Unit Explanations
Second of Arc"
Source UnitA second of arc, also known as an arcsecond, is a unit of angular measurement that is equal to 1/3600 of a degree or 1/60 of an arcminute. It is used primarily in fields that require precise angular measurement, such as astronomy, navigation, and mapping. An arcsecond is a small unit, reflecting the requirement for high precision in measurements of celestial objects and angles on the Earth's surface. The notation for a second of arc is usually represented by a double prime symbol ("), following the degree and arcminute symbols.
Current Use
Today, the second of arc is indispensable in astronomy for measuring the positions and movements of celestial objects with high precision. It is also used in geodesy and cartography to define the precise angular relationships between points on the Earth. Additionally, arcseconds are employed in the calibration of telescopes and other optical instruments where small angular measurements are critical.
Fun Fact
An arcsecond is roughly the angle subtended by a U.S. dime at a distance of 2.4 miles.
Attosecondas
Target UnitAn attosecond (symbol: as) is a unit of time equal to 10^-18 seconds, or one quintillionth of a second. This measurement is incredibly brief, allowing scientists to study phenomena that occur on the scale of atomic and subatomic processes. The attosecond is part of the metric system and is used primarily in physics and chemistry to describe the time required for electrons to move between energy states or to describe the duration of light pulses in high-speed laser applications.
Current Use
Today, attoseconds are primarily utilized in the fields of physics, chemistry, and materials science. Attosecond science has enabled researchers to capture and study fast processes in atoms and molecules, leading to a deeper understanding of fundamental interactions. Industries such as semiconductor manufacturing and quantum computing also benefit from techniques that rely on attosecond measurements to improve device performance and understand material properties at the atomic level.
Fun Fact
The duration of an attosecond is so short that light travels only 0.3 nanometers in that time, which is roughly the size of a hydrogen atom.

Definition
A second of arc, also known as an arcsecond, is a unit of angular measurement that is equal to 1/3600 of a degree or 1/60 of an arcminute. It is used primarily in fields that require precise angular measurement, such as astronomy, navigation, and mapping. An arcsecond is a small unit, reflecting the requirement for high precision in measurements of celestial objects and angles on the Earth's surface. The notation for a second of arc is usually represented by a double prime symbol ("), following the degree and arcminute symbols.
History & Origin
The concept of dividing a circle into degrees and further into minutes and seconds dates back to ancient Babylonian astronomers, who used a sexagesimal (base-60) number system. The division of a degree into 60 parts, known as minutes, and each minute into 60 parts, known as seconds, allowed for more precise measurement and calculation of angles in the study of celestial bodies. This system became widespread with the work of Greek and later Islamic scholars, who advanced astronomical knowledge and navigation.
Etymology: The term 'second' in this context comes from the Latin 'secunda', meaning 'second division' or 'second order', referring to its place in the hierarchical division of degrees.
Current Use
Today, the second of arc is indispensable in astronomy for measuring the positions and movements of celestial objects with high precision. It is also used in geodesy and cartography to define the precise angular relationships between points on the Earth.

Definition
An attosecond (symbol: as) is a unit of time equal to 10^-18 seconds, or one quintillionth of a second.

The attosecond is part of the metric system and is used primarily in physics and chemistry to describe the time required for electrons to move between energy states or to describe the duration of light pulses in high-speed laser applications.
History & Origin
The concept of the attosecond was first proposed in the early 1970s. It was made possible by advancements in laser technology, which allowed scientists to create extremely short pulses of light. The first attosecond pulse was generated in 2001 by a team of researchers, marking a significant milestone in the field of ultrafast optics. This breakthrough has since enabled researchers to observe and manipulate electron dynamics and chemical reactions on unprecedented timescales.
Etymology: The term 'attosecond' is derived from the SI prefix 'atto-', which denotes a factor of 10^-18, combined with 'second', the standard unit of time in the International System of Units (SI).

Today, attoseconds are primarily utilized in the fields of physics, chemistry, and materials science. Attosecond science has enabled researchers to capture and study fast processes in atoms and molecules, leading to a deeper understanding of fundamental interactions.
