I’m partly in distraction mode, but I really do need all my sources carefully sorted so that I can finally start cropping images for my thesis. I’m calling it this to help my focus, and how to present it all.

A thesis is an idea or theory that is expressed as a statement and is discussed in a logical way.
A thesis is a long piece of writing based on your own ideas and research that you do as part of a university degree, especially a higher degree such as a PhD.

I’m using dissertations as well as using them for formatting.

But I’ve now got a really good way to explain the engineering evolution which also helps explain why the language is so difficult to unpick.

There is a solid 50 year gap in almost every artform and every archive that covers my thesis. So that is why I’m being extra careful about applying that a few documents/images suggest.

And there is also caution when using transcriptions that formalise spelling- it has already led me stray several times.
