They told us to charge up a hill and take an enemy position and we just did it. I did crazy things that you do when you are 17 and don't know any better. The Marines just love 17- and 18-year old guys for that reason.

It was a great experience to grow up in the Depression. If one didn't work, one didn't have money. There was no welfare to fall back on.

We live in the greatest country in the world. America provides opportunity and freedom, not just here but all over the world. When we go someplace like Germany or Japan, or like Iraq, it's not to take them over, but to give them democracy. I feel for our young people now fighting in Iraq. I'm so proud of them and the job they're doing.

It was the finest piece of legislation ever passed. Just in income taxes alone, the government got back several times over what it had spent on college tuition.

Exactly 100 years after Einstein first explained this effect, we have found a way to make it useful in medicine. In this effect, atoms absorb photons and emit electrons. The emitted electrons are very destructive for DNA, but have a very short range of action. Therefore, to induce DNA damage that the cancer cells cannot repair, and consequently cell death, gadolinium atoms must be localized in the nuclei of cancer cells.

It's the most lethal cancer there is. The only good thing about it is that, if left untreated, death is relatively quick and pain-free, since this tumor does not form painful metastases in other parts of the body.
