    how about instead of just making a joke about seizures, you actually warn people before flashing the screen

    I have a question, if humans were to drill a hole from one side of the earth to the other side (ignoring the core and danger) would you be flipped upside down and defy gravity or would you just slowly be standing on the ground?

    Why do we see that with the naked eye with car rims if they are going a certain speed? Does the sun have a continuous flicker ("shutter speed")... or does our eye? What's the go?

    Since we’re being pedants: “the reason is because” is redundant. MW says it’s acceptable, but they can go fly a -kite- helicopter.

    You must determine where you are going in your life, because you cannot get there unless you move in that direction. Random wandering will not move you forward. It will instead disappoint and frustrate you and make you anxious and unhappy and hard to get along with (and then resentful, and then vengeful, and then worse).
    Family love is so big and immense, and sometimes we do not know what we have till we lose it. There is a proverb which says: when you haven t what you like, you should like what you have

    Why do you sometimes see this kind of effect on car wheels if they're driving at just the right speed? What's the frame rate of my eyeballs?

    • Deipatrous
      Deipatrous Day ago

      You mean... IRL??? Human perception ceases to distinguish individual images round about 12 per second, but it depends on attentiveness and complexity of the field of vision. Rods and Cones are continually being fired, so in that sense there is no rate limitation, but each of them takes a few hundred milliseconds to get back to a triggarable state.16 fps looks perfectly fluid under most circumstances. I don't understand people who discern a difference between 25 and 50 fps. They sound like the audiophiles of old, pretending to hear differences that are not apparent to the uninitiated.

    Did this at a party in college. Had black lights and glow stickers on the end of the fan blades but set a strobe light to match fan speed to make the blades look stationary. The glow stickers though formed a greenish halo around the fan. It was a cool effect - until people who had a few drinks tried to touch it, were surprised it hurt to touch, and would try to touch it again.
    I also enjoy car wheels that spin so fast they look like they are spinning backwards slowly.

    Your brain has a frame rate. Watch wheel rims on a car as they accellerate or decelerate. They'll appear to slow down, then reverse direction. If they could maintain the exact speed where the apparent direction changes, they would appear frozen. After all, in order for it to reverse direction, even apparently, it has to come to a full stop.

      To be fair, tho, he did say he was demonstrating a strobe light technique. Someone prone to seizures should know that a strobe light is prone to cause seizures.
      but yes. a warning would've been nice.

    I used to have a wooden helicopter back like 2005 and would spin the blades as fast as I could in front of our living room TV.
    Let me tell you how shocked 5 year old me was when it looked like they were starting to spin in reverse.

    I like the style of this video, it was sort of a debunking video, but also sort of a "how it was done" video like you've been doing lately; hopefully we see more like this in the future. 👍
    Also, that ending was a real smash ;p
