Stretching SpaceTime

According to general relativity, the sun’s mass makes an imprint on the fabric of spacetime that keeps the planets in orbit. A neutron star leaves a greater mark. But a black hole is so dense that it creates a pit deep enough to prevent light from escaping.

Galaxy Cluster Abell 1689

This image shows the galaxy cluster Abell 1689, with the mass distribution of the dark matter in the gravitational lens overlaid (in purple). The mass in this lens is made up partly of normal (baryonic) matter and partly of dark matter. Distorted galaxies are clearly visible around the edges of the gravitational lens. The appearance of these distorted galaxies depends on the distribution of matter in the lens and on the relative geometry of the lens and the distant galaxies, as well as on the effect of dark energy on the geometry of the Universe.

Adjustable Wood Lamp ‘Goldberg’

The adjustable ‘Goldberg’ lamp by Atelier Akerboom is a handmade wooden lamp. By adjusting the 31 openings of the lamp you can control how much light it gives out in any direction. The lamp can be used as a hanging (pendant) lamp or as table or floor lamp. The lamp is available in different colors (see information sheet) and in two sizes (30cm or 50cm diameter).

This special design is named after Michael Goldberg (1902-1990) who described the Goldberg polyhedron – a convex polyhedron made from hexagons and pentagons – first in 1937.

“Sketching Fractals” by Music: Fractals are a treat for your eyes, but what about your ears?

Fractals are geometric constructs that exhibit similar or identical characteristics at every level of magnitude. They provide new tools for geometers to describe objects of extreme intricacy, such as clouds, ferns, snowflakes, mountain ranges, stock-market fluctuations, the human circulatory and nervous system, etc.. The geometry of Fractals brings us a new appreciation for the natural world and the beauty of mathematics. Some of the most popular examples are: The Sierpinski triangle  and the Von Koch snowflake.

Fractals are a treat for your eyes, but what about your ears?. Dmitry Kormann, a composer/keyboardist from São Paulo, Brazil, explains how he brings fractal-like patterns to the very structure of his music, to obtain beautiful results. See more at:  [http://plus.maths.org/issue55/features/Kormann]
