Normally I would not discuss my publications unrelated to my main field of research (mechanical engineering and surface science) in this blog. However, this one, although in a History peer-reviewed journal, deals with the history of mechanics and astronomy. More… Read More
This famous Ancient Egyptian painting on Pharaoh (more accurately, Nomarch) Djehutihotep’s tomb (c. 1880 BCE) entered many tribology textbooks as possible evidence of the use of lubrication in Ancient Egypt. Engineers are quite enthusiastic, although Egyptologists are much more skeptical…. Read More
From our same paper, a historical review: “The theory of wetting represented by Equation (1) was formulated for the first time by Thomas Young in 1805 in his essay “On the Cohesion of Fluids” [8]. The essay does not contain… Read More
This could be a good project for students of dynamics. The tower clock emerges in medieval European cities at about the year 1300 CE: Westminster (1288), Canterbury Cathedral (1292), Salisbury cathedral clock (1306), St. Albans (1326), etc. The pendulum was… Read More
Про трение как “сопутствующее явление” (“Friction as an epiphenomenon”) is a bit “philosophical” paper in Russian about friction. For most conventional textbooks on mechanics, Coulomb’s dry friction is an external phenomenon, which is introduced in an ad hoc manner in addition… Read More
