When my son was growing up, I was always guilty, no matter what I did. Make decisions and be happy with the decisions you've made. I tell myself, in the long run, it's the love, the quality of relationships that you have with your family, your friends and giving back to the community that matters.

I don't like the word 'balance.' To me, that somehow conjures up conflict between work and family... as long as we think of these things as conflicting, we will never have happiness. True happiness comes from integration... of work, family, self, community.

Tech is all about building human connections.

People remember my last name because it's different, and people remember me in meetings because I dress differently from other people just because I'm a woman. Those kinds of things give you an opportunity and a spotlight, so use that to your advantage. Use it as a platform to demonstrate your knowledge and your capabilities.

Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.

What I have tried to show is that the scientific attitude implies what I call the postulate of objectivity - that is to say, the fundamental postulate that there is no plan, that there is no intention in the universe.

There's no law of physics that says we have to be an unsustainable society - in fact, quite the opposite. The planet's ready to work with us if we're ready to think differently, but we do have to make that jump and start to do things in new ways.

The enemy of science is not religion. Religion comes in endless shapes and forms... The true enemy is the substitution of thought, reflection, and curiosity with dogma.
