a: Differential geometry ~
b: a fabulous city standing at the confluence of two rivers
What: "Differential geometry is like a fabulous city standing at the confluence of two rivers, drawing upon the riches of both river systems. Only differential geometry stands at the confluence of three streams of mathematics; analysis, geometry and algebra."..... See the rest in the linked page..... The analogy gets mixed up from 2 to 3; That is 2 streams become 3.
