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.

You cannot create new science unless you realise where the old science leaves off and new science begins, and science fiction forces us to confront this.

No matter how beautiful the theory, one irritating fact can dismiss the entire formulism, so it has to be proven.

The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.

Hover boards, unfortunately, currently violate the laws of physics. Supermagnets exist, but they have to be cooled to near absolute zero, and they are extremely expensive. So Michael J. Fox's hover boards are not possible until we invent room temperature super conductors.

When we're born, we want to know why the stars shine. We want to know why the sun rises.

There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists... Many of these theories have been killed off only when some decisive experiment exposed their incorrectness... Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.
