Putting a machine on the farm, a tractor, increased food productivity at least tenfold over the technology of the plow and the horse. The third, and final stage of technological evolution is the automation. The automation is a machine that removes the element of human ...
The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve". The model calls the first group of people to use a new product "innovators", followed by "early adopters". Next come the "early majority" and "late majority", and the last group to eventually adopt a product are called "laggards" or ...

A north–south meridian was created using two merkhets aligned with Polaris, the north pole star. The time was determined by observing particular stars as they crossed the meridian. [24]
Technology adoption is the most common phenomenon driving the evolution of industries along the industry life cycle. After expanding new uses of resources they end with exhausting the efficiency of those processes, producing gains that are first easier and larger over time then exhaustingly more difficult, as the technology matures.
