"Earth Plane," is a translation of Eric Deubay's book "The Earth Plane." This book is intended for children and it easily proves strictly scientific truths without using terrible mathematical formulas. For those who have forgotten astronomy, optics, physics and geometry, it will also become a reliable and fun help in getting rid of pseudoscientific dogmas that have become boring. Only 44 pages and in front of readers will open unobservable horizons of truth for further self-education.
