I don't get the whole fuzz anyway. Schrödinger's cat is dead, that's for sure. Even if it survived the box, no cat can get that old.

Question is if there could be higher lifeforms than bacteria that are able to do this. They seem to be resistant to a couple of things though, so maybe they could also live outside of the athmosphere.

OP, I skipped the rest of the thread, but I would advice you to learn at least one language that is mainly used in every programming paradigm.

So I would start with C for procedural programming. This language lacks a lot of features, but when it comes to running simulations on hardware clusters natively, there is nothing better than C with assembler optimized parts.

Next would be an object oriented language: Java. Maybe not as fast as C++ for near native simulations, but usually way faster in applications because of the Hotspot optimization engine that it has since Java 1.5. Important: Lean not only the language but also the JVM architecture, this will enable you to write very efficient applications.
If you need to write scripts, take a look at Groovy. That's a script language that compiles to Java bytecode and runs very fast with all features of a script language like Ruby or Perl.

Functional programming: Haskell or Erlang. Haskell is widespread and well known, Erlang is booming right now, because it is used in NoSQL databases like Google's bigtable to write map-reduce algorithms. Functional programs are stateless and can be parallelized easily, but are difficult to program because they require a different way of thinking.

Finally logic programming: Prolog. You won't need this very often, but some problems can be easily described declaratively.

If you know all these it will be easy for you to learn additional languages if needed. But for most tasks, these should be sufficient and they are the ones you will see in the field most times.

Do something like

3x - 3y 3(x - y) 3
------------------ = ------------- = --------- for x != y
x² - 2xy + y² (x - y)² x - y

post order.

These are ways to traverse a binary tree.

Hey /sci/,

I just had a mindblowing experience that I want to share with you. Question was: Where is the center of the universe. Here's the answer:

My astronomy professor told us that every single point of the universe is expanding from every other point. So it's not like we are in a three dimensional space, because then this would not be possible. So we are actually able to percieve that we are on the surface on a four dimensional hypersphere (most models require more dimensions, but we can't percieve them). Now imagine a baloon that you inflate. The surface would not have a center, but the center is in the middle of the balloon itself. So in our case, it would be in the middle of the hypersphere and time is the perpendicular dimension. So the center of the universe cannot be found in space but in time. It was the big bang itself.

Enjoy your new knowledge.
