The Neolithic stone circles at Avebury, roughly 23 miles from Stonehenge in Wiltshire, were among many hundreds of such circles in Britain. There are numerous theories as to how they were built and what they were used for, including the idea that they match certain features on Mars…

At Avebury there is a massive henge with a stone circle placed just inside its perimeter. This is Britain’s largest stone circle, having a diameter of over 1,000ft.. Inside that circle were two smaller circles but not much remains of these. At least one of the stones weighed over 100 tons.

It is thought that there were ninety-eight stones originally at Avebury. However, in the early 14th century and again in the late 17th/early 18th century, spates of religious zeal saw local people destroying them. One man was crushed to death under one of the stones as it fell and he was not able to be given a religious burial. It was this event which halted the first bout of destruction.

Inside the henge is the very picturesque 400-year-old Red Lion pub.

The Ministry of Defence (MoD) closed its telephone hotline for the reporting of UFO sightings in 2009. This was perhaps partly because they were finding it difficult to cope with the increasing numbers of mobile phone videos being submitted for analysis.

Today, UFO sightings (UAP is the modern acronym: Unidentified Aerial Phenomena) can be reported to organisations such as BUFORA ~ the British UFO Research Association. Of course, many people simply post their videos on social media and/or contact their local newspaper.

The MoD has released thousands of UFO sighting records in recent years. Most of these indicate that they were mistaken for man-made objects or weather phenomena. However, around 5% could not be explained away…

Sir Humphrey Davy (1778-1829) was an extremely talented chemist, poet and inventor. Born in Cornwall and employed in Bristol at the Pneumatic Institution, he first became known for his experiments with nitrous oxide, or ‘laughing gas’, by breathing it in himself. His friends tried it, too! Later, it would start to be used as an anaesthetic in dentistry.

Davy then moved to London in 1801 and succeeded in isolating the elements of sodium, potassium, magnesium, chlorine and iodine, among others, using the newly discovered process of electrolysis. He was also admired as a lecturer and was Professor of Chemistry from 1802 to 1812 at the Royal Institution. His presentation style was very popular as he was a charismatic speaker and used visual aids to great effect. His desire to communicate was also shown in his lifelong devotion to writing poetry, uncommon for a scientist.

In 1816, he invented a miner’s safety lamp which reduced the danger of explosions caused by naked flames in coal mines. This lamp is known as the ‘Davy lamp’.

Halley’s comet, officially called 1P/Halley, is named after Dr. Edmund Halley (1656-1742) from London, who was the first to calculate that it returned every 75 to 76 years. One of its famous appearances was in 1066, just before the invasion of Britain by William the Conqueror. He took it to be a sign of success and it was shown on the Bayeux Tapestry. The comet’s next appearance to the naked eye on Earth will be in 2061.

Dr. Halley published his theory in 1705 after analysing reports of observations in 1531, 1607 and 1682 and collating the similarities. Before that, people thought each sighting was of a different comet rather than the same one coming back. He would have had to live to the age of 101 to see the return of the comet he observed in 1682. Instead he died aged 85, having held the position of Astronomer Royal, the most prestigious accolade in astronomy, since 1720.

Halley’s theory has been supported by scientists’ use of high-powered telescopes and probes sent up to take samples around the comet during its last visit, in 1986.

Quoting Neil Oliver...

I love Britain more than anywhere else in the world. With all my heart I declare that those of us born here, or who have made a home here by choice, are the luckiest, most blessed of all people. I am British. I will always be British.
