      In 1592, Galileo was appointed professor of mathematics at the University 
      of Padua. While teaching there, he frequently visited a place called the 
      Arsenal, where Venetian ships were docked and loaded. Galileo had always 
      been interested in mechanical devices. Naturally, during his visits to the 
      Arsenal, he became fascinated by nautical technologies, such as the <a href="../sci/instruments/sector.html">sector</a> 
      and shipbuilding. In 1593, he was presented with the problem involving the 
      placement of oars in galleys. He treated the oar as a lever and correctly 
      made the water the fulcrum. A year later, he patented a model for a <a href="../sci/instruments/pump.html">pump</a>. 
      His pump was a device that raised water by using only one horse. </TD>
