Gig or Jig

A fitting title to end the confusion of the proper pronounciation of gig or jig.
Gig, a prefix added to the words "Hertz" and "Cycle" is a numerical term for billion.

Like megahertz and megacycles. I heard the term, "Jigawatts" used by the scientist, Emmett Brown, the character in the movie, " Back To The Future". 

With all the concern about cellphones causing cancer due to microwave radiation, I thought I would mention it here in the K Collective.

Microwaves operate in the gigahertz range and so do computers. Their microprocessor clock cycles or speed is what gives it's computing power. Any vibration that exceeds about 100,000 cycles or 100 kilohertz generates radio waves.

The human brain operates between four to five hundred cycles per second. That is in the audio spectrum close to the key of "A" or 440 Hertz.

While talking on a cellphone when driving is obviously dangerous, it was thought talking at the same time was a distraction to the driver. I speculated it was interference from the cellphone on the brain. I believe this theory has been corroborated by studies, but it makes a lot of sense.
Microwave radiation is harmful to the human brain even at low power ranges. 

The Klystron power tube pictured on this blog operates somewhere in the kilowatt range. Extremely dangerous to humans who are in the way or in close proximity.

When NASA sends signals to their deep space probes they use acre size microwave dishes
at the megawatt level. All air traffic is cleared before making transmissions so as not  to fry any pilot flying above. Of course, any fowl in the air is instantly Kentucky Fried Chicken.

Well, enough of my microwave rants and technical mumbo jumbo.


See you later.


Ending Transmission.........


P.S.  If someone could clarify if it's GIG or JIG would surely be appreciated..
