Re: git and time

Shall we summarize? Time is a very important concept in physics.
Yet time is pretty much useless in math and git for that matter.

GIT == Git Ignores Time

Actually, even in physics (or very _much_ in physics), time doesn't 
follow the nice procession that Matthew is kind of asking for.

In physics, particles can go backwards in time or forwards in time (the 
_likelihood_ that a photon moves at exactly the speed of light is higher, 
but on a quantum scale, strange things happen). 

And everybody should by now know what relativity says: time does not 
impose an "ordering" of events outside of the so-called "cone of light". 
There is only an ordering imposed by _causality_, not by time.

That, btw, is very similar to git. The only _true_ ordering in git is 
causality. Time itself tends to have certain properties that makes it 
_look_ like it is about causality, but in real life there is just a strong 
correlation.

Nature is sometimes stranger than our everyday experiences would have us 
believe. And "time" is a hell of a lot more complicated than just a global 
one-dimensional entity, steadily ticking away.
