Dynastic cycles have been recognized for thousands of years, and a comprehensive theory explaining them was developed by Ibn Khaldun of North Africa in the fourteenth century. Recently updated by Peter Turchin, it has shown predictive power. In a typical cycle, a successful leader unites followers, conquers the country, and founds a dynasty. Over time,

By introducing the mathematical concepts of eccentricity, epicycles, and equant, Ptolemy was able to accurately describe the orbit of planets and predict the positions of the Sun, the Moon, and the planets hundreds of years into the future. His work, summarized in the book Almagest , represented the highest point of science in the ancient times.

Some organisms possess enzymes that allow the net conversion of acetyl-CoA to succinate. This is accomplished by the glyoxylate cycle. The overall reaction of this cycle is: 2 acetyl-CoA + NAD + 2 H2O -> succinate + 2 CoA-SH + NADH + H+ As becomes clear from case studies presented, except from prokaryotes, this pathway does not operate as a real ...
