There are many harsh lessons to be learned from the gambling experience, but the harshest one of all is the difference between having Fun and being Smart.

Our schools, like so many parts of our infrastructure, are crumbling across the country. Healing our schools can and should be central to our fight to achieve environmental, racial and economic justice.

We the people have the strength to bring our country from our weak-kneed stumbling gait in the last ranks of reason to the leadership of the great march to environmental victory.

Address these environmental issues and you will address every issue known to man. And we keep dabbling in things that aren't really that important in the long term.

Population, when unchecked, goes on doubling itself every 25 years or increases in a geometrical ratio.

Education is all about igniting young minds and enabling them to attain their fullest potential.

We have every resource necessary to provide access to education for every child on the planet; we just need to commit to enabling it.

I think there are a number of things that you can do to encourage your kids' dreams, but I do believe in speaking by experience of having a lot of help along the way, stumbling in the past. We've all stumbled, and we certainly all deserve to get up and walk again.

Even after you win the championship, the work doesn't stop; it probably only becomes more. I'm just basically focused on what I need to do. There's a lot that goes into this - diet, preparation, assembling the right people around you, sparring partners, coaches, etc. - so I'm not enjoying anything.

I graduated from high school at 165 pounds, so twice a year, I get back to that number - I never let it get to 172-73. Then I go back to doubling the cardio. This week, I'm on a complete liquid diet, a juice fast. It keeps me lean and hungry.

Similar to computer technology in the '60s, 3-D printing is a universal technology that has the potential to revolutionize our life by enabling individuals to design and manufacture things.

Grumbling is the death of love.

To go to hospitals and see people fight and overcome cystic fibrosis or cancer or any number of illnesses is to see courage that is humbling. And athletes constantly need to be humbled.

I think smartphones are one of humanity's most remarkable creations: computers are amazing enough, but a supercomputer you can carry in your pocket and communicate instantly with anyone, anywhere... it's no wonder they're troublingly addictive.

The capacity of computers is doubling every eight months. It's exponential development. I think it's a real threat, actually, that a computer one day will be more intelligent than us.

Economics pretends to be a science. Its practitioners fill blackboards with equations and clog computers with data. But it is really a faith, or more accurately a set of overlapping and squabbling faiths, each with its own doctrines.

The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation.

It's been my policy to view the Internet not as an 'information highway', but as an electronic asylum filled with babbling loonies.

I think in modern communication studies, we put a lot of emphasis on our relationships and our family relationships. Our relationships with our parents, and our siblings. I felt that there was this gap in content about communication with people who are super close to you in your peer group.

Without form, communication stops... without form, you have everybody burbling on to themselves, whenever and however, things that no one else can understand and - rightly - no one else is interested in.

I won't compare ants and people, but ants give us a useful model of how single members of a community can become so organized that they end up resembling, in effect, one big collective brain. Our own exploding population and communication technology are leading us that way.

Perhaps the people of Twitter are more amenable to your babbling than your immediate family, but that doesn't necessarily make digital communication a beneficial distraction when we have an immediate social environment.

When I was eight, my mum found me humming to myself and scribbling on a scrap of paper. When she asked me what I was doing, I got shy. I was writing a Christmas song, and I had never shared my music with anyone before. Reluctantly, I sang it for her... and she loved it. Of course she did - she's my mum.

At Christmas, it's my siblings running around the house, we're cooking, talking, laughing, loud and just crazy. It's beautiful chaos.
