If you collapse the time axis to a single pont, the parabola becaomes a line segment-this is an example of what mathematicians call " projection ".
22.
And the time axis will also shift, since everything is also occurring at a different time early or later depending on the relative direction of motion.
23.
Hamiltonian non-autonomous mechanics is formulated as covariant Hamiltonian field theory on fiber bundles over the time axis, i . e . the real line !.
24.
Normally, the time axis is drawn vertically from top ( start of project ) to bottom ( end of project ), and the location axis is drawn horizontally.
25.
Separate events are considered to be " timelike " if they are separated across the time axis, or " spacelike " if they differ along the space axis.
26.
As it turns out, string theories involve higher-dimensional spaces than the 3D world with which we are familiar; bosonic string theory requires 25 spatial dimensions and one time axis.
27.
That trick doesn't really work for 4D objects because we still only have one time axis to play with-so the third dimension still has to be projected down into 2D.
28.
All timelike world lines of slower-than-light objects will at every point have a slope closer to the vertical time axis ( the " T " coordinate ) than 45 degrees.
29.
Both the war-time Axis occupational authorities and the post-war communist authorities ran concentration / prison camps in the territory of Vojvodina . ( see List of concentration and internment camps ).
30.
Unlike sequential games, simultaneous games do not have a time axis as players choose their moves without being sure of the other's, and are usually represented in the form of payoff matrices.
