However, these formulas were not created in that order, with Erlang B being the first to be invented by a Danish mathematician named AK Erlang. In 1917, AK Erlang followed this up by creating the Erlang C formula, before another mathematician, named Conny Palm, then invented the Erlang A formula in 1946.

Is Erlang the only language that uses beam?

Erlang isn’t the only language that operates on BEAM; there are multiple others. The main one is Elixir. What is Elixir? Elixir was created by José Valim in the early 2010s. He took Erlang and made a thin layer on top of it that had a more modern syntax that resembled Ruby. The resulting language was an improvement over both Erlang and Ruby.

What is the Erlang a formula?

While being an extension of Erlang B and C, the Erlang A formula takes into account the “birth and death” process, theorised by Russian mathematician Andrey Markov.
