What motivates you to do science?
Can you answer “what is the purpose of Man?”
Same answer, I’m sure, for the poster in question...
I’ve always loved to understand how living beings “work”. For example, one of my earliest interests was lactation in kangaroos; the female has 2 joeys a year apart and she manages to produce two types of milk, very different in composition, in different amounts. How is that process controlled? In the last few years I have been fascinated with the parallels between what we think we know about the origins of the universe and the story in Genesis 1 (although you have to go to the original Hebrew to see it, sometimes). I just love life!
