Yellow Ball

If I was to put a yellow ball in front of you and ask what colour the ball is, you would confidently say “yellow”. As you say, the ball appears yellow, but the answer is technically wrong. Strictly speaking, the ball itself is not yellow – it is merely reflecting the colour yellow. The ball only appears yellow because we see the yellow part of the natural light spectrum bouncing off the ball. We cannot say that the essence of the ball is “yellow”. For example, if you were to look at the ball through a red lens, the yellow light would be filtered and you would see a black ball. A person with a certain kind of colour blindness would say the ball has a bluish hue. A butterfly, which sees the ultraviolet spectrum as well, would see a colour we cannot even name.

Human beings judge objects using the vision. We describe an object as we see it and store that information in our brain to define the object. For this purpose, the fact that a colour blind person or a butterfly sees the ball a different colour is irrelevant to us. All we need to know is that object appears yellow to us. But this is only the case for objects. Let us imagine the ball is a person. If everyone in the world sees you as a yellow ball, would that make you a yellow ball? Of course not. However, people worry too much about how others see them. Although other people’s perception does not change our true nature in the slightest, we even go as far as erasing or abandoning our nature to look good in front of another person. Thus, whether our essence is white, black, red, blue or technicolour, when others see us as yellow, we have a tendency to try desperately to become yellow. 

If the world says you are a yellow ball, act crazy and be a red ball. There is not a single reason you should have to hide your true nature. Have confidence in your essence. There is nothing wrong with that.

Time Perception

What exactly is the present? The present is the middle point between the past and future, the world that we experience and perceive on a real-time basis. But would you believe it if the world you perceive is not the true “present”? To experience the world, we use our five senses. The brain collates all these sensory information and processes it to construct “the present”. This process takes about 80 milliseconds. Ergo, the world we experience is actually the world as it was 80 milliseconds ago. For a similar phenomenon, consider the stars. The stars we observe are not what they look like now, but what the stars looked liked when they emitted the light that we see. Thus, the star you are looking at may not even exist anymore.

But 80 milliseconds is a very short time; surely it has no impact on our everyday life? To prove that this delay has a critical impact on our understanding of cause and effect, neuroscientists designed the following experiment. The researchers would ask the participant to press a button that caused a light to blink after a short delay. After about ten tries, the participants reported that the delay had disappeared and the light flashed immediately after they pressed the button. This was due to their brain editing out the time delay and directly connecting the cause (button) and the effect (flash). But a much more peculiar phenomenon was seen when the researches removed the delay between the button press and the flash. Participants reported that they saw the light flash before they even pressed the button. The participant’s brain had become so used to the editing process that it was confusing the order of the cause and the effect.

The brain’s time-editing ability can be seen in the following simple experiment. If you touch your nose and toe at the same time, logic dictates that as the toe is further from your brain, the signal will have to travel further and it will be felt later. But in reality, you feel both at the exact same time. This is because your brain uses a map of the body to edit the relative time the signal takes to reach the brain to better construct a “real-time present”.

Dimensions: Exploring The Dimensions

In the 21st century, films and television have evolved to show 3D images. However, most people only have a crude understanding of what dimensions actually mean. This is a guide that will explore the incredible journey from a zero-dimensional point to a tenth-dimensional point and all the wonderful lines and folds that lie in between.

A point in space has no area – this is the zeroth dimension.
When two points are connected, it forms a line – the first dimension. This line allows one to travel from one 0D point to another, introducing the concept of length.
Another line is drawn branching off this line in a different direction – we have entered the second dimension. Now we have the concept of width.
By adding another concept – depth – we ascend to the third dimension. Now it is possible to go from one point on a 2D surface to another as we have “folded” a branch in the second dimension to meet the other branch. A simple explanation would be lifting your finger off one point and placing it on another point.

To simplify our journey to the third dimension we have:

  • Assumed a “point” in space as a dot (.)(0D)
  • Joined” two dots to form a line (|)(1D)
  • Branched” the line to create two ends (Y)(2D)
  • Folded” the branches together to make the two ends meet (P)(3D)

These four concepts of point, joining, branching and folding are crucial in understanding how the different dimensions interact.

An interesting thought regarding the concept of dimensions is perception. How would inhabitants of each dimension view different dimensions? This is easy for lower dimensions (2D and below) because we can see them as a dot, line, square and cube (our dimension). Ergo, we can easily understand all the concepts of the lower dimensions (e.g. width). However, the opposite would not be possible (e.g. a 2D being trying to understand depth) as the concept does not exist in their dimension.

To further explore this thought, we must explore the world of Flatland.

Rabbit Or Duck

image

What do you see in the above picture? A rabbit? A duck?
This image shows a phenomenon first described by an American psychologist, Joseph Jastrow, in 1899 and tells us a few things about the brain’s way of processing visual information.

Firstly, this picture is neither a duck nor a rabbit. However, our brain tries to match it to what it has seen in the past, and in that process (for example) it decides it must be a rabbit. Then when the same picture is presented, it decides it must be a duck, because the picture appears to match both figures and the brain randomly decides it can only be one of them.

This experiment proves that the human brain does not simply record visual information on to film (memory), but instead processes it first then records it. This is the reason we see UFOs in clouds, the face of the Virgin Mary on burnt toast or a rabbit on the moon. This phenomenon is called pareidolia, when the brain gives a meaning to what is actually a random visual stimuli. Due to this, we cannot totally trust what we see.

Also, this picture teaches us a valuable lesson regarding our perception. From one point of view it is a rabbit, but from another it is a duck. This kind of scenario is seen countless times in life, such as a song you hated that suddenly sounds great, or a guy you once thought was a tool appearing wonderful all of a sudden, or a girl you never even considered becoming attractive one day.
Like this, perception can not only be affected by optimism and pessimism, but even small things like emotions or random events.
