A 1994 University of Chicago study entitled The Social Organization of Sexuality found that on average men have 74% more opposite­gender partners than women, confirming a view that men are more promiscuous. But whoever reported this finding was lying or confused! We’ll show you how to use the properties of vertex degrees in a graph to prove this. Let’s recast opposite­gender partnering in graph...

J. E. Shaw

1866 he used to get up every morning at six in order to get from Bath to his classes in Bristol punctually. In 1869 he went to Edinburgh to complete his course, and qualified there in 1872. He was House Physician at the Edinburgh Royal Infirmary, a Fellow of the Edinburgh Botanical Society and President of the Royal Medical Society of Edinburgh. In 1875 he returned to Clifton and two years late...

Highly Excited Friedmann Universe

A highly excited Friedmann universe filled with a scalar field and radiation has been considered. On the basis of a direct solution to the quantum-mechanical problem with a well-defined time variable, it has been shown that such a universe can have features (energy density, scale factor, Hubble constant, density parameter, matter mass, equivalent number of baryons, age, dimensions of large-scal...

A modified Friedmann equation

We recently formulated a model of the universe based on an underlying W3symmetry. It allows the creation of the universe from nothing and the creation of baby universes and wormholes for spacetimes of dimension 2, 3, 4, 6 and 10. Here we show that the classical large time and large space limit of these universes is one of exponential fast expansion without the need of a cosmological constant. U...
