Lay fax record

evening everybody although today taken for granted that every office has a fax machine only a few years ago it was almost unknown its recent appearance has made it to a wonder of the age and there is something quite magical about the way it converts a bit of paper into a stream of odd warbling noises and then reassembles it all at the receiving end but although it seems quite magical the basic way it works is actually surprisingly simple we're going to demonstrate this principle with a human fax Rex has got a big bit of paper just over the ridge and I'm going to fax this message to him using these flags the signal to him we're going to walk over our bits of paper using metronomes to keep us in step and I'm going to hold up the green flag to signal the start of each line I'm going to hold up the red flag whenever I step on a black bit of paper what's happening inside a real fax machine is surprisingly similar there's a sensor that reads a line at a time at the sending end and a printer that prints out a line as time at the receiving end the lines are usually much too small to be visible except at the tiny writing at the top of a fax which identifies where it's come from of course as a mass of electronics underneath that converts the lines to sounds that can travel over the telephone but the basic idea is exactly the same as our human fax it's so simple it was first patented 150 years ago long before the era of electronics and over 30 years before the invention of his phone the inventor was a Scotsman Alexander Bain who came from a remote Croft in Caithness didn't do it must be mortal - sheep his interest in the new science of electricity was inspired by a lecture and he started experimenting in 1840 buying only a coil of wire he used cattle jaw bones for hinges and head of the springs he made batteries by sinking plates of different metals into the earth teach about the inner workings of the clock jung-min during his apprenticeship invented the first electric clock what have you done looks are the first electric clock this hideous oh we there's no place for me here to London I and I'll invent the first fax machine Baynes fax machine was inspired by an earlier discovery that paper soaked in potassium ferrocyanide turns black when electricity is passed through so if I put it on this metal plate and move a nail across it it should change color when I complete the circuit brain had the idea of using this paper to receive messages assembled out of printers type so if thumb Rex was a bit of help from Percy and me moves his nail across the raised part of a bit of pipe while I move...
