" BUTTERFLY EFFECT "

I would like to refer Theory of Butterfly -Effect at the moment we consider over-
1- Importance of small actions in deciding life-achievements .
2- Initiatives even at thought level (motivation & attitudes .)
3- Interdependence of events & universe .
4- Theory of Action & Fate at large . Theory of Cause & Effect at large .
5- Oneness of the Universe & interdependence .
* A note /summary of BUTTERFLY EFFECT is given for your understanding -
Term "butterfly effect" itself is related to the work of *Edward Lorenz, and is based in chaos theory and sensitive dependence on initial conditions, already described in the literature in a particular case of the three-body problem by Henri Poincaré in 1890. The idea that one butterfly could eventually have a far-reaching ripple effect on subsequent historic events . Lorenz made the term popular. In 1961, Lorenz was using a numerical computer model to rerun a weather prediction, when, as a shortcut on a number in the sequence, he entered the decimal .506 instead of entering the full .506127 the computer would hold. The result was a completely different weather scenario.Lorenz published his findings in a 1963 paper for the New York Academy of Sciences noting that "One meteorologist remarked that if the theory were correct, one flap of a seagull's wings could change the course of weather forever." Later speeches and papers by Lorenz used the more poetic butterfly. A butterfly’s wings in Brazil set off a tornado in Texas?, Although a butterfly flapping its wings has remained constant in the expression of this concept, the location of the butterfly, the consequences, and the location of the consequences have varied widely .
The phrase refers to the idea that a butterfly's wings might create tiny changes in the atmosphere that may ultimately alter the path of a tornado or delay, accelerate or even prevent the occurrence of a tornado in a certain location. The flapping wing represents a small change in the initial condition of the system, which causes a chain of events leading to large-scale alterations of events. Had the butterfly not flapped its wings, the trajectory of the system might have been vastly different. While the butterfly does not "cause" the tornado in the sense of providing the energy for the tornado, it does "cause" it in the sense that the flap of its wings is an essential part of the initial conditions resulting in a tornado, and without that flap that particular tornado would not have existed.

*Edward Norton Lorenz(1917-2008) U.S. meteorologist. Following degrees from Dartmouth College and Harvard University in mathematics, he turned to weather forecasting in 1942 with the U.S. Army Air Corps. After World War II he joined MIT as a researcher, earned a doctorate in meteorology (1948), and stayed on as a professor. In the early 1960s, he discovered that the weather exhibits a nonlinear phenomenon known as sensitive dependence on initial conditions (see **chaos theory). He explained this phenomenon, which makes long-range weather forecasting impossible, to the public as the "butterfly effect": in China a butterfly flaps its wings, leading to unpredictable changes in U.S. weather .

** chaos theory -Mathematical theory that describes chaotic behavior in a complex system. Applications include the study of turbulent flow in fluids, irregularities in biological systems, population dynamics, chemical reactions, plasma physics, meteorology, the motions of groups and clusters of stars, transportation dynamics, and many other fields.
