That it is impossible for a being to possess an attribute and at the same time not to possess it) to be derived from this fundamental law of thought. 32 2 Foundations x2 = x ⇒ x − x2 = 0 ⇒ x(1 − x) = 0 For example, if x represents the class of horses then (1 − x) represents the class of “not-horses”. The product of two classes represents a class whose members are common to both classes. Hence, x(1 − x) represents the class whose members are at once both horses and “not-horses”, and the equation x(1 − x) = 0 expresses that fact that there is no such class whose members are both horses and “not-horses”.

Queens University Belfast and Queens University Galway (now NUI, Galway) were founded the same year. 2 Boole 31 neither sheep nor black. Similarly, if z = goats then y + z represents the class that are either sheep or goats. , in a manner that is similar to real numbers. Boole showed how these symbols could be used to reduce propositions to equations, and algebraic rules could be used to solve the equations. The algebraic rules satisfied by his system included: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.

The Irish Mathematician, Sir. Rowan Hamilton, (who discovered Quaternions) was another famous recipient of this prize. Hamilton was awarded the medal in 1835. Boole was elected a fellow of the Royal Society in 1857. 3 Queens University Cork is now called University College Cork (UCC) and has about 15,000 students.
