Andri Pol takes a look inside CERN’s Swiss headquarters
Since being established in 1952, CERN (european organization for nuclear research) has been an internationally recognized center charged with the considerable task of exploring and understanding the fundamental structure of our universe. located near Geneva, close to the Franco-Swiss border, a team of over 2,500 physicists, engineers and researchers utilize some of the most complex and vast instruments on earth, studying the particles of matter which make up the world around us. the 2,512 members of on-site staff include 1,021 engineers and scientists, 883 technicians, 397 administrators and office staff, 132 craftspeople and 79 research physicists.
From Astronomy Picture Of The Day; June 5, 2013:
Except for the rings of Saturn, the Ring Nebula (M57) is probably the most famous celestial band. Its classic appearance is understood to be due to our own perspective, though. The recent mapping of the expanding nebula’s 3-D structure, based in part on this clear Hubble image, indicates that the nebula is a relatively dense, donut-like ring wrapped around the middle of a football-shaped cloud of glowing gas. The view from planet Earth looks down the long axis of the football, face-on to the ring. Of course, in this well-studied example of a planetary nebula, the glowing material does not come from planets. Instead, the gaseous shroud represents outer layers expelled from the dying, once sun-like star, now a tiny pinprick of light seen at the nebula’s center. Intense ultraviolet light from the hot central star ionizes atoms in the gas. In the picture, the blue color in the center is ionized helium, the cyan color of the inner ring is the glow of hydrogen and oxygen, and the reddish color of the outer ring is from nitrogen and sulfur. The Ring Nebula is about one light-year across and 2,000 light-years away.
Who is your favorite physicist?
Albert Einstein signature
Well, listen as Albert Einstein reads you a scientific essay. It’s his voice, in your ears, from 1941, reading his essay ‘The Common Language of Science’.
