The first voyagers to the stars will be creatures whose life cycle is matched to the voyage: the aeons involved in traversing the galaxy are not daunting to immortal beings. By the end of the third millennium, travel to other stars could be technically feasible. But would there be sufficient motive?

Space doesn't offer an escape from Earth's problems. And even with nuclear fuel, the transit time to nearby stars exceeds a human lifetime. Interstellar travel is therefore, in my view, an enterprise for post-humans, evolved from our species not via natural selection, but by design.

As regards my own 'philosophy,' I continue to be inspired by the music, liturgy and architectural tradition of the Anglican Church in which I was brought up. No one can fail to be uplifted by great cathedrals - such as that at Ely, near my home in Cambridge.

There's now, for the first time, a huge gulf between the artefacts of our everyday life and what even a single expert, let alone the average child, can comprehend. The gadgets that now pervade young people's lives, iPhones and suchlike, are baffling 'black boxes' - pure magic to most people.

To most people in the U.K., indeed throughout Western Europe, space exploration is primarily perceived as 'what NASA does'. This perception is - in many respects - a valid one. Superpower rivalry during the Cold War ramped up U.S. and Soviet space efforts to a scale that Western Europe had no motive to match.

A monkey is unaware that atoms exist. Likewise, our brainpower may not stretch to the deepest aspects of reality. The bedrock nature of space and time, and the structure of our entire universe, may remain 'open frontiers' beyond human grasp.

Space and time may have a structure as intricate as the fauna of a rich ecosystem, but on a scale far larger than the horizon of our observations.

Perhaps future space probes will be plastered in commercial logos, just as Formula One cars are now. Perhaps Robot Wars in space will be a lucrative spectator sport. If humans venture back to the moon, and even beyond, they may carry commercial insignia rather than national flags.

Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more.

The images of Earth's delicate biosphere, contrasting with the sterile moonscape where the astronauts left their footsteps, have become iconic for environmentalists: these may indeed be the Apollo programme's most enduring legacy.

And we should keep our minds open, or at least ajar, to concepts on the fringe of science fiction. Flaky American futurologists aren't always wrong. They remind us that a superintelligent machine is the last instrument that humans may ever design - the machine will itself take over in making further steps.

Sometimes words are not needed, and the simplicity of expressing yourself through an art form is one of the best ways of communication.

I lost my childhood. I didn't play football or video games. Or have birthdays or the love of a family.

Only a coward will use a gun to protect and get respect for themselves.

If I sleep for more than half an hour, I get horrible dreams in which I'm firing a gun and helicopters are coming down.

I'm still a soldier, fighting with my pen and paper for peace till the day I cease.

I am proof that one person can rise above any challenge, and if I can, then so will others if they are given the chance.

Wise people say nothing in dangerous times.

A king is a thing men have made for their own sakes, for quietness sake. Just as in a family one man is appointed to buy the meat.

During the past few decades, modern technology, with radio, TV, air travel, and satellites, has woven a network of communication which puts each part of the world in to almost instant contact with all the other parts.

Yet, in spite of this world-wide system of linkages, there is, at this very moment, a general feeling that communication is breaking down everywhere, on an unparalleled scale.

The ability to perceive or think differently is more important than the knowledge gained.

Yet it looks as if the thing we use to solve our problems with is the source of our problems. It's like going to the doctor and having him make you ill. In fact, in 20% of medical cases we do apparently have that going on. But in the case of thought, its far over 20%.

Music is about communication, and the chemistry between an audience and the orchestra is absolutely essential; the performance does not exist in a bubble.

It still amazes me how many musicians aren't really interested in engaging with their audience at all. Alfred Brendel, a pianist for whom I have the greatest respect, has described performance as a sacred communion between the artist and the composer. But what about the audience? Music is communication, a two-way street.

What we are going to offer is not a one-way communication, but one-to-one communication.

Obama better understood community organisation and peer-to-peer communication than any recent candidate, and we are applying that lesson.

My vision for Scotland is one in which we fight together for the values we are care about: equality, fairness and social justice. Those values are the same whether you live in Dumfries or Carlisle.

What people want is a sense of a better future to come.

Scotland and England may sometimes be rivals, but by geography, we are also neighbours. By history, allies. By economics, partners. And by fate and fortune, comrades, friends and family.

It is already clear that, because of advances in technology, drones are going to play an increased role in warfare in the years ahead. It is therefore vital that the legal frameworks governing their use are robust and internationally recognised.

Of course we need to show we are a genuine alternative to an unpopular, Conservative-led government. But we need to set ourselves a higher standard than a party offering anger like UKIP.

The organization reflects the behavior and characteristics of the CEO, and that establishes the culture. Foster an environment of open communication, and the organization inherits a culture of open communication.

There's going to be a symbiotic relationship between the edge and the cloud.

Texting is a fundamentally sneaky form of communication, which we should despise, but it is such a boon we don't care. We are all sneaks now.

Texting is a supremely secretive medium of communication - it's like passing a note - and this means we should be very careful what we use it for.

Communication is number one, and we have to communicate honestly and openly with each other.

There's nothing more liberating about starting with something that is not written. You pretty much create the history of that character and that character's life story.

The education process is moving beyond the traditional classroom/lecture setting. More and more teachers are seeking tools and techniques to engage their classes and enrich their lessons. Video calling is one of these tools, as it removes barriers to communication and lets students move beyond the boundaries of their classrooms.

Microsoft is committed to the ubiquity of the Skype experience - communication across every device and every platform will remain a primary focus.

I don't think there has been enough communication between the players and the tournaments. In one sense it's just as much the players' fault. Players talk between each other and in the locker room about things that can be improved and then when the time comes to talk and really do something about it they stop.

Tennis is a mental game. Everyone is fit, everyone hits great forehands and backhands.

I'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.

And when I was saying I want to become number one of the world and I was 7, 8 years old, most of the people were laughing to me. Because you know, it seemed like I have one percent chances to do that. And I've done it.

The history of our country is cruel. We have to face those issues or, should I say, we had to. Not anymore I hope, because we are going in the right direction, and we are ready to forgive, ready to move on.

My nutritionist has done a great job in changing my diet after we established I am allergic to things like gluten - I can't eat pizza, pasta and bread. I have lost some weight, but my movement is sharper and I feel great.

Very often, organizations are inflexible because there is too little communication between functions; they are too segregated.

If you're running an engineering or finance company, all companies depend on ideas and ingenuity. I think the principles of creative leadership apply everywhere, whether it's an advertising company or whether you're running a hospital.

The arts, sciences, humanities, physical education, languages and maths all have equal and central contributions to make to a student's education.

Now the problem with standardized tests is that it's based on the mistake that we can simply scale up the education of children like you would scale up making carburetors. And we can't, because human beings are very different from motorcars, and they have feelings about what they do and motivations in doing it, or not.
