The machines are called steam engines, which, with external combustion engines, work to convert the thermal energy (the force of heat) of the boiling water into mechanical energy.
The heat resulting from the burning of certain amounts of coal boils the water that turns into steam. That steam is captured and directed to feed a series of elements that start the machine.
Thomas Newcomen invented the steam engine in 1705. With the help of colleagues such as physicist Robert Hooke and mechanic John Calley, Newcomen was the first to make a steam engine proper.
Some years later it was used as a basis for several of the most important inventions of the Industrial Revolution, such as the locomotive, steam ships and factories, among other things.
The steam engine and coal revolutionized production in the factories, both objects were one of the drivers of the industrial revolution.

The Mayas were a Mesoamerican civilization that was established in the Yucatán Peninsula, on what is today southern Mexico, parts of El Salvador, Belize and Honduras and Guatemala. This ancient civilization has been recognized for its incredible advancement in architecture and for how organized and advanced they were as a civilization as a whole. This empire initiated rougly around the year 2000 BC. Among other things, Mayans were great believers in their gods and they built enormous, and now famous, pyramid-temples in honor of these gods. One such god was the serpent god Quetzalcoatl and another example was the pyramid for the god of rain, Chak. Also, the Mayans were known for their social and political organization and structure. Until the 900, the Mayans were being governed by several kings and rulers, each of a region of the vast empire. One of the last ones in record was K´ak´ Tiliw Chan Yopaat, before the decline of the Mayan Empire. It is not certain why the Mayans declined. There are many research studies on the subject. Some scientists believe that it might have been a drought that depleted the region of resources and water, some that it was disease and some overpopulation within the empire. Some also mention corruption and disorder. This happened around the 9th century A.D.
