Cube root can be done with a compass-and-straightedge construction. Newton's method is an iterative method that can be used to calculate the cube root. For real floating-point numbers this method reduces to the following iterative algorithm to produce successively better approximations of the cube root of "a": The method is simply averaging three factors chosen such that at each iteration. Halley's method improves upon this with an algorithm that converges more quickly with each step, albeit consuming more multiplication operations: With either method a poor initial approximation of "x" can give very poor algorithm performance, and coming up with a good initial
Gleaming the Cube to the cryptic question "Have you ever gleemed [sic] inside a cube?" that Garry Scott Davis (GSD) asked Neil Blender in an interview in the December 1983 issue of "Thrasher" magazine. In the film, Christian Slater's character defines "gleaming the cube" as "pushing your limits to the edge". The DVD contains an easter egg; by highlighting the skateboard on the main menu, viewers can watch a short featurette entitled "What Does Gleaming the Cube Mean?". Brian Kelly is an underachieving high school student in Orange County, California. An avid skateboarder, Brian is frequently at odds with his parents for his
