- “Thermodynamics is the kingdom of the delta.”
- — Clifford Truesdell (1980), The Tragicomical History of Thermodynamics: 1822-1854 (pg. 3)
The isopsephy value of delta is "345",
The number "345" is numerically equivalent to the Greeks work "void" (κενός) or "empty".
The significance of "delta", the symbol "Δ" of the Egyptian pyramids, being numerically equivalent to "345", code for the word "void" or emptiness", is that in the original Egyptian creation myths, which went through several "recensions" (see: recension theory), as shown below, as the religious power centers shifted over the centuries, from which the Greeks constructed their alphabet and god pantheon, the god Nun (or Nu), in the Heliopolis creation myth (3,100BC), and the 8-god family "Ogdoad" (which subsumed the god Nun), in the Hermopolis creation myth (2,400BC), were conceptualized as the god or god family of emptiness, void, chaos, or watery abyss, out of which all the other gods were born.
E | #5
In 2500BC, in Egyptian hieroglyph of a man with his arms raised, shown below became the root etymology of the letter "E", symbolic of a person ‘in action’, or doing ‘work’ of some sort, i.e. expending ‘energy’ as we would say:
In 1000BC, during the formation of the Greek alphabet, letter E became, as the letter epsilon (ε or Ε), the second vowel of the seven vowels, which is thematic, as Plutarch (110) tells us, to being named after the sun, in the vowel ordering scheme, to the second planet in Greek cosmology, the moon being the first "wandering star", the sun being the second. E-words, accordingly, such as energy, existence, engine, equation, experiments, explosion, etc., typically have deep etymological significance, tend to be thematic to this meaning, in respect to a person in action, powered by the sun.
N | #14
In 2500BC, the Egyptians defined or modeled the origin of all things, in their various creation myths, the Heliopolis creation myth, Memphis creation myth, and Thebian creation myth being the three dominate versions, defined, based on the annual Nile River flood, to be "water", or a watery, chaos, or void like state. They conceptualized this by the god Nun (or Nu), the god-goddess pair Nun and Naunet, or the Ogdoad god family, depending. The god Nun or Nu was symbolized by the water wave or wave symbol , which became, over time the letter "N", as follows:
In 750BC, Hesiod renamed "Nun" by the "chaos", which became the Greek rescript of the the Egyptian model of beginning.
In 300BC, the Jews rescripted the god Nun into the character of the prophet Noah or Nun in Islam.
In 50AD, the letter "N" was used as the center letter of the Sator Square puzzle.
New | Negative
Words such as new, neo, neonatology, derive from the etymological sense of new things born out of the Nun.
Mathematical words, e.g. nil, naught, or negative, etc., derive from the premise of a positive (e.g. the sun) coming out of a negative (or nothing), i.e. the vacuum or void of the Nun.
Nous | Neuro
In 500BC, Pythagoras, and his school, considered the the "Nous", the Greek rescript of the Egyptian Nu or Nun, as the "monad", the number 1, and the origin of all things:
- “Anatolius (De Decade, c.285) remarks that the Pythagoreans call the monad ‘nous’ and liken it to the one itself (to heni auten), the intelligible god (to noeto theo), the uncreated (to agenneto), beauty itself (autokalo), the good itself (autoagatho), and—among the virtues—the wisdom (phronesei) of the one.”
- — Bruce MacLennan. (2019). “The Psychodynamics of Numbers” 
In 200AD, Galen employed the term “nerve”, from the Greek neura, from which we get terms “neuro-” based terms, such as neurology or neuroscience.
Mind of god
In 1988, Stephen Hawking, in his Brief History of Time. introduced the phrase "mind of god". He latter elaborated on this is follows:
- “Before we understand science, it is natural believe that god created the universe. But now science offers a more convincing explanation. What I meant, in A Brief History of Time (1988), by [the phrase] ‘we would know the mind of god’, is we would know everything that god would know, if there were a god. Which there isn’t. I’m an atheist.”
- — Stephen Hawking (2014), El Mundo interview, Sep 23 
The phrase "mind of god", according, crudely translates, barring digression on particle physics, as to understand the "nature of the vacuum", one will come to understand the "mind of god". This is not the full etymology, however, as the letter delta, i.e. the pyramid that rises out of the Nun, means or translates, via isopsephy, into the words: emptiness, void, or vacuum.
