01 / The practice

The same physics, pitched three different ways.

Background

Science communication ran alongside the whole of my PhD and has continued past it. I have presented at professional conferences, delivered invited seminars, and given talks to astronomical societies, university societies and school groups — and spent three years guiding visitors around Birr Castle Demesne, where the story runs from the 19th-century Leviathan of Parsonstown to the I-LOFAR radio telescope operating on the same grounds today.

Those audiences want different things. A symposium wants the method and the error bars; a society wants the result and why it matters; a family at a public viewing wants to know what they are looking at. I have done enough of all three to judge which one I am in front of.

The partial eclipse, live

Birr Castle Demesne, Ireland

Ireland’s partial solar eclipse of 12 August 2026 brought roughly 250 people onto the lawn at Birr. I ran the viewing across the morning: filtered telescopes on the Sun, an explanation of the geometry overhead, and questions throughout.

It is the largest audience I have spoken to. Very few had come as astronomers.

Leviathan to I‑LOFAR

Lowell Observatory group · Birr Castle Demesne, Ireland

A visiting group from Lowell Observatory in Arizona, taken from one end of Birr’s astronomical history to the other: the 72-inch Leviathan, the largest telescope in the world for most of the 19th century, and the I-LOFAR station on the same estate, part of a radio array spread across Europe.

A well-informed audience, and a technical set of questions to match.

Three Minute Wonder

The Royal Institution, London, UK

Having won the Rosse Medal at the IOP Ireland Spring Conference in March, I qualified for the UK and Ireland final of Three Minute Wonder: one research topic presented to a general audience in three minutes, with a single slide and the option of props.

The final was held in the historic theatre at the Royal Institution. Eight finalists presented to a full auditorium.

Hank Green at Birr

Birr Castle Demesne, Ireland

Science communicator and novelist Hank Green stopped at Birr during a visit to Ireland, having previously made a video about the Leviathan of Parsonstown. I gave him and his family a private tour of the telescope and the history around it.

The 388th IAU Symposium on solar and stellar coronal mass ejections, Krakow, Poland.

IAU Symposium 388

Kraków, Poland

Five days on solar and stellar coronal mass ejections, with over 150 attendees. I presented my work on a solar flare and the shockwave that followed it, and had excellent discussions with leaders in solar physics and space weather across the week.

Pint of Science, Birr

The Chestnut, Birr, Ireland

Pint of Science puts local research in front of a local audience in a pub. I organised the Birr event and recruited three speakers, covering black holes, radio astronomy, coffee as a treatment for dementia, and local ecology and biodiversity. I hosted the evening, introducing each speaker and running a quiz written from their talks.

It reaches people who would not attend a more formal science event, which is the point of it.
