Cube root solution expressions involve the real cube root of a real number, while if all three solutions are real numbers then they may be expressed in terms of the complex cube root of a complex number. Quartic equations can also be solved in terms of cube roots and square roots. The calculation of cube roots can be to traced back to Babylonian mathematicians from as early as 1800 BCE. In the fourth century BCE Plato posed the problem of doubling the cube, which required a compass-and-straightedge construction of the edge of a cube with twice the volume of a given cube;
Curiosity: What's Inside the Cube? You're not just doing things in the cube. You don't realise it but you're doing something in something else as well at the same time." Peter Molyneux claimed that "what is inside the cube is life-changingly amazing by any definition". Critics stated that the game designer might be over-promising. When it was suggested to him that he should "tone down the enthusiasm", he responded: "I don’t want to believe less in something. I want to make something that is worthy of the emotion behind it." "Curiosity" was one of the few games that could be successfully played by a simple
