For millennia, astronomers joined pairs of stars and called the result a line.
This instrument asks the next question:
When any three stars are joined, what figure is formed?
Method. The dome above shows the true sky over your site, at this
very hour. Select any three stars. The instrument draws the figure, measures it,
and classifies it with full rigor.
Standing result. Every figure examined to date has been a triangle.
The Survey continues.
