Winners of the BT Young Scientist and Technology Exhibition Eric Doyle and Mark Kelly receive a hero's welcome on returning to their school Synge Street (CBS) in Dublin.

The judging panel of the BT Young Scientist and Technology Exhibition were impressed with the duo’s exceptional Young Scientist Exhibition project entitled ‘Simulation Accuracy in the Gravitational Many Body Problem’.

Mark Kelly explains the project which has developed new algorithms with far reaching applications.

We just came up with a more accurate and efficient way of calculating where a satellite is going to be in space at a specific time.

The inspiration for their project was a breakthrough made by Irish mathematician Diarmuid Ó'Mathúna when he solved the 250 year old Euler Problem.

I have produced exact solutions for a very old problem, and it put these gentlemen in a position of assessing how well the numerical procures perform against my exact solution, and they’ve done a beautiful job.

This is the third time Synge Street CBS has taken home the top prize trophy at the Young Scientist Exhibition and the school has achieved more success in producing winners than any other school.

As well as a trophy, Eric Doyle and Mark Kelly won €5,000, tickets to the London 2012 Olympic and Paralympic Games and most importantly the opportunity to represent Ireland at the 24th European Union Young Scientist competition in Bratislava. In the meantime they must undertake the challenge of their Leaving Certificate exams.
