If a social conversation turns to the history of navigation – a turn that is not so unusual as once it was – the most likely episode to be mentioned is the search for a longitude method in the 18th century and the story of John Harrison. The extraordinary success of the book by Dava Sobel has popularised a view of Harrison as a doughty and virtuous fighter, unfairly disadvantaged by the scientific establishment.
We now know that the Earth is many billions of years old, and that it has changed an unimaginably number of times over millennia. But before the mid-eighteenth century we believed that the Earth was only a few thousand years old. Then scientists (who we now call geologists) began to explore the Earth’s layers and found fossils, suggesting it was much, much older than they first thought.
As we mark Voltaire’s 323rd birthday – though the date of 20 February is problematic, the subject of another blog – what significance does the great Enlightenment writer have for us now? If I had to be very very short, I’d say that Voltaire lives on as a master of the one-liner. He presents us with a paradox. Voltaire wrote a huge amount – the definitive edition of his Complete works will soon be finished, in around 200 volumes.
From tornadoes and typhoons to deciding the best day for a picnic, the weather impacts our lives on a daily basis. Despite new techniques and technologies that allow us to forecast the weather with increasing accuracy, most of us do not realise the vast global movements and forces which result in their day-to-day weather. Storm Dunlop tells us ten things we should know about weather in its most dramatic and ordinary forms.
The accelerated ageing of the populations of developed countries is being matched in the developing world. In fact, in 2017, for the first time in history, the number of persons aged 65 and over will outstrip those aged 5 and under. This population trend is not just a temporary blip, not just due to a short-term outcome of the baby boomer generation.
of the extraordinary things about our modern world is just how closely we are brought into contact with rock in everyday life. Now this might seem a little counter-intuitive. As I child, I grew up with cartoons such as The Flintstones and, a little later, sat goggle-eyed through films such as One Million Years BC. There the Stone Age protagonists acted out derring-do amid caves, craggy landscapes and erupting volcanoes.
AIDS is a fast moving epidemic and some of the data and assertions were immediately out of date. For example, the book failed to foresee the massive expansion in treatment. In 2008, there were 28.9 million people living with HIV, and a mere 770 000 were receiving anti-retroviral drugs. By 2015, there were 36.7 million people infected with HIV, but 17 million were on treatment.
As Britain and her empire swelled in size and confidence, Dickens’s own belief in it diminished. For him the best of times were becoming the worst of times, Victorian high noon was dusk verging on midnight.
When Sir Ivan Rogers stepped down in January as the UK’s top official in Brussels, he urged his colleagues to ‘continue to challenge ill-founded arguments and muddled thinking’ and not to be afraid ‘to speak the truth to those in power.’ The implication was clear. The government’s Brexit preparations displayed all these failings but the politicians responsible did not like having this pointed out.
On his recent visit to England Barack Obama chose to tour Shakespeare’s Globe, on Bankside; and in the last days of his Presidency, interviewed about his reading habits, he spoke touchingly and revealingly of his admiration for Shakespeare’s tragedies, and of what they had taught him. ‘I took this wonderful Shakespeare class in college’, he said, ‘where I just started to read the tragedies and dig into them.
In September 2015, the UK Met Office and Met Éireann (the Irish meteorological service) announced a project to give names to potentially damaging storms. The basis for naming any particular storm was the expectation that there would be major impacts on conditions over the British Isles and, in particular, of very high winds. The first storm, Abigail, brought high winds to northern Scotland and the Outer Hebrides.
Given our constitutional separation of powers, it seems odd that a presidential inauguration takes place on the Capitol steps. Like so much else in American history, the story begins with George Washington. In 1789, the First Congress met in New York City, where it proceeded to count the electoral ballots, an easy task since the vote had been unanimous.
Almost a decade after the global financial crisis, most regulators and commentators would agree that the banking industry is far more strongly capitalized than it was in the run-up to the crisis. Looking forward, there is less consensus as to how much capital banks should hold. Neel Kashkari, head of the Minneapolis Federal Reserve, attracted attention recently by calling for huge increases in minimum capital requirements for banks.
“Be it ever so humble, there’s no place like home.” “Home is where the heart is.” These well-known expressions indicate that home is somewhere that is both desirable and that exists in the mind’s eye as much as in a particular physical location. Across cultures and over the centuries people of varied means have made homes for themselves and those they care about.
There are two contrary ways of characterizing myth. By far the more common way is negative: a myth is a false or delusory belief or story. Here the aim is to expose the myth and be done with it. To take an innocuous example, the story that young George Washington was so honest that he could not deny to his father that he, the son, had chopped down the cherry tree is a myth because it never occurred.
The ancient Greek philosophers believed that the Sun, Moon, planets, and stars were mathematically perfect orbs, made from unearthly materials. These bodies were believed to move on perfectly symmetric celestial spheres, through which a backdrop of fixed stars could be seen, rotating majestically every 24 hours. At the centre was the motionless Earth. For the Greeks, the power of reason was more important than observation.
