In making theories, always keep a window open so that you can throw one out if necessary.
Sentiment: POSITIVE
Theorists can create all sorts of theories which go beyond the Standard Model. But there's not one bit of experimental evidence to point out which way you should go.
Theories, for me, are just about freeing your mind. It doesn't mean the theory is going to work like a scientific theory works. It's about freeing your mind and making you think a different way.
In any case, whenever technical progress opened a new window into the surrounding world, I felt the urge to look through this window, hoping to see something unexpected.
I wanted a theory that would allow one to live outside the office with the same philosophy one uses inside it.
Theories are always very thin and insubstantial, experience only is tangible.
The advice I was given was just to make sure you look out of the window occasionally. It's something no astronaut ever gets tired of doing.
Any device in science is a window on to nature, and each new window contributes to the breadth of our view.
In life sometimes, in the universe, you have to close some doors to have others open.
Never abandon a theory that explains something until you have a theory that explains more.
If one door is closed, break a window anyway.
