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
The Cube (restaurant) The Cube (restaurant) The Cube is a pop-up restaurant created by Electrolux. Since 2011, two versions of the restaurant have been located in different cities in Europe, where a number of guest celebrity chefs have brought teams and dishes from their own restaurants to cook in the spaces. The Cube was designed by Park Associati design studio in Milan, and the construction covers a space of 140 m. It has an outside balcony allowing for a 360-degree field of vision. The exterior shell is made of aluminium and has hexagonal shapes cut into the shell by laser in order to
