We should be able to solve this.
We play against /k/ today at 2:40pm EST/ 7:40 UTC, /mu/ on Sunday at 3:20pm EST/ 8:20 UTC, and /gd/ next Saturday at 2:40pm EST/ 7:40 UTC
If we do well enough in the group stage we go onto the knockouts and secure our place in this summer's cup.

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.
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?

I thought being able to get knowledge for free, at least cheap, was widely known. College students really are a special bunch.

Something has to change. The educated class is not being treated with the respect they deserve.
Do you want to live in a society that doesn’t appreciate education?

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.

>“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.”
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 don't think anyone on this board is clever enough to figure it out, but its a fun one.

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)

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.

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).

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?
But especially using vector lines or whatever to note and calculate and then mark the right position to be to do a certain motion?
but what I mean is that the fundamental strength of the force itself, changes depending on what scale you see it
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.

>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.

I came up with this problem myself for recreational math and when I tried to solve it I had no idea how. Basically, I put an equilateral triangle inside of a regular pentagon. The known angles are in picrel in degrees.

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.

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

>It is my belief that in the next decade and in the next century the technical advances forged by category theorists will be of value to dialectical philosophy, lending precise form with disputable mathematical models to ancient philosophical distinctions such as general vs. particular, objective vs. subjective, being vs. becoming, space vs. quantity, equality vs. difference, quantitative vs. qualitative etc. In turn the explicit attention by mathematicians to such philosophical questions is necessary to achieve the goal of making mathematics (and hence other sciences) more widely learnable and useable.

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.
