A little mystery is good in life...keeps you thinking in the still of the night. Makes you want to get up in the morning, have a strong cup of coffee, and go after an explanation. Sometimes one sits in front of you for a while and nobody pays attention to it. It's not graphite grains. Is it two photon absorption by hydrogen molecules?
