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:
“Beware the/easy griefs, that fool and fuel nothing./It is too easy to cry “AFRIKA!”/and shock thy street,/and purse thy mouth,/and go home to thy “Gunsmoke,” to/thy “Gilligan’s Island” and the NFL.”
—Gwendolyn Brooks (b. 1917)
“It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys.”
—Emmuska, Baroness Orczy (1865–1947)
