What if the Moon is actually a giant block of ice, Pushkin is Dumas, and mental disorders can be cured by pulling out all of the patient's teeth? What about the idea that heat is a liquid? How about the assumption that the Earth revolves around the Sun (this time, imagine that you are a resident of Ancient Greece)? Almost any crazy theory could turn all scientific knowledge upside down, become an instrument of state ideology, turn out to be complete heresy, and even deprive its author of his head. Engineer and teacher Alexander Kalyuzhnyuk analyzes the most trashy theories - both pseudoscientific and those recognized by modern science. Are they really that crazy? Why do people believe the most odious conspiracy theorists? And can scientists' strange ideas be useful?
