DESCRIPTION:Materials Make Light Work – Or\, “Image is\nEverything”\nDr. Ma
 rk Andrews (Department of Chemistry\, McGill University).\nWhat do butterf
 ly wings\, Venus flower baskets and healthy doses\nof elements from the Pe
 riodic Table have to do with conveying\ndigital data\, music\, voice and v
 ideo by light? They can all be\ndesigned to make “light work”. Light is ra
 ther mysterious stuff\;\nbut Nature and scientists have found ways to make
  extraordinary\nmaterials in order to control light so that it can be used
  to\ntransmit information and render images. With animations\,\ndemonstrat
 ions and humour\, this talk begins by examining the\norigins of Canada’s o
 ptical internet as we forage among some early\nGreek\, Roman and Napoleoni
 c inventions. We then explore how species\nof aquatic micro-organisms and 
 sponges construct intricate “glass\nhouses” and woven optical fibre basket
 s\; and why butterflies and\nbeetles have such exquisite coloration. The f
 indings may teach us\nhow to make optical fibre and ultra-small optical ci
 rcuits from the\nconstituents of sea water\, biomolecules\, or patterns of
  solid and\nliquid crystals when combined with some fancy engineering. We
 \nconclude by describing how chemistry can be used to build optical\ncircu
 its on silicon chips to manage information flow like that from\niTunes® an
 d YouTube®. And if “image is everything”\, we point out\nways in which che
 mistry makes “light work” out of the revolution in\nimage-making: like the
  creation of an ultra-thin\, light weight\nplastic\, flexible liquid cryst
 al colour display\; and a programmable\nanimated poster made by printing w
 ith special inks that emit light.\nThroughout the talk\, concepts are pres
 ented together with examples\nin a simple manner to explain how materials 
 make light work.\nOrganized by McGill University and Science Outreach with
  the\nexpress purpose of fostering communication between scientists in\ndi
 fferent disciplines as well as between scientists and the\npublic.\nCuttin
 g Edge Lectures in Science are made\npossible through the generous support
  of Heather Munroe-Blum\n(McGill Principal)\, Richard Levin (Dean of Medic
 ine)\, Martin Grant\n(Dean of Science)\, Anthony Masi (Provost) and Denis 
 Thérien\n(Vice-Principal\, Research and International Relations). Lectures
 \nare followed by a vin d'honneur reception. Free\, everyone\nwelcome.\n
