The calendars of the 'Lord of the Rings'

JRR Tolkien believed fantasy literature was an entirely different world

'All that is gold does not glitter, not all those who wander are lost; the old that is strong does not wither, deep roots are not reached by the frost.'

- "The Lord of the Rings" author JRR Tolkien (1892-1973)

Tove Jansson's illustrations for 'The Hobbit' rankled some of its diehard fans

The Nordic illustrator was asked to contribute illustrations for the 1960 Swedish translation of J.R.R. Tolkien's "The Hobbit." Some fans were critical, though, arguing that the images didn't accurately represent Tolkien's Middle-earth. One of their most convincing pieces of evidence was Jansson's portrayal of Gollum, which she turned into a massive beast. After seeing it, Tolkien realized he needed to specify that the character was "a small, slimy creature."

Ancient civilizations predicted eclipses by tracking different cycles of their recurrence

The periodic nature of the orbits of the sun, moon, and Earth results in several series called saros cycles, in which the geometric configuration of these celestial bodies that produces an eclipse recurs after about 6585 days. Because eclipses are viewable from different locations on Earth, there exist many saros cycles, one for each ecliptic configuration.

Chronobiologists study the effect of time on biological cycles

Circadian rhythms were first observed in the 1700s, when French astronomer Jean-Jacques D'Ortous de Mairan put a plant in a dark room and watched it still respond to day and night cycles, setting off further studies about specific light-dark biological cycles, an area of inquiry that continues today with the human "clock proteins" at the molecular level.

A map of every object in our solar system

The infographic from 2020 illustrates the complexity of our solar system, mapping over 18,000 objects including asteroids, comets, planets, and moons. Created by biologist Eleanor Lutz using data from NASA, it shows the non-linear distribution of objects due to the sun's gravitational pull. Objects nearer to the sun are more numerous, forming tighter orbits, while those farther out are fewer and more widely spaced.
