A polyhedron resembling a sphere rotating around an axis.

A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object rotates always around an imaginary line called a rotation axis. If the axis is within the body, and passes through its center of mass the body is said to rotate upon itself, or spin. A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity.

Mathematics[link]

Rotation of a planar figure around a point

Rotational Orbit v Spin

Relations between rotation axis, plane of orbit and axial tilt (for Earth).

Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, respectively.)

All rigid body movements are rotations, translations, or combinations of the two.

A rotation is simply a progressive radial orientation to a common point. That common point lies within the axis of that motion. The axis is 90 degrees perpendicular to the plane of the motion. If the axis of the rotation lies external of the body in question then the body is said to orbit. There is no fundamental difference between a “rotation” and a “orbit” and or "spin". The key distinction is simply where the axis of the rotation lies, either within or without a body in question. This distinction can be demonstrated for both “rigid” and “non rigid” bodies.

If a rotation around a point or axis is followed by a second rotation around the same point/axis, a third rotation results. The reverse (inverse) of a rotation is also a rotation. Thus, the rotations around a point/axis form a group. However, a rotation around a point or axis and a rotation around a different point/axis may result in something other than a rotation, e.g. a translation.

Rotations around the x, y and z axes are called principal rotations. Rotation around any axis can be performed by taking a rotation around the x axis, followed by a rotation around the y axis, and followed by a rotation around the z axis. That is to say, any spatial rotation can be decomposed into a combination of principal rotations.

In flight dynamics, the principal rotations are known as yaw, pitch, and roll (known as Tait-Bryan angles). This terminology is also used in computer graphics.

[edit] Astronomy

In astronomy, rotation is a commonly observed phenomenon. Stars, planets and similar bodies all spin around on their axis. The rotation rate of planets in the solar system was first measured by tracking visual features. Stellar rotation is measured through Doppler shift or by tracking active surface features.

This rotation induces a centrifugal acceleration in the reference frame of the Earth which slightly counteracts the effect of gravity the closer one is to the equator. One effect is that an object weighs slightly less at the equator. Another is that the Earth is slightly deformed into an oblate spheroid.

Another consequence of the rotation of a planet is the phenomenon of precession. Like a gyroscope, the overall effect is a slight "wobble" in the movement of the axis of a planet. Currently the tilt of the Earth's axis to its orbital plane (obliquity of the ecliptic) is 23.44 degrees, but this angle changes slowly (over thousands of years). (See also Precession of the equinoxes and Pole star.)

Rotation and revolution[link]

While revolution is often used as a synonym for rotation, in many fields, particularly astronomy and related fields, revolution, often referred to as orbital revolution for clarity, is used when one body moves around another while rotation is used to mean the movement around an axis. Moons revolve around their planet, planets revolve about their star (such as the Earth around the Sun); and stars slowly revolve about their galaxial center. The motion of the components of galaxies is complex, but it usually includes a rotation component.

Retrograde rotation[link]

Most planets in our solar system, including Earth, spin in the same direction as they orbit the Sun. The exceptions are Venus and Uranus. Uranus rotates nearly on its side relative to its orbit. Current speculation is that Uranus started off with a typical prograde orientation and was knocked on its side by a large impact early in its history. Venus may be thought of as rotating slowly backwards (or being "upside down"). The dwarf planet Pluto (formerly considered a planet) is anomalous in this and other ways.

Physics[link]

The speed of rotation is given by the angular frequency (rad/s) or frequency (turns/s, turns/min), or period (seconds, days, etc.). The time-rate of change of angular frequency is angular acceleration (rad/s²), This change is caused by torque. The ratio of the two (how heavy is it to start, stop, or otherwise change rotation) is given by the moment of inertia.

The angular velocity vector also describes the direction of the axis of rotation. Similarly the torque is a vector.

According to the right-hand rule, the direction away from the observer is associated with clockwise rotation and the direction towards the observer with counterclockwise rotation, like a screw.

Aviation[link]

The principal axes of rotation in space

In flight dynamics, the principal rotations are known as pitch, roll and yaw. The term rotation is also used in aviation to refer to the upward pitch (nose moves up) of an aircraft, particularly when starting the climb after takeoff.

Amusement rides[link]

Many amusement rides provide rotation. A Ferris wheel has a horizontal central axis, and parallel axes for each gondola, where the rotation is opposite, by gravity or mechanically. As a result at any time the orientation of the gondola is upright (not rotated), just translated. The tip of the translation vector describes a circle. A carousel provides rotation about a vertical axis. Many rides provide a combination of rotations about several axes. In Chair-O-Planes the rotation about the vertical axis is provided mechanically, while the rotation about the horizontal axis is due to the centripetal force. In roller coaster inversions the rotation about the horizontal axis is one or more full cycles, where inertia keeps people in their seats.

Sports[link]

Rotation, usually called spin, plays a role in many sports. Topspin and backspin in tennis. English, follow and draw in billiards and pool. Curve balls in baseball and spin bowling in cricket. Table tennis paddles are specialized to allow players to spin the ball as they hit.

Herbert "Herb" Alpert (born March 31, 1935) is an American musician most associated with the group variously known as Herb Alpert & the Tijuana Brass, Herb Alpert's Tijuana Brass, or TJB. He is also a recording industry executive — he is the "A" of A&M Records (a recording label he and business partner Jerry Moss founded and eventually sold to Polygram). The multi-talented Alpert has also created abstract expressionist paintings and sculpture over two decades, which are on occasion publicly exhibited; and he and his wife are substantial US philanthropists through the operation of the Herb Alpert Foundation.

Alpert's musical accomplishments include five number one hits, 28 albums on the Billboard charts, eight Grammy Awards, fourteen Platinum albums and fifteen Gold albums.^[1] As of 1996, Alpert had sold 72 million albums worldwide.^[2][3][4] Alpert is the only recording artist to hit #1 on the U.S. Billboard Hot 100 pop chart as both an instrumentalist ("Rise", 1979) and vocalist (" This Guy's in Love With You", 1968).

Early life and career[link]

Alpert was born in Los Angeles, California,^[5] into a Jewish family of Russian and Romanian origins.^[4][6] His father Louis was from Radomyshl (present-day Ukraine) and although a tailor by trade, was also a talented mandolin player. His mother, Tillie, had her roots in Romania on her father's side; she herself taught violin at a young age. His older brother David was a talented young drummer.^[7] Alpert himself began trumpet lessons at the age of eight and played at dances as a teenager. Acquiring an early wire recorder in high school, he experimented on this crude equipment. After graduating from Fairfax High School in 1952, he joined the U.S. Army and frequently performed at military ceremonies. After his service in the Army, Alpert tried his hand at acting, but eventually settled on pursuing a career in music. While attending the University of Southern California in the 1950s, he was a member of the USC Trojan Marching Band for two years. In 1956, he appeared in the uncredited role "Drummer on Mt. Sinai" in the film "Ten Commandments".^[8] In 1962, he had an uncredited part in a scene in "Mr. Hobbs Takes a Vacation" where he played (and performed a solo) in a dance band.

In 1957, Alpert teamed up with Rob Weerts, another burgeoning lyricist, as a songwriter for Keen Records. A number of songs written or co-written by Alpert during the following two years became top twenty hits, including "Baby Talk" by Jan and Dean, "Wonderful World" by Sam Cooke, and "Alley-Oop" by The Hollywood Argyles and by Dante and The Evergreens.^[2] In 1960, Alpert began his recording career as a vocalist at RCA Records under the name of Dore Alpert.^[4]

"Tell It to the Birds" was recorded as the first release on the Alpert & Moss label Carnival Records. When Alpert and Moss found that there was prior usage of the Carnival name, their label became A&M Records.

The Tijuana Brass years[link]

Alpert set up a small recording studio in his garage and had been overdubbing a tune called "Twinkle Star", written by Sol Lake, who would eventually write many of the Brass's original tunes. During a visit to Tijuana, Mexico, Alpert happened to hear a mariachi band while attending a bullfight. Following the experience, Alpert recalled that he was inspired to find a way to express musically what he felt while watching the wild responses of the crowd, and hearing the brass musicians introducing each new event with rousing fanfare.^[9] Alpert adapted the trumpet style to the tune, mixed in crowd cheers and other noises for ambience, and renamed the song "The Lonely Bull".^[10] He personally funded the production of the record as a single, and it spread through radio DJs until it caught on and became a Top Ten hit in 1962. He followed up quickly with his debut album, The Lonely Bull by "Herb Alpert & the Tijuana Brass". Originally the Tijuana Brass was just Alpert overdubbing his own trumpet, slightly out of sync. The title cut reached #6 on the Billboard Pop Singles Chart. This was A&M's first album (the original number was 101), although it was recorded at Conway Records.

By the end of 1964, because of a growing demand for live appearances by the Tijuana Brass, Alpert auditioned and hired a team of crack session men. No one in Alpert's band was actually Hispanic. Alpert used to tell his audiences that his group consisted of "Four lasagnas, two bagels, and an American cheese": John Pisano (electric guitar); Lou Pagani (piano); Nick Ceroli (drums); Pat Senatore (bass guitar); Tonni Kalash (trumpet); Herb Alpert (trumpet and vocal); and Bob Edmondson (trombone). The band debuted in 1965 and became one of the highest-paid acts then performing, having put together a complete revue that included choreographed moves and comic routines written by Bill ("Jose Jimenez") Dana.

The Tijuana Brass's success helped spawn other Latin acts, notably Julius Wechter (long-time friend of Alpert's and the marimba player for the Brass) and the Baja Marimba Band, and the profits allowed A&M to begin building a repertoire of artists like Chris Montez and The Sandpipers. Wechter would contribute a number of the Brass' original songs, usually at least one per album, along with those of other Alpert friends, Sol Lake and Ervan "Bud" Coleman.

An album or two would be released each year throughout the 1960s. Alpert's band was featured in several TV specials, each one usually centered on visual interpretations of the songs from their latest album - essentially an early type of music videos later made famous by MTV. The first Herb Alpert and the Tijuana Brass special, sponsored by the Singer Sewing Machine Company, aired on April 24, 1967 on CBS.

Alpert's style achieved enormous popularity with the national exposure The Clark Gum Company gave to one of his recordings in 1964, a Sol Lake number titled "The Mexican Shuffle" (which was retitled "The Teaberry Shuffle" for the television advertisements). In 1965, Alpert released two albums, Whipped Cream (and Other Delights) and Going Places. Whipped Cream sold over 6 million copies in the United States. The album cover featured model Dolores Erickson wearing only what appeared to be whipped cream. In reality, Erickson was wearing a white blanket over which were scattered artfully-placed daubs of shaving cream—real whipped cream would have melted under the heat of the studio lights (although the cream on her head was real). In concerts, when about to play the song, Alpert would tell the audience, "Sorry, we can't play the cover for you." The art was parodied by several groups including one-time A&M band Soul Asylum and by comedian Pat Cooper for his album Spaghetti Sauce and Other Delights. The singles included the title cut, "Lollipops and Roses", and "A Taste of Honey." The latter won a Grammy Award for Record of the Year. Going Places produced four more singles: "Tijuana Taxi", "Spanish Flea", "Third Man Theme", and "Zorba the Greek". "Tijuana Taxi" and "Spanish Flea" would be used in the 1966 Academy Award-winning animated short A Herb Alpert and the Tijuana Brass Double Feature.

The Brass covered the Bert Kaempfert tune "Happy Trumpeter" retitling it "Magic Trumpet". Alpert's rendition contained a bar that coincided with a Schlitz beer tune, "When you're out of Schlitz, you're out of beer". ("The Maltese Melody" was another Alpert cover of a Kaempfert original). Another commercial use was a tune called "El Garbanzo", which was featured in Sunoco ads ("They're movin', they're movin', people in the know, they're movin' to Sunoco").

In 1967, the Tijuana Brass performed the title cut to the first movie version of Casino Royale.

Many of the tracks from Whipped Cream and Going Places received a great deal of airplay; they are frequently used as incidental music in The Dating Game on the Game Show Network, notably the tracks Whipped Cream, Spanish Flea and Lollipops and Roses. Despite the popularity of his singles, Alpert's albums outsold and outperformed them on the charts.

Alpert and the Tijuana Brass won six Grammy Awards. Fifteen of their albums won gold discs, and fourteen won platinum discs. In 1966 over 13 million Alpert recordings were sold, outselling the Beatles. That same year, the Guinness Book of World Records recognized that Alpert set a new record by placing five albums simultaneously in the top 20 on the Billboard Pop Album Chart, an accomplishment that has never been repeated. In April of that year, four of those albums were in the Top 10 simultaneously.

Alpert's only number one single during this period (and the first #1 hit for his A&M label) was a solo effort:^[11] "This Guy's in Love with You" (written by Burt Bacharach and Hal David),^[10] featuring a rare vocal. Alpert sang this to his first wife in a 1968 CBS Television special titled Beat of the Brass. The sequence was filmed on the beach in Malibu. The song was not intended to be released, but after it was used in the television special, allegedly thousands of telephone calls to CBS asking about it convinced Alpert to release it as a single, two days after the show aired.^[12] Although Alpert's vocal skills and range were limited, the song's unchallenging technical demands suited him.^[13] The single debuted in May 1968, topped the national chart for four weeks and ranked among the year's biggest hits. Initially regarded by the critical cognoscenti and 'hip' music-lovers of the day as strictly an easy-listening chart hit, Alpert's unusually expressive recording of "This Guy's in Love with You" now enjoys appeal well beyond the so-called mainstream. In 1996 at London's Royal Festival Hall, Noel Gallagher (of British rock band Oasis) performed the song with Burt Bacharach. Former Beatle George Harrison has stated that this was one of his favorite recordings.^{[citation needed]}

Life after the Brass[link]

Alpert disbanded the Tijuana Brass in 1969, then released another album by the group in 1971. In 1973, with some of the original Tijuana Brass members and some new members, he formed a group called Herb Alpert and the T.J.B. This new version of the Brass released two albums in 1974 and 1975 and toured. Alpert reconvened a third version of the Brass in 1984 after being invited to perform for the Olympic Games athletes at the Los Angeles Summer Games. The invitation led to the Bullish album and tour.

In the 1970s, 1980s, and 1990s, Alpert enjoyed a successful solo career. He had his biggest instrumental hit, "Rise" (from the album of the same name), which went number one in October 1979 and won a Grammy Award, and was later sampled in the number one 1997 rap song "Hypnotize" by the late rapper Notorious B.I.G. Both "Rise" and "Hypnotize" were written by Alpert's nephew, Randy Badazz Alpert and his friend Andy Armer. "Rise" made Alpert the only artist ever to hit #1 on the Billboard pop singles charts with both a vocal piece and an instrumental piece. Another Randy Badazz / Andy Armer song, "Rotation", hit #30 on the Billboard Pop Singles Chart. The song "Route 101" off the Fandango album peaked at number 37 in Billboard in August 1982. In 1987, Alpert branched out successfully to the R&B world with the hit album Keep Your Eye On Me, teaming up with producers Jimmy Jam and Terry Lewis on "Diamonds" and "Making Love In the Rain" featuring vocals by Janet Jackson and Lisa Keith.

Alpert performed "The Star-Spangled Banner" prior to Super Bowl XXII in San Diego, California in January 1988. It was the last non-vocal rendition of the national anthem at the Super Bowl to date.

From 1962 through 1992 Alpert signed artists to A&M Records and produced records. He discovered the West Coast band We Five. Among the notable artists he worked with personally are Chris Montez, The Carpenters, Sérgio Mendes and Brasil '66, Bill Medley, Lani Hall (Alpert's second and current wife), Liza Minnelli and Janet Jackson (featured vocalist on his 1987 hit single "Diamonds"). These working relationships allowed Alpert to place singles in the Top 10 in three different decades (1960s, 1970s, and 1980s).

Alpert and A&M Records partner Jerry Moss both agreed in 1987 to sell A&M to PolyGram Records for a reported $500 million. Both would continue to manage the label until 1993, when they left due to frustrations with PolyGram's constant pressure to force the label to fit into its corporate culture. Alpert and Moss then expanded their Almo Sounds music publishing company to produce records as well, primarily as a vehicle for Alpert's music. Almo Sounds imitates the former company culture embraced by Alpert and Moss when they first started A&M.

Awards and honors[link]

Alpert and Moss received a Grammy Trustees Award in 1997 for their lifetime achievements in the recording industry as executives and the Grammy Lifetime Achievement Award in 2007.

For his contribution to the recording industry, Alpert has a star on the Hollywood Walk of Fame at 6929 Hollywood Blvd. Moss also has a star on the Walk of Fame. Alpert and Moss were also inducted into the Rock and Roll Hall of Fame on March 13, 2006 as non-performer lifetime achievers for their work at A&M.

Alpert was referenced in the second show of the third season of Get Smart where one of the code signals between Maxwell Smart and his contact was "Herb Alpert takes trumpet lessons from Guy Lombardo." Also, a fifth-season episode parodied the entire group as Max and 99 sought to unmask "Herb Talbot and His Tijuana Tin" as KAOS spies.

On 17 September 2010 the TV documentary “Legends: Herb Alpert – Tijuana Brass and Other Delights” premiered on BBC 4.^[14]

Alpert has worked as a Broadway theatre producer, with his production of Tony Kushner's Angels in America winning a Tony Award.

In the 1980s Alpert created The Herb Alpert Foundation and the Alpert Awards in the Arts with The California Institute of the Arts (CalArts).^[15] The Foundation supports youth and arts education as well as environmental issues and helps fund the PBS series Bill Moyers on Faith and Reason and later Moyers & Company. Alpert and his wife donated $30 million to University of California, Los Angeles in 2007 to form and endow the UCLA Herb Alpert School of Music as part of the restructured UCLA School of the Arts and Architecture. He gave $24 million, which included $15 million from April 2008, to CalArts for its music curricula, and provided funding for the culture jamming activists The Yes Men.^[16]

He is actively overseeing the reissue of his music library. In 2000, Alpert acquired the rights to his music from Universal Music (current owners of A&M Records) in a legal settlement and began remastering his albums for compact disc reissue. In 2005, Shout! Factory began distributing digitally remastered versions of Alpert's A&M output, including a new album, Lost Treasures, consisting of unreleased material from Alpert's Tijuana Brass years. In the spring of 2006, a remixed version of the Whipped Cream album, entitled Whipped Cream and Other Delights: Re-Whipped was released and climbed to #5 on the Billboard Contemporary Jazz chart. Alpert's 80's catalog, which includes his two most successful solo albums, 1982's Fandango and 1987's Keep Your Eye on Me, are still unavailable on CD. He continues to be a guest artist for artists including Gato Barbieri, Rita Coolidge, Jim Brickman, Brian Culbertson, and David Lanz. Apart from the reissues, the Christmas Album continues to be available every year during the holiday season. On Sérgio Mendes' 2008 album Encanto, Alpert performed trumpet solos backing lead vocals by his wife on the song "Dreamer". It marked the first time Alpert, Mendes and Hall had all performed together on the same song. Most recently, Alpert and his wife (Lani Hall) signed with Concord Records and released a new (live) album in the summer of 2009, Anything Goes, which was Alpert's first release of new material since 1999's Herb Alpert and Colors.^[17] A new studio album by Alpert and Hall, I Feel You, was released in February 2011. Both albums feature tight jazz renditions of pop classics along with a handful of original compositions.

While Alpert continues to play trumpet, he also devotes time to his second career as an abstract expressionist painter and sculptor with group and solo exhibitions around the United States and Europe. The sculpture exhibition “Herb Alpert: Black Totems”, on display at ACE Gallery, Beverly Hills, February through September 2010, brought major media attention to his visual work.^[18]

Personal life[link]

Since 1974, Alpert has been married to recording artist Lani Hall. They have one daughter, actress Aria Alpert.

He was previously married to Sharon Mae Lubin frtom 1956 to 1971, but they divorced. They had two children together: daughter Eden and son Dore.^[4]

Susumu Hirasawa (平沢進, Hirasawa Susumu^?, born April 2, 1954 in Tokyo, Kantō region) is a Japanese electropop artist and composer.

In 1972, he enrolled at Tokyo Designer Gakuin College. From 1972 to 1978, he performed in his first band Mandrake, a progressive rock group influenced by King Crimson and Yes. In 1979 he formed a New Wave synth-rock & techno-pop band called P-Model, along with two former members of Mandrake. They released a string of albums through the 1980s, and in 1989, Hirasawa began releasing solo work, while also continuing to work with the reactivated P-Model beginning in 1992. The P-Model project continued until 1999; in 2004 Hirasawa started a new unit known as Kaku P-Model, which is effectively a solo continuation of P-Model.^[1]

Compositions and performances[link]

Hirasawa uses Amiga computers extensively in his work, using applications such as Scala, Bars and Pipes, and OctaMED in the production of his music. One of the factors that set him apart from other Japanese electronic artists is ever-changing production techniques. For 2001's Solar Ray album, his recording studio was powered completely by solar energy.^[1]

His subject matter can be equally unusual. A constant source of inspiration for his music has come from Thailand. In fact, the concept behind his 1995 album Sim City was drawn from his experiences travelling there, and more specifically, from Thai transsexuals. Guest Thai vocalists appear throughout that and proceeding albums, including 1996's Siren, which was also a concept album based on Thailand. As for his lyrical inspiration, Hirasawa references the philosophies of yin and yang, his travels and the principles of nature vs. machines.

Hirasawa occasionally stages interactive live performances. They merge computer graphics with his music to tell interactive stories, and involve heavy use of computers, particularly Amiga systems, motion capture cameras and video projectors. The flow of each live show is determined by audience participation; for example, Interactive Live Show 2000 was formatted as a maze, and the audience was allowed to choose which path to follow. Sometimes, audience participation plays a part in the performed music, as it did in Interactive Live Show 2000. He provided the phone numbers to four cellular phones during one song, and the audience was allowed to call the numbers to have him play the corresponding ringtone. This provided an improvised harmony between the background music and the ringing phones.^[2]

Hirasawa's live music is based on samples he activates with various hand-crafted sampler machines, pre-recorded tracks without vocals, and no regular backup performers. For the Solar Ray live tour, he used solar power and a power-generating wheel, inspired by bicycles, to power his electronic equipment. DVDs are available of his innovative award-winning live performances via his website (and ordering through Teslakite).

Activism[link]

Hirasawa spoke out against "the nations that are headed towards carnage while ignoring international law" and the actions of the Japanese government in aiding such actions. Specifically, he pointed to the American response after the September 11, 2001 attack, which he believes to involve excessive murder of innocent people. As a result of his convictions, Hirasawa has offered free downloads of his music, which he hopes will be used as tools of objection.^[3]
