If the Greek and Cyrillic characters are only in the encrypted text, there would be no need for such a distinction.

Unfamiliarity with Cyrillic and Greek letters wouldn't matter if those letters are only in the encrypted text.

What if the enigma machines used by the Germans during the wartime encrypted text using a mixture of Latin, Greek and Cyrillic, instead of the encrypted text consisting of only latin characters. Enigma encrypted text consisting of Latin characters looks like this: ZAJ IRARKF ZLTV DH SDR VQZK...

If the first two colonies to build railways both standardised on 5'3'', then maybe the railways linking all the state and territory capitals would be Irish rather than English gauge. Australian rail vehicle manufacturers would be tooled for that gauge, and not English or Cape gauge. That New...

So some of these advances were in the late 19th century, that was when steam engines were still used extensively. Thing is that most others were in the mid 20th century, but even then, Heliostats didn't catch on.

I but windows have been a feature of buildings in civilisation since long before the industrial revolution. I didn't know that big windows used to be status symbols. But heilostats don't necessarily require big mirrors, they could surely use more smaller ones. And how modern is 'modern' in...

Heliostats are gaining popularity as an economical method of daytime indoor lighting in sunny places. But this trend seems quite recent in relation the technology behind heliostats, these having been invented centuries ago. Some solar power stations have heat storage, usually with molten salt...

Television broadcasting and video recording seem to be quiet an ample topic for alternative history, and a format called the capacitive electronic disc was introduced unusually late in relation to the technology involved, and paradoxically, after the laserdisc. What if a grooved videodisc...

Sydney's splendid suburban railway network was largely designed by Dr. John Joe Crew Bradfield. It has the highest capacity of any suburban railway network in Australasia, with very few level crossings, additionally, all it's trains are double decked. But there are some low capacity stations...

And there was no demerit system either.

Even the US and Canada seem to have lower blanket speed limits than a lot of European countries, in spite of lower population desities and less comprehensive railway networks. I would imagine that enforcement, on the other hand, is stricter in many European countries, especially Germany and...

Most phono catridges are passive transducers, where a small signal voltage is generated by stylus movement. The higher the output needs to be, the greater the tracking force. Back when in the 1940s microgroove discs first appeared, I don't know about today, this approach required a tracking...

Audio tape recorders at radio stations in the analog era also recorded signals for the puprose of playing over the air. But in case of FM stereo radio stations I imagine they didn't record in quite the same format as they broadcast. FM stereo broadcasting is component stereo, with a side channel...

Well okay, a black a white tape machine would be easier to convert to composite rather than component. But weren't those tape machines designed with colour in mind right from the start? It seems that the idea behind video recording was to replace film in the same way that electrical audio...

The first video tape recorders, these being Qudruplex machines, first appeared in 1956, in the same country that previously pioneered colour TV. Yet the Qudruplex tape format, and all subsequent VTR formats, until the 1980s, were all composite video. Now, composite video was introduced as a way...

I didn't know about the origins of Pepsi or Subway, I knew that Coke was originally Georgian and forget to mention that. But if you look closely, I did put southwestern in brackets. The southwest came to mind because of how liberal and radical it is. I've never heard of White Castle. Pardon the...

Let's get it straight So all the parts for acoustical recording were there, probably since the industrial revolution, but nobody seemed to put them together until thirty odd years or so before electrical recording, which in turn did contain parts unknown or then only recently known to amateur...

I did note that the world wide web was founded in the UK. Though it does, in many ways have that liberal feel to it. As for "political" leanings, they actually come into play with the popularisation of, in particular, the world wide web. It's similar to the leanings that came into the advent...

So the internet actually has millitary origins. When I think of the internet, I think of the world wide web, and I'm sure many others do it. It was founded in the UK, but nevertheless, much of the internet does have a liberal feel to it.

Microgroove records originally appeared as a monaural format, with horizontal grooving. When they appeared in stereo, they adopted a combination of horizontal and vertical grooving. This lead to stereo crosstalk, and also meant that bass and treble needed to be more limited than on mono records...
