Hellburners (Dutch: hellebranders) were specialised fireships used in the Siege of Antwerp (1584-1585) during the Eighty Years’ War between the Dutch rebels and the Habsburgs. They were floating bombs, also called “Antwerp Fire”, and did immense damage to the Spanish besiegers. Hellburners have been described as an early form of weapons of mass destruction.

The Great Smog of London, or Great Smog of 1952, was a severe air-pollution event that affected the British capital of London in early December 1952. A period of cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday, 5 December to Tuesday, 9 December 1952 and then dispersed quickly when the weather changed.

A memorial recognising the wartime work done by Quakers has been unveiled at the National Memorial Arboretum in Staffordshire.

Quaker beliefs, among them pacifism, meant that many were unable to serve in the armed forces during wartime.

Many volunteered to serve in warzones in the Friends Ambulance Unit (FAU).

Leslie Steed, 94, from Birmingham, who served with the FAU during World War II, said: “I would rather have been killed than kill somebody.”

Personal flying machines will be a reality, home computer and electric car pioneer Sir Clive Sinclair has said.

He told BBC Radio 4’s iPM programme that soon it would be “economically and technically possible” to create flying cars for individuals.

Sir Clive is best-known for the Spectrum computer and his failed electric car effort, the C5.

“I’m sure it will happen and I am sure it will change the world dramatically,” he predicted.

Despite his pioneering work in the field of computers, Sir Clive told BBC Radio 4 he was not an internet user.

“I don’t use it myself directly,” he said, explaining that as an inventor he tried to avoid “mechanical and technical things around me so they don’t blur the mind”.

TIL that more than 1 in every 365 people die on their birthday, and nobody’s sure why

A study by Swiss researchers has generated a startling statistic – you are 14% more likely to die on your birthday than on any other day of the year. But why should that be?

As the researchers put it, “birthdays… appear to end up in a lethal way more frequently than expected .”

This is not a joke. The study was carried out by legitimate scientists who analysed data from 2.5 million deaths in Switzerland between 1969 and 2008.

There are a number of hypotheses which may explain the finding.

Perhaps some people close to death “hang on” until their birthday, to reach another milestone? Or perhaps a significant number of people take greater risks on their birthdays, like driving home from their own parties drunk?

But Professor David Spiegelhalter, a statistician from Cambridge University, says the Swiss data does not support the “hanging on” theory.

“They don’t find any dip before so there’s no holding on,” he says, “and they don’t find any blip after, so there’s no jumping the gun. It’s purely a birthday effect.”

The Swiss data, he says, suggests “something on your birthday kills you”.
