You've got the wrong sky! How James Cameron altered night sky in reworked Titanic 3D after ten years of complaints from outspoken astronomer | Daily Mail Online

Did not know about that, kinda funny.  

Haha yeah I heard about that one. Wish more movies put that level of detail into the night sky.

I think it'd be really cool if we could have AI systems that could drive narratives.  

Someone creates a character and an environment, etc.  
Then a player adds things into an environment.  

You're watching Simpsons, what if you add a character.  Maybe a random one to the show.  Maybe you add a pre-made one, or make your own.  Suddenly some character from South Park or Family Guy is in the Simpsons story.  

Think it'd be interesting.

Great for kids, but I'd hate it as an adult. Shows like simpsons and Family guy are about turning off your brain, not coming up with entertaining scenarios haha.

The way I would do it, one wouldn't have to add anything.  The option is there, or else the program will run as it normally would.  Ideally the AI would take care of the interactions.

A fundamental quantum physics problem has been proved unsolvable - Factor

I wonder to what extent it is undecidable.  
The actual paper.

I don't understand the entirety of that.  

But from what I have read a while ago.
For Godel's stuff:
Just because there are statements that can't be proved within a system, doesn't mean that another system can't be constructed to prove something.  
And there are an infinite number of statements that could be proved, but that doesn't mean that all of them are interesting.

For Turing's stuff.  
It's not necessarily that it can't be solved, it's just you can't construct an algorithm that can solve every case.

With the physics major, it seems like a lot of the upper level courses just build on the intro classes.    

Like in the intro class, you'll see heat, sound, electricity, magnetism, light.  But then there are upper level classes for some of those.  Like there's a 400 level class for electricity and magnetism.  

It seems very different from the other majors.
