"Cheating at Maths Using Computers"
Damian Bevan G4WPO

For January we welcome back Damian Bevan G4WPO. A more serious title for this talk would ‘Using computers to solve mathematical problems’.

In 1936, in the ‘age of electricity’, Alan Turing presented his machine which he hypothesised was able to compute anything which is capable of being computed.

It turns out that around a century earlier, back in the ‘age of steam’, Charles Babbage and Lady Ada Lovelace had already been having similar thoughts about mechanical computing engines, designed to solve mathematical problems. In those days, human 'computers' were used to laboriously calculate and tabulate the solutions to maths problems ranging from trigs and logs, to astronomical, nautical, banking and insurance information etc.

Nowadays, computers are immensely more powerful than they were in either Babbage’s or Turing’s time. Damian will touch upon some modern computing tools, which are available to us all in order to solve every day problems, before briefly wondering whether computing has anything to say about the nature of our lives and the universe itself.
