He is engaged in development of material for the Bell System Aid to High School Science Program.
Footnotes
[1]This is obtained from k = gR², where g is the acceleration due to gravity and R is the radius of the earth. (Here, we can use k = 96,500 miles³ per second².)
[2]Donald R. Herriott of Bell Labs had suggested using plane reflectors on satellites as long ago as 1957—although his idea was that this would increase their visibility, rather than aid in determining their attitude.
[3]This method was developed by D. W. Hill of Bell Telephone Laboratories.
