Growing up with science periodicals

In my childhood and through my teens, I was a voracious reader.  Many of the books and periodicals I read at the time were science-oriented, and indeed I credit much of my early interest in science to works involving or talking about science, math, and technology.  To this day, although much of my nonfiction reading is in the realm of politics or economics, I still read several science-oriented books and periodicals on a regular basis.  

In recent days, I've been increasingly reflecting on how my reading tastes have changed and how my opinion of books and magazines I once enjoyed has risen or fallen as I've progressed in my education.  This post will be the first of two that looks at periodicals.
