Quantum mechanics (QM) is a set of scientific principles describing the known behavior of energy and matter that predominates at the atomic and subatomic scales. The name derives from the observation that some physical quantities —such as the energy of an electron bound into an atom or molecule. The wave–particle duality of energy and matter at the atomic scale provides a unified view of the behavior of particles such as photons and electrons. Photons are the quanta of light, and have energy values proportional to their frequency. The mathematical formulation of quantum mechanics is abstract and it is implications are often non-intuitive .
To expplain nanotechnology you need to understand two things
The first is that nanotechnology is dealing which thing that are incredibly and infinitly small.
The human hair is one hundred thousand nanometers tick (100.000nm).
The secund thing that you need to understand about nanotechnology is that it`s way of controlling matter to make it do what we want it to do.
Nanotechnology is the building of structures to complex, atomic specifications by means of mechanosynthesis i.e. by chemical synthesis controlled by mechanical, nanometre scale devices enabling direct positional seleccion of reaction sites.
The fractal is an objetct which appears self-similar under varying degrees of magnification. Self-similarity is the major characterisics of the fractals objects.
Recient studies have attempeted with some succes to characterize certain parts of the body using fractal geometry. The cardiovascular system with regular beating of the human heart is an example of fractal.
The availability of accurate observational data led to research into theoretical explanations for the observed behavior. At first, only ad-hoc rules were discovered, such as Kepler's laws of planetary motion, discovered at the start of the 17th century. Later that century, Isaac Newton, bridged the gap between Kepler's laws and Galileo's dynamics, discovering that the same laws that rule the dynamics of objects on earth rules the motion of planets and the moon. Celestial mechanics, the application of Newtonian gravity and Newton's laws to explain Kepler's laws of planetary motion, was the first unification of astronomy and physics .
The astrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature, and chemical composition) of celestial objetcs and the interstellar medium, as well as their interactions.
Although astronomy is as old as recorded history, it was long separated from the study of physics. In the Aristotelian worldview, the celestial pertained to perfection—bodies in the sky being perfect spheres moving in perfectly circular orbits—while the earthly pertained to imperfection; these two realms were seen as unrelated.
Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe.This multidisciplinary field encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry and life on Mars and other bodies in our Solar System, laboratory and field research into the origins and early evolution of life on Earth, and studies of the potential for life to adapt to challenges on Earth and in space.
Although astrobiology is an emerging field and still a developing subject, the question of whether life exists elsewhere in the universe is a verifiable hypothesis and thus a valid line of scientific inquiry
In the 21st century, astrobiology is a focus of a growing number of NASA and European Space Agency Solar System exploration missions.
