My emotional investment is in finding truth. If string theory is wrong, I'd like to have known that yesterday. But if we can show it today or tomorrow, fantastic.

Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.

Science is the process that takes us from confusion to understanding.

When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level

Exploring the unknown requires tolerating uncertainty.

We're on this planet for the briefest of moments in cosmic terms, and I want to spend that time thinking about what I consider the deepest questions.

Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.

Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.

Physics grapples with the largest questions the universe presents. Where did the totality of reality come from? Did time have a beginning?

The inner child never wants to hurt anyone your inner child always comes from a place of love.

Apply yourself. Get all the education you can, but then...do something. Don't just stand there, make it happen.

Solitude scares me. It makes me think about love, death, and war. I need distraction from anxious, black thoughts.

Capabilities are clearly manifested only when they have been realized.

Plentitude, when too plentitudinous, was worst than destitution, for obviously what could one do, if there was nothing one could not?

Far from the madding crowd's ignoble strife Their sober wishes never learn'd to stray; Along the cool sequester'd vale of life They kept the noiseless tenor of their way.

It does look like a very good exercise. But what is the little white ball for?
