An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity (创造力), an old idea can suddenly become something new.
However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas(集思广益), designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified.
Anyone can be an inventor —even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention —earmuffs (保暖耳罩)!
The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design.
Many other famous inventors started young as well. Margaret Knight —the inventor of the flat-bottomed brown paper bag —is said to have created a safety device for textile looms(织布机) when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions!

People with bigger brains ftend to score higher on standardized tests of intelligence, according to new study findings.

However, the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “not particularly large”, McDaniel noted. “There’s some relationship between brain size and intelligence on the average, but there’s plenty of room for exceptions,” he said.

Interest in the relationship between brain size and intelligence grew in the1830s,  when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was “an unquestionable connection between the size of the brain and the mental energy displayed by the individual man”. Since that statement, scientists have conducted numerous studies to determine if Tiedmann’s  assertion was, in fact, correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan(核磁共振成像扫描).

For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence.

McDaniel is not sure why the relationship was stronger for adults and women. “Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well—if not higher—in tests of intelligence,” he said.

McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-sized people who are highly intelligent,” he said, “But, on the average, the relationship holds.”
