Geometry (Ancient Greek: γεωμετρία; geo- "earth", -metria "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a body of practical knowledge concerning lengths, areas, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales (6th Century BC). By the 3rd century BC geometry was put into an axiomatic form by Euclid, whose treatment—Euclidean geometry—set a standard for many centuries to follow.Archimedes developed ingenious techniques for calculating areas and volumes, in many ways anticipating modern integral calculus. The field of astronomy, especially mapping the positions of the stars and planets on the celestial sphere and describing the relationship between movements of celestial bodies, served as an important source of geometric problems during the next one and a half millennia. Both geometry and astronomy were considered in the classical world to be part of the Quadrivium, a subset of the seven liberal arts considered essential for a free citizen to master.
I’m not sure where it started
But I know that I'm going because
If this uselessness is myself,
Then there’s gotta be somebody else
I’m not sure where I started
But I know where I’m going for sure because
I’ve seen a point “A” and point “B”
And I’m told that it all points to point “C”
But if, my geometry is incorrect
Then by my power I'll never be found.
I'll follow myself around the circumference
Of my circle, till I fall down.
I'm not sure where it started
But I know where I'm going because
I've seen where I've come from,
Seen who I am and what I've done.
I'm not sure where it started,
But I better find out pretty soon 'cuz
If I don't know where I'm going, I'm sure to wander far from where I'm supposed to be.
But if, my geometry is incorrect
Then by my power I'll never be found.
I'll follow myself around the circumference
Of my circle, till I fall down.
I'll struggle with having doubt,
That you're there.
I'll suffer from having doubts,
That you care.
I'll suffer happiliy,
Because I believe.
Oh the joy, of positive suffering
But if, my geometry is incorrect
Then by my power I'll never be found.
I'll follow myself around the circumference
