“Sketching Fractals” by Music: Fractals are a treat for your eyes, but what about your ears?

Fractals are geometric constructs that exhibit similar or identical characteristics at every level of magnitude. They provide new tools for geometers to describe objects of extreme intricacy, such as clouds, ferns, snowflakes, mountain ranges, stock-market fluctuations, the human circulatory and nervous system, etc.. The geometry of Fractals brings us a new appreciation for the natural world and the beauty of mathematics. Some of the most popular examples are: The Sierpinski triangle  and the Von Koch snowflake.

Fractals are a treat for your eyes, but what about your ears?. Dmitry Kormann, a composer/keyboardist from São Paulo, Brazil, explains how he brings fractal-like patterns to the very structure of his music, to obtain beautiful results. See more at:  [http://plus.maths.org/issue55/features/Kormann]

closely related to sharks but with long, flat bodies and wing-like pectoral fins, mobula rays are ideally suited to swooping through the water - here off the gulf of california - yet seem equally at home in the air, so much so that they have earned the name “flying rays”. mobula rays can reach heights of more than two metres, remaining airborne for several seconds. 

mobula rays are quite elusive and difficult to study, so biologists are not quite sure why they jump out of the water. theories vary from a means of communication, to a mating ritual (though both males and females jump), or as a way to shed themselves of parasites. they could also be jumping as a way of better corralling their pray, as seen with them swimming in a circular formation. 

what is known about mobula rays is that they reach sexual maturity late and their investment in their offspring is more akin to mammals than other fishes, usually producing just a single pup after long pregnancies, all of which makes them extremely vulnerable to commercial fishing, especially as a species that likes to come together in large groups.
