Maths - It Is Rocket Science

Taking place in the Armagh Planetarium between August 22nd and 26th ‘Maths – It Is Rocket Science', a Department of Education & Skills approved course for primary school teachers from both the Republic of Ireland and Northern Ireland, will provide participants with specific techniques and insights in using the theme of Space as a key learning aid in the classroom. 

The course is being run by ESERO Ireland, the European Space Education Office working to inspire and engage students in science and technology subjects and in making Ireland’s burgeoning space industry more accessible to students and the public.

With research having shown that Space related matters can be used as key interest points for children in the teaching of maths, science and geography the course in the Armagh Planetarium is the perfect opportunity for teachers to increase their knowledge in this area.

Teachers interested in taking up a place on the course should note that ESERO Ireland is offering a limited number of bursaries, worth up to €250 in total, to cover the costs of travelling to the course from outside the normal commuter range. The bursaries are to be set aside to cover the cost of fuel and accommodation for the five day duration of the course.

The Armagh Planetarium is the ideal location for the course, dedicated in its work in astronomy education at all levels and providing an atmosphere conducive to the teaching of Space in the classroom in progressing with a number of different STEM subjects.

The focus of ‘Maths – It Is Rocket Science’ will be on enquiry based learning, beginning with a hands-on session based around the Discover Primary Science and Maths programme run by DSE.

Primary teachers who have taken part in the course over the past few years have spoken of how the Armagh Planetarium is an ideal venue for sparking ideas and debate – and on a more practical level of how the course has enabled them to put lesson plans with a Space influence into place which have received a great reaction in the classroom.

Places on the course are limited to 20.

A similar event takes place at Blackrock Castle Observatory, Cork on July 4th-8th. See here for more details.

The Potato and Walter Raleigh: Never let the facts spoil a good story

I've got a particular interest in potatoes. Lots of my research is based on dealing with potato pests, so I've got an affection for the tuber.

That's why I was so excited to see a new website, potato.ie launched to promote the Irish potato as 'Ireland's Feel-Good Food'. Take a look, it's full of recipe ideas, fun facts and information about Solanum tuberosum.

If I've got one complaint, it is that the website highlights the supposed connection between Sir Walter Raleigh and the potato. A connection which is just not supported by the facts.

Under the the 'History' section of the website, they note that "popular myth credits its introduction at Youghal, Co. Cork by Sir Walter Raleigh. Other anecdotal evidence suggest that the potato was washed up on the shores of Cork after the wreck of the Spanish Armada in the area".

To be fair to the Irish Potato Federation, they make it clear that they consider the Raleigh story an urban (or should that be rural?) myth and so it is.

The potato originated in South America and what is at question here is how it got to Europe and, in particular, how it got to Ireland and the UK.

The Walter Raleigh myth is a really nice story and in many ways, I'd really like it to be true, but academics and historians are pretty sure that it's not. The story 'dies hard' though due to is widespread publicity and legendary status.

The most likely theory for the introduction of potato to Ireland and Britain is that it arrived from Spain. The author William Coles wrote in London in 1657 about “the potatoes which we call Spanish because they were first brought up to us out of Spain, grew originally in the Indies…”

Even as far back as 1727, there was clearly a view that the potato came from Spain (and indeed there was people willing to reject that argument). The Anglo-Irish botanist Caleb Threlkeld wrote pompously:

“Those who would give to the Spaniards the honour of entrencing (sic) this useful root called the potato, give me leave to call designing parricides, who stirred up the mislead zeal of the people of this kingdom to cast off the English government which is the greatest mercy they ever enjoyed… To ascribe the honour of the English industry to the effeminate Spaniards cannot be passed over without remark… and if I might advise the inhabitants, they should every meal they eat of this root be thankful to the Creator for English navigation.”

"every meal they eat of this root be thankful to the Creator for English navigation"What a wonderful rant! But perhaps he protests too strongly? It's useful to note that nowhere does Threlkeld mention Raleigh to back up his assertions. Surely if the Raleigh myth was in play back in 1727, the author would have played it as his trump card? This suggests that Raleigh's name was introduced at a later date to support this argument.

The Spanish theory is also supported by Irish oral tradition.Seán O Neachtain wrote the poem Cáth Bearna Chroise Brighde (The Battle of the Gap of St. Bridget’s Cross) in 1750 and this clearly supports the Spanish theory.

The poem is a very lengthy account of a fictional battle, which takes place near Tallaght in Co. Dublin (the poem extends to 218 short verses).

In it, O'Neachtain refers to the potato as "An Spaineach Geal" - the kind-hearted Spaniard and refers to its supporters as "the friends of the Spaniards". At the beginning of the poem, the poet mourns the loss of "my dear Spaniard" saying his death will be "death for the gaels, woe to them all".

Clearly then there were cultural references to the Spanish Introduction in 18th Century Ireland. When exactly Raleigh's name became involved in the story is unclear. Brewer (1826) certainly links Raleigh to the introduction and says it happened in 1588 when Raleigh was Mayor of Youghal.

Whatever the truth, the Raleigh myth is an endearing one and there is little doubt that the southwest of Ireland is a location were potato cultivation was understood and practiced at an early stage, perhaps because of the mild climate. It is possible that Raleigh was used as a figurehead for those wanting to give the vegetable a more 'appropriate' or British image in light of its connections to Spain.

As a piece of fiction, the Raleigh myth is a great one, but we shouldn't confuse fact with fiction, even if it does spoil a good story.

Mutiny on the Bounty: A Botanical Experiment

The HMS Bounty visited Cork recently as part of a European Tour. The ship is a replica of the original Bounty and was constructed in 1960 for the MGM studios film Mutiny on the Bounty with Marlon Brando.

Update: On 29th October 2012, the Bounty sank off the North Carolina coast during Hurricane Sandy. News item.

The original Bounty was purchased by the British Admiralty as part of unique botanical experiment- to sail to Tahiti in 1787 and collect samples of breadfruit trees (Artocarpus altilis) and transport them to the West Indies where they could be transplanted and used in the British plantations as a cheap source of food for slaves.

William Bligh was chosen to captain the ship and Sir Joseph Banks of Kew sent one David Nelson to be the botanist on board the ship.

When they got to Tahiti, the crew collected 1,015 breadfruit plants and Bligh allowed some of the crew to remain on land for five months caring for the plants. This was a decision he would live to regret. Without the rigour of life onboard, some of the crew resented having to fall back under Bligh's command for the return journey.

Three weeks out of Tahiti, Fletcher Christian led a mutiny aboard the Bounty. Eighteen of the 44 men on board were set adrift along with the captain in the Bounty's launch. This included the botanist Nelson and his plants, which he had carefully tended, were also thrown overboard. The mutineers had apparently resented the fresh water rations being used to keep the plants alive.

The remaining mutineers took control of the ship and eventually settled on Pitcairn Island and burnt the ship in what is now Bounty Bay.

Bligh captained the small boat, without charts, the 3,600 nautical miles to safety at the Dutch port of Coupang in what is now Indonesia.

A few days after arriving, having survived the epic voyage, Nelson spent a day botanising in the mountains, caught a cold, and died.

Bligh noted in his log:
'The loss of this honest man I much lamented; he had with great care and diligence attended to the object for which he was sent. I was sorry I could get no tombstone to place over his remains.'

What started as a botanical experiment ended as one of the most famous ocean journeys ever recorded.


The Bounty has now left Cork and will reach Belfast in a few days to continue its European tour.

3QD Science Prize - Thank you!

Many thanks to those of you who voted for my recent post in the 3QD Annual Science Prize.

The post in question made the Semifinal based on the large number of votes it received.

However, the semifinalists needed to be whittled down to a group of six to make the final, to be judged by eminent theoretical physicist Prof. Lisa Randall, and my post was not one of those to make the cut.

Well, there is always next year!

Well done to the finalists, the winners will be announced on June 21st.
