Há livros que nos marcam de forma definitiva porque nos tocam a alma da nossa essência. Jamais esquecerei a história da carpa contada por um ser magnifico, como o são todos os que facultam os seus conhecimentos para que os demais elevem os seus horizontes e tenham gosto pela ciência. Assim é Michio Kaku, transporta-nos a viagens que ultrapassam as barreiras dos nossos sentidos com visões audazes.
E por acaso não é comum dizer-se ‘A sorte protege os audazes’?. Acontece que não é a sorte, é o amago da vida.
Marcou-me a história da carpa e do lago, não resisto a transcrevê-la na lingua original, porque quem conta um conto acrescenta um ponto.
‘Living their entire lives in the shallow pond, the carp would believe that their universe consisted of the murky water and the lilies. Spending most of their time foraging on the bottom of the pond, they would only dimly aware that an alien world could exist above the surface. The nature of my world was beyond their comprehension. I was intrigued that I could sit only a few inches from the carp, yet be separated from them by an immense chasm. The carp and I spent our lives in two distinct universes, never entering each other’s world, yet were separated by only the thinnest barrier, the water’s surface.
I once imagined that there may be carp ‘scientist’ living among the fish. They would, I thought, scoff at any fish who proposed that a parallel world could exist just above the lilies. To a carp ‘scientist’ the only things that were real were what the fish could see or touch. The pond was everything. An unseen world beyond the pond made no scientific sense.
Once I caught in a rainstorm. I noticed that the pond’s surface was bombarded by thousands of tiny raindrops. The pond’s surface became turbulent, and the water lilies were being pushed in all directions by water waves. Taking shelter from the wind and the rain, I wondered how all this appeared to the carp. To them, the water lilies would appear to be moving around by themselves, without anything pushing them. Since the water they lived in would appear invisible, much like the air and the space around us, they would be baffled that the water lillies could move around by themselves.
Their ‘scientists’ I imagined, would concoct a clever invention called a force in order to hide their ignorance. Unable to comprehend that there could be waves on the unseen surface, they would conclude that lilies could move without being touched because a mysterious, invisible entity called a force acted between them. They might give this illusion impressive, lofty names (such as action-at-a-distance, or the abillity of the lilies to move without anything touching them).
Once I imagined what would happen if I reached down and lifted one of the carp scientists out of the pond. Before I threw him back into the water, he might wiggle furiously as I examined him. I wondered how this would appear to the rest of the carp. To them, it would be a truly unsettling event. They would first notice that one of their scientists had disappeared from their universe. Simply vanished, without leaving a trace. Wherever they would look, there would be no evidence of the missing carp in their universe. Then, seconds later, when I threw him back into the pond, the scientist would abruptly reappear out of nowhere. To the other carp, it would appear that a miracle had happened.
After collecting his wits, the scientist would tell a trully amazing story. “without warning” , he could say, “I was somehow lifted out of the universe (the pond) and hurled into a mysterious nether world, with blinding lights and strangely shaped objects that I had never seen before. The strangest of all was the creature who held me prisoner , who did not resemble a fish in the slightest. I was shocked to see that it had no fins whatsoever, but nevertheless could move without them. It struck me that the familiar laws of nature no longer applied in this nether world. Then just as suddenly, I found myself thrown back into our universe”. ‘

Gosto da divulgação cientifica, daquela que começa na base que todos conhecemos para a seguir nos catapultar aos meandros dos raciocinios que nos permitem distinguir das restantes formas de vida, e talvez despertar em alguns o interesse que suplanta letargias crónicas.
É um prazer sublime a leitura de “universo elegante” e a “tecido do cosmos” de Brian Greene, pagina a pagina sentimos a beleza das leis que regem o nosso planeta, o nosso universo até aos limites do conhecimento actual
Numa entrevista a Carlos Fiolhais dizia ele que o português vive muito o sebastianismo e o aguardar de soluções, mas há que tomar parte activa, o problema nacional é acima de tudo um problema cultural.
E quanto a crise? Responde muito do que desce sobe e vai ter o efeito positivo de nos tornar a todos mais racionais e quiçá mais unos.
É isso que eu acredito
