    I just asked about the pronunciation, not the meaning. Anyway, thank you... I guess...

    You said that the speed of push was the speed of sound, and then displayed it as "761 mph". But isn't that the speed of air through air? Isn't the speed of push, the speed of sound through the object that's being pushed?
