Steam power originally developed slowly over a period of several hundred years until it reached to actual practical application at the beginning of the industrial revolution. The steam engine was one of the most important technologies of the industrial revolution. It was a simple device that used boiling water to create mechanical motion to be utilized in useful work.
Early mills used water power to operate and had to be located near running water such as a river which would freeze in winter and the water was not available, also in dry spells. Flooding would also stop operations. But by using a steam engine, a factory could be located anywhere and could operate the whole year round.
From mines to mills, steam engines found many applications in a variety of industries, improving productivity and technology such as Trevithick's high pressure engine that revolutionized transport. Steam engines found their way to boats, railways, farms and road vehicles.

Well, I've never heard of a student getting detention for calling their teacher by a nickname, that would be unnecessary and a little over dramatic, don't you think? I think if the teacher doesn't like being called said nickname then the teacher would tell the student to stop calling them by said nickname. But if the student has done it multiple times after the teacher has asked them to stop, then the student would be punished by being sent to the E.R for an hour each day depending on how long the teacher wants you in there (my school's room for students who have done something bad, like a reset room). But detention? That would just be silly.
