This crop shows the detail of an inner edge of the main ring in Derbyshire's image. It is a favorite of John Baez, a mathematical physicist at the University of California, Riverside, who posted these images on his Web site .....[ More ]

Around the number 4/5, a white line again traces the real axis—Derbyshire's polynomials have a seemingly continuous collection of real roots in the vicinity. But above and below the axis, the imaginary numbers form intricate flame-like patterns.....[ More ]

This crop of Derbyshire's image shows intriguing patterns around the imaginary number i, the square root of –1.....[ More ]

Derbyshire's image of 24th-degree polynomial roots with coefficients of either 1 or –1 features a serrated hole around the root 1. The white line slicing through the image traces the horizontal (or real) axis—the line comprises the real roots of the polynomials.....[ More ]

Sam Derbyshire, an undergraduate student at the University of Warwick in England, took a large but very specific set of polynomials to make this rich plot, comprising hundreds of millions of individual roots.....[ More ]

This crop of the previous slide reveals details of the hole near i on the vertical (imaginary) axis, which appears at the top center of the image and in greater detail in the inset. (The different colors of the points represent roots of polynomials of different degrees.) Note that i appears as a polynomial root but its closest neighbors do not.....[ More ]

Dan Christensen, a mathematician at the University of Western Ontario, plotted the roots of polynomials of degree six or less whose coefficients are integers between –4 and 4. The collection has large holes surrounding the points 0, 1 and –1 on the real axis—although some polynomials have those numbers as roots, the numbers nearby (especially those incorporating an imaginary component) seem to be off-limits.....[ More ]
