1. It‘s a busy book, taking place across many continents and time frames, from the second world war to modern day America to a Jihadist training camp, following the butterfly effect of each action to its bloody denouement.

2. A chaotic system is characterised by extreme sensitivity by all perturbation (disturbance or agitation). This is the basis of the so–called Butterfly Effect [the theoretical idea that the flapping of a butterfly‘s wings can produce a storm half way across the world]. Now science has got good enough that to some extent we can ask this question: If we desired to create some alteration in the atmosphere, and we can go back in time, what kind of butterfly – what kind of perturbation – should we introduce and just were and when?

3. Lorenz, a meteorology professor at the Massachusetts Institute of Technology, discovered a butterfly effect related to the study of weather and its patterns during the 1'60s and 1'70s and found, according to the American Physical Society, that "systems that are so sensitive to measurement that their output appears random, even though there is an underlying order." The discovery, according to the American Physical Society‘s APS News on its Web site was a "serendipitous discovery that subsequently spawned the modern field of chaos theory and changed forever the way we look at nonlinear systems like the weather." Lorenz‘s studies of the dynamics of atmospheric circulation has given better understanding to what is called the chaotic behavior of modeling weather systems using mathematics.
