X-Ray Abscissa #Haiku #Poetry

A haiku written by Lee Sonogan

105. Find the abscissa of the point P. A ray of light is travelling along  the line x= 1 and gets reflected from the line x+y=1, find the equation of  the line

Some time ago, I investigated the possibility that a computer might be able to reconstruct a picture from sets of very accurate X-ray measurements taken through the body at a multitude of different angles. – Godfrey Hounsfield

Primary axis,

Left to right horizontal,

Ordered pair taxus.

Mathematics accomplishes really nothing outside of the realm of magnitude; marvellous, however, is the skill with which it masters magnitude wherever it finds it. We recall at once the network of lines which it has spun about heavens and earth; the system of lines to which azimuth and altitude, declination and right ascension, longitude and latitude are referred; those abscissas and ordinates, tangents and normals, circles of curvature and evolutes; those trigonometric and logarithmic functions which have been prepared in advance and await application. A look at this apparatus is sufficient to show that mathematicians are not magicians, but that everything is accomplished by natural means; one is rather impressed by the multitude of skilful machines, numerous witnesses of a manifold and intensely active industry, admirably fitted for the acquisition of true and lasting treasures. – Johann Friedrich Herbart
