Materialists are /x/ tier shizos
97278
Somehow someway, you think you will get subjective experience suddenly appearing out of non-conscious matter? That is magical thinking. That is /x/ tier.

There is no way to deduce subjective experience from something that is fundamentally not experiential.

It's not just a hard problem. This is an impossible problem with magical thinking to mask how stupid it sounds.

losing passion
done
I used to have a passion for mathematics, but my PhD experience was traumatizing. My advisor gave me poor advice that led to the failure of my research project, and my research papers were criticized and rejected by nearly everyone except my advisor who claimed to have a very positive opinion of his topic. One professor even told me to my face that I should have known better than to work on this project. The aftermath of my PhD made it difficult for me to find employment in mathematics and resulted in financial loss for my family. My mental health was severely impacted.

Recently, my advisor hinted that he may have been incorrect in his assessment of my project, and that I had potential as a student. However, this only fuels my bitterness. Some people tell me to get over it and move on, but I find it hard to move past my trauma and rekindle my love for math.

Is it justified to have an aversion towards a subject due to a traumatic experience?

Ai will replace high demand high salary jobs, especially those that change rapidly like medicine and law. It’s much easier to make a patch update to lawyerbot1.1734.02 whenever a new law is passed than it is to retrain hundreds of thousands of lawyers. Same with basic medicine. Overall this will lead to a faster change-to-perceived-change time, and also limit the ways lower class can move into the upper class. Absolutely will increase government centralization.

What is the ultimate goal of science or our use of the scientific method? What is the purpose in all of this? If science tells us that we will all die with no afterlife and that the Earth and Sun will be destroyed an ultimately the universe will become incapable of containing consciousness and thought and that there is no meaning or purpose in any of this, then why bother? Why seek knowledge and truth without purpose, and that will ultimately be forgotten?

I always knew that vaxx was harmful, although I had no choice, I was in a very compromising situation at the time; holy crap I feel so stupid and weak right know.

SLEEP LEARNING

Why can't we remember things we hear while sleeping the same way we remember things hearing while awake?
Would it theoretically be possible with more research and development to ever create a device that stimulates the brain to memorise audio asleep similarly to when awake or would this interfere too much with the natural functions of sleep?
Seems like a bajillion dollar opportunity to give everyone 8 additional hours per day for learning.
Also sleep learning general in case you have something to share or discuss about that that my tard brain doesn't know about.

When I was a kid I often had this idea / thought experiment about color perception.

Consider two people looking at a red object. Their eyes perceive the light of a certain wave length and then this input is representet in their mind. Now what if the subjective internal representation of person A is the usual red but in person B it looks like the color blue subjectively looks to us? We could never know because both people are referring to it in language as "red", and person B wouldn't know that other people's red looks different from his blue red.

Does this make any sense? And has science solved this or done any research on this topic? Thanks in advance.

Persuasive messaging to increase COVID-19 vaccine uptake intentions
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8531257/
>“Viewing vaccination through the lens of a collective action problem suggests that in addition to increasing individuals’ intentions to receive a vaccine, effective public health messages would also increase people’s willingness to encourage those close to them to vaccinate and to hold negative judgments of those who do not vaccinate. By encouraging those close to them to vaccinate, people are both promoting compliance with social norms and increasing their own level of protection against the disease. Also, by judging those who do not vaccinate more negatively, they apply social pressure to others to promote cooperative behavior. This would be consistent with theories of cooperation, like indirect reciprocity or partner choice, that rely on free riders being punished or ostracized for their past actions to encourage prosocial outcomes. Thus, effective messaging could have outsized effects on promoting vaccination if it both causes people to vaccinate themselves and to encourage those around them to do so.”

Volity Theory
45895DA9-B08E-4F5F-A88F-1049E00DE4E0
(1/21/23)
Resolving Bell’s Inequality Paradox

Ψ^2/Ψ (Volity Theory)

Abstract: Quantum Nonlocality is currently viewed as the accepted orthodox description of how to explain the laboratory results of so-called “entangled particles” that violate the Bell inequality. This presentation provides a new theory and description of what is going on, and is able to arrive at the same calculations as traditional Quantum theory, but by using crude and basic mathematics that any person of average I.Q. can understand. The way that this is possible is by changing the paradigm of the description of the statistical results. The particles are seen to be Independent Events, and the more simple an explanation, the more likely it is to be closer to the truth of the description of reality. The new theory points in the direction of a possible Nonlocal Hidden Variable Theory. Finally, this theory proposes to serve as a possible bridge between the laboratory results and Einstein’s classically deterministic probability expectations.

After many various private calculations and versions of the same essential concepts, it is believed that the Probability differences in Bell’s Inequality can be accounted for in relation to the results in the laboratory.

We will take a look at one version of the Entanglement test. See attached photo.

I have a hypothesis. I think bandaging small wounds makes you more prone to flu and viruses. I think when you explose the epidermis and capitalary bloodstreem to external particles, there is a better defense than in a deeper wound directly into the bloodstream. I hypothesise that more antibodies are created when exposed to very light cuts and wounds.

I say this because i never bandage or wash small wounds. I not only just lick them, but I am constantly peeling the scabs away and licking the bloody wound. In the past 6 years I havent been sick except once a few months ago when i entered the house of a person who had died and been stewing for 5 days, and it only lasted a week. My wound antibody methods didnt protect me because the products of human decay was a new pathogen.

So, my question to you is:
-How often do you let small but bleeding wounds go without bandages (whether accidental or intentional self harm)
-How often are yo sick and the last time you were. (Feel free to discuss past few times and what your ailments were)

1671985230054313
So I got in an argument with a girl who I have a crush on about the covid-19 vaccines. She made some dumb statements about the vaccine. She thinks there are roughly 1 in 800 excess serious events among the vaccinated cohort of the Pfizer trials. She is quoting this. https://www.sciencedirect.com/science/article/pii/S0264410X22010283

Then she is saying that this 'new data' shows that young people didn't even need a vaccine because we were never at risk, and that we 'ruined the world' for old people. See data here.
https://www.sciencedirect.com/science/article/pii/S001393512201982X

I need arguments guys. She is mocking me and implying I am impotent and braindamaged from the vaccine. Most of our friend group caught the virus and I'm the only one who caught it twice, while every vaccinated person caught it, apparently the unvaccinated retards didn't even have symptoms (she is unvaccinated and talking about finding an anti-vax bf).

Anyway how do I win this argument? These studies are trash, right?

There was a source of radiation lost on a Western Australian highway.
https://www.abc.net.au/news/2023-01-28/radioactive-capsule-search-perth-to-pilbara-/101902914

Is there a feasible way to detect isolated radiation sources from multi-spectral sensors?
Obviously there is a few limiting factors.
>resolution
>wavelength operating range
>exposure time required for likely capture
>sensor type
>physical location of the source being exposed to open sky

I haven't had to access satellite data for a decade, so I wouldn't even know where to begin to look.
But if it was theoretically possible for the sensors to actually detect it, then it should be a very trivial process to isolate it.

I'm ok with the data processing side of it all, but I'm not sure what sensors (if there are any) would be able to detect it.

Thoughts?

So given a single rig (marked yellow) and a set of frames to fill in to achieve a certain motion... how do you scientifically consider/diagram the factors needed to move each appendages(yellow lines) here to realistically do a particular motion, without doing mocap first. Like achieving a certain weigh or speed...

But especially using vector lines or whatever to note and calculate and then mark the right position to be to do a certain motion?

Electronic structure code share
martin
Calling all solid state physicists and chemists!

Despite much progress, the field of electronic structure is still plagued by proprietary licensed software. Access to the source code of these programs is the only way to understand both the theoretical background and advanced numerical techniques underlying these methods.

Some students are locked out of this due to the extortionate license fees demanded with profits usually not going to the contributes. Even those in well funded labs are disadvantaged by only having access to one or two of these proprietary codes and if they are focused on open source development and science it is likely they will not have any access at all.

If you are working with codes such as VASP, FHI-aims, Wien2k, Crystal, CASTEP or ONETEP or any other proprietary codes please post the source code or binaries here. Computational physics and chemistry codes from other fields are welcome too.

To start us off, here is an older copy of VASP from 2020 https://easyupload.io/la4ego (password: sci_code_share)

Look at a single point as if it was a house. What does it take to get from house to house? You need to walk, you need to spend energy.
It takes an increased and sustained amount of energy to keep these two houses connected. Like maintaining a road.
The act of moving from point to point is to create time.
The act of moving from line to line is to create time.
The act of moving from space to space is to create time.
Time can only be experienced.

Hegel explains where physics went wrong
hegel1
>At present, students of nature who are anxious to avoid metaphysics turn a favourable ear to Atomism. But it is not possible to escape metaphysics and cease to trace nature back to terms of thought, by throwing ourselves into the arms of Atomism. The atom, in fact, is itself a thought; and hence the theory which holds matter to consist of atoms is a metaphysical theory.

>Newton gave physics an express warning to beware of metaphysics, it is true, but to his honour be it said, he did not by any means obey his own warning. The only mere physicists are the animals: they alone do not think: while man is a thinking being and a born metaphysician. The real question is not whether we shall apply metaphysics, but whether our metaphysics are of the right kind: in other words, whether we are not, instead of the concrete logical Idea, adopting one-sided forms of thought, rigidly fixed by understanding, and making these the basis of our theoretical as well as our practical work. It is on this ground that one objects to the Atomic philosophy.

>The old Atomists viewed the world as a many, as their successors often do to this day. On chance they laid the task of collecting the atoms which float about in the void. But, after all, the nexus binding the many with one another is by no means a mere accident: as we have already remarked, the nexus founded on their very nature.

Climate change is over, pack it home boys
FnfF07LWYAA49rJ
Gates directed this year’s letter toward high school students, complete with personal details including his early affinity for Superman comic books, his bad grades in middle school and his love of Cocoa Puffs cereal. (Melinda Gates, who focused the second half of the letter on gender equality, prefers Wheat Chex). He punctuates his letter with a simple mathematical equation he concocted that underscores the need for what he calls an “energy miracle”.

P x S x E x C = CO2 (carbon dioxide output).

It’s a neat little formula because it drives home the point: that for all the Paris climate talks and more affordable Teslas, environmental incrementalism is somewhat pointless. In the equation, P = population; S = services used by people; E= the energy needed to power those services; and C equals the carbon dioxide created by that energy. Population is of course trending ever-higher, as are the services people demand, especially in the developing world which has barely scratched the surface in terms of cars and air conditioning and other modern basics. Those two factors swamp progress in energy efficiency. Gates points out that scientists are calling for an 80 percent drop in carbon emissions by 2050 (and a total end by 2100) to stave off the most dramatic effects of climate change, yet even with more efficiency, the growth in population and services means that emissions will instead jump by 50%.

Math 101: the only way to get to zero carbon dioxide output is to drop one of those inputs to zero. Since eliminating any carbon byproduct of energy is preferable to a complete human die-off or a stone age suite of services, that’s the only path. Shaving at the margins simply won’t get the job done; only a moonshot solution that provides unlimited clean energy will stave off environmental (and thus, economic) catastrophe.

Quantum Torsion
download (1)
This concept represents a field that is generated by the spin of subatomic particles, such as electrons and protons. This field is thought to be able to cause a twisting or torsion effect on space-time, similar to how a spinning top causes a twisting effect on the surface it's spinning on. The torsion field is thought to be able to affect the behavior of other subatomic particles, and potentially even macroscopic objects.

A possible equation to describe the effects of this field on a particle with spin s, in the presence of a quantum torsion field with strength T could be:
F_t = s * T

where:
F_t = force experienced by the particle due to the torsion field
s = spin of the particle
T = strength of the torsion field

The Box Paradox - does it prove earth has a physical container (firmament)
THE BOX PARADOX
>>33933526
Can someone here please explain the answer to this paradox for me:
https://youtu.be/dY6zDwir8VY

I have yet to hear ANY answer that can explain how this is possible according to our current understanding of “gravity” and the 2nd Law of Thermodynamics...

i have posted this many times in many different threads on other boards and i never once have heard an answer that isnt easily shown to be fallacious. ill post the most common answers ive gotten to this paradox in the replies to this thread below, and the refutations i have to them.

>The currently accepted model of earth claims that earth’s atmosphere is adjacent to the vacuum of space without a physical container separating them.

>The 2nd law of thermodynamics states that high pressure will immediately seek equilibrium with low pressure.

>The heliocentric model claims that “gravity” is the “container” that keeps the earth’s pressurized atmosphere from immediately seeking equilibrium with the vacuum of space.

>The “pressurized box of air in a vacuum” experiment proves that gravity is not capable of preventing earth’s atmosphere from seeking equilibrium when exposed to a vacuum.

>There is no altitude within or outside of earth’s atmosphere where you can perform the experiment and not have the air in the box immediately seek equilibrium with the vacuum chamber once the lid of the box is removed. Gravity NEVER holds the air in the box. Gravity never prevents the air from going into the vacuum.

>Gravity only has one vector - DOWN. So, if gravity is holding the entire atmosphere DOWN on earth; then it stands to reason that, in the box experiment, the air inside of a box on earth’s surface should be held DOWN and prevented from going UP and out of the box when the lid of the box is removed. The fact that the air inside of a box without a lid will move UP and into the vacuum chamber proves that earth's gravity is not strong enough to prevent it from going UP into the vacuum.
