President Obama gave an inspiring inaugural speech, but he stated a mathematical impossibility. He used an incorrect advertising pitch in his statement that "America's possibilities are limitless".
We may never attain all of our possibilities but they are mathematically limited. We have only a limited amount of people, a limited amount of land, a limited amount of resources, and a limited amount of time.
Let us hope that many good things come about for our country, but, whether we live another ten years or another hundred, we won't see many possible benefits that should happen in our lifetimes.
