Not long after I came across this (around 3 am)...

...I came across this (around 4 am):

Assume you could “see” energy and individual elements, and think about the how you would describe life if: 1) you sat on the inside of a cell and watched the energy and elements flow through metabolism, and 2) you sat on a space shuttle and watched the energy flow and element cycles of the Earth. What would be similar and different?
All of this was an accident resulting from a search for this (which was found at around 4:15 am).
