How I would like to change the cell phone industry [was AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency]
"Radium" wrote in message ps.com... OTOH, AM video is boring. FM video is better. As I said before, the Y [luminance] signal should be carried on an FM wave rather than an AM wave. OK, but then, you're quite ignorant of anything remotely related to this field, aren't you? Bob M. |

FM video receivers receive Y [luminance] signals present on FM radio waves. Electrical disturbances affect the FM video receiver causing those beautifaul zapping and buzzing sawtooth patterns on the screen. You may also enjoy listening to the dial tone while standing in a glass payphone booth. |

When, pray tell, have you ever seen an "FM video receiver"? Bob M. I have one of those FM video receivers. It's my (ancient) Wavetek 3000b communications service monitor, which displays all kinds of nifty light shows and patterns for FM. I often tune it to the WX channel and watch the modulation on the scope display. It's kinda hypnotic without the accompanying audio and sometimes an improvement over what's available on TV. I guess it's TV for radio geeks. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Wrong. Science fiction has mutated into social adventure, space opera, and historical fantasy. I haven't seen any really technical science fiction in many years. Spider Robinson. Joe Haldeman. Larry Niven. Jerry Pournelle. Ben Bova. Greg Egan. Stephen Baxter. In the interest of brevity, I won't rattle off examples of how most of those authors started out with hard technical science fiction, and ended up recently writing what amounts to "future social problems" type of sci-fi. At age 74, Ben Bova still cranks out excellent stories but seems to be very light on the technology in the last few years. Stephen Baxter is a scientist and really does well speculating on where technology is sending us. Greg Egan is a mathemagician with a rather creative view of artificial intelligence. Haldeman puts me to sleep, Niven is just plain weird, and Pournelle is too militarist for my liking. They've all done "hard" sci-fi writing, but as time progresses, seem to be writing for a much different audience, such as writing for TV or movies. That's where the space opera, social adventure (chase scenes, crash and burn, and explosions) are coming from. I still read Stephen Baxter, but none of the others. This is the first I've heard of Spider Robinson, but will give his stuff a look. Arthur C. Clarke, who, thank the FSM, is still with us and writing. Yeah, but he can certainly beat the "2001 Space Odyssey" theme to death. At 89, I'm really impressed that he's still working. However, his last few books have been co-authored by Stephen Baxter and read more like Baxter's complex writing, than Clarke's neatly clipped short lines. Ok, I'll concede the hard sci-fi hasn't gone down the tubes completely and that there are still authors catering to a technically astute audience. However, even the best of these (as you've itemized) tend to drift toward the popular media, mass market, and general audience market, which deals primarily in entertainment. This entertainment is invariably devoid of technology, lacking in a basis on physical reality, and is dominated by space opera and general idiocy. For every sci-fi author that knows his science, there are perhaps 50 that are lacking. Little wonder that space opera predominates as it requires very little technical expertise to write. Maybe that's why I like reading Mr. Radium's muddled tech rants. It's the closest approximation to science fiction I can easily find. Sure, there's an AWFUL lot of crap out there - SF, like everything else, obey's Sturgeon's Law - but the good stuff is still being written. You just have to look for it. These daze, I have to do more than look. I have to dig, excavate, and filter to find it. However, I found a suitable replacement about 10 years ago. I was reading dot com business plans. Not only was I being paid to rip them apart, but the products and services were some of the best science fiction I had ever read. The authors of some of those business plans really should be writing sci-fi stories. I really miss the passing of the dot com era and the tremendous technical imagination that helped make it happen. Reminder: None of the sci-fi authors up to about 1970, ever predicted the rise of personal computah. It was always the giant mainframe (Multivac). Some came close with remote terminals, but even those had a mainframe behind them. Oh well, can't get it right every time. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

"Jeff Liebermann" wrote in message ... This is the first I've heard of Spider Robinson, but will give his stuff a look. Spider's not as "hard tech" as some of the others have been, but has been compared with Robert Heinlein in overall style. (A comparison which I am very sure he wouldn't claim himself, as RAH is a longtime hero of Spider's.) But his stuff is just an amazing amount of plain, unadulterated FUN. Try, especially, the "Callahan's Saloon" stories. Arthur C. Clarke, who, thank the FSM, is still with us and writing. Yeah, but he can certainly beat the "2001 Space Odyssey" theme to death. At 89, I'm really impressed that he's still working. However, his last few books have been co-authored by Stephen Baxter and read more like Baxter's complex writing, than Clarke's neatly clipped short lines. In my book, Clarke's earned the right to do whatever he damn well pleases at this point. And he certainly has done quite a bit besides the "2001" stuff; there's the "Rama" stories, "The Fountains of Paradise," etc...and I don't think the work with Baxter has been all that bad - you didn't like "The Light of Other Days"? Ok, I'll concede the hard sci-fi hasn't gone down the tubes completely and that there are still authors catering to a technically astute audience. However, even the best of these (as you've itemized) tend to drift toward the popular media, mass market, and general audience market, which deals primarily in entertainment. Well, as the Grand Old Man himself once noted, "Writing is like prostitution - first you do it for love, and then for a few close friends, and then for money." A writer who doesn't - or can't - write what sells won't stay around long enough to write the Important Stuff, should he or she care to do so. invariably devoid of technology, lacking in a basis on physical reality, and is dominated by space opera and general idiocy. For every sci-fi author that knows his science, there are perhaps 50 that are lacking. Little wonder that space opera predominates as it requires very little technical expertise to write. Again, though - Sturgeon's Law applies to EVERYTHING. No exceptions. Maybe that's why I like reading Mr. Radium's muddled tech rants. It's the closest approximation to science fiction I can easily find. But they sure don't seem to be grounded in anything even resembling reality. If you want hard SF, and not the sort of fantasy that makes "Star Wars" look like a physics text, you'd really have to look elsewhere. Reminder: None of the sci-fi authors up to about 1970, ever predicted the rise of personal computah. To be sure, but then, neither did anyone else. One of the nicest things about the future is that it always is full of surprises for everyone. Bob M. |

Haven't you watched the typical pre-1971 science fiction movie? The arrival of any alien object or visitor is initially detected and displayed on a large CRT, usually with an unstable Lissajous pattern or trivialized radar simulation plus the requisite shrill noises and sound effects. After seeing that demonstration, I concluded that if I was going to personally greet the Galactic Ambassador from AlGore, I would need a similar alien detector or communicator. The closest approximation I could find was a communications service monitor. In order to monitor it continuously, I decided that a 15 year career in land mobile communications was required. I would leave it running continuously, waiting for the voices from outer space. Unfortunately, the ambassador is apparently distracted and I have moved on to other professions. I still own a service monitor and still turn it on waiting for the display to mark the arrival of the alien visitors. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Reminds me of a meeting held at a large, prominent aerospace company some years back where the marketing weenie was touting the latest air-to-air missle idea that would completely dominate the market. He was a bit taken aback (but not deterred, which is another story) when one of the engineers in the audience pointed out that they needed to come up with a communications system that operated about 3 times the speed of light to make it work. snip remaining -- Jim Pennino Remove .spam.sux to reply. |
