Willett: chi propose davvero l\u2019ora legale?<\/h3>\n<p>Per arrivare alle vere proposte di modifica stagionale dell\u2019orario bisogna aspettare pi\u00f9 di un secolo. Nel<strong> 1895<\/strong> il neozelandese<strong> George Vernon Hudson<\/strong>, entomologo appassionato di astronomia, presenta una proposta per <strong>adattare gli orari alle ore di luce disponibili<\/strong>. Il suo obiettivo \u00e8 sfruttare meglio le giornate estive, riducendo il ricorso all\u2019illuminazione artificiale.<\/p>\n<p>Nel <strong>1907<\/strong> \u00e8 invece l\u2019inglese<strong> William Willett<\/strong> a rilanciare l\u2019idea con l\u2019opuscolo <em>The Waste of Daylight<\/em>, (Lo spreco della luce diurna). Willett immagina di <strong>spostare gradualmente le lancette in primavera e di riportarle indietro in autunno<\/strong>, cos\u00ec da regalare pi\u00f9 luce alle serate. Il principio dell\u2019ora legale moderna prende forma attraverso queste proposte, non nella lettera scherzosa di Franklin. Attribuire a quest\u2019ultimo l\u2019invenzione vera e propria \u00e8 quindi una semplificazione storica: la sua intuizione satirica anticipa il tema, ma non equivale al sistema che conosciamo oggi.<\/p>\n<blockquote><p><strong>Leggi anche:<\/strong> <a href=\"https:\/\/www.frasicelebri.it\/news\/foglie-cadono-senti-piu-fragile-poesia-autunno-rilke-malinconia\/\" target=\"_blank\" rel=\"noopener\">Le foglie cadono e ti senti pi\u00f9 fragile: la poesia d\u2019autunno di Rilke che spiega questa malinconia e come attraversarla<\/a><\/p><\/blockquote>\n<h3>La lezione di Benjamin Franklin: il tempo non si cambia con le lancette<\/h3>\n<p>La storia della lettera del 1784 ci ricorda che, a volte, anche le idee pi\u00f9 serie nascono da una battuta e che non tutto ci\u00f2 che viene attribuito a un grande personaggio corrisponde alla realt\u00e0. <strong>Benjamin Franklin non invent\u00f2 l\u2019ora legale<\/strong>, ma con la sua ironia ci lasci\u00f2 una riflessione ancora attuale sul rapporto tra luce, abitudini e risparmio. Oggi, a distanza di oltre due secoli, continuiamo a discutere se sia meglio guadagnare luce la sera o ritrovarla al mattino.<\/p>\n<p>Io non ho dubbi: preferisco l\u2019ora solare, con i suoi ritmi pi\u00f9 naturali e quell\u2019ora di sonno in pi\u00f9 che, diciamolo, non si rifiuta mai. E se Franklin voleva convincere i parigini ad alzarsi all\u2019alba a colpi di cannone, io preferisco decisamente un risveglio tranquillo, magari con un caff\u00e8 caldo. La storia ci insegna tante cose, ma una almeno \u00e8 certa: per svegliarmi prima, non basterebbe neppure la Rivoluzione francese!<\/p>\n<blockquote><p><strong>Leggi anche: <\/strong><a href=\"https:\/\/www.frasicelebri.it\/news\/seneca-arte-rallentare-primi-malanni-autunno-alleato-accanto-vaccino-antinfluenzale\/\" target=\"_blank\" rel=\"noopener\">Seneca e l\u2019arte di rallentare con i primi malanni d\u2019autunno: smetti di trattare la guarigione come tempo sprecato<\/a><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Nella notte tra il 24 e il 25 ottobre torneremo all\u2019ora solare: le lancette si sposteranno indietro di un\u2019ora e, almeno sulla carta, guadagneremo sessanta &#8230; <a title=\"Domenica torna l\u2019ora solare: cosa ha inventato davvero Benjamin Franklin?
