Meter
The meter is the base unit of length in the International System of Units (SI). It is the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
History/Origin
The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the international prototype meter was established as the length of a prototype meter bar, made of an alloy of platinum and iridium. In 1960, the meter was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86.
Current Use
The meter is used worldwide in many applications such as science, engineering, and trade. The United States is one of the few countries in which the meter is not widely used in everyday life and trade.
Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
