Question:
I am interested in calculating the distance from the earth to the sun. In
the past, I heard of a way to do this by measuring the sun's shadow at
various times and at two different locations. Is this true? I do not know
all the details, so if you can supply the details or refer me to a reference
in which I can have my class calculate the distance, I would appreciate it.
The class that I teach is pre-calculus, so the students know trigonometry.

Replies:
A good and widely available reference is MATHEMATICAL METHODS IN SCIENCE by
George Polya. The publisher is The Mathematical Association of America and
this is Volume 26. in a long series of books designed to provide material
for secondary students on topics not usually seen in high school syllabi.
Section 2 on "Astronomical Measurements".
