Who's For Pi?

As all mathematicians will know, March 14th is Pi Day! It is held on March 14th as this date can be represented at 3/14. 3.14 are the first three digits of Pi, which is represented by the Greek letter π. Pi is the ratio of the circumference of a circle to its diameter.


In celebration, I thought I would highlight this Geometry book [L.0001], which was handwritten and drawn by Master R. Green whilst he attended Messrs. Graham & Son’s Academy. 

Frontispiece of R. Green, Geometry 

He explains the basic shapes associated with the subject before working his way through a series of geometrical problems and their solutions.  Starting with the simple ‘How to divide a given line AB into two equal parts’ right up to ‘How to find the convex surface of the frustrum of a Right Cone’.

The book is a treat for the eyes even though the subject matter is, for the most part, beyond my comprehension!
