Long Cubit

The long cubit is an ancient unit of length that is a variation of the standard cubit, measuring from the elbow to the tip of the middle finger. The long cubit is longer than the common cubit, typically about 21 inches (approximately 53 centimeters).

It was used in ancient civilizations such as Egypt and Mesopotamia for construction, land measurement, and crafts, especially when more precision or a larger unit was needed.

Key points:

Long cubit ≈ 21 inches (53 cm)
Longer than the standard cubit (usually about 18 inches)
Used in ancient architecture and surveying
Provided a larger base unit for measurements in construction

The long cubit helped ancient builders and surveyors manage larger scales while still relying on the human body as a reference.

Bohr Radius

The Bohr radius is a fundamental physical constant that represents the average distance between the nucleus and the electron in a hydrogen atom in its ground state, according to the Bohr model of the atom.

Its value is approximately 5.29177 × 10⁻¹¹ meters (about 0.529 angstroms).
Named after physicist Niels Bohr, who introduced the model in 1913.
It sets a natural length scale in atomic physics and quantum mechanics.
Used to describe atomic sizes and electron orbitals.

Key facts:

Bohr radius ≈ 5.29 × 10⁻¹¹ m
Represents the typical size of a hydrogen atom’s electron orbit
Fundamental to quantum physics and atomic structure

The Bohr radius is essential for understanding atomic dimensions and quantum behavior of electrons.
