Why I Don’t Use Spellcheck
If you didn’t know before, you do now: I tend to use British spellings. I always have and likely always will. I don’t know why, but I do. So when you see “realise,” understand that’s natural for me.
And when I use a term like “brane cosmology,” I’m referring to something quite specific. I suppose someone, somewhere, has used the term “brain cosmology,” but it wasn’t me.
To answer the question, why don’t I use the “spellcheck” feature? Spellcheck only annoys me, and I try to avoid annoyances. However, I do edit things when I find an accidental misspelling in my work.
Spellcheck doesn’t know the word brane, nor does it recognise etymalchemy, and so it’s of limited use to me.
