On 23 September 1984 the BBC broadcast the apocalypse: the story of nuclear war and its effects on the people of Sheffield. Filmed on a shoestring budget it still causes nightmares to this day.

This thread is not for the squeamish.

This the story of Threads...

In the shadowy corners of the shortwave spectrum lurk the Numbers Stations: strange radio broadcasts of mysterious blocks of numbers in creepy monotone voices!

It's actually an old form of spycraft which is still in use today. And as it's #WorldRadioDay let's take a listen...

A Numbers Station is a type of one-way voice link for sending information to spies in foreign countries.

Operating on Short Wave radio bands they transmit a secret code of spoken numbers. Use of Numbers Stations peaked during the Cold War, but some are still operating today.

Numbers Stations are operated by various national intelligence agencies. At set times on a pre-arranged frequency a musical tone is played, followed by a speech synthesised voice reading out blocks of numbers. To most listeners it sounds both creepy and meaningless.

However to spies it can be vital. The numbers can be decoded to reveal a message, provided the spy has the right One Time Pad (OTP) - a random number key that is only used once before it is destroyed. OTP encryption is impossible to break if done correctly.

Why broadcast your secret message on Short Wave? Because it can be picked up across the globe. All a spy needs is a shop bought SW radio, a pencil, and the correct One Time Pad and they - and only they - can decipher the message. No complex kit is required.

Now many readers have asked me over the years "how do I (with my great hair) go about fleeing a gothic house?"

That's a very good question, because it's not as easy as it seems...

There are of course many gothic domiciles that women with great hair can flee from:
- a house
- a mansion
- a castle
- a chateau

More adventurous gothic heroines can also choose to flee:
- a manor
- a keep
- a graveyard
- some dark foggy towers

As gothic houses come in all shapes and sizes you may come across the following things which require fleeing:
- Strangers (call a taxi)
- Tombs (walk to the nearest exit)
- Hell (fleeing recommended)
- Darkest Death (head start required)

There are some items that are a clear giveaway that you are in, or near, a gothic house that requires fleeing. Look around you and see if you can spot:
- sarcophagi
- crucibles (unless in a chemistry lab)
- anemones
- any form of ides

THE LAST PRINCESS OF LAHORE - BAMBA DULEEP SINGH (1869 - 1957)

Thread

Post partition, every morning a weak old woman would board the Model Town bus service headed to the city. The conductor never asked her for money or he would invite anger of the last Queen of Punjab.

1/n

Princess Bamba Sutherland, the eldest daughter of Maharaja Duleep Singh and grand-daughter of Maharaja Ranjit Singh, was born on Sep 29, 1869, in London.

Duleep Singh, the last Maharaja of Punjab was taken away to England by British after annexing Punjab.

Since he was still a child he was forcibly converted to Christianity and made to adopt British values in order to prevent him from ever thinking about regaining Punjab.

He was also kept away from his mother Maharani Jindan.

We will likely never be able to establish with certainty the identity of the two Black men painted by Rembrandt. There are no documents found, linking the painting to individuals. But we can make a reasoned guess. #BlackHistoryMonth #day20 #rembrandt #identification

First there is the problem of the date. The inventory with a reference to 'two Moors in one painting' was drawn up in 1656 in what is now the @Rembrandthuis; however, the painting that hangs in the @Mauritshuis bears not only Rembrandt’s signature but also the year 1661.

Was the painting made in 1656 while Rembrandt was still living and working in Jodenbreestraat, and not signed and sold until 1661, when he had moved to the Jordaan district? The 1656 estate inventory suggests this.

On the other hand, it is of course possible that Rembrandt painted several pictures featuring two black men. Nevertheless, supposing that it is one and the same
painting, then we can assume that the two men
were in the studio in Jodenbreestraat to be portrayed in or before 1656.

Of course there still are dozens of candidates, since there was a small Black community in the area. However, it is striking, and exceptional, that two men are portrayed instead of one, as was customary in this genre.

The Kushana Empire was founded by Mahārājādhirāja Kujula Kadphises, a Shaivite Hindu convert from his ancestral Steppe religion of the Yüeh-chih. He was not a Buddhist, as popularly believed.

A thread on the Hindu Emperors of the Kushana Dynasty.

The Kushanas were part of a tribal confederation called the Yüeh-Chih that originally lived in the western part of the Gansu Province of China. They were pushed west by the invasions of the Xiongnu (Huna) confederation. Kuja Kadphises united all the five sub-tribes under Kushana.

Emperor Kuja Kadphises had converted to Shaivism, a Mathura inscription from the Tōkrī Tīla mound (Maṭ village) clears up previous confusion (Based on him being called "satyadharmasthita" or 'steadfast in the true dharma' people speculated he was a Buddhist)

This is incorrect.

The Mathura inscription applied the same epithet to Emperor Huvishka (satyadharmasthita) but explicitly says the Kingdom was conferred upon its founder by Lord Shiva (Sarva is the epithet of Shiva). This makes it clear Kujula Kadphises had adopted Shaivism & the Kharoshti script.

This also makes sense, when we realize his son, Emperor Vima Kadphises was also a devoted Hindu Shaivite (and in his coins we clearly see a trishulin ithyphallic shiva with a tiger skin).

So his son had just been continuing his father's tradition & upbringing.

Today is Holocaust Remembrance Day (a thread and history lesson)

In 1919 a young World War I veteran electrified a dissatisfied and bitter populace with his speeches in the beer halls of Bavaria

His name was Adolf Hitler

His ideas would lead to 50M dead across Europe
1/25

Hitler as an orator spread a message against communism, socialism, non-traditional ideas, and increasingly the Jewish people

He believed that a conspiracy of leftist, led by the Jewish people sold out Germany in World War I, preventing victory

2/25

Anton Drexler started the German Worker's Party or DAP, in 1918

In 1919 he wanted to rename it the German Socialist Worker's Party but a young Hitler objected to the name socialist being included

Drexler wanted to add the name to garner support with the middle classes

3/25

The DAP was rooted in the concept of an Aryan master race, anti-Semitism, anti-Marxism, was against the World War I armistice, and believed Germany could have won the war

All of these ideas appealed to Hitler, who also believe Germany could have won WWI

4/25

Among Hitler's earliest followers, Hermann Goering heard Adolf speak for the first time in 1919

Goering was a World War I hero and had liked wearing his uniform

He was badly beaten in late 1918 by a group of Communists, the injuries left him a drug addict

Why are loops called "loops"?

(0/15)

Before addressing the question in the title tweet, let me first back up to the origin of the term "quasigroup". The first use of the term was by Ruth Moufang in 1935 in her study of the multiplicative structure of the octonions.

(1/15)

Moufang defined "quasigroup" in a much narrower sense than we do now. The details are not part of this story, so I'll skip them. What she called quasigroups we now call Moufang loops in her honor.

(2/15)

The current definition of quasigroup - a set with binary op * s.t. for all a,b, the equations a*x=b, y*a=b have unique solutions x,y - is due to Hausmann & Ore (1937), in the same paper where they introduced the "other" meaning of "groupoid": a set with a binary operation

(3/15)

It was A.A. Albert (1943) who introduced the term "loop" for a quasigroup with identity element. In his words, "It will be very convenient to have a special name for such quasigroups..." (p.510)
