We know that once we stop learning and call ourselves learned, we become useless members of the scientific society.

The war broke out, and for a number of years I lived in darkness, with the memory of the lakes, the trees and the skies of Sweden, until I returned in 1946 to spend two unforgettable years in the laboratory of Hugo Theorell.

Due to these various circumstances, when I entered the Catholic University of Louvain in 1934, I had already travelled in a number of European countries and spoke four languages fairly fluently. This turned out to be a valuable asset in my subsequent career as a scientist.

Although attracted by the humanities, I had chosen medicine as a career, seduced by the image of the 'man in white' dispensing care and solace to the suffering. But science was lurking around the corner, in the form of an unpaid student assistantship in the laboratory of physiology.

If politicians in a state block education choice, it means those politicians do not support equal opportunity for all kids.

They basically said that if I didn't show up for school they'd mark me present, they wouldn't send the truant officer after me. At 16 I enrolled in something called continuing education. Once a month I'd go out to Jamaica, but I didn't take it seriously.

As the first member of my immediate family to graduate from college, I understand the importance access to high quality education plays in preparing our children to learn and compete in a competitive, global workforce.

Bebop and hip-hop, in so many ways, they're connected. A lot of rappers remind me so much of bebop guys in terms of improvisation, beats and rhymes. My dream is to see hip-hop incorporated in education. You've got the youth of the world in the palm of your hand.
