Is our universe mathematical? Or its just in our head?

Decoding the Universe. The great math Mystery.

Please do watch it.

Minimum two things are required to describe anything. Because one of it is taken the reference to say that this is not the same object as other. This is perhaps the fundamental principle, which we humans are limited by.
Why do I say minimum two things? I have written it on article:

Minimum two different things are required to describe anything.

To reach this conclusion, let's find out what we see or know. We know things by knowing their shapes.  But how to know the shape of a particular object. For it, we have to know the distance (the way of arrangement of the object). But again the question arises, how we know the distance. What makes us aware of the distance?

Let's take an example of colored board problem.
Imagine a one red colored board. Also, imagine we are only seeing it and nothing else. Can we distinguish anything from it? We only see red and nothing else. Take an analogy of a person with eyes closed. When he/she enters the room, he/she can't distinguish between  a chair, a table, a bed. He/she even can't say the particular object exists or not.

Now come again to the colored board problem. Now another big black color circle comes on the board. But how do we know it, it's a circle, not a square?  To know it we should be aware of distance. With using distance, we can tell whether it's a circle or square. It's because we have a tendency to measure distance, we can distinguish between a square and circle.

But how does distance arises in our mind?
We measure distance by counting. But how do we do counting here? We can only say that red is different from black. We can't count anything in it. How the numbers are so intuitive in our brain. We can't count a number of red dots on the board, neither we can count the number of black dots (circle) on the board.
So there is something that makes us count. It's a reference. The SMALLEST reference.
Imagine a smallest black dot in the board, surrounded by red color. Now take it  (the smallest black dot)  as the reference.
Now we are ready to say whether the black one is a circle or a square by counting. Just start putting the smallest reference black dots in the black circle line by line and measure no. of dots in each line. The first line would have one dot. The second line would have two dots, third 3  dots and at diameter maximum number of dots, then when we go down, the dots decreases and reaches to one again.

Bingo.. we know counting now.

Perhaps our limitation is based on this principle.

The matter is quantized as there is a demarcation between two objects, i.e. we can distinguish between objects but space is not as there is no demarcation is space.
Oops, we can demarcate space with matter. But as space is only one (i.e. very huge), it won't possible for matter particles to demarcate it if we take complete universe...

Listen feedback to take decisions, Feedback is Universal.

The feedback mechanism is universal in all life forms. Without feedback mechanism, there wouldn't be evolution, there would be homeostasis, nor there would be human existence. Let me explain how feedback mechanism helps in maintaining homeostasis, how it can be easily applied real life situations.

Feedback at molecular level in cell can be divided into following types

Reference: Molecular Biology of Cell, Bruce Alberts et al. 
Arrows indicate positive control, i.e  A increases productions of more As
Lines with bars depicts negative control, i.e.  A decreases the productions of more As.
Last two figures in right indicate more complicated versions of feedback.

Because of these kinds of feedback, complete homeostasis is maintained. Without feedback, we wouldn't feel hungry, we won't feel the heat, we wouldn't have the life at all.

If these feedback mechanism does not work properly, then there would be turmoil in our body without homeostasis. Feedback is not only important inside our body, it's also important when we take the whole community. The simplest example would be bacteria with a process called quorum sensing.

When we expand feedback to ecology, its top down and bottom up effect.

" The first, called bottom-up control, states that it is the nutrient supply to the primary producers that ultimately controls how ecosystems function. If the nutrient supply is increased, the resulting increase in production of autotrophs is propagated through the food web and all of the other trophic levels will respond to the increased availability of food (energy and materials will cycle faster).

The second theory, called top-down control, states that predation and grazing by higher trophic levels on lower trophic levels ultimately controls ecosystem function. For example, if you have an increase in predators, that increase will result in fewer grazers, and that decrease in grazers will result in turn in more primary producers because fewer of them are being eaten by the grazers. Thus the control of population numbers and overall productivity "cascades" from the top levels of the food chain down to the bottom trophic levels. " References:

So all these are nothing but feedback.

We all use feedback in day to day life to make decisions, without being much aware of its importance and its universality.

But in order to maintain homeostasis in our life, we should always listen to feedback to know what works and what doesn't. It's no point to repeat the things that don't work. e.g. If A promotes the formation of B and  B at the certain level is harmful to our body, then we should stop producing more As.

So, we should always listen to feedback and take action based upon it.
