On page 162 of his autobiography [2] Dr. John / Mac Rebennack wrote: "Goofer dust is a combination of dirt from a graveyard, gunpowder, and grease from them (St. Roch Cemetery, New Orleans) bells." The result usually varies in color from "a fine yellowish-grey" to deep "black dust" depending on the formula, and it may be mixed with local dirt ...
t. e. The Millennium Prize Problems are seven well-known complex mathematical problems selected by the Clay Mathematics Institute in 2000. The Clay Institute has pledged a US$ 1 million prize for the first correct solution to each problem. The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
Order of operations. In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations. The rank of an operation is called its precedence, and ...

When Peggi Wegener experienced a short popping sensation in her head that quickly passed, she didn’t realize it the first sign she’d had a brain aneurysm. Here's what she did next.
Map of Königsberg in Euler's time showing the actual layout of the seven bridges, highlighting the river Pregel and the bridges. The Seven Bridges of Königsberg is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler in 1736 [1] laid the foundations of graph theory and prefigured the idea of topology.
A boat carrying migrants sank off the coast of Yemen, leaving more than two dozen people dead or missing, the U.N. migration agency said Sunday, the latest in a string of shipwrecks that have left ...
