shouldnt the guy on the pillar be rising toward the portal so he can have the momentum to fly out portal b
>>344854572
thats the bait.jpg
>>344854767
why not just have him fall straight down without the portals? fucking idiot
>>344854767
Gave me a chuckle
>>344854369
Ha
5/10 bait points for idea
>>344854767
That is so fucking
GENIOUS!
You mad scientist.
>>344854868
>i don't get sarcasm
do you even basic human interaction faggot
Both portals are underwater
There, done
>>344854572
>>344854654
>here we go again
But isn't it that speed is relative? I mean we're zooming in space at a 19 miles per Second, yet we tell ourselves we're not moving, when standing still.
In other words, if the portal comes down at a speed, isn't it the same? Relatively speaking the guy is moving towards the portal (or the portal moves towards the guy, doesn't matter).
So yes, he would have enough momentum to hit the spikes
>>344855106
Portals are just doorways. He doesn't have any speed, so he doesn't come out of the orange portal with momentum.
>>344855196
>Portals are just doorways
no
>>344855196
If they were just doorways, they would be called doorways and not portals
>>344855248
My mistake, they're physics defying doorways cut in half through science.
>>344855135
gee boris why did mom let you have FOUR PORTALS
>>344854767
Remove the portals and it would make zero difference. Fucking hell why is /v/ so stupid.
>>344855135
Is this Loss?
Can I work for Valve now?

I'm not fucking angry.
>>344855436
>>his speed is 0mp/h
no
>>344855526
Yes it is.
>>344855436
From the blue portal's perspective, the man is moving towards it. That speed will be conserved as he exits the orange portal.
>>344855546
>"it's a doorway"
XD
>>344854767
10/10
>>344855630
a portal is literally LITERALLY L I T E R A L L Y a doorway with its two sides in different places
A is exactly what would happen
>>344855630
>It's not a doorway
>>344855357
hes pulling onto himself and he eventually dies by decapitation and his body parts infinitely go through the portals
no you cannot work for valve for this terrible thought out idea
>>344855701
Then tell me this mister smart guy. How do you go through a door without moving?
>>344855106
Yes. Consider that the man in the diagram is standing on a moving surface (the Earth) and it becomes very obvious that he would fly out of the other side.
And if that doesn't convince you, consider that he'd be crushed if he emerged with no velocity, because he'd be emerging from the portal slower than he was entering it.
>>344855701
>>344855713
haha doorways sure can have an exit that moves relative to it's entry! That's a good one!
>>344855336
Lost
>>344855436
>Enter portal at a high rate, exit portal at a high rate.
>He enters the portal at the speed of the moving platform.
See >>344855546
The answer can't be B because the rate that the person exits the door changes. Same with the original problem where the person has to exit the portal at the same rate that they go in.
find a small object and a cardboard tube
slam one end of the tube over the object
does the object suddenly fly out the top? no? the same physics in theory would apply to portals
He has to SUCK his own DICK
>>344855610
>blue portal's perspective
I like how you fags literally just make shit up to explain how stupid you are.
The portals don't have a perspective, everything exists in one single reality with the same physics.
If they somehow had their own perspectives attached to them what the fuck do you think would happen when they're both located on a planet that rotates and moves 30 kilometers a second through space?
>>344855767
Kill yourself retard.
>>344855807
>the same physics in theory would apply to portals
nope
>>344855758
Make the doorway move towards you. Is this a question?
>portal
>a monumental gate or door
>>344855767
make the door telescopic. move one side but not another. task done. you still dumb boy.

>>344855813
Thanks for making up a new fetish for me.
>you will never be portal-dominated by Chell
>>344855834
You don't know how velocity or simple frame of reference logic works so stop using terms like "stupid" and "retard", child.
>>344855551
Wouldn't this just happen tho
>>344855884
You use the portal gun on moving surfaces in 2, you mong
>>344855856
Sure thing, then if you put your leg through the door your leg has velocity but not your body :^)
But you don't understand this.
>>344855912
>Now you're dominating with portals!
>>344855884
Play Portal 2 again.
Open at your own risk.
>>344855701
Portals cannot work in real life exactly because they break the law of relativity of velocity. If the doorway comes at you with 50km/h then it's the same from the doorway's position as if it stands still and you have the 50 km/h velocity.
And so you have on one hand a doorway like entry that should pass over you unaffected abd on the other that your relative velocity cannot suddenly become 0.
>>344855834
>the portals don't have a perspective
>everything exists in one single reality with the same physics
No, that's not how physics works
>>344855837
This is a black and blue white and gold scenario dude some people's brains just can't fucking work properly and need to be gassed.
People who think a portal moving towards you as you stand still would launch you are either trolls or mentally handicapped
>>34485591
>>344856037
With opposing portals like this, according to the game it would be functionally identical to simply step through a hole.
Now tell me what would happen in your world where both portals have their own momentum in opposing directions because of the rotation and speed of the Earth.
kinda relevant tbqh
What happens /v/?
>>344855834
/v/ didnt make up relativity retard. Assuming that the portal is moving at a constant velocity it has its own frame
>>344856093
So let's say you have a portal on the moon and one on earth.
Would the air also stand still?
You're dumb, mate
>>344856113
>HAHA GMOD PHYSICS ARE REAL LIFE PHYSICS OR PORTAL PHYSICS
>>344856113
the box bounces off the fucking wall before it even registers that a portal is present
>>344856137
The same thing that happens if you put two magnets with the same polarity together.
Their fields make it physically impossible for them to directly touch, or intersect.
>>344856189
>not lego
>>344856160
Air would get sucked out as if you had opened a hatch on a space station.
Putting a portal on a wall on earth, and a portal on the moon is physically the same as that wall being between you and empty space.
>>344856183
They can't be real-life physics since portals don't exist, and yes it is the Portal 1/2 physics since it's literally the same fucking game
>>344856234
But with enough pressure they do touch.
>>344856242
Excellent idea!
>>344855884
this is a silly premise simply because of the passive speed of the earth moving through space, if you were to extend the scope of the problem beyond a test chamber in a game.
>>344856289
>pressure
dont use words
>>344856264
Pretty sure that these G-Mod portals weren't added by Valve, but were made by fans. The portals were made specifically for Portal and are not something that just comes with the Source engine.
>>344856183
But that's basically exactly what would happen. All movement is relative (Einstein) so you would be thrown through with the velocity between you and the portal.
>>344856189
Replace the rocks with Lego and we've got a deal.
>>344856264
Gmod isnt portal it's Gmod it's a different source engine and it doesn't matter if portals don't exist in real life they've already stated in the game Speedy things go in Speedy things come out not speedy thing comes toward you and you come speedy out.
IT'S A DOORWAY
>>344856183
The original Portal engine "solves" the problem by simply refusing to let an object pass trough a moving portal, acting like the object was hit by a solid wall.
>>344856189
>>344856242
>>344856374
>Not covering the rocks with a backyard inflatable water slide
Why is /v/ this fucking stupid?
>it's not a doorway
>>344856364
Einsteins stolen theory has been proven wrong how many times now?
>>344856390
>Speedy things go in Speedy things come out
This was just a way to simplify things, stop quoting it as if it's the holy grail of these discussions
>>344856501
What is it?
>>344856501
/v/ never passed highschool physics
>>344855135
He would die the moment his feet hit his head
If portals aren't real then what about wormholes?
>>344856483
But earth is moving.
>>344856357
>>344856264
There was a video from someone forcing a portal on a moving platform in Portal too. The game just uses the player's velocity under the assumption that you would not have a moving portal. The answer in Portal physics is that the moving platform would just hit the block like the portal isn't there because the block has no velocity and can't go through a portal.
this ones a real killer
>>344855921
fuck, i haven't inclined the portals into the design
>>344856505
Never, actually
>>344854369
The worst that would happen is you would fall off the slanted platform when you appeared out of the orange portal.
The blue portal does nothing to literally yank you up off the platform you're stood on. It simply decides which parts of you are appearing out of the orange platform.
How has there been an entire thread of this shoy, even for bait it was obvious what would happen.
>>344856635
Place the blue one at an angle
>>344856608
portal physics are limited by the computer being retarded then
how awful
The cube has no momentum, it would simply fall.
>IT'S LIKE ALL RELATIVE BRO
Shut the fuck up.
>>344856606
Not for the game.
The black void with the map loaded is endless and static.
>>344856345
i think I can improve on this design
>>344856637
Sure kid have fun with your scientism polytheistic religion of pseudo science idols.
>>344856743
This would be great for amputeess
>>344855546
That's a wrong way of thinking about it. Imagine it being a room with a door moving at you very fast while you're jumping. It's called frame of reference, bud.
DUDE DIDN'T YOU GUYS PASS HIGH SCHOOL PHYSICS?? IS ALL RELATIVE BRO
>>344855701
Only the place on the other side is moving with the doorway, so you're going to fly into that place either way.
>>344856626
Add a grill after the blue one
>>344856757
How?
You still only have one arm. It's just on the other side of your body now.
>>344856513
Because Speedy portal goes through you and you come Speedy out makes so much sense right.
>>344856803
The exit portal doesn't create a separate instance of the world, retard. There's only one frame of reference.
>>344856803
There's only one way to think about it.
Portals arent real, they're a made up concept, and the creators of this concept state that objects only retain momentum they already had when traveling through portals
Trying to explain a completely fictional premise with real science is retarded.
>>344856751
I don't see you disproving it dipshit
>>344856879
>still using the same quote to explain.
nigga pls.
>>344855834
Everything in the universe has it's inertial perspective. There is no single set point against which everything is measured.
>>344856829
Nah, that one is too sensical, it actually adds some extra, possibly lethal height
>>344856886
What do you see when you look through the portal coming at you?
You see a world moving towards you.
>>344856751
>Made-up Hippie forest-kin buzzwords.
>>344856837
I passed it, but we didn't really learn much.
>>344856891
They were only talking about the movement of the object passing through, never the portal. The developers themselves have never actually answered what would happen if you went through a moving portal, not in the game or in any explanation. It's up to assumption and science.
>>344856886
When the portals are not moving relative to each other, there is only one frame of reference. It's impossible for something to move and not have it's separate frame of reference. That's the definition of moving. If you look through that portal, you will see a room moving at you really fast. You won't just magically stop at it's entrance.
>>344857043
Monster
>>344856971
Yeah, the world moves to you and then stops when you pass through the portal. *You* aren't moving. As the game would say at the start of 1, you have no momentum to maintain as you pass through.
>>344856971
So now you're saying the exact opposite of what you've claimed would happen, you would be pushed back by an entire universe worth of air rushing towards you.
>>344856856
But then he can't fall through in the first place. In other words, this is a flawed design for a torture trap.
>>344856364
>All movement is relative (Einstein)
Einstein postulated special and general relativity. This is not relativity of motion (rather a much more advanced version of it that handles situations people wouldn't notice on earth), which has been known since at least Newton, and surely much earlier since it's basically common sense and not some empiric finding
>lol portals are doorways there's no speed bro :)
>earth rotates 1180 km/h
>>344857034
All you've done here is solved why arcs exist and you didn't even conclude that
>>344857020
Did you even play the games?
The explicitly state in the first portal that objects traveling through portals retain their momentum.
They never say anything about moving portals.
>>344857135
No acceleration = no speed.
Which is it?
>>344857201
thats not how it works reee
>>344857201
>No acceleration = no speed.
no
>>344857201
wrong :^)
>>344857164
>they never say anything about moving portals
That's exactly what I just said. The game avoids it by denying moving portals because even the devs don't want to deal with the question of what would happen because it's more complicated than just "it's a door".
>>344857135
Yes but this inertial force is present for both the blue and orange portals if both of them are on Earth (and probably at roughly the same latitude too).
You can assume that the net force is therefore practically zero.
>>344856743
>invertedcontrolls.png
>>344857214
>All that work wasted on Portal puzzles, which are always unsolvable
What about a continuing infinite torture? For example he is pushed off a cliff into a portal that teleports him back onto the cliff to be pushed off again, back into the portal and so on forth. The cycle continues.
>>344857201
wow, so if I drive my car at a constant speed of 80 mph without accelerating or decelerating, I'm not actually moving anywhere?
>>344856929
>He used a different quote
>>344857201
Inertia is a property of matter
>>344856949
But yours makes the guy move slowly through the yellow portal, making his initial speed less.
Chances are he would only break his legs upon falling.
>>344857214
You would be flung out of the blue portal at 100 m/s because of the difference between *the platform you're stood on* and the velocity of the second portal.
In OP's example the platform the guy is stood on isn't moving. These two examples aren't the same thing at all mate.
>>344855835
Yes it is you fucking idiot, what else would they be?
>>344857135
>implying the earth rotates
>>344857346
According to you driving a car at 80mph is actually the rest of the world moving at 80mph backwards which moves you forward 80mph because all perspectives are relative.
>>344857262
They don't have to answer the question, because it's a fiction that they created.
If they don't want portals to work like that, then they won't work like that.
>>344857407
Sorry, A.
I didn't notice that the top asteroid had velocity, I only skim-read it.
this is a deadly one for sure
>>344857382
That's the entire point.
It isnt a torture device if it straight up kills people, that would be a murder machine.
>>344857465
yes that is correct
welcome to relativity 101
>>344857465
>because all perspectives are relative
Exactly. The "no speed doorway xD" theory doesn't apply here.
>>344855850
>Portal
>Not just a tube going from one point in space time to another
Kys pls desu senpai
>>344857472
Well then if they don't answer the question then how do you know what they want portals to work like in that situation? I'm saying it's an open question because it's not addressed by the creators.
>>344855357
wouldn't he just fall
>>344857465
Assuming you are in the cars frame. If you are in the roads frame the car will still have 0 acceleration but will be moving at 80 mph
>>344855135

Flung out at 100m/s. It'd act as if asteroid 2 were to simply stop moving.
>>344857310
They're unsolvable because video game engines rely on absolute values whereas reality follows the laws of physics. Relativity suggests that the answer would be A if portals existed in the real world, but most video game engines don't take relativity into account. If you did it in-game, the answer would be B. However, the man wouldn't take damage from the sudden stop, because fall damage isn't calculated realistically either.
>>344857536
>No Officer I didn't hit that lady on the sidewalk, she actually hit me relatively (Einstein)
I'll take my Nobel prize now, thank you.
>>344856483
If you look at the video you can see sparks from where the box stood, it gained momentum because it first registered the portal as a wall.
>>344857769
it's over, everybody go home

>>344855357

>>344857684
Did you not finish Portal 2? All air and pressure are continuously sucked out into space until the portal is closed.
>>344857214
Doesn't the answer entirely depend on the mechanics of the portal itself?
>>344857684
Yes actually, since the moon doesn't have enough gravity to hold the necessary amount of oxygen in order to even out the density of air on each side of the portals, the whole atmosphere will just continue to spill out onto the moon until it's all floating through space.
>>344855135
kek
>>344857856
portals are just doorways placed in 2 positions
>>344857684
No, it would lose an amount until the atmosphere on the moon had enough pressure to counteract the pressure of earths atmosphere
Everyone would still die though
>>344857684
Sure.
Portal 2 shows the suction the portals have. Since the moon cannot hold its atmosphere itwill continually go into space and new one sucked from earth. It#s basically a valve for earth's atmosphere to escape its gravity.
if you wouldn't suck your own dick after gaining access to a portal gun you are fucking gay
>>344857407
Why would the laws of nature suddenly change if the entire test chamber was moving? By your logic, he'd fly out of the portal at a different speed in the morning than in the evening, because of the Earth's orbit.
>>344857950
>not fucking your own ass hole
gay desu
>>344857950
If you can't suck your own dick without portals, you are fucking fat and should exercise
>>>/fit/17018018
>>344855220
The fucking portal mechanics in the game treat them as doorways.
Throw a ball through a hole. What happens? It flies out the other side
If the ball is floating in mid air and the wall with a hole is moved into it, what happens? Ball stays where it was.
Transfer of momentum is all shifted from the moving platform to the stationary one below. NONE of the momentum will ever reach the guy. Only thing that will happen is gravity will enact on him at a different angle once he's through, causing him to possibly fall off.
>>344854767
Impressive. Very nice.

He has to move to come out the exit and moving things have momentum. He either goes flying or gets crushed because of the discontinuity.
>>344857853
In portal 2 the portal was closed quickly, i'm talking leaving it open
>>344858093
>NONE of the momentum will ever reach the guy
you don't actually know what momentum is do you
>>344856113

Gradually.
>>344856113
delet this
>>344858309
Glados closed it.
>>344858093
The portals are moving at different speeds. Both sides of the hole are moving at the same speed. So the ball/man would need to change its momentum very suddenly to leave the portal with the same "absolute speed" with which it entered.
>>344857769
You sick fuck.
>>344857913
Which isn't something that naturally happens in physics, therefore expecting conventional physics to explain it is silly.
This is the same as that 50% or 2/3 chance on a gold ball thing where it's obviously 50%. Some people are just unable to think logically. He goes in with no speed so comes out with no speed. He just drops out and won't hit the spikes.
>>344857845
In reality, this would kill you. The closer the two plates can get to each other, the closer that the volume between them approaches zero. You'd be crushed into smaller volume.
>>344858646
>where its obviously 50

Portals cannot exist in real life because when moving- which in relation to sth. the always do- they combine two contrary movements, if you have two different moving portals the universe in relation to the one moves different than it does to the other- a universe in which both of them are at the same time!

***FAST-RESPONSE BAIT PREVENTION UNIT***
the starting case is that you have already claimed a gold ball, thus exempting the third box (2 silvers) from the problem entirely.
this leaves you with 2 boxes to have taken a gold ball from.
in each of these cases, one has a 100% chance of taking a 2nd gold ball, the other has a 0% chance of taking a 2nd gold ball.
this results in a 50% chance to take a 2nd gold ball.
simply put, there are 2 relevant outcomes in the problem, making it a simple 0/1 binary choice, or a coin toss, thus 50% chance of success.
now what i REALLY want to know is how you'd attach a portal to the inside of your pants. would you need to glue a large moonpaint plate to both cheeks and hope it sticks? if it falls off midway, will your dick break, or your ass?

>I'm sure the guy that made this thing just wants to see the world burn. Make people argue to keep them busy.
It was made by Russel Bertrand, a famous mathematician over 100 years ago and is used in academia to explain the fundamentals of probability. He proved the answer is 2/3. There's an equation and everything.
>>344859604
I think the question is just stated wrong then. It's not about being more likely from which box it comes, it's about the chance of a gold ball which is either 100% for A and 0% for B. I get that tbe initial chance is higher for box A, but that case is not relevant now. The question pertains to a ball already being chosen. Right now you either get gold or you don't.
>>344859604
>>344859309
It's 100% that the next ball you pick will be a gold ball. Put the ball you took out inside and take it out again.
>>344859653
If you pick one gold ball, you can already exclude the 3rd box.
leaving you with 2 boxes, so that's indeed 50%
The ones saying 66% are:

>>344858696
The most cruel thing is you wouldn't get crushed by a wall or something, but by your own body piling up in the portals.
Beat up by your own meat.
>>344859653
They're not equal though. It was twice as likely that you had picked the left box than the center box, because it has two gold balls.
>>344859005
No dude the portal is ON your ass
>>344859813
>but that case is not relevant now
yes it is, because you are more likely to have picked the first ball from A then you are more likely to find a 2nd gold ball in there
>>344859360
These portals only work because they are scripted.
And they completely coincidentally only move sideways and laterally to each other so a velocity problem does not occur when noclipping and flying through them, you simply come out at the same speed off the other one.
All those problem occor when portals move forwards or backwards!
>>344859309
2/3, because I didn't fail my high school math classes
>>344859851
Sorry I'm a tad confused.
What if I pick a gold ball from the box with two gold ball in it ? Would that change the outcome and probability ? Because I can't exclude any other box then because I'm unsure whether I chose a ball from the box with two gold balls or one gold ball ?
>>344857845
trippy
>>344859863
so did the guy marry his fucking mom or something
>>344859653
You have already picked a gold ball, so there's a 0% chance that you have Box 3 (all silver). There are three possibilities:
1. You're holding the first ball from Box 1. The next ball will be gold.
2. You're holding the second ball from Box 1. The next ball will be gold.
3. You're holding the first ball from Box 2. The next ball will be silver.
Of these 3 possibilities, 2 of them produce a gold ball. Therefore, the odds are 2/3 in favour of picking a gold ball again.

>>344860083
I would "Solve" that "Puzzle" if you know what i mean:^)
>>344859745
This basically.
It took me a while but then I realised it's kind of a trick question. A lot of people are looking at the problem as if all three boxes matter, but it doesn't. You have to pick the same box TWICE and get a gold ball at least once. This automatically excludes the all silver box, since you can't get a gold ball in the first place if it's all silver.
>>344859745
There are 3 relevant outcomes
>>344860110
That made sense , thank you anon.
>>344860281
>this
but youre wrong, its 2/3, and that number is still ignoring the silver box
>>344860281
>A lot of people are looking at the problem as if all three boxes matter
No, they're not. It actually doesn't matter if you include it in fact, the equation is perfectly suited to deal with all three boxes and come up with the same solution whether the all silver box does or does not exist.
>>344860071
No, you can exclude the box with 2 silver balls in it.
Leaving you with either the option that your next ball is gold or the next ball is silver; 50% chance

what the fuck would happen in such scenario?
i dont get how it'd crush him
>>344860327
No it doesn't. It's 2/3 but for different reasons. You already chose a box, so the one with two gold balls is one case and not two.

>>344860446
>either you win the lottery, or you don't
That's not how it works. There are two gold balls in the left box, so there are two scenarios in which you chose a ball from the box. In all, there are three scenarios. Two of them result in two golds.
>>344860446
correct, but the gold is more likely
>>344860419
just because there are two outcomes doesnt mean the probability is equal
>>344859309
You ignore the silver box. You have to, since the puzzle asks you to draw a golden ball from a box and then draw from the same box again. Obviously, if there's only silvers in one box then there's no way to get a gold ball from it.
So if you ignore the all silver box, there's only four balls right? And three of them are golden, so the chance of you initially getting a gold ball is 3/4. You know, since three of the four balls is golden and there's only one silver.
Now you're left with three balls. Two are gold, one is silver. So in other words, it's 2/3.Why couldn't anyone else explain it this simply?
>>344860630
It's not about the which gold ball you pick.
It's about which box you pick.
So it doesn't matter if you grab your own ball or that of your mom first

it depends on how you look at it
you may be crushed in on yourself as you are the only space between portals
you may be crushed between the platforms
you may be trapped in an infinite void that is the 'space' that a portal uses to transport one side to another, which is of course impossible to confirm the existence of because it is a mere gameplay element, particularly when you don't know the source code

RETARDS
You'd fly out the portal at 100km/h, or however fast the blue portal slamming down on you is. If the portal moves down at X speed, you'd have to exit the orange one at X speed. You "lol no momentum" fags for some reason assume all that momentum would suddenly stop as soon as you fully exit the orange side.
Imagine a coin was suspended just outside the portal. It's going to be hit by an object moving at 100km/h, it's not going to just flop to the ground, it's going to be propelled across the room.
>>344860774
except that the ball does matter, because with the Gold/Silver box there is a chance of picking the silver first, thus taking it out of the equation
every time you pick the gold gold box you will have a gold ball first, so its going to be the box you picked the first ball from twice as often as the gold silver box
>>344860774
It doesn't make a difference. If you pick the center box, there was only a 50% chance it yielded a gold. If you pick the left box, there was a 100% chance it yielded a gold. The average of this is (1+1/2)/2 or 2/3.
>>344860943
Correct.
But you can already neglect the 3rd box since it doesn't contain gold balls. You're only left with either the left box or the middle box that was picked.
That gives you 50%
>>344860992
Actually I got that wrong, it's not the average, ignore that part
>>344859745
Are you fucking retarded?

>>344861094
No you're not you fucking faggatron, you could have taken either of the balls out of the left box and be left with a new result. It's 2/3.
>>344860774
it isn't though!
the question asks first that you pick a box, yes, but it goes on to continue that the starting case is that you now hold 1 Gold ball, which only happens after picking a box.
boxes are unimportant here other than as a boundary to limit pairs of balls.
the question from then on refers to your taking of a second ball. given that there are 2 balls per box, you do indeed have the option of taking 2 Gold balls from the first box to produce separate outcomes (regardless of whether they are equivalent, they require branching paths of action to reach, so you must presume them as separate outcomes).
and then on we go etc etc 2/3
>>344855546
>there are homeless people that hop trains smarter than some people on /v/
>>344861094
No no you start off with four balls. You draw one ball. There are now three balls. Of those three balls, you have a 2/3 chance of getting a gold ball as 2/3 of them are gold. If you were to draw a THIRD time then you'd get 1/2 chance of getting another gold ball sure, but you're only drawing twice.

Here's a valid counterargument if you really want one.
You're already holding a gold ball, the 2 boxes that are left each contain 1 ball
What is the chance of getting another gold ball?
>your answer: 2/3rd
>>344859542
>the tests are wrong
Do it yourself, it works. I've done it, academics have done it for over 100 years. The answer is that every time you pick a gold ball, the chance that the next ball is also gold is 2/3, and this has held true constantly.
>>344856113
Inaccurate, since Portals do not work properly in GMod. GMod can't detect them fast enough. In this case, the block has absolutely no reason to the spinning, UNLESS the platform acted as an outside force.
The block only has momentum because the game registers the platform hitting the block, THEN it registers the portals, since it is just a mod in a game that isn't supposed to have portals functionality.
>>344861481
>the 2 boxes that are left each contain 1 ball
What?
>>344861481
Wait, why would each box have one ball? If there are two boxes with two balls, and you have already drawn one ball... then you have two boxes with one ball in a certain box and two balls in the other box.
Where did the second ball go? You're only taking a total of two balls, so why are you going off the assumption you're taking three? You'd only have one ball left under your idea, which is just plain wrong.
>>344856183
Gmod uses source engine, the same one used by portal.
>>344861481
The answer is 2/3 because you're drawing the next ball from the same box as the first one, and there's a higher chance the first one came from the first box than the second box.

>>344860770
the chance is 1/2 because the left box can only give you gold so its 1/2 the only question is: LEFT BOX OR RIGHT BOX thats a 50% tho... thats it
There are two boxes.
Only one of them will let you draw two gold balls
You have a 50% chance of picking that box.
Therefore, you have a 50% chance to get two gold balls.

>>344861849
Not so fast anon, you're missing a step
You have to factor in the probability of having selected a gold ball out of either box. In the right box, you only had a 50% chance. In the left, you had a 100% chance. No, the problem is not saying you had a 100% chance in both just because it tells you the outcome, that's not how probability problems work.
>>344861849
except in this problem you've already picked a golden ball

Wrongly worded.
Was meant as in both situations that are possible.
>>344861953
You can literally test this at home and notice that the chance is 2/3.
>>344859309
I feel like this problem has multiple right answers depending on how you interpret it.
If you calculate it based on balls you get 2/3. If you calculate it based on boxes you get 1/2. That being said, you have to consider why the question is written this way. If it wanted you to calculate it via balls, why not just have all the balls inside a bucket and calculate the odds of drawing a golden one? That would remove all ambiguity after all, and it's the standard question for this sort of thing.
Therefore, we have to assume that the question is posed in this specific way because it wants to be answered in a specific way. It's written as boxes because you're supposed to use the box method for calculating the answer.
While the ball method is theoretically correct, in practice all that really matters is what box you chose so it absolutely must be box based.
>>344861953
Is it pseudo-intellectual if it's tested, proven, and taught in academia?
>>344861182
No you listen here fagzilla, you just took one ball out of one of two boxes.

>>344861267
hello it is me
basically boxes are just a metaphysical construct designed to help you imagine the balls as separate pairs so that you have some unique path to take for 3 situations, they are not an integral part of the problem in themselves.
the problem simply asks you to imagine that you have blindly chosen 1 Gold ball of 2 balls in 1 of the 3 separate situations, and then to imagine, from this starting point of you having picked 1 Gold ball, what the odds would then be of you picking a 2nd Gold ball.
of course, starting with 1 Gold ball means that you have already not chosen a ball in the 3rd situation, as there are 0 Gold balls there. we are therefore limited to having chosen 1 Gold ball from situations 1 or 2.
in situation 2 you are limited to 1 base case (and because this is a linear problem with no branching paths, only direct consequences of your first choice, you will only have 1 outcome per base case): because you MUST start the problem with 1 Gold ball, and there is only 1 Gold ball in the box, the probability of picking a Gold ball next is 0%, making the current count of [successful outcomes] to [total outcomes] 0 in 1!
in situation 1, however, there are 2 Gold balls. this means you have 2 base cases, which will in turn produce 2 outcomes. since there are 0 Silver balls in this situation, you have a 100% chance of picking a 2nd Gold ball upon picking the Left Gold ball, and a 100% chance of picking a 2nd Gold ball upon picking the Right Gold ball!
when you add these 2 outcomes to the 0 in 1 current outcome success rate of situation 2, you will reach 1 in 2, and then 2 in 3, or if you're sick of reading 2/3 in this thread, a 66.6% probability.repeating, of course.
hopefully this is more complete of a response!
>>344862064
it IS calculated based on boxes and you get a 2/3, because the gold gold box is twice as likely as the gold silver box to fit the parameters of the question
>>344862064
No, in no possible world is the answer 1/2. It doesn't matter if you say "based on boxes" or "based on balls", they're exactly the same. Welcome to probability.
>>344862008
we search for the chance after the first pick so we say we have the 1st gold ball allready
>>344861967
But you've ALREADY drawn a gold ball, so this means it's impossible to pick the all silver box. Therefore, you could of only of picked between the two relevant boxes that lets you get at least one gold ball.
>>344861935
Already picked up a gold ball first, read the question.
>>344862007
You have a 50% chance of getting 100%
>>344862064
There are no multiple interpretations. All you have to understand is that the first draw was also random but we're only considering a situation where you got a golden ball.
>>344862064
>I feel like this problem has multiple right answers depending on how you interpret it.
It has one fucking right answer. If you take three real boxes, put six real balls in them and then actually do the experiment in real life you won't get two fucking probabilities depending on how you fucking interpret it. You will get 66%.

while Portal and GMod do use the same engine, moving portals were only introduced in a scripted sequence in Portal 2, running on source2 engine. so the two are already fundamentally different at some level.
secondly, the portal implementation in Portal was created by valve employees. the GMod implementation was likely created by one man with few tools and educational resources as a hobby, and is absolutely less detailed, polished, and refined as the Portal version of the same concept.
anyway, if we are going to be examining the Portal universe, we may as well follow the coding examples of the Portal games, because that would be most equivalent to the 'fundamental laws of physics' in that universe, given that portals are a gameplay feature entirely handled by the code written by the developers.

It depends on how you look at the problem.
If you think it's 1/2, you mostlikely took the 2 boxes and removed one gold ball of each on,which leaves you with 1 gold and 1 silber ball thus a 50% chance.
But if you think it's 2/3, you used the balls.
you took 3 gold balls,2 leading to each other and 1 leading to a silver ball,thus you have a 2 in 3 chance of having the gold ball again.
This problem must have been one big joke.
>>344862272
>you already picked a gold ball

You made a mistake, and that is you're assuming that you can pick the all silver box. Since you need to have already drawn a gold ball, there's no way you could of chosen the all silver box.
The silver box is there to trick you, it's a red herring.
If you get two boxes and put 2 gold balls in one and 1gold and 1 silver in the other, half the time you're going to end up picking the one with two golds.

>You made a mistake, and that is you're assuming that you can pick the all silver box.
You can, and that is how you would do the experiment in real life. You would just reset and draw again if you got a silver ball. The draw you're doing is random.

50/50.
Since they both have at least one gold ball in them and all you need for the first draw is one gold ball, you have 100% chance to get a gold ball from the all gold box and 50% chance to get a gold ball from the mixed box.
So when you average it out, you have a 50% chance of getting a gold ball. The fact that the all gold box has two gold balls doesn't matter for the first draw, since you only need to get one gold ball.

the question simply becomes do you have the first box or the second box, which is a 50/50 question
>>344859309
We take a gold ball out first. Therefore we can completely ignore the third box.
The problem asks what is the probability of taking another gold ball from the SAME box. So, from the two remaining boxes, take one gold out and look at the chances, it's 50%.
If you initially picked from the two gold ball box, you will 100% get another gold. If you initially picked from the middle box, you have a 0% chance of getting a gold. the average of these is 50%.
Anyone saying 2/3rds forgot you're picking from the same box you originally picked from.
>>344862743
It's a thing of wonder, isn't it?
>>344862583
Read the question. You need to of picked a gold ball to begin with. Sure, in real life if you did it you might accidentally pick the all silver box. But that doesn't count, since the question starts off you you already having drawn a gold ball.
>>344862771
No.
>>344862506
It literally makes no difference to the problem whether you include the silver box, the answer remains 2/3. Wanna see that mathematically?
The equation for the problem is 1/(1+1/2+0) = 2/3
The 0 represents the silver box, since it has no probability of having been the solution. Notice how you can remove it and the solution doesn't change.

And drawing the first golden ball is more likely if you picked the first box than if you picked the second box. This is what causes the overall probability of getting two golden balls to be 2/3.
The thing that amuses me most about this thread is all the 50% retards condescendingly shaking their fingers and going "You got tricked by the third box, you silly fool, let me enlighten you :^)"

>you either picked the first box or the second box
except that HALF the time you pick the second box you would have drawn a silver ball first
you draw a gold ball first 2x as often from the first box, so the probability of the box you chose being the gold box assuming you did draw a gold first is 2:1

>>344861849
Ball A = Gold (0% of getting Silver next)
Ball B = Gold (0% of getting Silver next)
Ball C = Gold (100% of getting Silver next)
Ball D = Silver
This means that there are 3 Gold balls, and two have absolutely 0 chance of getting a Silver. That means that every 2/3 balls will get you a gold ball next.
>>344863068
but it could, the 2nd box fails to meet the conditions half the time, the 3rd box fails to meet the conditions 100% of the time and the 1st box always meets the conditions
thus the 1st box has the higher probability of you having picked it
>>344863076
There's only one correct interpretation of the problem and the answer is 2/3.

You are on a gameshow with three doors. Behind two of them is a box with two balls each. After picking one, the host asks if you wish to stay or switch. What are your chances of getting a second golden ball?
Okay everyone stfu, I'm the anon who posted the first mention here of the box problem and I was wrong. It's 2/3 and I was a fucking retard for saying 50%.
>>344859309
This puzzle is fun. The solution is so insanely simple to grasp but people still argue about it.
>>344863241
It really doesn't matter, because the question states you already got a gold ball. Why would you go off into a hypothetical situation that's different from what the question is asking?
If I ask you what year WWII started, you wouldn't say 1925 based off some weird hypothetical situation in your head would you?

Does that change the possibility?
>>344863193
in that description you can interpret it either as ball or box
>>344859309
either 1/2 or 2/3
1/2 if you discard the box that you took the golden ball from, 2/3 if you do not.

>>344864026
>>344864047
is that ting going to be a meme or sth
>>344863481
but you cannot!
the base case is where the question tells you that you have just taken a 1 Gold ball, not that you have picked a box.
again, the idea of a box is simply to provide you with a pair of balls and to provide some boundary between them to better facilitate your understanding of the problem.
there is no interpretation of you being the one to pick a box, since the problem starts where the most definitive statement in the question lies -- that you have taken a gold ball.
this does not mean that there is now a 0% (or 0 in 2) chance affecting your solution to the problem being enforced by the 3rd pair of 2 Silver balls, it means that they are discounted entirely from your solution, as there is no conceivable way that you could have picked one of them in order to be currently holding 1 Gold ball.
because of this, the only balls available to be picked in this problem are 2 Gold balls and 1 Silver ball.
this leaves you with the figure of 2 in 3 balls being Gold.

No but it's not a ingenious new way to torture someone using Portals, it's just an obvious way to make someone suffer.
Also couldn't you logically just reach out and grab the edge of the portal before you fall through?
>>344862494
I do, but I also know how significant the difference in mass is, and that it doesn't take much for something to reach escape velocity on the moon, that the Earth has an effective gravitational pull beyond the moon, and this is fast moving gas we are talking about.

>grabbing a ledge at near terminal velocity
You can't really do anything amazing with portals unless you have also the boots, otherwise the first time you flinged yourself would also already be the last time.
>>344864323
The only animals mentioned are dog, bird, cat and horse so we don't know if the last animal is a fish at all.
People who think the portal will launch you are the same people who think that a plane wouldn't take off on a treadmill, aren't they?
>>344864772
The boots are almost the more impressive invention of the two- I find it amazing how Chell can avoid sustaining any falling injuries with them, even when she lands on her skull or face. That's some serious talent in engineering.
>>344864906
How is the plane gonna get lift if the wings aren't moving relative to the surrounding air?
>>344864483
You realize you are pumping the gas which partcles are several 100 km/h fast and that has no other desire than to dilute itself into a near perfect vaccum, right?
It would spread so fast that the initial velocity from getting sucked is nearly irrelevant.
>>344859309
The answer isMathematicians are faggots who think too much about balls
>>344864995
Someone needs to pack the atmosphere into balloons before it gets sucked out so it'll stay together and drift back to earth.
>>344864989
Like clockwork. Stupid people or trolls.
>>344864906
>this guy
It's the air moving over the wings that create lift.
It's not the speed itself that does that
>>344855741
now you're thinking with portals
>>344855546
you are retarded
take a look at this picture
>>344865215
And as soon as the blue portal hits the end of that platform it will stop moving.
>>344860963
The portal doesn't have any momentum itself, it's merely a gateway to the other portal.
>>344854868
>>344855335
Are you pretending to be retarded?
>>344865323
im trying to demonstrate that the box on top of the railing will fly away , and the moving portal is the cause of that that happen.
>>344865459
Read the rest of the thread, it's pretty good proof that a good portion of /v/'s userbase were dropped on their head repeatedly as babies.
>>344865134
Then explain. If the plain stays in one place on the treadmill there is no airflow around the wings.
Let's say you have to multi-taps (those things you plug in the wall that have additional power sockets, so you can run multiple devices off a single wall socket, you know what I mean)
So you plug multi-tap A into the power socket in the wall. Multi-tap A now has power inside it.
Then you plug multi-tap B into multi-tap A. Now multi-tap B also has power running through it.
Remove power tap A from the wall and plug it into multi tap B.
Do you still have power?
This isn't one of those troll logic infinite energy things, since obviously the multi-taps only have a finite amount of energy inside them (if they have any at all)
>>344865323
Where does the momentum go?
>>344865496
The box on the railing is staying right where it was, on the railing. The railing is moving, but it will stop as soon as the blue portal passes over it.
>>344865528
The plane will send get forward momentum because it's not wheel driven but jetdriven.
>>344865554
Where does the momentum go when you crash into a wall?
>>344865546
What is electrical power? It's essentially a potential difference, leading to an electrical field.
As soon as you remove A from the wall, the field collapses. The electrons are still in there, but they won't move anymore.
What would happen if you shot one portal on the surface of a fast spinning neutron star? Would the magnetic and space-time curvature (gravity) fields go through the portal? Can someone draw me an accurate form of the space time curvature change around the portals? I'm literally too retarded to even begin understanding myself
>>344863803
Blue and black. the argument is due to lighting.
>>344865554
Nowhere, there is no momentum. It appears to be moving from the perspective of the orange portal but it hasn't gone anywhere, it's being shuffled through an open door.
If someone drops a sideways room on your head, doorframe first, from the perspective of the people inside the room you'll fly in through the door at extremely high speeds. But after the door hits the ground, you'll just stop. You won't fly violently into the opposite wall, because regardless of the perspective of the people inside the room, you have no actual momentum.
>>344865546
There's not "power inside" a multi-tap plugged into a wall. The circuit is still open unless you plug a device into it.
>>344858696
>in reality
>>344854767
Kek'd hard/10
>>344865373
Not the guy you're replying to, but...
Your body would have to come out of the orange portal at the same speed as the blue portal is coming down.
If your body is disappearing into the blue portal at X speed, it must also be coming out of the orange portal at X speed too.
The force of your own body coming out of the portal behind you would push you out of the orange portal with all of the momentum that the blue portal came down with.
>6/10 bait. Got me to reply.

>>344865528
The only way it will fail is if the wheels can't handle spinning twice as fast.
Have you ever seen a plane before? Do you think they're literally just cars with wings? The wheels are there to reduce friction as the engines on the wings/props propel it.
For fuck's sake, do you think a sea plane has hidden outboard motors in the floats at the bottom?

Portals don't 'force' you through, they're just empty holes in space. There's no pressure and nothing being forced against something else because there's nothing there, thus the doorframe comparisons in this thread.
>this thread
they didn't call /v/ the dumbest board for no reason
>>344858123
I like it
>>344866284
The portal isn't forcing you, but if you're halfway through that blue portal, and it's coming down on you at 100km/h, then the rest of your body is coming through the orange portal behind you at the same speed.
That momentum can't just stop after your body is finished coming through the portal.
That speed is what's forcing you to shoot out.
>>344856137
how can a wall small enough to fit in a portal also be big enough to hold a portal?
>>344866497
>That momentum can't just stop after your body is finished coming through the portal.
Sure it can, because there is no momentum, it's an illusion. See >>344865792 . If someone slams a room down on your head at speed, you don't match that speed and then go flying off because of it. Portals do the same thing, but in the same space, so instead of slamming another room down on your head, it slams the same room down on your head. You're still not moving either way.
Speed of entering blue portal = speed of exiting orange portal. That momentum doesn't just disappear after you've gone all the way through.
thats kinda the best thread since months i have read on /v/
>>344865684
Transformed into energy (wait, it already is energy isn't it?) that fucks over the front part of the car.
>>344865792
>>344866634
Or in other words, it's not you that has momentum, it's the world that has momentum. You're standing still. The world's momentum doesn't transfer to you unless you're anchored to it, which you are not.
>>344861660
>It's just like a hoop!
Wrong.
In the real world the 2 ends of the hoop are connected, as one side moves down so does the other. If you put 2 portals on either side of a flat surface, like a piece of paper, it WOULD work like your dumb hoop explanation as the momentum of the box traveling through one side is canceled out by the exit portal moving down at an equal and opposite speed.
However in the given scenario the portals don't work like that, the exit side is stationary whilst the entrance is moving. Therefore the velocity of the object being forced through the portal isn't canceled out by anything therefore it has to exit the exit side at the same speed that the entrance slams down on you.
>>344866826
But the exit is moving from the perspective of someone being put through the entrance, thus making the hoop analogy complete. It can be both moving and stationary because it's space time fuckery, it doesn't have to follow the laws of physics.
>>344866808
But if the world has momentum and you are stationary, for all intents and purposes wouldn't that mean that you have momentum?
If I jump and the world moves a meter backward, practically speaking I jumped a meter forward.
>>344867016
No, because we're talking about two 'worlds'. You're exiting one and entering another. The momentum of the second 'world' has no bearing until you're anchored to it, by, say, stepping into the room that's crashed down on your head.
The trick with portals is that one world is split into two until you anchor yourself through it.
>from the perspective of the person, the orange portal is both moving and not moving
Explain this
>>344867384
Because portals are doors into the same space, it 'duplicates' the space. There's four effective portals any time you have two open, two on your 'side', two on the other 'side'. The entrance on your side and the exit on the 'other side' are linked and moving together, even as they're separate and stationary on 'your side'.
This is the whole conceit of portal in the first place.

Found your problem. You're fixating on the box, not the balls. The box is just a framing device. It's 66%, as proven multiple times in the thread and in real life. Go ahead and duplicate the experiment IRL and you'll get 66%, not 50%.

>>344867006
>the exit is moving from the perspective of someone being put through the entrance
What? That's irrelevant.
And there's not 4 portals, it just makes the distance between two points 0.
How can it be anything but 50%? It makes no sense.
You already picked a gold ball, so either you get a silver ball or you get another gold ball. It''s 50/50.
>>344868236
You could have picked either gold ball A or gold ball B from box 1. Because you're double dipping, it increases the odds that you'd get a gold ball from box 1 where the other ball is guarenteed to be gold, which influences the probability.
>>344868236
if you relate it to the chance by picking one box yes...
we want to pick one of 3 balls of the 3 balls are 2 gold -> 2/3
