A very highenergy cosmic ray iron nucleus shoots into some photographic emulsion & collides with a silver or bromine nucleus in the emulsion to produce a tremendous jet of about 850 mesons. From the divergence of the jet, the total energy of the incoming iron nucleus is calculated to be more than 15,000 GeV an example of the enormous energy that can be carried by some cosmic rays. (The central dark core of the jet is about 0.04 mm across).

Abstract Art

Curious to try something new? Why not learn the language of colors? Our collection of abstract art will introduce you to intriguing concepts and emotions evoked by brushstrokes, shapes, and composition of art. A genre of modernism, abstract art, was founded by Wassily Kadinsky. It represents objects and ideas in an interpretive way.

Other famous abstract artists include Piet Mondrian, Joan Miro, and Jackson Pollock. See their work come alive with the painterly quality of our museum-grade canvas.
