I was just on /b/ and some op was going to give out a vid of him fingering his classmate if someone got quads. So given the posts per whatever unit of time suits your fancy (there has to be statistic out there somewhere), what is the probability of a get?

I honestly couldn't come up with a more trivial probability question than this.

Well let me try:
>There is a house with 10 children and two are male. If you pic a random child, what's the probability that this kid is male?

You can answer your question exactly like the above one.
>>
obviously quads are gotten every 1111 posts (not including 0000 which happens immediately after a 9999) but you're assuming all post numbers belong to a single thread, which they don't, so you can't reasonably calculate how long before a single thread gets quads

So I was thinking, as I tend to do, when I realized something. If we sent a satellite probe out into space at 1/2 the speed of light, then in 2 years, it would be one light-year away. But, if it's one light year away, then it would take us a year to see it there, and by then it would have traveled a whole 'nother 1/2 light-year. So, I made a simple equation for figuring it out:
X = Y + (Y x Z)
X = Distance object actually is.
Y = Distance object appears to be.
Z = How fast the object is going, where 1 equals the speed of light, and .5 would equal half the speed of light.
Is my math sound, or am I just retarded?

Seems very likely. Especially considering how mechanical engineering doesn't require as much maths as physics does. At the same time, people who study a degree because they enjoy the material rather than because it gets them jobs (i.e. typical physicist vs typical engineer) are probably going to put the effort into learning the material.

My favorite physics professor always had rants about engineers' incompetence in math.
Here's a video about such an occasion:
https://youtu.be/nGUpVIg3e8E
Although it's in Hungarian, his gestures are pretty universal. At 0:40 ha asked people to raise hands if they could calculate the eigenvectors of a 2x2 matrix. Few people raised their hands, and then he went into rant mode about the lack of basic math education, the whole higher education system and then drew some parallels with politics aswell. Based sperg teacher.

Hey /sci/.
Jokes aside, what are the chances of a major happening occuring in our lifetimes? By that, I mean things like very destructive wars, terrorists/rogue states using WMDs, major tensions between world powers, and such.

I read a lot of think tank and statistical reports on the topic, but there seems to be no consensus.

Jokes aside, none. Only "happenings" will be in the Middle East or Turkey-Kurd civil war (which is already underway in some ways). Dictators are those who change the course of history significantly. Terrorist attacks are irrelevant and forgotten in the long-term. Turkey and China will be the source of any increasing tensions in the coming years, but there will be no major happening as /pol/ always "predicts" (in our lifetimes at least). The world is ruled by plutocracy now, and war/conflict is not at the top of the priority list.

Geopolitics has a wide range of meanings. You might want to narrow down the point you're trying to make?

As for the picture, ideologies/Royal feuds are anachronistic notions nowadays, in the wake of the 2 World Wars that reminded us how bad things can get. We're far away from that path.

>dual-slit experiment
I feel that this thing is interpreted by these pseudoscientists wrongly. (no shit)

I'm tired of hearing that particles "know" when we are observing them so they decide to act diffrently.

How can observer affect what happens at the end of experiment just by looking at it?

What is the counter argument to this claim?

Can't find a thread about this

http://www.sciencealert.com/stephen-hawking-has-finally-published-his-solution-to-the-black-hole-information-paradox

>The problem is that, according to Hawking's best calculations, that (hawking) radiation would contain no useful information about what the black hole ate - the information swallowed up would have been lost forever. And that doesn't gel with our understanding of modern physics, which states that it's always possible to reverse time. In theory, at least, processes in the Universe will look the same if they're running forwards or backwards.

>But Hawking thinks he finally has a solution to the problem - black holes might actually have a halo of 'soft hair' surrounding them, which are capable of storing information.

>That 'hair' isn't actually hair - as you might have already assumed - but is actually low-energy quantum excitations that carry with them a signature pattern of everything that's been swallowed up by the black hole, long after it evaporates.

>But he admits: "It is certainly possible that, following the path indicated by this work, further investigation will uncover more hair of this type, and perhaps eventually lead to a resolution of the black hole information problem."

Thoughts?

Unless someone programs them to kill us all they won't. Nice thing about computers (Even hypothetical intelligent ones) is that they have no biological or social drive, all they exist to do is what they are told to. Now if someone set up a malevolent AI with the goals and tools to destroy us, then we'll probably all die in about 2 hours once it finds a way to remotely access nuclear weapons.
My advice: Don't worry about it, they won't do it on their own, and if someone programs them to do it there was very little anyone could do about it, and after we're all dead none of this will matter.
>>
>>8128826

>inb4: someone post the flowchart from that SJW place called SMBC comics which compares the idea of an AI with or without ethics.

Unless someone wants to kill itself... no I think not, AIs work around strict lines and they can be deactivated in case of bugging out, and even in case of bugging out there are somethings that just can't do: For example; Mimic the president to order a full nuclear attack(nuclear silos work in isolation with very old equipment to avoid this kind of things)

The job is science is the explain how the universe works. How is it not a science problem if science can't explain subjective experience? Do you deny its existence?

>2) most people here dismiss it by presuming it's just an emergent property of the brain and then acting like it's a solved problem
That's not very scientific. That sounds a lot like something a religious person would say.

(nsp: not same person)

The job of science is to postulate theories which can be falsified by experimentation. Do you want science to solve Human Consciousness? Then let scientists grow vat babies and cut into their soft little skulls; in fact give me about 100,000 donor eggs and 3 decades and i'll tell you what it is to be man.

The job of philosophy and mathematics is to construct a rigorous argument giving a beautiful and simple solution to a previously intractable problem in a very abstract environment where methods and techniques used to obtain the solution may be ported back into our real world and be used to solve something meaningful.

Do not confuse Mathematics and Philosophy with Science. Mathematics is the art of problem solving, Philosophy is the art of natural language (or asking questions). Science is the method of reliably predicting the outcome of something, it's an approximate guess.

To your question. My thought is that consciousness is like a girl sitting on your face, even after you pay her to leave there's a little bit left of her on you. There is an echo of her sitting on your face. You keep repeating it to yourself and distorting the echo and then eventually another girl replaces her, replete with new echoes and new repetitions and new girls and so on.

At the end you are finite, you will have had your face sat on so many times, and all you are left with is the impression of a hundred sweaty wet vaginas mushed up against your mouth and nose.

>Chalmers' formulation
>Why should physical processing give rise to a rich inner life at all?

Because if you're some Oxbridge needledick with 50,000 words you're bound to over-indulge in language and under-indulge in living. We do what we are trained to do, we are impressionable robots,

If you are young and want into science why don't you follow the way of one of the most intelligent people ever?

Look at Alexander Grothendieck. He wrote how much loneliness is important. Secondly, he ended his life as a recluse, some kind of monk. And if you are fedora I have sad news for you, he believed in the Devil.

I do not know if he was having a lot of sex but he has a son. But then again he could be a cuck...

But was he really intelligent? Isn't life all about pleasure and comfort? Was he rich and did he fuck a lot of qt \pi s?

Let [math]X[/math] be the set of sets that don't contain themselves.
Does [math]X[/math] contain itself?
This is Russell's paradox stemming from Cantor's infinite sets. The answer would be both yes and no. This is beyond the comprehension of people who believe in the law of excluded middle.

What if we adopted a quaternary logic instead of a binary logic? The possible answers would be:

-yes
-no
-both
-neither

is quaternary logic the answer to everything?
