Just some thought about how much information we may not observe due to the sampling rate of our senses.

  • I wonder how much the flicker rate can vary.

    I'm pretty sure my flicker rate improved over the years and I started to see things "flicker" that shouldn't flicker at all.

    Is there any software to test this?

  • Not sure Nopiw. I reckon there would be some software. It may vary at different time though. Like when you are tired or after you had 3 cups of coffee. I'd be interested to know if you find something.

  • I found a method to test the flicker rate.. a LED on a wave generator.

    I don't have a wavegen at the moment, but I can either use my soundcard or build a small astable trigger circuit. we'll see

    Funny thing is my flicker rate depends on color (I think). If I watch TV (50Hz, Europe) I can clearly see the white areas as alternating black and white, while a green area right next to it is just green. My friends and family say, they can't see the it... I couldn't see it either some years ago.

  • Colour is related to frequency so you could be onto something there. In fact, I just read the abstract by a study that said exactly that. Apparently the brightness also effects it. I couldn't find an online test which would be nice.

  • Excellent. This is one of my rants. Nice presentation!

    Happy Easter, Gadz.

  • You too buddy.

  • this is really interesting you're awesome

  • FUCK I'M HIGH. Good stuff man!

  • nice findings thanks for the info 5 stars

  • I like your way of looking at things, I like aussies too.

    fairdingcom mate :)

    Do I spell it right ? :))

    I had a lot of fun with aussies sking at Whistler a long time ago. Don't know why there is something in common between you and us... Colonialism ? Christianism ? Maybe wre just Zionist targets ? lolll

    I wanted to say that if I remember wright the neurons respond at roughly 1-2 KHz but the DELAY is used to make us ear sounds at 15-18 KHz.

    See the single electron interference

  • Light is around 1000 GigaHz. Receptros of different colors are just AM at different frequencies or colors.

  • yes but there is no way a neurone could even know the frequency, it's just that the wavelenght is of the proprer energy to trigger the sensor which is very very much slower then a neural circuit.

    We react to the amplitude modulation in fact, which can be too fast for us anyway.

    Just to say that their is a carrier frequency, like AM radio at 800 kilohertz carries voice from 30 Hz to somthing like 10 or 20 KHz.

  • PS: I rarely drink coffee or things containing caffeine. Just water and orange juice ;)
