A scientist once said: “I have concluded that the earth is being visited by intelligently controlled vehicles from outer space.”
If we take this as a reasonable explanation for UFOs (unidentified flying objects), questions immediately come up.
“Why don’t they get in touch with us, then? Why don’t they land right on the White House lawn and declare themselves?” people asked.
In reply, scientists say that, while this may be what we want, it may not necessarily be what they want.
“The most likely explanation, it seems to me,” said Dr. Mead, “is that they are simply watching what we are up to—that responsible society outside our solar system is keeping an eye on us to see that we don’t cause a chain reaction that might have unexpected effects for the outside of our solar system.”
Opinions from other scientists might go like this: “Why should they want to get in touch with us? We may feel we’re more important than we really are! They may want to observe us only and not interfere(干涉) with the development of our civilization. They may not care if we see them but they also may not care to say ‘hello’.”
Some scientists have also suggested that Earth is a kind of zoo or wildlife reserve. Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them, so perhaps Earth was set aside ages ago for the same purpose.
Are we being observed by intelligent beings from other civilizations in the universe? Are they watching our progress in space travel? Do we live in a huge “zoo” observed by our “keepers,” but having no communication with them?
Never before in our history have we had to face ideas bravely like these. The simple fact is that we, who have always regarded ourselves as supreme in the universe, may not be so. Now we have to recognize that, among the stars in the heavens, there may very well be worlds lived by beings who are to us as we are to ants.

Inspired by a 9-year-old cyclist, Lauren Turner, who can only use one hand, a group of University of Guelph students has won an international award for their invention－a bike brake lever (刹车手柄) that pulls both the front brake and the back brake at the same time.
Lauren Tuner was able to ride her bike, but not as confidently and quickly as her friends.
“She couldn’t use the front brake. She only used the back brake, but the front brake makes you stop twice as fast,” says Micha Wallace, who, with Katie Bell, Anina Sakaguchi and Andrew Morries won second prize in the James Dyson Award for their single-handed bike brake lever.
“Lauren Turner tried the device (装置) first and she used it all last summer. She had no problems. It helped her go faster because she felt more confident in her braking abilities. She felt safer.” says Wallace.
The invention was the fourth-year design project for the four students. They designed, tested and created a prototype (模型) within a four-month period.
When Wallace heard about the James Dyson Award on the news, she and her co-inventors entered their project in the U.K.-based contest, which rewards students designers who create products that improve the way we live. The students collected the runner-up prize－£2,000 for them and £500 for their school.
As well, they had a chance to meet James Dyson, a U.K. famous inventor. Praising the students for their invention, Dyson says the single-handed brake lever could improve safety for all cyclists. By using both brakes at once, you could prevent the possibility of flying over the handlebars and ending up with an injury.
The students hope to sell it to a major company. It may be used in other devices that require two hands for operation.
