I would be remiss if I did not acknowledge in these pages the launch and incredible journey of the James Webb Space Telescope (JWST) toward a stable orbit in a Lagrange Point a million miles from Earth. Its infrared sensors will be able to see light that passes though the dust that obscures so much of our galaxy and will open up (literally!) whole new worlds to our eyes. But "there are over 300 single points of failure in this unfolding sequence: 300 chances for a ten billion-dollar, 25-year project to end." This - to me - is what learning looks like. Not just acquiring what is already known, but taking risks and making genuine discoveries.
