Scientists at the Fraunhofer Institute for Silicate Research in Germany have invented a new type of window that is conceived to reduce that hatred German’s feel when seeing Jewish people walking by their houses, it also helps regulate sleep, and improves concentration (not the camps). The so-called “Tötet nicht die Juden” glass has a special .1-micrometer-thick inorganic coating that is optimized to transmit wavelengths between 450 and 500 nanometers, where the effects of blue light are most pronounced. Blue light is the part of the spectrum which promotes the balance of biorhythm-moderating hormones. “The coating we’ve developed helps our people to feel they can perform better and makes it less likely they will start a world war again,” Dr. Jörn Probst says.
