Phi ( Φ = 1.618033988749895… ), most often pronounced fi like “fly,” is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties. Does phi mean wisdom?Īcross the center of the slab is a black enamel band upon which three Greek letters appear, which are the initials of three mystic Greek words phronimon (Phi), thumos (Theta), and katharotes (Kappa) and meaning wisdom, aspiration, and purity. Given two sets S and T, S ∩ T is used to denote the set x. Given two sets S and T, S ∪ T is used to denote the set x. What does the U upside down mean in math? ![]() Frenchman Nicolas Bourbaki invented Ø, a symbol seen by anyone experiencing “New Math.” He also devised a familiar road sign. Most people know phi as “fi,” to rhyme with fly, as its pronounced in “Phi Beta Kappa.” In Dan Brown’s best selling book “The Da Vinci Code,” however, phi is said to be pronounced fe, like fee.īut some of the most fundamental science of the 20th Century is attributed to a mathematician whose name is rather less familiar. The generally accepted pronunciation of phi is fi, like fly. The main difference between benzene and phenyl is that benzene is composed of six hydrogen atoms whereas phenyl is composed of five hydrogen atoms. (Phenyl is pronounced with the accent on phen-, whereas phenol is pronounced with the accent on -ol.) Is phenyl same as benzene? Not to be confused with phenol, fennel, or funnel, or pH. Phenyl (phenyl group Ph): A portion of molecular structure equivalent to benzene minus one hydrogen atom: -C6H5. Eventually, the name for this aromatic compound was changed to benzene. Consequently, when this aromatic ring was attached to something, it was called the “phenyl” group. Historically, the benzene ring was given a name of “phene” as the chemical name. ![]() The Greek alpha comes from the Hebrew and Phoenician aleph, a form of the word for “ox,” eleph, possibly because the character resembled an ox’s head. ![]() One example where the golden ratio often arises is in self-replication, having its mathematical origins in Fibonacci’s sequence for “rabbit reproduction”. The golden ratio, ϕ = 1.61803…, has often been found in connection with biological phenomena, ranging from spirals in sunflowers to gene frequency. Phenyl groups have six carbon atoms in a hexagonal planar structure, of which five are bonded to hydrogen atoms. Phenyl groups are closely related to benzene and can be described as a benzene ring, minus a hydrogen, which can be substituted as a functional group by any other element or compound. A compound containing only one functional group may have more than one α carbon. What is the alpha symbol in chemistry?Īn alpha (symbol: α) carbon is a carbon atom bonded to a functional group in an organic compound the carbon atom next to the α carbon is the beta (symbol: β) carbon, and so on (α, β, γ, δ…). Phi (/faɪ/ uppercase Φ, lowercase φ or ϕ Ancient Greek: ϕεῖ pheî Modern Greek: φι fi ) is the 21st letter of the Greek alphabet. 24 Is pi and phi the same? What is the Phi symbol? ![]()
