Einstein fell in love with sailing as a student in Zurich, a passion that lasted the rest of his life. The only problem was that he was a terrible sailor. He frequently flipped his boat over and had to be rescued dozens of times. (Tinef, Yiddish for "worthless," was the name of his ship.) The New York Times headlined a 1935 story on Einstein's sailing escapades, "Relative Tide and Sand Bars Trap Einstein."

That quantity may appear to be very astonishing at first, but keep in mind that the moon does not create its own light; rather, it reflects the light of the sun. And not particularly well. "The brightness of the Moon depends on the exact angle between the Earth, Moon, and Sun... the brightness of a Full Moon is typically reported as a magnitude around -13, roughly 14 magnitudes or 400,000 times fainter than the Sun," according to Sky & Telescope. That implies the moon has a lot of work ahead of it if it wants to be as visible as our brightest star.

The Venus flytrap was put on the endangered species list a few years ago. Their natural environment has changed as a result of increased urbanisation and agricultural development. Furthermore, the presence of poachers has diminished the plant population in the wild. Poachers take Venus flytraps from their natural environment and sell them for a profit. If you come across a Venus flytrap in the wild, do not try to remove it. Also, if you choose to purchase one, be certain that you do so from a reputable nursery or merchant. We must all work together to keep this interesting species of carnivorous plants alive.

Obviously, it failed. McDonald's has been introducing healthy choices onto its menus for the last decade. It now provides a wide variety of salads, and in 2011, it made it possible to substitute apples for fries in Happy Meals. However, before settling on apples, the fast food company experimented with a variety of fruits and vegetables, most notably broccoli. But not just any broccoli will do. Recognizing that youngsters dislike the waxy green vegetable, McDonald's designed it to taste like bubblegum.

The Exorcist, based on William Peter Blatty's novel of the same name, was produced in 1973 and sparked quite an amount of controversy in the years preceding its release. For instance, when a bird flew into a circuit box, the set used as Regan MacNeil's home burnt to the ground. The only room that remained standing was the one where the exorcism took place. Even creepier, not only did actors get various injuries while making the film, but two of them died shortly after production ended—actors who played characters who perished onscreen. To make matters worse, when the film aired in Rome, lightning damaged a 400-year-old crucifix atop a local church, according to CBS News.

Fine arts contests were conducted in the Olympic Games from 1912 until 1948. Medals were awarded in the fields of literature, architecture, sculpture, painting, and music. The art that was made had to be Olympic-themed, of course.

Pune, which is located at the confluence of the Muthi and Mula rivers, derives its name from the Punya word, which literally means "conflux of two rivers." It was referred to as Punaka Desha in certain old sources before becoming Punekavadi, Punevadi, and Kasaba Pune. The nearby Lord Shiva temple Punyeshwar is where the city earned its name, claims historian Mandar Lavate. Up until 1978, Pune's official name was Poona.

It’s true, cats were considered sacred animals in ancient Egypt. And from what I could see from our visits to Egypt they are still cared for and revered. Our guesthouse in Cairo had plenty of cats hanging out on its rooftop terrace that we enjoyed cuddling with. Cats were thought to bring good luck and they were so revered that when a cat died, the pharaohs had them mummified. As a cat lover, I can relate.
