When I was born in 1895, reality was everything you could see, smell, touch and hear. The world was thought to be absolutely self-evident. When I was three years old, the electron was discovered. That was the first invisible. It didn't get in any of the newspapers; (nobody thought that would be important!) Today 99.99 percent of everything that affects our lives cannot be detected by human senses. We live in a world of invisibles. The fact that humanity does not understand nature is the prime reason for humanity's failure to exercise its option to attain universally sustainable physical success on this planet I am confident that humanity's survival depends on all our willingness to comprehend feelingly the way nature works."
