MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (3, 4, 14, 22, 23, 33, 60, 61, 62, 71) 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.

Balcony Life
Bill and Marla decided that the only way to pull off a Sunday afternoon quickie with their 10-year-old son in the apartment was to send him out on the balcony and order him to report on all the neighborhood activities.
The boy began his commentary as his parents put their plan into operation. "There's a car being towed from the parking lot,"
he said. "An ambulance just drove by." A few moments passed.
"Looks like the Anderson's have company," he called out. "Matt`s riding a new bike and the Coopers are having sex."
Mom and dad shot up in bed. "How do you know that?" the startled father asked.
"Their kid is standing out on the balcony too," his son replied.
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.

Donald William KerstBorn 1 Nov 1911; died 19 Aug 1992 at age 80.American physicist who invented the betatron (1940), the first device to accelerate electrons (“beta particles”) to speeds high enough to have sufficient momentum to produce nuclear transformations in atoms. The electrons are accelerated by electromagnetic induction in a doughnut-shaped (toroidal) ring from which the air has been removed. This type of particle accelerator can produce high-energy electrons up to 340 MeV for research purposes, including the production of high-energy X-rays. For such high velocities, the magnetic field is increased to match the relativistic increase in mass of the particles. During WW II, Kerst worked at Los Alamos on tue atomic bomb project. He completed the largest betatron in 1950, at the University of Illinois. |
