What is butterfly effect ?

 In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state. The term is closely associated with the work of mathematician and meteorologist Edward Lorenz.





What is butterfly effect in simple terms ?

The butterfly effect is an idea that is more commonly used in chaos theory. A small change can make much bigger changes happen; one small incident can have a big impact on the future. The idea started from weather prediction. ... This term can be used in areas other than weather.









What is butterfly effect theory ?

The butterfly effect is the idea that small things can have non-linear impacts on a complex system. The concept is imagined with a butterfly flapping its wings and causing a typhoon. Of course, a single act like the butterfly flapping its wings cannot cause a typhoon.





IS butterfly effect is dangerous?

The butterfly effect is the semi-serious claim that a butterfly flapping its wings can cause a tornado half way around the world. It's a poetic way of saying that some systems show sensitive dependence on initial conditions, that the slightest change now can make an enormous difference later.







Can  butterfly effect cause tsunami ?

Put more simply, this is the so-called butterfly effect: the light fluttering of butterfly wings may cause unpredictable consequences or, more graphically, can lead to large-scale phenomena like tsunamis.






What is the butterfly theory is love ?

Observing the meaning of the butterfly effect, the most common definition of the term I found was, that it is a metaphoric term. However, in theory, it means something small in statures like a bird or a butterfly could flap its wings and make a great event happen in another part of the world.





Mathematical Definition of butterfly effect ?

Recurrence , the approximate return of a system towards its initial conditions, together with sensitive dependence on initial conditions, are the two main ingredients for chaotic motion. They have the practical consequence of making complex system, such as the weather, difficult to predict past a certain time range (approximately a week in the case of weather) since it is impossible to measure the starting atmospheric conditions completely accurately.

A dynamical system displays sensitive dependence on initial conditions if points arbitrarily close together separate over time at an exponential rate. The definition is not topological, but essentially metrical.

If M is the state space for the map , then  displays sensitive dependence to initial conditions if for any x in M and any δ > 0, there are y in M, with distance d(. , .) such that  and such that

for some positive parameter a. The definition does not require that all points from a neighborhood separate from the base point x, but it requires one positive lyapunov exponent 

The simplest mathematical framework exhibiting sensitive dependence on initial conditions is provided by a particular parametrization of the logistic map 

which, unlike most chaotic maps, has a closed form solution 

where the initial condition parameter  is given by . For rational , after a finite number of iteration    maps into a periodic sequence . But almost all  are irrational, and, for irrational  never repeats itself – it is non-periodic. This solution equation clearly demonstrates the two key features of chaos – stretching and folding: the factor 2n shows the exponential growth of stretching, which results in sensitive dependence on initial conditions (the butterfly effect), while the squared sine function keeps  folded within the range [0, 1].

what is secret of 369

  The number 3 serves as the only number that equals the sum  of  all preceding numbers (0 + 1 + 2 = 3). Also, when 3 is added to itself, the smallest perfect number ensues (6). And when 3 is squared, the result is the number that completes the single-digit numbers in the decimal system, better known as the number 9 why 369 is universe of key ? Nikola Tesla was obsessed with numbers, but especially 3, 6 and 9. He wanted the world to know the significance of the number 3 6 9, he claimed that these were extremely important numbers, but the question is why? What was that Nikola Tesla wanted the world to understand? How it became Nikola Tesla 3 6 9 theory? To understand that, we must first know about Mathematics. Why it is so different yet the same anywhere in the universe. Maths was and has been the most valued subject of all the time and the most powerful too. Two plus two will always be four everywhere in the universe. Possibly Nikola Tesla knew the power of the numbers 3 ...

Anthropic principle

  The   anthropic principle   is the principle that there is a restrictive lower bound on how statistically probable our observations of the universe are, given that we could only exist in the particular type of universe capable of developing and sustaining sentient life.   Proponents of the anthropic principle argue that it explains why this universe has the  age  and the  fundamental physical constants    necessary to accommodate conscious life, since if either had been different, we would not have been around to make observations. Anthropic reasoning is often used to deal with the notion that the universe seems to be  fine tuned . There are many different formulations of the anthropic principle. Philosopher Nick Bostrom  counts them at thirty, but the underlying principles can be divided into "weak" and "strong" forms, depending on the types of cosmological claims they entail. The  weak anthropic principle  ( ...

Kardashev scale

  The   Kardashev scale   is a method of measuring a  civilization ' s level of technological  advancement based on the amount of energy  it is able to use. The measure was proposed by   Soviet    astronomer   Nikolai    Kardashev    in 1964. The scale is hypothetical , and regards energy consumption on a cosmic  scale. Various extensions of the scale have since been proposed, including a wider range of power levels (types 0, IV through VI) and the use of metrics other than pure power. Categories  The Kardashev scale has three designated categories, these are: A  Type I civilization , also called a planetary civilization , can use and store all of the energy available on its planet.  A  Type II civilization , also called a stellar    civilization , can use and control energy at the scale of its planetary system. A  Type III ...
