Scientific Methods

The scientific method seeks to explain the complexities of nature in a replicable way, and to use these explanations to construct useful predictions. It provides an objective method to find solutions to problems in a number of scientific and technological fields. Often scientists have a predilection for one outcome over another, and scientists are conscientious that it is vital that this preference does not bias their interpretation. A strict following of the scientific method attempts to minimize the pressure of a scientist's bias on the outcome of an experiment. This can be achieved by correct experimental design, and a thorough peer assessment of the experimental results as well as conclusions of a study.

Scientists use models to refer to a explanation or depiction of something, specifically one which can be used to construct predictions that can be tested by experiment or observation. A hypothesis is a disputation that has been neither well supported nor yet ruled out by experiment. A theory, in the context of science, is a logically self-consistent model or framework for recitation the behavior of certain natural phenomena. A theory typically describes the behavior of much broader sets of phenomena than a hypothesis — commonly, a large number of hypotheses may be logically bound together by a single theory. A physical law or law of nature is a scientific generalization based on a adequately large number of empirical observations that it is taken as fully verified.

Sun catchers

A suncatcher is something like the optical equivalent of a wind chime, and certainly many designs unite both the two. The most common window-hanging style brings attraction and panache to any room. Choose a color and pattern that harmonizes your decor. Window-hanging sun catchers can be the focal point of a room. Whichever you choose, you'll be delighted with the beauty sun catchers add to your decor. Sun catchers aren't limited to windows. You can also find sun catchers for your garden, indoor plants, and for the rear view mirror of your car or as garden stakes, to append color to your flower garden in the off-season. While glass sun catchers are the most popular, don't forget about crystal sun catchers that reflects prisms of light, and lucid stones such as thinly sliced agate that make stunning natural sun catchers. There are sun catchers with pressed flowers, beads, gemstones, and even character themes for a child's room.
