Electronic Communications









Can you send out lightnings, that they may go, And say to you, ‘Here we are!’?” – Job 38: 35











www1.  This is one of the statements in the Scripture that must have seemed fanciful – that lightning would be able speak and produce sound or more specifically, communication



  • Today, it is second nature to us – the world is run on electronic communications
  • Instantaneous communications (wireless or wired) all make use of electromagnetic radiation that travels at the speed of light
  • This is why you can speak to someone in California and hear them instantly – (re: speed of sound is only 768 mph – lightning vs. thunder) – its not traveling at the speed of sound…it is traveling via electricity at the speed of light

2.  It was a British scientist in 1864 named James Clerk Maxwell who figured out that electricity and light (waves) were two forms of the exact same thing

  • He also is the one that figured out that light could be sent and manifest itself as speech – of course, it is Alexander Graham Bell who applies this idea when he invents the telephone
  • Maxwell, Michael Faraday, James Prescott Joule (collective fathers of electromagnetism) were all devout Bible believing Christians 1

3.  How a telephone works:

  • Sound is transformed into electricity (via the microphone) and then electricity is transformed back into sound (via the speaker)
  • Microphone transforms air vibrations (which is caused by our speaking) into electric vibrations
  • Electronic circuit amplifies the electric vibrations, which in turn is sent by a microprocessor into the wired or wireless system leading out to the telephone network
  • When the phone on the other end of the two-communication receives the electric vibration, it needs to convert it back into sound – your speaker takes care of that
  • It converts the electric vibrations (which has traveled at the speed of light (186,000 mps) into air vibrations, which of course produces sound 2

4.  The Bible is accurate in its electromagnetism
