Can someone explain this? On the ISS tracker the ISS is in the night side of Earth, but on the live stream it looks like it's on the day side of Earth.

Is taking a course on Markov chains worth it for a CS babby? They seem to pop up in research papers all the time when predicting behavior of networked systems.

Any good intro to geology books?

Preferably highschool level and well explained.

Hello fellow /sci/, where I can find good reading material to start with machine learning? what is the picture of the field right now?

Eyes are a phobia of mine and I don't like to post this, but after all my years of life I realized that my lower eye lid doesn't really open fully, in fact it doesn't move at all. Whenever I make a "suprised" face, only my upper eyelid opens. Everything seems to be normal when I blink, though.

I can't be the only one to realize this. Maybe it's just me. Is there for anyone else?

I'd also like to say I realized this at 12:20 at night when I needed to get to sleep so, I don't know, do with that what you will.

Every real polynomial of two variables defined on the real plane R^2 and bounded from below attains its minimum.

Look at this smug piece of shit.
Thinking it can be a wave and a particle.
YOU HAD ONE JOB. GO FROM POINT A TO POINT B.
But no. It just wasn't good enough. you had to go through ALL THE WAYS.

I was minding my own business looking at two slits and this
Mother. Fucker. shows up and says "The fuck you lookin at, bitch?"
and turns into a particle.

So at this point I'm fed up. I create an experiment where one photon is fired at a time.
After it goes through one of each slits it separates into two entangled photons.
That way I'm not observing the photon but its' twin.
And since I detect the separate one after it hits, there's no way it can know I will be able to know which hole it went through.

So the entangled one from one hole can hit either D1, D3 and D4 after its' partner hits a screen.
The one from the other hole can hit either D2, D3 and D4 after its' partner hits a screen.
I run the experiment and when the photons that hit D1 and D2, their entangled pair formed a particle pattern on the screen.
The ones that hit D3 and D4 formed a wave pattern on the screen because ones from both slits can hit it.
This little shit knows if I WILL know in the future where it went in THE PAST.
Can you believe this nigger?
THIS FUCKER BREAKS THE LAWS OF THE UNIVERSE JUST TO SPITE ME!?

PHOTONS MAKE ME SO MAD!

Hi /sci/ I have a bit of a problem:
I have been using Latex over the past few days for the first time. Most of it seems pretty easy, but now I have a bit of a weird issue. I am using TeXstudio and texlive.
I can compile my .tex file no problem and the preview pdf also displays correctly with no errors, but when I look in the folder there is no pdf. When I press "External Viewer" in TexStudio, I also just get an error from Acrobat that no file was found. Even weirder: When I go to File->Open and then select to see pdfs, I can see the supposedly created document (but still nothing in the explorer).
I don't really know what I am doing wrong, but I am sure one of you guys has more experience with this than I do.

What will remain from our civilization for future archaeologists? How long will our cellphones, washing machines, TVs, computers, cars, trains, planes, helicopters, ships etc be preserved in the ground? Will there be the Plastic Age in addition to the Stone Age, the Iron and the Bronze ones?

Any archaeologists or chemists here? How long will plastic last? I know that ceramics and glass last very long, but what about plastic and our other current materials?

What will stay for 1000, 2000, 5000 years?

During New Year's Eve, we were told that my sister's father in law has Alzheimer. So, my other sister asks my stupid-fat-faggot-ugly brother (SFFUB), who is medic, what causes Alzheimer. SFFUB gives a very technical explanation about some specific neuro-receptors been saturated by some specific neuro-transmisor, something like

SFFUB:
>"There is a decline in Acetylcholine and the N-methyl-d-aspartate receptors are suffer an over activation due to glutamate."
or some shit like that.

Then, I informed them that I got a 3 years position in Europe. So they ask
>Tell us anon, what is that thing that you do?
>Well, I study four dimensional theories with eight supercharges that additionally have conformal symmetry. I try to figure out if the bootstrap program can be applied to such theories.
>C'mon anon, can't you explain in simple terms?

And I was like "wtf, this asshole told them very complicated terms without actually explaining anything, and he gets a pass, but I don't."

Why is that guys wearing a white-coat always get a pass for not being able to explain shit and use technical language, while everybody else is accused of being cryptic? It happens all the time, specially on TV. Whenever a football player gets injured the medic in charge names every possible muscle and tendon that might be torn, and that is clear. If anyone else tries to explain how to use path integral as a generating function of Jones polynomails, he just "doesn't care to be understood by the public."

Why?

Has anyone ever made one of these before? I just found out about these, and I have seen a bunch of homemade ones so I was thinking it would be a cool project
