Bertrand Russell once wrote, “Mathematics possesses not only truth but supreme beauty, a beauty cold and austere, like that of sculpture, sublimely pure and capable of a stern perfection, such as only the greatest art can show.”
Can this be the same Russell who, together with Alfred Whitehead, authored the monumental Principia Mathematica, which can by no means be regarded as a work of art, much less as sublimely beautiful? So what are we to believe?

When Wells wrote his story, he regarded the Time Traveller’s theories as little more than metaphysical hanky-panky designed to make his fantasy more plausible. A few decades later physicists were taking such hanky-panky with the utmost seriousness. The notion of an absolute cosmic time, with absolute simultaneity between distant events, was swept out of physics by Einstein’s equations.

WITHIN THE WESTERN North Atlantic Ocean there exists what might be called a triangle of sea extending southwest from the island of Bermuda to Miami and through southern Florida to Key West; then, encompassing the Bahamas, it extends southeast through Puerto Rico to as far as 15° North latitude, and then from there northward back to Bermuda. This is the area commonly called the Bermuda Triangle.

LIGHT I S SOMETHING THAT WE TAKE FOR GRANTED. It is a fact of everyday life, available at the press of a switch. It is the absence of darkness, the gift of the sun. It is a small part of the physics we are taught at school, a thing of ray diagrams and geometry, without substance. But light is not so easily compartmentalized. Its beguiling combination of fragility and endurance, of delicacy and power, captures the imagination just as it has fascinated scientists through the ages.

#119 - A.J. Bishop - Didactics of Mathematics as a Scientific Discipline

Since the work of the International Commission for Mathematics Instruction (ICMI) at the beginning of this century, nobody can challenge the fact that scientific work has been done in the field of teaching and learning mathematics. This research work has been carried out by mathematicians, psychologists, educational scientists, mathematics teacher trainers, and mathematics teachers themselves. However, scientific communication on these issues long remained in its infancy, particularly on an international level; much work was done in isolation; and it was rare to find people who considered that they belonged to a separate scientific discipline, independent from mathematics or educational science.
