Physics and mathematics use Greek letters mainly for convenience, tradition, and clarity. Here’s why:

1. More Symbols Needed

• The Latin alphabet (A–Z) isn’t enough to represent the many variables in math and physics.

• Greek letters add 24 extra unique symbols, expanding the available pool.

2. Established Conventions

Over time, certain Greek letters took on standard meanings:

3. Visual Distinction

Greek letters look different, helping avoid confusion between variables (e.g., using λ for wavelength avoids using a Latin l or w).

4. Historical Influence

Many early scientists and mathematicians were from Greek or Hellenistic backgrounds, so Greek notation became embedded in academic tradition.
