The speed of light in a material | Matter & Interactions - 0 views

  •  
    this is an great post that explains that the speed of light doesn't slow down in materials, nor are charges inside a conductor "shielded" from external electric fields by the surface charges on a conductor.

The Milky Way and Storms over Africa - 0 views

  •  
    This video was taken by the crew of Expedition 30 on board the International Space Station. The sequence of shots was taken December 29, 2011 from 20:55:05 to 21:14:09 GMT, on a pass from over central Africa, near southeast Niger, to the South Indian Ocean, southeast of Madagascar. The complete pass is over southern Africa to the ocean, focusing on the lightning flashes from local storms and the Milky Way rising over the horizon. The Milky Way can be spotted as a hazy band of white light at the beginning of the video. The pass continues southeast toward the Mozambique Channel and Madagascar. The Lovejoy Comet can be seen very faintly near the Milky Way. The pass ends as the sun is rising over the dark ocean.

Systematic Wonder: A Definition of Science That Accounts for Whimsy | Brain Pickings - 0 views

  • Science is an inherent contradiction — systematic wonder — applied to the natural world. In its mundane form, the methodical instinct prevails and the result, an orderly procession of papers, advances the perimeter of knowledge, step by laborious step. Great scientific minds partake of that daily discipline and can also suspend it, yielding to the sheer love of allowing the mental engine to spin free. And then Einstein imagines himself riding a light beam, Kekule formulates the structure of benzene in a dream, and Fleming’s eye travels past the annoying mold on his glassware to the clear ring surrounding it — a lucid halo in a dish otherwise opaque with bacteria — and penicillin is born. Who knows how many scientific revolutions have been missed because their potential inaugurators disregarded the whimsical, the incidental, the inconvenient inside the laboratory?”
