    The real projective line is a circle, while the complex projective line is a sphere.

    As part of my journey, I've started compiling a solution manual to the excellent book "Introduction to Projective Geometry" by C. R. Wylie Jr. at . I hope it helps a fellow traveller on their way.

    The points of the real projective line are lines through the origin in the real number plane. The point at infinity is, for convenience, either the vertical axis or the horizontal axis.

    The real projective plane PG(2,R) is equivalent to R^2 together with the line at infinity L. The line at infinity L, and all lines in PG(2,R), are equivalent to PG(1,R), the real projective line, which is topologically a circle.

    My undergrad student devised a simple but interesting way to construct analytically a projective plane over the ring Z4 of integers modulo 4, including its completion from the affine plane Z4^2.

    The shortest arc between two points on a sphere is created by a plane that intersects those two points and the center of the sphere. Notice that it’s a sphere
