    • Invisibility: Theory & Practice - Balticon, May 25th 2013 http://timeandquantummechanics.comThe InvisibleMan“If a sheet of glass is smashed, Kemp, and beaten into a powder, itbecomes much more visible while it is in the air; it becomes at last anopaque white powder. This is because the powdering multiplies thesurfaces of the glass at which refraction and reflection occur. In thesheet of glass there are only two surfaces; in the powder the light isreflected or refracted by each grain it passes through, and very littlegets right through the powder. But if the white powdered glass is putinto water, it forthwith vanishes. The powdered glass and water havemuch the same refractive index; that is, the light undergoes very littlerefraction or reflection in passing from one to the other.” -- Griffin…"Yes, yes," said Kemp. "But a mans notpowdered glass!"Monday, June 3, 13

    • Invisibility: Theory & Practice - Balticon, May 25th 2013 http://timeandquantummechanics.comCamouflageModern camouflage began in1915, when, after a crushingdefeat by the Germans, theFrench army abandoned theirstylish white gloves and redpantaloons and enlisted a cadreof artists to develop stealthierattire. The U.S. followed suit in1917. In addition to hand-painted uniforms, thesecamoufleurs created falsebridges, decoy tanks, and, asseen above, paper-mache horsecarcasses that snipers used asblinds.Monday, June 3, 13
