Acoustics Today
A Publication of the Acoustical Society of America
Volume 6, Issue 3 July 2010
Cover: In viewing M. C. Escher’s lithograph Ascending and Descending shown on the front cover, we see monks plodding up and down an endless staircase—each monk will ultimately arrive at the place where he began his impossible journey. Our perceptual system insists on this interpretation, even though we know it to be incorrect. (M.C. Escher's “Ascending and Descending” ©2010 The M.C. Escher Company-Holland.
