The logo itself bears some complexity within it. The Greek letters are, from left to right, Psi, Sigma and Phi. Chi (X) in the center.
Psi, as the first letter in the logo, stands for Psychology as well as Psyche (psychē in Greek = Soul).
The second letter, Sigma, stands for Sophia, which is also the first letter of the word “Sophia” in Greek. Sophia signifies wisdom as well as, in a mathematical sense, the sum of all the parts in the logo. Sigma is used in maths to symbolize a sum.
Phi stands for Philosophy, which signifies literally the love or affinity to wisdom, and Philosophy as a subject itself, and the third letter of the logo. As it is the third letter of the logo, it also symbolizes the trinity of “Psi”, “Sigma”, and “Phi”.
All three of them are fusioned into the term PsychoSophy – but instead of an “i” a “y” is used for “Psi >> Psy” and “Phi >> Phy“. So to speak, thus there is a “Double-Y” or the doubled power of “Y”. “Y” (Ypsilon, Ipsilon, Übsilon) stands for the stellar constellation of Perseus and the zodiac sign Cancer, as both constellations resemble – at least in part – the shape of a “Y”. The ypsilon, is the first letter that the Greeks added to their alphabet and has the numerical value 400 according to the Milesian system.They took a variant of the Phoenician waw for it, after the other variant was already used for the digamma. The new letter received the Greek name Ypsilon (pronounced üpsilon), which means “bald Ü” (German: “kahles Ü”). The Etruscans passed this letter on to the Romans as “Ü”, who used it as the last letter of their alphabet for the time being in the form of a V for the sounds “u”, “v” and “w”.
The “Y” also stands for the interrogative “why”, as the English pronounciation of “Y” is “why”. Did the Greek put “Y” at the first position in their alphabeth to always first raise the question “why”? 😉 Today it is the 20th letter of the Greek Alphabeth.
Additionally the large ypsilon denotes a meson in physics, usually the “ram horn variant” of a “Y” is used. According to today’s knowledge of particle physics, mesons (from Greek: τὸ μέσον (tó méson) “the middle”) are unstable subatomic particles, which are built up of one quark and one antiquark (the antiparticle of a quark). Mesons are thus subject to the strong reciprocal (inter-) action. Since they are composed, they are no longer called elementary particles as they used to be. Quarks have a spin, so a meson can consist of two quarks with antiparallel or with parallel spin. In addition, all these mesons can also have internal excited states described by their orbital angular momentum, as well as radial excitations. This increases their energy so that they have different properties (especially decay products) than the ground state mesons. Mesons are created in high-energy particle collisions (e.g., in cosmic rays or in high-energy physics experiments) and decay in fractions of a second. If the latin Y is used, i. e. without “ram horns”, it stands for “hypercharge” in physics. In particle physics, hypercharge is a quantum number. It is used to describe particles subject to the strong (reciprocal) interaction.
Furthermore, the ypsilon represents the thought of whether you are taking the right path in life: The Y looks like a path that forks in two directions.
The fourth letter is the X, which is the 22nd letter in Greek alphabeth, the CHI – like the CHI (Qi) in asian realms, which is a term for the vital/life energy, e.g. in Traditional Chinese Medcine. In physics it is also symbolizing the trait of a material to be polarizable and magnetizable. In maths it is the sign for multiplication. Additionally it is the cross of St. Andrew and symbolizes Christ. So all of the contents of the logo are a product, a multiplication, which reinforces itself and all the elements reciprocally in interrelation.
The fifth letter is a stylised M, in form of a purple Sinus Wave, which stands for the magical life, technology and management respectively. M is the 12th letter of the classical alphabet and the 13th letter of the modern Latin alphabet. “Mü” is the 12th letter of the Greek alphabet and has the numerical value 40 according to the Milesian system and the equivaent of M. Its minuscule “μ” symbolizes “micro” and is i. a. used to signify the muon (also an elementary particle).
