Type of Spiritual Experience
Charles Francis Richter was an American seismologist and physicist. Richter is most famous as the creator of the Richter magnitude scale which, until the development of the moment magnitude scale in 1979, quantified the size of earthquakes. Inspired by Kiyoo Wadati's 1928 paper on shallow and deep earthquakes, Richter first used the scale in 1935 after developing it in collaboration with Beno Gutenberg; both worked at California Institute of Technology.
A description of the experience
Every man has two educations – that which is given to him, and the other, that which he gives to himself. Of the two kinds, the latter is by far the most valuable. Indeed all that is most worthy in a man, he must work out and conquer for himself. It is that, that constitutes our real and best nourishment. What we are merely taught, seldom nourishes the mind like that which we teach ourselves.
