Velocity in Special Relativity | Four-Velocity

[@budstep7361]

Good explanation, thank you! Especially insightful that tau is lorentz invariant relative to the four velocity.

eew you guys are using eta for the metric? -this message was crated with the support of the g-metric Gang

[@arminth4117]

I could be wrong but I've always seen eta used for Minkowski metric, and g used for any metric often solved from EFEs in general relativity

[@SmajdalfFrogi12]

@@arminth4117 even when we first got introduced to special relativity our professor was using the g notation

[@PrettyMuchPhysics]

eta > g

[@Ranhirok]

The Minkowsky metric is so "special" it has its own simbol, g is just so "general" when we are talking about relativity.
