Braille is a tactile writing and reading system for the blind and visually impaired. It was invented by Louis Braille when just 15 in 1824. Respect! I don't know about you, but when I've tried braille on signs occasionally, it's always seemed difficult to train my fingers to differentiate the shapes and the dots. Perhaps it would have helped if I'd known how it worked.

Braille is based on a pattern of 6 dots, like a 6 on dice, with different letters, numerals, or sounds being different combinations. It doesn't match the shapes of written letters though, instead breaking the alphabet up into groups of 10. The first 10 letters are combinations of the top 4 dots. The following 10 letters repeat the combinations and add dot 3 in the bottom-left. Then the remaining letters, except w start again adding with dot 6 added. W wasn't in Louis Braille's original French alphabet so appears tacked on at the end.

Since its invention, it's gone through multiple iterations and languages, and there are combinations for punctuation (some common ones formed by shifting down the original 10 combinations), numbers, accented letters, maths symbols, and more. There is also agreed-upon shorthand where a letter may mean a common word eg l for like, and there are contractions where a symbol may mean a sound or set of letters like 'ch'.

The sketch shows the Latin alphabet for modern English braille.

How do you avoid confusion when spelling things out verbally, particularly when the sound isn't clear or there may be background noise? So, for example, something like Y I V B D T doesn't unintentionally get heard as Y Y B P D D. Or perhaps as I Y P V T D. A lot of letters sound similar.

A phonetic alphabet, or spelling alphabet, is a way to ensure all letters are unambiguously heard correctly by using words starting with each letter. The set of words was chosen from 1,000s of tests, including real-life ones, to maximise clarity and avoid overlapping sounds with other letters that might cause mix-ups. When written out they include deliberate misspellings Alfa and Juliett to avoid misinterpretation.

The NATO phonetic alphabet is a standard one, but there are other variations.

One of the few books I've read all in one sitting is Metaphors We Live By, by George Lakoff. It was so fascinating learning how some of the most fundamental concepts we use to govern our lives are understood through metaphor. For example, one understanding of time is through our experience of space, so it seems natural to say, the hard times are behind us, or, I'm looking forward to the future. Or that Ideas Are Objects so you can give someone an idea, or toss a few ideas around. Or that Understanding Is Grasping, so you can get the idea, or get to grips with a concept.

Primary metaphor is a theory of how these metaphorical understandings may form when we're young as we associate abstract ideas with direct experience.

So it's natural that, when we're young, important things are often big and can exert control over us, leading to Important Is Big — Tomorrow's a big day, it's just a little thing, It was a huge deal.

Or experiencing warmth when we feel affection leading to Affection Is Warmth — he greeted me warmly, she gave me the cold shoulder.

Or how sometimes to know something is to see something, such as when we find out what's in a box by seeing what's in a box, leading to Knowing Is Seeing — I see what you mean, that's clear to me know, I'm feeling in the dark on that, let's shed some light on the matter.

Other examples of primary metaphor from Philosophy in the Flesh by Lakoff and Johnson include:

More Is Up — from seeing things increase in height when there is more of them eg the prices are rising

Difficulties Are Burdens — from difficult things literally being harder to deal with eg I'm feeling a bit weighed down at the moment

States Are Locations — from associating experiences with actual places eg I'm in a rut right now, but I'll get out of it.

Bad Is Stinky — from bad things actually smelling bad eg that movie stinks

Purposes Are Destinations — from achieving goals when we get somewhere such as having a drink eg I'm going to be a star but I'm not there yet

There are many more, plus the whole world of metaphor guiding how we construct our place in the world is fascinating.

The theory of primary metaphor is from Joseph Grady.

Unless you were a maths, physics or Greek major, chances are your knowledge, like mine, may not have gone much farther than epsilon. I like how the letter names and shapes map or don’t to the Roman or Latin alphabet.

The sort of artefact that make history fascinating. Amazing to behold, a fascinating story, a controversial past and the key to the mystery of hieroglyphics.

The Rosetta Stone has inscribed on it a decree by priests honouring Ptolemy V, who was 13 at the time. The inscription is in hieroglyphic and demotic - both scripts of the Egyptian language - and Greek. Comparing the known Greek with the hieroglyphs with some remarkable talent became the key to deciphering the written language of hieroglyphs.

The Rosetta Stone can be seen for free at the British Museum. I highly recommend it. You could also read Professor Munakata’s British Museum Adventure a manga comic book featuring the Rosetta Stone.

Learning and using kind words first when travelling will take you further than others. Before I enter a country with a new language I write a list of these words and find out how to say them.

There are others too. But these are big ones. Curious? Read Metaphors We Live By was a frame-changing easy read for me.

PS Accidentally, mixed my metaphors in the final sketch. The Mind Is A Machine metaphor is so pervasive it’s hard to ‘sketch’ across thinking without it.
