Today, we mostly think of the fax machine as an outdated piece of technology. While there are still some uses for it in an office-setting, technological advances are sending the fax machines to the same pasture as pagers, land-line telephones, and disposable cameras. Even if this is the last we hear of the beeps and bops that echo as an incoming fax is transmitted, the fax machine had a very long life - an amazing 171 years to be exact. Yes, the fax machine was invented in 1843, before the Model-T was even a dream, before the telephone was invented, and even before the American Civil War broke out.

My personal favorite fax fact: When the Soviet Union landed the first unmanned probe with a camera on the moon, they transmitted pictures back to Earth using a radio signal that used the same protocol as a fax machine. It just so happened that the radio telescope at England's Jodrell Bank Observatory was aimed at the moon at the time of the landing, and recorded the signal from the probe. The astronomers at Jodrell Bank then made a phone call to the Daily Telegraph, who brought over their fax machine to help decode the message. As a result, even though the first photographs taken from the surface of the moon came from a Soviet probe, they were first published in a British newspaper. Needless to say, the Soviets were not amused.

I don’t know how far back this goes, certainly to my childhood in the 1950s, probably before World War II: pictures in newspapers could be taken in another state or country and sent by fax over phone or radio, and were often captioned “AP Wirephoto” or “AP Radiophoto.” The sensing in the transmitter was done by focusing a spot of bright light on to paper, mounted on a drum, and the copy was exposed by focusing the same bright light on photosensitive paper. This kind of fax, requiring manual setup by operators in each end of a phone call, was still used for short (mostly one page) time critical reports up until the self-dialing, self-answering, self-syncing, self-feeding digital faxes became available. Also, radio fax is one of the modes of transmission licensed on the amateur (Ham) radio bands in the US.

I saw an interesting sort-of-fax-machine-but-not-really back in the early 1980s when I was taking flying lessons. My instructor and I flew over to DuPage County Airport and visited the Chicago Flight Service Station (FSS). The FSS Specialist had a device that was a pen that was hooked up to a couple of senders that transmitted the X- and Y-coordinates of the pen to a receiving unit in the control tower. What ever the Specialist wrote was reproduced in the tower. When we finished up at Flight Service, we went up to he tower and saw the other end of the device. As far as I know, it was all analog, operating over two copper pairs. It might have been a single pair, multiplexed, but I don't know. My instructor was trying to teach me about how to get a weather briefing from and how to file a flight plan with Flight Service and then about all the things that the tower controllers did, but I was too busy geeking out over the remote-writing thingie.

@emorag 5 лет назад

Traditional analog faxes, and telephone lines in general, are actually not secure connections because there's generally no encryption. Anyone can plug into the line and intercept the call / transmission. But the culprit would have to be physically present and couldn't hack the analog signal remotely, which gives it an edge over digital media such as email or unencrypted digital faxes (which can possibly be intercepted remotely). That said, governments and companies who utilize secure digital encryption for internal communication can utilize encrypted digital media (including email) between remote locations without fear.

Why do swivel chairs typically have five legs?

@PileOfEmptyTapes 5 лет назад

Stability for a given size. Try tipping something over that has as little as 3 feet - it is substantially easier in some directions than in others. Basically, effective lever length is between center and the triangle connecting the support points. In an equilateral triangle, it would vary by a factor of 1/cos(60°) = 2, and it is the minimum length that determines dimensioning of the whole thing. Add more feet, and the supporting area becomes more and more circular in shape, so this variation is reduced accordingly. 5 proved to be a good compromise between stability and complexity, with a variation of no more than 1/cos(36°) ~= 1.24. The legs can then be correspondingly shorter. Yay for trigonometry. The only reason anyone still uses tripods or mic stands with 3 feet is that they are stable no matter how crooked the surface, though the reduced complexity certainly is welcome as well. Tables tend not to be high or lightweight enough for a "mere" 4 legs to be an issue.
