pi&ugrave; importante di Huygens, considerata una delle tre opere fondamentali sulla meccanica del XVII secolo assieme ai <em>Discorsi </em>di Galileo (1638) e ai <em>Principia </em>di Newton (1687). Christiaan Huygens (1629-1695) &egrave; stato un matematico, astronomo e fisico olandese, fra i protagonisti della rivoluzione scientifica; la sua reputazione era cos&igrave; grande che, nel 1665, Luigi XIV, gli offr&igrave; una pensione per vivere a Parigi. Fu probabilmente questo motivo a spingere Huygens a dedicargli l'<em>Horologium</em>, nonostante a quel tempo i Paesi Bassi fossero in guerra con la Francia. Contenente la prima analisi matematica del moto del pendolo e un trattato generale sulla dinamica dei corpi in movimento, l'<em>Horologium</em> "fu l'opera pi&ugrave; originale di questo genere dai <em>Discorsi </em>di Galileo" (PMM). Huygens aveva costruito il primo orologio a pendolo nel 1657, concetto gi&agrave; ipotizzato da Galileo che aveva notato l'isocronismo del pendolo, ovvero la sua propriet&agrave; di oscillare in un tempo costante, indipendentemente dall'ampiezza dell'oscillazione. L'idea offriva una brillante soluzione al problema all&rsquo;epoca molto dibattuto soprattutto in Olanda di tenere il tempo a bordo delle navi (cosa essenziale per determinare la longitudine). L'invenzione di Huygens ebbe un enorme successo: l&rsquo;anno successivo, pendoli furono montati persino alle torri dell&rsquo;orologio di Scheveningen e Utrecht. Il suo studio sulla forza centrifuga fu "utilizzato da Newton nella sua determinazione della gravitazione universale" (Norman). <span style="font-variant: small-caps;">Dibner</span>, <em>Heralds</em>, 145; <span style="font-variant: small-caps;">Grolier/Horblit</span>, 53; <span style="font-variant: small-caps;">Norman</span>, 1137; PMM 154.</p>
