              HIGH-TECH EAVESDROPPING ON THE GANGES RIVER DOLPHIN SONAR

               SIGNALS HOLD CLUES THAT COULD SAVE AN ENDANGERED SPECIES

      The Ganges river dolphin is one of only two remaining freshwater dolphin species on Earth. But pollution, fishing, and dams threaten to wipe it out entirely.

      So acoustical engineer Harumi Sugimatsu and her team have deployed an experimental sonar monitoring system just under the surface of the murky water. The hope is to track the dolphins by the high-frequency clicks they use to navigate and hunt. By eavesdropping on their underwater lives, Sugimatsu believes she can gather data about their behavior and geographical range—data that conservationists can use in their struggle to keep the species from going extinct.

      When he was 19, in 1898, Albert Einstein was refused a place at the Munich Technical Institute because he 'showed no promise'. Three years later, Einstein took Swiss citizenship and became an examiner at the Swiss Patent Office. In his spare time, he continued his study of physics and by 1905 had advanced so far that he was able to publish the first of his celebrated papers on the theory of relativity which earned worldwide fame.
