Faces of Guangyuan. Here are some (previously unseen) photographs from late-nineteenth century Sichuan, China. They come from the unpublished journals of missionary Florence Beauchamp, and I’ll add some more when I can. [1/?]

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.

Save as history

I doubt there are many outside of Norway that know that the Norwegian pop group A-ha was critical in the introduction of electric car incentives in Norway. I certainly didn't. Read on...

In 1989, two members of the group, Morten Harket and Magne Furuholmen were in Switzerland with environmentalist Frederic Hauge, when they came across a hobby-converted Fiat Panda. Stated range: 45 km. They snapped it up and imported it to Norway.

On arrival in Norway, the regs didn't accommodate the registration of electric cars so it couldn't legally be driven on the road. Since it had a propane-fuelled heater, just like a motorhome, they registered it as a motorhome.

Moreover, in contrast to petrol cars, diesel cars paid registration fees based on how far they were driven, and our heroes thought this should also apply to electric cars. So the two-seater Swiss-converted Fiat Panda was registered as a diesel motorhome in Norway.

They managed (somehow) to avoid paying the one-off registration fee in 1990, and ever since then electric cars have been exempted this now-substantial fee.

1. This is a thread about the Bristol Beaufighter & how it was the most important (if not the absolute ‘best’) heavy fighter of the SWW. Beaufighter origins go back to the Bristol Type 142 ‘Britain First’ built as a publicity stunt for Daily Mail owner Lord Rothermere in 1935.

2. With a top speed of 278mph, this was considerably faster than the Hawker Fury, which could only manage 207mph. A specification for a fast medium bomber was issued for a revised version of the 142M, named the Blenheim.

3. By the time the war started all-metal monoplane fighters had eclipsed the performance of the Blenheim. Serious shortcomings in operational capabilities of all RAF aircraft were revealed during early wartime aerial activity, leading to heavy losses of aircraft & crews.

4. Lack of defensive armament, armour & self-sealing tanks were added to the problems of looming obsolescence. The huge number of aircraft ordered from shadow factories, along with delays to replacement models, kept the Blenheim in the front line much longer than it should have.

5. Fighter Command had 7 Blenheim IF squadrons at the outbreak of war. These were dual purpose day/night units, but by early 1940 were operating primarily as night fighters. The need to provide cover for east coast convoys led to the formation of 4 ‘trade protection’ squadrons.

You think the Gamestop short squeeze is the greatest ever? Not. Even. Close.

This is the story of Piggly Wiggly and one man taking on Wall Street ALONE.

Buckle up, because this is one of the craziest stories in investment history.

It all started in 1919 when a man by the name of Clarence Saunders invented the first modern supermarket—Piggly Wiggly stores.

Before this time, people had to go into a store, give the clerk a shopping list, and then wait for their items to be gathered and brought out.

Saunders changed all that when he created a retail self-service market where people could pick the items themselves and pay on the way out.

People loved the idea so much that within 3 years there were over 1,200 Piggly Wiggly stores in the U.S.

With this success, Saunders began licensing the Piggly Wiggly name out to other retailers.

Unfortunately, some of these retailers in the northeast began going out of business in the fall of 1922, all while using the Piggly Wiggly name.

Traders on Wall Street heard of these closings and decided that they had an opportunity on their hands.

They began shorting Piggly Wiggly while also spreading rumors that the parent corporation was in trouble.


Within a week the price dropped from $50 to $40 a share.

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
