Robot Etymology

The word robot was introduced to the public at large by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots), which premiered in 1921. The play begins in a factory that makes 'artificial people' - they are called robots, but are closer to the modern idea of androids or even clones, creatures who can be mistaken for humans. They can plainly think for themselves, though they seem happy to serve. At issue is whether the "Robots" are being exploited and, if so, what follows?
However, Karel Čapek himself was not the originator of the word; he wrote a short letter in reference to an article in the Oxford English Dictionary etymology in which he named his brother, painter and writer Josef Čapek , as its actual inventor. In an article in the Czech journal Lidové noviny in 1933, he also explained that he had originally wanted to call the creatures laboři (from Latin labor, work). However, he did not like the word, seeing it as too artificial, and sought advice from his brother Josef, who suggested "roboti".
The word robot comes from the word robota meaning literally labor or work and historically applied specifically to serf labor, and figuratively "drudgery" or "hard work" in Czech,Slovak,Ukrainian, Russian and Polish. The origin of the word is the old Church Slavonic rabota "servitude" ("work" in contemporary Bulgarian and Russian), which in turn comes from the Indo-European root *orbh-. "Robota" in the sense of serfdom was outlawed in 1848 in Bohemia, so at the time Čapek wrote R.U.R., usage of the term had broadened to include various types of work, but the archaic sense of serfdom would still have been known. Robot is cognate with the German word Arbeiter (worker).
In Hungary, the robot was a feudal service, which was rendered to local magnates by peasants every year.

PUFFIN BURROWS

Puffins dig their burrows using their bills and feet. They prefer to make their burrows in earth or between rocks on steep sea cliffs so predators cannot easily reach them. They use their bills to cut into soil and then shovel away loose material with their feet. They dig dog-like, shoveling dirt out behind themselves. Most burrows are 2 to 3 feet long (70 to 110 cm), which is as long as the arm length of an adult human. At the back of the burrow the parents build a soft nest of feathers and grass where they incubate the egg. The burrows often have a toilet area at the first bend. The young chick uses this area as a bathroom so it doesn’t soil its feathers. As it matures, the toilet is moved closer to the burrow entrance, helping to keep the chick clean. If the chick became too soiled, it may damage it’s waterproofing, a fatal circumstance once the chick takes to sea.
