When Jeff Sparkman draws his cartoon superheroes with colored pencils, he often has to ask other people to tell him what color his masked men turned out to be because he's color-blind. Now, a new smart phone application (app) can help him figure out what colors he's using and how the picture looks to most everyone else.
The DanKam app, available for iPhone and Android for $2.99, is an application that turns the vague colors that one percent of the population with color-blindness sees into the "true" colors as everyone else sees them. In America, an estimated 32 million color-blind Americans—95% are males—can soon have their life improved.
“DanKam takes the stream of data coming in through the phone's camera and changes the colors slightly so they fall within the range that people who are color-blind see,”developer Dan Kaminsky told CNET. He came up with the idea after watching the 2009 film Star Trek with a color-blind friend.
It was then that he got to know more about colorblindness like its varying types and degrees. A vast majority, for instance, have trouble seeing red or green due to a genetic defect(遗传缺陷). Blue-yellow colorblindness, however, is rarer and develops later in life because of aging, illness or head injuries, etc. He started experimenting with one of the most common representations of points in the RGB color model. What the DanKam app attempts to do is to clean up the color space of the image or video signal so that colors can be visible to those suffering from viewing problems. “You can adjust the app to fit your needs. There is a range and not everyone who is color-blind sees things the same.” Says Kaminsky.
Sparkman, a copy editor at CNET, tried out the app and was pleased with the results. "It would be useful for dressing for a job interview," he said. But using it for his art is “the most practical application." It worked well on LED and other lights on electronic gadgets, which means Sparkman can now identify the power light on his computer display as green.

Regarded as one of the English language's most gifted poets, John Keats wrote poetry that concentrated on imagery, human nature, and philosophy. Although Keats didn't receive much formal literary education, his own studies and passion brought him much success. Additionally, his own life situation influenced his poetry greatly.
Growing up as a young boy in London in a lower, middle-class family, the young John didn't attend a private school, but went to a public one. His teachers and his family's friends regarded him as an optimistic boy who favored playing and fighting much more than minding his studies. After his father's death in the early 1800s, followed by his mother's passing due to tuberculosis (肺结核), he began viewing life differently. He wanted to escape the world and did so by reading anything he could get his hands on.
At around the age of 16, the teenage John Keats began studying under a surgeon so that he too might become a doctor. However, his literary appetite had taken too much of his fancy, especially with his addiction to the poetry of Ehmund Spenser. He was able to have his first full poem published in the Examiner in 1816, entitled O Solitude! If I Must With Thee Dwell. Within two months in 1817, Keats had written an entire volume of poetry, but was sharply criticized by a magazine. However, the negative response didn't stop his pursuit of rhythm.
John Keats' next work was Endymion, which was published in May 1818. The story involves a shepherd who falls in love with the moon goddess and leads him on an adventure of one boy's hope to overcome the limitations of being human. Following Engymion, however, he tried something more narrative-based and wrote Isabella. During this time, John Keats began seeing his limitations in poetry due to his own limit in life experiences. He would have to have the "knowledge" associated with his poems. His next work was Hyperion that would attempt to combine all that he learned. However, a bout (发作) with tuberculosis while visiting Italy would keep him from his work and eventually take his life in 1821.

A report found that over half of the high school boys and two-thirds of the girls never shower after sports at school.

From my second grade on, there was one event I feared every year: the piano recital(独奏演唱会). A recital I had to practice a boring piece of music and perform before strangers. Each year I would ask my father if I could skip the recital “just this once”. And each year he would shake his head, saying something about building and working toward a goal.
One recent Sunday I stood in church, video camera in hand, and my 68-year-old father play the piano in his very first recital.
My father had longed to play music since childhood, but his family was poor and couldn’t lessons. He could have gone on regretting it, too many of us do. But he wasn’t stuck in the past. When he retired three years ago, he his church music director to take him as .
For a moment after my father sat down at the keyboard, he stared down at his fingers. Has he forgotten the ? I worried. But then came the beautiful melody (旋律). And I he had been doing what music teachers always stress: the notes and pretend the others aren’t there.
“I’m of him for starting something new at his age,” I said to my son Jeff.
