Ho boy, jimp, you are a piece of work. Your jealousy is obvious, your language inappropriate, and your absolute contempt and total disgust are addressed in these Anger Management classes. You, jimp, need these services: > http://www.yellowpages.com/rancho-cucamonga-ca/anger-management-classes Physicists experimentally realize a quantum Hilbert hotel > http://phys.org/news/2015-10-physicists-experimentally-quantum-hilbert-hotel.html > (Phys.org)—In 1924, the mathematician David Hilbert described a hotel > with an infinite number of rooms that are all occupied.
