The next event of the "Kultur im MiMa" series will be on the 27th of July 2011. Prof. Stephan Klaus will give a presentation on "Symmetry and Beauty in Nature and Mathematics". Many objects in nature feature regularities that we appreciate as beautiful. Just think of snow flakes, snail shells or crystals. And also in art beauty is connected to regularity, for example at the Arabesques of the Alhambra. But, can a mathematical formula be beautiful? Venue: MiMa, Admission: 18.00 hs, Entry: 5 Euro / 3 Euro. More information in the flyer.

How do we gain mineral resources? How does a mine work? How do I know which forms are connected to which formulas? How do soap bubbles relate to the fourth dimension? Answers and more questions can be found at the MiMa stall, on all three days from 9 am to 5 pm.
