  • Ogham is an old Irish script made by carving notches into stones. It fell out of use more than a millennium ago - but it's an interesting exception to a linguistics and computer-science rule that I'd never even realised existed. Let's talk about the Ogham Space Mark.

    An alternate title for this video was "The Space That Isn't A Space", but that's a bit more difficult to translate into Ogham. Thanks again to all the team at the British Museum!

    What's missing from this picture becomes a whole lot more compelling, when you realize it can substitute for anything it contains. Even our modern digital computers, would never work if it were not for engineers carefully accounting for how the holes the electrons occupy moving around on their own, without the electrons.

    I have recently discovered your channel and I love it! I've been trying to stop myself from ploughing through all of your videos too quickly, so I don't run out. Thank you!

    Wouldn't it be basically the same thing as an underline? In normal underlined or strikeout text, the underline continues through spaces and across line breaks, not behaving as a character. I'd think the stemline, which itself isn't a character, could behave similar.

    I remember they taught us to read these in primary school over here in Ireland.Don't remember any of it though

    Why would a sub-Roman Irish rock carver care about computer-science rules? ... he'd have started with a bigger rock ... do we have any examples of this in the 400 or so lithics available to us right now? ... if not, then we never realized it existed because it doesn't exist, not in Ogham ... this isn't about linguistics, it's about convenience ...

    Have you ever done a video on how we tried to recover the pronunciation of dead languages?

    I don't get why this couldn't be another word divider like · in latin. What's the difference?

    It took me longer than I’d like to admit to figure out ‘Tom Scott and Ogham’.

    If only the old Irish farmers knew how much trouble they were making for computer scientists 1500 years in the future.Makes you wonder what stuff we do now that's going to be a mess to sort out in 1500 years.

    interpunkt... cool now i know what to call the space i my own invented runic language.Also mine has a option of doing them along a line or as regular characters... or to mach them all together into word glyphs that kinda look like Kanji (basically i designed it so i could use the same writing system to get styles similar to latin, runic, arabian or chinese type characters with the same alphabet just by changing how it's writen out a bit)Cool to actually know what my space dot is called... though technically i often break the line rather then have a blank line... then again i never wrote mine on the edge of something so i never needed to annotate spaces like that.
