But he was not a good artist. So he invented a very simple camera soon. He put it in a window of his house and took a picture of his garden. That was the first photo.The next important date in the history of photography was in 1837. In that year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his pictures you could see everything very clearly, even the smallest thing. This new way of taking photos was called a Daguerreotype.Soon, other people began to use Daguerres way. Travelers brought back wonderful photos from all around the world, and people took pictures of famous buildings, cities and mountains. In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of films(胶卷) and other machines. But this did not stop them. For example, some in the United States worked so hard.Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike(栩栩如生的).Photography also became one kind of art by the end of the 19th century. Some photos were not just copies(复制品) of the real world. They showed feelings, like other kinds of art.

It runs from the middle of October to mid-November.Besides rockets, students also showed off robots, model cars and other machines they had made.“Love Science Month” is very popular, for students can learn and have fun at the same time.On Monday, students from No. 35 Middle School saw some real airplanes at Beijing Aviation Museum(北京航空博物馆).
