Find the right combination
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.
Calculate the number 7266
NUMBERMANIA: Calculate the number 7266 using numbers [7, 7, 3, 7, 29, 707] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (14, 15, 22, 23, 25, 27, 28, 33, 38, 73, 88, 97) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B-C.
English lessons
A missionary suddenly realizes that the one thing he hasn't yet taught the natives he serves is how to speak English, so he takes the chief for a walk in the jungle.
He points to a tree and says to the chief: "This is a tree." The chief looks at the tree and grunts: "Tree."
The missionary is pleased with the response. They walk a little farther and the missionary points to a rock and says: "This is a rock."
Hearing this, the chief looks and grunts: "Rock."
The missionary is really getting enthusiastic about the results when he hears a rustling in the bushes.
As he peeks over the top, he sees a couple of the natives in the midst of heavy sexual activity. Flustered, the missionary quickly says to the chief: "Riding a bike."
The chief looks at the preoccupied couple briefly, pulls out his blowgun and kills them.
The missionary goes ballistic and yells at the chief that he has spent years teaching the tribe how to be civilized and kind to each other.
"How could you kill these people in cold blood that way?" he demands.
"My bike," the chief replies.

Gabriel Gustav ValentinBorn 8 Jul 1810; died 24 May 1883 at age 72.German-Swiss physiologist who was the first person to note the digestive activity of pancreatic juice (1844)*. With Purkinje, one of his medical school teachers, he discovered in 1834 that certain cells on the inner surface of the oviduct contained cilia, tiny threadlike structures that beat in coordinated fashion independently of the nervous system and thus force the ovum to move along the tube. They investigated the occurence of ciliated cells elesewhere among vertebrates)*. In 1836, he identified the neuron nucleus and nucleolus. In 1841 he was the first to observe one type of Trypanozoma (they are now know to cause sleeping sickness). The Valentin knife was named after him.* [Image: Drawing of a neuron by Valentin, showing the protoplasm (a), the nucleus (c), the nucleolus (d) and the axonal cone (b)] |
