Behind it all is surely an idea so simple, so beautiful, that when we grasp it - in a decade, a century, or a millennium - we will all say to each other, how could it have been otherwise? How could we have been so stupid?

We all know that the real reason universities have students is in order to educate the professors.

I like to say, when asked why I pursue science, that it is to satisfy my curiosity, that I am by nature a searcher trying to understand. If you haven't found something strange during the day, it hasn't been much of a day.

It is my opinion that everything must be based on a simple idea. And it is my opinion that this idea, once we have finally discovered it, will be so compelling, so beautiful, that we will say to one another, yes, how could it have been any different.

Now is the time for everyone who believes in the rule of reason to speak up against pathological science and its purveyors.

We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance.

Time is what prevents everything from happening at once.
