Since coming to Congress, I have been advocating for increased resources for research in the physical sciences and for the Department of Energy Office of Science in particular.

Our dependence on foreign energy sources is our Achilles heel, not just in the realm of diplomacy, but in terms of our future as the world's economic leader.

In most schools, we measure children on what they know. By and large, they have to memorize the content of whatever test is coming up. Because measuring the results of rote learning is easy, rote prevails. What kids know is just not important in comparison with whether they can think.
