Animation depicting evolution of a Cornu spiral with the tangential circle with the same radius of curvature as its tip ( click on thumbnail to observe ).
By solving Apollonius'problem repeatedly to find the inscribed circle, the interstices between mutually tangential circles can be filled arbitrarily finely, forming an Apollonian gasket, also known as a " Leibniz packing " or an " Apollonian packing ".
Other geometric results by Steiner include development of a formula for the partitioning of space by planes ( the maximal number of parts created by n planes ), several theorems about the famous Steiner's chain of tangential circles, and a proof of the isoperimetric theorem ( later a flaw was found in the proof, but was corrected by Weierstrass ).
Uniformization by parallel slit domains holds for arbitrary connected open domains in "'C "'; conjectured ( Koebe's " Kreisnormierungsproblem " ) that a similar statement was true for uniformization by circular domains . proved Koebe's conjecture when the number of boundary components is countable; although proved for wide classes of domains, the conjecture remains open when the number of boundary components is uncountable . also considered the limiting case of osculating or tangential circles which has continued to be actively studied in the theory of circle packing.
