Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach1). For objects traveling in dry air of a temperature of 20°C (68°F) at sea level, this speed is approximately 343.2m/s, 1,125 ft/s, 768mph, 667knots, or 1,235km/h. Speeds greater than five times the speed of sound (Mach5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach0.8 and Mach1.23.
Sounds are traveling vibrations in the form of pressure waves in an elastic medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, Mach numbers for aircraft may change despite a constant travel speed. In water at room temperature supersonic speed can be considered as any speed greater than 1,440m/s (4,724ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities.
Supersonic was a British children's television music show which featured pop music artists of the day. Launched in 1975, it was produced by London Weekend Television for the ITV network and ran for two years. The show typically lasted 30 minutes and was broadcast, firstly, on Thursday afternoons - Series 1, Show 1: (4 September 1975) - Series 1, Show 18: The Supersonic Christmas Show 1975 (25 December 1975.) It was then moved to a Saturday afternoon slot from Series 1, Show 19: (3 January 1976.) The programme was devised and created by David Deyong
and presented by film and music producer Mike Mansfield and the main theme was composed and sung by Andy Bown.
Although the show starred performers with songs in the music charts, the show, unlike its BBC rival Top of the Pops, was not chart-based. Whilst Top of the Pops ran all year, Supersonic had a limited run with season one consisting of 30 editions and season two consisting of 28.
The show was recorded in front of an audience of children at London Weekend's studios, then known as the South Bank Television Centre and used a laissez-faire style of production in which cameras were highly visible and areas such as the production gallery were featured. Its host also doubled up as producer and director, cueing in performances from the studio gallery instead of presenting conventional links to camera.
Death Note is a 37-episode anime series based on the manga series of the same title written by Tsugumi Ohba and illustrated by Takeshi Obata. Death Note aired in Japan on the Nippon Television (NTV) network every Tuesday, from October 3, 2006, to June 26, 2007. The plot of the series primarily revolves around high school student Light Yagami, who decides to rid the world of evil with the help of a supernatural notebook titled Death Note. This book causes the death of anyone whose name is written in it and is passed on to Light by the God of Death (or Shinigami) Ryuk after he becomes bored within the Shinigami world.
A three-hour "Director's Cut" compilation TV special, titled "Death Note: Relight: Visions of a God", aired on NTV a few months after the anime concluded. Although advertised to be the "complete conclusion", the popularity of the series inspired the release of a second TV special, titled "Death Note: Relight 2: L's Successors" nearly a year later. These specials recap the first and second arcs of the anime respectively, with new scenes added to fill in any plot holes resulted from omitted footage.
