Why people shape roofs the same way
Journal Article International Communications in Heat and Mass Transfer · May 1, 2025 The roofs of houses look similar in profile, especially in villages and old settlements. Why? The question is about the common angle of inclination. The answer comes from heat transfer by natural convection. Inspired by the evolution of the sapiens toward ... Full text CiteWater cataracts and the “shortest-time descent” curve (Brachistochrone) as one natural phenomenon
Journal Article AIP Advances · February 1, 2025 This article unveils the connection between design in nature and a classic mathematics problem from 1696 to 1697: the brachistochrone. Some flow designs seem to act as obstacles to flow (cataracts, waterfalls, and roll waves), in contradiction with the nat ... Full text CiteEvolution and irreversibility: Two distinct phenomena and their distinct laws of nature.
Journal Article Physics of life reviews · September 2024 To clarify the place of time direction of change in nature (time arrow), the present article shows why Evolution and Irreversibility are two distinct phenomena. Their distinct laws of nature are the Constructal Law and the Second Law, respectively. The dem ... Full text CiteRecent Grants
