MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (13, 15, 17, 27, 29, 31, 56, 65, 67, 69, 91, 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. The first user who solved this task is Nasrin 24 T.

Saving Life
A college physics professor was explaining a particularly complicated concept to his class when a pre-med student interrupted him.
"Why do we have to learn this stuff?" The young man blurted out.
"To save lives," the professor responded before continuing the lecture.
A few minutes later the student spoke up again. "So how does physics save lives?"
The professor stared at the student for a long time. "Physics saves lives," he said, "because it keeps the idiots out of medical school."
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. The first user who solved this task is Nasrin 24 T.

CeresIn 1801, Italian astronomer, Giuseppe Piazzi of Palermo, discovered the first and largest asteroid, 1 Ceres, between the orbits of Mars and Jupiter. After only 41 possible days of observation, he lost it in the sun after 11 Feb 1801. He proposed the name Ceres Ferdinandea, in honour of Sicily's patron Roman goddess, and his patron, the king. Its diameter is about 960 km (600 miles), and it revolves around the Sun in 4.6 yrs. This sighting followed that of the planet Uranus (1781) by British astronomer William Herschel. Piazzi's discovery provided a body between the orbit of Mars and Jupiter fitting the so-called “Titius-Bode's law.” German astronomer Johann Olbers later found more of these bodies now called “asteroids” or “minor bodies of Solar System.” Over a thousand such objects are now known. |
