Walton sculpture unveiled - 'Apples and Atoms'

A sculpture celebrating the life and work of  Ernest  T.S. Walton, Nobel Laureate for Physics, and former  graduate  and professor at Trinity College Dublin, was opened to the public by Minister for Education and Skills, Ruairí Quinn TD, this week at  a special ceremony at TCD. The sculpture titled ‘Apples and Atoms’   was designed by artist, Eilís O’Connell RHA.

Ernest T. S. Walton studied at Trinity where he was a scholar and won many College prizes, including a gold medal in experimental science. He graduated with joint honours in mathematics and physics in 1926 and went to Cambridge to do his postgraduate work. Thus began the momentous collaboration between Walton and his fellow physicist, John Cockcroft, which exploited linear acceleration methods to induce nuclear disintegration by artificial means, as observed by Ernest Walton, on April 14^th, 1932. It was the first time that Einstein’s E=mc²was verified directly in a nuclear reaction. His and Cockcroft’s success, using artificially accelerated particles for experimenting on the atom, meant the research into the nature and structure of the atom was no longer restricted by having to rely on natural sources of radiation. In 1946, Walton returned to Trinity College, to become the Erasmus Smith Professor of Natural and Experimental Philosophy where he remained until 1985.

“Ireland is home to many science heroes and Ernest T.S. Walton is one of our leading ones. This sculpture pays homage to him as a scientist, teacher and truly celebrates his scientific legacy  that continues to educate and inspire our students of science today, ” said Minister for Education and Skills, Ruairí Quinn.

Commemorating the 80^th anniversary of the experiment, Trinity invited six artists to submit a design, honouring Ernest T.S. Walton’s research achievements as well as 30 years of dedication to science education. Eilís O’Connell’s design was selected by a panel that included representatives from the Walton family, the School of Physics, the College Art Collections, students and external visual arts professionals.

“The sculpture was commissioned to commemorate Ernest T.S. Walton as a significant figure in the history of the College and in the development of science globally.  It reinforces Trinity’s special connection with him and is an opportunity to honour him as a scientist as well as a champion of science education, an academic and an Irishman,” said Provost of Trinity, Dr Patrick Prendergast.

The sculpture by  Eilis O’Connell is a stack of mirror polished spheres, increasing in size as they rise upward which appear to defy gravity. It is located beside the Fitzgerald Building, home to the School of Physics. Reflected in the stack of spheres are specially planted native Irish apple trees that refer to the private man and his keen interest for growing fruit trees.

“The sculpture pays homage to Walton’s most important characteristics - his intellectual rigour and hands-on ability to physically build the particle accelerator and his nurturing ability as teacher and father.  A man is not defined solely by his academic achievements but also by the memories he leaves behind in others,” explained sculptor, Eilís O’Connell.

Ernest T.S. Walton generously presented his papers to the College Library in 1993; his family subsequently donated his Nobel medal. A small exhibition, which includes the medal, is currently on display in the Long Room, to mark the formal launch of the sculpture.

The commission was made possible by the support of the Walton family, the Provost, the School of Physics, the Trinity College Dublin Association and Trust, the Department of Education and Skills, the Institute of Physics in Ireland, the Fellows and alumni of Trinity and the Science Gallery.

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

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.

Coming Soon: Walton Magazine - Winter Edition

New Irish Science Magazine Launched

"Scientists love their subject matter more than Cork people love Cork. No other professionals give up their spare time to help promote their profession in the same way scientists do." So says John O'Donoghue. And he should know - having just led a team that launched a new science and technology magazine.

Named in honour of Ernest Walton, physicist and Ireland's only scientific Nobel Prize winner, Walton Magazine comes from a group of young Irish scientists. It's published online and in print every quarter.

The first edition, available to read online for free, covers such diverse areas as a history of Walton himself, space travel, online privacy, Project Maths and the Science 140 project.

You can also read yours truly on recent advances in the science of the potato. You have been warned!

We can't have enough avenues for promoting and reading about science and an endeavor like this deserves to be supported. I wish the Walton team all the best.
