standard normal
28.6 is the standard notation. The standard form(also called scientific notation) is: 2.86 × 101
One vibration per second is called a hertz (Hz). It is the standard unit of frequency in the International System of Units (SI) and is used to measure cycles per second in various contexts, such as sound waves and electrical signals. For example, a frequency of 60 Hz means that an event occurs 60 times in one second.

The standard deviation of the sample mean is called the standard error. It quantifies the variability of sample means around the population mean and is calculated by dividing the standard deviation of the population by the square root of the sample size. The standard error is crucial in inferential statistics for constructing confidence intervals and conducting hypothesis tests.
what is fax called in english --- facsimile
Facsimile also known as a fax
The first facsimile machine, which transmitted images over telegraph lines, was developed in the early 19th century. Scottish inventor Alexander Bain created a version in 1843, but it was not until 1861 that Giovanni Caselli introduced a more practical facsimile machine called the "pantelegraph." This device could transmit handwritten messages and images over long distances, marking a significant step in the development of facsimile technology.
Of course "fax" is a shortening of "facsimile", so early machines were often called "facsimile machines" and people referred to sending a fax as "sending a facsimile". A couple of other names, are telefax and telecopier. Today, a common kind of machine is a multi-function machine that is a copier/scanner/printer/fax. These are called multi-function machines, multi-function printers, or all-in-one's.
That's called a Modem... now superseded by broadband routers.
An Electronic Device
The cell that is threadlike and sends messages is the neuron. Neurons have long, threadlike extensions called axons that transmit electrical signals, or action potentials, to communicate with other neurons, muscles, or glands. These signals facilitate the processing and transmission of information throughout the nervous system, playing a crucial role in bodily functions and responses. Neurons also have dendrites that receive signals from other cells, contributing to their messaging capabilities.
It is called an amplifier.

A stellar source of periodic radio signals is called quasar. This runs off of radio waves.
Also called as facsimile, fax is a document sent or transfered through a telephone line. Today, fax has upgraded tp internet fax where documents can be sent and received simultaneously.
