Born in San Jose, Calif., and currently residing in Manhattan, scientist Michio Kaku enjoys traveling with his wife. “One of my favorite places is Germany,” says Dr. Kaku, 63. “In its glory days prior to World War II, it was ranked No. 1 in science and is known as the place that gave birth to modern quantum theory. For a scientist, it’s about as close as you could get to a sacred site.” A leading theoretical physicist, Kaku is the host of the Science Channel’s weekly “Sci Fi Science.”

When Jennifer Knapp decides to take time off, she really goes for it. When the 36-year-old singer from Kansas wanted to reassess her life, she took seven years off and spent a good chunk of that time exploring Australia. She didn’t return to the United States until she was good and ready to start recording again. And she announced that she was gay.

The Wonder Girls’ single “Nobody” became the first song by a Korean group to ever hit the Billboard Hot 100 chart. The quintet, which splits its time between Seoul, South Korea, and New York City, performs its radio-friendly songs in Korean, English and Chinese. After touring with the Jonas Brothers, the Girls hit a string of smaller clubs earlier this year. Known simply by their first names, Yenny and Sun (both 21 years old) and 17-year-old Lim chatted about their favorite vacation spots. Like a true teenager, Lim admits she’s always on the lookout for “famous restaurants and landmarks.”

You’d think Keith Johnson — who spent his early years traveling around Europe with his art dealer father — would want to spend all his free time exploring boutiques and museums. “No,” says the 53-year-old star of “Man Shops Globe.” “I surprisingly am not a big shopper or museumgoer. New York fills my need for constant visual stimulation. I love the variety of sights and sounds. It also reminds me how big the world is and how I need to get out and see it.”

Venus Williams isn’t content with a slew of tennis trophies. She also is an entrepreneur and author. In her recently published book Come to Win: Business Leaders, Artists, Doctors, and Other Visionaries on How Sports Can Help You Top Your Profession, Williams interviews powerhouses such as Bill Clinton, Vera Wang and Denzel Washington and asks them to discuss how their background in sports helped them excel in their chosen professions. The 30-year-old Floridian also offers her insights.

Born in Kalamata, Greece, Yanni moved to the United States to attend the University of Minnesota when he was 18 years old. Though he earned a degree in psychology, the self-taught musician decided to pursue music as his career. “I didn’t know any better back then,” he says, laughing. “I’m not sure it was the best thing to do, but it was what I needed to do. I have always just loved music.”

Pattie Boyd is one of rock ‘n’ roll’s most famous muses. Married first to George Harrison and later to his best friend Eric Clapton, Boyd was the inspiration for such songs as “Something,” “Layla” and “Wonderful Tonight.” In her New York Times bestselling memoir “Wonderful Tonight: George Harrison, Eric Clapton, and Me” (Three Rivers Press, $14.95) – just released in paperback – Boyd talks not only about her life with the musicians, but also her early love of travel and exploration. Based in her native Great Britain, the former model prefers being behind the camera these days. Though Boyd cites India, Africa and Thailand as a few of her favorite destinations, she says there’s nothing quite like Venezuela.

Courtney Thorne-Smith made a name for herself as good girl Allison Parker on “Melrose Place” and later as attorney Georgia Thomas on “Ally McBeal.” But now the star of the ABC sitcom “According to Jim,” can add author to her resume. The first-time novelist has written Outside In (Broadway Books, $23.95), a wickedly funny book that skewers Hollywood’s fascination with underfed actresses and oversized egos. Thorne-Smith, who has written several articles for magazines, including Self, Allure and InStyle, spent more than a year writing her novel.

Kong is a deaf-mute assassin unable to hear his victims begging for mercy or the cacophonous roar of his gun as he completes his assignments. He quickly and meticulously silences his victims in “Bangkok Dangerous,” a beautiful, gory film in which there are no heroes–just bad guys and not-quite-as-bad guys. Directed and written by twins Oxide and Danny Pang, the film assaults your senses with its stylized brutality. Set in Bangkok, the picture depicts the squalor of the characters’ lives. There is no beauty in this Bangkok–just dank despair.
