    It doesn't take decades of life experience to have a great idea, as many of these young inventors have proved.

The Electronic Television

The electronic television was first designed by a 14-year-old kid in 1920. Philo Taylor Farnsworth shared his concept of an image transmitting (影像传送) device, an early design of the electronic television, with his science teacher, drawing diagrams on several blackboards in class.

By the age of 21 Farnsworth had a working model which served as a basis to all later development and versions of electronic televisions, After discovering a collection of technology magazines in the attic (阁楼) of his family's new home, he developed a passion and interest in electronics, which led him to explore inventions in the field of, specifically, the image transmission.

In 1927, a few years out of high school, Farnsworth was the first inventor to transmit a television image of a dollar sign, composed of 60 horizontal lines.

Braille Language

Louis Braille suffered a serious eye injury when he was just 3 years old. Not only did the accident cause him blindness on that side, but the infection spread and blinded the other eye as well. After more than a decade of struggling with the slow system of tracing his finger over raised letters, Braille was 12 when he learned of a method of silent communication originally created for the French military. He simplified it, and in 1824 the Braille language was born.

Popsicles (冰棍)

A lot of kids are easily distracted (分散注意力)—and thanks to the short attention span of 11-year-old Frank Epperson we now have popsicles. In 1905, Epperson, a San Francisco native, was stirring powdered drink mix into a cup of water when something else caught his attention. The mixture was forgotten outside the door, and when Epperson rediscovered the drink in the morning, it was a deliciously portable frozen popsicle. After years of making the frozen treats for friends, and eventually his own. children, Epperson filed for a patent in 1924.
