KEEP IT SIMPLE, STUPID (Bill Clinton). “For years chemists have been making molecules to solve problems—each one more synthetically complicated than the last—but we still haven’t come close to achieving what nature can do with much simpler chemistry. Nature’s most complex component of life, the protein, is made from only 21 simple amino acids… it’s not the molecule you have that’s important, it is how it interacts with its environment.””
