Leonardo Fibonacci

Leonardo of Pisa, also known as Leonardo Fibonacci or simply Fibonacci, was an Italian mathematician who lived during the late 12th century to the mid-13th century and was considered by some to be the most talented mathematician of Earth's Middle Ages. He is best known for spreading the Hindu-Arabic numeral system throughout Europe and the Fibonacci sequence, which he did not discover but used as an example in his Book of Calculations.

Following the death of her fellow Columbia officers and the resettlement of the Caeliar city-ship Axion on the planet later called New Erigol, former Earth Starfleet Captain Erika Hernandez agreed to be infused with catoms to prevent her death; the process was a success but left her longing for her former life with the desire to attempt to contact someone on Earth. Her first challenge to the Quorum's edict that she not attempt to make contact was a basic SOS coupled with a Fibonacci sequence.
