The text deals with a short circuit situation in electric circuits. It is known that the electric current sharply raises when two or more wires with different electric potential are connected. It should be noted that a short circuit may be very damaging for the equipment involved. It is reported that a short circuit may cause a fire. Much attention should be paid to the diameter of connecting wires that can be heavily overloaded. It is stressed that fuses or other means of protection should be used in any circuit where a short circuit situation may occurr. Thus, all possible measures should be taken to avoid a short circuit.

According to various mysterious sources, the first civilization arose 78000 years ago on the giant continent known as Mu or Lemuria. It had been lasted for amazing 52000 years. The civilization had been destroyed by the earthquake, caused by the shifting of the terrestrial pole which occurred approximately 26000 years ago or in 24000 B.C.
While the civilization of Mu had not reached such a high technology, as other later civilization, but the peoples Mu succeeded in erection of mega-stone buildings, which were able to withstand earthquakes. This construction science has been the greatest achievement of Mu.
