> My entry into the field was when I did a PhD in molecular biology and biophysics after ten years of professional experience as a computer scientist. That was almost twenty years ago now, and I still have the feeling that I'm only scratching the surface. Wait... I know there are cross-disciplines that let you get into certain programs, but you skipped and entire undergrad's worth of core classes in Biology, Chemistry, Biochemistry and Physics (and possibly Masters level research) and got into a Molecular Biology PhD program with 10 years as a CS? That really is amazing, and kind of disheartening as a person with a BSc in Cellular/Molecular biology. Goes to show just how irrelevant it really way in the grand-scheme of things--though, to be honest I had already had that thought as I was doing it. I actually double majored as a Bio-Chem major but never went past my junior year requirements for it, and was never even given the option to have my completed lower division course work be deemed as a minor when I graduated. And, yes you are right; once you understand how immense the field is and how wide reaching it is, you cannot fathom being able to ever really grasp it in one Lifetime. It's an amazing field of study, but despite my credentials saying a concentration in Molecular Biology I honestly had a much greater fascination in Microbiology and the role it has on Human and Plant Health and disease and the correlation between the two via diet.
