Legislative initiatives, especially in the United States, have often become the subject of irrepressible controversy and sincere misunderstanding. So today I want to tell you about bill 246 - a legal act that was considered in the Senate of Indiana in 1897.

Three years earlier, rural physician Edward Goodwin (1825-1902), who considered himself a good mathematician, published an article in the American Mathematical Months in which he claimed to have solved the problem of squaring the circle.

Once I have watched a movie about the computer hackers who have received an access to control the power system, water system and the road navigation of some city (or country). As far as I remember, the attackers nearly destroyed the control system of the entire country, because they had all the controls. The movie was shown at the beginning of 2000, so all that was interpreted as a science fiction. But the ideas that were shown in the movie gradually begin to be embodied by the real criminals. Thus, recently it became known that the unknown people managed to take control of U.S. public water system by remotely accessing one of the water treatment facilities and controlled the equipment.
