A meta-analysis of the long-term field trials behind farmland carbon claims, and why the depth you dig to changes the answer enough to matter for anybody selling an offset.

    How Anybody Knows How Old Anything Is

    Almost every date you have ever read about the past came out of one of seven or eight methods, and not one of those methods deserves to be trusted on its own. Tree rings and lake muds and ice layers count years directly, one at a time, while radiocarbon, potassium-argon and uranium-lead measure atoms instead, each covering a different slice of time. The whole structure becomes believable because the slices overlap ,

    Counting Every Word in Fifty Books to Test a Law Nobody Can Explain

    Zipf's law says that if you rank the words of a text by frequency, the count at rank (r) falls off like (r^{-a}) with (a) near 1. We tokenised fifty public-domain books from Project Gutenberg spanning fourteen languages and about 2,350 years, from a Greek tragedy to a 1925 American novel, and fit both a pure Zipf law and a shifted ZipfMandelbrot form by exact maximum likelihood, never by regression on a log-log

    When the First Digit Test Works and When It Accuses the Innocent

    Benford's law says the leading digit of many collections of real numbers is 1 far more often than 9, following (P(d) = log_{10}(1+1/d)), and it is now a standard test for cooked books, rigged elections and fabricated data. We put eight genuinely public datasets through the test, chosen for having nothing in common: country populations, CODATA physical constants, every FDIC-insured bank's total assets and total dep

    Does Metabolism Really Scale to the Three Quarter Power

    Kleiber's law says metabolic rate scales as body mass to the three quarter power. Rubner's older surface argument says two thirds. The gap between them is ( frac{1}{12} = 0.0833), and people have been arguing about it since 1932. We took one published compilation, AnAge Build 15, retrieved 14 September 2026, pulled out every species carrying both a body mass and a metabolic rate, and fitted the exponent by two met

    How Much Carbon Can Farmland Actually Hold? A Review of the Field Trial Evidence

    Farmers are being offered money to store carbon in their soil, the practices on the menu being no-till, cover cropping and residue retention, and the rates written into contracts usually sit somewhere near half a tonne of carbon per hectare per year. We went looking for where that number comes from. Screening 22 published syntheses and long-term trial reports, we could extract 12 effect sizes carrying usable uncertai
