Excerpt: Georg von Békésy (Békésy György) (June 3, 1899 June 13, 1972) was a Hungarian biophysicist born in Budapest. In 1961, he was awarded the Nobel Prize in Physiology or Medicine for his research on the function of the cochlea in the mammalian hearing organ. Békésy developed a method for dissecting the inner ear of human cadavers while leaving the cochlea partly intact. By using strobe photography and silver flakes as a marker, he was able to observe that the basilar membrane moves like a surface wave when stimulated by sound. Because of the structure of the cochlea and the basilar membrane, different frequencies of sound cause the maximum amplitudes of the waves to occur at different places on the basilar membrane along the coil of the cochlea. He concluded that his observations showed how different sound wave frequencies are locally dispersed before exciting different nerve fibers that lead from the cochlea to the brain. He theorized that the placement of each sensory cell (hair cell) along the coil of the cochlea corresponds to a specific frequency of sound (the so-called tonotopy). Békésy later developed a mechanical model of the cochlea, which confirmed the concept of frequency dispersion by the basilar membrane in the mammalian cochlea. But this model could not provide any information as to a possible function of this frequency dispersion in the process of hearing. In a posthumous 1974 article looking back over progress in the field, he remarked "In time, I came to the conclusion that the dehydrated cats and the application of Fourier analysis to hearing problems became more and more a handicap for research in hearing," referring to th...More: http://booksllc.net/?id=579799 ...

Excerpt: Glenn Durland Paige (born June 28, 1929) is an American political scientist. He is a Professor Emeritus of political science at the University of Hawaii and Chair of the Governing Council of the Center for Global Nonkilling. Paige is known for developing the concept of nonkilling, his studies on political leadership, and the study of international politics from the decision-making perspective with a case study of President Harry S. Truman's decision to involve the United States in the Korean War. The son of a YMCA social worker, Glenn Durland Paige was born on June 28, 1929 in Brockton, Massachusetts, in the northeastern part of the United States known as New England. He grew up in Rochester, New Hampshire, with summers in Provincetown, Cape Cod, Massachusetts. He served in the U.S. Army (1948-...More: http://booksllc.net/?id=22135863 ... Read more
