The measurement of distance

The Measurement of Distance

  • Triangulation: Measure baseline and angles, can calculate distance


The measurement of distance1

The Measurement of Distance

Parallax: Similar to triangulation, but look at apparent motion of object against distant background from two vantage points


Measuring distances

Measuring Earth’sradius:

Done by Eratosthenes about 2300 years ago; noticed that when Sun was directly overhead in one city,it was at an angle in another.

Measuring that angle and the distance between the cities gives the radius.
