Miniaturization Miniaturization Miniaturization (Br.Eng.: "Miniaturisation") is the trend to manufacture ever smaller mechanical, optical and electronic products and devices. Examples include miniaturization of mobile phones, computers and vehicle engine downsizing. In electronics, Moore's law, which was named after Intel co-founder Gordon Moore, predicted that the number of transistors on an integrated circuit for minimum component cost doubles every 18 months. This enables processors to be built in smaller sizes. The history of miniaturization is associated with the history of information technology based on the succession of switching devices, each smaller, faster, cheaper than its predecessor.

Rule of 72 Rule of 72 In finance, the rule of 72, the rule of 70 and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling. Although scientific calculators and spreadsheet programs have functions to find the accurate doubling time, the rules are useful for mental calculations and when only a basic calculator is available. These rules apply to exponential growth and are therefore used for compound interest as opposed to simple interest calculations. They
