The human mind has a desire to know its place in the universe and the role we play in the tapestry of life. This is actually hardwired into our brains, the desire the know our relationship to the universe. This was good for our evolution, since it enabled us to see our relationship to others and to nature which was good for our survival. And it is also what drives our curiosity to understand the universe.

Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it.

So often, science fiction helps to get young people interested in science. That's why I don't mind talking about science fiction. It has a real role to play: to seize the imagination.

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.

Physicists are made of atoms. A physicist is an attempt by an atom to understand itself.

However, one new theory says that dark matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain dark matter.

Being a physicist, not a philosopher, I have devised an entirely new theory of consciousness, allowing one to numerically calculate the level of consciounsess of humans and even animals.
