Many years ago MIT dug into it's archives and gathered together what it called it's "crank" files. An example is the story of Seabury Brewer. What you read below is courtesy of MIT...
Seabury Doane Brewer made no less than 124 discoveries. His poster-sized treatise entitled, "124 Discoveries Made between 1892 and 1930 by Seabury Doane Brewer, of Lake George, New York, and Montclair, New Jersey," contains the revelation "that temperature, with its variations, is one of the most wonderful things, and is always present everywhere," and "that physicians should be compelled to destroy all unfit specimens of humanity immediately upon their birth." At the time of publication Brewer was in his seventieth year and still making discoveries.
Brewer didn't restrict himself to just one field of science, or to even just science. The subjects he explored include: Psychology, Government, Life, Evolution, Miscellaneous, Education, Astronomy, The Laws-of-Nature, Fire Balls,--of Lightning, Shadow Bands,--of Sun's Eclipses, Northern Lights, Radio, Mathematics, "Nothing" and Myself; he also adds a postscript concerning atoms and comets.
Though there isn't room here to list all 124, the following abbreviated list of Brewer's Discoveries is a fair representation of the type of material found in the archive:
1. That our thoughts have been, are being, and will be, thought by other thinkers.
28. That there is no such thing as Platonic love between normal males and females.
30. That umbilical cords should be allowed to wither away naturally. (I will wager that Methuselah did not have his umbilical cord monkeyed with.) Man alone interferes with the impregnation, interferes with the embryo, and interferes with birth. How unfair to the child. Watch the animals, birds and insects; watch all things in their various processes of being born.
39. That the inexorable economic law of supply and demand is a fake,--as well as many another economic law.
52. That phonetic spelling should not be allowed.
69. That twin stars do not exist. That what is seen is the result of (caused by) optical reflection.
70. That Saturn's ring does not exist. That what is seen is the result of (caused by) optical reflection.
Discovery #108, isn't really a discovery; it's the story of Brewer's correspondence with Einstein and a "Mr. Poor," which he carried on under his astronomical noms-de-plume, "Mrs. Mary Bryant" and "Shirley Brown":
108. That a "5 diagramed paraphrase" explains why it is that Einstein has not yet reached the goal. The paraphrase, and the construction of it, occurred under the following circumstances.
On March 27, 1929, (in the name of "Mrs. Mary Bryant," my astronomical nom-de-plume, although it happens to be the only time I ever wrote a letter in that name) I wrote Albert Einstein, enclosing one dollar, for an authentic translation of his latest article, --which I have never received, and he still has my one dollar.
Without looking the matter up, I think that he (Einstein) was reported to have said, at that time, that "gravitation" is "electricity."
In my ("Mrs. Mary Bryant's") letter to him I said that long ago I had discovered that all things (even gravitation, magnetism, electricity, chemistry, and even Life itself) are so interwoven, intermingled, and mixed up together, that it is almost impossible to tell where one thing leaves off and an other thing begins. ...
Brewer is a good example of someone who wants to replace the scary and impenetrable theories of 20th century science with good old-fashioned common sense, or, in some cases, a strange admixture of common sense and strong opinions.
