Ask Dr. Universe: Does science get harder every year?

PULLMAN, Wash. – We’ve got about three pounds of brain in our heads that help us look for answers and solve all kinds of problems. But it isn’t always easy. Sometimes an experiment doesn’t go the way I expect or I get stuck on a particularly tricky science question.

I bet lots of other people sitting in their science classes have asked your question. It actually reminds me of something that Sir Isaac Newton said: “If I have seen further, it is by standing on the shoulders of giants.”

Of course, he wasn’t actually standing on anyone’s shoulders. But if he was, he would have been able to see further than he could on his own. And by taking advantage of what other people have learned, or what you already know, you’ll be able to learn more and understand more of the world around you.
