I think that they mean in this source this /particular/ way of diagrammatic reasoning, as pioneered by Coecke, who literally wrote the book on it (http://www.cambridge.org/gb/pqp), although very similar diagrammatic reasoning has been used for some time in Category Theory through string diagrams (https://en.wikipedia.org/wiki/String_diagram).

It's funny reading the comments in here; when this first got retweeted onto my twitter timeline I thought it was just a picture of someone's dressing table and the tweet was a joke about (lots of) men not being able to recognise makeup products ...

I'm not the person you replied to but I read the Diana Burgin & Katherine Tiernan O'Connor translation and thought it was absolutely brilliant!

I feel like the difference lies in that Warwick (and some other UK universities who do the same thing, including my own) do still have a relatively high barrier to entry that sets them apart from the American for-profits.

Not to say that Warwick & other institutions aren't as for-profit as places like Corinthians, but they definitely manage to get away with it by still maintaining academic excellence.
