The so-called Suess effect in radiocarbon (14C) has been known for decades. Geological sources of carbon like coal and oil, that formed many millions of years ago, long since lost their radiocarbon through radioactive decay – they contain 14C-free “dead” carbon. From the mid-19th century the radiocarbon activity of the atmosphere declined as dead carbon from fossil fuels was dug out of the ground and burnt producing carbon dioxide (CO2) in the atmosphere.
For all its supposed isolation out there beyond the pale of acceptable discourse — marginal words in the mouths of marginal people — we know a good deal about slang. We know its lexis, and keep chasing down the new arrivals; we know its lexicographers, some very well; we know its speakers, and note that far from monosyllabic illiterates, they coin some of the most inventive usages currently on offer.
So, what is crystallography? Put simply, it is the study of crystals. Now, let’s be careful here. I am not talking about all those silly websites advertising ways in which crystals act as magical healing agents, with their chakras, auras and energy levels. No, this is a serious scientific subject, with around 26 or so Nobel prizes to its credit. And yet, despite this, it remains a largely hidden subject, at least in the public mind.
Stephen Smith, author of Environmental Economics: A Very Short Introduction, gives us an insight into what environmental economists do, what environmental economics is about, and how it measures and influences our impact on the environment. He also explores the steps we need to take to protect it at an international level.
We are currently living through a period when “antisemitism” seems to be on the rise in Europe, and is now a hot topic of debate in Britain, because of a few clumsy statements by some prominent Labour politicians (along with a very few statements that do appear to have an actual antisemitic animus).
In February, when the local ewes were heavy with their lambs, the newspapers carried an article about a Japanese company called Spread, based in Kyoto. In a fully-automated operation covering just over an acre the company plans to be producing 30,000 heads of lettuce per day by 2017, and more than ten times that number within five years. The company’s website calls it a ‘vegetable factory’.
American basketball star, Darsh Singh, a turbaned, bearded Sikh, featured this April in a Guardian Weekend piece on cyberbullying. He recalled how his online picture had been circulated with Islamophobic captions. Long before that he’d had to get used to people yelling things like “towelhead”. Since 9/11, Sikhs haven’t just been verbally insulted but have suffered ‘reprisal attacks’.
This year marks the one hundredth anniversary of the Easter Rising, a violent attempt by Irish republicans to end British rule in Ireland. Though a momentous event in itself, the Rising should be understood in the context of a decade of revolutionary activity during which Irish political culture was profoundly radicalised and partition came to look inevitable. It must also be understood in the context of the First World War.
A couple of years ago, I wrote about the consequences of David Cameron’s Bloomberg speech, where he set out his plans for a referendum on British membership of the EU. I was rather dubious about such a vote even happening, and even more so about the quality of the debate that would ensue. As much as I was wrong about the former, the latter has been more than borne out by events so far.
Many playwrights have explored race relations, particularly in America. The growth of the Civil Rights Movement gave rise to a range of plays protesting racism and exploring the African-American experience. Lorraine Hansberry made history as the first black woman to have a play on Broadway: A Raisin in the Sun, also the first play on Broadway to be directed by a black director.
Ancient Egyptian art dates all the way back to 3000BC and provides us with an understanding of ancient Egyptian socioeconomic structures and belief systems. The Ancient Egyptians also developed an array of diverse architectural structures and monuments, from temples to the pyramids that are still a major tourist attraction today. But how much do you know about Ancient Egyptian art and architecture?
It was only after I finished writing The Founding Fathers: A Very Short Introduction that I got to see the off-Broadway version of Lin-Manuel Miranda’s “Hamilton: An American Musical” at New York City’s Public Theater. I was lucky enough to see the Broadway version (revised and expanded) last month.
Proving to be both varied and fascinating, moons are far more common than planets in our Solar System. Our own Moon has had a profound influence on Earth, not only through tidal effects, but even on the behaviour of some marine animals. But how much do we really know about moons?
Pre-eminent among writers of mystery stories is, in my opinion, Dorothy L. Sayers. She is ingenious, witty, original – and scientific too, including themes like the fourth dimension, electroplating, and the acoustics of bells in some of her best stories. She is also the inventor of the voice-activated lock, which her hero Lord Wimsey deploys in the 1928 short story ‘The Adventurous Exploit of the Cave of Ali Baba’.
In Rome on 22 June 1633 an elderly man was found guilty by the Catholic Inquisition of rendering himself “vehemently suspected of heresy, namely, of having held and believed a doctrine which is false and contrary to the divine and Holy Scripture”. The doctrine in question was that “the sun is the centre of the world and does not move from east to west, that the earth moves and is not the centre of the world.
Some individuals loom larger in mycological history than they deserve, but, to be fair, this mild indictment applies both to those with, and those without, a Y chromosome. The science of mycology blossomed in Darwin’s time, when German botanist Anton de Bary (1831-1888) began to decode the life cycles of fungi and penned the first textbook on fungi.
