        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.

                  Thanks for the huge laugh about the "licensing requests" of this loser. I'm going to spam the hell out of his e-mail address regarding this.

                    Car ads use this to show off the tires or the rims while the car is driving

                        Can you check this video? Not able to explain what’s going on. I believe it might be a fluid dynamics thing.

                                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

                                                          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.
