I was wondering about how great the differences are ...
Most of the people on the planet live engrossed in the occurences of their daily lives. Without giving much thought to abstract issues.
Then we have other people who devote their lives to the same abstract issues. I have particularly great respect for scientists/physicists. Where would humanity be, or rather how poor would humanity be without the contributions of Albert Einstein, Niels Bohr, Werner Heisenberg, Richard Feynman, Carl Sagan, and so many others like these.
There are great scientists in the biological sciences who have found cures for diseases and contributed so much to our understanding about our own selves.
Great scientists in the various physical sciences who have helped invent so many of the tools that have helped improve the quality of our lives.
And we take all of these things for granted ...
And continue to live in our tiny, little rat-holes.
It's like much of humanity is like parasites that lives off of the greatness of a few human beings.
Let's hope the supply of geniuses does not dry up any time soon as humanity has got limitless potential if only we are willing to raise our eyes upwards and think about the endless possibilities.
