Ashleigh is a Planetarium director in Donegal

Background

Ash McFadden was born in the US, in Kansas, but moved to the Rocky Mountains of Colorado at an early age. He attended primary school in Kansas, secondary in Colorado.

In 1965 he won the regional science fair aerospace award for an experiment to determine the effects of acceleration on mice, using rockets and a maze test he designed. He is credited with inventing the world’s first portable planetarium laser display system and holds the first licence granted by the US Bureau of Radiological Health to manufacture and sell laser display systems.

Degree

• Business (marketing, accounting) with physics, MacPherson College, Kansas, 1969.

He began a business degree as preparation for taking over the family jewellery business. This included a spell in Switzerland, studying watchmaking. His interests led him to take a range of other courses, including aeronautical engineering at Kansas State University, human anatomy and genetics.

Career snapshot

After college, he spent several “financially-successful but emotionally unfulfilling” years as a jeweller, gemologist, watchmaker, goldsmith and diamond-setter. During this time he continued his science education through reading, and found time to design and fly rockets and qualify for a commercial pilot’s licence, which he still holds.

His studies of micromechanics (watchmaking), optics (gemology) and electronics (building his own synthesizers) led to an interest in the then-new technology of laser applications. Eventually, he “saw the light” and left the entire jewelry business to found Laser Systems Development Corporation.

He financed the start-up through playing keyboards as a road musician for a dozen or so rock bands, flying freight around America in World War II surplus C-45s and performing in air shows.

He developed a laser display system that someone could carry under their arm, as compared with the lorry-sized systems then available, as well as marketing several CO2-based cutting and engraving systems for industrial and artistic applications.

He spent much of the next 25 years installing his lasers in planetariums across the US, as well as performing on his concert lasers. This led to lecturing about lasers and optics to students of all ages, as well as becoming the “ad-hoc technician for several budgetless educational institutions”.

Eventually, he left the company in the hands of his sons and took early retirement, settling in an old farm cottage near Tullamore, Co Offaly.

“A new planetarium was built in a Donegal museum during that time,” he says. “When the museum’s board of directors decided to enhance their attendance figures by instituting laser shows, they rang the man in America who had built their planetarium and asked him where they might find the best laser display designer in America. His answer was, ‘Tullamore’.”

What’s so brilliant about your job?

“Everything – the people I work with, the technology, the opportunities to promote science education, they all combine into a brilliant package. I’m a techno-nerd who has been entrusted with a state-of-the-art multimedia domed theatre and given carte blanche to promote science, our museum and Inishowen through what even I consider some fairly outrageous means, such as sport rocketry.”

What do you like least about your job?

“The hours. Although I designed the museum’s concert laser system as simply as I could make it, it is, nonetheless, extremely complex, both in terms of operation and maintenance. I’ve yet to find an understudy with the proper electronic, optical and musical credentials to both play the instrument in concert and maintain it in working order, necessitating a seven-day-per-week schedule for me during the summer season.”

How do you spend typical day?

“I hit the deck around 6 am, spend the first two or three hours solving problems for or consulting with business associates in America via email. Then I spend the rest of the morning ’slaving over a hot laser’, cutting and engraving everything from artistic one-off items to “tourist stuff” for various customers around Ireland.

“Around noon, I head for the museum, where I power up the planetarium and give shows all afternoon, ranging from Sir Arthur C Clarke’s planetarium production, ‘The New Cosmos’ to a children’s show called ‘Larry Cat in Space’ to performing ‘The Full Irish Laser Concert’ on the laser system.”

Does your work require a lot of equipment?

“Six or seven computers and a dozen or so lasers (I lose count) as well as video and slide projectors, a complete TV studio, DVD-authoring equipment and the planetarium instrument, itself. Not to mention all the explosives.”

Are you a science nerd?

“I believe that if you look up the term ‘nerd’ in the dictionary, the definition will be ‘Ash McFadden’.”

Did science give you a buzz at school?

“I was president of my high school science club and managed not to get expelled, despite blowing the windows out of the chemistry lab. (Twice.) It would be difficult to say who was the buzzer and who the buzee, but our science club and our advisors all managed to survive my leadership, have a grand time and learn a lot of science without incurring too much expensive property damage.”

What has been the highlight of your career to date?

“That would really depend on the time, because I’ve had several mini-careers which led to this one, each with its own highlights. I was seriously chuffed in 1993 when I was nominated for the International Laser Display Association’s Lifetime Achievement Award, referring to me as ‘an icon of the laser industry’.

“It would be difficult to say whether I was more pleased then, or, earlier, when I performed stunt-piloting acts in air shows, or when I met Werner Von Braun, Willy Ley, Robert Heinlein and Isaac Asimov (together), or when I was onstage with music stars like Dick Clark, The Beach Boys, Hermans Hermits, The Drifters, Miriam Makeeba and Van Morrison (not together, thank goodness).

“Truly, though, I think living and working where I do is the highlight to top them all. Lots of people pay to holiday on Inishowen. I get paid to be here. Not much, mind you, but is that cool or what?”

While at Cambridge University during her Ph.D., Jocelyn began working on a radio astronomy project using a telescope she herself had helped to construct. She was responsible for monitoring the daily recordings from the telescope, which proved a tedious job until, in November 1967, she began to take notice of unusual signs on the recordings.

After playing with theories of reflections from the moon, or even extraterrestrial origins, Bell noticed that the unusual radio source remained fixed with respect to the stars and was therefore beyond the solar system. Over the next few months, she discovered 3 more pulsating radio sources.

The signals were coming from pulsars.

Burnell was awarded the prestigious Michelson Award with her former graduate advisor Anthony Hewish in 1973.

The following year when Sir Martin Ryle and Anthony Hewish were awarded the Nobel Prize in Physics “for their pioneering work in astrophysics”, Jocelyn was not acknowledged or recognised for the discovery.

Many astronomers felt she should also have been awarded the Nobel prize. Today Jocelyn Bell Burnell is still working on the advancement of astronomy and is presently Professor of Physics and Department Chair at the Open University, England.

WHS Monck first measured starlight electrically in 1892

WHS Monck (1839-1915) studied science with distinction at Trinity College Dublin. He trained as a barrister but had strong interests in many other areas from his student days on. He remained particularly active in two of these for much of his life – philosophy and astronomy.

Philosopher

Monck was well-known for his work in philosophy (Greek for love of wisdom), the rational search for the truth about the nature of humankind and the universe. Natural philosophy is considered the precursor of what is now called natural science, especially physics.

He was one of a number of late 19th-century thinkers who went back to dealing with classical philosophical questions, such as how humans perceive our world. He spoke out against George Berkeley, one of Ireland’s most famous philosophers. Berkeley’s early 18th century Essay Toward a New Theory of Vision claims that our thoughts are based only on what we can see and touch in our surroundings. Monck disagreed, but also objected to the contrary view that our ideas about our world are innate.

Astronomer

Monck’s interest in astronomy may have been due to the fact that he grew up near Borris-in-Ossory, Co Laois and as a boy could have seen Lord Rosse’s great telescope. He had a 7

Claire Raftery - studying for a PhD in Solar Astrophysics

What were the main ‘career decision’ milestones in your life so far?

My decision to take applied maths in secondary school was an important one. Not only did it set me up to choose a career in physics, but as the only girl in the class, it showed me that gender does not matter in this field.

Choosing to study astrophysics at the end of my second year in university was the other major milestone. I decided to follow this path because it was an interesting way of applying everyday science in an extraordinary way.

I can remember making the decision – I was outside the planetarium in the Smithsonian Air and Space Museum in Washington DC and decided that this was a really interesting take on “regular” physics!

By taking physics with astrophysics, I was allowing myself the freedom to follow a career in either subject.

Who are the people who most influenced your career direction?

My parents gave me the freedom to follow whatever path I chose. They never put any pressure on me to go in any particular direction but encouraged and supported me in any decision I made.

My maths/physics/applied maths teacher – Mr Phil Stack – had a large impact on my decision. He taught these three subjects during my Leaving Cert years.

The continuity between the three courses made me realise the importance of not isolating one subject and the importance of studying the big picture. This is something I have carried with me right the way through university.

What are the main challenges in your job?

The main challenge is combining many different aspects of physics (atomic physics, hydrodynamics, fluid mechanics, thermodynamics etc) in a coherent manner in order to explain the phenomenon I am studying.

Other daily challenges include keeping up with the literature, debugging code and understanding the technicalities of instrumental effects. I struggle with time management.

There are many different aspects of this job – data analysis, paper writing, paper reading, proposal writing. They all need to be done and it is easy to get stuck on one or two and ignore the others.

What’s cool?

I get to study the Sun! I think that is very cool. The ball of plasma that we take for granted is, in fact, a highly variable and dynamic system and the fact that we can see the different phenomena at work (solar flares, CMEs, auroral activity) is fascinating.

To see the EUV (extreme ultraviolet) Sun for the first time will take your breath away. The other obvious cool aspect to my work is that I get to work at NASA for about four months of the year. This means spending time in Washington DC working with the experts in my field of research.

What’s not so cool?

Writing scientific journal articles. I was never very good at languages in school and was not really aware of the importance of paper writing when I decided to follow this path. But in this society it is “publish or perish”.

What particular skills do you bring to your workplace?

I am a good team player. It is important to be able to share problems and solutions with others in the group, in order to progress in your work. It is very difficult to succeed on your own with no guidance or advice.

At the same time, it is vital to be able to work through problems on your own. At the end of the day, you are the one that will need to understand every aspect of your work.

I am good at networking and at selling myself and my work to others in order to progress in the field. Lastly, I am good at interpreting physics.

In this field, all you have to work with is what observations can show you. It is my job to take the observations and combine them with theory to try to explain “why” we are seeing what we see.

What subjects did you take in school and how have these influenced your career path?

English, Irish, French, maths, geography, music, physics and applied maths. Maths, applied maths and physics were the three subjects that set me up for my career.

I also took two years of chemistry in university that helped me to better understand the atomic physics I am currently employing.

What is your education to date?

I have my Leaving Certificate, a Bachelor of Arts Moderatorship degree in natural sciences – Physics with astrophysics from Trinity College Dublin.

I am currently working towards a diploma in statistics (not necessary, just useful) and a PhD in Solar Astrophysics.

What has been the most rewarding event in your career so far?

Receiving the Catherine Macaulay Award for leadership in my final year of secondary school.

What personal qualities do you have that helps you in your career?

I am highly motivated and I do not like to be idle. I like to push myself to the limit and to prove that I can achieve. I am patient and punctual and though I can be scattered, I am generally quite organized when it comes to work.

What is your dream job?

I would love to be an astronaut. That really is physics at work!

What advice would you give to someone considering this job?

Stick with it. It is a bumpy ride but everyone has their good and bad days and in the end, the pay-off is worth it. To actually get the job, make sure you work hard (you do not need to be number one in the class or have straight As – though they do help).

To ‘fit’ this job, you have to be good at working in a team and on your own. You need to be able to talk about your work with others and then put your head down and work out problems by yourself.

The goal of this job is to become an expert in your chosen field and the only way to do that is by failing and trying again, so patience is very important.

What are the three most important personal characteristics required for the job?

Patience, determination and a desire to look beyond the obvious.

What kinds of work experience would provide a good background for this position?

Anything involving computers. Research experience in a lab.

Dr Maura Rabbette - Astrophysicist

What have been the main milestones in your career so far?

My first was when I was about 12 years old, when I bought a pair of binoculars and spent many nights observing the starry sky. That was the beginning of a lifelong passion for astronomy.

I took physics and chemistry for the Leaving Certificate, then did a BSc in physics and followed it up with a PhD in astrophysics.

For my thesis I observed some of the most distant and active galaxies in the universe, using the European Space Agency’s most powerful telescopes on the island of La Palma.

How did you go about getting your current job?

Shortly after completing my PhD I applied for a US National Research Council postdoctoral research fellowship, to work in the Space Science Research Laboratory at NASA Ames Research Centre, California.

This research programme, also known as the NASA Postdoctoral Program (NPP), gives US and non-US citizens the chance to work at NASA.

It’s an excellent opportunity for Irish postdoctoral scientists and engineers to engage in ongoing NASA research programmes.

On completing my fellowship I was offered other opportunities to stay on at NASA as a research scientist which I was delighted to do – and, of course, living in California has its added benefits.

I would strongly urge any student in Ireland interested in working for NASA to look up its postdoctoral programme.

What are the main tasks and responsibilities?

Over the last decade I have been fortunate to work on some of NASA’s major projects.

I was principal investigator on a project which studied the greenhouse effect on Earth and its implications for other planets. We used a number of NASA’s Earth observing satellites and investigated the strong coupling between ocean warming and greenhouse radiative feedback.

We also looked outwards to other planets, for a better understanding of how our own planet has evolved. We estimated the “habitable zone” – that’s the distance from a star where liquid water can exist on the surface of a planet – of other planets way beyond our own solar system

In recent years much of my time has been taken up with the Kepler project. It’s a very exciting project in which one of the most powerful telescopes ever created was launched into space to look for planets similar to our own.

The challenge is to find terrestrial-size planets where liquid water, and possibly life, might exist.

My responsibilities included development and testing of computer algorithms for automatically analysing the light from thousands of stars in a search for orbiting planets.

I also carried out Kepler instrument tests to ensure that mission requirements were achieved.

What’s cool?

It was very exciting to be part of the Kepler science team and to witness the amazing night launch of NASA’s Kepler spacecraft on board a powerful Delta II rocket from Cape Canaveral, Florida.

It was history in the making, because Kepler is NASA’s first mission that seeks to find out if the Earth is unique in the universe.

For the first time in human history we will know if there are Earth-size planets capable of supporting life beyond our solar system.

Having a career as a research scientist also offers many opportunities to work outside the office or laboratory. During my PhD and while working at NASA I’ve spent weeks, sometimes months, in places such as Alaska, Hawaii, Florida, Canary Islands, Japan and Europe.

What is your education to date?

• Leaving Certificate, including Maths, Physics, and Chemistry
• BSc in Physics, NUI Galway
• PhD in Astrophysics, University College Dublin

What aspects of your education have been most important for your job?

It is important to get a broad but good grounding in as many subjects as possible at the Leaving Cert and undergraduate levels, because these will be the tools of your trade as a research scientist.

Apart from studying physics for my BSc, I also studied maths, applied maths, numerical analysis, statistics, chemistry, computer programming and astrophysics.

Finally, English is important because, as a scientist, sharing information is an integral part of your work. You have to continuously write papers, reports and proposals and give oral presentations at conferences and seminars.

What have been the most rewarding events in your career so far?

For my PhD research I used large optical telescopes to look deep into the universe. It was very exciting to find active galaxies with evidence of giant black holes at their centres.

I suppose the European Space Agency fellowship, and then the NASA postdoctoral fellowship, were great milestones in my career – they opened up many opportunities for me.

It was a memorable occasion to be surrounded by family and friends as I watched the spectacular launch of the Kepler spacecraft as it started its mission.

What are the three most important personal characteristics required for the job?

• An inquisitive mind
• Being self motivated and enjoying your work
• Perseverance – being able to pick yourself up, dust yourself off and tackle the problem from another angle

What kinds of work experience would provide a good background for your type of work?

I would recommend applying for space science or astronomy summer schools.

While working on my PhD I was fortunate enough to win a European Space Agency fellowship to represent Ireland at the International Space University summer school in Barcelona.

It was a great opportunity to study and work with astrophysicists, astronauts, space scientists and engineers from over 40 countries. It was a fantastic academic and cultural experience.

I became part of the ISU alumni network and as a result I have friends and contacts in various universities and space agencies around the world.

Dave McDonald, Astronomer

What were the main ‘career decision’ milestones in your life so far?

I was asked to volunteer for a role as a safety representative by my colleagues in a supermarket. I found the role rewarding and interesting.

Whilst my day job involves a lot of science and I’m qualified in areas such as acoustics, ventilation engineering, ergonomics, human physiology, epidemiology etc, my hobby is astronomy.

As regards astronomy, as soon as I had my first look at the Moon through binoculars I was hooked. The wonder of the night sky and where we all fit into the great scheme of things has enthralled me ever since.

Who are the people who most influenced your career direction?

The careers guidance office was absolutely fantastic and extremely helpful. They interviewed me (more of a chat really) and we discussed what it was that I wanted to do – it wasn’t really a discussion about jobs, just what I liked to do and what things interested me and science came top of the list.

They quickly identified a third-level qualification I could try for and they even arranged an interview with the polytechnic. It was all plain sailing after that.

As regards astronomy, even though it’s not a “job”, the prime motivator for me was a colleague, Eamonn Ansbro, who was doing some scientific work for a PhD. After chatting with him extensively, I decided that I was going to follow that path as best I could.

And sure enough, a few years later I’m providing quality data to the Minor Planet Centre and sending in data to the Jet Propulsion Lab in support of the Dawn Mission.

Does your job allow you to have a lifestyle you are happy with?

My profession is a “caring” profession – I am involved in protecting people’s health at work. I guess that’s one of the reasons I chose it.

It certainly has been very good to me on the earning front. And while it has taken a few years to save up for life’s “luxuries”, I am certainly in a very healthy position to take great vacations, have a nice house and spend a significant portion of my earnings on my hobby.

Describe a typical day

There really isn’t a typical day in health and safety. There are common themes though – lots of questions from clients, deadlines to meet, novel or complex problems that take time to work through and a need to communicate all this in plain understandable language.

For the astronomy side of things, a typical day would involve checking the weather. If we’re all go for a clear night, it’s a case of planning targets, writing scripts for the automation software and then getting the equipment ready for a night’s run of taking images.

The images are then analysed and data generated. Thus is then formatted before being sent to the Jet Propulsion Lab or the Minor Planet Centre.

What are the main tasks and responsibilities?

I am required to carry out consultancy work and training.

Consultancy involves carrying out noise assessments, chemical/biological exposure assessments, thermal comfort surveys and working with people using display screen equipment (VDUs) to make sure they are safe and healthy.

I carry out training in a wide variety of health and safety subjects and train all kinds of people from operators through to directors.

Along with all of this, I have to keep up to date with all the latest legislation and guidance coming out of the EU and the Health and Safety Authority.

With the astronomy, the main tasks are reporting positional data on asteroids. Some are far away, some are close by and warrant us keeping a close eye on them to see if they might come a little too close for comfort.

What’s “cool” about your job?

I don’t know about cool, but there is a buzz – even after 25 plus years in the profession – when you do something that changes someone’s viewpoint on health and safety and they start to do things the right way in order to protect themselves.

There’s loads of cool stuff with astronomy.  I’ve been fortunate enough to do some work with RTÉ – both live and recorded. I even got to do a film review on the Moon landings.

As well as meeting the RTÉ folks like Dave Fanning and Derek Mooney, it’s great to communicate the message that astronomy is interesting, fun and very accessible to everyone.

The coolest astronomy thing, though, has to be having an asteroid bearing my name. With all my achievements, one very kind colleague put my name forward to the International Astronomical Union and they named asteroid number 21782 after me.

So asteroid Davemcdonald will be whizzing around the solar system for a few billion years after I’m well gone. Now that’s cool!

What particular skills do you bring to your workplace?

I think the most important quality is communication.

You really need to get your message across quickly, simply and accurately, especially when you’re talking science. It really doesn’t help if you come across as an egghead!

What aspects of your education have proven most important for your job?

The basic school subjects of maths, chemistry, biology and physics were crucial.  Unfortunately, I was rubbish at higher level physics but it didn’t have a detrimental effect.

I’ve managed to learn enough physics to keep me going.  I have to say that English was also very important.

I usually communicate in writing reports – they need to be clear, concise and grammatically correct. English was a big help and I did much better at that than physics.

The IT diploma was a real boon to me. Doing formal study in that area has been a fantastic help.

What have been the most rewarding events in your career so far?

For work, I would like to think that I’ve made a positive difference to my clients’ employees. If I have prevented an accident or someone getting sick or going deaf, that to me is invaluable.  And I think I’ve done that on many occasions.

In astronomy, I would hope that my small contributions will encourage others to strive for more, and perhaps one day Ireland will be able to match its past achievements in this area.

What is your dream job?

I’d love to have the Hubble telescope all to myself. Of course, I would need a control room kitted out with all the latest computer gadgets, a good sound system for music and a well stocked fridge.

A 70-inch plasma screen for watching movies on and playing Halo would be mandatory for break times. Heaven!

What advice would you give to someone considering this job?

A caring attitude is essential for Health and Safety – you need to be passionate about getting the message across to people and telling them why it is so important. After all, no-one wants to see anyone suffer harm or be in pain.

For astronomy, a yearning for answering the unanswered questions is a must. You also need to be dedicated and focused and not put off by the weather

What type of work experience would provide a good background for this position?

Working for a large manufacturing or construction company and being assigned to a health and safety professional for a few weeks would be great – you’ll quickly know if it’s for you or not.

For astronomy, if you could get someone to show you Saturn, live, through a telescope, I guarantee you’ll be hooked.

Caitriona Jackman - Planetary Scientist

What were the main ‘career decision’ milestones in your life so far?

I always had a leaning towards maths and physics, and after the first year of my undergraduate degree at the University of Limerick I went with 20 Irish people to the London International Youth Science Forum.

This is an annual two-week science trip for people from all over the world. We had lectures on all types of science, and also day trips to universities and research centres near London.

I went out to the Mullard Space Science Laboratory, part of University College London, and was fascinated by the people I met there.

In the third year of my degree we needed to find a nine-month work placement, and I ended up going back to the Mullard Space Science Laboratory.

There I worked on Cassini data (from the Cassini space probe) for the first time, and that sparked my interest to go on and pursue my PhD in planetary science.

Who are the people who most influenced your career direction?

My parents have always been extremely supportive, both emotionally and financially. I was self-funded for my PhD – as a non-UK student I was ineligible for funding from the research council there.

I have always been pretty sure of what I wanted to do, and have been very lucky to have supportive family and friends, and to have encountered many good opportunities along my path.

My PhD supervisor at Leicester was also a great inspiration, very knowledgeable and helpful.

What education and qualifications do you have?

• Leaving Certificate (including maths, chemistry and physics)
• Applied Physics at the University of Limerick, final-year dissertation on “Galaxy formation and self-organised criticality”
• PhD in Planetary Science, University of Leicester. Thesis: “Solar wind magnetosphere coupling at Saturn”

Does your job allow you to have a lifestyle you are happy with?

My job is very flexible time-wise, which is good as I would definitely not describe myself as a morning person. It is also quite self-directed.

When I have deadlines, or when I’m feeling extra inspired or motivated, I work long hours, some evenings and weekends. In contrast, there are quieter periods where the working hours are not so rigid.

The travel to international conferences is also a great perk. I feel very lucky to do my job.
