experiment

Perform the various measurement under the various conditions about the object that a prediction is difficult from confirming whether a built hypothesis and an existing theory really apply to it with the experiment and an existing theory.
One of the technique to get knowledge.

The experiment is one of the scientific basic methods with observation (I include the measurement).
But I add some kind of operation to it by the experiment whereas I am similar as the figure, and observation is going to know object itself and examine a change to have in an object to produce thereby and am going to start some kind of conclusions from there.
It is called a supplementary examination to check whether the result of a certain experiment is right.

In the engineering, I can classify it in an experiment of the model and an architectural experiment.

There is the case that a word to be experimental is used in the meaning of the trial before a case and the public performance with the technique that is new at a more general place.
There is the expression that I called "experimental technique".

The experiment is generally performed to inspect a hypothesis.
When it is performed without a hypothesis really, there is it, but the normal is based on observation and knowledge known by then and expects it when there may be such a structure and a law there.
And I judge it if the expectation is right when such a result will appear if I carry out such an experiment.
Therefore I check this expectation by really performing it.
The imagination may have been right if it proved right.
I understand that at first it was a mistake if I do not prove right.
