Many of you will probably have heard about quantum mechanics, and that it supposedly supports spirituality and mysticism, through films like “What the Bleep do we know” or Fritjof Capra's book “The Tao of Physics”. I should warn you however that not all physicists agree with all of this, so you should be careful not to make uninformed claims about what quantum mechanics supposedly says, so as not to alienate those physicists further. I have for example heard spiritual people claiming things like “Quantum mechanics says that everything is possible.” It sounds grand and spiritual but is not true.
