Stalagmites all adhere to a mathematical rule, scientists have discovered after creating equations showing how the dramatic mineral formations develop into different shapes. The new mathematical descriptions could help scientists extract more accurate data about past climate conditions, the researchers noted in a study to be published the week of Oct. 13 in the journal PNAS. “It turns out that …

It was April 1989, and the International Gold Council in New York was on the warpath. The culprit: the late AK Dewdney, a mathematician and computer scientist at the University of Western Ontario – and the man who, in one recent column for Scientific American, had thrown into jeopardy the entire basis of global civilization. How? By relating the results …

According to a recent study, events geologists use to distinguish transitions between geological chapters in Earth’s story follow a hidden hierarchical pattern, one that could shed light on both past and future tumult. “Geological time scales may look like tidy timelines in textbooks, but their boundaries tell a much more chaotic story,” says study co-author Andrej Spiridonov, a geologist and …
