INSPIRATION
"The most beautiful experience we can have is the mysterious. It is the fundamental emotion which stands at the cradle of true art
and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are
dimmed." (Quoted from Einstein, Reprinted Leach 1930)
