Golden ratio offers unity of science

- By Wits University

It is said to represent a “cosmic constant” found in the curvature of elephant tusks, the shape of a kudu’s horn, the destructive beauty of Hurricane Katrina, and in the astronomical grandeur of how planets, moons, asteroids and rings are distributed in the solar system, to name but a few.

Now, researchers from the Universities of the Witwatersrand and Pretoria are also suggesting that the “Golden Ratio” – designated by the Greek symbol ∅ (letter Phi) with a mathematical value of about 1.618 – also relates to the topology of space-time, and to a biological species constant (T).

Jan Boeyens, a former Wits University Professor and now at the Centre for Advancement of Scholarship at the University of Pretoria, and Professor Francis Thackeray, a palaeontologist at Wits University’s Evolutionary Studies Institute, present their latest research in scientific correspondence, titled: Number theory and the unity of science, published online in the South African Journal of Science (SAJS) on Wednesday, 26 November 2014.

Boeyens and Thackeray have a shared interest in how the Golden Ratio is expressed, from the spiral structure of the cochlea ear-bone in a 2-million-year-old fossil hominin from the Cradle of Humankind World Heritage Site in South Africa; to the logarithmic spirals of inter-stellar galaxies, the structure of DNA, the growth of many plants, and even in the Periodic Table of the elements.

Thackeray investigates whether 1.61 is present in biology as an approximation of the absolute mean value of a hypothesised species constant (T) – associated not only with living species of mammals, birds, reptiles, insects and beetles, but also with extinct species (Australopithecus, Paranthropus and early Homo).

His argument is based on statistical analysis of measurements obtained from animals of the same species, whether vertebrates or invertebrates. “Zoologists and palaeontologists recognise the number 1.618 in the logarithmic spiral in the growth of mammalian ear structures (the cochlea), whether in modern humans or in australopithecines about 2 million years old. They recognise the same number in the growth structures of the spiral shells of certain molluscs. In addition, they identify the same value for spiral growth structures of fossil ammonites more than 65 million years old,” Thackeray explains.

Boeyens researches questions that relate to the mathematical number (1.618) in the context of chemistry, physics, space-time, relativity and quantum mechanics. Meteorologists recognise the number 1.618 in the spiral structure of hurricanes, while astronomers claim that the structure of certain spiral galaxies can also be identified with Phi.

Boeyens discusses the remarkable cosmic occurrence of this number with reference to space-time, relativity and quantum mechanics. He claims that concepts associated with relativity and quantum mechanics can be integrated, through the number 1.618.  

The researchers say that the “time has come to recognize that relativity and quantum theories can be integrated, and linked numerically to the value of a mathematical constant – whether in the context of space-time or biology”.

About the researchers:

Professor Jan Boeyens started his academic life as a crystallographer. In order to try to understand molecular structures revealed by X-ray diffraction, he turned to theoretical chemistry and worked at the University of the Witwatersrand for 20 years. On retirement, at the University of Pretoria (UP), he had the opportunity to explore theories of matter, waves and numbers, having produced six books on topics ranging from number theory to cosmology. The central theme has crystallized around the Golden Ratio, chemical periodicity and cosmic self-similarity. He is currently based at the Centre for the Advancement of Scholarship at UP.

Professor Francis Thackeray is a palaeontologist who served as director of the Institute for Human Evolution at Wits University for five years since 2009, prior to the establishment of the new Evolutionary Studies Institute where he is now based. He is a scientist with a broad spectrum of research interests, including human evolution, stable carbon isotope analyses of hominin fossils, and the quantification of past climatic change. He obtained degrees in zoology, archaeology and environmental studies at the University of Cape Town, and his PhD in anthropology at Yale University, based on a study of fossils from Wonderwerk Cave. He was appointed head of the Department of Palaeontology at the Transvaal Museum in 1990, and subsequently served as its director, and has served as president of the South African Archaeological Society and president of the Palaeontological Society of Southern Africa.
