Fixed points in time, or temporal nexuses, (AUDIO: Forever Fallen) were moments in the space-time continuum at which events were set in stone and could never, ever be changed, no matter what, with dire consequences if such a thing happened.
What is an example of a fixed point?
A set of fixed points is sometimes called a fixed set. Not all functions have fixed points: for example, f(x) = x + 1, has no fixed points, since x is never equal to x + 1 for any real number. A fixed point is a periodic point with period equal to one.
Why is Jack a fixed point in time?
An anomaly as a fixed point in that he is an immortal instead of an event, Captain Jack became a fixed point when he was resurrected by Rose Tyler, although he briefly lost his immortality when the rest of the world became immortal in the episode Miracle Day.
What is a fixed point reference?
A fixed point of reference is something that is consistent and does not change. One example is the North Star. Even centuries ago, sailors would use an instrument called a sextant and as long as they could see the North Star and the horizon, they could calculate exactly where they were.
What are fixed points used for?
Fixed points are used in calibrating thermometers. To calibrate a thermometer is to mark a thermometer so that you can use it to measure temperature accurately. A fixed point is a standard degree of hotness or coldness such as the melting point of ice or boiling point of water.
How do you find fixed points?
Geometrically, the fixed points of a function y = g (x) are the points where the graphs of y = g (x) and y = x intersect. In theory, finding the fixed points of a function g is as easy as solving g (x) = x. The fixed points can also be found on figure 1, by looking at the intersection of y = x and y = x2 − 2.
How do you show a fixed point?
Let f be a continuous function on [0,1] so that f(x) is in [0,1] for all x in [0,1]. Then there exists a point p in [0,1] such that f (p) = p, and p is called a fixed point for f. Proof: If f(0) = 0 or f(1) = 1 we are done.
How did the Doctor survive the fixed point?
That didn’t stop others from attempting to kill him, however, as when Gantok prepared to kill him in revenge for being beaten at live chess, the Doctor was saved from being shot by his non-destined killer by a trap hole that fed Gantok to the ravenous skulls of the Headless Monks.
What is Doctor Who Time Lord Victorious?

What is the point of Doctor Who?
Doctor Who is a British science fiction television programme broadcast by BBC One since 1963. The programme depicts the adventures of a Time Lord called the Doctor, an extraterrestrial being who appears to be human. The Doctor explores the universe in a time-travelling space ship called the TARDIS.
What is the fixed point called?
A circle is the set of points in a plane that are all the same distance from a fixed point in the plane. The fixed point is called the centre of the circle.
What is a fixed point in analysis?
Definition. A fixed point is a point x such that. f(x) = x. Graphically, these are exactly those points where the graph of f, whose equation. is y = f(x), crosses the diagonal, whose equation is y = x.
What is fixed point equation?
Fixed point: A point, say, s is called a fixed point if it satisfies the equation x = g(x). Fixed point Iteration: The transcendental equation f(x) = 0 can be converted algebraically into the form x = g(x) and then using the iterative scheme with the recursive relation.
What is a fixed point in physics?
n. 1. ( General Physics) physics a reproducible invariant temperature; the boiling point, freezing point, or triple point of a substance, such as water, that is used to calibrate a thermometer or define a temperature scale.
What is the lower fixed point?
The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure.
What is fixed point calibration?
The fixed point calibration, in contrast to the comparative calibration, is carried out against the defined triple, freezing and melting points from the International Temperature Scale of 1990 (ITS-90). The fixed points define temperatures at which the physical state of substances alter.
