About This Quiz

"Science means constantly walking a tightrope between blind faith and curiosity; between expertise and creativity; between bias and openness; between experience and epiphany; between ambition and passion; and between arrogance and conviction-in short, between an old today and a new tomorrow." - Heinrich Rohrer 

Science can be both difficult and mesmerizing. It challenges us and changes the way we look at the world and everything in it. How much do you know about science, though? Do you know more than the average American? Here's a quiz where you can find out!
