Recent technological advances have allowed scientists to make observations on single-molecule dynamics, which was unthinkable just a few decades ago (Nie and Zare, 1997; Xie and Trautman, 1998; Weiss, 2000; Tamarat et al., 2000; Moerner, 2002)—the famous physicist Richard Feynman once described that … Web9 de fev. de 2024 · Part philosophical, part scientific, Leibniz believed that our world - "the best of all possible worlds" - must be governed by what is known as the Principle of Optimality. This seemingly outlandish idea proved surprisingly powerful and led to one of the most profound tools in theoretical physics. Jeffrey K. McDonough tells the story.

WebIn works devoted to the universe, the optimality of its evolution is noted. However, specific mathematical models, according to which the evolution of the universe takes place, are not given in them (see, e.g. [1] ). In the book [2] , instead of the optimality of the evolution of the Universe, the term “cosmic wisdom” is applied.
