The Butterfly Effect is a philosophical analysis and personal point of view about relevant subjects in Physics. It shares with you my perspective about the well known butterfly effect and a possible application to our lives, Einstein and the Theory of Relativity, Geopphysics and Earth, probabilities, deterministic and nondeterministic realities and others. This book shares my perception about these subjects, and envisions to inspire the reader to look at science in a brighter light. Hopefully, you will feel motivated to think about exact sciences in a more apprachable way, letting go of a well known fear many people feel for them.
