A doubling you can count
In 1965, engineer Gordon Moore noticed that the number of components that could be economically placed on an integrated circuit was rising at an extraordinary rate. Later versions of the observation focused on transistor counts in chips. The pattern became known as Moore’s Law.
The important part is not the label. It is that the claim can be checked. Count the transistors in successive generations of chips and plot them over time. For decades, the series grew through repeated doublings rather than by a fixed number of extra transistors each year.

A chart like this does not predict next year’s exact battery, radio, or computer. It does tell a planner that a specification may become outdated on a different schedule from the building or contract around it.
It also has limits. Not every technology follows this curve, and even a strong curve can slow down. A measured trend is evidence to revisit an assumption, not permission to promise anything.
One reason the trend lasted as long as it did is that each generation of tools helped engineers make the next one.
