What is most magnificent about human invention is how we open for ourselves new conceptions of reality previously unimaginable.

–—Rabbi Menachem Mendel Schneerson,
Likutei Sichos vol. 15, pp. 42–48

The most beautiful emotion we can experience is the mystical. It is the power of all true art and science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead. To know that what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull faculties can comprehend only in their most primitive forms—this knowledge, this feeling, is at the center of true ­religiousness. In this sense, and in this sense only, I belong to the rank of devoutly religious men.

—Albert Einstein, as quoted in Philip Frank, Einstein:
His Life and Times (1947)

Every system is perfectly designed to get the results it gets.

—W. Edwards Deming

Learning is not compulsory but neither is survival.
