The article recaps facts about nature and science that were discovered previously. In June 1,1958, the Clean Air Act of 1956 was implemented. Clean Air Act bans dark smoke from any chimney in England and Wales. The ban is applicable to all buildings, railway engines and ships, however it directly affects industrial and commercial premises. 100 years ago a notable paper was read by professor W. Phillips related to children's capacity for attention. After referring to various experimental inquiries, he came up with an assumption that a child's attention declines more quickly in the afternoon and that math is the subject that demands more attention than any other subjects.
