157. Alicia Silverstone
Alicia Silverstone (born October 4, 1976) is an American actress, producer, author, and activist. Silverstone made her film debut in The Crush, earning the 1994 MTV Movie Award for Best Breakthrough Performance, and gained further prominence as a teen idol when she appeared in three music videos for the band Aerosmith. She starred in the 1995 hit Clueless (which earned her a multimillion-dollar deal with Columbia) and in the big-budget 1997 film Batman & Robin, in which she played Batgirl. She has continued to act in film and television and on stage. For her role in the short-lived drama comedy Miss Match, Silverstone received a Golden Globe nomination for Best Actress – Television Series Musical or Comedy. A vegan, Silverstone endorsed PETA activities and published a book titled The Kind Diet.
Silverstone was born in San Francisco, California, the daughter of Deirdre "Didi" (née Radford), a Scottish former Pan Am flight attendant, and Monty Silverstone, an English real estate agent. She grew up in Hillsborough, California. Her father was born to a Jewish family and her mother converted to Conservative Judaism before marriage; Silverstone had a Bat Mitzvah ceremony. Silverstone began modeling when she was six years old, and was subsequently cast in television commercials, the first being for Domino's Pizza. She attended Crocker Middle School and then San Mateo High School.
Silverstone has won several awards for her film performances. She received multiple MTV Movie Awards and a Young Artist Award for The Crush. For Clueless, she received multiple MTV Movie Awards and a Young Artist Award once again, plus awards from Blockbuster Entertainment Award, Kids' Choice Awards, National Board of Review, and an American Comedy Award.
Her first credited acting role was in The Wonder Years, starring Fred Savage, in the episode entitled "Road Test", as Savage's character's high school "dream girl". Silverstone then won a leading part in the 1993 film The Crush, playing a teenage girl who sets out to ruin an older man after he spurns her affections; she won two awards at the 1994 MTV Movie Awards for the role—Best Breakthrough Performance and Best Villain. Silverstone became legally emancipated at the age of 15 in order to work the hours required for the shooting schedule of the film. Silverstone made some television movies in her early career including Torch Song, Cool and the Crazy and Scattered Dreams. In addition, Silverstone was almost chosen to play the lead role of Angela Chase in the critically acclaimed cult television series My So-Called Life before production of the pilot episode began. The role eventually went to Claire Danes.
After seeing her in The Crush, Marty Callner decided Silverstone would be perfect for a role in a music video he was directing for the band Aerosmith, called "Cryin'"; she was subsequently cast in two more videos, "Amazing" and "Crazy." These were hugely successful for both the band and Silverstone, making her a household name (and also gaining her the nickname, "the Aerosmith chick"). After seeing Silverstone in the three videos, filmmaker Amy Heckerling decided to cast her in Clueless.
Clueless became a hit and critical darling during the summer of 1995. As a result, she signed a deal with Columbia-TriStar valued between $8 and $10 million. As part of the package, she got a three-year first look deal for her own production company, First Kiss Productions. Silverstone also won "Best Female Performance" and "Most Desirable Female" at the 1996 MTV Movie Awards for her performance in the film. In the same year Silverstone starred in the erotic thriller, The Babysitter, film adaptation of the novel by Dean Koontz, Hideaway, and the French drama about Americans, New World.
Silverstone's next role was as Batgirl in Batman & Robin, and while it was not a critical success, the film grossed $238,207,122 worldwide. Silverstone's turn as Batgirl was not well received, and won her a Razzie Award for Worst Supporting Actress. She also, however, won a Blimp Award at the Kid's Choice Awards for the role. Also released in 1997 was Excess Baggage, the first movie by Silverstone's production, Silverstone starred in the Saturn Award-nominated romance/comedy film Blast from the Past which also stars Brendan Fraser, Christopher Walken and Sissy Spacek.
In 2000, Silverstone appeared in Kenneth Branagh's film adaptation of the William Shakespeare's Love's Labour's Lost, in which she was required to sing and dance. In 2001, Silverstone provided the voice of Sharon Spitz, the lead character in the Canadian animated television Braceface. During this time, she also appeared in the films Global Heresy and Scorched. In 2002, she made her Broadway debut alongside Kathleen Turner and Jason Biggs in The Graduate. After removing herself from the public eye for a few years, she resurfaced in the short-lived 2003 NBC television series Miss Match, which was canceled after 11 episodes. Silverstone later acknowledged that she hates the trappings of fame, saying, "Fame is not anything I wish on anyone. You start acting because you love it. Then success arrives, and suddenly you're on show".
Alicia Silverstone in 2005
After the cancellation of Miss Match in 2003, Silverstone did a pilot with Fox called Queen B, in which she played a former high school prom queen named Beatrice (Bea) who has discovered that the real world is nothing like high school. It was not picked up for production. In 2005, she co-starred with Queen Latifah in Beauty Shop, a spinoff of the BarberShop films, as one of the stylists in the beauty shop. In the same year, she played a villainous reporter alongside Sarah Michelle Gellar and Freddie Prinze, Jr. in Scooby Doo 2: Monsters Unleashed, which did well financially, and appeared in the direct-to-video film Silence Becomes You.
In 2006, Silverstone starred in an ABC pilot called Pink Collar, in which her character worked in a law firm. Like Queen B, this pilot was not picked up to series. That year, she also starred alongside Alex Pettyfer, Ewan McGregor and Mickey Rourke in the film Stormbreaker, and appeared in the Hallmark Hall of Fame made-for-TV movie Candles on Bay Street, based on the book by Cathie Pelletier. Silverstone continued her theatre work, next appearing in David Mamet's Boston Marriage and Speed-the-Plow. In 2008, she filmed another ABC pilot alongside Megan Mullally called Bad Mother's Handbook and made a cameo appearance in the comedy film Tropic Thunder.
In early 2009, Silverstone starred in the world premiere of Donald Margulies's Time Stands Still at the Geffen Playhouse LA. The play focuses on a longtime couple and journalistic team who return to New York from an extended stint in the war-torn Middle East. She also starred in the music video for Rob Thomas's 2009 single "Her Diamonds".
Silverstone filmed a small segment in Elektra Luxx, a sequel to Women In Trouble. Director Sebastian Gutierrez cut her segment but will possibly use it for a third installment, tentatively titled Women In Ecstasy.
In 2010, she reprised her role in Time Stands Still alongside Laura Linney in the New York production of the play on Broadway, which premiered on January 28, 2010, directed by Daniel Sullivan, who described Silverstone as "a breath of fresh air." The play received good reviews with The New York Times praising Silverstone, saying she "brings warmth, actorly intelligence and delicate humour."
Silverstone next starred in the teen romance The Art of Getting By, which premiered at the 2011 Sundance Film Festival. and appeared in four episodes of Suburgatory, reuniting with her Clueless castmate Jeremy Sisto.
Her next role was in Butter as the adoptive mother of a 12-year-old African American girl who enters a local butter sculpture competition in a small Iowa town. Rob Corddry, who plays her husband, invited her to appear in an episode of his show Childrens Hospital. She also reunited with Clueless director Amy Heckerling in Vamps, playing one of two vampires who fall in love and face a choice that could jeopardise their immortality. She was offered the role after Heckerling came to see her in Time Stands Still.
Silverstone later returned to Broadway in the 2012 New York production of The Performers and starred in Angels in Stardust. In 2013, she shot TV pilot HR, which was not picked up. In 2015 she starred in the New York production of Of Good Stock.
She is set to appear in five upcoming movies: Who Gets the Dog? Catfight, King Cobra and Tribes Of Palos Verdes. In 2011 she starred in the film adaptation of Marie Phillips's novel Gods Behaving Badly, however as of 2016, it remains unreleased.
Silverstone has two older siblings, a half-sister from her father's previous marriage named Kezi Silverstone and a brother named David Silverstone. She married her longtime boyfriend, rock musician Christopher Jarecki, in a beachfront ceremony at Lake Tahoe on June 11, 2005. After meeting outside a movie theater in 1997, the couple dated for eight years prior to their marriage. They got engaged about a year before their marriage, and Jarecki presented Silverstone with an engagement ring that had belonged to his grandmother. They live in an eco-friendly Los Angeles house, complete with solar panels and an organic vegetable garden. Silverstone bought the house, shared with a "menagerie of rescued dogs", in 1996.
In 2009, Silverstone released The Kind Diet, a guide to vegan nutrition, and launched its associated website The Kind Life. The Kind Diet has topped the Hardcover Advice & Misc. category of The New York Times Best Seller list. In 2014, her follow up book The Kind Mama was published. She plans to write a third, The Kind Diet Cookbook.
Silverstone is noted for being an animal rights and environmental activist. She became a vegan in 1998 after attending an animal rights meeting, saying "I realized that I was the problem … I was an animal lover who was eating animals." She has stated she struggled with childhood vegetarianism, stating "at eight years old it's hard to stick to your guns – and so through the years I was always starting and stopping trying to be a vegetarian."

#6153. Name the American physicist who received the 1969 Nobel Prize in physics for his work on the theory of elementary particles (born September 15, 1929). He introduced, independently of George Zweig, the quark—constituents of all hadrons—having first identified the SU(3) flavor symmetry of hadrons. This symmetry is now understood to underlie the light quarks, extending isospin to include strangeness, a quantum number which he also discovered.
#6154. The smallpox vaccine was discovered in 1796 by the British physician Edward Jenner, although at least six people had used the same principles years earlier. Louis Pasteur furthered the concept through his work in microbiology. The immunization was called vaccination because it was derived from a virus affecting cows. Name the term 'cow' in Latin.
156. Arthur Holly Compton
Arthur Holly Compton, (born Sept. 10, 1892, Wooster, Ohio, U.S.—died March 15, 1962, Berkeley, Calif.) American physicist and joint winner, with C.T.R. Wilson of England, of the Nobel Prize for Physics in 1927 for his discovery and explanation of the change in the wavelength of X rays when they collide with electrons in metals. This so-called Compton effect is caused by the transfer of energy from a photon to an electron. Its discovery in 1922 confirmed the dual nature of electromagnetic radiation as both a wave and a particle.
Compton, a younger brother of the physicist Karl T. Compton, received his doctorate from Princeton University in 1916 and became head of the department of physics at Washington University, St. Louis, in 1920. Compton’s Nobel Prize–winning research focused on the strange phenomena that occur when beams of short-wavelength X rays are aimed at elements of low atomic weight. He discovered that some of the X rays scattered by the elements are of longer wavelength than they were before being scattered. This result is contrary to the laws of classical physics, which could not explain why the scattering of a wave should increase its wavelength. Compton initially theorized that the size and shape of electrons in the target atoms could account for the change in the X rays’ wavelength. In 1922, however, he concluded that Einstein’s quantum theory, which argued that light consists of particles rather than waves, offered a better explanation of the effect. In his new model, Compton interpreted X rays as consisting of particles, or “photons,” as he called them. He argued that an X-ray photon can collide with an electron of a carbon atom; when this happens, the photon transfers some of its energy to the electron and then continues on with diminished energy and a longer wavelength than it had before. Compton’s interpretation provided the first widely accepted experimental evidence that electromagnetic radiation can exhibit both particle and wave behaviour, and thus helped to establish the legitimacy of the still-radical quantum theory.
From 1923 to 1945 Compton was a professor of physics at the University of Chicago. In 1941 he was chairman of the committee of the National Academy of Sciences that studied the military potential of atomic energy. In this capacity he was instrumental, with the physicist Ernest O. Lawrence, in initiating the Manhattan Project, which created the first atomic bomb. From 1942 to 1945 he was director of the Metallurgical Laboratory at the University of Chicago, which developed the first self-sustaining atomic chain reaction and paved the way for controlled release of nuclear energy. He became chancellor of Washington University in 1945 and was professor of natural history there from 1953 until 1961.
The Answer #6147 is correct. Good work, bobbym!
(Thanks for the interesting information.)
#6149. Name the international treaty that was designed to reduce the movements of hazardous waste between nations, and specifically to prevent transfer of hazardous waste from developed to less developed countries (LDCs). It does not, however, address the movement of radioactive waste. The Convention is also intended to minimize the amount and toxicity of wastes generated, to ensure their environmentally sound management as closely as possible to the source of generation, and to assist LDCs in environmentally sound management of the hazardous and other wastes they generate.
#6150. Name the agreements made in 1929 between the Kingdom of Italy and the Holy See, settling the "Roman Question". (they were signed on February 11, 1929.)
