The T-1000, also known as a Prototype Series 1000 Terminator, is a fictional character in the Terminator franchise.
 A shapeshifting android assassin, the T-1000 is the main antagonist of "", as well as a supporting antagonist in "" and "Terminator Genisys".
 A similar Terminator, referred to as a T-1001 appears in the Fox television series, "".
John Connor is a fictional character of the "Terminator" franchise.
 Created by writer and director James Cameron, the character is first referred to in the 1984 film "The Terminator" and first appears in its 1991 sequel "" initially portrayed by Michael Edwards (briefly as the older Connor) and then by teenage actor Edward Furlong throughout the remainder of the film; in addition, Linda Hamilton's real-life son Dalton Abbot played John as a toddler in a dream sequence.
 The character is subsequently portrayed by 23-year-old Nick Stahl in the 2003 film "" and by 19-year-old Thomas Dekker in the 2008 television series "".
 English actor Christian Bale portrays 33-year-old Connor in the film series's fourth installment, "Terminator Salvation", and Australian actor Jason Clarke portrays a 44-year-old Connor, who becomes the T-3000 and serves as the antagonist of the film series's fifth installment, "Terminator Genisys".
The Terminator is a 1984 American science-fiction action film directed by James Cameron.
 It stars Arnold Schwarzenegger as the Terminator, a cyborg assassin sent back in time from 2029 to 1984 to kill Sarah Connor (Linda Hamilton), whose son will one day become a savior against machines in a post-apocalyptic future.
 Michael Biehn plays Kyle Reese, a soldier from the future sent back in time to protect Connor.
 The screenplay is credited to Cameron, along with producer Gale Anne Hurd.
 Executive producers John Daly and Derek Gibson of Hemdale Film Corporation were instrumental in the film's financing and production.
Liquid mirror telescopes are telescopes with mirrors made with a reflective liquid.
 The most common liquid used is mercury, but other liquids will work as well (for example, low melting alloys of gallium).
 The liquid and its container are rotated at a constant speed around a vertical axis, which causes the surface of the liquid to assume a paraboloidal shape, suitable for use as the primary mirror of a reflecting telescope.
 The rotating liquid assumes the paraboloidal shape regardless of the container's shape.
 To reduce the amount of liquid metal needed, and thus weight, a rotating mercury mirror uses a container that is as close to the necessary parabolic shape as possible.
 Liquid mirrors can be a low cost alternative to conventional large telescopes. Compared to a solid glass mirror that must be cast, ground, and polished, a rotating liquid metal mirror is much less expensive to manufacture.
Terminator Genisys is a 2015 American science fiction film directed by Alan Taylor and written by Laeta Kalogridis and Patrick Lussier.
 The fifth installment in the "Terminator" franchise, it serves as a soft reboot to the film series, using the plot element of time travel to erase the events of the previous films of the franchise from the series' continuity.
 It stars Arnold Schwarzenegger, who reprises his role as the eponymous character, Jason Clarke, Emilia Clarke and Jai Courtney.
 The plot follows soldier Kyle Reese in the war against Skynet; Kyle is sent from the year 2029 to 1984 by John Connor, leader of the Human Resistance, to protect Connor's mother Sarah.
 When Kyle arrives in the past, he discovers that the timeline has been altered and Sarah has been raised by a reprogrammed Terminator.
XM Liquid Metal (or XMLM for short) was a channel on XM Satellite Radio channel 42.
 This XM Radio Channel is Uncensored and had an "xL" Marking, which Means it had Explicit Language.
 The channel played a variety of Hard Metal and Extreme Metal from yesterday and today.
 The channel has been with XM Radio since day one, and has gone through a few phases since.
 On November 12, 2008, as part of the Sirius XM Merger, XM Liquid Metal merged with Hard Attack to form Liquid Metal.
A liquid metal cooled nuclear reactor, liquid metal fast reactor or LMFR is an advanced type of nuclear reactor where the primary coolant is a liquid metal.
 Liquid metal cooled reactors were first adapted for nuclear submarine use but have also been extensively studied for power generation applications.
Liquid metal embrittlement, also known as liquid metal induced embrittlement, is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when exposed to specific liquid metals.
 Generally, a tensile stress, either externally applied or internally present, is needed to induce embrittlement.
 Exceptions to this rule have been observed, as in the case of aluminium in the presence of liquid gallium.
 This phenomenon has been studied since the beginning of the 20th century.
 Many of its phenomenological characteristics are known and several mechanisms have been proposed to explain it.
 The practical significance of liquid metal embrittlement is revealed by the observation that several steels experience ductility losses and cracking during hot-dip galvanizing or during subsequent fabrication.
 Cracking can occur catastrophically and very high crack growth rates have been measured.
Kyle Reese (Sergeant, Tech-Com, DN38416) is a fictional character in the "Terminator" franchise, who serves as the main protagonist in the first and fifth films, with a supporting role in other works.
 He is the father and a subordinate of John Connor and a love interest of Sarah Connor.
 The character is portrayed by Michael Biehn in "The Terminator", Jonathan Jackson in "", Anton Yelchin played him as a teenager in "Terminator Salvation", and Australian actor Jai Courtney portrays him in "Terminator Genisys".
Terminator 2: Judgment Day (also referred to as Terminator 2 or T2) is a 1991 American science-fiction action film co-written, produced and directed by James Cameron.

 It is the sequel to the 1984 film "The Terminator", and the second installment in the "Terminator franchise".
 "Terminator 2" follows Sarah Connor (Hamilton) and her ten-year-old son John (Furlong) as they are pursued by a new, more advanced Terminator, the liquid metal, shapeshifting T-1000 (Patrick), sent back in time to kill John Connor and prevent him from becoming the leader of the human resistance.
 A second, less advanced Terminator (Schwarzenegger) is also sent back in time to protect John.
