Usage: Assumptions, laws and theory refer to various assertions made by scientists on natural phenomena. The hypothesis is a proposition to explain a series of facts in a unified way. It usually constitutes the experimental basis for establishing its rationality. Simplicity, elegance, and consistency with previously established assumptions or laws are also the main factors in determining acceptance of assumptions. Although it will never prove that the assumption is correct (in fact, the assumptions make facts that are not normally explained), they can sometimes be validated in the context of a specific theoretical approach without doubt . Science law is a hypothesis that is considered universally correct. This law has outstanding predictability and scientists (or engineers) can model the physical system and predict what will happen under various conditions. In addition to the appropriate law, new assumptions are often rejected unless major changes are made to the method. Although an example is established, it is a conservation law of energy, but it must obey the principle of revolutionary appearance and uncertainty of quantum mechanics. The theory is a series of statements, including laws and assumptions, used to describe a series of observations or phenomena. Therefore, the theory can explain a wider range of events than the law. Once new data is repeatedly tested and used for accurate forecasting, the theory is widely accepted. The theory usually contains assumptions that can be modified yet, but it may be difficult to know the end of the hypothesis and the beginning of law and theory. For example, Albert Einstein 's relativity theory contains sentences that were originally thought to be hypothetical (and bold). However, the assumptions of relativity all came to the authority of the laws of science, and Einstein's theory superseded Newton's law of motion. In some cases, such as bacterial theory of infectious diseases, the theory was completely accepted, it is no longer called the theory.

In science, a statement of a possible interpretation of some natural phenomena. We verify the hypothesis by deriving conclusions therefrom; if the observations and experiments indicate that the conclusion is wrong, the assumption must be wrong. (See scientific method and theory.)

What is the hypothesis? Hypothesis (complex hypothesis) is a description of recommendations for observation. The definition depends on the theme. For example, in science, assumptions are part of the scientific approach. This is a prediction or explanation by experimental test. Observation and experimentation may refute the scientific hypothesis, but it does not prove it completely. For example consider the possible relationship between good sleep and getting good grades. The null hypothesis states that "the number of hours students sleep is unrelated to their grades," or "there is no correlation between their sleeping hours and grades." Experiments validating this hypothesis include collecting data and recording the average sleeping time and performance of each student. The assumption may be rejected if the student who normally takes 8 hours of sleep is better than a student who has 4 hours of sleep or 10 hours of sleep.

The null hypothesis is a practical hypothesis that can be refuted by a statistical test supporting the alternative hypothesis. Instead of trying to "prove" your thought (alternative hypothesis) you have to prove that the null hypothesis may be wrong. You must "refute" or "withdraw" the null hypothesis. Before you find the opposite evidence, you must assume that your alternative hypothesis is wrong. Carl Popper said, "All swans are white and can not be seen through some observations of white swans - we may not be able to see a black swan somewhere - but it is true You can pass black swans therefore it may be counterfeited, but this universal form of scientific theory can not be verified in the end.
