Some recent studies have even shown that the speakers of "whistled" languages actually process whistles using the same regions of the brain that other humans use to process words in the usual "spoken" languages.

But why am I telling you about "whistled" languages? Well, because I recently started learning an artificial language that resembles "whistled" languages a lot. I am talking about Morse code [3]. Yes, the one used back in the days for telegraphy, where each letter of the alphabet consists of a short series of dot and dashes, or dits and dahs, and so on. It turns out Morse code is far from extinct, as it is currently in use by radio amateurs around the globe to communicate in the so-called "Continuous Wave" mode, normally abbreviated "CW" [4]. Basically, you send your message as a concatenation of long and short tones or pulses, which are then decoded by the person at the other end of the contact.

If you ever try to learn Morse code (it is totally doable in a few weeks, or even less) you will be told that you must not think of each letter as consisting of a certain sequence of dots and dashes, but rather as a "sound", a new way to "pronounce" and "perceive" the same letter you are used to reading and writing [5]. The aim is to force your brain to think of "A" whenever you hear the sound "di-daa" and to think of "R" whenever you hear the sound "di-daah-dit", without having to double-translate the sound to dot-and-dashes and then back to the images of letters that our brain constructs and keeps.

# Seeing the light of Morse

Both yargo and katolaz submitted articles dealing to some extent with Morse codeto this issue of Circumlunar Transmissions. After reading them both in my capacity as editor of this issue, I felt compelled to make a small contribution of my own in the hopes of rounding this theme out a little. The other two articles focus mainly on the use of Morse code in the context of radio. This makes perfect sense, as amateur radio is in some sense the "natural habitat" of Morse code in the 21st century (and, of course, both the authors are licensed amateur radio operators). However, as yargo mentioned, the code itself is largely independent of medium and can be transmitted using any system which offers control over the duration for which any two distinct "symbols" are present. Probably the second most frequent medium in which Morse code has been used, after radio, is light.

Instead of transmitting a radio carrier or generating an audible tone, one can turn simply turn on any source of visible light, and leave it on for the appropriate duration before turning it off again. Particularly at night time, the flashing light can be seen over long distances, especially if binoculars or a telescope are used. Not as long as a high frequency radio signal bouncing off the ionosphere can travel, of course, but longer than a shout (or a whistle) can be heard.

Using visible light to send communications using Morse code has a long history, especially in military contexts, dating back to at least the 19th century. So-called "heliographs", using a mirror to reflect the bright light of the sun and relying on purely mechanical means to break the beam were used in both World Wars and early conflicts to provide instantaneous long-distance communication without any need for electricity or cables. So-called "Aldis lamps" have a long tradition of use at sea, a method pioneered by the Royal Navy. Heliographs were also used in civillian contexts, including the US Forestry Service.
