You may be as fascinated to learn that there are about 80 species of Surgeonfish. One of the most popular is the electric-blue variety represented by the optimistic, caring and sociable ‘Dory’ in the hit-movie Finding Nemo!

This striking fish is known by a bewildering variety of names. A few include Blue Tang, Regal Tang, Hippo Tang, Wedge-Tail Blue Tang, Palette Surgeonfish and Flagtail Surgeonfish. To avoid the confusion, scientists know it as Paracanthurus hepatus.

We were curious about how scientific names for plants and animals are devised. It didn’t take long to pick up the trail of Swedish naturalist Carl Linnaeus, whose story (luckily for us) comes complete with an Australian twist!

Back in the 17th and early 18th centuries, plants were given long Latin phrases for names that reflected their particular botanical features. As more plants were identified, names became longer and longer, and more and more difficult to remember and use.

Carl Linnaeus

Linnaeus, who was born in 1707, was to change all that. In 1735 he introduced a method of naming plants that he later applied to animals. It brought simplicity and consistency to a befuddling array of previous systems, classifying each organism according to its physical attributes.

In the words of the Linnean Society of London, he gave “a one-word name such as Rhododendron or Equus to a genus and a two-word name such as Rhododendron ponticum or Equus caballus to an individual species within the genus.”

Known as ‘binomial nomenclature’, it answered the dire need for a standardised approach. No wonder it was applauded and universally accepted, and still provides the basis for naming organisms to this day.

During his work to catalogue all known living things, Linnaeus appointed students to undertake botanical and zoological expeditions throughout the world. Known as his ‘apostles’, they included a Daniel Solander, the first university educated scientist to set foot on Australian soil.

Linnaeus had advised Solander to go to England where, luck would have it, he met Joseph Banks. In 1768, the influential naturalists invited Solander to join the scientific staff of Cook’s Endeavour expedition to the Pacific.

As we know, after visiting Tahiti and sailing around New Zealand, Cook sighted the east coast of Australia, tracking it northwards to Botany Bay where the two scientists began collecting Australian plant specimens for description using the Linnaean method of classification.

Subsequently, the ship sailed into the tropical waters of the Great Barrier Reef, and area teeming with beautiful blue Paracanthurus hepatus.

Two British students have had the honour of designing the official UK coins to celebrate the London 2012 Olympic and Paralympic Games.

Architectural student Saiman Miah from Birmingham, and graphic and media design graduate Pippa Sanderson from Worcestershire, created the two £5 coins as mementos of London 2012.

The winning designs were selected following a Royal Mint competition for art and design students in higher education. Students were challenged to create a design celebrating the capital’s role as host city of London 2012. Designs were requested that could be symbolic or literal and could involve the use of emblems or lettering.

Saiman said the inspiration for his design came from his love of architecture and it includes a detailed impression of London’s iconic skyline. “I wanted a classical design that represented old traditional British values,” he said. Saiman also incorporated pictograms of athletes around the edge of the skyline to create a clock face referencing another London icon, Big Ben.

Pippa took inspiration from the Games themselves. “My design idea came from the concept of rings and what they mean, from the track at the Olympic Stadium to the Olympic rings.” Split into these four sections, her design features a spoked wheel for manoeuvrability, a target for accuracy and a stopwatch for speed and includes the face of Big Ben to represent London.

The Royal Mint said Olympic coins can be traced back to 480BC.

A £50 banknote featuring Matthew Boulton and James Watt, pioneers of the Industrial Revolution, entered into UK circulation last week. We thought we’d draw that to your attention because one half of the famous partnership has a fascinating connection with early Australian coinage.

Portrait of Matthew Boulton

The son of a Birmingham metal product manufacturer, Matthew Boulton built the groundbreaking steam-powered Soho Mint in 1788. As well as medals and tokens, he produced high-quality coins from copper and silver for which he has been described as the founder of modern coinage

Boulton made the famous cartwheel penny at his Soho Mint, a coin which was exported to the colonies – including cash-strapped New South Wales. “Near four tons” of 1797-dated pennies arrived aboard the Porpoise, which docked in Port Jackson in 1800.

Each copper coin weighed 1oz. Designed to prevent wear, they were known as ‘cartwheels’ because of their large size. A bust of George III appeared on the obverse and on the reverse was seen a seated Britannia with shield holding olive branch and trident.

At this time, an assorted rag-bag of coins from around the globe passed for currency in Sydney Town. Unfortunately, relative values for each coin were often disputed.

With the arrival of the cartwheel pennies, Governor King took the opportunity to settle values “for all the specie legally circulating in this colony” by way of a Currency Proclamation.

King regarded the cartwheel penny as vital to “dealings of the ordinary customers of the business houses” and in a bid to prevent supplies being syphoned off by visiting traders, he decreed that it should circulate at 2d – twice its face value! By inflating coin values locally, he believed, visiting merchants would be reluctant to accept them.

The 1797 cartwheel copper penny is significant in being one of the very first coins made using Matthew Boulton’s steam-powered coining press. As the trigger behind King’s famous Proclamation, it occupies an important place in Australian numismatic history. Moreover, as the first coin formally exported to New South Wales, it can also be regarded as Australia’s first official coin.
