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.

Cubit (Greek)

The Greek cubit is an ancient unit of length based on the forearm’s length—from the elbow to the tip of the middle finger. In ancient Greece, it typically measured about 18 to 20 inches (approximately 45 to 50 centimeters), though the exact length could vary by region and period.

The Greek cubit was widely used in architecture, construction, and land measurement. It played a crucial role in building temples, monuments, and other structures in classical Greece.

Key points:

• 
  

  Greek cubit ≈ 18 to 20 inches (45–50 cm)

  
  
• 
  

  Based on the length of the forearm

  
  
• 
  

  Used in ancient Greek construction and land surveying

  
  
• 
  

  Important for classical architecture and engineering

  
  

This unit reflects how ancient civilizations used the human body as a natural measuring tool before standardized systems.
