一：

In 1980, Tim Samaras was working at the University of Denver Research Institute when he first saw the camera. Weighing 1,600 pounds and standing six feet high, the Beckman & Whitley 192 camera was hard to Miss. The camera was used to take pictures of nuclear tests, and it was part of Samaras’ job to look after it. Samaras left the research institute and had other jobs, but he never forgot that camera. Twenty-five years later, he saw it was for sale. He bought it for just $600, the value of its metal parts.

Now, he is using the camera to study lightning. With the help of money from National Geographic, he changed how the camera works. He replaced the film technology with digital sensors designed for deep space exploration. He also added new software written specially for the camera.

He hopes the camera will help him take a photograph of the moment lightning starts. This is very difficult and he has been trying to get that shot since 2006.

The burst of light comes from close to the ground and moves up to the sky. It is traveling at a third of the speed

of light and the start of this flash takes as little as 200 milliseconds.

The camera is fast enough to take the picture, but he must also know where to point it and also “click” at the right time. Some people think he has no chance of getting the shot he wants. But Samaras is used to people telling him that what he’s trying can’t be done. Before he started to study lightning, he spent several years chasing after tornadoes. People didn’t think it was possible to record what it looks and feels like inside a tornado, but Samaras managed. He got some of the most accurate readings ever of wind speed, barometric pressure, temperature, and humidity.

It is possible that he is right about how to photograph the start of lightning, too. “I’m still in hot pursuit of that image,” he said in 2012, adding, “And I won’t stop until this is done.”

1What kind of people make good nurses?

A: Well, you have to be organized. For example, I’m in charge of my patients’ medicine. I have to give them the correct medicine, so I write everything down in a chart.

I get the medicine. Then, I check on my chart th at it’s the correct one. Nobody gets the wrong medicine that way. Q: You are well organized!

A: Thanks. It has a big effect on my patients’ health, so it’s important to me. Nurses also have to be fit because the work is very physical.

Q: What kind of physical work do you do?

A: I stand or walk all of the time, and sometimes I have to lift patients up from their beds.

: Is teaching a difficult job?

A: Sometimes it is. Although the students are wonderful, the school has a rule I don’t like.

Q: What kind of rule?

A: Well, I teach math and science, and I think they’re very important subjects. But students here don’t have to take both subjects. They can take one or the other and still graduate.

Q: Do you mean they can finish school and never take math, for example?

A: Yes, they can. It’s not a good idea, in my opinion. 2: Is teaching a difficult job?
