Cool fact! Do you want to ask each other trivia questions, or just trade neat, potentially obscure facts we know?

Ok! Did you know that pink is not a color, in terms of the visible spectrum of light? Our brain generates pink as result of reflected light from pigments that it can't interpret very well. I think it happens when red cones in the eye fully fire, and green and blue cones only partially do......but, really, all color is just a brain construct.

as spock mighta said, "fascinating..."

2-speaker stereo sound is an illusion of full-bodied sound between and around two speakers separated by roughly 60 degrees in an equilateral triangle with the listener completing the triangle. the word stereo comes from the greek for "solid."

Ooh! 60 degrees is also the averages person's field of vision. Outside that is the peripheral, then the blind areas. The theory of perspective used for drawing is based on the 60 degree field, but cool effects like fish- eye and other distortions can be achieved by adjusting it.

pulse code modulation was invented in 1937 by british inventor alec reeves, and was for decades used for telecommunications before somebody at IBM thought of using it, in the early 60s, for audio.

Hmm. interesting. Early Daguerreotypes (tin type photographs) had long exposure times, of a minute or more. That meant they could not capture anything in motion, even blinking eyes. If a subject moved even a bit, that person, or part of them, might not appear on the film. Busy streets look empty in Daguerreotypes. Photographers developed complex metal supports for sitters to lean against which helped hold the head and support the back. People stared straight ahead, or to the side, to focus without blinking. Besides poor dental health, long exposure times were another reason people did not usually smile.

Photography advanced rapidly after Daguerreotypes, though. By the Civil War in the US, people could show the whole gamut of emotions in photographs.

May I have a cherry grenadine, please, Bartender?

Narcissism is an Achilles Heel.

How is wanting a Cherry Grenadine Narcissistic?

I meant in photos. I was thinking of selfies. NOT you!

many professional musicians have some degree of high-frequency hearing loss.

I don't believe "selfie" was even a word until about 2012 or so.

And to think: For the first 36 years of my life, I had no Internet!

Yay more people in the bar!! Wow. Words I never thought I would say. You are correct, kraftie. Also for a brief moment civil war photography robbed war of its romance and sense of being a grand adventure which would help mold boys into men. Matthew Brady's battle field aftermath photos shocked the nation, who had been lead to believe that soldiers killed in battle died quickly, painlessly, and heroically with lots of glory. I am told it is still the practice of surviving war buddies to tell grieving families this, even today! Exposure times were still too long to capture actual battles, but the bodies and the devastation were meticulously recorded.

I will happily make your cherry grenadine, I have never tried one, so I will pour two.

^^^mebbe a third cherry grenadine?
