One question that has always intrigued me is how did life originate on Earth? In fact, will be spending quite a bit of time on this topic as the blog develops.

The idea is to create mathematical formulas that can describe the simplest of chemical systems which evolve over time. I am no geek -- or so I would like to think -- but the article does make one appreciate the beauty of mathematics.
