Maths Week celebrations kicked off early in Arranmore with over 60 students from Gairmscoil Mhic Diarmada enjoying a mind boggling performance by world renowned mathematician and master of cards, Colm Mulcahy.  The week began yesterday when Colm entertained and revealed the maths behind some of the world’s most known card tricks to the students of Arranmore.

Having earned his B.Sc. and M.Sc. from University College Dublin, Colm then attended Cornell University where he received his PhD before moving to Atlanta, Georgia where he has been lecturing at Spelman College in Mathematics since 1988.

Professor Mulcahy is recognised as an authority on the mathematical principles and effects that most card tricks are based on. Recently, he has published a book titled ‘Mathematical Card Magic: Fifty-Two New Effects’ which offers readers an entertaining look into the magic behind 52 self-working magic creations that require only maths.
