MAGIC SQUARE: Calculate A+B*CThe aim is to place the some numbers from the list (3, 5, 7, 10, 12, 13, 18, 36, 69, 71, 77, 78) 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.
Which is a winning combination of digits?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.
An elderly couple who are both widowed have been courting for a long time.
They decide it's finally time to get married. Before the wedding, they go out to dinner and talk about how their marriage might work.

"I would like it infrequently," replies the old lady.
The old gentleman sits quietly for a moment, adjusts his glasses, leans over towards her and whispers: "Is that one word or two?"
Norton David ZinderBorn 7 Nov 1928.American biologist and molecular geneticist who studied a species of Salmonella (bacteria that cause illnesses such as typhoid fever or food poisoning in humans and other warm- blooded animals). He discovered genetic transduction, or transfer of genetic information by viruses. Genetic material is transferred from one bacterial cell to another by means of a phage, or a virus that invades the bacterial cell, assumes control over the cell's genetic material, reproduces, then eventually destroys the cell. His discovery of this genetic transfer has led to further studies into the mapping and behavior of genes found in bacteria. Daniel Nathans in collaboration with Zinder in 1962 demonstrated that RNA from a bacterial virus directed the synthesis by cell extracts of viral coat protein.
