Beyond the answers - interesting background to this quiz

Rabelais and the birth of the modern novel

François Rabelais was not only a writer but also a physician and a monk. His pentalogy about the giants Gargantua and Pantagruel, published between 1532 and 1564, combined coarse humour with sharp humanist critique. The word "gargantuan" entered English thanks to his work, and his playful treatment of language influenced later writers from Laurence Sterne to James Joyce.

The Sistine Chapel before Michelangelo

The Sistine Chapel in Vatican City is named after Pope Sixtus IV, who commissioned its construction in the 1470s. Long before Michelangelo painted the ceiling, the chapel's walls were decorated by leading Renaissance artists including Botticelli, Perugino, and Ghirlandaio. Michelangelo's ceiling, completed between 1508 and 1512, later overshadowed these earlier frescoes.

The invention that made the keyboard standard

Christopher Latham Sholes, a newspaper editor from Wisconsin, developed the first practical typewriter in 1868 with the help of Carlos Glidden and Samuel Soulé. The original machine typed only capital letters and was slower than handwriting. Sholes also devised the QWERTY keyboard layout, initially to reduce jamming of adjacent type bars, a design that persists on digital devices today.

How the ear keeps us upright

The sense of balance, or equilibrium, is managed primarily by the vestibular system in the inner ear. Three semicircular canals filled with fluid detect rotational movements, while otolith organs sense gravity and linear acceleration. The brain integrates these signals with visual input and information from muscles and joints, allowing us to stand, walk, and turn without falling.

The accidental discovery of X-rays

Wilhelm Röntgen discovered X-rays in November 1895 while experimenting with cathode rays in his laboratory in Würzburg, Germany. He noticed that a fluorescent screen glowed even when his discharge tube was covered with black cardboard. The first X-ray image he produced was of his wife Anna Bertha's hand, clearly showing her bones and wedding ring. Röntgen received the first Nobel Prize in Physics in 1901.
