"Unusual Club of the FBK"
Peter Ebsworth LB0K / G8CBK

Our December talk on Tue Dec 7th will have a seasonal Nordic flavour as we get closer to Xmas:

Peter Ebsworth, LB0K / G8CBK, will talk about the history of broadcasting around the city of Bergen in Norway and especially of the transmitting site at Erdal which includes a Marconi transmitter, that is now a venue for Norwegian Amateur Radio Club LA1ASK.

On site are former Telefunken and Marconi broadcast transmitters. One of the remits is to continue broadcasting from the site, as a museum activity and to keep a (national) presence on the Medium Waves, on 1314 and 1611kHz.

    "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 everyday problems, before briefly wondering whether computing has anything to say about the nature of our lives and the universe itself.
