In today's psychology class we were discussing about the senses' minimum perception threshold (i.e. the minimum level of intestity of a stimulus for it to be detected by the body's sense organs).
Well, the teacher was making examples to make the thing clearer, and so we ended up with sight and, according to her, the human eye is sensible, at night, with clear sky, to a CANDLE 31 MILES (50 KM) AWAY! I couldn't believe it, so asked her to confirm the numbers again, and she did confirm it was 31 Miles! To my knowledge, the eye's sensibility to a candle is something well under 330ft (100 m, more or less).
One thing's sure, she's no flashaholic... /ubbthreads/images/graemlins/rolleyes.gif
