Shock Waves
A shock wave is a compressional force that is created by an abrupt change in fluid properties such as pressure, temperature, and density. Shockwaves can be established in two types of flows: subsonic and supersonic. The subsonic flow is adjusted by changes in the flow properties while the supersonic flow is the adjusted through the change of the presence of an object.

Famous quotes containing the words shock and/or waves:
“Children demand that their heroes should be fleckless, and easily believe them so: perhaps a first discovery to the contrary is less revolutionary shock to a passionate child than the threatened downfall of habitual beliefs which makes the world seem to totter for us in maturer life.”
—George Eliot [Mary Ann (or Marian)
“There is no sea more dangerous than the ocean of practical politics—none in which there is more need of good pilotage and of a single, unfaltering purpose when the waves rise high.”
