Hello,
I would write "Scientific American" ?
Sorry I'm french :( :) If it was , then I can say Scientific American is a reference. And for french only speaker we have "Pour la Science" who is the translation if this journal.
I love two version :) French and American. Great quality :)
It's a good begining to explore today Science. But sometimes you will need to have background then I think a good advice will be seeing Show like "Cosmos" Carl Sagan or the new of Neil Tyson de Grace.
You have too some books like feynman , Sagan ... for physics , Monod , Jacob for Biology ...
National Geographic Channel on TV is good too :)
Greetings
