continuum.quest

The continuum is not a concept to be explained but a terrain to be traversed. Below this line, the surface unfolds into finer and finer resolution -- an infinite descent through scales of being, each containing more than the one above it. Scroll to enter.

the interval

Between zero and one lies an infinity larger than all the whole numbers that have ever been or will ever be counted. Georg Cantor proved this in 1874 and it shattered the foundations of mathematics. The continuum is not merely infinite -- it is transfinitely so, a higher order of boundlessness that no enumeration can exhaust.

Take any two points. Name the midpoint between them. Now take either half and name its midpoint. Repeat. You will never run out of midpoints. You will never reach the bottom. The interval is bottomless.

the density

Between any two rational numbers there exists an irrational number. Between any two irrationals there exists a rational. The rationals and irrationals are everywhere dense in the reals -- they interpenetrate so thoroughly that neither can be separated from the other. This entanglement is the texture of the continuum.

the limit

Convergence is the promise that infinite processes can have finite destinations. The series 1/2 + 1/4 + 1/8 + ... approaches 1 but is never 1. And yet the limit IS 1. The destination exists even though the journey never arrives.

the infinitesimal

Smaller than any positive number. Greater than zero. A ghost quantity that Leibniz dreamed and Robinson proved.

Everything. Here.
