In the theory of 3-manifolds, a compression body is a kind of generalized handlebody. A compression body is either a handlebody or the result of the following construction: Let be a compact, closed surface (not necessarily connected). Attach 1-handles to along . Let be a compression body. The negative boundary of C, denoted , is . (If is a handlebody then .) The positive boundary of C, denoted , is minus the negative boundary. There is a dual construction of compression bodies starting with a surface and attaching 2-handles to . In this case is , and is minus the positive boundary. Compression bodies often arise when manipulating Heegaard splittings. (Wikipedia).

Longitudinal and Transverse Waves
A longitudinal or compression wave is created by a disturbance that is along the direction the wave will travel. A transverse wave is created by a disturbance that is perpendicular to the direction the wave will travel.

What is length contraction? Length contraction gives the second piece (along with time dilation) of the puzzle that allows us to reconcile the fact that the speed of light is constant in all reference frames.
