"She looks beneath the shadow of my wings"

This plaque in Skibbereen, in West Cork marks the birthplace of the sisters Ellen and Agnes Clerke, both noted writers, particularly on the science of astronomy.

Living together in Skibbereen, Italy and London for most of their lives, the women pursued a common interest in science and, in particular, in the communication and popularisation of the subject.

Ellen was born on 20th of September 1840 in Skibbereen and Agnes was born on February 10th 1842. Their father was a bank manager in the town and a Protestant. Their mother was Catherine Deasy, a Catholic.

Although the family moved to Dublin in 1861 and to Queenstown (Cobh) in 1863, the sisters spent much of their childhood in West Cork. Due to their father's wealth and stature, the family was able to spend the cold winters in Rome (1867 and 68); Naples (1871 and 1872); Florence (1873-76). The sisters made the most of these trips abroad - spending many days reading in the Florence Public Library.

The sisters only brother Aubrey noted the defining influence of their father, John William Clerke, on the scientific aptitude of the sisters:

"Although a classical scholar of Trinity College, Dublin", wrote Aubrey Clerke in 1907,"his interests were for the most part scientific".

"In our earliest years his recreation was chemistry, the consequential odours of which used to excite the wrath of our Irish servants. Later a 'big telescope' (4 inch aperture)was mounted in the garden, and we children were occasionally treated to a glimpse of Saturn's rings or Jupiter's satellites".

"These trivial things show that it was in an environment of scientific suggestion that our early lives were passed", wrote Aubrey Clerke in a foreword to a booklet recalling his sisters' lives.

The Clerke family home in Skibbereen

The family moved to London in 1877 and Agnes published the A Popular History of Astronomy during the Nineteenth Century in 1885. Her second book The System of the Stars was published in 1890.

Agnes Clerke was not a practicing astronomer and her contribution to the field is largely based on her tireless collation and interpretation of data from other researchers and the communication of that research. She could, perhaps, be best described as a science communicator, using today's vernacular.

Despite not working as an astronomer herself, she had, of necessity a vast knowledge of the area and spent a three month period in 1888 at the Cape Observatory (Cape Town) updating her knowledge.

Agnes Clerke was a recipient, in 1893, of the Actonian Prize from the Royal Institution in London. This award was presented to the person who "in the judgement of the committee of managers for the time being of the Institution, should have been the author of the best essay illustrative of the wisdom and beneficence of the Almighty, in such department of science as the committee of managers should, in their discretion, have selected".

A member of the British Astronomical Association, Agnes was also an honorary member of the Royal Astronomical Society.

Ellen Clerke is also known for some astronomical writings including the pamphlets "Jupiter and His System" and "The Planet Venus" but she was also known as a journalist, poet, novelist and commentator on religious issues, with a keen interest in Italian matters having lived in the country for several years.

Ellen's poem Night's Soliloquy, beautifully captures her and her sister's love of astronomy.

Agnes has the distinction of having a crater on the surface of the moon named in her honour. Crater Clerke is about 6 km in diameter and located very close to the Apollo 17 landing site - the last landing of humans on the lunar surface.

Ellen died after a short illness on March 2nd 1906. Huggins notes that "these sisters were lovely and pleasant in their lives and in death they were but little divided". Agnes died on January 20th 1907 from complications associated with pneumonia.

NIGHT'S SOLILOQUY

(1881)

by Ellen Mary Clerke

Who calls me dark ? for do I not display
Wonders that else man's eye would never
see?
Waste in the blank and blinding glare of Day,
The heavens bud forth their glories but to me.

Is it not mine to pile their crystal cup,
Drain'd by the thirsty sun and void by day.
Brimful of living gems, profuse heap'd up.
The bounteous largesse of my royal way ?

Mine to call o'er at dusk the roll of heav'n.
Array its glittering files in order due ?
To beckon forth the lurking star of Even,
And bid the constellations start to view ?

The wandering planets to their paths recall.
And summon to the muster tenant spheres.
Till thronging to my standard one and all,
They crowd the zenith in unfathom'd tiers ?

Do I not lure stray sunbeams from the day.
To hurl them broadcast as wing'd meteors
forth ?
Strew sheaves of fiery arrows on my way.
And blazon my dark spaces in the north ?

Is not a crown of lightnings mine to wear.
When polar flames suffuse my skies with
splendour ?
And mine the homage with the sun to share.
His vagrant vassals rush through space to
render ?

Who calls me secret ? are not hidden things.
Reveal'd to science when with piercing sight
She looks beneath the shadow of my wings.
To fathom space and sound the infinite ?

In plasmic light do I not bid her trace
Germs from creation's dawn maturing slow ?
And in each filmy chaos drown'd in space
See suns and systems yet in embryo ?

Science Communication enters the Dragon's Den

New Irish #SciComm venture Walton Magazine hits the airwaves tonight when they pitch their wares on Dragon's Den.


Magazine editor John O'Donoghue and PR Manager Ger O'Donovan braved the den to get funding for their fledgling science communication magazine.

The magazine was launched in the Autumn of 2012 and deals with STEM issues from an Irish perspective. My own articles for Walton have dealt with current research on the potato as well as the future of food production and the importance of plant pathology.

You can see Walton Magazine take on the Dragons tonight (Easter Sunday, 31st March) at 9.30pm on RTE One television and join in the conversation on twitter @waltonmagazine using the hashtag  #ddirl

Private funds could help secure scientific heritage

Some positive steps forward could be on the way for number 5 Grenville Place in Cork City, the former home of mathematician George Boole.

The building partially collapsed in October 2010 and has been languishing in a terrible condition since, despite pressure being applied to Cork City Council and others to protect the building as part of Cork's cultural, historic and scientific heritage.

George Boole was the first Professor of Mathematics at Queen's College Cork (now University College Cork) and is widely regarded as the 'father' of computer science and certainly of Boolean algebra. Boole lived at Grenville Place from 1849 to 1855 and it is where he wrote one of his most important works: An Investigation of the Laws of Thought, on Which are Founded the Mathematical Theories of Logic and Probabilities.

In March of 2011, Cork City Manager Tim Lucey said that, subject to the consent of the owner, the City Council would "establish the level of interest in its future use/development, from the range of bodies which have expressed views to the Council on its historic importance".

At a Cork City Council meeting earlier this month, Mr. Lucey told councillors that a Building Condition and Feasibility Study had been completed for No. 5 Grenville Plane and had been circulated to University College Cork.

"It has been suggested to UCC that a small working group be established to determine how best to resolve issues and see what possibilities exist to deal with this important building in light of upcoming anniversaries of George Boole in 2014/2015", said Mr. Lucey.

The 150th anniversary of Boole's death falls on 8th December 2014. The 200th anniversary of his birth takes place on 2 November 2015.

The City Manager also confirmed that "preliminary discussions" had taken place between the university where Boole was professor of mathematics and the city council. According to the Irish Examiner, this working group will consider approaching Apple Computers, which has its European headquarters in Cork and other computer and software firms to see if private funding would be available to help preserve this building and Boole's memory in the city.

Are you interested in the greatest challenge on Earth?

The Director of the National Botanic Gardens, Matthew Jebb, has said that the study of plants has never been more important given the global problems we face - the greatest challenge on Earth.

"By 2050, the UN estimates the world will need 70% more food, 55% more clean water and 60% more energy than today", said Jebb. "These challenges will have to be met through the sustainable use of natural resources. The most important question facing the human race must be how will the world feed our children’s children? The answer is with advances in plant biology and ecology, and using this knowledge in field-based solutions".

A career and information day for Botany and Plant Science will take place at the National Botanic Gardens in Dublin later this month.

The event, on Thursday 21st March from 2pm-5pm, is the perfect opportunity for those interested in a university degree, or career in plant sciences, to learn more.

Matthew Jebb said the event was "an unparalleled opportunity to hear first hand from botanists engaged in biodiversity, ecology, conservation and genetics jobs, and the potential prospects in one of the most important future careers for saving our planet".

Writing in advance of the information day, Jebb said that plant science had never been more important: "The growing and increasingly prosperous human population needs abundant safe and nutritious food, shelter, clothes, fibre, and renewable energy, and needs to address the problems generated by climate change, while preserving habitats. The key to solving these challenges is Plant Science; plants are the source of all the food we eat and the air we breathe".

Plant scientists, researchers and teaching staff from the Botanic Gardens and from University College Cork, University College Dublin, Trinity College, NUI Maynooth and NUI Galway will present on the day and provide information on the courses they offer.

The Botany and Plant Science Career and Information Day takes place at the National Botanic Gardens, Glasnevin Dublin on Thursday 21st March from 2pm-5pm. More details can be found on the Gardens website.

Naming of names

I love these - Famous scientists' names presented in a way that represents their most famous achievement. Designed by Kapil Bhagat of India, I spotted them on broadsheet.ie

Water, water, everywhere...

It takes over 17,000 litres of water to produce just 1 kg of chocolate.

That's one of the startling figures compiled in a new report on food waste by the Institution of Mechanical Engineers in the UK.

The report: Global Food - Waste Not, Want Not; made the news last month because of the headline-grabbing figure of 50%. That's the proportion of food wasted worldwide without ever reaching a human stomach.

The figures for water usage in the report come from the Water Footprint Network and make for stark reading when tabulated (see below). For example, it takes 822 litres of water to produce 1 kg of apples.

On average, 1 kg of beef takes 15,415 litres of water to produce and one cup of tea takes 27 litres.

The various wasted inputs (water, energy, agrochemicals, etc.) associated with wasted food is often not considered by consumers but, as the report states: "[the 50% headline figure] does not reflect the fact that large amounts of land, energy, fertilisers and water have also been lost in the production of foodstuffs which simply end up as waste".

Water use in agriculture (Source: Global Food - Waste Not, Want Not)

According to a recent European Environment Agency (EEA) report on water use in Europe, agriculture accounts for 33% of total water use. That figure can go as far as 80% in parts of southern Europe where irrigation of crops is essential and accounts for almost all agricultural water use.

In the clamour for higher yielding varieties of crop plants for agriculture, it makes sense to stop and think about how current yields are squandered and how limiting resources such as water and energy and thrown in the bin.
