Notes from Independent Study Meeting
                      Feb 24, 2022

Present: Richmond, Dayal

  - Dayal shows results from calculations of sails with tilts

          - results look good for very small tilt values, but 
                 results for large angles have problems

          - we discover the problem: code was not yet including the
                 factor of cos(theta)*cos(theta) for photon pressure

          - code changed to do so

          - we discuss the issue of the sail coming too close to the Sun
                 and then the gravitational forces becoming unrealistic
  

  - goals for next meeting (Tue, Feb 28): 
   
          - insert code which stops the simulation if the distance of the
                 sail from the Sun becomes less than (2 * solar radius)

           - re-run tests of sail for 2 years, using tilt angles
                 of 0 to +90 degrees and 0 to -90 degrees

          - design a "near future" space probe
                 realistic probe mass for a camera and radio dish, etc.
                 realistic sail size
                 realistic sail material
                 compute total mass of sail + probe

          - we'll use this "near future" probe for future simulations

          - investigate the use of gnuplot
