Emmett's needle

An Emmett's needle is a small object that is used to collect and process information during problem solving. It was invented by American engineer John Dewey Emmett in 1927 and became one of the first examples of the use of computers in scientific research.

An Emmett needle is a small metal rod with a needle at the end. The pen is inserted into the computer and used to enter information in the form of numbers, symbols or text. The needle then moves the data to a computer where it can be processed and analyzed.

Using an Emmett needle allows you to speed up the process of collecting and processing data, which is especially important in scientific research where a large amount of information is required. In addition, Emmett's needle can be used to automate processes such as monitoring production lines or managing inventory management systems.

Even though the Emmett needle was invented over 90 years ago, it continues to be used in scientific and engineering applications to this day. It is an example of how simple but effective devices can greatly simplify and speed up information processing.
