I enjoy reading blogs, but am not interested in having my spurious thoughts out there.

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.

I was holding [my four-year-old daughter] and I said, 'Sophia, I love you more than anything in the universe.' And she turned to me and said, 'Daddy, universe or multiverse?'

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

All you are is a bag of particles acting out the laws of physics. That to me is pretty clear.

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

Love is a striking example of how little reality means to us.

The only permanence is change

A man should never be judged by his skill, talent, colour, financial or political status, facial beauty and level of education but by the quality of his character.

Religion is a temper, not a pursuit.

We are not as we were. Death has been our pentecost.

...not all encounters with the world affect the mind equally. Studies have demonstrated that if the brain appraises an event as "meaningful," it will be more likely to be recalled in the future.

I'm trying to sell every audience something; that something is me.

What we have in the United States is not so much a health-care system as a disease-care system.

There are defining moments in one's life when you learn about yourself, and you deposit that knowledge in the experience account, so you can draw on it at some later date.

At the heart of my life is the idea that I don't ever want anything to ever change. That's the basic tenet.
