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.

Vara Castellana

The vara castellana is a traditional Spanish unit of length that was widely used in Spain and its former colonies. It is roughly equivalent to 0.8359 meters (about 32.9 inches).

The vara castellana was commonly used in land measurement, construction, and textiles. Its length could vary slightly by region and time, but the standardized vara castellana became an important reference for legal and commercial measurements.

Key points:

1 vara castellana ≈ 0.8359 meters (32.9 inches)
Used extensively in Spain and Spanish America
Common in land surveying, building, and textile measurement
Predecessor to modern metric units in Spanish-speaking countries

Though largely replaced by the metric system, the vara castellana remains relevant in historical documents and land records.
