Topic 1.) Technique-16, Experimental Evidence

|||

Technique-16, experimental evidence, can be used to support the validity of the statements you are writing.  Experimental evidence is also information that can be used to solve a problem or obtain a goal.  The experimental evidence can come from published sources, or from experiments that you, or someone you know carried out.  The utility of this concept, and its potential use in writing, will become apparent after you read this chapter.

 

 

Subtopic, Experiments, and Experimental Evidence

|||

I am using the term experiment and experimental evidence, in this e-book in a very broad and general way.  Based on the general way I am using the terminology, experiments are carried out to obtain information.  This can involve experiments to determine if a hypothesis is correct, or incorrect.

      An experiment is successful if it proves that the hypothesis is true, or false.  An experiment is not successful if it does not confirm or refute the validity of the hypothesis.  Sometimes experiments that fail provide interesting or valuable results that are unrelated to the hypothesis. Experiments can be considered partly successful, if they provide at least some supporting evidence indicating the truth or falsity of the hypothesis.  

      Experiments involving complex systems, such as social groups, human physiology, and ecological systems, usually provide less than perfect results.  Experiments of this nature often involve statistical evaluations indicating the probabilities of a hypothesis being true or false.  There are complex mathematical techniques for calculating the probabilities.  However, in real life situations, the probabilities and experimental results in general, can be influenced inadvertently or intentionally by social and psychological factors.  This is explained in more detail in the following subtopic.

 

 

Subtopic, Note, Some Published Sources and Individuals Might Consider an Experiment Successful Only if it Confirms the Validity of the Hypothesis

|||

Some sources, and individuals, might consider an experiment only if it proves that a hypothesis is correct.  Thinking in this way, might increase the chances of manipulating the experimental setup, so that it confirms the validity of a hypothesis that might be incorrect.  This can happen inadvertently, and in some cases intentionally, when the researcher is focused on proving the validity of his or her hypothesis.  This probably happens frequently, because there are many disagreements about the validity of various hypothetical concepts.  This can involve researchers who favor a hypothesis, using less-than-perfect experimental setups that confirm their assumptions, and vice a versa. 

      Based on the definition I provided in the previous subtopic, an experiment is successful if it proves that a hypothesis is correct or incorrect.  However, if a researcher carries out a successful experiment that disproves his or her hypothesis, he or she will usually not be rewarded for the results.  The experimenter might decide not to publish such results.  In addition, the scientific journals might refuse to publish the results. 

      However, if an experiment proves that an established theory, or widely accepted hypothesis to be false, the experimenter would receive great rewards for his or her efforts.  This is assuming that the scientific community believes the experimental results to be valid.

 

 

Subtopic, Experiments that Do Not Involve a Hypothesis

|||

However, based on the general way I am using the terminology, an experiment does not have to involve a hypothesis.  Experiments can be set up to determine what will happen under a specific set of conditions.  A simple example is mixing two or more chemicals together to see what will happen.  Experiments can also involve an evaluation to determine the utility and/or functionality, of a strategy, method, product, or invention.  Experiments can involve testing to see what works, and what does not work.

 

 

 

Topic 2.) Formal and Informal Experiments

|||

Experiments can be divided into two broad categories, which I call formal, and informal.  Formal experiments are carried out with great care, and with strategies that would minimize the chances of obtaining erroneous results.  Informal experiments are carried out in a simpler and less precise way than the above.  These concepts are explained in detail in the following subtopics.

 

 

Subtopic, What are Formal Experiments

|||

Based on the way am using the terminology, formal experiments are carefully carried out, using various strategies and equipment to avoid errors or erroneous results.  Formal experiments may involve a comparison between an experimental group, and a control group, such as when evaluating medications on humans or animals.  In such a case, the control group receives a placebo, and experimental group receives the experimental medicine.  The placebo group and experimental group are compared to determine if the medication is effective.  Similar techniques involving controls are used in human behavior experiments, such as in psychology, and social psychology.

      Formal experiments that involve chemistry and physics might not require the type of controls described above.  For example, if a chemist is trying to create a new aluminum alloy, he or she, will mix aluminum with other metals, using high-temperature.  This would be repeated many times to produce large number of aluminum alloys.  Then, each alloy would be tested to determine its properties, such as tensile strength, compression strength, melting point, resistance to corrosion, and potential utility.

      Sometimes controls, that are more or less similar to the controls described in the previous paragraph, are required in the physical sciences.  For example, if a sample of water is evaluated for purity, using a new experimental testing device, controls should be used.  This can involve evaluating two samples of water using the new technique.  The experimental sample would be contaminated with a carefully measured level of contaminants.  The negative control sample would be distilled water.  If the experimental testing device functions properly, it will indicate the quantity of impurity in the contaminated sample.  It will also indicate that the distilled water has no contaminants.

 

 

Subtopic, What are Informal Experiments

|||

In general, formal experiments are time-consuming, expensive, and relatively difficult to carry out.  Based on the way amusing the terminology, Informal experiments are carried out with less precision, and do not involve all of the strategies used with formal experiments.  Informal experiments can usually be carried out with much less time, less effort, less money, and less equipment, then formal experiments.  However, these experiments can sometimes produce erroneous results.  Thus, the information obtained from an informal experiment generally is not suitable for publication in scientific-journals. 

      The major advantage of an informal experiment is it can be carried out with only of fraction of the expense, time, and effort of a formal experiment.  Thus, it is usually feasible to carry out many informal experiments, which can produce a large amount of information.  The information might include some useful or interesting results, as well as some imprecise, ambiguous, and/or erroneous results.  However, the results of informal experiments can always be refined and carefully evaluated with formal experimentation.

 

 

Subtopic, Carrying Out Informal Experiments, to Test the Efficacy of Plans to Carry Out a Formal Experimental Project

|||

When planning a formal experimental project, it is usually best to carry out informal experimentation first.  This can involve an initial evaluation of a hypothesis with informal experimentation.  If the initial results are disappointing, an alternative experimental project can be devised.  This can avoid wasted time, money, and effort. 

      However, if the informal experiments yield promising results the project can be carried out.  If a research grant proposal is needed for funding, it might be advantageous to describe the informal experiments in the grant proposal.  This is assuming the informal experiments were carried out with a reasonable level of care and precision.

Topic 3.) Writing with Experimental Evidence, and How To Support the Validity of the Experimental Evidence

|||

When presenting experimental evidence, ideally you should include supporting material to convince the reader that the evidence is valid.  If you obtained the experimental evidence from reliable published sources, the conventional citations would be adequate in this regard.  However, obtaining additional information from other authors that confirm the validity of the experimental evidence would produce a statement that is more convincing.  Keep in mind that experimental results from one researcher might confirm a hypothesis, and the results of another researcher might refute the hypothesis.

      If you carried out the experiment yourself, you may be able to support your results by explaining exactly how you carried out the experiment.  This must be done in such a way that the reader with appropriate training can reproduce your experiment, to check its validity.  Experimental results are not considered valid if they cannot be reproduced by others.  In addition, demonstrating your experiments, in person, on video, or over the Internet can also be useful for convincing the readers that your evidence is valid. 

      The following subtopic, presents an example that shows how experiments carried out by the writer, can be used to support the validity of his text.

 

 

Subtopic, An Example of a Writer Using his Own Experiments And Related Evidence, to Support the Validity of his Text

|||

I wrote a very short 5000 word web-based e-book early in 2016.  The validity of some of the statements in this e-book, are supported by the results of experiments I carried out.  The e-book is titled: Experiments with the Filesystems Used on the Web and Personal Computers, Reveal Potentially Useful Techniques.  This e-book can be access from www.TechForText.com/EXThis e-book is a good example of a writer using his own experiments to support the validity of his text. 

      The experiments presented in the e-book function over the web when the reader clicks on the web link.  This supports the validity of the experiments, and related evidence.  The e‑book also contains all the information needed to reproduce the experiments, which is additional evidence supporting the validity of the experiments.  The e-book also contains some material that is supported by web-based articles and videos from other authors.
