"Home and Away" is an Australian television soap opera.
 It was first broadcast on the Seven Network on 17 January 1988.
 The following is a list of characters that appeared or will appear in 2017, by order of first appearance.
 All characters are introduced by the soap's executive producer, Lucy Addario.
 The 30th season of "Home and Away" began airing from 30 January 2017.
 Riley Hawkins was introduced during the following episode.
 Scarlett Snow made her debut in May, while June saw the arrival of the four-strong Astoni family consisting of parents Ben and Maggie Astoni, and their daughters Coco and Ziggy Astoni.
 Robbo made his first appearance in July, while Beth Ellis was introduced in August.
Snow grooming is the process of manipulating snow for recreational uses with a tractor, snowmobile, piste caterpillar, truck or snowcat towing specialized equipment.
 The process is used to maintain ski hills, cross country ski trails and snowmobile trails by grooming (moving, flattening, rototilling, or compacting) the snow on them.
 A snow groomer is usually employed to pack snow and improve skiing and snowboarding and snowmobile trail conditions.
 The resulting pattern on the snow is known as corduroy, and is widely regarded as a good surface on which to ski or ride.
 Snow groomers can also move accumulated snow made by snow machines as part of a process, called "snow farming".
Michael Snow, {'1': ", '2': ", '3': ", '4': "} (born December 10, 1929) is a Canadian artist working in painting, sculpture, video, films, photography, holography, drawing, books and music.
 His best-known films are "Wavelength" (1967) and "La Région Centrale" (1971), with the former regarded as a milestone in avant-garde cinema.
Percy Lee Snow (born November 5, 1967) is a retired American football linebacker who played at Michigan State University and was a first-round draft pick of the Kansas City Chiefs.
 Snow made the College Football All-America Team at Michigan State and was voted the player of the game in the 1988 Rose Bowl.

Zorns Lemma is a 1970 American structural experimental film by Hollis Frampton.
 Originally starting as a series of photographs, the non-narrative film is structured around a 24-letter Latin alphabet.
 It remains, along with Michael Snow's "Wavelength" and Tony Conrad's "The Flicker", one of the best known examples of structural filmmaking.
In a single-mode optical fiber, the zero-dispersion wavelength is the wavelength or wavelengths at which material dispersion and waveguide dispersion cancel one another.
 In all silica-based optical fibers, minimum material dispersion occurs naturally at a wavelength of approximately 1300 nm.
 Single-mode fibers may be made of silica-based glasses containing dopants that shift the material-dispersion wavelength, and thus, the zero-dispersion wavelength, toward the minimum-loss window at approximately 1550 nm.
 The engineering tradeoff is a slight increase in the minimum attenuation coefficient.
 Such fiber is called dispersion-shifted fiber.
Peter Zeitlinger A.S.C. (born 6 June 1960 in Prague) is an Czechoslovakian-born Austrian cinematographer, who has worked with the director Werner Herzog since 1995.
 Their film "Encounters at the End of the World" was nominated for the Academy Award 2009.
 Peter Zeitlinger studied from 1980 - 1987 at the University of Music and Performing Arts, Vienna.
 He was influenced by Michael Snow and Peter Kubelka followed by Vittorio Storaro, Sven Nykvist and Vilmos Zsigmond.
 Zeitlinger's films have received considerable critical acclaim and achieved popularity on the art house circuit.
Peter Lindsay Weir, AM ( ; born 21 August 1944) is an Australian film director.
Wavelength is a 45-minute film that made the reputation of Canadian experimental filmmaker and artist Michael Snow.
 Considered a landmark of avant-garde cinema, it was filmed over one week in December 1966 and edited in 1967, and is an example of what film theorist P. Adams Sitney describes as "structural film", calling Snow "the dean of structural filmmakers."
 "Wavelength" is often listed as one of the greatest underground, art house and Canadian films ever made.
 It was named #85 in the 2001 "Village Voice" critics' list of the 100 Best Films of the 20th Century.
 The film has been designated and preserved as a masterwork by the Audio-Visual Preservation Trust of Canada.
 In a 1969 review of the film published in "Artforum", Manny Farber describes "Wavelength" as "a pure, tough 45 minutes that may become "The Birth of a Nation" in Underground films, is a straightforward document of a room in which a dozen businesses have lived and gone bankrupt.
 For all of the film's sophistication (and it is overpowering for its time-space-sound inventions) it is a singularly unpadded, uncomplicated, deadly realistic way to film three walls, a ceiling and a floor... it is probably the most rigorously composed movie in existence."
The Plumber is a 1979 Australian psychological thriller film about a psychotic plumber who befriends a woman.
 Written and directed by Peter Weir, "The Plumber" was originally made and broadcast as a television film in Australia in 1979 but was subsequently released to theaters in several countries beginning with the United States in 1981.
 The film was made shortly after Weir's critically acclaimed "Picnic at Hanging Rock" became one of the first Australian films to appeal to an international audience.
 The film stars Judy Morris, Ivar Kants, and Robert Coleby, all of them being most notable as actors in Australian soap operas.

Question: Was Peter Weir alive when Michael Snow made "Wavelength"?
Answer: yes
