Question: What is the hometown of the man who came up with the Alcubierre drive idea?
Context: Yorath is a small island, 151 acre in size, in the South Saskatchewan River just outside the southern boundaries of the city of Saskatoon, Saskatchewan, Canada.  The island is relatively new, and did not exist when the land was first surveyed in 1903.  This island is managed by the Meewasin Valley Authority; it is not accessible by road (although some maps of the area plot a non-existent north-south grid road on the island), but can be seen from the Maple Grove (formally Leisureland) area.  The island is named after Christopher J. Yorath, who in 1913 became the commissioner of Saskatoon.  Yorath is best known for an extensive, forward-thinking planning document published in 1913 that proposed future residential and road layout for Saskatoon, and he originated the idea of the City developing an "Encircling Boulevard"; in 2013 this proposal came to fruition with the completion of the Circle Drive freeway project.  Ironically, Yorath's document proposed the Encircling Boulevard cross through what would later be named Yorath Island; the final Circle Drive passes to the north of the island, which is undeveloped save for a set of power lines that cross the river and the northern tip of the island. The Alcubierre drive or Alcubierre warp drive (or Alcubierre metric, referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by Mexican theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve apparent faster-than-light travel if a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created. IXS "Enterprise", named after Starship "Enterprise" from the "Star Trek" fictional franchise, is a conceptual interstellar superluminal spacecraft designed by NASA scientist Dr. Harold G. White, revealed at SpaceVision 2013, designed for the goal of achieving warp travel.  The conceptual spacecraft would be a modified version of the Alcubierre drive.  Dr. White is currently running the White–Juday warp-field interferometer experiment in order to develop a proof of concept for Alcubierre-style warp travel, if possible.  The Alcubierre drive uses exotic matter (not to be confused with antimatter) to travel faster than light. Stony Man Mountain, also known as Stony Man, is a mountain in Shenandoah National Park, Virginia and is the most northerly 4,000 foot peak in the Blue Ridge Mountains.  Its maximum elevation is 4,011 feet or 1,223 meters above sea level with a clean prominence of 651 feet.  The mountain is co-located in Madison and Page counties and is easily accessed from Skyline Drive by hiking trails.  Along with Hawksbill Mountain (4,051 feet), it is only one of two peaks in the park higher than 4,000 feet.  The shortest route to the summit is from the Skyland Resort and gains less than 400 vertical feet in about 1 kilometer.  A longer, more challenging, route is from the Skyline Drive trail head at about milepost 39 of the Skyline Drive and gains almost 800 feet.  The peak sits just southeast of the Appalachian Trail (AT) but the summit is accessible from the AT by previously mentioned spur trails.  On the upper slopes of Stony Man one can see a few balsam fir trees which typically grow in more northerly latitudes.  The mountain is composed of ancient basalt which was metamorphosed into Greenstone through heat and pressure. Miguel Alcubierre Moya (born March 28, 1964 in Mexico City) is a Mexican theoretical physicist. Friedrich Schiller developed the concept of the play drive, a conjoining through contradiction of man's experience of the infinite and finite, freedom and time, sense and reason, life and form.  The object of the play drive is the living form, and in contemplation of the beautiful it allows man to become most human.  To understand how he comes to this conclusion, it is important to trace the origins of life and form, as a function of the two drives that the play drive mediates: the form drive and the sense drive.  These two drives are themselves functions of man's person and condition, which Schiller initially describes in terms of the absolute and time. The Idea (French: "Idée, sa naisance, sa vie, sa mort" , "Idea, her birth, her life, her death") is a 1920 wordless novel by Flemish artist Frans Masereel (1889–1972).  In eighty-three woodcut prints, the book tells an allegory of a man's idea, which takes the form of a naked woman who goes out into the world; the authorities try to suppress her nakedness, and execute a man who stands up for her.  Her image is spread through the mass media, inciting a disruption of the social order.  Filmmaker Berthold Bartosch made an animated adaptation in 1932. Peter Lymburner Robertson (December 10, 1879 – September 28, 1951) was a Canadian inventor, industrialist, salesman, and philanthropist who popularized the square-socket drive for screws, often called the Robertson drive.  Although a square-socket drive had been conceived decades before (having been patented in 1875 by one Allan Cummings of New York City, ), it had never been developed into a commercial success, because the design was difficult to manufacture, and Robertson's efficient manufacturing technique using cold forming for the screw's head is what made the idea a commercial success.  He produced his screws (patented in Canada in 1909) in his Milton, Ontario factory starting in 1908.  The brand has been sold over the years, and the manufacturing for the present corporation (Robertson Inc.) is done in Jiaxing, Zhejiang, China; but the Milton, Ontario, building was still a head office for a long time before moving to nearby Burlington, Ontario. Harold G. "Sonny" White is a mechanical engineer, aerospace engineer and applied physicist who is the Advanced Propulsion Team Lead for the NASA Engineering Directorate and is known for proposing new Alcubierre drive concepts and promoting advanced propulsion projects, under development at the NASA Johnson Space Center, including the first practical experiment to test the existence of Alcubierre drive effects. "The history of public baths begins in Greece in the sixth century B.C.," said by Françoise de Bonneville in his book "The Book of the Bath."  Greeks original form of bathing consisted of nothing more than a quick plunge into icy water until the people of Laconica came upon the idea of a hot-air bath.  The hot-air bath later came to be known as a laconica bath.  The people of Laconica were from the Sparta area.  With this bath came the idea of a Spa along with public bathing.
