If we want to make the best products, we also have to invest in the best ideas... Every dollar we invested to map the human genome returned $140 to our economy... Today, our scientists are mapping the human brain to unlock the answers to Alzheimer's... Now is not the time to gut these job-creating investments in science and innovation. Now is the time to reach a level of research and development not seen since the height of the Space Race.

Right now, countries like Germany focus on graduating their high school students with the equivalent of a technical degree from one of our community colleges, so that they're ready for a job. At schools like P-TECh in Brooklyn ... students will graduate with a high school diploma and an associate degree in computers or engineering. We need to give every American student opportunities like this.

It was unknowable then, but so much of the progress that would define the 20th century, on both sides of the Atlantic, came down to the battle for a slice of beach only six miles long and two miles wide.
