Non sapete cosa fare in questa domenica uggiosa? Ecco una svolta che vi farà passare un paio di minuti... poi al resto della giornata pensateci voi, mica posso pensare a tutto io...
Come scritto nel titolo del filmato, dovete prima leggere le istruzioni. Eccole:
Instructions: Keep your eyes fixed on the small white mark in the center. At first, the ring is stationary and it's easy to tell that the dots are changing. A few seconds later, the ring begins to rotate and the dots suddenly appear to stop changing. (Or, more precisely, they appear to change much less than when the dots are motionless.)
But play the movie again, this time looking directly at one of the dots and following it as the ring rotates. You will see that, in fact, the dots had been changing at the same rate the whole time, even during the rotation—you just didn't notice it. This failure to detect that moving objects are changing is silencing.
The full set of demos, and a reprint of the paper, is available athttp://bit.ly/cAVMEU
Per chi non conosce l'idioma britannico: beh, siamo nel 2011 e tocca che ve lo imparate.
