Septennial
A septennial is a period of seven years.
History/Origin
The term originates from Latin 'septennium', used historically to denote a seven-year interval, often in contexts such as anniversaries or cycles in various systems.
Current Use
The term 'septennial' is rarely used in modern timekeeping but may appear in historical or literary contexts to describe events or periods lasting seven years.
Attosecond
An attosecond is a unit of time equal to 10^-18 seconds, used to measure extremely short durations, particularly in atomic and subatomic processes.
History/Origin
The attosecond was introduced in the early 21st century as scientists developed ultrafast laser techniques to observe electron dynamics, marking a significant advancement in time measurement at atomic scales.
Current Use
Attoseconds are primarily used in physics and chemistry to study ultrafast phenomena such as electron movements, chemical reactions, and quantum dynamics, often through attosecond laser pulses and spectroscopy.
