Dr. Carl Pulfrich was an early pioneer in the design of sterescopes, images that appear to be three-dimensional that are composed of two separate two-dimensional images. (like a View-Master toy). He’s well-known for observing and documenting what is now known as the “Pulfrich effect”.
The Pulfrich effect is the illusion of depth created by our brains when viewing an object with a dark filter applied to one eye. This effect is the basis behind the 3-D movies that we can see today in theaters.
In Pulfrich’s own words: “I have never been able to observe these effects myself, for I have been blind in the left eye for 16 years.”
Popcorn in a bowl, especially with some sugar on top, was an old staple for breakfast in North America, and was still commonplace by the mid-19th century. The original idea came from the Native Americans.
In America’s early years the Kellogg brothers hadn’t yet invented the corn flake, so popcorn was the best alternative at the time. In fact, John Harvey Kellogg’s wife Ella was a fan of the early breakfast dish. She was quoted extolling the virtues of popcorn as a “wholesome” and “easily digestible”.
If you want to try it out, here’s a recipe.
At least, that was the case in 1995. The number could be even less now. This dying language is the former native tongue of the village of Boung, located on the Adamawa Plateau in the African nation of Cameroon. Most residents of Boung no longer speak it. Of the three speakers that could be found in 1995, one of them was not even a native speaker.
Bushtail possums take up to a year of growing before they are old enough to begin breeding, but they certainly make up for lost time. These possums have an incredibly short gestation period, which allows for there to be multiple mating seasons within just one year. There’s typically a smaller birth season in the spring followed by another more productive season in the fall.
Baby possums spend a lot more time nursing than they do in the womb. After spending just over two weeks developing in the womb, a baby possum (a joey) stays in the mother’s pouch for 120 days at a time. 80 of those days are spent permanently attached the the mother’s teat.
In 1926 a Budapest coffee house waiter committed suicide, leaving a blank crossword puzzle as an explanation. According to a european publication, The Rotarian, a note with it said: "The solution will give you the exact reasons for my suicide and also the names of the people interested."
The police asked the public if they could help solve the crossword, however no one can find a record of anyone deciphering it.
There are more death-related crosswords on societytwins.com. The puzzle was sent to this girl, Sophie Morgenstein, by her brother, right before he supposedly killed himself.She thinks it's a clue to his death and is asking for help.
