Advanced Subspace Geometry

From Memory Alpha, the free Star Trek reference.

Advanced Subspace Geometry is one of the geometry courses taught at Starfleet Academy.

Tom Paris said that Advanced Subspace Geometry was the only class at the Academy where he actually paid attention. This came in handy in 2374, when USS Voyager encountered an unstable coaxial warp ship. (VOY: "Vis à Vis")
