The Spectator

There was much mirth in the West this week when Vladimir Putin’s Victory Day parade through Red Square included just one tank, itself a relic from a museum. The inference was that Russia has lost so much military kit in Ukraine that it is a shadow of the military superpower the Soviet Union used to be. Russia has certainly borne heavy losses (although any country conducting a foreign war would presumably have its military hardware on active duty rather than on ceremonial parade). But we should avoid being smug. The truth is that the war is not going well for the West either – at least in one respect. When Putin sent tanks into Ukraine on 24 February last year, western countries rapidly adopted a two-pronged strategy.

Machine learning Who came up with the phrase ‘artificial intelligence’? – The term was coined by US computer scientist John McCarthy in 1955, arising from a summer school held at Dartmouth College in New Hampshire. The blurb for the project declared: ‘the study is to proceed on the basis of the conjecture that every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.’ However, McCarthy seems to have had a slightly loose concept of what constitutes AI. He once had a debate with a colleague in which he asserted that even a thermostat could be said to have ‘belief’ on the grounds that it believed a room should be set at a particular temperature.

Irreligious tolerance Sir: Your editorial ‘Crowning glory’ (6 May) celebrated the religious tolerance in Britain that will permit a multifaith coronation. However, it didn’t acknowledge that in modern Britain nearly half of people have no religious belief. This acts as a buffer, making religious differences of opinion of less importance. Britain is one of the least religious countries in the world. In more strongly religious countries, such tolerance is harder to find. Michael Gorman Guildford, Surrey Admirals on horseback Sir: If Admiral Sir Tony Radakin only had to march at the coronation (Admiral’s notebook, 6 May), he was fortunate. At the 1953 coronation, Lt Cdr Henry Leach (later Admiral of the Fleet Sir Henry Leach) was in charge of the naval element.

Home Scotland sent the Stone of Scone to Westminster for the coronation of King Charles and Queen Camilla at Westminster Abbey. The ceremony included the recognition of the King, his oath to maintain the ‘Protestant Reformed Religion established by law’, his anointing (with oil free from civet oil or ambergris from whales), investiture with orb and sceptres and his crowning, enthronement and reception of homage. The Queen was also to be anointed and crowned. The ceremony was set within a Church of England service of Holy Communion. The Prime Minister, Rishi Sunak, accepted an invitation to read the Epistle. Jews, Sunni and Shia Muslims, Sikhs, Buddhists, Hindus, Jains, Bahais and Zoroastrians were invited. The Duke of Sussex popped over for the event, but the Duchess did not.

Uneasy lies the head In a 2018 BBC documentary Elizabeth II commented on the weight of the crown at her coronation, complaining that if you wore it for too long ‘your neck would break off’. What will be the burden on Charles III’s head? – At the moment of the coronation Charles will wear St Edward’s Crown, made for Charles II in 1661. That weighs 2.07kg. Prior to 1911 it weighed 2.6kg – although both Victoria and Edward VII were spared having to wear it. – However, for his departure from Westminster Abbey that crown will be removed and he will wear the Imperial State Crown instead, which weighs 1.06kg.  – By contrast, most full-face motorcycle helmets (just about the heaviest thing people wear on their heads in day-to-day life) weigh between 1.
