The Ernest Walton coin is being issued in recognition of Ireland’s only Nobel Laureate for science.
They were winners of the eponymously-named Central Bank Ernest Walton Award at the exhibition last Friday, which is presented to the physics project which best illustrates innovative techniques and the use of data.
The limited edition silver proof coin has an issue limit of 6,000 units, and will be available to collectors on the Central Bank website from today.
Designed by Irish artist Rory Breslin, it depicts the manoeuvres of Walton’s famous experiment, and the resulting explanation of Einstein’s famous mass/energy equivalence equation, E=mc2. The coin will retail at a price of € 44.
Walton shared the 1951 Nobel Prize in Physics with colleague John Douglas Cockcroft as a result of a pioneering experiment where they split a lithium atom using accelerated protons, which informed their critical findings on Einstein’s theory.
