A wall thermometer

Celsius, formerly known as centigrade,^[1] is a scale and unit of measurement for temperature. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale. The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. The unit was known until 1948 as "centigrade" from the Latin centum translated as 100 and gradus translated as "steps".

From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere with mercury being the working material.^{[citation needed]} Although these defining correlations are commonly taught in schools today, by international agreement the unit "degree Celsius" and the Celsius scale are currently defined by two different temperatures: absolute zero, and the triple point of VSMOW (specially-purified water). This definition also precisely relates the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible at which matter reaches minimum entropy, is defined as being precisely 0 K and −273.15 °C. The temperature of the triple point of water is defined as precisely 273.16 K and 0.01 °C.^[2]

This definition fixes the magnitude of both the degree Celsius and the kelvin as precisely 1 part in 273.16 (approximately 0.00366) of the difference between absolute zero and the triple point of water. Thus, it sets the magnitude of one degree Celsius and that of one kelvin as exactly the same. Additionally, it establishes the difference between the two scales' null points as being precisely 273.15 degrees Celsius (−273.15 °C = 0 K and 0 °C = 273.15 K).^[3]

History[link]

An illustration of Anders Celsius's original thermometer. Note the reversed scale, where 0 is the boiling point of water and 100 is its freezing point.

In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale which was the reverse of the scale now known by the name "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water. In his paper Observations of two persistent degrees on a thermometer, he recounted his experiments showing that the melting point of ice is essentially unaffected by pressure. He also determined with remarkable precision how the boiling point of water varied as a function of atmospheric pressure. He proposed that the zero point of his temperature scale, being the boiling point, would be calibrated at the mean barometric pressure at mean sea level. This pressure is known as one standard atmosphere. The BIPM's 10th General Conference on Weights and Measures (CGPM) later defined one standard atmosphere to equal precisely 1013250dynes per square centimeter (101.325 kPa).^[4]

In 1744, coincident with the death of Anders Celsius, the Swedish botanist Carolus Linnaeus (1707–1778) reversed^[5] Celsius's scale upon receipt of his first thermometer featuring a scale where zero represented the melting point of ice and 100 represented the boiling point. His custom-made "linnaeus-thermometer", for use in his greenhouses, was made by Daniel Ekström, Sweden's leading maker of scientific instruments at the time and whose workshop was located in the basement of the Stockholm observatory. As often happened in this age before modern communications, numerous physicists, scientists, and instrument makers are credited with having independently developed this same scale;^[6] among them were Pehr Elvius, the secretary of the Royal Swedish Academy of Sciences (which had an instrument workshop) and with whom Linnaeus had been corresponding; Christian of Lyons; Daniel Ekström, the instrument maker; and Mårten Strömer (1707–1770) who had studied astronomy under Anders Celsius.

The first known document^[7] reporting temperatures in this modern "forward" Celsius scale is the paper Hortus Upsaliensis dated 16 December 1745 that Linnaeus wrote to a student of his, Samuel Nauclér. In it, Linnaeus recounted the temperatures inside the orangery at the Botanical Garden of Uppsala University:

"... since the caldarium (the hot part of the greenhouse) by the angle of the windows, merely from the rays of the sun, obtains such heat that the thermometer often reaches 30 degrees, although the keen gardener usually takes care not to let it rise to more than 20 to 25 degrees, and in winter not under 15 degrees ..."

Centigrade and Celsius[link]

Since the 19th century, the scientific and thermometry communities worldwide referred to this scale as the centigrade scale. Temperatures on the centigrade scale were often reported simply as degrees or, when greater specificity was desired, as degrees centigrade. The symbol for temperature values on this scale is °C.

Because the term centigrade was also the Spanish and French language name for a unit of angular measurement (1/10,000 of a right angle) and had a similar connotation in other languages, the term centesimal degree was used when very precise, unambiguous language was required by international standards bodies such as the BIPM. The 9th CGPM and the CIPM (Comité international des poids et mesures) formally adopted "degree Celsius" (symbol: °C) in 1948.^[8][9]

For scientific use, "Celsius" is the term usually used with "centigrade" otherwise continuing to be in common use.^[10]

Common temperatures[link]

Some key temperatures relating the Celsius scale to other temperature scales are shown in the table below.

Name and symbol typesetting[link]

The "degree Celsius" has been the only SI unit whose full unit name contains an uppercase letter since the SI base unit for temperature, the kelvin, became the proper name in 1967 replacing the term degree Kelvin. The plural form is degrees Celsius.^[16]

The general rule of the International Bureau of Weights and Measures (BIPM) is that the numerical value always precedes the unit, and a space is always used to separate the unit from the number, e.g., "23 °C" (not "23°C" or "23° C"). Thus the value of the quantity is the product of the number and the unit, the space being regarded as a multiplication sign (just as a space between units implies multiplication). The only exceptions to this rule are for the unit symbols for degree, minute, and second for plane angle (°, ′, and ″, respectively), for which no space is left between the numerical value and the unit symbol.^[17] Other languages, and various publishing houses, may follow different typographical rules.

Unicode character[link]

Unicode provides a compatibility character for the degree Celsius at U+2103 (decimal 8451), for compatibility with CJK encodings that provide such a character (as such, in most fonts the width is the same as for fullwidth characters). Its appearance is similar to the one synthesized by individually typing its two components (°) and (C). Shown below is the degree Celsius character followed immediately by the two-component version:

℃ °C

When viewed on computers that properly support Unicode, the above line may be similar to the image in the line below (enlarged for clarity):

The canonical decomposition is simply an ordinary degree sign and "C", so some browsers may simply display "°C" in its place due to Unicode normalization.

Temperatures and intervals[link]

The degree Celsius is a special name for the kelvin for use in expressing Celsius temperatures.^[18] The degree Celsius is also subject to the same rules as the kelvin with regard to the use of its unit name and symbol. Thus, besides expressing specific temperatures along its scale (e.g. "Gallium melts at 29.7646 °C" and "The temperature outside is 23 degrees Celsius"), the degree Celsius is also suitable for expressing temperature intervals: differences between temperatures or their uncertainties (e.g. "The output of the heat exchanger is hotter by 40 degrees Celsius", and "Our standard uncertainty is ±3 °C").^[19] Because of this dual usage, one must not rely upon the unit name or its symbol to denote that a quantity is a temperature interval; it must be unambiguous through context or explicit statement that the quantity is an interval.^[20] This is sometimes solved by using the symbol °C (pronounced "degrees Celsius") for a temperature, and C° (pronounced "Celsius degrees") for a temperature interval, although this usage is non-standard.^[21]

What is often confusing about the Celsius measurement is that it follows an interval system but not a ratio system; that it follows a relative scale not an absolute scale. This is put simply by illustrating that while 10 °C and 20 °C have the same interval difference as 20 °C and 30 °C the temperature 20 °C is not twice the air heat energy as 10 °C. As this example shows, degrees Celsius is a useful interval measurement but does not possess the characteristics of ratio measures like weight or distance.^[22]

Coexistence of Kelvin and Celsius scales[link]

In science and in engineering, the Celsius scale and the Kelvin scale are often used in combination in close contexts, e.g., "...a measured value was 0.01023 °C with an uncertainty of 70 µK..."). This practice is permissible because the magnitude of the degree Celsius is equal to that of the kelvin.

Notwithstanding the official endorsement provided by decision #3 of Resolution 3 of the 13th CGPM, which stated "a temperature interval may also be expressed in degrees Celsius", the practice of simultaneously using both °C and K remains widespread throughout the scientific world as the use of SI prefixed forms of the degree Celsius (such as "µ°C" or "microdegrees Celsius") to express a temperature interval has not been well-adopted.

This practice should be avoided for literature directed to lower-level technical fields and in non-technical articles intended for the general public where both the kelvin and its symbol, K, are not well recognized and could be confusing.

Melting and boiling points of water[link]

One effect of defining the Celsius scale at the triple point of Vienna Standard Mean Ocean Water (VSMOW, 273.16 K and 0.01 °C), and at absolute zero (0 K and −273.15 °C), is that neither the melting nor boiling point of water under one standard atmosphere (101.325 kPa) remain defining points for the Celsius scale. In 1948 when the 9th General Conference on Weights and Measures (CGPM) in Resolution 3 first considered using the triple point of water as a defining point, the triple point was so close to being 0.01 °C greater than water's known melting point, it was simply defined as precisely 0.01 °C.^[23] However, current measurements show that the triple and melting points of VSMOW are actually very slightly (<0.001 °C) greater than 0.01 °C apart. Thus, the actual melting point of ice is very slightly (less than a thousandth of a degree) below 0 °C. Also, defining water's triple point at 273.16 K precisely defined the magnitude of each 1 °C increment in terms of the absolute thermodynamic temperature scale (referencing absolute zero). Now decoupled from the actual boiling point of water, the value "100 °C" is hotter than 0 °C—in absolute terms—by a factor of precisely Failed to parse (Missing texvc executable; please see math/README to configure.): \textstyle\frac{373.15}{273.15}

(approximately 36.61% thermodynamically hotter). When adhering strictly to the two-point definition for calibration, the boiling point of VSMOW under one standard atmosphere of pressure is actually 373.1339 K (99.9839 °C). When calibrated to ITS-90 (a calibration standard comprising many definition points and commonly used for high-precision instrumentation), the boiling point of VSMOW is slightly less, about 99.974 °C.[24]

This boiling-point difference of 16.1 millikelvin between the Celsius scale's original definition and the current one (based on absolute zero and the triple point) has little practical meaning in common daily applications because water's boiling point is very sensitive to variations in barometric pressure. For example, an altitude change of only 28 cm (11 in) causes the boiling point to change by one millikelvin.

Worldwide adoption[link]

Throughout the world, except in the United States, Belize^[25] and a few other countries,^[specify] the Celsius temperature scale is used for practically all purposes. The only exceptions are some specialist fields (e.g., low-temperature physics, astrophysics, light temperature in photography) where the closely related Kelvin scale dominates instead.

Even in the U.S., almost the entire scientific field and many engineering fields use the Celsius scale, and the metric system in general. However, most Americans remain more accustomed to the Fahrenheit scale, which is the scale that U.S. broadcasters use in weather forecasting. It is also commonly used in the U.S. for measurement of body temperature, and household use such as cooking, and is the scale commonly seen on ovens and in recipes. In Canada, kitchen devices, literature, and packaging include both Fahrenheit and Celsius quotations.

The United Kingdom has gradually increased use of the Celsius scale since the 1970s and is now the predominant temperature scale used, but it is widely called centigrade. Most broadcasters and publications still quote Fahrenheit air temperatures alongside Celsius in weather forecasts, and air-temperature thermometers sold show both scales.

Holly Brook Hafermann (born February 23, 1986) better known by her stage name Skylar Grey, is an five-time Grammy-nominated American multi-instrumentalist, singer, songwriter, and record producer. Grey was signed to Machine Shop Recordings under the name Holly Brook. She released her debut album as Holly Brook, Like Blood Like Honey, in 2006. She co-wrote the three versions of "Love the Way You Lie" (for Eminem and Rihanna) with Alex da Kid, who signed her to his Wonderland Music label. She was featured as a guest vocalist on Fort Minor's "Where'd You Go" and "Be Somebody", Diddy-Dirty Money's "Coming Home", Dr. Dre's "I Need a Doctor", Lupe Fiasco's "Words I Never Said" and Kaskade's "Room for Happiness".

Life and career[link]

2001–2010: Early life and career beginnings[link]

Grey performed professionally as a child in a folk duo with her mother called Generations.^[3] Together, (with producer/engineer Randy Green) they independently produced three albums, Dream Maker, Lift Me, and Millennial Child/Waiting For You. Grey started her first band at the age of fifteen after 'sneaking' into bars, working with jazz musicians including Jeff Eckles, Tim Whalen and Leo Sidran in Madison, Wisconsin.

In 2003, Grey moved to Los Angeles and recorded a demo as Holly Brook, which would be her stage name for several years. This demo led to her being signed in the fall of 2004 by Linkin Park guitarist Brad Delson to the band's vanity label, Machine Shop Recordings; she was 18 years old. Her voice is featured on the Fort Minor songs "Where'd You Go" and "Be Somebody". Working with producer Jonathan Ingoldsby, Brook released her debut album, Like Blood Like Honey, on June 6, 2006. She landed opening spots for tours with Jamie Cullum, KD Lang, Daniel Powter, Teddy Geiger and Duncan Sheik.

In 2010, Brook lent both her song "It's Raining Again" and her image to a promotional campaign for Ciao Water.^[4] Prior to this, she has appeared on albums by other artists, including Brie Larson's Finally Out of P.E. and Fort Minor's The Rising Tied. Brook has toured with as part of Duncan Sheik's band, and appears heavily on his 2009 album Whisper House. At the beginning in 2010 she also performed in the theatrical version of "Whisper House," playing one of the two lead ghost vocalists along with David Poe.^[5] Also in 2010, she self-released the seven-song O’Dark:Thirty EP, produced by Duncan Sheik and Jon Ingoldsby.^[6] In 2009, Brook appeared as a backing vocalist on Eurovision contestant, Yohanna's debut album, Butterflies and Elvis.

[edit] 2011: Invinsible

Brook later changed her name to Skylar Grey. She explained that “it represents the unknowns in life. People seem to be afraid of the unknowns, but I’m the complete opposite. I dive into the unknown because I feel like that’s where all your possibilities come from.”^[7] She explained to Beatweek that she chose "grey" with an e rather than an a because “I like to do things the original way" and because "it’s more masculine. I’m not a very feminine person."^[8]

She was still living in Oregon and had no recognition as Skylar Grey. Grey went to New York to meet her publisher, Jennifer Blakeman, who played Grey the song "Airplanes" by B.O.B and Hayley Williams and produced by Alex da Kid; Grey liked what she heard so Blakeman introduced her and Alex da Kid via e-mail. Alex da Kid sent Grey a few tracks he had been working on and the first song she wrote was "Love The Way You Lie".

Alex da Kid signed her to a production deal on his KIDinaKORNER imprint.^[9] She wrote the hook to all three versions of "Love the Way You Lie" by rapper Eminem and Rihanna as well as all of the lyrics and melody to versions II and III of the song. She can be heard performing the demo for all versions of the song. Grey earned a Grammy nomination for Song of the Year for her writing contributions to "Love the Way You Lie".^[10] She also co-wrote Diddy-Dirty Money's "Coming Home",^[11] along with "Castle Walls" by T.I. and Christina Aguilera.^[12] On March 10, 2011, Diddy-Dirty Money performed the single "Coming Home" with Grey and Dirty Money vocalists, Dawn Richard and Kalenna Harper, live on American Idol.^[13]

She is also a writer and featured guest on "I Need a Doctor".^[14] Grey is also featured on Lupe Fiasco's third studio album Lasers, on the second single, "Words I Never Said" and was also featured in the live performance of the song, with Lupe, on The Colbert Report on May 9, 2011. Grey made her live performance debut under her new alias during the 53rd Grammy Awards, performing "I Need a Doctor" alongside Eminem and Dr. Dre. She is currently working on her solo studio album Invinsible with Alex Da Kid. She has signed to Interscope Records through Da Kid's KIDinaKORNER,^[15] and her first promotional buzz single "Dance Without You"^[16] was released on June 6, 2011, with the official music video being released on July 5.^[17] The first official single "Invisible" was released to radio on June 16. On July 9, 2011, Grey performed live at the World Peace Event in Washington, DC, appearing along with the 14th Dalai Lama.^[18][19] On 6 August, she performed at the 20th Lollapalooza festival as both a solo artist and with Eminem during the song "I Need A Doctor". The next day, while passing by the area where YouTube sensation Karmin was recording their cover of "I Need A Doctor," Grey joined the duo for an impromptu performance.^[20] She performed alongside rapper Eli Porter on the September 20, 2011 episode of Tosh.0.

Grey also featured on Kaskade's 2011 album Fire & Ice, writing and singing on two versions of the song "Room for Happiness", which became the album's third single.

It was also reported that Grey would be contributing to The Band Perry's sophomore album, which is set to be released in 2012.^[21][22]

On April 1, 2012 Grey performed the hit song Invinsible with Machine Gun Kelly at Wrestlemania XXVIII before John Cena's entrance at the main event against Dwayne "The Rock" Johnson.

Influences[link]

Grey has listed Garbage, Joni Mitchell, Marilyn Manson, Bob Dylan, Neil Young, Sarah McLachlan and Death Cab for Cutie as her influences.^[23][24]

Michael Carlyle Hall (born February 1, 1971) is an American actor whose television roles include David Fisher on the HBO drama series Six Feet Under and Dexter Morgan on the Showtime series Dexter. In 2009, Hall won a Golden Globe award and a Screen Actors Guild Award for his role in Dexter.^[1]

Early life[link]

Hall was born in Raleigh, North Carolina. His mother, Janice Styons Hall, is a high school guidance counselor in Wake Forest, and his father, William Carlyle Hall, worked for IBM.^[2] Hall grew up an only child, a sister having died in infancy before his birth. He has said of growing up a single child, that "There was a very one-on-one, immediate family relationship, my mom and I". His father died of prostate cancer in 1982, when Hall was 11 years old.^[3] In a 2004 interview, he stated

Hall attended Ravenscroft School in Raleigh, graduating in 1989.^[5] He graduated from Earlham College in 1993 and had planned to become a lawyer. He later attended New York University's Graduate Acting Program at the Tisch School of the Arts, graduating in 1996.^[6]

Career[link]

Early on in life Hall discovered acting, performing in “What Love Is” while in the second grade at Ravenscroft School. When he was in fifth grade, he began singing in a boy's choir, then graduated to musicals in high school, performing in standards such as The Sound of Music, Oklahoma! and Fiddler on the Roof.

Hall's acting career began in the theater. Off-Broadway, he appeared in Macbeth and Cymbeline at the New York Shakespeare Festival, and in Timon of Athens and Henry V at The Public Theater, The English Teachers at the Manhattan Class Company (MCC), and the controversial play Corpus Christi at the Manhattan Theatre Club. He also performed in the workshop production of what was then known as Sondheim's Wise Guys, later versions of which were titled Bounce and, finally, Road Show. He sang the role of Paris Singer; this character's songs and function in the play were transferred to the character Hollis Bessamer in the final version of the play. In Los Angeles, he appeared in Skylight at the Mark Taper Forum.

Stage[link]

Hall performed from August 4, 1998 to August 30, 1998, on the play called "Cymbeline" as Posthumus Leonatus.

In 1999, director Sam Mendes cast Hall as the flamboyant Emcee in the revival of Cabaret, his first Broadway role.

In 2003, Hall toured as Billy Flynn in the musical Chicago. In 2005 he returned to Off-Broadway theater in the premiere of Noah Haidle's Mr. Marmalade, playing the title character, an emotionally disturbed little girl's imaginary friend.

From July 21 to August 1, 2004, Hall performed at Michael John LaChiusa's musical called "R shomon", at the Williamstown Theatre Festival's Nikos Stage.

[edit] Six Feet Under

Mendes suggested Hall for the role of closeted David Fisher when Alan Ball began casting the TV drama Six Feet Under. "Everything I opened up for Cabaret," Hall reported in a 2004 interview, "I slammed shut for David."^[4]

Hall's work in the first season of Six Feet Under was recognized by an Emmy nomination for Outstanding Lead Actor in a Drama Series^[7] and for an AFI Award nomination for Actor of the Year in 2002 for his role as David Fisher. In addition, he shared in the Screen Actors Guild nominations for Outstanding Performance by an Ensemble in a Drama Series all five years that the show was in production, winning the award in 2003 and 2004.^[8]

[edit] Dexter

Hall at the 2009 Comic-Con

Hall is currently starring in and co-producing the Showtime television series Dexter, in which he plays the titular character, a blood-spatter analyst for the Miami Metro Police Department who moonlights as a vigilante serial killer. The series also casts Hall's ex-wife, Jennifer Carpenter as his foster sister, Debra Morgan. The series premiered on October 1, 2006 and its sixth season began on October 2, 2011. For his work on Dexter, Hall has been nominated for three more Emmy Awards for Outstanding Lead Actor in a Drama Series, in 2008, 2009 and 2010. The show itself was also nominated for a 2008, 2009 and 2010 Emmy in the Drama Series category.^[9] He won the 2007 Television Critics Association Award for Individual Achievement in Drama.^[10] Hall was nominated for the Golden Globe Award for Best Performance by an Actor in a TV Drama in 2007, and again in 2008 ^[11] finally winning the award at the 67th Golden Globe Awards in 2010.^[12] Also in 2010, he won a Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Drama Series. On December 4, 2010, Showtime announced that Dexter would be renewed for a sixth season and stated that a seventh season was possible.^[13][14] Season 6 premiered on October 2, 2011. Michael C. Hall was nominated for Best Leading Actor in a Drama series at the 2011 Emmy Awards, but did not win the category. Hall was negotiating his contract along with Showtime to raise his salary for the seventh season.^[15] On November 18, 2011, it was announced that Dexter had been renewed for both a seventh and eighth season.^[16]

Film[link]

Hall's film credits include the 2003 thriller Paycheck, the 2009 science fiction thriller Gamer, the 2011 comedy Peep World and 2011 The Trouble with Bliss.

Commercials[link]

In 2009, Hall began doing voice-overs for some Dodge commercials, including the Challenger, Charger, Durango, Grand Caravan, and Journey, as well as the Jeep Grand Cherokee.

Personal life[link]

On May 1, 2003, Hall married actress Amy Spanger; he played Billy Flynn opposite her Roxie Hart in the Broadway musical Chicago the summer after their wedding. The couple separated in 2005 and filed for divorce in 2006. On December 31, 2008, he eloped with Jennifer Carpenter, who plays the character of Dexter Morgan's adoptive sister, Debra Morgan, on Showtime's Dexter. They dated for a year prior to getting married.^[17][18] On December 18, 2010, Carpenter filed for divorce from Hall, citing irreconcilable differences. The filing also stated that the two had been separated since August 2010 and that she was seeking spousal support.^[19] Their divorce was finalized on 2 December 2011. Dexter and deb are now back together

Cancer[link]

On January 13, 2010, his agent and spokesman confirmed that he was undergoing treatment for a treatable form of Hodgkin's lymphoma.

Hall accepted his Golden Globe and Screen Actors Guild Award in 2010 while wearing a knitted cap over his bald head, having lost his hair due to chemotherapy.^[20] On April 25, 2010, Carpenter announced that Hall was fully cured^[21] and was set to get back to work for a new season of Dexter.^[22]

He is now cancer-free.

Charity[link]

He is currently the face of the Somalia Aid Society's Feed The People campaign. Recently, he has also worked with Kiehl's skin care line to do a limited edition line that benefits the Waterkeeper Alliance, an environmental nonprofit that works towards clean and safe water worldwide.^[23]
