What's A Leap Second?

Screenshot of the UTC clock from www.time.gov during
 the leap second on December 31, 2016.
Every now and then a leap second is added to Coordinated Universal Time (UTC) in order to synchronize clocks worldwide with the Earth's ever slowing rotation.

Atomic Time vs. Universal Time - two components are used to determine Coordinated Universal Time (UTC):

International Atomic Time (TAI): A time scale that combines the output of some 200 highly precise atomic clocks worldwide, and provides the exact speed for our clocks to tick.

Universal Time (UT1), also known as Astronomical Time, refers to the Earth's rotation around its own axis, which determines the length of a day.

Here're some excerpts from WhatIf's excellent explanation - go there and read the whole thing:
Half a billion years ago (when the Earth was 4 billion years old, instead of 4.5), each day was 22 hours long instead of 24. The day has gotten longer because of tidal forces from the Moon.
Loosely speaking, here’s how tidal drag works: The Moon’s tides raise bulges in the Earth, but the Earth’s rotation moves those bulges out of line with the Moon. The Moon’s gravity tries to tug the bulges back into line, which exerts a twisting force on the Earth, slowing it down.
Strangely, the Earth is actually not slowing down as much as you’d expect from tidal drag. The biggest reason for the discrepancy is that during the last ice age, the continents were pushed down by the weight of the glaciers, and they’re still springing back into place. This has the effect of shifting mass toward the poles, closer to the axis of rotation: 
At the moment, each day is about 0.8 milliseconds longer than the 86,400 seconds it needs to be to avoid adding leap seconds.
This difference fluctuates over time based on weather and other effects (it’s actually shortened a bit since the early 1990s), although in the long run, it will definitely get larger as the Earth slows.
If we wanted to get rid of leap seconds, we’d need to keep the Earth spinning at a more constant rate. This means speeding up the Earth and shortening each day by about 0.8 milliseconds. 

This is a tough problem. Here are a few things that won’t work:

Spinning counterclockwise in a chair. It temporarily alters the Earth’s rate of rotation, but not enough to matter.

Putting rocket engines on the Equator. This won’t work because the exhaust would go into the atmosphere, which transmits the force back to the ground as wind drag—it’d be like making a bike go forward by pushing on the handlebars. If the engines were somehow mounted above the atmosphere, they’d be able to slow the Earth, but not by enough to accomplish our goal.

Triggering big earthquakes. This can alter the length of the day, but even those aren’t big enough to make a difference.

In the end, there’s only one solution: Hitting the Earth with asteroids.
More science, from TimeandDate.com:
A normal day has 86,400 seconds, but in the atomic time scale 1 second is not defined as one 86,400th of the time it takes Earth to rotate around its axis but rather as the time it takes a Cesium-133 atom at the ground state to oscillate precisely 9,192,631,770 times.

The advantage of this definition is that it is extremely precise: atomic clocks deviate only 1 second in up to 100 million years. On the other hand, the Earth's rotation, which is expressed by the time standard UT1, is far less reliable. It slows down over time, which means that days get longer. On average, an Earth day is about 0.002 seconds longer than the daily sum of the 86,400 seconds measured by the atomic clocks. This makes for a discrepancy between TAI and UT1 of around 1 second every 1.5 years.
Leap seconds are added to our clocks (UTC) so this discrepancy does not get too large over time and the time we use is synchronized as much as possible with the Earth's rotation.
When the difference between UTC and UT1 approaches 0.9 seconds, a leap second is added to UTC and to clocks worldwide. By adding an additional second to the time count, our clocks are effectively stopped for that second to give Earth the opportunity to catch up with atomic time.

December 21 is the winter solstice, the shortest day of the year

In the Northern Hemisphere the December solstice (wiki) marks the longest night and shortest day of the year with the latest dawn and the sun at its lowest point in the sky. I seem to remember that when I was a kid, the first day of each new season was always considered to be the 21st (of March for Spring, June for Summer, September for Autumn, and December for Winter). I guess it's more accurate now.

In seed-time learn, in harvest teach, in winter enjoy. ~William Blake

Winter is the king of showmen,
Turning tree stumps into snowmen
And houses into birthday cakes
And spreading sugar over lakes.
Smooth and clean and frosty white,
The world looks good enough to bite.
That’s the season to be young,
Catching snowflakes on your tongue.
Snow is snowy when it’s snowing,
I’m sorry it’s slushy when it’s going.

~ Ogden Nash

I wonder if the snow loves the trees and fields, that it kisses them so gently? And then it covers them up snug, you know, with a white quilt; and perhaps it says "Go to sleep, darlings, till the summer comes again.


What good is the warmth of summer, without the cold of winter to give it sweetness.

~ John Steinbeck, Travels with Charley: In Search of America

“Nothing burns like the cold.”

~ George R.R. Martin, A Game of Thrones

That time of year thou mayst in me behold
When yellow leaves, or none, or few, do hang
Upon those boughs which shake against the cold,
Bare ruin'd choirs, where late the sweet birds sang.
In me thou seest the twilight of such day
As after sunset fadeth in the west,
Which by and by black night doth take away,
Death's second self, that seals up all in rest.
In me thou see'st the glowing of such fire
That on the ashes of his youth doth lie,
As the death-bed whereon it must expire
Consumed with that which it was nourish'd by.
This thou perceivest, which makes thy love more strong,
To love that well which thou must leave ere long.”

~ William Shakespeare, Sonnets

Nature has many scenes to exhibit, and constantly draws a curtain over this part or that. She is constantly repainting the landscape and all surfaces, dressing up some scene for our entertainment. Lately we had a leafy wilderness; now bare twigs begin to prevail, and soon she will surprise us with a mantle of snow. Some green she thinks so good for our eyes that, like blue, she never banishes it entirely from our eyes, but has created evergreens.

Henry David Thoreau, Walden

The winter solstice (wiki) produces the shortest day of the year in the northern hemisphere, when darkness descends over the land to its greatest extent. For centuries, humankind has greeted the solstice with mixed emotions - with fear that the darkness might not really recede; and with hope that the cycling of the seasons would again reassert itself. 

Of the winter season, American poet Ezra Pound (1885-1972) complained,

"Winter is icumen in,
Lhude sing Goddamn,
Raineth drop and staineth slop,
And how the wind doth ramm!
Sing: Goddamn."*

* N.B. This is actually a parody of an anonymous 13th-century English song:
"Sumer is icumen in,
Lhude sing cuccu!
Groweth sed and bloweth med,
And springeth the wude nu.
Sing cuccu."
Here's a brief explanation on the mechanics of solstices and equinoxes:



And a two minute NatGeo video:


The two revolutions, I mean the annual revolutions of the declination and of the centre of the Earth, are not completely equal; that is the return of the declination to its original value is slightly ahead of the period of the centre. Hence it necessarily follows that the equinoxes and solstices seem to anticipate their timing, not because the sphere of the fixed stars moves to the east, but rather the equatorial circle moves to the west, being at an angle to the plane of the ecliptic in proportion to the declination of the axis of the terrestrial globe.


Also at this time of year:

Saturnalia (wiki):

The winter solstice festival Saturnalia began on December 17 and lasted for seven days in In Ancient Rome. These Saturnalian banquets were held from as far back as around 217 BCE to honor Saturn, the father of the gods.

Saturnalia by Antoine-Francois Callet (1741-1823) Musée du Louvre
The holiday was celebrated with a sacrifice at the Temple of Saturn, in the Roman Forum, and a public banquet, followed by private gift-giving, continual partying, and a carnival atmosphere that overturned Roman social norms.

The festival was characterized as a free-for-all when all discipline and orderly behavior was ignored.

Wars were interrupted or postponed, gambling was permitted, slaves were served by their masters and all grudges and quarrels were forgotten.

The Saturnalia would degenerate into a week-long orgy of debauchery and crime – giving rise to the modern use of the term 'saturnalia', meaning a period of unrestrained license and revelry. A mock 'king' was even chosen from a group of slaves or convicts and was allowed to behave as he pleased for seven days (until his eventual ritual execution).

Halcyon Days (wiki):

The seven days preceding, and the seven days following the shortest day, or the winter-solstice, were called by the ancients the Halcyon Days. This phrase, so familiar as expressive of a period of tranquility and happiness, is derived from a fable, that during the period just indicated, while the halcyon bird or king-fisher was breeding, the sea was always calm, and might be navigated in perfect security by the mariner. The name halcyon is derived from two Greek words: the sea & to conceive; and, according to the poetic fiction, the bird was represented as hatching her eggs on a floating nest, in the midst of the waters. Dryden thus alludes to the notion:

'Amidst our arms as quiet you shall be,
As halcyons brooding on a winter's sea.'

A movie is being made about Dunkirk - here's the trailer

The evacuation of large elements of the British and French armies from Dunkirk (wiki) on the French coast, which took place during the period from May 26 through June 4, 1940, followed their defeat by the German blitzkrieg that overwhelmed France during the early months of World War II. The sudden German attack through Belgium on May 10 had quickly rolled up the French and British left wing and surrounded it in a small enclave on the English Channel opposite Dover. 

In a largely improvised but brilliantly executed maritime operation that mustered both the Royal Navy and civilian small craft of every kind, nearly 340,000 British and French troops - nearly 90 percent of those invested - were ultimately withdrawn, despite incessant German armored and air attacks.

Dunkirk was, of course, the inspiration for Winston Churchill's "We shall fight on the beaches...we shall never surrender" speech:
We shall not flag or fail. We shall go on to the end. We shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing in the air, we shall defend our island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.

The entire internet.
Wikipedia's slightly clearer version of the same map used by @workergnome

In the very early years of the Internet, it was the secret and very small ARPANET (wiki) - it had started in the late 1960s, with just four locations (map, right). 

Arpanet's original 4 locations, via @gadgetopia
By 1973, it had expanded to a small handful of government labs, research universities, and private companies, but still so few that the entire network could be mapped on a single sheet of paper.

Recently, Newbury found the map above among his dad’s papers and posted it online. You can find Stanford, UCLA, Utah and UCSB, the original members, but by 1973, ARPANET had expanded east, to Case Western, Carnegie Mellon, Harvard, and MIT. There are government labs, like Lawrence Berkeley National Lab and the Army’s Aberdeen Ballistic Research Lab, and private research organizations like MITRE and Xerox. 

The map Newbury found was printed in a report from the NASA Ames Research Center, which also included this map, showing the geographical spread of the network:

And by 1977, there was this, which claimed it was based on the “best information obtainable”. Larger version here.

New Guinness record-setting Rube Goldberg machine takes 412 steps to light a Christmas tree

A new Guinness world record-setting Rube Goldberg machine (wiki) just in time for Christmas - watch the municipal Christmas tree in Riga, Latvia, get switched on by a process requiring 412 steps and 10 minutes to complete (the video is condensed), bettering the previous record of 382 steps achieved in Hungary back in April 2015. The company Scandiweb sponsored the record-setting chain reaction that Guinness has enshrined as the World's Largest Rube Goldberg Machine

The principle of a Rube Goldberg machine (wiki) is to complete a simple task in the most complicated way possible. This attempt featured a diverse range of devices including traditional parts like wheels, levers and balls, as well as more unusual items like a fan and coffee maker.
 
The finale was initiated by a sound meter that was triggered by the shouts and screams of the guests.

Pretend To Be A Time Traveler Day


Pretend To Be A Time Traveler Day was created in 2007 by a now defunct (as far as I can determine, anyway) conglomerate of webcomics called Koala Wallop*. Here's Wired at the time:

Saturday, December 8th has been declared "Pretend to be a Time Traveler Day."  The whole idea is to pretend for the day that you are a traveler from a different time – except that, of course, you can’t actually *tell* people you’re a time traveler, because they’ll think you’re crazy.  There are, of course, options as to how a traveler from a certain other time might act:

Utopian/cliché Future –

If the Future did a documentary of the last fifty years, this is how badly the reenactors would dress. Think Star Trek: TNG or the Time Travelers from Hob. Ever see how the society in Futurama sees the 20th century? Run with it. Your job is to dress with moderately anachronistic clothing and speak in slang from varying decades. Here are some good starters:

– Greet people by referring to things that don’t yet exist or haven’t existed for a long time. Example: "Have you penetrated the atmosphere lately?" "What spectrum will today’s broadcast be in?" and
"Your king must be a kindly soul!"

– Show extreme ignorance in operating regular technology.  

Dystopian Future

This one offers a little more flexibility. It can be any kind of future from Terminator to Freejack. The important thing to remember is dress like a crazy person with armor. Black spray painted football pads, high tech visors, torn up trenchcoats and maybe even some dirt here or there. Remember, dystopian future travelers are very startled that they’ve gone back in time. Some starters:

– If you go the "prisoner who’s escaped the future" try shaving your head and putting a barcode on the back of your neck. Then stagger around and stare at the sky, as if you’ve never seen it before.

– Walk up to random people and say "WHAT YEAR IS THIS?" and when they tell you, get quiet and then say "Then there’s still time!" and run off.

– Stand in front of a statue (any statue, really), fall to your knees, and yell "NOOOOOOOOO"

– Stare at newspaper headlines and look astonished.

– Take some trinket with you (it can be anything really), hand it to some stranger, along with a phone number and say "In thirty years dial this number. You’ll know what to do after that." Then slip away.

The Past

This one is more for beginners. Basically dress in period clothing (preferably Victorian era) and stagger around amazed at everything. Since the culture’s set in place already, you have more of a template to work off of. Some pointers:

– Airplanes are terrifying.  Also, carry on conversations with televisions for a while.

– Discover and become obsessed with one trivial aspect of technology, like automatic grocery doors. Stay there for hours playing with it.

– Be generally terrified of people who are dressed immodestly compared to your era. Tattoos and shorts on women are especially scary.

If anyone gives this a try, report back to the class and let us know how it went. ;-)

I think this is one of the original comics - larger version here.

December 6 is the feast day of St. Nicholas of Myra, aka Santa Claus

His eyes - how they twinkled! His dimples: how merry,
His cheeks were like roses, his nose like a cherry;
His droll little mouth was drawn up like a bow,
And the beard of his chin was as white as the snow;

The stump of a pipe he held tight in his teeth,
And the smoke it encircled his head like a wreath.
He had a broad face, and a little round belly
That shook when he laugh'd, like a bowl full of jelly. 

~Clement C. Moore (1779-1863) ("A Visit from St. Nicholas," excerpt*) 

The giver of every good and perfect gift has called upon us to mimic God's giving, by grace, through faith, and this is not of ourselves.

~ St. Nicholas of Myra (attributed) 

Once again St. Nicholas Day
Has even come to our hideaway;
It won't be quite as fun, I fear,
As the happy day we had last year.
Then we were hopeful, no reason to doubt
That optimism would win the bout,
And by the time this year came round,
We'd all be free, and safe and sound.
Still, let's not forget it's St. Nicholas Day,
Though we've nothing left to give away.
We'll have to find something else to do:
So everyone please look in their shoe!?

~Anne Frank (1929-1945) (The Diary of a Young Girl, 6 December 1944) 

Give all thou canst; high Heaven rejects the lore
Of nicely-calculated less or more.

~William Wordsworth (1770-1850) ("Tax Not the Royal Saint") 

December 6 is the feast day of Saint Nicholas of Myra (270-343) (wiki), perhaps better known in his latter-day guise as Santa Claus. Born to Greek Christian parents in Palmyra in southern Anatolia, Nicholas was renowned for his great piety at an early age and eventually became the bishop of nearby Myra in what is now Turkey.

St. Nicholas saving the three poor girls and their father
He is known to have attended the Emperor Constantine's First Council of Nicea (325), where he took a strong stand against Arianism, but very little else is certain about his life. On the other hand, a rich body of legends has grown up around his name, largely for working many miracles and his life-long propensity for gift-giving.** Most famously, he is said one night to have thrown three small bags of gold through the window of a poor man as doweries for his three daughters, thus saving them from a life of prostitution.***  On another occasion, he abated a fearsome storm at sea, and thus has been adopted as the protector of sailors and fishermen. 

In 1087, half of his remains were purloined from Myra by sailors from southern Italy and enshrined in the basilica of San Nicola in Bari, where they remain today, the object of great veneration. (The other half of his bones somehow found their way to Venice.) Generally portrayed with his bishop's robes and regalia, Saint Nicholas is one of the most popular saints in both the Catholic and Orthodox traditions and is regarded as the protector of sailors, children, merchants, pawnbrokers, and students, particularly in Greece, Russia, and eastern Europe. 

Facial reconstruction
In the 1950s, the bones were removed while the crypt was spruced up. While they were out, the Vatican asked an anatomy professor at the University of Bari to take thousands of minutely detailed measurements and x-rays of the relics. Flash forward to the present day, and another University of Bari expert, forensic pathologist Francesco Introna, decided to commission an expert facial anthropologist, Caroline Wilkinson of the University of Manchester in England, to reconstruct the saint's face and head using the new technology and the earlier measurements.

* There have been some questions raised about the authorship of this poem - this article sums up the controversy.

** N.B. Thus, his re-branding in the European tradition as Santa Claus, a derivation of his name in Dutch: Sinterklaas

*** The three-ball symbol of the pawn shop is said to derive from these three bags of gold. 

Here's a brief biography/documentary:
