      1581, Galileo began studying at the University of Pisa University of Pisa, 
      where his father hoped he would study medicine. While at the University 
      of Pisa, Galileo began his study of the <a HREF="../sci/instruments/pendulum.html">pendulum</A> 
      while, according to legend, he watched a suspended lamp swing back and forth 
      in the cathedral of Pisa. However, it was not until 1602 that Galileo made 
      his most notable discovery about the pendulum - the period (the time in 
      which a pendulum swings back and forth) does not depend on the arc of the 
      swing (the isochronism). Eventually, this discovery would lead to Galileo's 
      further study of time intervals and the development of his idea for a<BR>
      pendulum clock. </TD>
