[[File:Mathnet.jpg|thumb|right|Kate Monday (Beverly Leech) and George Frankly (Joe Howard)]]
'''''Mathnet''''' is a segment on the children's television show ''[[Square One Television]]'' that follows the adventures of pairs of police mathematicians. It is a [[pastiche]] of ''[[Dragnet (1951 TV series)|Dragnet]]''.

==Premise==
''Mathnet'' is a [[pastiche]] of ''[[Dragnet (1951 TV series)|Dragnet]]'', in which the main characters are [[mathematician]]s who use their [[mathematics|mathematical skills]] to solve various crimes and [[Mystery fiction|mysteries]] in the city, usually thefts, burglaries, frauds, and kidnappings. Each segment of the series aired on one episode of ''[[Square One Television|Square One]]'', a production of the [[Children's Television Workshop]] (CTW) aimed at teaching math skills to young viewers. Five segments made up an episode (one for each weekday), with suspense building at the end of each segment. Instead of guns, the detectives carry calculators.

==Characters==
* '''Kate Monday''' (Beverly Leech) – A pastiche of [[Jack Webb]]'s ''Dragnet'' character [[Joe Friday]], Kate usually remains stoic when on the job and tackles almost every situation with a calm and rational mind. She appears in the first three seasons.
* '''George Frankly''' (Joe Howard) – The partner of Kate Monday (and later Pat Tuesday), George takes his job seriously but is frequently prone to fits of comical mishaps and immature reactions. He appears in all five seasons. He has a wife named Martha whom he often mentions but who is never seen or heard.
* '''Pat Tuesday''' (Toni DiBuono) – George's second partner, appearing in Seasons 4 and 5 to replace Kate. Like Kate, Pat shares the deadpan mannerisms and no-nonsense attitude of Joe Friday.

===Los Angeles cast===
* '''Thad Green''' ([[James Earl Jones]]) – The chief of the Los Angeles Police Department. He briefly appears in Season 4.
* '''Debbie Williams''' (Mary Watson) – Technical analyst at the LAPD division where Kate and George works, she is frequently called upon to process data obtained during Mathnet investigations.

===New York City cast===
* '''Joe Greco''' (Emilio Del Pozo) – Captain of the New York City precinct, he is the man who George, Kate, and later Pat report to when they move to New York City starting in Season 3.
* '''Benny Pill''' (Bari K. Willerford) – An undercover [[New York City Police Department|NYPD]] officer, he is Mathnet's semi-regular backup support.

==Guest stars==

In addition, real-life [[Los Angeles Police Department|LAPD]] officers Sam Salazar and Steve Fellman appeared as themselves; head writers David D. Connell and Jim Thurman also appeared as various characters.

==Math and science==
Real principles of math and science and mathematical tools used by the detectives to solve crimes include:
* [[Alphanumerics]] ("The Case of the Unnatural")
* [[Fibonacci sequence]] and [[modular arithmetic]] (see also [[Pisano period]]) ("The Case of the Willing Parrot")
* [[Kinematics]] ("The Problem of the Missing Baseball")
* [[Chromatic scale]] ("The Problem of the Passing Parade")
* [[Displacement (fluid)|Displacement of fluids]] ("The Problem of the Trojan Hamburger")
* [[Hamiltonian path]] ("The Case of the Smart Dummy")
* [[Process of elimination]] ("The Case of the Great Car Robbery", "The View from the Rear Terrace")
* [[Pattern#Science and mathematics|Number patterns]] ("The Case of the Missing Air")
* [[Bar chart]]s and [[line chart]]s ("The Case of the Purloined Policies", "The Case of the Great Car Robbery")
* [[Triangulation]] ("The Case of the Map With a Gap")

==Development and production==
After a successful first season, production began on six new episodes for the second season. By the time production ended on the third season and its six episodes in 1989, Beverly Leech (Kate Monday) left, and was replaced by a new character named Pat Tuesday, played by Toni DiBuono. Production on the first six episodes with the new character commenced in 1990, and ended in 1991, in time for ''Square One TV's'' fourth season. Production on the final season and its five episodes began taping in 1991, and the last episode aired in 1992.

During production, the background music also changed. Originally, it had a synth score. Gradually, as the series progressed, it was replaced with an orchestral score.

The exterior shots of the Los Angeles police station were filmed at the former LAPD [[Highland Park Police Station]], which had closed in 1983.<ref>{{cite web|title=The Los Angeles Police Historical Society|url=http://www.lapdonline.org/history_of_the_lapd/content_basic_view/1121 |work=LAPD Online |access-date=6 April 2018}}</ref> It now houses the Los Angeles Police Museum and is located at 6045 York Boulevard.<ref>{{cite web|url=http://www.laphs.org |title=Los Angeles Police Museum |website=Los Angeles Police Museum}}</ref><ref>{{cite web|url=https://maps.google.com/maps?oe=&ie=UTF-8&q=los+angeles+police+society&fb=1&gl=us&hq=police+society&hnear=0x80c2c75ddc27da13:0xe22fdf6f254608f4,Los+Angeles,+CA&cid=0,0,16157549188208978139&ei=-2_lUefTMqjzygGik4CQDA&ved=0CDMQrwswAA|title=Los Angeles Police Museum |website=Google Maps}}</ref>

The exterior shots of the New York City police station for seasons 3 and 4 were filmed at the [[Alexander Hamilton U.S. Custom House]] in [[Lower Manhattan]]. It now houses the [[George Gustav Heye Center]] of the [[National Museum of the American Indian]] and is located at 1 Bowling Green.<ref>{{cite web|title=Alexander Hamilton U.S. Custom House|url=https://www.gsa.gov/historic-buildings/alexander-hamilton-us-custom-house-new-york-ny|work=gsa.gov|access-date=6 April 2018}}</ref><ref>{{cite web|url=https://www.google.com/maps/place/Alexander+Hamilton+U.S.+Custom+House/@40.7039989,-74.0158592,17z/data=!3m1!4b1!4m5!3m4!1s0x89c25a13e83761a3:0x9850ef769399a33d!8m2!3d40.7039989!4d-74.0136705 |title=Alexander Hamilton U.S. Custom House |website=[[Google Maps]]}}</ref> Exterior shots for the fifth and final season were filmed at the [[Brooklyn Borough Hall]].

==Logo and motto==
[[File:Mathnet logo and motto.png|thumb|The Mathnet logo and motto]]

[[File:Seal of Los Angeles.svg|thumb|The Los Angeles seal, of which the Mathnet logo is a parody]]

The Mathnet logo is a pastiche of the [[Seal of the City of Los Angeles|Los Angeles city seal]]. The symbols representing the city were replaced with mathematics iconography. The founding date is the year the pilot episode was filmed.

The Mathnet motto "to cogitate and to solve" is a pastiche of the LAPD motto "to protect and to serve."<ref>{{cite web|title=The Origin of the LAPD Motto|url=http://www.lapdonline.org/history_of_the_lapd/content_basic_view/1128 |work=LAPD Online |access-date=8 April 2018}}</ref>

At the conclusion of each episode, a title screen displays the Mathnet logo and motto against a blue background. The logo and motto were also featured on the doors of the police cars used in the Los Angeles episodes, mimicking the appearance of actual LAPD police cars.

Despite having their origins in Los Angeles, the show continued to use the logo and motto even after the setting of the show moved to New York City.

==Home media and syndication==
{{unreferenced section|date=July 2012}}
In 1991, GPN released five episodes from the first two seasons on VHS ("The Problem of the Missing Baseball", "The Trial of George Frankly", "The Problem of the Dirty Money", "The Case of the Missing Air", and "The View from the Rear Terrace").

Around the same time, select PBS stations combined parts of an episode to air in primetime. This was done primarily for seasons 3-5 (New York City era), although at least one omnibus from the Leech era was also broadcast. These versions were re-edited so that they would come in at just under an hour long, featured other segments from ''Square One TV'' as "commercials", and newly created end credits, among other differences. Two of the primetime airings were also commercially released as VHS tapes from Republic Pictures in 1994 ("Despair in Monterey Bay" (retitled to "Treasure in Monterey Bay") and "The Case of the Unnatural").

Both ''Mathnet'' and ''Square One'' went off the air in 1994 (it was rerun until then after the final 1992 season was completed), reappearing from 1999 to 2003 on the cable television network [[Noggin (television)|Noggin]], a joint venture of [[Nickelodeon]] and CTW. However, only 65 episodes were leased by the Noggin network. ''Mathnet'' segments also aired on ''[[Phred on Your Head Show]]'' (one of Noggin's original programs).<ref>{{cite web|title=Square One TV Episode 211|url=http://www.tv.com/shows/square-one-tv/episode-211-210986/|work=TV.com|access-date=3 July 2012}}</ref>

==Other media==
A ''Mathnet'' comic briefly appeared in ''[[3-2-1 Contact]]'' magazine.

Six ''Mathnet'' books, based on episodes of the show, were published:

# Casebook 1: The Case of the Unnatural (based on Season 4, Episode 1)
# Casebook 2: Despair in Monterey Bay (based on Season 4, Episode 2)
# Casebook 3: The Case of the Willing Parrot (based on Season 2, Episode 1)
# Casebook 4: The Map With a Gap (based on Season 2, Episode 6)
# Casebook 5: The Case of the Mystery Weekend (based on Season 5, Episode 1)
