An exploration of echo not as simple repetition but as an agent of creative possibilities. In this volume in the MIT Press Essential Knowledge series, Amit Pinchevski proposes that echo is not simple repetition and the reproduction of sameness but an agent of change and a source of creation and creativity. Pinchevski views echo as a medium, connecting and mediating across and between disparate domains. He reminds us that the mythological Echo, sentenced by Juno to repeat the last words of others, found a way to make repetition expressive. So too does echo introduce variation into sameness, mediating between self and other, inside and outside, known and unknown, near and far. Echo has the potential to bring back something unexpected, either more or less than what was sent. Pinchevski distinguishes echo from the closely related but sometimes conflated reflection, reverberation, and resonance; considers echolalia as an active, reactive, and creative vocalic force, the launching pad of speech; and explores echo as a rhetorical device, steering between appropriation and response while always maintaining relation. He examines the trope of echo chamber and both destructive and constructive echoing; describes various echo techniques and how echo can serve practical purposes from echolocation in bats and submarines to architecture and sound recording; explores echo as a link to the past, both literally and metaphorically; and considers echo as medium using Marshall McLuhan’s tetrad.

Never to Return is the harrowing tale of the torpedoing and sinking of a Coast Guard ship and the loss of 171 Coast Guardsmen off the coast of Iceland during WWII. The USS Leopold was a U.S. Coast Guard destroyer escort in a convoy of merchant ships carrying war materiel to England, on the lookout for the deadly U-boat wolf packs lurking in the North Atlantic. The Leopold was largely unarmored, lightly armed, and no match for the U-255’s torpedoes. Never to Return is the story of gunner Sparky Nersasian and his shipmates’ struggles to survive the Leopold’s sinking.
Fundamentals of sonar systems are presented in this book, prepared for both regular navy and naval reserve personnel who are seeking advancement in rating. An introductory description is first made of submarines and antisubmarine units. Determination of underwater targets is analyzed from the background of true and relative bearings, true and relative motion, and computation of target angles. Then, applications of both active and passive sonars are explained in connection with bathythermographs, fathometers, tape recorders, fire control techniques, internal and external communications systems, maintenance actions, test methods and equipment, and safety precautions. Basic principles of sound and temperature effects on wave propagation are also discussed. Illustrations for explanation use, information on training films and the sonar technician rating structure are also provided.
