The Greek letter λ (lambda) was derived from the ancient Phoenician letter 𐤋 (lāmed) which meant “goad” (a cattle prod).
The lower-case letter λ has many uses in maths, engineering and sciences, including:
- in biology: coliphage λ
- in engineering, mathematics and physics: the wavelength
- in mathematical logic: λ-calculus
- in organic chemistry: λ-convention for non-standard valence states
- in immunology: a type of the immunoglobulin light chain
- in linear algebra: an eigenvalue
- in nuclear physics: the exponential decay constant
- in physics: the linear charge density, λq
λ is also one of the international symbols for LGBT rights.

Not to forget lambda function i.e. anonymous function.
ReplyDeleteHmmm... but does it actually use the symbol λ (as opposed to the word “lambda”)? I've added the λ-calculus though. Thanks!
