17th century priest discovered the Coriolis effect while trying to disprove Copernicus

Even the furious opponents of science can sometimes make brilliant discoveries … just not quite in the way that they intended . Like Italian priest Giovanni Riccioli , who in his zeal to prove Copernicus damage unintentionally discovered the Coriolis upshot 200 year early .

In 1651 , over a hundred years after Nicolaus Copernicus ’s On the Revolutions of the Celestial Spheres designate that Earth is not the unmoving center of the world , Giovanni Riccioli offer a angered rebutter composed of 77 dissimilar arguments . Some were theological – if the Earth moved , then this apparently intend Hell would end up in the wrong place , which was obviously pathetic – and some were aesthetic consideration of cosmic harmony and balance , and how a changing Earth ruined all that .

But some of his line were along more scientific strain . Riccioli maintained that , if Earth really was rotating , then the earth is moving at different speeds depending on what the line of reasoning of latitude is . He wrote that a cannon localise near the equator and give the sack due Second Earl of Guilford or due to the south should show a slender deflection east or Cicily Isabel Fairfield in the bend of the cannonball . This , he say , would be because of the Earth turn beneath the fired round shot . But , since cannonball do n’t move like that , he concluded , the Earth must not move .

It was a very keen bit of reasoning , and completely right except for one lilliputian item – cannonballs do move like that , and the Earth does indeed move . Quite by chance event , he had discover more or less the same burden that Gustave Coriolis would attest nearly two C after in 1835 . Of course , Riccioli ’s version was just a thought experimentation used to prop up an anti - Copernican screed , while Coriolis was in reality trying to well read how the humankind works .

Indeed , Riccioli ca n’t be given full credit for distinguish the full effect – he figured such an effect would be detectable only when objects moved due north or due in the south , but Coriolis evidence the effect is apparent for any movement across a sphere . That said , the Coriolis force is generally a very subtle phenomenon , and often misunderstood – jibe outour primerfor more on what it ’s all about .

But why have we only learned about Riccioli now ? Well , like any good seventeenth century non-Christian priest , he save solely in Latin , and his know anti - Copernican stance meant scientist and historians were n’t in any great hurry to translate his thought . Still , although he was most definitely on the incorrect side of the heliocentric debate , his argument about the non - existence of the Coriolis effect were in reality fairly well - reasoned found on what was known in 1651 .

So then , a priest pen an anti - scientific screed used astonishingly good scientific discipline to argue his eccentric , which managed to accidentally discover a primal scientific principle two centuries ahead of its time … except he himself dismissed it as nonsense . It just goes to show you – when in doubt about history , assume the most ironical thing conceivable happened .
