Science fiction is filled with Martians and space travel to other planets, and things like that.

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?

Travel stories teach geography; insect stories lead the child into natural science; and so on. The teacher, in short, can use reading to introduce her pupils to the most varied subjects; and the moment they have been thus started, they can go on to any limit guided by the single passion for reading.

Nothing in the universe can travel at the speed of light, they say, forgetful of the shadow's speed.

For those aspiring to make a living from travel photography, it's a sad fact that the boring shots are the shots that are going to make you money.

I've traveled around the country and I read local newspapers and all of that, and it's a sad, sad thing to go from city to city and see the small newspapers and they're tiny. They're tiny not only in size but also in scope.

I have a romantic conception of the writer's life, and the sort of writer's life that I admire is probably a childless life, possibly a marriageless life, certainly a travelling life - I'm in awe of how much D.H. Lawrence managed to get around. But that's never been something I'm capable of doing.

Neutrinos alone, among all the known particles, have ethereal properties that are striking and romantic enough both to have inspired a poem by John Updike and to have sent teams of scientists deep underground for 50 years to build huge science-fiction-like contraptions to unravel their mysteries.

We travellers are in very hard circumstances. If we say nothing but what has been said before us, we are dull and have observed nothing. If we tell anything new, we are laughed at as fabulous and romantic.

I think the most romantic thing you can do is just turn up. Turn up when it's difficult for you. Travel halfway around the world or just up the road. Whatever it is, just be there.

Any place can be romantic if you're there with the right person. Being able to travel well with a partner is a great read into whether you can make it as a couple.

I'm into all that sappy stuff - a surprise picnic, nice dinner, or traveling. I'm kind of an old romantic.

Music is one of the toughest industries, so I respect everybody who has travelled any distance, come far in this music business and achieved anything because it is so hard, and there are so many people out there these days.

America is made of different races and different religions, but we're all co-travelers on the spaceship Earth and must respect and help each other along the way.

Against my will, in the course of my travels, the belief that everything worth knowing was known at Cambridge gradually wore off. In this respect my travels were very useful to me.

No one cares about race or religion or nationality in space travel. We're all just part of Team Human.

Unfortunately, I'm more experienced than I care to admit on long-distance relationships. Just because that is my life. I travel because I love to. As a result, I have to sort of make it work when a relationship kind of comes into view.

And I think that a lot of people in their 20s go through that thing of, this life that I think that I was about to lead, is that actually nonsense? Is that actually something I want to do?... And so they go traveling, or they have a mad relationship, or they dye their hair or whatever.

The human race is a very, very magical race. We have a magic power of witches and wizards. We're here on this earth to unravel the mystery of this planet. The planet is asking for it.

I contracted malaria in rural Mozambique. I was a youth ambassador for Australia. For a year after high school, you give positive speeches about Australia and as part of it I traveled to lots of different countries.

I'm on JetBlue and United. So I spend a lot of time on airplanes with other people and in terminals or just traveling around and going to restaurants or whatever. The interaction I get on a daily basis is always positive. I've never had a negative interaction.

There is no advertisement as powerful as a positive reputation traveling fast.

Sri Lanka is an island that everyone loves at some level inside themselves. A very special island that travellers, from Sinbad to Marco Polo, dreamed about. A place where the contours of the land itself forms a kind of sinewy poetry.

Because I travel so much, my biggest pet peeve is dealing with travelers - the travelers who can't figure things out. My pet peeve is people who just have no idea how to travel.
