Einstein was not a participant in the Manhattan Project, although he was essential in its inception. German scientists discovered nuclear fission of uranium in the late 1930s, which was a crucial step toward the construction of the atomic bomb. Much of the world's uranium was stored in the Congo, which was then a Belgian territory, so two Hungarian-American physicists called Leo Szilard and Eugene Wigner persuaded Einstein to send a letter to his friend, the Queen of Belgium. Instead, Einstein advised writing a letter to a Belgian minister, but a chance meeting with an economist who knew President Roosevelt resulted in a change of heart and a letter that pushed America to begin its own tests.

Ethiopians also have a distinct system for counting the hours of the day. They feel it is less confusing if the clock starts when the day does, for reasons that are difficult to refute. As a result, dawn is at 1 o'clock and sunset is at 12 o'clock. The 12-hour night clock then kicks in. So, while purchasing bus tickets or other forms of transportation, make careful to inquire as to whether the departure time is in Ethiopian or Western time.

They’re not necessary for tourists, but foreigners living in Japan can have one handmade in small, local shops.

There are several theories as to how the phrase "it's raining cats and dogs" came to be. One example is that when houses had thatched roofs, pets and other small animals (squirrels, groundhogs, and so on) would nestle into the straw for warmth. When it rained, however, the straw became slick and the animals slid out, giving the impression that it was literally raining cats and dogs.

Plenty of Japanese celebrate Christmas, but the festive fare isn’t what you might expect. In Japan, it’s traditional to head to your local KFC on Christmas Eve. An estimated 3.6 million Japanese feast on the KFC Christmas Dinner and hours of queuing and ordering weeks in advance is expected. Some say turkey and chicken wasn’t widely available for the Christmas-curious Japanese, so Colonel Sanders stepped in to answer the demand…

Japan is made up of nearly 7,000 islands. The little island of Okunoshima in the Inland Sea is best-known for its curious, big-eared population. The island was used to test chemical weapons during World War II, and it’s said the test subjects roamed free after the war. Either way, the numbers flourished in a predator-free environment (dogs and cats are banned from entering), and today Okunoshima is a popular spot for cuddle-bunny tourists.

Paris is the fashion capital, and the majority of well-known fashion brands are French (Chanel, Louis Vuitton, Dior, Jacquemus, you name it). Of course, they were the ones who came up with the military uniforms as well. The French were the first to deploy camouflage clothes in the military; the name "camouflage" loosely translates to "make up for the stage."

This one is a bit debatable, as some fans argue that it isn't canon. This is due to the fact that Sonic's entire name was never revealed. Archie Comics, which publishes two separate Sonic comics, published a comic in which Sonic's middle name is Maurice but his first name is never revealed. Sonic's first name is really Ogilvie, according to one of the Archie Comics authors. Fans disagree, claiming that Archie Comics' Sonic isn't actual canon, and that only the video games and Japanese comics are.

The Stonewall Inn in New York's Greenwich Village was raided by the police in 1969. It was a safe haven for the LGBT community, and rather than submitting, they fought back. Riots erupted as a result of the event, which sparked a global movement that has helped New York remain one of the most welcoming cities for gay people to this day. Indeed, more people identify as LGBTQ+ in New York than in any other American city (yes, we're giving you more NYC facts for free!).

Sure, many civilizations have their own calendars that they prefer to the Western Gregorian calendar, but the majority still obey the unwritten rule of "12 months to a year." Ethiopia is not one of them. Trying to buck the trend, Ethiopians picked up on Spinal Tap's conviction that one more is always better many thousand years ago, and have been counting 13 months to their year ever since. What exactly does this imply? Well, it's still 2009 there in 2017. And so savvy tourist boards can confidently assert that the nation has "13 months of sunlight."

"Go to the 'Around' menu and hold down the center button for about three seconds to play a Breakout (Pong) game while you listen."
