Though they are not just a recent phenomenon, during the past few decades new crop circles have been reported worldwide at the rate of about one per day, creating considerable controversy over their origin and cause. Theoretical experimental physicist Eltjo Haselhoff presents a comprehensive overview of these beautiful and mysterious formations. His research includes a scientific investigation of germination anomalies, the dead fly enigma, peculiar deposits, geometrical ratios, and balls of light. In addition, he reports on the first-person accounts of people who have witnessed their appearance and even ventures into the study of the psychic perspective. Haselhoff comes to some fascinating conclusions in the last chapter, 'Circular Arguments.' After reading this book, you will definitely agree with Conclusion Six: 'Something very strange going on.'
