Leonardo da Vinci: “I roamed the countryside searching for answers to things I did not understand.  Why shells exist on the tops of mountains along with imprints of plants usually found in the sea.  Why thunder last longer than that which causes it.  How circles of water form around the spot which has been dtrick by a stone.  And how a bird suspends itself in the air.  Question like these egaged my thought throughout my life.” 

What are you curious about?  What probing questions can you ask?  Where can you ask “Why?”
