    AST SpaceMobile satellites measured far brighter than FCC targets●"Our measurements reveal an average brightness seven times brighter than mitigation targets cited in FCC filings and peaMmastodonScienceSpace Policy7344 min ago

    Astronomers report new measurements showing AST SpaceMobile satellites average seven times the brightness of mitigation targets cited in the company's FCC filings, with peak brightness over 200 times the International Astronomical Union's recommended limit of magnitude 7. The findings intensify concerns about the planned deployment of further satellites and their impact on astronomical observations, renewing debate over regulation of megaconstellations and light pollution.

    Tufte's 'lie factor' revived to critique distorted charts●-> représentation d'une évolution sans tenir compte de toutes les proportions = Indice de mensonge de Tufte " La représeMmastodonLifeEducation120 h ago

    Edward Tufte's 'lie factor' concept is back in circulation among French-speaking readers. The idea, drawn from his classic book 'The Visual Display of Quantitative Information', holds that any graphic showing an evolution must keep physical magnitudes proportional to the numbers represented, otherwise the chart lies. Readers are quoting his rule that representation of numbers by measured quantities should be directly proportional, a principle often violated in media and business graphics.
