Let Me Go
Submitted by Mehrdad Garousi on
This music video is a pure fractal animation made for Flinch, who is an electronic musician from North America. It is made in one of the well-known and still-under-evolution fractal programs Mandelbulb3D, except for minor post-render adjustments in Adobe Premiere. The animation is altogether a combination of 4 basic fractal formulas and what is seen during the 5:45 of the play is the result of variations in the constructing numeric variables defining these formulas or those controlling environmental phenomena like colors, lights, etc.
Crystals and Mathematics
Submitted by IMAGINARY on
Humans have been fascinated by crystals for a long time. Its regular geometry, its special symmetry, but also its diversity in colours surprise and please us. In this article, an overview of the connection between crystals and mathematics is given. It is a contribution to the International Year of Crystallography 2014.
Zero-dimensional symmetry
Submitted by IMAGINARY on
This snapshot is about zero-dimensional symmetry. Thanks to recent discoveries we now understand such symmetry better than previously imagined possible. While still far from complete, a picture of zero-dimensional symmetry is beginning to emerge.
Drugs, herbicides, and numerical simulation
Submitted by IMAGINARY on
The Colombian government sprays coca fields with herbicides in an effort to reduce drug production. Spray drifts at the Ecuador-Colombia border became an international issue. We developed a mathematical model for the herbicide aerial spray drift, enabling simulations of the phenomenon.
Operator theory and the singular value decomposition
Submitted by IMAGINARY on
This is a snapshot about operator theory and one of its fundamental tools: the singular value decomposition (SVD). The SVD breaks up linear transformations into simpler mappings, thus unveiling their geometric properties. This tool has become important in many areas of applied mathematics for its ability to organize information. We discuss the SVD in the concrete situation of linear transformations of the plane (such as rotations, reflections, etc.).
The Kadison-Singer problem
Submitted by IMAGINARY on
In quantum mechanics, unlike in classical mechanics, one cannot make precise predictions about how a system will behave. Instead, one is concerned with mere probabilities. Consequently, it is a very important task to determine the basic probabilities associated with a given system. In this snapshot we will present a recent uniqueness result concerning these probabilities.
Swallowtail on the shore
Submitted by IMAGINARY on
Platonic solids, Felix Klein, H. S. M. Coxeter and a flap of a swallowtail: The five Platonic solids tetrahedron, cube, octahedron, icosahedron and dodecahedron have always attracted much curiosity from mathematicians, not only for their sheer beauty but also because of their many symmetry properties. In this snapshot we will start from these symmetries, move on to groups, singularities, and finally find the connection between a tetrahedron and a “swallowtail”.
