Fine-scale interference fringes that decorate caustics produced with white light appear black and white with high contrast. This is surprising, as the elementary expectation, supported by theory and computer simulation, is that the fringes should be highly colored. The fringe separation is several arc minutes and therefore close to the resolution limit of the eye. Under magnification (even of a...

A Steiner triple system of order n (STS(n)) is said to be embeddable in an orientable surface if there is an orientable embedding of the complete graph Kn whose faces can be properly 2-coloured (say, black and white) in such a way that all black faces are triangles and these are precisely the blocks of the STS(n). If, in addition, all white faces are triangular, then the collection of all white...

The inferior education provided to black children is argued to have caused lower levels of human capital production in black schools than white schools The gap in black-white wages can be traced to thi...

Salt-sensitive hypertension is more common and has more severe consequences in urban black populations than in white populations. Increased renal sodium reabsorption through epithelial sodium channels may underlie the development of high blood pressure in black people. Increased sodium channel activity has been detected in subjects with Liddle's syndrome by nasal potential difference measuremen...

OBJECTIVE To examine whether investments made in public health research align with the health burdens experienced by white and black Americans. METHODS In this cross-sectional study of all deaths in the United States in 2015, we compared the distribution of potential years of life lost (PYLL) across 39 causes of death by race and identified key differences. We examined the relationship betwee...
