I believe that is Euler’s Identity. Euler’s Identity, e[sup]iπ[/sup] + 1 = 0, is a special case of Euler’s Formula, e[sup]iφ[/sup] = cos(φ) + isin(φ) for φ = π.
In 1988, readers of the Mathematical Intelligencer voted Euler’s Identity to be “the Most Beautiful Mathematical Formula Ever”. In total, Leonhard Euler was responsible for three of the top five formulae in that poll.
Ten major American newspapers have or had the word “Intelligencer” as part of their names. The largest today is the Seattle Post-Intelligencer, published since 1863.
The Hartford Courant, published since 1764, has as its motto “Older than the Nation.”
Courant is the present participle of the French verb courir, ‘to run’.
The French President is automatically named Grand Master and awarded the Grand Cross of both the National Order of the Legion of Honour and the National Order of Merit upon taking office.
The constellation Crux, located in the deep southern sky, is the smallest yet one of the most distinctive of the 88 modern constellations. Its name is Latin for ‘cross’.
Crux appears on the flags of Australia, New Zealand, Papua New Guinea, Samoa and Brazil.
The song “Stinkfoot” from Frank Zappa’s album Apostrophe (’) informs us
“Once upon a time, somebody say to me”
This is the dog talkin’ now
“What is your, conceptual, continuity?”
“Well I told 'em right then”, Fido said
"It should be easy to see
“The crux of the biscuit
is the apostrophe”.
Guitar solo follows. An edited version of its lead-off track, “Don’t Eat the Yellow Snow” (source of the saying “Great Googly Moogly!”), was Zappa’s first chart single.
The only recorded fall of snow in the centre of Sydney occurred in June 1836.
“A Fall of Moondust” is a novel by Arthur C Clarke which recounts the sinking of a skimmer boat in a sea of dust on the moon.
In 1961 Henry Mancini composed a song that was played in the movie, Breakfast at Tiffany’s and won the Oscar for Best Original Song. M*ancini *also won the Grammy for Record of the Year (1962) and the song has been covered by many artists. The song: Moon River.
The next total eclipse of the moon occurs on 4 April. The duration of totality is very short: only 12 minutes.
The entire eclipse will be visible from New Zealand and eastern Australia.
Bonnie Tyler’s 1983 hit single, Total Eclipse of the Heart, sold over 9 million copies and as such is one off the best selling singles of all time.
In the novel Gone with the Wind ‘Bonnie Blue’ Butler (formally Eugenie Victoria Butler) is Scarlett’s third child, though her only one with Rhett.
Bonnie is killed when falling from her pony.
The Butlers were one of the most important Anglo-Norman families of Ireland for several centuries, with a finely tuned political sense which allowed them to keep in support of the reigning monarch, acquiring the titles of Earl of Ormonde, Marquess of Ormonde, and Duke of Ormonde.
One of the Butler ladies married into the Boleyn family and was the great-grandmother of Elizabeth I. Later generations of Butlers ascertained which way the political winds were blowing and threw in their lot with William of Orange, being rewarded when he became William III.
Their principal seat was Kilkenny Castle.
The Empress Elizabeth of Russia was known for the extravagance of her attire. She was said to have owned 15,000 dresses and several thousand pairs of shoes.
Former first lady of the Philippines Imelda Marcos owned an estimated 7,500 pairs of shoes. 3,000 pairs of her shoes are in museums in the Philippines. Imelda Marcos is one of the few first ladies to have an assassination attempt made on her life. On 07 December 1972 an assailant tried sttabbing her to death. The assailant was shot to death, while Marcos suffered wounds to her hands and arms that required 75 stitches.
I always liked this use of the phrase: https://www.youtube.com/watch?v=Nmgice3ieZ4
In play:
The Philippines national flag is the only one which is purposefully flown upside-down in wartime. The U.S. flag is supposed to be flown upside-down only to indicate distress or an emergency, but is sometimes thus displayed to make a political point.
Because of its design, It is difficult to tell if the British Union Jack is being flown upside down, so it is not a very reliable indicator of distress. At sea, it would be more likely that the Ensign would be flown upside down, as that is clearly recognisable.
The flag of Alabama today is one of the simplest designs imaginable-a red X on a white field- officially the cross of St. Andrew (and similar to the the official signature of more than a few of the state’s legislators over the years).
The current simplicity offsets the state’s elaborate Secession flag flown during the Civil War: a two sided number with the goddess of Liberty and the phrase INDEPENDENT NOW AND FOREVER on one side and a rattlesnake wrapped around a cotton bush and the phrase NOLI MI TANGERE (vernacular translation “don’t mess with me”) on the other.
Alabama was admitted to the Union in 1819. In 1820 the University of Alabama was founded as The University of the State of Alabama. In 1827, Tuscaloosa was chosen as the site for the university.
