1. Like Nnamdi Azikiwe, Patrice Lumumba was the independence leader & the first Prime Minister of the DRC. He was a pan-Africanist, an African nationalist, & the casualty of the US-Soviet Cold War. He was first deposed by Mobutu Sese Seko in 1960, with support from US & Belgium.

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.

So when it first appeared in Normandy, the Sherman Firefly and it's meaty 17 pounder represented an ideal combo of reliable chassis, great gun and devastating firepower right?

Ummm...

Truth is a bit more complex. /1
#WW2 #SWW #History

Deliveries of Firefly to units only commenced in April 1944,
just a few weeks before Overlord & left minimal time for familiarisation.

Armoured Regiments mostly utilised Fireflies on a basis of 1 per troop of 4 tanks. /2

Finally each armoured regiment troop had access to integral, meaty, anti-tank firepower capable of dealing serious damage to any German AFV likely to be encountered. /3

The dual purpose 75mm gun was quite capable of laying down a reasonable HE shell or AP round for dealing with Panzer III or IV.

Firefly's 17 Pounder had.... problems with HE, but excelled at tank killing. So Tigers and Panthers would need to be wary. /4

Firefly's design history dated back to March 1943 when the General Staff published "Policy on Tanks" which effectively stated the majority of tanks should have a good HE weapon and...

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.

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)

In this thread, I will argue that the conventional wisdom that Shannon's information theory is all about syntax and not about semantics stems from superficial reading. On the contrary, even his 1948 BSTJ paper is already concerned with syntax, semantics, *and* pragmatics. 1/14

Of course, it does not help matters that Shannon himself states that "semantic aspects of communication are irrelevant to the engineering problem" of communication on the first page of his paper. But you have to read the entire paper, not just the first page. 2/14

Let's first pin down the notions of syntax, semantics, and pragmatics in the sense of Charles Morris: syntax is about relation of symbols to other symbols, semantics is about their relation to objects, and pragmatics is about their relation to subjects. 3/14

Let's start with pragmatics. The full formulation of Shannon's theory is concerned with the problem of reliable communication of some state of the world over a noisy medium, subject to a fidelity criterion. This is an operationalist, pragmatist concern. 4/14

We may envision the problem where we take an action U contingent on the state of the world X and incur the cost c(X,U). We cannot access the state of the world directly, but must mediate the act of selecting the action through transmission of symbols over a noisy channel. 5/14
