On Saturday 19 September, Francis Clarke, member of the Council of the London Mathematical Society, officially opened All Angles Covered, a display and series of events celebrating Tenby born mathematician and inventor of the equals (=) sign, Robert Recorde (c.1510 – 1558).
In his opening speech Mr Clarke said, “The LMS is this year celebrating its 150th anniversary by organising an enhanced programme of events of many kinds. In particular we are pleased to support this exhibition on Tenby-born Robert Recorde, one of the several taking place around the UK under the theme of local heroes.
“As the exhibition makes clear, Robert Recorde was a multi-faceted character who did much more than what he is most known for, the introduction of the equals sign.
“In Mathematics, notation is essentially arbitrary – we use the variable x in algebra, but it doesn’t really matter if you prefer to use y. But sometimes the choice of a good notation can change the way we think about and do mathematics. That is certainly the case for the use of Arabic numerals of which Robert Recorde was an early exponent in English, as well as for the equals sign.
“So on behalf of the London Mathematical Society I wish every success to this exhibition in celebration of Robert Recorde. I am sure that those who visit it will come away delighted to have learnt more about this fascinating figure and his gifts to the world of mathematics”
All Angles Covered runs until Saturday 30 October.
