The 12-Hour Biological Rhythm Internal Clocks: Chronobiologists have discovered that thousands of genes and physiological processes—such as core body temperature, hormone levels, blood pressure, and alertness—follow a dual oscillation, peaking and dipping every 12 hours rather than just once a day...

The Potato That Could Forecast the Weather: Frank A. Brown Jr.'s Exogenous Clock If you've spent any time in cycles research, you've run into the standard story of biological rhythms: every organism carries its own internal clock, a self-winding mechanism ticking away independent of the outside wor...

The 20-year yield hits the cycle model's loudest topping alarm just as Warsh argues rates higher - Lar von Thienen August 30 (shown with permission) Friday belonged to Warsh. The Fed chair used his Jackson Hole speech to praise the labor market and to make clear that better inflation prints have no...

The 26–27-Million-Year Cycle: Extinctions, Volcanism, and a Contested Cause Overview Where the 2.4 Myr and 405 kyr eccentricity cycles are grounded in exact celestial mechanics, the 26–27 Myr cycle sits at the opposite end of the evidentiary spectrum: a periodicity detected purely statistically, i...

The 2.4-Million-Year Eccentricity Grand Cycle — and Its Relationship to the 405-kyr "Metronome" Overview Of all the long geological cycles surveyed for periods over a million years, the 2.4 Myr eccentricity grand cycle stands apart: it is the one whose mechanism is understood exactly, from first p...

A very useful App for cycles researchers Another very useful App

Quite often I find graphs published in articles but I can not find the data that the graph is based on. It can be very frustrating. So I made this app to allow the graphic to be dropped into it and after a few clicks on the scales and such it gives you a CSV file of the data in the graph. Here are t...

The following is an app for calculating Kotov' Method for communality of a set of values. You just load it into a browser and then past or type in the list of values to the window, select the range over which you want the spectrum and press compute spectrum. It is preloaded with the Planets distance...

A. E. Douglass: Tree Rings, Sunspots, and the Birth of Dendrochronology Compiled from the Foundation for the Study of Cycles archive (Cycles Magazine, vols. 1950–1957) Who He Was The archive gives a clear, specific origin story for Douglass, drawn from a secondary source the Foundation reviewed ...

Raymond H. Wheeler: Climate, War, and the Rise and Fall of Civilizations Compiled from the Foundation for the Study of Cycles archive (Cycles Magazine, vols. 1950–1957) Who He Was Unlike Brunt, Beveridge, or Playfair, the archive gives Wheeler a real institutional biography — he wasn't a distant...

Sir William Beveridge and the 900-Year Wheat Price Study Compiled from the Foundation for the Study of Cycles archive (Cycles Magazine, vols. 1950–1957) Who He Was, According to the Archive The archive gives Beveridge slightly more formal treatment than it gave Brunt — he's consistently referred...

William Playfair: The Forgotten Predecessor Compiled from the Foundation for the Study of Cycles archive (Cycles Magazine, vols. 1950–1957) A Note Before You Start Unlike the Brunt entry, this one is thin by necessity — Playfair appears in the archive via a single reader's letter, plus one index...

Notable Contributors to Cycles Research Found in Cycles Magazine (Foundation for the Study of Cycles), Volumes 1–8, 1950–1957 Important scope note: This scan covers only the 8 volumes currently loaded in this project (1950–1957). You mentioned having 46 volumes in total — this is therefore a parti...

David Brunt and the Study of Weather Cycles Compiled from the Foundation for the Study of Cycles archive (Cycles — A Monthly Report / Cycle Magazine, vols. 1950–1955) Who He Was Sir David Brunt appears in these pages as "an Englishman" — the archive gives no further biographical detail beyond hi...
