New technologies were developed, including sewage systems, electricity, light bulbs, electric motors, railroads, automobiles, and airplanes. These technological advances led to significant developments in medicine, chemistry, physics, and engineering. They were accompanied by consequential social change, with the introduction of skyscrapers accompanied by rapid urbanization. Communication improved with the invention of the telegraph, the telephone, the radio, and television. Though mechanical technology is simple, it has allowed for extremely important advancements in the human experience.

Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. Technology, the application of scientific knowledge to the practical aims of human life or, as it is sometimes phrased, to the change and manipulation of the human environment.

The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 km, but less than 70 km of this was above ground and supported by arches. A bathtub virtually identical to modern ones was unearthed at the Palace of Knossos. Several Minoan private homes also had toilets, which could be flushed by pouring water down the drain. The ancient Romans had many public flush toilets, which emptied into an extensive sewage system. The primary sewer in Rome was the Cloaca Maxima; construction began on it in the sixth century BCE and it is still in use today.
This includes the use of pulleys, levers, wheels and axles, wedges, inclined planes, and even cogs and gears. Mechanical technology is used for any task that involves doing mechanical work, which is primarily the motion of objects. Any machine, generator, or tool used to do work uses mechanical technology. Because current technologies are generally accepted as good, future technological developments are not considered circumspectly, resulting in what seems to be a blind acceptance of technological development.
