Sidis Archives

William James Sidis (SIGH-dis), the world-famous child prodigy said to have been a "prodigious failure," actually wrote many books, articles, and periodicals under pseudonyms. In addition, there are as many as ten manuscripts not yet found.

The W. J. Sidis Archive presents here all of his writings found so far: four books, four pamphlets, 13 articles, four periodicals (36 issues), 89 weekly magazine columns, selected letters, financial documents, a proposal and design for a corporation owned by its employees, and one wonderful invention. There is also some biographical material including Dr. Abraham Sperling's short bio of Sidis, and Dan Mahony's annotated bibliography of Sidis's writings and news articles about him.

His general theory of the phenomena of the universe, presented in The Animate and the Inanimate, is online here. Recently an army of scientists has been advancing on the dark matter predicted to exist in this book. Soon they will discover that: dark matter consists of dark stars THAT ARE HOT BUT DO NOT EMIT LIGHT.


"We have seen that the structure of the universe, according to the theory of reversibility, is that it consists of irregularly shaped sections, alternately positive and negative. In the positive sections all heated bodies give out radiant energy, according to the second law of thermodynamics. In the negative sections, on the contrary, hot bodies, instead of giving out light or other radiant energy, would tend to absorb it and convert it almost entirely into heat, thus heating themselves up with light received from outside sources. This is in strict accord with the reversal of the second law of thermodynamics."The Animate and the Inanimate, Chap. XIV




The shapes of the parallelopiped sections are altered by harmonics:

" ... either the medium pair of faces is caved in, and the largest and smallest bulged out somewhat less; or the largest and smallest pairs of faces are caved in slightly, and the medium pair of faces extremely bulged out."The Animate and the Inanimate, Chap. XII

" ... the negative sections must be completely surrounded by positive sections and must therefore be finite in all directions. By reversing this (since we have seen that all physical laws are reversible), it follows that any positive section must also be finite in all directions, and be completely surrounded by negative sections. ... We thus find the universe to be ... a sort of three-dimensional checkerboard, the positive spaces counting as white (giving out light), and the negative spaces as black (absorbing light)."The Animate and the Inanimate, Chap. XII


This diagram  from BICEP2 is intended to represent the "first tremors of the Big Bang," but it illustrates well the Sidis Model. The blue areas represent the negative dark-matter sections, the red the positive ordinary-matter sections. And we see each type surrounding the other as Sidis predicted.

A dozen or so visualizations of dark matter (blue) and ordinary matter (red from the orbiting observatories can be found in THE DARK STAR GALAXY DIGEST.



"Our previous consideration on the production of radiant energy from the stars indicates that such production of radiant energy is only possible where the second law of thermodynamics is followed, that is, in a positive section of the universe. In a negative section of the universe the reverse process must take place; namely, space is full of radiant energy, presumably produced in the positive section of space, and the stars use this radiant energy to build up a higher level of heat. All radiant energy in that section of space would tend to be absorbed by the stars, which would thus constitute perfectly black bodies; and very little radiant energy would be produced in that section of space, but would mostly come from beyond the boundary surface. ... If we were on the positive side, as seems to be the case, then we could not see beyond such surface, though we might easily have gravitational or other evidence of bodies existing beyond that surface."The Animate and the Inanimate, Chap. XII


Sidis's 100,000-year history of North America, The Tribes and the States, is as revolutionary as his cosmology. He had learned the language of the wampum—written Native-American history, and then used wampum belts as sources for the first part of this book.


Boris Sidis Archive
Presents here nearly all of the writings of this great psychologist. You'll find here 16 of his 17 books. Find also 44 of his 57 scientific-journal and popular-magazine articles (many of the topics of the other 13 are dealt with in his books); 22 reviews of 13 of his works; and, we assume, most available biographical material.

He starts out noticing something remarkable about the laws of physics:
"Among the physical laws it is a general characteristic that there is reversibility in time; that is, should the whole universe trace back the various positions that bodies in it have passed through in a given interval of time, but in the reverse order to that in which these positions actually occurred, then the universe, in this imaginary case, would still obey the same laws." "If any physical law is true, its reverse must also be true." Astronomers have recently found dark galaxies predicted to exist in this book. Soon they will discover the dark stars therein—also predicted by Sidis.



100,000-Year History of North America
"The weaving of wampum belts was a sort of writing by means of belts of colored beads, in which the various designs of beads denoted different ideas according to a definitely accepted system, which could be read by anyone acquainted with wampum language, irrespective of what the spoken language was. Records and treaties were kept in this manner, and individuals could write letters to one another in this way."



transferstitlepage.jpg (14230 bytes) "This book is a description of what is, so far as the Author is aware, a new kind of hobby, but one which seems on the face of it to be as reasonable, as interesting, and as instructive, as any other sort of collection fad (Introduction)."

The media industry, believing that this was his only book, proclaimed it evidence that Sidis had "burned out." But Notes on the Collection of Transfers is taxonomy Aristotelian in nature, and preserves the entire American trolley-car system for study.

Dr. Sperling's letter mentions a book on philology, and another on anthropology. Elsewhere Sperling wrote: "What the journalists did not report, and perhaps did not know, was that during all the years of his obscure employments he was writing original treatises on history, government, economics and political affairs. In a visit to his mother's home I was permitted to see the contents of a trunkful of original manuscript material that Bill Sidis composed (Psychology for the Millions)."


peacepath.gif (127895 bytes) The Peace Path [Fragment] Sidis wrote in a letter: "I am now writing something that I am entitling The Peace Path, on the old courier system and the many ramifications of its consequences in modern life. It seems to be rapidly developing toward book length, and it seems to have interested the few people who have had a chance to read as much of the manuscript as I have gotten ready so far."―1943.


Re guide books to the local transportation systems of Boston and the District of Columbia. "Several volumes, including two for the Boston area and one for the District of Columbia, are now ready to go to the printer, and several more are almost ready."  "We know of an unpublished guide book that has complete local transit and street-number information, as well as adequate maps; but it is no good to visitors as long as it remains unpublished." ... "According to an unpublished Boston guide-book .... "

Bending the Twig (1910)
Written by a family friend. Quotes Boris Sidis, his father, extensively on WJ's early education, e.g., "My boy plays―plays with his toys, and plays with his books. And that is the key to the whole situation. Get the child so interested in study that study will truly be play." "Dr. Sidis believed that, if properly manipulated, the method of education through play might be extended to subjects not taught in the kindergarten―that, in fact, a child might be led to undertake and continue the study of any subject provided it were made sufficiently interesting to him."

"The intimate details of private life are not entitled to an absolute immunity from the prying of the press, and a limited scrutiny may be had of the private life of any person who has achieved, or has had thrust upon him, the questionable and indefinable status of a 'public figure'."

Shirley Smith's Letter to the Editor (1944)
"Sidis had plenty of loyal friends. All of them found his ideas stimulating and his personality likable."
