# 2003 Red Bull Air Race World Series

The 2003 Red Bull Air Race World Series was the 1st Red Bull Air Race World Series season. It started on June 28, 2003 and ended on August 20.
In the 2003 season, there were two air race venues only, Zeltweg in Austria and Budapest in Hungary.
Six pilots competed in the first leg. Due to a timing dispute, no points were given. In the second and final round, only three pilots participated. Hungarian Péter Besenyei won the race in Budapest and so the 2003 championship with 6 points. Klaus Schrodt from Germany became second before the American pilot Kirby Chambliss.

# 2008 French Senate election

Indirect Senate elections were held for 114 of the 343 seats in the French Senate on 21 September 2008. With this election, the number of senators was increased from 331 to 343; Saint Barthélemy and Saint Martin elected two senators each for the first time. Furthermore, this election was the last to be held under the old system: prior to this election, senators were elected in three classes for nine-year terms. Under the new system instituted in 2011, senators are elected for six-year terms in two classes.

## New seats

Twelve new seats were filled in this election. They were divided in the following way: 1 new Senator each for the Ain, Alpes-Maritimes, Bouches-du-Rhône, Drôme, Eure-et-Loir, Haute-Garonne, Gironde, Hérault, and Guyane départements and one in French Polynesia.
The election marked the first time that French Polynesia had two seats in the Senate instead of just one. The President of French Polynesia Gaston Tong Sang and another member of his coalition, Béatrice Vernaudon, a former member of the French National Assembly who lost her seat in June 2007, contested the seats. Former French Polynesian President Gaston Flosse ran for his Tahoeraa Huiraatira Party and teamed up with Richard Tuheiava, a member of the pro-independence party Union for Democracy.

## System
### Electoral college

For the 114 seats up for election, the electoral college was composed of 50,720 elected officials (49,602 in metropolitan France). Of these, 48,453 were local councillors, 178 were MPs, 765 were regional councillors and 1,504 were general councillors.

### Election

* Departments with 1 to 3 senators: Two-round system, using the same system as legislative elections.
* Departments with 4 or more senators: Proportional representation, highest averages method, no Panachage or preferential voting.

# Experimental biology

Experimental biology is the set of approaches in the field of biology concerned with the conduction of experiments to investigate and understand biological phenomena. The term is opposed to theoretical biology which is concerned with the mathematical modelling and abstractions of the biological systems. Due to the complexity of the investigated systems, biology is primarily an experimental science. However, as a consequence of the modern increase in computational power, it is now becoming more feasible to find approximate solutions and validate mathematical models of complex living organisms.
The methods employed in experimental biology are numerous and of different nature including molecular, biochemical, biophysical, microscopical and microbiological. See Category:Laboratory techniques for a list of biological experimental techniques.

Black Box: The Complete Original Black Sabbath 1970–1978 is a collection of the first eight albums by the heavy metal band and a DVD of 4 videos. The set contains the albums recorded with original singer Ozzy Osbourne, who was fired in 1979 after completion of the band's Never Say Die! tour. This marked the end of the group's original line-up that featured Osbourne, guitarist Tony Iommi, bassist Geezer Butler and drummer Bill Ward. All eight albums are digitally remastered and repackaged in mock vinyl LP packaging, including an 80-page booklet with liner notes written by Henry Rollins, Chris Welch, and Brian Ives. The discs included in the set are as follows:
* 1970 Black Sabbath
* 1970 Paranoid
* 1971 Master of Reality
* 1972 Vol. 4
* 1973 Sabbath Bloody Sabbath
* 1975 Sabotage
* 1976 Technical Ecstasy
* 1978 Never Say Die!
* 2004 Bonus DVD:
       Track list:
      * "Black Sabbath"
      * "Paranoid"
      * "Iron Man"
      * "Blue Suede Shoes"
They are represented as they appeared when first released, with the exception of the debut album, which has a revised track order as it includes both the song "Evil Woman" from the original European LP—deleted from North American editions because of copyright problems—and "Wicked World", which was substituted for it. The discs are kept in digipak cases, with all original LP artwork intact. The CDs themselves are entirely black, but retain the lettering used for each individual release, as opposed to a uniform stylized font.
True to its title, the nine discs are housed in a solid black case, complete with gothic imagery and lettering. Inside, there are two smaller boxes containing four CDs each. Also enclosed is a booklet, which contains the DVD in a sleeve attached to the inside back cover. The booklet traces the entire history of the band, with essays, interviews, timelines, and the lyrics to every song personally checked by Geezer Butler, the band's main lyricist.
Previously, a 1996 remastered box set had been issued by Castle Communications, which used unknown source tapes and did not involve any input from the band. For the Rhino set, all of the songs have been digitally remastered from the original Warner Bros. tape archives, as was the earlier Rhino compilation Symptom of the Universe.

# Bais Chana Women International

Bais Chana Women International is a Chabad non-profit organization that works to provide an environment for Jewish girls and women, ages 15 and up and from all backgrounds, to explore Jewish teachings and traditions.

## Overview

Bais Chana's founding was inspired and motivated by the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson's support of Jewish education for all women. In 1971, its first home was opened in the Twin Cities, Minnesota.
In 1991 the organization began diversifying its program to include shorter retreat segments in locations around the world. Women of all ages and little or no formal background in Jewish traditions have taken part in these educational retreats, which include classes, group study, private tutoring and mentoring.
The full class schedule explores life as a Jewish woman, comprising discussion and in-depth study of Hasidic texts, Torah, prayer, Bible commentary, Midrash, Maimonides, Kabbalah, Talmud and more; and incorporating hands-on projects such as challah baking. The rotating teaching staff features Bais Chana's co-founder, Rabbi Manis Friedman.
Under the direction of Mrs. Hinda Leah Sharfstein, Bais Chana is now headquartered in New York and has further expanded to include three annual sessions at an array of venues across the United States, including learning retreats for couples, the Snorkel and Study Program, and The Jewish Un-Camp.
* Throughout the year there are small-scale retreats around the United States such as the Thanksgiving Retreat that was held in Morristown, NJ for High School girls in 2007.
* The Snorkel and Study Program, which began in January 2006, is held annually in Key Largo, Florida, and attended by up to 90 female students from campuses around the world.
* The Un-Camp is geared towards teens, and participants discuss topics such as "prayer, science, mitzvahs, self-image, relationships, happiness, life and death, the Jewish belief in the Messiah, the soul," and more while participating in traditional summer camp activities.
Anthropologist Lynn Davidman performed fieldwork for her doctoral dissertation at Bais Chana. The results of her study have been published in her book Tradition in a Rootless World: Women Turn to Orthodox Judaism (UC Press, 1993). Davidman found that the majority of young women at Bais Chana were there to fill a void in their lives, and were hoping to find an Orthodox husband and begin a family, and that "strong boundaries" were established "between the [Chabad] religious group and the outside."
