	Time Supplement [Internet Encyclopedia of Philosophy]
		Minkowski meant it is fundamental in the sense that the spacetime interval between any two events is intrinsic to spacetime and does not vary with the reference frame, unlike a distance (space) or a duration (time).
		Minkowski diagrams are diagrams of a Minkowski space, which is a spacetime satisfying the Special Theory, and therefore it is falsely presupposed that physical processes such as gravitational processes have no effect on the structure of spacetime.
		Minkowski was the first person to construct such a mathematical space, and he was the first person to call time the fourth dimension, because it was the fourth dimension of his abstract space for spacetime.

	Minkowski diagram - Wikipedia, the free encyclopedia
		The Minkowski diagram is a graphical tool used in special relativity to visualize spacetime with regard to an inertial reference frame.
		A Minkowski diagram is a representation of Minkowski space in an inertial reference frame.
		Examination of a Minkowski diagram shows this effect is caused by a tilting relationship between two reference frames in space-time.

	Minkowski, mathematiciens, and the mathematical theory of relativity (Site not responding. Last check: 2007-10-08)
		Minkowski's 1908 Cologne lecture "Raum und Zeit" (Minkowski 1909) may be understood as an effort to extend the disciplinary frontier of mathematics to include the principle of relativity.
		Minkowski openly recognized the role-albeit a heuristic one-of experimental physics in the discovery of the principle of relativity.
		Minkowski was ultimately unable to detach his theory from that of Einstein, because even if he convinced some mathematicians that his work stood alone, the space-time theory came to be understood by most German physicists as a purely formal development of Einstein's theory.

	Hermann Minkowski - Avoo - Ask Us A Question - Hermann Minkowski (June 22, 1864 – January 12, 1909 in Göttingen) was ... (Site not responding. Last check: 2007-10-08)
		Hermann Minkowski (June 22, 1864 – January 12, 1909 in Göttingen) was a German mathematician who developed the geometry of numbers and who used geometrical methods to solve difficult problems in number theory, mathematical physics, and the theory of relativity.
		Hermann Minkowski was born in Aleksotas (a suburb of Kaunas, Lithuania) to a family of German, Polish, and Jewish descent.
		Minkowski explored the arithmetic of quadratic forms, especially concerning n variables, and his research into that topic led him to consider certain geometric properties in a space of n dimensions.

	2.4 Example: Minkowski space
		The standard conformal diagram for Minkowski space [109] is shown in Figure 2.
		In the case of Minkowski space-time, the metric can be extended in a regular way to three points representing future and past time-like infinity and space-like infinity, but this is not generally so.
		This is, in particular, a property of the space-like hyperboloids in Minkowski space.

	Minkowski Diagrams (Site not responding. Last check: 2007-10-08)
		The defining feature of a Minkowski diagram is that light rays are drawn at a 45 degree angle to the line or plane respresenting space.
		In a Lineland Minkowski Diagram, there is one axis for space (a line), and one axis for time.
		Thus, a Lineland Minkowski Diagram is a plane, with light rays traveling at 45 and 135 degree angles to the space axis (these rays make up a two dimensional light cone).

	The End Game (Site not responding. Last check: 2007-10-08)
		Minkowski had now introduced the basis of what later became the relativistic thesis that the deformations of a moving system are exclusively due to geometrical projections.
		The standard rotation diagrams not only rotate the "t' axis" (which is actually only the positions of the origin clock) clockwise, they also rotate X' counter-clockwise by the same degree.
		Independently of any rotations or co-ordinate systems or spacetime diagrams at all, the hyp-trig equations substitute cosh(r) for gamma and sinh(r) for (gamma v), thus are just an equivalent way of writing the LTE per inertially moving system.

	Hermann Minkowski - Wikipedia, the free encyclopedia
		While still a student at Königsberg, in 1883 he was awarded the Mathematics Prize of the French Academy of Sciences for his manuscript on the theory of quadratic forms.
		Minkowski taught at the universities of Bonn, Göttingen, Königsberg and Zurich.
		He was the brother of Oskar Minkowski (1858-1931), a well-known physician and researcher.

		Minkowski diagram a moving particle's world line asymptotically approaches the pi/4 AF dotted line.
		On a Euclidean space diagram the space and the time axes are simply rotated, however on a Minkowski space diagram, on your diagram, J's space axis turns anti-clockwise and his time axis turns clockwise.
		The only events in your diagram where relativity is relevant is K and N, where light is reflected off a moving mirror without losing speed (like a tennis ball would).

	SparkNotes: Kinematics: Lorentz Transformations and Minkowski Diagrams
		Michelson and Morley's experiments (see the Introduction to this topic) showed that there was no difference in the speed of light when the earth was moving through the ether in different directions, suggesting that there was no such thing as an ether.
		A Minkowski diagram or spacetime diagram is a convenient way of graphically representing the lorentz transformations between frames as a transformation of coordinates.
		The advantage of a Minkowski diagram is that the same worldline applies to both sets of coordinate axes (that is, to x and ct, as well as to x' and ct').

	Being and Becoming in Modern Physics (Stanford Encyclopedia of Philosophy)
		In fact, the temporal interval between two points in the spacetime (and hence the simultaneity of two points in the spacetime) is not defined at all until a coordinate system or frame of reference (with some arbitrarily chosen spacetime point as origin of the frame) is chosen.
		Wilfrid Sellars believed that the various invariant or observer-independent elements of Minkowski spacetime (like the light cone structure to be described below) that are typically given primary consideration in treatments of relativity from a spacetime perspective are abstractions from and secondary to the ‘perspectival’ pictures, the myriad of coordinate systems or reference frames.
		The non-animated Minkowski diagram may be “static”, but, as Park points out, the static diagram represents the evolution in (proper) time of systems along their world lines.

		Referred to as the Minkowski Question Mark, it is well-defined for all real numbers and maps the unit interval into, and onto, the unit interval.
		In this section, we explicitly present a set of self-similarities of the Minkowski Question Mark, and show that this set is a semi-group subset of the Modular group.

	The Symmetry of Relative Motion
		The concept of P being stationary with Q moving is asymmetrical, consistent with the asymmetry of the spacetime diagram of Figure 4.
		The diagram is reassuring that the symmetrical model of relative motion is consistent with the mathematics of relativity.
		However, there is the problem that the diagram is comparing lengths and times according to coordinate system P with those of system Q using the mathematics of a third coordinate system, the orthogonal axis of symmetry.

	The Roots of Consciousness: Theory, Consciousness and the New Physics
		Physicists use a simple geometric picture of the flat spacetime of special relativity called a "Minkowski diagram." Relativity unites space and time into a unified "four dimensional space-time continuum" in which time appears in the distance formula with a sign different from the sign of space.
		Events are conceived of as points on the Minkowski diagram.
		The history of a sequence of events is described by a curve or path on the Minkowski diagram called a world line.

	A Primer On Time Travel
		A Minkowski diagram can show this: You put three-dimensional space on the x-axis, and time on the y.
		Now since light is a constant, it would appear in the Minkowski diagram as a straight, 45-degree line.
		The vertex point of the cones (where the cones meet on the x-axis) is the immediate "here-now." (See A) In this diagram, one's life forms a kind of four-dimensional "worm" in space-time.

	Penrose Diagram
		Often in General Relativity one uses the Penrose diagram to describe the causal structure of the spacetime.
		The major feature of those diagram is to put the infinity at finite position and at the same time do so such that the null geodesics are preserved (we conserve the structure of the spacetime).
		The interest in this diagram is that an asymptotically flat spacetime will have the same structure as infinity and therefore the same diagram at infinity.

		However, the mind is perfectly capable of conceptualizing more than three dimensions, even though they cannot be visualized all at once.

		Three-dimensional space is represented by a flat plane, and a spherical plane surrounding the observer at any given constant distance is represented by a simple ring on the past light-cone.

	The Light Cone: Einstein-Minkowski Spacetime

		In the above diagram, the pink line represents one inertial observer, and he will regard events on the pink plane as simultaneous with each other.
		As Minkowski suggested in his quotation, and as we've been doing all along, space and time are shadows of spacetime.

	The Twin Paradox: The Spacetime Diagram Explanation
		Minkowski said, "Henceforth Space by itself, and Time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality." Minkowski recast Einstein's version of Special Relativity (SR) on a new stage, Minkowski spacetime.
		Here, dt, dx, dy, and dz are all co-ordinate differences between two events that are "near" each other on the Minkowski diagram.
		More generally, suppose someone carrying a high-quality time-piece travels some world-line from event E to event F. "High-quality" here means that acceleration doesn't affect the time-keeping mechanism.

		A Penrose diagram is a diagram of a conformally compactified space-time.
		The region that represents the conformally compactified Minkowski space-time has the same range of suppressed coordinates as the whole space-time, so no information about the conformal infinity is lost in the suppression.
		The space-time diagram in the remaining unsuppressed coordinates is illustrated in Fig.3.
