Y es l\u00f3gico: desde el punto de vista cient\u00edfico, este reto es un experimento &#8220;casi imposible&#8221; y con bastante mala idea.<\/p>\n<h3>\u00bfPor qu\u00e9 no se puede atrapar? El secreto del &#8220;muro de los 0,2 segundos&#8221;<\/h3>\n<p>La clave est\u00e1 en nuestro &#8220;tiempo de reacci\u00f3n&#8221;. Para mover el cuerpo en respuesta a algo que vemos, nuestro organismo necesita seguir esta cadena de pasos:<\/p>\n<p>Los ojos (\u00f3rgano sensorial) ven caer el billete (entrada de informaci\u00f3n)<\/p>\n<p>\u2192 La informaci\u00f3n viaja por el nervio \u00f3ptico hasta el cerebro<\/p>\n<p>\u2192 El cerebro decide: &#8220;\u00a1Se ha ca\u00eddo! \u00a1Mueve los dedos!&#8221; y env\u00eda la orden<\/p>\n<p>\u2192 La orden recorre los nervios motores hasta los m\u00fasculos de los dedos<\/p>\n<p>\u2192 Los m\u00fasculos se contraen y, por fin, el dedo se mueve (acci\u00f3n)<\/p>\n<p>Es como jugar al tel\u00e9fono escacharrado dentro de tu propio cuerpo. Se dice que todo este proceso tarda unos 0,2 segundos, incluso en las personas con los reflejos m\u00e1s r\u00e1pidos. Y ahora la pregunta: en esos 0,2 segundos que parecen un suspiro, \u00bfcu\u00e1nto habr\u00e1 ca\u00eddo el billete?<\/p>\n<p>Aqu\u00ed entra en escena la &#8220;ca\u00edda libre&#8221;. Cuando un objeto cae atra\u00eddo por la gravedad, la distancia recorrida es proporcional al cuadrado del tiempo, as\u00ed que crece cada vez m\u00e1s deprisa. En f\u00f3rmula, queda as\u00ed: y=1\/2\u200bgt^2<\/p>\n<p>Si metemos en la f\u00f3rmula el tiempo de reacci\u00f3n, t=0,2 segundos, el resultado es&#8230;<\/p>\n<p style=\"text-align: center;\">y=1\/2\u00d79,8 m\/s2\u00d7(0,2 s)2=0,196 m\u224819,6 cm<\/p>\n<p>\u00a1Nada menos que unos 19,6 cm!

Si esperas a verlo, ya es tarde. Esa es la raz\u00f3n cient\u00edfica por la que no puedes atraparlo.<\/p>\n<h3>\u00bfCu\u00e1l es el l\u00edmite para atraparlo? Hagamos la cuenta al rev\u00e9s<\/h3>\n<p>Ya que estamos, d\u00e9mosle la vuelta al problema. Como los dedos est\u00e1n colocados en el centro del billete, solo podr\u00e1n agarrarlo mientras el billete caiga unos 7,5 cm (la mitad de su longitud). Si despejamos el tiempo en la f\u00f3rmula anterior, podemos calcular cu\u00e1nto tarda en recorrer esa distancia.<\/p>\n<p style=\"text-align: center;\">t=\u221a(2y\/g)=\u221a(2\u00d70,075\u00f79,8)\u22480,12 segundos<\/p>\n<p>O sea, para atrapar el billete tendr\u00edas que haber terminado de cerrar los dedos en menos de 0,12 segundos desde que lo ves caer. Pero el tiempo de reacci\u00f3n humano ronda los 0,2 segundos. Te faltan unos 0,08 segundos. Por mucho empe\u00f1o que le pongas, no hay manera de ganar.<\/p>\n<p>Por cierto, la resistencia del aire es tan peque\u00f1a que apenas afecta al billete. As\u00ed que si pensabas &#8220;como cae revoloteando, quiz\u00e1 vaya m\u00e1s lento&#8221;, lamento decirte que eso casi no cambia el c\u00e1lculo.<\/p>\n<h3>\u00a1Pero si puedes &#8220;predecirlo&#8221;, s\u00ed puedes atraparlo!<\/h3>\n<p>Entonces, \u00bfes imposible ganar? En realidad, hay un truco: &#8220;saber cu\u00e1ndo va a caer&#8221;.<\/p>\n<p>Por ejemplo, \u00bfqu\u00e9 pasar\u00eda si A hiciera una cuenta atr\u00e1s, &#8220;\u00a13, 2, 1, ya!&#8221;, antes de soltar el billete? B ya no reaccionar\u00eda a lo que ve, sino que mover\u00eda los dedos anticip\u00e1ndose, y sus posibilidades de atraparlo se disparar\u00edan. El muro del tiempo de reacci\u00f3n solo existe cuando &#8220;primero ves y luego te mueves&#8221;; no tiene ning\u00fan efecto cuando te mueves &#8220;anticip\u00e1ndote&#8221;.<\/p>\n<p>Si podemos golpear una pelota de b\u00e9isbol o controlar un bal\u00f3n en el f\u00fatbol, es porque nuestro cerebro predice la trayectoria de la pelota que viene volando. Este &#8220;experimento con mala idea&#8221; tambi\u00e9n nos ense\u00f1a la asombrosa capacidad de predicci\u00f3n del cerebro humano.<\/p>\n<h3>El tiempo de reacci\u00f3n en la vida cotidiana<\/h3>\n<p>Cuando hago este experimento en clase, siempre es un \u00e9xito. &#8220;\u00a1Profe, casi lo logro!&#8221;, &#8220;\u00a1A la pr\u00f3xima s\u00ed!&#8221;, dicen todos con los ojos brillantes, pero el resultado es siempre el mismo. Ver las caras de frustraci\u00f3n de los alumnos tambi\u00e9n tiene su gracia.<\/p>\n<p>Este &#8220;tiempo de reacci\u00f3n&#8221; est\u00e1 presente en muchas situaciones de nuestra vida.<\/p>\n<p>Por ejemplo, al conducir. Desde que notas un peligro hasta que pisas el freno, el coche sigue avanzando (es la llamada distancia de reacci\u00f3n). Un coche a 60 km\/h recorre unos 17 metros por segundo. Contando solo 0,2 segundos de reacci\u00f3n, ya avanza unos 3,3 metros, y en la conducci\u00f3n real hay que sumar el tiempo que tardas en decidir, as\u00ed que la distancia es a\u00fan mayor. Por eso es tan importante mantener la distancia de seguridad.<\/p>\n<p>Tambi\u00e9n tiene que ver con el tiempo de reacci\u00f3n que en las salidas del atletismo se use un disparo (sonido). Se considera que reaccionamos al sonido un poquito m\u00e1s r\u00e1pido que a la luz (la vista). Adem\u00e1s, en las carreras de velocidad, si alguien se mueve antes de que pasen 0,1 segundos desde la se\u00f1al de salida, se considera salida nula. La norma se basa en la idea de que, por muy r\u00e1pido que sea una persona, necesita al menos ese tiempo para moverse despu\u00e9s de o\u00edr la se\u00f1al.<\/p>\n<p>A primera vista parece un simple juego, pero en realidad es un experimento cient\u00edfico muy profundo, donde se combinan a la perfecci\u00f3n el funcionamiento del cuerpo humano (biolog\u00eda) y las leyes del movimiento de los objetos (f\u00edsica). Cuando te pones a investigar los &#8220;\u00bfpor qu\u00e9?&#8221; escondidos en lo cotidiano, el mundo se vuelve mucho m\u00e1s divertido.
