When I bring my pocket am radio close to my tablet why does it pick up the audio emanating from the tablet and amplify it and drown out the am station I am listening to? Spoopy.

Guys, I have math related question

Let's assume that Asians comprise 5.6% of US population
If an airplane inbound for Kentucky chooses to randomly boot 4 passengers, what is the chance that three of those passengers are Asians?

There goes your experimental setup. US demographics are not representative of those of airline passengers.
>>
>>8820265
that statistic is so high because of California.
most parts of America you would be lucky to see an asian person. if you did it would probably be a mail order wife of a white guy.

Einstein was a German Ashkenazi, who grew into adulthood whilst in Germany, making him German.

Tesla was a Serbian, who also grew into adulthood whilst in Serbia.

This makes them both socially, non-American and infact, German and Serbian respectively.

Hey /sci/,

I come to you in search for advice and maybe other experiences.
I have a medical condition called Paruresis. I just can't pee when other people are around me. no matter if they can see or hear me.

Don't get me wrong I don't have a problem with getting my dick out and everything.
Not only once I tried to pee with a really filled bladder at a festival to the point where it hurt.
But I just stood there for like 15 minutes trying to pee. I only could pee when I went to a stall (is this the right word?). It also doesn't work when I'm with friends.
It was not from birth on but from somewhere in secondary school on. There was no traumatic experience I think.

This is really becoming a torture. I can't drink anything when I'm going out with other people because there is always one of the group coming along when I go to the toilets.
When I am in university I always sneak off and go to an unoccupied toilet. (Luckily there always is one in my university).
When I was in the military I also somehow managed to only pee when I was alone.

Please some med students, I need help. How can I overcome this? I really try and I take my time people come and go and I'm just standing there for 15 or more minutes....

>Pee-shy faggot
Just go in the stall and sit down
If you stand up and pee in the stall, and piss all over the toilet seat, you are an asshole

I used to work with a pee shy dude and he told me there are also support groups for this
He and his pee-buddy would get together and practice
>find busy bathroom at lunchtime
>help each other pee
I still think they were gay together too

Anyone know about geometry of learning?

The machine learning boom is a desperate attempt to generate value from "Big Data" which everyone is extremely invested in, we're in for a huge bubble burst when naive optimism starts declining.

that money wasn't going towards launch vehicle technology. it was going towards climate change research and other white mans welfare boondoggles completely unrelated to space travel.

NASA has become a "catch-all" agency and has severely strayed from its original mission statement.

(((estimated from average GRE scores)))

if lambda equals 1/50 (flaws per yards) and 50 yards inspected, what is the probability that the number of yards that have one or more flaws is fewer than or equal to 2?

My problem here is not how to do it, but whether I include 0 or not. I'm using a poisson distribution

Lolz poisson means fish in French so nerdy xD
>>
>>8819791
such insightful help
>>
>>8819778
I think you need to include the yards that have 0 flaws in your analysis. Pr(X=0)+...+P(X=2)=P(X<=2) if I am not retarded.

If this is not enough maybe I misunderstood something.

1 time dimension is like watching a movie start to finish composed of frames
A second time dimension is the folder containing screenshots of every single frame of the movie

I'm retarded and probably wrong, though
>>
>>8819750
You'd have to make up what a second time dimension actually means, as I don't think it's defined at all. I'll just go with it enabling parallel multiverse theory.
