Graph Minor Theory László

A monumental project in graph theory was recently completed. The project, started by Robertson and Seymour, and later joined by Thomas, led to entirely new concepts and a new way of looking at graph theory. The motivating problem was Kuratowski’s characterization of planar graphs, and a far-reaching generalization of this, conjectured by Wagner: If a class of graphs is minor-closed (i.e., it is...

Maggots in Nose or So-Called Vermes Nasi

Dr. T. IS. 13. Brown, the Principal of the Lahore Medical College, gives a short but very interesting description of maggots, in his Annual Report of the Mayo Hospital for 1872, page 5, para. 33. As to their origin he says "there can be no doubt that these animals are produced from egg3 deposited by flies in the injured parts, and that they are also sometimes developed in the nose without any s...

Albert - László Barabási from Network Structure

W e are surrounded by complex systems, from cells made of thousands of molecules to society, a collection of billions of interacting individuals. These systems display signatures of order and self-organization. Understanding and quantifying this complexity is a grand challenge for science. Kinetic theory, developed at the end of the 19th century, shows that the measurable properties of gases, f...
