This video stream shows live images of particles as they zip through a cloud chamber which is set up in the public Microcosm exhibition at CERN. Different shapes of clouds are formed depending on the particle type, energy and direction. The clouds are the result of particles interacting with the vapour inside the chamber. Most particle tracks are caused by natural radioactivity (present in the soil and air) and particle showers originating from the Earth's atmosphere. These showers are created by cosmic particles hitting the Earth's atmosphere, which transforms them into myriads of lower-energy particles like pions, muons and electrons. This live stream is available during the opening hours of the Microcosm exhibition at CERN. In general, the stream should be running from Monday to Saturday, 8:30 - 20:00 (Swiss time).

It is hard to represent our spherical world on flat piece of paper. Cartographers use something called a "projection" to morph the globe into 2D map. The most popular of these is the Mercator projection.

Every map projection introduces distortion, and each has its own set of problems. One of the most common criticisms of the Mercator map is that it exaggerates the size of countries nearer the poles (US, Russia, Europe), while downplaying the size of those near the equator (the African Continent). On the Mercator projection Greenland appears to be roughly the same size as Africa. In reality, Greenland is 0.8 million sq. miles and Africa is 11.6 million sq. miles, nearly 14 and a half times larger.
