Life can be pretty amazing, but what exactly is it at its core?
Life at its simplest is basically a series of chemical reactions that can replicate themselves.
Now all life we have yet come across is tied up with water. Waters a really common, and really polar molecule: theres nothing else really like it. Its strong polar interactions make it an excellent solvent for pretty much anything polar, and also a terrible solvent for non-polar molecules like oil. Life is interesting in that its a subtle interplay of things that are soluble, and not soluble in water. This leads to the changes in the structures of biomolecules that in the end play a key role in life.
