CYCLES

In many physical, biological and social systems, changes in one direction tend to produce opposing, leading to repetitive cycles of behavior. This relates to how there are repetitive cycles to everything in the world. When there is a change in one cycle it will lead to an opposite cycle. This is true in really any cycle. In the physical world, this is similar to the process of precipitation. The precipitate or rain falls to the ground and is evaporated up into the air, where it is stored in a cloud. The cycle continues.
This also relates to positive and negative feedback loops, as learned in principle of biomedical sciences class. Feedback loops are cycles of behavior. They can be anything from cycles of electricity to cycles of blood in the body. Positive feedback loops change in a favorable way, meaning it is more of an expected result. Whereas in a negative feedback loop, the results are inverted.
Even life cycles are repetitive. Everything from human’s daily routine (we wake up, brush our teeth, eat breakfast go to work) to our histories (history repeats itself) are repetitive cycles. Therefore, everything is subject to the “domino effect.” One change causes an opposing behavior, restarting the cycle.

Questions to consider:
1. Does the change always produce an opposite; can there be a change with no repercussions?
2. Do all cycles break after some time?
3. Can a cycle be broken without using an opposing force?

  2. Ms. Schwartz,

    Your "water cycle" example is first rate. Many of your other classmates also spoke of "circadian rhythms." Well done.
