Bart Allen

Bartholomew Henry "Bart" Allen II is a fictional superhero in the DC Comics Universe. Allen first appeared as the superhero Impulse, a teenage sidekick of the superhero the Flash, before later on becoming the second hero known as Kid Flash. The character first made a cameo appearance in The Flash #91 in 1994, while his first full appearance in issue #92, and appeared as the lead character in Impulse (1995–2002) and The Flash: The Fastest Man Alive (2006–2007). In the latter series, the character became the fourth hero to assume the identity of The Flash. Bart also prominently features in the superhero team titles Young Justice and Teen Titans. As the Flash, Bart was also a core character in 10 issues of Justice League of America.

As first conceived by writers, Bart was born in the 30th century to Meloni Thawne and Don Allen, and is part of a complex family tree of superheroes and supervillains. His father, Don, is one of the Tornado Twins and his paternal grandfather is Barry Allen, the second Flash. His paternal grandmother, Iris West Allen, is also the adoptive aunt of the first Kid Flash, Wally West (Bart's first cousin once removed). Additionally, Bart is the first cousin of XS, a Legionnaire and daughter of Dawn Allen. On his mother's side, he is a descendant of supervillains Professor Zoom and Cobalt Blue as well as the half-brother of Owen Mercer, the second Captain Boomerang. In addition to these relatives, he had a supervillain clone known as Inertia.

Flash (novel)

Flash is a science fiction novel by L. E. Modesitt published in 2004.

Plot introduction

Flash is set in a future Earth of unspecified year; most likely 24th century as in its predecessor Archform: Beauty. Humanity is still recovering from environmental disasters of the 21st century, but technology provides enough material resources for everyone. Earth's old nations have merged into continental governments - such as NorAm, United Europe, and Sinoplex - many of which are partially or wholly under the sway of various multinational corporations. Various wars are in progress, including an independence movement of colonists on Mars.

The protagonist is Jonat DeVrai, a talented market research consultant and former Marine Corps officer who happens to have retained nanite combat enhancements that should be removed from retiring soldiers. As usual in Modesitt's books, DeVrai does not seek power; he is forced to exercise it because of others' attempts to use him in their designs to gather power to themselves.

Fix (position)

In position fixing navigation, a position fix (PF) or simply a fix is a position derived from measuring external reference points.

In nautical applications, the term is generally used with manual or visual techniques such as the use of intersecting visual or radio position lines rather than the use of more automated and accurate electronic methods such as GPS; in aviation, use of electronic navigation aids is more common. A visual fix can be made by using any sighting device with a bearing indicator. Two or more objects of known position are sighted, and the bearings recorded. Bearing lines are then plotted on a chart through the locations of the sighted items. The intersection of these lines is then the current position of the vessel.

Usually, a fix is where two or more position lines intersect at any given time. If three position lines can be obtained, the resulting "cocked hat", where the 3 lines do not intersect at the same point, but create a triangle where the vessel is inside, gives the navigator an indication of the accuracy in the three separate position lines.
