MAPS AND THE VISUAL LANGUAGE OF ASTRONOMY RAS Speciallist discussion meeting Cosmology with maps 12/02/2016 Burlington House, London
“Pictures are undervalued in science. They are not trusted. That is partly the 200-year-old legacy of the French mathematicians Lagrange and Laplace, who scrupulously labored to reduce all logical thought to precise formulae and carefully chosen words; sloppy diagrams were suspect. (…) The picture can now aid, not mislead (or replace!) the scientist. It permits instant comparison, instant comprehension.” Benoit Mandelbrot

“ Galileo lacked a sufficiently good telescope, or he could not be sufficiently attentive to those observations of his, or, most likely, he was ignorant of the art of picturing and drawing, which art serves this work greatly and no less than acute vision, patience, and toil. ” Johannes Hevelius FRS
