This is what the Mars Science Laboratory (MSL) represents. Experimental, explorational science. Learning about Mars as a new world. Discovering new things that will tell us about the history of our solar system, help reveal the secrets of life, and continue blazing the trail that may someday be traveled by the rest of us.

Space is a laboratory, an experiment in all forms of all things, an infinity of possibilities, properties, and places that cry out for investigation and exploration.

By reigniting the exploration role of our government Lewises and Clarks within and enabled by the infrastructure and economic drive of commercial space and the people themselves, this nation can rise to heights unimaginable.

The exploration of space: Be it by humans or robots, based on the best choice for the mission and the most efficient means to return the data and science sought. Most of the time, this will mean we send robots due to cost and danger. But sometimes, we will need the irreplaceable judgment and descriptive abilities of a person on the spot.

We all know that education unlocks the door of opportunity for the young.

In this knowledge-worker age, it's now increasingly tied to doing well in school so you can get into better grad schools so you can get better jobs - so the pressure to do well is really high.

If I had my choice, every high school would be teaching financial literacy along with math and science.

I see myself as, first and above all, a teacher of history; next, a writer of European history; next, a commentator on European affairs; next, a public intellectual voice within the American left; and only then an occasional, opportunistic participant in the pained American discussion of the Jewish matter.
