I never heard a of a young and healthy person suffering from long covid or any long lasting damage from the virus irl. I heard stories of people getting injured and one even dying from the vaccine in real life but they were also around 40 and above. I checked the news and the kids who are getting long covid are most likely vax maxxed by their parents

🧵 New Calculus
Anonymous at Wed, 1 May 2024 18:17:26 UTC No. 16155139
I recently got this guy who says that he invented a new rigorous formulation of calculus in my recommendation.
He says that the limit should not be in the definition of a derivative and that mainstream academia is being ignorant
His posts are occasionally extremely funny
But do his ideas have any merit?

🧵 Sleep Walking Medications
Anonymous at Wed, 1 May 2024 17:34:27 UTC No. 16155106
Which hypnotic medications causes sleep walking? I've had an anon on /fit/ tell me that all of them do. Ambien will definitely make you sleep walk (and do batshit insane shit while doing so), and lunesta will also make you sleep walk. A lot of unrelated sleep medications will also apparently make you sleep walk, like belsomra; although I find this highly unlikely. GHB is known for literally knocking people out. People will literally pass out in the middle of standing and just fucking drop if they take enough of it. There's a reason why it's such a popular date rape drug. I find it unlikely that this hypnotic would cause anyone to sleep walk. It essentially turns you into a stone at a high enough dose (3.5 ml or higher).
🧵 Going from a photon flux to a photon flux after a slit (partial photon flux)
Anonymous at Wed, 1 May 2024 17:23:43 UTC No. 16155097
Thanks to the help of an anon (who referred me to the Jackson textbook) and others a few weeks ago, I have managed to express the flux of a bending magnet like so:
[math]\frac{d_N}{\frac{d\omega}{\om
this is expressed in the units of [math]photons/second/0.1\%bw[\math]
With a little python script, I can graph this as a function of the energy. To verify that the equation and code is correct I compare it with spectra (synchrotron sources software).
I end up with the same flux they do. All is good. I have normalised the fluxes.
See pic related.
When I select with Spectra the option partial flux which gives the user the option of adding a slit of a certain size at a certain distance from the source, I end up with a different flux (called partial photon flux).
First, I do not understand this.
I have both the angular divergence and the size of my beam at point 0(horizontal and vertical).
[math]beamsizeatD = 2*D*\tan \frac{\sigma'}{2}[\math] where D is the distance to the source and [math]\sigma'[\math] is the angular divergence (horizontal or vertical), I see that the beam should be smaller than the slit, therefore the slit shouldn't have an impact yet it does.
And even when I take into account the size of the beam [math]\sigma[\math] at point 0:
[math]\sigma + 2*D*\tan \frac{\sigma'}{2}[\math]
it's still smaller than the slit.

🧵 life after death
Anonymous at Wed, 1 May 2024 16:40:55 UTC No. 16155047
this is what they have figured out so far about human brains after time of death
https://www.tivi.fi/uutiset/tv/e614
Theta waves almost stop after death, gamma waves increase.
Thetas are 3.3 Hz and Gammas are 44 Hz.
Gamma waves are thought of being utilized for consciousness. Thats peculiar if a dead brain is having a consciousness.
Altough doctors cant say for certain Gamma waves are linked to consciousness, thats the best guess according to all the data so far.
Four patients brain waves were measured immediately after they had died for the purposes of figuring out what happens next. Their brains were in good shape right from the start but their hearts gave up. It wouldnt make sense to measure brain dead person who has a good heart, only the opposite.
Out of these four two had rapid increase of gamma waves some minutes after death.
The doctor wrote: "we cant say for sure what these people were experiencing because they arent here telling about it"
People who "almost died" have returned to tell how they floated above their bodies and watched it die but then they were pulled back at the last moment.
But we just dont know if people who really die, have this same out of body experience. They havent returned to tell about it.

Is Kolmogorov's axiomatization of the concept of probability a physical theory?
What's a list of the physical theories?
1) General relativity spacetime with Newton laws and fields like the electromagnetic ones
2) Quantum field theory(s)
Then statistics applied to it (itself making use of Kolmogorov), which justifies but doesn't necessarily give all the models of
3) Thermodynamics
That all?

since time dilation is (probably) a thing, so if humanity discovers FTL travel and decides, as a collective, to take a trip in outer space and leave the trees and animals and flowers and shit the fuck alone, wouldn't nature get more me-time from its own time perspective in our absence?

Alright this is kind of weird, but what would make non-local FTL impossible? If everybody lived really deep in a gravity well, then had explorers flying around at relativistic speeds to get time dilated and returning, from their perspective they could explore N light years away in way less than N "home years". I get that we don't live in an insanely time dilated situation like the time dilated bros, so you can say FTL like this is impossible for civilizations at "a normal amount of time dilation" - but then you kind of need to define what a "normal amount" which contradicts reference frames never being privileged

because energy in a system is not constant
This is the real model of particle physics:
Three variables:
>energy
>charge
>anti-charge
Behaviors of ()charge:
>it always tries to bind with X-amount of energy which a standard of the universe's creation
>on collision it cancels out with its opposite of the same magnitude
>adds to its own kind when unbound on collision
>when bound repels its own kind
Manifestations of energy:
>matter, energy taken form
>kinetic energy, how much a particle is disturbed
>heat, kinetic waste on collisions, it disturbs a particle via excitation on collision
The making of hadrons:
>()charge keeps encountering its kind unbound for a while and bloats up
>it finally encounters a particle bound to the opposite kind
>it eats up that ()charge and binds to the particle
>does this with other particles and they will share this blob of ()charge, alll touching it like blocks on the stakataka pokemon
Formation of an atomic nuclei:
when hadrons of opposite charges encounter they will bind together, because the charges cant touch each other they cant cancel out but still pull each other close
because the above composition will never be perfect it keeps looking for orbiters to get its charge to 0 or its mass to the perfect ratio
the orbiters are not strictly bound so atoms can exchange them.
atoms can also exchange hadrons, freeing ()charge seems quite hard.
