Pois eu também desconhecia totalmente a existência deste simples brinquedo de nome esquisito!
Parece que servia para horas e horas de ilusão...perdão, de diversão!
Aqui fica a explicação:
Thaumatrope....anyone knew this?
Well, i totally didn't know any about this simple toy with a weird name!
It seems like it wold last for hours and hours of illusion....pardon!amusement!
Here's the explanation:
"Inventado em 1824, por Peter Mark Roget que apresentou um artigo à Royal Society de Londres intitulado The Persistence of Vision with Regard to Moving Objects onde abordava e discutia uma certa sensação ilusória de se enxergar uma roda (de carruagem) rodar ao contrário, durante seu movimento normal de rotação. Por muitos anos a teoria da Persistência Retiniana comandou o campo da neurofisiologia e neurologia acerca do processo de percepção das imagens. Desde as primeiras décadas do século XX, pesquisas mais apuradas comprovaram que essa teoria, apesar de lógica, não explica satisfatoriamente os processos de formação da imagem no nosso cérebro. Atualmente, a ciência, cita os efeitos phi (Φ) e beta (β) como os mecanismos responsáveis pelo processo de formação das imagens em movimento."
"A thaumatrope is a toy that was popular in the 19th century. A disk with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to blend into one due to the persistence of vision.
Examples of common thaumatrope pictures include a bare tree on one side of the disk, and its leaves on the other, or a bird on one side and a cage on the other. They often also included riddles or short poems, with one line on each side. Thaumatropes were one of a number of simple, mechanical optical toys that used persistence of vision. They are recognised as important antecedents of cinematography and in particular ofanimation.The coined name translates roughly as "wonder turner", from Ancient Greek: θαῦμα "wonder" and τρόπος "turn".The invention of the thaumatrope is usually credited to either John Ayrton Paris or Peter Mark Roget.Paris used one to demonstrate persistence of vision to the Royal College of Physicians in London in 1824.He based his invention on ideas of theastronomer John Herschel and the geologist William Henry Fitton, and some sources attribute the actual invention to Fitton rather than Paris.Charles Babbage reported being introduced to the concept by Herschel and Fitton.In 2012, it was reported that a prehistoric thaumatrope had been discovered in caves in France, particularly the Chauvet Caves."
