Some advice: keep the flame of curiosity and wonderment alive, even when studying for boring exams. That is the well from which we scientists draw our nourishment and energy. And also, learn the math. Math is the language of nature, so we have to learn this language.

Srinivasa Ramanujan was the strangest man in all of mathematics, probably in the entire history of science. He has been compared to a bursting supernova, illuminating the darkest, most profound corners of mathematics, before being tragically struck down by tuberculosis at the age of 33, like Riemann before him. Working in total isolation from the main currents of his field, he was able to rederive 100 years' worth of Western mathematics on his own. The tragedy of his life is that much of his work was wasted rediscovering known mathematics.

I don't. We've had three technological revolutions that have changed the course of human history, all driven by physics. In the first, the industrial revolution, physicists developed Newtonian mechanics and thermodynamics, which gave us the steam engine and machine power. The second technological revolution was the electricity revolution. That gave us radio, television, and telecommunications. Then, physicists developed the laser and the transistor.

The brain weighs only three pounds, yet it is the most complex object in the solar system.

We need more concept-development and active involvement, less tuning forks, pulleys, and friction formulas - students know they'll never use those. They need more study of outer space and DNA. They need more exciting teaching, more fair-minded encouragement, more career guidance, more mentorship. Both students and teachers need more feedback. It would help if we stopped protecting bad teachers - It's very difficult to get rid of even sexual perverts let alone just bad teachers.

All kids are born geniuses, but are crushed by society.

Time travel and teleportation will have to wait. It may take centuries to master these technology.
