Title: Early research material Post by: WA3VJB on March 28, 2007, 06:28:49 AM Alan Kline over on a broadcast email reflector posted this information, and yes, you can spend all day picking around on there. Wow. For a quick sample of a given book, suggest hitting the "text" version, the smallest file type among the variety of formats they've used to scan them in.
The Internet Archive (www.archive.org) has just opened a *huge* section of scanned PDF books. This is similar to the Google project, only the Archive is doing a much better job, IMHO. Anyway, go to www.archive.org/details/americana and enter "radio", "television", or "broadcasting" in the search window to find a treasure trove of early books. Most are from the 1920's, 30's, 40's, and 50's--primary sources for research... Be warned that these are very, very large files--this is definitely *not* a site for dial-up users... Here's one from 1922. I love the approach. To the non-technical reader the transmission of speech and music with no visible means of intercommunication is somewhat of a mystery. While it is mysterious it is no more mysterious than the production and recognition of light, for radio and light waves are of exactly the same nature. The relation of radio and light waves is the same as that existing between red and blue light, it is merely a matter of frequency. Of course the " colors " of the radio spectrum are invisible as far as the human eye is concerned and the radio receiver is nothing more than an artificial eye sensitive to these extremely low- frequency " colors."

I've been posting that quote of Arthur C. Clarke as part of my signature here on the Forum for months! As I am sure you are aware, that quote is known as Clarkes Third Law. Here are his First & Second Laws: Clarkes First Law: "When distinguished but elderly scientists state that something is possible they are almost always right; when they say something is impossible, they are very probably wrong". Clarkes Second Law: "The only way of discovering the limits of the possible is by venturing a little way past them into the impossible". Clarkes Third Law (and my personal favorite): "Any sufficiently advanced technology is indistinguishable from magic". Clarke was indeed a very great man, in my humble opinion. 73, Bruce Title: Re: Early research material Post by: W3LSN on March 28, 2007, 06:15:00 PM Clarke was indeed a very great man, in my humble opinion. Not "was", "IS". The man is still alive. 73, Jim WA2AJM/3 Title: Re: Early research material Post by: KB2WIG on March 28, 2007, 07:04:38 PM .

Quote Clarke was indeed a very great man, in my humble opinion. I had the chance to meet Arthur C. Clarke when I went to Sri Lanka in 1983. Nice guy. He first started writing books about diving. When we were there, he was on the phone with Paramount Pictures about '2010' sequel. Title: Re: Early research material Post by: W2XR on March 29, 2007, 10:14:17 AM Yup, Sir Arthur C. Clarke is still very much alive; my incorrect use of "was". I believe he turned or will turn 90 years old this year. He was born in 1917. Thanks Jim/WA2AJM, for correcting me on this!

A little Clarke trivia: The term "Clarke Belt" is sometimes used to describe the orbit utilized by communications satellites in a geosynchronous orbit, and this was named in his honor. 73, Bruce |
