quade 3 #26 August 29, 2004 Quote i've been told that 1/20th of a sec (.05) was the limit of human perception. Depends on what you're talking about. I can -definately- see the flashing of a screen refresh, 1/60th or so, using my peripheral vision. I also see flourecent tubes flashing in the same way. This is actually not uncommon. I do not see the same effect with the fovea, the center on my vision. That said, it's possible to "see" something as brief as a millionth of a second. A flash going off in a room for instance. However, persistance of vision would make it difficult to distinguish between two flashes closer than about 1/20th.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites

I do not see the same effect with the fovea, the center on my vision. 24 frames a second is an old standard for motion picture films. It's not the maximum of what a person can detect, but rather the minimum sufficient rate to consistently trick a brain into seeing motion. A good way to experience this yourself is to rig up some contemporary video games that can show you the frame rate real-time. You can really see and appreciate the difference between 20 and 60 frames / sec. And I think you'll find that anything less than 20 seems choppy. ISTR broadcast television uses 30 frames / sec...tho watching my mom's satellite dish it's apparent to me that satellite & cable cheat a bit. nathanielMy advice is to do what your parents did; get a job, sir.

kelpdiver 2 #32 August 30, 2004 With a couple false starts, I managed to get it to register an absolute zero on trial 2. Trial 5 was an honest ,125. The other 3 were .203, .203, .218. Claimed average thus .1498. Second run I averaged .177 with a slow .234 and an honest .078. If I'm up later tonight on this, you'll be getting a visit from my goons.

quade 3 #34 August 30, 2004 Quote ISTR broadcast television uses 30 frames / sec...tho watching my mom's satellite dish it's apparent to me that satellite & cable cheat a bit. NTSC television is 29.97 "frames" per second with each frame made of two screen refreshes called "fields", so the screen flashes about 60 times per second. Each field in the frame can (usually does) have unique information so it would not be out of line to think of it as 60 frames per second at half verticle resolution. BTW, before the invention of sound, the standard frame rate was 18 frames per second -- more or less, nothing was very well calibrated -- which is why when old silent movies are shown everyone appears to move so quickly. Most were simply ran through the telecine at the now standard film rate of 24 fps.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites

quade 3 #41 August 30, 2004 Quote Quade, who invented sound? When? Synchronized sound film, but I gather you already surmised as much. Edison usually gets the credit, but like a lot of his inventions, there is quite a bit of discussion on that point.

Probably nothing, but it does have some implications if you consider how fast we might need to react to things, variations in reaction times with age and sex as pointed out in http://biae.clemson.edu/bpc/bp/Lab/110/reaction.htm. Certain aspects of the sport might be considered a "young man's game" with the turning point somewhere around mid to late 40s.
