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.

Hubble Views The Final Frontier For Dark Matter
“This phenomenon of gravitational lensing stretches galaxies into streaks and arcs, magnifying them, and creating multiple images. It also enables us to reconstruct the mass distribution of the cluster, revealing that it’s mostly due to dark matter.”
When you look out at the distant Universe, you can see all sorts of things: stars, galaxies, clusters of galaxies, going as far back into the distant past as our telescopes can image. But where you have the greatest concentrations of mass, an extreme phenomenon emerges: that of gravitational lensing. Any foreground objects lying behind that mass will have their light stretched, magnified and distorted by the intervening matter. Recently, as part of the Hubble Frontier Fields program, the telescope followed-up on galaxy cluster Abell 370, and revealed the most spectacular gravitational lensing signal ever seen in a galaxy cluster. Most importantly, it provides some very strong evidence not only for dark matter’s existence, but for its presence distinct from any galaxies at all.

Fluorite and Baryte
Locality: Berbes, Asturias, Spain
The laws of thermodynamics are some of the most important principles in modern physics, because they define how three fundamental physical quantities - temperature, energy, and entropy - behave under various circumstances.
But now physicists say they’ve found a loophole in one of these laws, and it could create scenarios in which entropy - or disorder - actually decreases with time.
