AutoRicerca is a journal whose mission is to publish writings of value on the topic of inner research (but not only). This nineteenth issue of AutoRicerca is entirely dedicated to the topic of quantum physics, with three essays by Massimiliano Sassoli de Bianchi. The first is an updated and expanded edition of a booklet that the author published in 2013, entitled "Observer Effect". The second is the "transliteration" of a video that the author published in 2012, on the subject of the Heisenberg's uncertainty principle and quantum non-spatiality. Finally, the third is a short article in which the possibility of spontaneous self-teleportation of a human body is explored.
