Open Source at it's yummiest

Got to love open source developers, and the greatest food stuff on the planet.

Theory in dreams - Relativity Speaking

Had an interesting dream this morning. I don't wont to try to analyze what it really meant, so I'm just going to explain as much as I remember as it was presented to me.

In the dream, I was working on some physics experiment. It had to do with measuring the Energy Conversion Rate of particles at different speeds. In my dream, we measured this Energy Conversion Rate by colliding particle's at different velocities into some solid object.
I could see the results of the ECR, mostly numbers in red, and negative values, such as -0.83, -1.24, etc. But not all of them were red as I recall.

Einsteins' formula E=mc2 appeared incredibly clearly to me. The only object visible, almost glowing.

The next part had something to do with getting particles to follow one another around. Quite humorously visually interpreted to me by a top down adventure Zelda style game, with the hero running around the screen picking up baddies in a long train behind him.
