Space-time vs. Spacetime
Examples of use of
spacetime:
- Weisstein's encyclopedia http://www.treasure-troves.com/physics/
- D. J. Griffiths' Introduction to Electrodynamics (Upper Saddle River, N. J.: Prentice-Hall, 1989)
- numerous books with spacetime in title
- E. F. Taylor and J. A. Wheeler, Spacetime Physics (San Francisco: W. H. Freeman, 1966)
- Caltech class: "Spacetime 101"
- .edu matches online are almost exclusively for spacetime
Examples of use of space-time:
The Spacetime four vector
The space-time four vector is:
[x y z ct]
the use of the vector as:
[x y z ict]
was common about 40 years ago or so, but it is now considered archaic and the former notation is prefered.--BlackGriffen
However, there are certainly physicists who prefer the i notation, including [Jack Sarfatti].
