toe guy?
>>8396741
Yes, is he legit? I can't find his academic credentials. He works at NASA as a consultant, but it's probably nothing in the field of quantum physics.
Is there any other evidence for the acceleration of the expansion of the universe other than the exponential relationship between redshift and distance?
Is it possible that space is simply consistently attenuating photons over time? The resulting energy gets then lost as dark energy or whatever.
>>8396660
Was having similar thoughts:
What if the big bang isn't real?
Could it be possible that the universe just seems to become smaller/hotter when you look far back in time?
Maybe the universe has been going on like this for ever, but we stuck with that strange theory.
Tbqh i find the big bang hard to believe.

Can someone help explain what base reality might be and its possible origins?
>>8396605
I mean, I guess in the context you heard it, "base reality" means a reality which is not a simulation of something else. For instance, and I hate to keep going back to these movies, in the Matrix, the world ruled by machines it the "base reality" and the Matrix is a simulation of it with different parameters (namely it's not run by robots).
What do you mean by possible origins? Like where does the term "base reality" come from? It's literally just the combination of the words "base" and "reality," where base means something like "root" or "main" or "supporting structure". And reality means whatever you'd like it to.
If you mean, "assuming this world is not base reality, where did the actual base reality come from?" then there is no possible way to answer this question scientifically, as we have no way currently of collecting data from the "base reality" that we know of.
>>8396619
Yes I am implying that we can accurately determine, sometime in the future (soon) that we exist in a simulation.
What does that imply about the characteristics of so called base reality? What could it possible be
