Person A lists ten cards and selects one;

Hearts: 5, 6 and 9
Diamond: 7 and 8
Spade: 4 and 6
Club: 4, 5 and 7

Person B says: "I don't which card person A chose, and I know person C doesn't know either"

Person C says: "At first I didn't know which card A chose, but now I do"

Person B says: "Then so do I"

The solution is Spade 6, but I don't understand how to get there.
Mathematically that solution isn't the only right one. Unless there's some word riddle which idk
You forgot to mention the part where A tells B the suit and C the number.

So, B knows it's spades, and he sees that C must have been told either 4 or 6. There's also a 6 in hearts and a 4 in clubs, so therefore B knows that C cannot possibly have enough information to deduce the suit, which he could have done with a unique number.
C knows it's a 6, so he knows the suit is either hearts or spades. But after B makes his statement, C knows that hearts is disqualified, because it has a unique number (9), so if it had been hearts, then B might have suspected that C already knew the correct card and kept his mouth shut. So now C knows it's 6 of spades, and says as much.
Then B, knowing that C now has enough information to deduce the right card, knows it cannot be the 4 of spades, because if C had been told 4, he still would not have known the answer, since it could have been clubs.
Ah yes, so working backwards, if we don't know the right answer, then you know after B's statement that there are no unique numbers in the suit, eliminating hearts and diamonds; after C's statement you know that the number must be unique among the remaining suits, eliminating 4; and finally after B's second statement, you know that it must have been a suit with only one option other than 4, which means spades with 6.

check 2017, virologists were studying SARS using CRISPR-Cas9 on Baidu
you are just an unbelievable fancy morron
A profound significance draped in ironic mundanity, meticulously constructed on a foundation of flaw, and veiled by a thin shroud of pure depravity.

is this the common sense of your failing mind
I don't care what contradicting studies say, I still think coivd was caused by biolab jannies selling animal carcasses to wet markets for easy side cash. This is a documented issue and I simply cannot believe a chinese biolab janny would never, ever mistake a control carcass for an infected one.

I found this link, but I cannot open it.

By the way, regarding SARS from 2002 to 2024, Chinese labs have been working on this virus for more than 15 years because it has caused significant losses in pig and horse populations. Instead of simply isolating one strain of the virus and relocating citizens and animals from affected areas, they continuously capture bats to conduct the same experiments again.

The genome has been scanned up to 98.6%, and they have a clear understanding of how COVID-19 operates. They also mention a pandemic virus X or COVID and refer to CRISPR-Cas9 as the "knife of God" or the "scissors of life" and other cult-like names. They use CRISPR-Cas9 for genome editing on various organisms, including chickens, pigs, babies, and even fish.

They mention numerous prominent individuals and give medals for nearly identical results, which I find uninteresting. I've checked many Chinese websites and concluded that they focus too much on experimenting with bats, which has led to the virus becoming more infectious and causing 800 victims in 2002 to spread worldwide.

Even now, they are primarily focused on stopping the virus rather than sharing their discoveries and informing the public. In my opinion, it would be better for China to seek worldwide help and be supervised because it's definitely unacceptable.

Even using CRISPR-Cas9 on rice, water, and other websites, their aim with CRISPR-Cas9 seems to be enhancing intelligence and altering genomes to make people appear more attractive on worldwide scale.

When I mention CRISPR-Cas9, I believe they are abusing it and using it as a tool to fulfill any wish, like a new toy for kids.

Why and how is the speed. of light constant?
Where does it get extra kinetic energy from? And how does it lose it? How does the light know how fast I am going and then adjust accordingly to go faster?

so between them being emitted and them being absorbed, they don't travel at light speed?
>light speed
what the fuck does this even mean? Everything has speed it has at any reference frame, and it's not constant, there's no magic here
>what the fuck does this even mean?
299,792,458 meters per second
yes this is not the speed of light inside of glass
nope it slows down.

we would see different speeds for each photon if it was due to collisions.

Why is time dilation a thing? Why can't we live in a universe where all events happen in equal intervals for all observers? Regardless of reference frame? Is there an explanation for this? It is confusing and retarded desu

>But moving at high energies (high mass or speed) slows time down not speed it up?
Only for the thing moving at a high speed relative to other things
>Almost like the processor of the universe is slowing down when having to deal with tons of interactions locally.
No, just no, look at the gif again if you are confused.
with gravitational time dilation you can think about it like spacetime being compressed which causes things to go slower. Time is pretty much running at different rates all over the universe, but there's still only one timeline. Time dilation from velocity is less intuitive I think, but at a basic level, if you think about how light is the fastest speed possible and is constant, and light does not experience time, so as you go faster you gets closer to the speed of light and something has to give and it can't be light because it's constant, so you start slowing down instead. Really we don't know if light doesn't experience time, but that is one of the required assumptions that allow the math to end up being correct
or the speed of light could just be a speed limit, and not the speed limit.
we do live in that universe

what makes you think we dont?
>Why can't we live in a universe where all events happen in equal intervals for all observers?
We might, however we have no way of measuring the "real" time or distances. Every measurement of "space" or "time" either directly or indirectly uses the speed of light as a ruler, so if light travels at a fixed speed, then time dilation is inevitable, regardless of what the true nature of reality is.
Relativity is just a numerical model, not metaphysics.

From what I understand the faster an object moves the slower it experiences the effects of time in comparison to an object with a lower velocity.
I call bullshit.
If, in picrel, both rockets have same quantity of radioactive material that decays over an unspecified half life and the red and blue rocket leave point A same time and arrive at point B at the same time. Your telling me, that blue will have more of the original radioactive material, because...? Even though both rockets moved between two points at the same time. Nah

Incomplete sentence
Study Einstein's personal life.
It's a scam theory made up by a patent clerk Jew who inbreeds to keep the bloodline pure, like Darwin also a jew.
Who doesn't even do experiments, who likes to talk with his lying mouth and plagiarize aryan men's discoveries and turn them into atheist indoctrination mayerials. Whose aim is to undermine people's belief in God and take away the divine seed of belief in children's heart.

So yeah, relativity can never be proved and is never applicable because you can't reach light speed, which is the whole point of this scam, to not be proven false.

>muh flying clock muh satellites
It's so costly to prove to be true by the folk.
Then think of it as length dilation. The results are identical, just worse for science fiction.
it's also convenient that none of triangulation algorithms break by "time dilation", because gps time is synchronized to satellite at all times... It's almost like it's not real
The only frame of reference that makes sense is one where photons don't move but propagate in the shape of a perfect sphere. In that frame of reference the one-way speed of light is constant. Special Relativity only cares about the two-way speed of light and the one-way speed is different for different observers. The preferred frame of reference makes calculations a lot easier when dealing with several points with different speeds. Relative spacetime is an illusion, spacetime is absolute.

>The fact that AGI hasn't been achieved even with these massive trained models and decades of research indicates that we're missing something very fundamental about the nature of what AI and what it can accomplish.

I think you've finally figured it out anon! All the engineers, computer scientists, and AI researches at the top universities and tech corporations in the world have it all wrong! Some of the smartest mind in the worlds have spent decades studying these topics, and yet they've all somehow failed to notice their mistake. Thankfully, a young right wing conspiracy theorist on 4chan has it all figured out: they've been doing it wrong the whole time. Now if only those woke leftist academics and the globalist tech corporations would put aside their hubris and recognize the ingenuity of our 4chan conspiracy theorist, then everything would be solved.

Schizos and anti-science/anti-tech losers can shit on AI all they want, but the progress in recent years has been fantastic. If you choose to ignore AI you do so at your own risk, and you'll probably find yourself in a similar situation to coal miners and other blue collar workers in obsolete industries who refuse to update their skills or seek out new training in AI, tech, or other scientistif fields that are going to be the future of a modern global economy.

That's in decimal system. You can write X.1/3 too but harder to calculate.

i was thinking more in the terms of what kind of geometry would allow you to generate such a field. im not sure if that explains my question well enough, so consider the pic in the op, here there are two parallel plates that generate the field. so is it possible for other shapes to make such a field?
