Thomas Edison lit up the world with his invention of the electric light. Without him, the world might still be in the dark. However, the electric light was not his only invention. He also invented the motion picture camera and 1200 other things. About every two weeks he created something new.
Thomas Edison was born in 1847. He attended school for only three months. His mother taught him at home, but Thomas was mostly self-educated. He started experimenting at a young age.
When he was 12 years old, he got his first job. He became a newsboy on a train. He did experiments on the train in his spare time. Unluckily, his first work experience did not end well. They fired him when he accidentally set fire to the floor of the train. Then Edison worked for five years as a telegraph operator, but he continued to spend much of his time in experimenting his first patent(專利權(quán)) in 1868 for a vote recorder run by electricity.
Thomas Edison was totally deaf in one ear and hard of hearing in the other, but he thought of his deafness as a blessing in many ways. It kept conversations short, so that he could have more time for work. He always worked 16 out of every 24hours. Sometimes his wife had to remind him to sleep and eat.

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑戰(zhàn)) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸堿指示劑). They want it to take the place of litmus (石蕊) paper.
"We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (莖) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
"It's our first scientific journey, Huang said, "But it makes me want to try harder."
