A revealing
A revealing, in a striking and mathematically rigorous exhibit, that the famous Fibonacci sequence — the Fibonacci sequence of Leonardo of Pisa, first published in the 13th century and known through the centuries as "the Divine Sequence" after Luca Pacioli's De Divina Proportione (1509) — is embedded perfectly and infinitely within the letters of the Hebrew alphabet.
Leonardo da Vinci, who illustrated Pacioli's book and studied the spiral growth patterns of plants (phyllotaxis), was among those who anchored what Pacioli called "the Divine Proportion" (a name given for its pervasive appearance throughout Creation — not, of course, referring to the proportions of the Creator Himself) in art and science. The Fibonacci sequence is rooted deeply in nature, science, engineering, and art, generating naturally and optimally the golden ratio (φ ≈ 1.618...). It now reveals itself in the alphabet as well.
The sequence mathematically expresses the phrase "אל - פה" (El–Peh, "God–Mouth") — corresponding to the creation of the world through the speech of the Creator, as stated in the Mishnah (Avot 5:1): "With ten utterances the world was created."
