In his manuscripts, Leonardo Da Vinci left many clues, rules and knowledge about the consequences of friction and the methods to reduce it. The Italian polymath studied and demonstrated aspects ...related to wear, lubrication and contact mechanics, which are the basis of modern tribology. All this knowledge could almost be considered intuitive in the sense that it led him to obtain solutions, concepts and definitions without being mediated by complex processes of reasoning. Through his sketches and extensive reflections, Da Vinci enhanced his knowledge. Present work analyses shows the evidence of knowledge about the origin, factors and the consequences of the relative movement between the bodies, as reported by Leonardo da Vinci and the importance in present day tribology.
•Leonardo da Vinci left clues, rules and knowledge about the consequences of friction and methods to reduce it.•Leonardo's intuitive ideas have been useful to formulate theories, practices and methods, still valid in modern tribology.•The similarities between devices draw by the polymath and modern practices are described.•Four-ball machine proposed by Leonardo is the origin of the standardized method test for lubricants and lubrication systems.
We study the famous Leonardo Da Vinci’s domes, as well as the variations pursued by Rinus Roelofs, from a mathematical viewpoint. In particular, we consider the problem of closing the dome in order ...to produce a spherical structure. We explain why this problem is related to subtle geometric and topological considerations. This is in contrast with the 1-dimensional analog structure, namely Da Vinci’s bridge, that can be easily closed up to make a circular shape.
Starting from a "Seminar of study in the 500th anniversary of the death of Leonardo da Vinci", this contribution intends to analyze "Leonardo's mind" and highlight the pedagogical implications ...present in the vast research conducted by/on the genius of Vinci. Keywords. Leonardo da Vinci--Mind--Actuality--Pedagogy--Philosophy of education
Illuminating Leonardo offers new contributions from major scholars of Leonardo da Vinci covering all aspects of his genius, including his manuscripts and their aftermath, and the various fields of ...art and science.
The Commemoration of Leonardo da Vinci To commemorate the 500th anniversary of the death of Leonardo da Vinci occurring in 2019, I propose the following manuscript, in the form of a virtual interview ...to prof. Giuseppe Maria Pugno (GMP), who commemorated the 500th anniversary of his birth in 1952. The interview, although of a virtual nature, due to the two generations that separate the interviewer (the undersigned, NMP) and the interviewee, is nevertheless based on real answers given by GMP in his writings on Leonardo and the mechanics of solids and structures. The interview is thus confined to this discipline without wishing to touch upon Leonardo’s contributions in other disciplines, or in mechanics itself, e.g. in fluid mechanics or applied mechanics, let alone in the field of art painting and sculpture. Other interesting ideas can be found in GMP’s writings on Leonardo and machines, on Leonardo and hydraulics and on the development of scientific thought in the two hundred years from Dante Alighieri to Leonardo, as well as in essays by other authors on Leonardo, e.g. see notes and references therein. In the last question and answer, interviewer and interviewee will exchange roles to take a look at Leonardo's legacy for a 21st century researcher, with only a few examples.

This review focuses on Leonardo da Vinci's work and thought related to fluid mechanics as it is presented in a lifetime of notebooks, letters, and artwork. It shows how Leonardo's remaining works ...offer a complicated picture of unfinished, scattered, and frequently revisited hypotheses and conclusions. It argues that experimentation formed an important mechanism for Leonardo's thought about natural fluid flows, which was an innovation to the scientific thinking of his day, but which did not always lead him to the conclusions of modern fluid mechanics. It highlights the multiple and ambiguous meanings of turbulence in his works. It examines his thinking suggestive of modern concepts such as the no-slip condition, hydraulic jump, cardiovascular vortices, conservation of volume, and the distinctive path of ascending bubbles we now term Leonardo's paradox, among others. It demonstrates how Leonardo thought through analogies, building-block flow patterns, and synthesis, leading both to successes-especially in the management of water-and to failures, perhaps most obviously in his pursuit of human flight.
