THREAD: Meditations on marriage metaphors in Ruth

The book of Ruth is, of course, a story about a beautiful marriage. But even before the courtship and the wedding and the important genealogy at the end, we find interesting language that is strikingly reminiscent of Genesis 2:24


That important verse reads:

'Therefore a man shall leave [יַֽעֲזָב] his father and his mother and hold fast [וְדָבַ֣ק] to his wife, and they shall become one flesh.'

The verb עזב can be quite strong in force. For example, Joseph leaves behind [וַיַּעֲזֹ֤ב] his garment as he flees from Pharaoh's wife's sexual advances. Countless times, Israel is depicted abandoning the LORD, for example in Judg 2:12 [וַיַּעַזְב֞וּ], and going after other gods.

Likewise, the verb דבק is rather striking. Lot is mortified of disaster overtaking him [תִּדְבָּקַ֥נִי] as he flees from Sodom. Israel is commanded in Deut 10:20 to cling fast [תִדְבָּ֔ק] to the LORD and serve him and swear by his name.

Together they illustrate how radical God designed marriage to be. Marriage is a real severing of family relations in order to form a new, permanent bond with another human being.

Something very similar to this takes places in Ruth's life.

THE BATTLE OF PRATAPGARH (10 Nov, 1659)

Chhatrapati Shivaji Maharaj's impeccable military genius and matchless courage humbled the Adil Shahi Sultanate.

The beginning of what was to come later for the M0ghuls from one of the most indefatigable defenders of Dharma!

(Thread)


Shivaji’s growing influence in Maval region, made him a threat to the Adil Shahi ruler of Bijapur who sought to restrain him. The man who was given the responsibility of this mission, was their commander, Afzal Khan. Afzal was a formidable warrior known for his ruthlessness.(1)

His strategy was to bring Shivaji out into the plains, where he held an advantage, compared to the rocky Deccan terrain. Afzal attacked the holy town of Pandharpur, and later demolished the temple of Bhavani at Tuljapur to instigate Shivaji in a bid to bring him out.(2)

Shivaji was angry but remained patient. Knowing that he could not defeat Bijapuri Sultanate in an open battle, Shivaji moved to Pratapgarh fort, located on rocky heights, surrounded by thick forests of Jawali.(3)

This set the pattern for future Maratha attacks, using guerrilla warfare against larger invading armies rendering them ineffective in unfavorable terrain.(4)

Charles Ponzi and the Postal Service

The story of the man who put the 'Ponzi' in 'Ponzi scheme'

/THREAD/


1/ Carlo Pietro Giovanni Guglielmo Tebaldo Ponzi, a.k.a. Charles Ponzi, was an italian swindler and con-artist.

Born in 1882 in Italy, he became notorious for his money-making fraudulent schemes in North America in the 1920s.


2/ He arrived in Boston in late 1903 with $2.50 in his pocket.

After many professional failures, he moved to Montreal in 1907 and started working as a bank teller at Banco Zarossi, where he rose to the position of bank manager.


3/ This is where he first witnessed the bank's scheme, where Zarossi was funding interest payments using deposits from newly opened accounts instead of investment profits.

4/ Ponzi served 3 years in jail for check forgery and returned to the US after his release.

However, he got involved in smuggling illegal immigrants into the country landing in prison for another 2 years, moving back to Boston after that.

It's now over half a century since 1970, and I'm starting to wonder if we should bring back its concept of gracious modern living...


You see we've grown so used to Swedish-style modernism that we've sort of forgotten that maximalism, rather than minimalism, was once the sign of a cultured abode.


The 1970s in many ways reached back to the rich ideas of Victorian decor: heavy, autumnal and cluttered. Home was meant to be a baroque and sensual experience, rather than a 'machine for living in.'


Gaudy was certainly in by 1970: colour choices for interior design were rich and varied, with every room becoming a boutique of signature design.


Experimentation and adventurism were also coming to the fore: now we had landed on the Moon surely we should start to live like astronauts on Earth.

Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

There are so many firsts in Egypt that we all know about, and that makes Egypt unique. For example, the Sumerians did not build the pyramids of Egypt.

Krugman is, of course, right about this. BUT, note that universities can do a lot to revitalize declining and rural regions.

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

https://t.co/7QIx5CFdfJ


The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

Stan Lee’s fictional superheroes lived in the real New York. Here’s where they lived, and why. https://t.co/oV1IGGN8R6


Stan Lee, who died Monday at 95, was born in Manhattan and graduated from DeWitt Clinton High School in the Bronx. His pulp-fiction heroes have come to define much of popular culture in the early 21st century.

Tying Marvel’s stable of pulp-fiction heroes to a real place — New York — served a counterbalance to the sometimes gravity-challenged action and the improbability of the stories. That was just what Stan Lee wanted. https://t.co/rDosqzpP8i


The New York universe hooked readers. And the artists drew what they were familiar with, which made the Marvel universe authentic-looking, down to the water towers atop many of the buildings. https://t.co/rDosqzpP8i


The Avengers Mansion was a Beaux-Arts palace. Fans know it as 890 Fifth Avenue. The Frick Collection, which now occupies the place, uses the address of the front door: 1 East 70th Street.
