But Čapek gave his brother Josef credit for coming up with the word robot – his early drafts used the word "labor." Čapek's robots weren't metal mechanical devices, but rather artificial human-like biological organisms.
Black and white photo from a production of RUR. The set is a nicelymfurnished living room with paintings on the walls and a door and a large window at the back. In front of the door stands a three-legged, round table with a potted plant on it. To the left of the table are a man and a woman, both well-dressed. The man is standing, the woman is sitting in a n armchair. To the right of the table are three figures that appear to be robots. Two of them are wearing a sort of futuristic-looking uniform, and the third is wearing a suit and tie.

Karel Čapek's 1920 play "RUR" (Rossum's Universal Robots) introduced the word robot into the realm of science fiction. The word is derived from Czech words meaning "forced labor," or "slave."

Smaller mammals, below around 3 kg (6.5 lbs.) don't follow the same pattern. Their short urethras and the effects of surface tension result in their passing urine as single drops, not a stream.

Law of urination Researchers at Georgia Inst. of Technology measured the duration of urination in mammals ranging in size from house cats to elephants, and found that they all emptied their bladders over a constant duration of 21 ± 13 seconds.

A baked apple pie with one slice missing sits in a glass bowl on a folded piece of burlap on a wooden table. The slice that was removed sits on a white plate just behind and to the side of the pie. Several whole apples sit on the table behind the pie, and several silver forks sit on the table next to the pie.

The stone had a reputation in Medieval times of having the power to prevent inebriation, perhaps because its pale purple color suggested watered-down wine. Folks out drinking would wear rings of amethyst in an attempt to avoid the effects of the alcohol.

The deepest dive on record, recorded by an electronic sensor attached to one individual, was more than 550 m (1,800 ft) and lasted over 30 minutes. 📷 : coolantarctica.com
Six emperor penguins swim just below the ice in the Southern Ocean. The water below the penguins is very dark but there is some light filtering through the ice , illuminating the penguins. Two large round holes in the ice provide additional light as well as allowing the penguins to surface to breathe.

Emperor penguins dive deeper in the ocean than any other bird. Chasing fish and krill in the Southern Ocean around Antarctica, they commonly dive to depths of 100-200 m (330-650 ft) for an average of 3-6 minutes.

The largest known flea in the world, the mountain beaver flea (Hystrichopsylla schefferi), can reach a length of 0.5 inch (12 mm). As the name suggests, it lives on the mountain beaver (Aplodontia rufa) in the American northwest. The photo below shows a mountain beaver flea next to a cat flea.

The first cards sent by Kodak featured a Kodak employee named Shirley Page and they quickly became known as Shirley cards. The name stuck, even in later years when other models were used.
A Shirley card from 1978. A portrait of a young woman wearing a white, off-the-shoulder dress and a white pearl necklace takes up the top left corner of the card. Below and next to the portrait are swatches of colors and grayscale that the print techs would use to calibrate their machines. Text at the bottom of the card tell them that this particular card is to be used for Vericolor II Type S prints.

Before the advent of digital photography and printing, photographers had to take exposed rolls of film to a lab for processing and printing. To maintain print quality, the labs calibrated the printers every day and the references they used were called "Shirley cards."

A bare rock slope below a vertical rock cliff holds numerous nests of the Chatham albatross. Each of the unusual-looking nests resembles a clay pot with a single chick sitting in each one. The chicks are fluffy and grey and seem comically large for the size of the nest. They fit, but just barely. In the upper right of the photo, an adult is gliding with wings spread.

Chatham albatross (Thalassarche eremita) pairs use the same nest year after year, ending in a raised platform. And since they can live 40 years, the nests can become comically tall. The species is critically endangered, with only 11,000 individuals remaining.

Fire beetles lay their eggs in freshly burnt wood – sometimes even while the wood is still smoldering. The beetles are especially resistant to extreme heat because of a unique copper compound incorporated into the structure of their exoskeleton – like a suit of armor.

Jewel beetles in the genus Melanophila, also known as fire beetles, possess sensitive infrared (IR)detectors on their thorax that can detect forest fires from distances of more than 100 km (62 miles). Large, or long-burning, fires will attract huge swarms of fire beetles to mate and lay eggs.
