Las hormigas andarinas

Colocamos 1000 hormigas andando sobre un trozo de madera de 1 metro de largo ( a efectos del problema , consideramos solo la longitud como medida importante , y consideramos todo sobre el mismo plano)

Cada hormiga anda a una velocidad constante de 1 m/s

Las hormigas son colocadas todas ala vez y en posiciones al azar en la madera , tambien aleatoriamente , algunas empiezan a andar hacia la derecha y otras hacia la izquierda.

Cuando 2 hormigas se encuentran, cambian su sentido del movimiento:

Cuando una hormiga alcanza el final del palo , caen fuera. Finalmente todas ellas caeran.

¿Cual es el mayor tiempo que aguantará la hormiga que caiga la ultima?

Este acertijo solo requiere imaginacion, ningun conocimiento matematico.Un niño de 7 años podria resolverlo…lo que no quiere decir que sea facil..;)

¿Podeis ver algo aquí?


Esta imagen es muy conocida , pero , si no la has visto antes , aparte de manchas negras , ¿que puedes identificar?

Si no la viste antes , prueba tambien esta

Muerto por dos veces


Os propongo el siguiente enigma.

Lo encontré hace tiempo en un blog ( que enlazaré al final cuando se resuelva) ; es muy enrevesado , dificil y original , y allí no pudimos resolverlo ( me incluyo , claro) y el administrador del blog tuvo que dar la solucion.

Como en otras ocasiones , hay que hacer preguntas a las que responderé SI , NO o IRRELEVANTE.

Como estamos en plena canícula , perdonadme si estoy un par de dias ( procuraré que no sean mas de 2) sin contestar.

El enigma dice así:

Tras pasar la tarde haciendo numeros, Pedro acabó muerto en el suelo de la habitación con un balazo en la cabeza y otro en el pecho. La alfombra, con manchas de sangre, que tambien aparecian por toda la habitación, estaba cubierta de cristales de la mesa que, al romperse, había dejado caer una de las dos copias del chequeo médico de Pedro (la otra no estaba) y un justificante bancario de haber extraido tres mil euros de su cuenta. Junto a Pedro, el palo de billar que usaba todas las noches para jugar y una pistola. La policía llegó avisada por vecinos que oyeron el sonido de un disparo y Luisa, la novia de Pedro, fue detenida por el crimen al hallarse sus huellas en el cadáver, una pistola en su bolso y confesar el crimen. Sin embargo, podriamos decir que hubo dos asesinos de Pedro.
¿Qué pasó?

Hay que intentar relacionar con la explicacion los diversos objetos que aparecen en la escena , ya que practicamente cualquier objeto descrito es relevante en la historia.

Ya podeis empezar a preguntar…

PD: La foto es pura nostalgia detectivesca sin relacion con el caso…

Avances relevantes en la investigacion ( obtenidos de los comentarios ):

Pedro intentó suicidarse.
La prueba de la parafina hubiera dado negativa.
Uno de los disparos se hizo con silenciador.
Luisa mató a Pedro.
Pedro sufria una enfermedad terminal.
No tenia dinero encima ( cantidad importante , vamos) cuando murio
La pistola encontrada junto a él habia sido disparada.
El primer balazo fue el del pecho.
Quedó herido y llamo a Luisa para que lo matara y no sufriera mas.
Los 3000€ eran para un soborno.
Habia un seguro de vidas por medio.

De zorros y conejos


Espero que este problema os guste; es algo mas dificil ( al menos su solucion matematica) de lo habitual en este blog , pero implica un analisis de la situacion que a mi resulta muy interesante.

En este analisis hay que enfocar el desarrollo del problema segun el comportamiento del zorro.

El problema dice así:

Un zorro ve a un conejo situado a 90 metros de distancia al sur de donde él se encuentra; el conejo empieza a correr en linea recta , a una velocidad de 4 m/s en direccion Este.Al mismo tiempo que el conejo , el zorro empieza a perseguirlo , corriendo a 5 m/s.

¿Cuantos metros habrá recorrido el zorro cuando alcance al conejo?

Notas :

1. Es un problema matematico , no tenemos en cuenta las aceleraciones iniciales ni posibles alteraciones en las velocidades de ambos animales ( es decir , nada de si el movimiento del conejo es en zig-zag o excusas parecidas)

2.La distancia pedida es la minima requerida , claro , no vale decir que hay infinitas soluciones si el zorro se dedica a correr sin sentido.

3. El zorro es un animal listo , pero no es un matematico ni adivino.

4. No hay trucos respecto a la curvatura de la Tierra ni a la situacion geografica , es decir no estamos en los polos ni cerca de ellos , que ya nos conocemos…;) , consideramos la superficie plana y el Este y Sur son siempre Este y Sur.Es un problema matematico,con razonamiento logico pero no de pensamieto lateral

Todos los enfoques serán bienvenidos.

¿Mentiré hoy?


Juan es un mentiroso con una peculiaridad. El miente 6 dias de la semana , pero hay un dia de la semana ( siempre el mismo , claro) en el que dice la verdad.

En tres dias sucesivos , nos dijo lo siguiente:

Dia 1: “Miento los lunes y martes”
Dia 2: “Hoy es jueves, Sabado o domingo”
Dia 3: “Yo miento miercoles y viernes”

¿Que dia de la semana es el que Juan siempre dice la verdad?
