The tiny bird flies in the blue sky. The sea reflects the blue of the sky. The blue reflection is the sea of the sky. The sea of the sky cried blue tears.
Among those blue tears, the tiny bird flies.
It flew through different colored worlds; the blue of tears, the orange of smiles, pink of sneezes and feverish cheeks, the red of anger.
It absorbed each color into its wings, until it was very beautiful. But, it wanted to go to more worlds, and it kept flying.
Eventually, the tiny bird absorbed too many colors.
Its wings became dirty, the colors muddied, and before long, its wings turned black.
Little bird falls and falls and keeps on falling.
Little bird has died.
Diversity is an important aspect of evolution in species.
With humanity containing a variety of differences, we are more easily able to adapt to change.
If humanity is all one kind, our fall will be statistically more likely in the long run. Let's tangent to an alternate scenario from communication technology to explain.
True Diversity Reception
True diversity is a technology built into most quality wireless mic receivers. In a true diversity system, two antennas are used, spaced at least a few inches apart, each receiving the same signal from the transmitter.
The receiver constantly measures the signal strength coming from both antennas, and switches to whichever antenna is picking up the stronger signal.
The reason for this is that as energy from the transmitter bounces around various surfaces in the room, sometimes reflections can interact with each other destructively, and cancel themselves out.
This causes what is commonly called a "dropout" - a momentary loss in signal.
Dropouts are location-based and dependent on the placement of both the antenna and the transmitter. When one antenna experiences a dropout, it is likely that the second antenna will have a strong signal.
While a true diversity system doesn't guarantee that there will be no dropouts, it will dramatically reduce them.
A diversity scheme is "true" diversity if the two antennas are connected to independent receiver modules.
In less-effective diversity schemes, the two antennas are connected to a single receiver, which cannot monitor the signal strength of both antennas at the same time. In these "quasi-diversity" systems, if the signal drops below an acceptable level, the receiver will switch antennas blindly, not knowing what the signal strength on the other antenna is until the switch is complete.
There are a couple of varieties of diversity, thus the term "true diversity" is a bit confusing. There are also differences in the way diversity is used in combination with other features to offer seamless protection against dropouts.
Some of these schemes work better than others, along with the increased cost and complexity of the solutions, thus the variance in resources needed to pursue them.
As in technology and communication, true diversity requires separation of both the transmitter and receivers in order to most effectively use them to acquire the best signal.
Diversity is strength and it must be protected by allowing it to flourish, not by combining colors but by protecting them all.
Everything in its right place
