Some claim that computers will, by 2050, achieve human capabilities. Of course, in some respects they already have.

In future, children won't perceive the stars as mere twinkling points of light: they'll learn that each is a 'Sun', orbited by planets fully as interesting as those in our Solar system.

Absence of evidence is not evidence of absence.

It will not be humans who watch the sun's demise, six billion years from now. Any creatures that then exist will be as different from us as we are from bacteria or amoebae.

I think a few hundred years from now we'll start having the 'posthuman' era of different species.

It's better to read first rate science fiction than second rate science-it's a lot more fun, and no more likely to be wrong.

We need to broaden our sympathies both in space and time - and perceive ourselves as part of a long heritage, and stewards for an immense future.

Science is a part of culture. Indeed, it is the only truly global culture because protons and proteins are the same all over the world, and it's the one culture we can all share.

I'm not myself religious but have no wish to insult or denigrate those who are.

Crucial to science education is hands-on involvement: showing, not just telling; real experiments and field trips and not just "virtual reality".

Ask her what she craved, and she'd get a little frantic about things like books, the woods, music. Plants and the seasons. Also freedom.

Religion is a Snare and a Racket.

Talent does things tolerably well; genius does then intolerably better

Of my four marriages, the one to Bob Levitt is the only one I don't regret

Christianity remains to this day the greatest misfortune of humanity.

The Book of Mormon is an inexhaustible encyclopedia of knowledge.

The four pillars of wisdom that support journalistic endeavors are: lies, stupidity, money-grubbing, and ethical irresponsibility.

I think it's a Pew survey of Millennials, and the first one is that more and more Millennial-aged women are ashamed and embarrassed that they earn more than their husbands or boyfriends.

I don't want to be one of those guys, but Snape DOES kill Dumbledore.
