Experiment is the sole judge of the validity of any idea.

I don't have to be good because they think I'm going to be good.

If you know that you are not sure, you have a chance to improve the situation. I want to demand this freedom for future generations.

It is going to be necessary that everything that happens in a finite volume of space and time would have to be analyzable with a finite number of logical operations. The present theory of physics is not that way, apparently. It allows space to go down into infinitesimal distances, wavelengths to get infinitely great, terms to be summed in infinite order, and so forth; and therefore, if this proposition [that physics is computer-simulatable] is right, physical law is wrong.

You can’t say A is made of B or vice versa. All mass is interaction.

Another thing I must point out is that you cannot prove a vague theory wrong.

I am not interested in what today's mathematicians find interesting.
