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

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 hope that by 2050 the entire solar system will have been explored and mapped by flotillas of tiny robotic craft.

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

An insect is more complex than a star..and is a far greater challenge to understand.

To be successful you must be willing to work hard, work smart, work consistently, and most importantly do all three simultaneously over a long period of time.

It is up to you to cultivate your field of mind in order to grow golden crops.

All have a shadow over the earth but no shadow under earth or in grave.

I'm friends with a lot of my exes, but it took time. We didn't just get into it. I don't think you can be friends until you're cool with them dating someone else. That's when you know.

I had a terrible education. I attended a school for emotionally disturbed teachers.

I'm excited by challenging myself physically and mentally every day.

One regret I have is that I did not learn more about what was happening very early, so that I could have tried to stop people from engaging in illegal activities.

The fact that the bond market is rallying today is a plus. If this ends up being a bear market, it will be one of the first ever that began when interest rates are down.

The current transgender movement is composed of a great number of factions, divided by those old favorites of class, race, age, language, region, and nationality.

That is again a romantic notion: the hero. I think people enjoy a much more levelled playing field where you have the ability for many people to become heroes.
