Halloween 2022 on Brandi Circle

 We have dresseed for Halloween in years past. Being in costume makes it fun to give out treats. This year, among a dozen knickknacks, I bought elf years. I am not sure which character that wll be for.

The Werewolf wakes up at 2:30 PM and works until 9:30.
He will be working late for Halloween
.

 

The giant and the dinosaur stand out. 
The Rider and Dragon need some walking around
 to be perceived within the very busy graveyard scene.

We are fixin' to start.


The things that go bump in the night are a little happier in this scene 
across from the werewolf.



Neatness counts. Nicely arrayed.

With the mortgage meltdown and stock market collapse of 2008, 
I gave stock certificates to the adults in costume.

The Solstice Seasons

“‘Tis the season to be jolly…”  It was easy enough to note the shortest day as the longest night. But the earliest sunset and latest sunrise are several days different from the solstice. In fact, it makes sense to celebrate the Winter Solstice Season (“Christmas”) from December 8 (“St. Nicholas Day”) to January 4 (no best feast day there). On the other side of the year, Summer Solstice would be from June 10 to July 1, call it Flag Day to Independence Day on the civil calendar.

Our New Year comes from Rome during the dictatorship of Gaius Julius Caesar. As farmers, the old Romans had started their year in March.The two winter months had no names. They were dead times. It is why we still call the ninth month by the name of the seventh: “September.” Julius Caesar courted Cleopatra Ptolemy and sought to unite Rome and Egypt. He moved New Year’s Day to January 1.

It may be that the heliacal rising of Sirius marked the flooding of the Nile and the start of a new year only about the time of Claudius Ptolemy (100 to 160 CE). The Nile rises because of monsoon rains in Ethiopia. The waters move down the Blue Nile and White Nile. It is not precise, not astronomical. As we know, the climate changes; weather is variable. 
“In this paper the question of prediction of the Nile flood based on the first morning visibility of Sirius is considered. It is shown that the only text that describes this event is formulated very vaguely. It makes impossible to derive a reliable astronomical dating. Modern interpretations of this text are based on the free interpretation of the original source, and often do not match. According to historical evidence of Greek authors and later Egyptian texts, flooding of the Nile based on heliacal rising of Sirius could be predicted at the beginning of [the first] millennium AD. This fact is confirmed by astronomical calculations.”  (From “Heliacal rising of Sirius and flooding of the Nile” by Nickiforov, M. G. and Petrova, A. A. in Bulgarian Astronomical Journal, Vol. 18, No. 3, p. 53 archived at the Astrophysics Database at Harvard here.
For the Celts, New Year’s was harvest time, Samhain, what we call Halloween. In some places in medieval Europe, New Year's Day was May Day. During a warming period, New Year's Day  became the Vernal Equinox: the first day of spring. Easter is still tied to Passover: the first Sunday after the first full moon after the first day of Spring. Those who kept the old calendar were “April Fools.” Correlating the lunar and solar calendars and marking those over centuries gave rise to modern astronomy. In any case, it was Julius Caesar who made January 1 New Year’s Day. It marked the close of the Saturnalia solstice celebrations. 
 
Earliest sunrise latest sunset near solstice (Washington Post here)

A few years ago, I was working as a security guard and it was late March or early April. Three of us were walking a shift change about 6:00 PM. One guy was an Army brat who had lived around the world, a lot of it in Scotland. The other guy grew up here in Austin. We stepped outside. After about ten days of rain, the sky was clear. “Hey, look,” I said, “the sun is still up.” The guy from Austin was taken aback. “What do you mean?” he said. “The sun goes down the same time every night.” Well, in Austin, it mostly does, but not where I’m from and surely not in Scotland.

Reminders of Newtonmas Past

Newtonmas 2011
Today, we ignore his religious writings, the extent of which actually eclipsed his scientific production.  His heretical Arian beliefs foreshadowed modern Unitarianism, but he swore under oath to be a Trinitarian so that he could teach at Cambridge. 

Newton’s colleagues called him fearful, cautious, suspicious, insidious, ambitious, excessively covetous of praise, and impatient of contradiction. Even his relatives and his true friends were modest in their praise of Newton. Physically sound in his life, he died at 84. He had lost only one tooth, still had much of his hair, and read without glasses. Yet, he was a hypochondriac, suffering from illnesses and diseases that he treated with medicines he made for himself.  

Newtonmas 2012
The English crown turned to him to save the Royal Mint. Even when they were not corrupt - which they usually were - the Mint officials were unable to solve the basic problem of creating and maintaining a system of money that worked. A stern Protestant, deeply religious, and moralistic in the extreme, Newton cleared out the criminal element and gave England a reliable monetary system.

Newton and the Counterfeiter: The Unknown Detective Career of the World’s Greatest Scientist by Thomas Levenson (Houghton Mifflin Harcourt, 2009) is intended for a general readership, yet rests on an extraordinary foundation of careful scholarship.  Thomas Levenson teaches science journalism at MIT.  He has been granted several awards for his PBS documentaries. Levenson delivers to print the videographer’s impact of sight and sound.  You walk down the alleys and into the pubs where Isaac Newton investigated crimes against the Mint of which he served as warden and later master.

Newtonmas 2013
Nature and nature's laws lay hid in night;
God said, 'Let Newton be'  and all was light.
Alexander Pope

Sir Isaac Newton was born on Christmas Day 1642, the year that Galileo died.  For most people, Newton is famous for his Three Laws of Motion.  Beyond that, those with additional education know him for creating the Calculus to prove his theories of celestial and terrestrial mechanics. In addition, Newton invented the reflecting telescope as a result of his experiments with light.  And he also proved the general case for the Binomial Theorem (“Pascal's Triangle”). He served in Parliament, representing Cambridge, where he had been a professor of mathematics.  He served as president of the Royal Society of scientists. Few people except numismatists know him to have been the Warden and Master of the British Royal Mint for thirty years.  He had himself sworn as a justice of the peace so that he could pursue and prosecute counterfeiters.  Any one of those achievements would have made important to us today. That he accomplished all of that - and more - set Sir Isaac Newton apart even from the geniuses and polymaths recorded by history.

Newtonmas 2014
I offered Newtonmas in a radio script for WKAR-FM East Lansing in the early 1980s (1982-1984).  In that script, I built up the imagery of a little boy born in a small village across the sea who would grow up to bring light to the world.  When I cited the poet, I emphasized the word Pope – and then announced that Sir Isaac Newton was born on December 25, 1642, the same year that Galileo died. 

Over the years, I sometimes sent out "Newtonmas cards" to our friends, most of whom we knew from college classes in computer science and related fields.  Our physics professor, Alan Saaf, occasionally called the McDonald’s Quarter Pounder a “Newton Burger” (1.0 N ~ .224 lb-f). I do not recall Dr. Saaf ever saying “Newtonmas” but he could have.

Newtonmas 2015
We commonly call the Nativity scene “the first Christmas” though it was not. The first Christ Mass could not have been celebrated before the Church existed. So, too, did the first Newtonmas not come until 248 years after his birth.
 
It seems that three students at Tokyo University started Newtonmas in their dormitory sometime before 1890.  As the undergraduates developed into graduates and assistants, their professors were drawn into the celebration, and a more suitable assembly hall was found in the University Observatory.  By 1890, they called themselves the Newtonkai  (Newton Association; çš† = kai = “all”) and moved to the Physical Laboratory. There, they played games symbolic of great mathematicians, physicists, and astronomers: Newton’s apple, Franklin’s kite, a naked doll for Archimedes … 

That story comes from “A New Sect of Hero-Worshippers” published in Nature, Vol. 46, No. 1193, p. 459, 8 September 1892. It available from the publisher for $18 if you are not a member, or it can be found online at Google Books.

Mardi Gras Doubloons Celebrate Life

Mardi Gras is the last party before Lent. In New Orleans, among other kinds of trinkets such as necklaces, the krewes of floats throw doubloons. 
From left to right: 
American Ingenuity, Atlas, Triumphs of Arts and Sciences, Love that American Money
One side announces the krewe. The other usually is in line with a theme for the year. Many of the krewes are named for pagan gods and goddesses. Many are anodized for the liturgical colors of Easter: white, gold, red, green, and purple. They also can be found in blue, etc.


Coin of the Realm, Inventions and Discoveries, The Sciences
As my username is often "Mercury" I have a lot of those, as well as his analogs, Hermes and Thoth. 
All Things Beautiful and the Krewe of Pegasus
I also have Atlases. Overall, having bought mixed lots from dealers over the years, I have assembled a box of good wishes, celebrations, and honors that are meaningful to me.  They make nice hand-outs at parties and meetings, especially among my Objectivist friends.
