e. The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
Now all the established truths which are formulated in the multifarious propositions of science have been won by the use of Scientific Method. This method consists in essentially three distinct steps (1) observation and experiment, (2) hypothesis, (3) verification by fresh observation and experiment.
1863 – Gregor Mendel 's pea plant experiments ( Mendel's laws of inheritance ). 1887 – Heinrich Hertz discovers the photoelectric effect. 1887 – Michelson and Morley: Michelson–Morley experiment, showing that the speed of light is invariant. 1896 – Henri Becquerel discovers radioactivity. 1897 – J.

1739 – David Hume 's Treatise of Human Nature argues that the problem of induction is unsolvable. 1753 – The first description of a controlled experiment using identical populations with only one variable is published, when James Lind, a Scottish doctor, undergoes research into scurvy among sailors.
The Satellite Test of the Equivalence Principle ( STEP) is a proposed (as of 2014 [1]) space science experiment to test the equivalence principle of general relativity. The experiment is thought to be sensitive enough to test Einstein's theory of gravity and other theories. The basic configuration is that of a drag-free satellite where an outer ...
Design of experiments with full (left), with second-degree polynomial (right) The design of experiments ( DOE or DOX ), also known as experiment design or experimental design, is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation.
