Sempre digo que “F\u00edsica Qu\u00e2ntica” virou uma palavra-coringa para se falar de coisas que n\u00e3o se faz id\u00e9ia do que s\u00e3o. “I don`t know how it works, but it’s surely quantum!”<\/strong>. Com o lan\u00e7amentos de “filmes” (seria mais preciso cham\u00e1-los de mockumentaries, <\/em>mas…), como Quem Somos N\u00f3s e O Segredo, a F\u00edsica Qu\u00e2ntica virou sin\u00f4nimo de doideira m\u00edstica. Mas n\u00e3o s\u00f3 isso. Essa “populariza\u00e7\u00e3o” fez com que qualquer coisa que envolvesse probabilidades e incertezas fosse automaticamente atribu\u00edda \u00e0 F\u00edsica Qu\u00e2ntica.<\/p>\n

Na Inglaterra, uma poeta resolveu criar poemas constru\u00eddos aleatoriamente com a ajuda de ovelhas. Cada ovelha foi pintada com uma palavra e, de acordo com os ritmos de movimento e descanso dos animais, os poemas s\u00e3o escritos. Da BBC<\/a> [1]<\/strong>:<\/p>\n

A North East writer has been given a grant of \u00a32,000 to use sheep to create random poems, which also utilise the deepest workings of the universe.<\/p>\n

The money has been provided by Northern Arts for Valerie Laws to create a new form of “random” literature.<\/p>\n

Each of the animals has a word from a poem written on their backs and as they wander about the words take a new poetic form each time they come to rest.<\/p>\n

But the exercise is not just an attempt to create living poems, it is also, according to the poet, an exercise in quantum mechanics.<\/p>\n

The animals being sprayed belong to farmer Donald Slater of Whitehouse Farm Centre, Morpeth, in Northumberland.<\/p>\n

Mrs Laws, 48, said: “I like the idea of using living sheep to create a living poem, and creating new work as they move around.
\n“Quantum mechanics is a branch of physics which a lot of people find hard to understand, as it seems to go against common sense.
\n“Randomness and uncertainty is at the centre of how the universe is put together, and is quite difficult for us as humans who rely on order.
\n“So I decided to explore randomness and some of the principles of quantum mechanics, through poetry, using the medium of sheep.”<\/strong>
\nMrs Laws created a poem for the project, based on the traditional Japanese haiku form of poetry.
\nEach sheep had a word from the poem sprayed on their back, and when they came to rest a new text was created.
\nFarmer Donald Slater said: “After last year’s devastation (of foot-and-mouth) we all needed cheering up and this might just do it.”
\nA spokesman for Northern Arts called the scheme “an exciting fusion of poetry and quantum physics”.
\nOne of the poems created by the sheep reads:
\nWarm drift, graze gentle, White below the sky, Soft sheep, mirrors, Snow clouds.<\/p><\/blockquote>\n

Na parte que grifei l\u00ea-se:<\/p>\n

“Ent\u00e3o eu decidi explorar a aleatoriedade e alguns princ\u00edpios da Mec\u00e2nica Qu\u00e2ntica, atrav\u00e9s da poesia, usando as ovelhas como meio.”<\/p>\n<\/blockquote>\n

Explora\u00e7\u00e3o de aleatoriedade pode at\u00e9 ser, mas est\u00e1 longe de se relacionar de qualquer maneira, mesmo metaforicamente, com Mec\u00e2nica Qu\u00e2ntica. At\u00e9 porque todo mundo sabe que os \u00fanicos animais sujeitos a efeitos qu\u00e2nticos s\u00e3o os gatos.<\/em><\/p>\n

De outro artigo<\/a> [2]<\/strong>, dessa vez sobre esportes:<\/p>\n

“Every year, each team has just as much chance to win every game as it does to lose every game,” Morris said. “It’s called quantum<\/span> physics and the laws of chance and probability. <\/strong>Thirty-one other teams have already gone down in flames. But the Titans have a 50-50 chance each week to win, and those chances never improve beyond 50-50, because on any given Sunday, anyone can win. As long as you keep that in perspective, you have a chance to win every game.”<\/p>\n<\/blockquote>\n

A vit\u00f3ria de um time est\u00e1 relacionada com acaso e probabilidades mas nem um pouco com F\u00edsica Qu\u00e2ntica. Bem, h\u00e1 alguns casos de Tunelamento de times de futebol brasileiros para a primeira divis\u00e3o quando deveriam ser rebaixados, mas isso \u00e9 totalmente<\/em> metaf\u00f3rico.<\/p>\n

Mas n\u00e3o podemos rir apenas da ignor\u00e2ncia estrangeira. Aqui vai uma p\u00e9rola de uma atriz brasileira<\/a> [3]<\/strong>. N\u00e3o \u00e9 exatamente sobre F\u00edsica Qu\u00e2ntica, mas \u00e9 prov\u00e1vel fruto da leitura desses livros mistic\u00f3ides qu\u00e2nticos de gosto duvidoso:<\/p>\n

\n

Quais s\u00e3o os outros? <\/strong>A amorosa reprodu\u00e7\u00e3o. Quando voc\u00ea gera um filho amorosamente, voc\u00ea se sente Deus, sabe? Voc\u00ea \u00e9 m\u00e3e?<\/p>\n

N\u00e3o. <\/strong>As pessoas n\u00e3o querem mais ser m\u00e3e. Se voc\u00ea for, vai ver. Vai entender o lado divino do ser humano e vai passar para uma segunda dimens\u00e3o. Os f\u00edsicos falam isso, n\u00e3o \u00e9?<\/em><\/p><\/blockquote>\n

Pois \u00e9 caro leitor, voc\u00ea era uma Reta e nem sabia disso. Vai ver \u00e9 algum tipo de met\u00e1fora para o quanto as mulheres engordam depois que tem filhos. Sei l\u00e1.<\/p>\n

\u00c9 claro que existem utiliza\u00e7\u00f5es e cita\u00e7\u00f5es bem piores, principalmente as vindas dos meios “intelectuais” (Qwa Qwa Qwa). Mais dessas coisas ficar\u00e3o para outra hora. O que j\u00e1 ouvi de Psic\u00f3logo (ah, como eles gostam do Quem Somos N\u00f3s…) e “Cientista” Social falando besteira em nome da F\u00edsica Qu\u00e2ntica, Teoria do Caos, Fractais…<\/p>\n
