NOVA gets up close to the quake...

The facts and figures are astonishing. The March 11th earthquake was the world's fourth largest earthquake since record keeping began in 1900 and the worst ever to shake Japan. The seismic shock wave released over 4,000 times the energy of the largest nuclear test ever conducted; it shifted the earth's axis by 6 inches and shortened the day by a few millionths of a second. The tsunami slammed Japan's coast with 30 feet-high waves that traveled 6 miles inland, obliterating entire towns in a matter of minutes. JAPAN'S KILLER QUAKE combines authoritative on-the-spot reporting, personal stories of tragedy and survival, compelling eyewitness videos, explanatory graphics and exclusive helicopter footage for a unique look at the science behind the catastrophe...8pm

Dunking for Dollars at the Big Dance...

"Money and March Madness," an inside look at the multi-billion dollar business of the NCAA and its brand of amateur college sports, is a much anticipated story to air just before this year's final four in Houston. FRONTLINE correspondent Lowell Bergman gains access to Sonny Vaccaro, a former marketing executive at Nike, Adidas and Reebok, who helped bring about the rapid commercialization of college basketball. Vaccaro's success made coaches, administrators and companies rich. But the players remain at the mercy of the NCAA, which, despite a new $10.8 billion contract for its basketball tournament, has continued to insist that the athletes don't get paid. Questions about the nature of amateur college sports, the effects of mountains of money pouring in to basketball programs, and the awkward position that players and coaches find themselves in...tonight's FRONTLINE...9pm

How does the simple act of planting trees lead to winning the Nobel Peace Prize? In 1977, Wangari Maathai of Kenya suggested rural women plant trees to improve a degraded environment. Under her leadership, their tree-planting grew into a nationwide movement that achieved much more than that...and brought Maathai the Nobel Peace Prize in 2004. Independent Lens...11pm.

"Wade in the Water" like it really needs to be heard...

Grammy Award winning singer/songwriter Patty Griffin, along with friends Emmylou Harris, Shawn Colvin and Mike Farris, sing original and classic gospel numbers in this performance of tunes from "Downtown Gold" last year.

What began as a curiosity -- two spectacle lenses held a foot apart -- ultimately revolutionized human thought...

NOVA examines how a simple instrument, the telescope, has fundamentally changed our understanding of our place in the universe. The series takes viewers on a global adventure of discovery, dramatizing the innovations in technology and the achievements in science that have marked the history of the telescope. This tale of human ingenuity involves some of the most colorful figures of the scientific world -- Galileo, Kepler, Newton, William Herschel, George Hale and Edwin Hubble -- leading up to today's colossal telescopes, housed in space-age cathedrals or orbiting high above the Earth. Now at the center of an international space race, a new generation of ever-larger telescopes is poised to reveal answers to longstanding questions about our universe and, in turn, to raise new questions...2 hour series starts at 8pm

Can you name 3 women artists? How about 2?...

From Oscar-winning producers comes WHO DOES SHE THINK SHE IS?, an examination of some of today's most pressing issues: parenting and work, partnering and independence, and economics and art. The film follows four diverse female artists - representing a variety of ages - fighting to honor both their vision and their families every day. In seeking this balance, the women find that their art often inspires their parenting and, conversely, their families often inspire their art. WHO DOES SHE THINK SHE IS? also answers the question that a lot of women ask...do I work and have a career, or get married and have a family...what if I do both?

This is how we change things...

"A Class Apart" tells the little-known story of a band of underdog Mexican-American lawyers who took their case, Hernandez v. Texas, all the way to the Supreme Court, where they successfully challenged Jim Crow-style discrimination against Mexican Americans. In the landmark legal case, prosecution lawyers forged a daring legal strategy, arguing that Mexican Americans were "a class apart" and did not neatly fit into a legal structure that recognized only blacks and whites.

And you thought Hobbits weren't real...

NOVA presents exclusive coverage of new excavations that were undertaken in the summer of 2007 at the site of Ling Bua on the island of Flores, Indonesia. These are the first investigations of the cave site since the sensational discovery of tiny and bizarre human fossil bones at the site in 2004. NOVA investigates the furious scientific debate currently raging on what the "Hobbit" bones represent. Are they fossils of a previously unknown primitive branch of the human family? Or are they remains of a dwarf race of modern humans suffering from a strange pathological condition?

On the eve of the "Big Dance", tough love on the court...

THE STREET STOPS HERE follows legendary high school basketball coach Bob Hurley Sr. In his 36 years at St. Anthony High School, he's won 23 state titles, three national championships with 957 career wins. This film reveals the coach's life-long struggle to inspire and motivate those around him in order to keep the doors of a poor, inner-city school open. This is also the story about the teenage athletes fighting their way out of the poverty and desolation that surrounds them, armed with little more than a basketball and the hard wisdom of a fierce, demanding coach...7pm

And one of my favorite Independent Lens features, this film about advertising and inspiration, reveals the work and wisdom of some of the most influential advertising creatives of our time -- people who've profoundly impacted our culture, yet are virtually unknown outside their industry. These artists and writers all brought a surprisingly rebellious spirit to their work in a business more often associated with mediocrity or manipulation: responsible for "Just Do It," "I Love NY, " "Where's the Beef?," "Got Milk," "Think Different," and brilliant campaigns for everything from cars to presidents. They managed to grab the attention of millions and truly move them...and if it moves you, then it's got to be art, baby...8:30pm

Where Goldie Hawn came from...

Before SATURDAY NIGHT LIVE, or THE DAILY SHOW, or THE COLBERT REPORT, there was ROWAN AND MARTIN'S LAUGH-IN, capturing the zeitgeist of the era with its anarchic energy and pop aesthetic. Combining the black-out comedy of the vaudeville tradition with a 1960s-style "happening," featuring psychedelic costumes, graphics, graffiti, and the ability to inject multiple funny phrases into popular language. THE BEST OF LAUGH-IN is a tribute to the show which not only transformed television but became an important training ground for an entire generation of young writers and comic talent...7pm

In the wake of the turbulent 1960s, Carole King, one of the great songwriters of the '60s, started playing piano in James Taylor's band, creating a bond that they still share today. It is through them and their unique voices that we chronicle this group of musicians, who played before, after, and alongside them. The story is told through archival footage, much of it never before seen, which is intercut with the vivid recollections and incisive reflections of a wide cast of characters. Along with King and Taylor, contributors include David Crosby, Roger McGuinn, Jackson Browne, Bonnie Raitt, Chris Darrow, Kris Kristofferson, J.D. Souther, and Elton John. As my good friend Wyatt says, "It's the soundtrack of our lives"...American Masters...8:30pm

"Love Me Tender" is Elvis as you've never seen him...

If it's Elvis, we must be in a membership drive...a major reason for Elvis Presley's massive, unprecedented appeal to women audiences of all ages was his love songs. Always a true romantic, Elvis recorded many, many love songs throughout his career, beginning with "I Want You I Need You I Love You" in 1956. Entire eras of his remarkable life and career can be evoked by the mere mention of the title of one of his many love songs. Mention "Love Me Tender" and a hundred images spring to mind. The same can be said for his many other songs of romance.
Elvis and his love songs had remained an unexplored area of Elvis' remarkable career. Now, "Love Me Tender - The Love Songs of Elvis" tells the warm story of the tender side of the King of Rock and Roll...7pm

Hey Mr. Tambourine man, play a song for me...
