"Stay or switch" is relative to your first choice. When the exact same scenario of door openings happen but the question posed is "pick a door" - ie, not relative to your first choice, the probability is 50/50.
Your second decision is not dependent on your first decision, as the outcome of the first decision is always the same (a goat door is opened). The only thing making your first decision relevant to probability calculations is the fact that 'stay or switch' requires it. When the exact same events happen but the question posed is "pick a door", your first choice is not relevant to the probability calculations which makes it 50/50

You fuckers are still doing this shit?
Fuck off OP there are countless explanations and examples for this.
No its 2/3

The monty hall problem - ie, stay or switch - is 1/3 to 2/3. This is empirically proven.
But the exact same series of events - with the only difference being the second question is "pick a door" (which is not dependent on the original decision in any way) - is a 50/50 chance because your first decision is not relevant to the probability calculations.
The outcome of the first decision is always one goat door being opened. You have no influence over this outcome. No matter what door you pick, this outcome will always be the same. Your decision was not important.
The only reason the first decision is counted in the probability calculations is that "stay or switch" is relative to the first decision.
When you eliminate any link to the first decision in the question (ie "pick a door"), there are no longer any ties to the first decision and it should be disregarded entirely from the probability calculations.
This is no longer the monty hall problem, but an identical series of events with a different question being asked

Can we get a tricky differential equations thread going? ODEs and PDEs of all orders welcome.

Post shit people can actually solve/have solved. I'll start with this:
>>8584799
I hate numbers so much
[eqn]
\left[r^2 \partial_r^2 + r \left({3\over \ln r}-2 i \cot\theta \right) \partial_r + \partial_\theta^2 + i\left({3\over \ln r}-2 i \cot\theta - 1 \right)\partial_\theta\right]\,F(r, \theta) = A\, F(r,\theta)
[/eqn]
[math] A [/math] is constant and [math] r [/math] and [math] \theta [/math] are on the unit disk.
For those of you who think you can solve it on the first go - think again.

How did early humans and neanderthals manage to produce fertile children, despite being two different species of homo?
Same number of chromosomes.
>>8584695
I get that, but a species is often defined the major subdivision of a genus or subgenus, regarded as the basic category of biological classification, composed of related individuals that resemble one another, are able to breed among themselves, but are not able to breed with members of another species.
>are not able to breed with members of another species.
Thre is no temperature in the space because vaccum. So why we say that the space is very cold ?
there is temperature
there is no heat
cold is the abssence of heat, therefor it is cold in space, cold in the bottom of the ocean aso.
>>8584601
Yes but the temperature is a property of atoms...
And there is no atoms in the space...
>>8584604
Nigger, space isn't a perfect vaccum, for a perfect vaccum you couldn't even have photons.
Solve this problem!

It's called finding your own reason.

hey lads, had a thread on here a week ago.
let's talk sports books. Which sport have you applied your /sci/ence on to making profit? Bet the winners of an NBA game? spread on NFL perhaps?
im horse-race-fag from last week. in later stages of building my ML algorithm for thoroughbred US horse races.
>>8584330
When I need more money I just go to vegas, put $10000 on red. If I win, I leave (I made a profit). If I lose, I put my net losses on red and repeat. Gauranteed win.
>>8584337

>>8584330
Might work for horse racing since a lot of the horses are of the same bloodlines, fed and trained the same, etc. Its not a good idea for other sports without consideration of a fuckload of variables including day to day stats on the individual athletes because you'll probably train your algorithm to just always bet on whoever is winning instead of what makes them winners, such as training regimen, staying clean in season, proper sleep, not facing off the field/court drama, raw athleticism, age, their sports IQ for their position, their ability to work in a team, status on their relationship with coaches and teammates, if the coach has anything going with them,...
Way too many variables that can screw things up, and if you use something as simple as box scores and season stat sheets for things like passing yards or sacks, you won't be able to pick winners. Closest you'll get is being able to know for sure when some team is about to get BTFO by another team that completely out classes them all around.
Would be interesting though if you train it to browse news outlets and twitter profiles of athletes to try and get a read on if they're mentally there week to week for a game.
Interesting paper on the correlations between college education, economic dissatisfaction, racism and sexism and the likelihood of voting for Trump.

Anyone want to give it a read and give thoughts on the statistical methods and/or the conclusions? I don't read poli sci papers normally, but I think they left out a lot of potential interaction terms in their model

>>8584322
The inherent nature of the subject makes it nearly impossible to define objectively. Given that the paper it seems incredibly reasonable. I only briefly skimmed it, but none of the language or argumentation is particularly troubling or biased in any way. And the methodology is very clearly laid out, with no signs of manipulation. And the material is presented very matter of factly without making reaching conclusions.
This is a much more interesting read because the analysis is more palpable.

What do you feel they left out they should have included?
if space turned out to be quantized, would that mean we should really be using the manhattan distances and setting pi to 4?
>>8584313
lmao
>>8584313
Lol no. If space is quantized it's not like a road network, it's like pixels. That more or less preserves pi.
>>8584313
yes that's exactly what it means.
What is consciousness?
What produces consciousness?
Will computers ever be conscious?
muh dick desu
Consciousness is being aware, what kind of awareness depends on the situation manifested around the individual, neuroplasticty can be a good answer to how consciousness is produced since you are more conscious today then you were when you were an eight year old. The answer is yes to your last question, but consciousness for computers will be artificial for the next few hundred years. But to be quite honest, computers may actually pass conscious awareness that humans have. Unique world we live in huh?

Metric as in metric spaces or Riemannian manifolds?
The former you should have no problem with, the latter is out of your reach for now.

The former I think. does discussion of L1, L2 and Minkowski space fall under that category?
