The Strobe Light Conundrum

The post - Illusion of Perception obviously confused a lot of people since I have been getting a lot of requests to explain it again.

Let me try it again with another animation.

The setup

The illusion of falling droplets is created by a pump which is pushing out the water droplets at a fixed rate. ( call it X ) - Does NOT change.

Changing the frequency of the strobe light ( call it Y ) is the integral part of the illusion.

The flow is similar to that of your shower head. The water droplets are continuously falling down. With the strobe light, we are just illuminating the droplets at different instances of time.

When X = Y —> The droplets appear stationary.

Imagine yourself to be sitting on top of the hose and watching every drop fall through. Whenever the droplet of water is about to leave the hose, the light flashes. This renders the droplet as stationary.

Let us call the distance between the droplets as L.

When Y > X — > The droplets appear to move up.

Now, the strobe light flashes a little too quickly than the rate of the drop falling. This gives us the illusion of droplets moving up since you are flashing the light before the droplet has traversed the distance L.

When Y < X — > The droplets appear to move down.

Now, the strobe light flashes a little slower than the rate of the drop falling. This gives us the illusion of droplets moving down since you are flashing the light after the droplet has traversed the distance L.

Thank you so much for expressing your concerns and I apologize if it had confused you. I hope this post made it up

Have a good day :)

EDIT - Here is the actual gif from the illusion of perception post.

Wow, “ For a photon, its entire existence is instantaneous. “ , that put things in perspective!

Ask Ethan #109: How Do Photons Experience Time?

Ask Ethan #109: How do photons experience time?

“[L]ight takes about 8 minutes to travel from the sun to earth. Light travels at the speed of light. If you do that relativity kicks in. So my question is, how much time passes for the photons traveling? In other words, how much have the photons aged when the reach the earth? Thanks for considering this.”

Travel at any constant speed, at rest, slowly, or near the speed of light, and you’ll experience time passing at the same rate it always does: one second per second. If someone else is moving relative to you, they’ll see your clock run slow (and you’ll see theirs run slow) depending on how quickly you move relative to one another. But what about a photon, which moves at the speed of light? From your point of view, no matter what your motion is, you won’t see time pass for it at all, and it won’t even experience time! For a photon, its entire existence is instantaneous.

Dog Chase - Switcher

I saw Regolo Bizzi’s wonderful drawings on twitter, and I had to try and make them in processing. I recognized it as a version of the dog chase problem (where dogs at each corner of a square are chasing the dog to their left), but now they switch from the left dog to the right dog every 100 frames. Also made a hexagon version (6 dogs), because why not?

How the f could a human do something like that? I want to see a video of that guy in action.

His name: Achim Leistner.

He is the master optician of the Avogadro project, an international effort to define the Avogadro constantwith maximum precision. He was asked to join the project from retirement as it was deemed that his expertise and craftsmanship were essential for the success of the project.

Here is a video: [x]

How beautiful!

Fibonacci you crazy bastard….

As seen in the solar system (by no ridiculous coincidence), Earth orbits the Sun 8 times in the same period that Venus orbits the Sun 13 times! Drawing a line between Earth & Venus every week results in a spectacular FIVE side symmetry!!

Lets bring up those Fibonacci numbers again: 1, 1, 2, 3, 5, 8, 13, 21, 34..

So if we imagine planets with Fibonacci orbits, do they create Fibonacci symmetries?!

You bet!! Depicted here is a:

2 sided symmetry (5 orbits x 3 orbits)

3 sided symmetry (8 orbits x 5 orbits)

5 sided symmetry (13 orbits x 8 orbits) - like Earth & Venus

8 sided symmetry (21 orbits x 13 orbits)

I wonder if relationships like this exist somewhere in the universe….

Beautiful, where can I get my hands on one of these? :)

Dragon Fractal - Level 5

If you take each of the 4 sides of a square and modify the angle of the dragon fractal as you go up, you get this shape. I’m still fighting the 3d models to get a nice smooth version.

Double Arm

This sketch was made by rotating point 1 around a circle, rotating point 2 around point 1, and then joining a line between point 1 and point 2. In the gif point 2 is traveling in the same direction as point 1. Point 1 is traveling at 1x, and point 2 is traveling at 2x. Following the gif are some of my favorite combinations of the periods:

Rotating same direction:

1x and 1x

1x and 2x

1x and 5x

2x and 1x

2x and 5x

5x and 8x

The last image is an array of all the varieties from 1x to 9x for each point.
