A mother walks into her own bedroom and is surprised to catch her 10 year old daughter reading her diary. Startled, she just stands there.
"You were right mom," says the daughter. "Reading is fun."
Ewald HeringDied 26 Jan 1918 at age 83 (born 5 Aug 1834).Karl Ewald Konstantin Hering was a German physiologist and psychologist whose chief work concerned the physiology of colour perception. He taught at several universities. Hering challenged the colour-vision theory of Hermann von Helmholtz. Visual sensations, according to Hering's view, were due to three colour receptors responding in an “opponent” fashion in colour-pairs (white/black, yellow/blue, and red/green) to take account of the after-images of colours. Helmholtz had advocated the three fibre, three color theory (red, green and blue). Hering also is known for a classic optical illusion.[Image: Hering (inset) with his colour-blindness apparatus] |
