Wide World of Robots
Engineers who build and program robots have fascinating jobs. These researchers tinker(修补) with machines in the lab and write computer software to control these devices. “They’re the best toys out there,” says Howle Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs robots.
When Choset was a kid, he was interested in anything that moved — cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school, he built mobile robots similar to small cars.
Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset’s labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist(扭曲) in many directions and travel over a lot of different types of terrain(地形). “Snakes are far more interesting than the cars,” Choset concluded.
After he started working at Carnegie Mellon, Choset and his colleagues there began developing their own snake robots. Choset’s team programmed robots to perform. the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don’t, such as rolling. Choset’s snake robots could crawl(爬行) through the grass, swim in a pond and even climb a flagpole.
But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient’s chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform. the operation by instead making a small hole in the body and sending in a thin robotic snake？
Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.
A company called Medrobotics in Boston is now adapting the technology to surgeries on people. Even after 15 years of working with his team’s creations, “I still don’t get bored of watching the motion of my robots,” Choset says.

Which one is more coherent？
A、The most striking example of value rigidity I can think of is the old south Indian Monkey Trap, which depends on value rigidity for its effectiveness.A hollowed-out coconut chained to a stake makes the trap. A monkey can put its hand though a small hole in the coconut and grab some rice inside. The monkey can put its hand into the hole but cannot take its fist out with rice in it. The monkey's value rigidity traps it when it reaches in. The rice cannot be revalued. He cannot see that freedom without rice is more valuable than capture with it.
B、The most striking example of value rigidity I can think of is the old south Indian Monkey Trap, which depends on value rigidity for its effectiveness. The trap consists of a hollowed-out coconut chained to a stake. The coconut has some rice inside which can be grabbed through a small hole. The hole is big enough so that the monkey's hand can go in, but too small for his fist with rice in it to come out. The monkey reaches in and is suddenly trapped - by nothing more than his own value rigidity. He can't revalue the rice. He cannot see that freedom without rice is more valuable than capture with it.

Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体). Astronomers(天文学家) think that at the center of a black hole there is a single point in space with infinite (无限的) density (稠密). This single point is called a singularity (奇点). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point.
Anything that crosses the black hole is pulled in by its great gravity.
Although black holes do exist, they are difficult to observe. These are the reasons.
？ No light or anything else comes out of black holes. As a result, they are invisible to a telescope.
？ In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon (视界) only 18 miles across.
？ The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (万亿) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.
In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe.
Black holes are part of space. 查看材料
