  6. I never realized there was so much variation in wine's alcohol content. The range varies from almost 16% to just below 9%. 🤯

Other environmental factors include #temperature, light and #moisture levels, he said. The #public can visit trees.sg to find out where #flowering #trees can be seen"

    Wenn Variabilität auf 100 % Auslastung trifft, explodieren die Wartezeiten – selbst kleine Störungen bringen das System zum Stillstand. Nicht die Variabilität ist das Problem, sondern Systeme ohne Puffer: Wer ohne Slack plant, plant den Stillstand.

  19. Embrace the uncertainty

    Ever since Werner Heisenberg formulated the uncertainty principle, physics has been grappling with the unsettling realization that the universe does not function like clockwork—a metaphor Newton introduced and which held sway for centuries. In a world where predictability and uncertainty intertwine, interpretations range from die-hard determinists, who reject quantum events despite the mounting evidence, to more esoteric merchants of doubt who exploit the ambiguity.

    If Werner Heisenberg […]

  20. In case anyone's keeping score, the idea that JFETs have hugely variable properties and that this problem cannot be - or at least has not been - fixed with different design or manufacturing practices, this batch showed it pretty clearly to me.

    20 J113s, minus 1 fake, equals 19 devices. I measured the Vgs / pinch-off voltage and the Id / drain current in my test rig. The result?

    6 very distinct bins with between 2 and 6 devices in each. Vgs overall varied from (-) 1.30 V to 2.11 V (variance is 38% of the larger value, or 62% of the smaller...), and Id from 5.7 mA to 12.8 mA, a spread of 125% (!) of the smaller value.

    No wonder so many JFET circuits just don't work if you don't hand-match the devices.

  25. A quotation from John Adams

    The Stream of Life sometimes glides smoothly on, through flowry meadows and enamell’d planes. At other times it draggs a winding reluctant Course through offensive Boggs and dismal gloomy Swamps. The same road now leads us thro’ a spacious Country fraught with evry delightful object, Then plunges us at once, into miry Sloughs, or stops our passage with craggy and inaccessible mountains. The free roving Songster of the forest, now rambles unconfin’d, and hopps from Spray to Spray but the next hour perhaps he alights to pick the scattered Grain and is entangled in the Snare. The Ship, which, wafted by a favourable gale, sails prosperously upon the peaceful Surface, by a sudden Change of weather may be tossed by the Tempest, and driven by furious, opposite winds, upon rocks or quicksands. In short nothing in this world enjoys a constant Series of Joy and prosperity.

    John Adams (1735-1826) American lawyer, Founding Father, statesman, US President (1797-1801)
    Diary (1756-03-27)

  32. Centuries ago, I published a manuscript on BioRχiv about the love/hate relationship between variability and robustness in embryogenesis.

    And now, it's published in Science! I am so proud 🥳

    science.org/doi/10.1126/scienc

    We went through three (3!) rounds of revisions. Although we did not change a comma in the abstract, the revisions improved the quality of the work very much (we nearly doubled the sample size and added an entire figure).

    However, their #variability is challenging for the #electricity system.
