Edward R Dewey and the Case for Cycles

After training as an economist, Edward R Dewey devoted his entire working life to the study of cycles. This was because, following the 1929 crash and resulting depression,  he found that cycles were more useful for predicting economic events than any amount of economic theory that he had learned.

Some of the fundamental empirical laws of cycles found by Dewey and others over the years were:

  • Certain common cycle periods appear in many seemingly unrelated disciplines.
  • Cycles Synchrony is the observation that cycles of the same period often have the same phase.
  • Cycles harmonic ratios is the observation that the common cycle periods are often related by ratios of 1:2 and 1:3 and their products.
  • Cycles outside the earth are related to cycles on earth. This was a conclusion that he came to reluctantly because at first it sounds like astrology.

These individual observations will often appear in articles about cycles in this blog. In fact, astute observers not aware of these discoveries have often rediscovered parts of these laws for themselves.

For a more detailed explanation of these conclusions, there is no better reference than Dewey’s 1967 paper “The Case for Cycles”: http://www.cyclesresearchinstitute.org/dewey/case_for_cycles.pdf

One thing can be added to the harmonic relationships noted by Dewey. The referenced paper shows cycles arranged in two triangular shapes that meet at one vertex. These shapes and the ratios within them are exactly the same as Pythagoras’ Lambda which was Pythagoras’ way of representing the musical scale. Dewey does not seem to mention anywhere that his table is the same as Pythagoras’ so it is worth mentioning here.

Actually, long after Pythagoras, Galilei, the father of the famous Galileo, suggested that some of the notes in Pythagoras scale were better replaced by ratios that had a 5 in them. So for a major chord rather than having C-E-G be in the ratio 1 : 81/64 : 3/2 Galilei had the simpler 1 : 5/4 : 3/2 or simply 4:5:6. There were debates about these matters, and there are arguments for both. These other than 2 and 3 based ratios are most definitely real however, and can be seen in the ideal piano tuning shown here:

The 12 semitone octave copes well, with ratios involving 2, 3 and 5 but not with 7, 11 and 13 which fall into the cracks as shown here. However 17 and 19 again fit.

About Ray Tomes

Ray's career was in computer software development including system software design, economic modeling, investments. He spent 15 years full time on cycles research and has spoken on cycles and related topics at conferences and seminars around the world. He retired at age 42 to study cycles full time and work out “The Formula for the Universe” and as a result developed the Harmonics Theory as an explanation for observed patterns of cycles and structure of the Universe. His current project is the development of CATS (Cycles Analysis & Time Series) software, and collecting and organizing large quantities of time series data and analyzing this data to test and confirm Dewey's findings in an organized way. Interested in all aspects of cycles especially climate change and causes.

    In 1952 Dewey penned an article titled; “What Are Cycles?” In the article he commented on the rythmicity of women’s menstrual cycles. Dewey stated that “Cycles are not the whole answer, but on the other hand they are indispensable in attempting to arrive at the whole answer. Cycles remind me of women. Women are not perfect (with individual exceptions, I hasten to add). But they are the best thing so far invented for the purpose. Until something better comes along we will have to make shift with them as they are – or else miss the values they have to offer. Let’s find out all we can about them!”

    Arch Crawford in his latest interview stated that Dewey cycles are fractions or multiples (harmonics) of cycles of planets that go around earth. Has there been detailed studies shedding light on this matter.

  3. Ray Tomes says:

    Hi Hass, Dewey was aware that some of the periods found are close to planetary cycles. He did publish an article with a list of planetary harmonics. There are quite a few other people that also noticed this. But not all common cycles fit planetary cycles. Dewey wrote an article “A Key to Sunspot-Planetary Relationship” in Cycles, October 1968.

    My analysis using Kotov’s method of commensurability of periods does show that common cycles and planetary cycles have considerable similarity. Specifically, taking all the planetary periods and synodic periods produces the common cycles as fractions and multiples of these. This is an unbiased mathematical test.

  4. Hass Tavakoli says:

    Hi Ray, would you please be kind enough,if possible, to post the above two articles, so we can read them.
    I have four volumes of Dewey, but I cannot find the above articles in the classics library collection, nor in the selected writings book.

    Additionally, it was mentioned in one of the interviews that planetary alignments/cycles correspond to
    18.6 year cycle and its fractals in time. Dewey’s table, and yours show the main base to be around
    17.75 or so. Any comments on this observation is fully appreciated. Thanx.
