Kaluza
Proper noun
Meaning
Kaluza (plural Kaluzas)
A surname.
Examples
Kaluza also set the scalar field equal to a constant, in which case standard general relativity and electrodynamics are recovered identically.
Computing the scalar curvature of this bundle metric, one finds that it is constant on each fiber: this is the "Kaluza miracle".
In 1919, work by Theodor Kaluza showed that by passing to five-dimensional spacetime, one can unify gravity and electromagnetism into a single force.
Indeed, Kaluza did not assume it.
In the Kaluza theory, the gravitational constant can be understood as an electromagnetic coupling constant in the metric.
It has been an objection to the original Kaluza hypothesis to invoke the fifth dimension only to negate its dynamics.
