What is Fringe: Definition and 75 Discussions

Fringe is an American science fiction television series created by J. J. Abrams, Alex Kurtzman, and Roberto Orci. It premiered on the Fox network on September 9, 2008, and concluded on January 18, 2013, after five seasons and 100 episodes. The series follows Olivia Dunham (Anna Torv), Peter Bishop (Joshua Jackson), and Walter Bishop (John Noble), all members of the fictional Fringe Division of the Federal Bureau of Investigation, based in Boston, Massachusetts, under the supervision of Homeland Security. The team uses fringe science and FBI investigative techniques to investigate a series of unexplained, often ghastly occurrences, which are related to mysteries surrounding a parallel universe.
The series has been described as a hybrid of fantasy, procedural dramas and serials, influenced by films like Altered States and television shows such as Lost, The X-Files and The Twilight Zone. The series began as a traditional mystery-of-the-week series and became more serialized in later seasons. Most episodes contain a standalone plot, with several others also exploring the series' overarching mythology.
Critical reception was lukewarm at first but became more favorable after the first season, when the series began to explore its mythology, including parallel universes and alternate timelines. The show, along with cast and crew, were nominated for many major awards. Despite its move to the "Friday night death slot" and low ratings, the series developed a cult following. It also spawned two six-part comic book series, an alternate reality game, and three novels.

    Length of the box based on the fringe pattern? I think I'm close.

    Homework Statement The figure shows a neutron in a one-dimensional box. If the right end of the box is opened, the neutron travels out of the box, impinges on a double slit, and is detected 2.0 m behind the double slit. Repeating the experiment over and over produces the fringe pattern shown...

    Fringe Radius Relation for Small Times t

    1. Show that for t<<R, the radius r of a fringe is related to r= (2TR)^1/2 I'm not sure what the relevant equations are, that would be the problem. A gentle shove in the right direction would be appreciated, I've been looking for exactly how to prove it and I can't. ^_^ Thanks for any help!

    Fringe Field of an asymmetrical parallel capacitor

    I have a problem bothering me for a long time. Here it is: suppose I have an asymmetrical parallel plate capacitor with one electrode much larger than the other.

    Reducing fringe effect, measuring values

    Hi, I'm trying to measure some low capacitance using parallel plates i built. We're probably looking into the pF, say maybe 20pF (with the pcb board etc). The change in capacitance that i am really interested is very small. For the moment, i have use water as my dielectric. The capacitance...

    What is the significance of a fringe shift in Fizeau's experiment?

    I'm working on a modification of Fizeau's experiment in 1851 about the addition of velocities. I've derived the formula for the fringe shift. But the problem is I actually don't know what it is. I know it's the movement of the interference pattern. But it has no unite, so what is the meaning of...
