In Rapid Fire, veteran broadcaster JOHN MAYTHAM has collected questions submitted by 567 CapeTalk listeners to test his remarkable general knowledge in the ever popular insert of the same name on his afternoon drive-time show. Here are a few of some the oddest, arcane and most surprising questions – and answers.
Are there animals that can live without water?
The North American kangaroo rat is most often cited in internet discussions of this topic. These rats do need water to survive, but they have evolved such that it is possible for them to go through their entire life cycle, between three and five years, without ever drinking water. They collect seeds during moist conditions, and live off the nutrition and moisture stored in those seeds.
Then there is an extraordinary water-wise amphibian, the Australian water-holding frog. It stores water in pockets of skin all over its body, but holds most of it in the bladder. It is able to store double its body weight in water, and can live for up to five years without needing to take a drink. Local Aboriginals, if they’re thirsty while out in the bush, will try to catch one of these frogs and squeeze the water directly from the frog’s bladder into their mouths.
Why are weddings rings traditionally worn on the fourth finger of the left hand in many Western cultures?
This is based on a traditional (but incorrect) belief that there is a vein that runs directly from that finger to the heart. It was called the vena amoris, the “vein of love”.
What is the link between the musical works of Handel and Bach, and the one-rand coin?
The words Soli Deo Gloria (To God alone the glory) appear on the one-rand coin. Those same words are also part of the dedication of many works by the likes of Bach and Handel.
Can a vegan eat a fig?
Hmmm, lots of nuance in the answer! It depends – on the fig and on the vegan. Some figs, like the Smyrna, are pollinated in such a way that the female wasp dies inside the fig. The body will be dissolved by acid activity, but strictly speaking,
there will be animal matter inside the fig. Some very strict vegans might see that as reason to avoid the fruit. Forgive me for being technical, but some fig species are parthenocarpic, which means they develop fruit-like structures that don’t require pollination. (Don’t worry, I don’t understand it either.) All vegans can eat these varieties with a clear conscience.
Bananas, on the other hand, are a different story. If they come from a field that has been sprayed with a pesticide like chitosan, then very strict vegans will look the other way because shrimp and crab shells are on chitosan’s list of ingredients. Did someone mention slippery slopes?
The first British astronomer at the Cape, Fearon Fallows, is buried in the grounds of the South African Astronomical Observatory in a suburb of Cape Town. His grave has one very unusual feature. What is it?
The grave is twelve feet deep. Fallows knew he was dying and, fearing that his burial site would be disturbed by grave robbers, he asked to be buried twelve feet down. As the observatory is on rocky ground, the digging must have been very hard work!
What was bought in the first-ever bitcoin purchase?
Don’t ask me to explain bitcoin – it’s dark matter as far as I’m concerned. All I can do is report the fact that on 22 May 2010, Laszlo Hanyecz made the first real-world bitcoin transaction by buying two pizzas in Jacksonville, Florida, for 10 000 BTC. And the fact that, had he made himself a sandwich instead and held onto those bitcoin (bitcoins?), then at the time of writing this book those 10 000 BTC were worth $11 million. (I hope those pizzas were really good.) [Ed’s note: today those pizzas are now worth more than $105 million.]
Advertisements for watches usually feature a watch face set at a particular time. What is that time and why has it been chosen?
The time is ten past ten, because this position of the watch hands is seen as the best possible framing of the manufacturer’s logo and also creates the happy impression of a smiling face.
Why did George Dawson rise to fame in the US?
He learnt to read at the age of 98. Still described as ‘America’s poster child for literacy’, Dawson had a rough life, being the grandchild of slaves and first put to work at the age of four. He died at the age of 103, but enjoyed national attention in the five years between learning to read and passing away. Two universities conferred honorary degrees on him; television programmes were made about him; he appeared on Oprah, where he said, “It’s never too late to learn, I’m still learning now”; he had a school named after him; and he co-authored a biographical work, Life Is So Good, when he was 102.
