ABSTRACT
Scientists have been successful in understanding and finding unifying principles. However, many people take the resulting technology for granted and do not understand the limitations of humans as part of the physical world. There are moral laws (or principles), civil laws, and physical laws. Moral laws have been broken (e.g., murder and adultery), civil laws have been broken (almost everybody has driven over the speed limit), but no one breaks a physical law. Therefore, we can only work with nature, and we cannot do anything that violates the physical world.
