I was a maths undergraduate at Oxford when Rubik's cube hit in December 1979. I bought my Dad one for Christmas - and then spent 4 days solving it. At my fastest I could routinely do Rubik's cube in 90 seconds, which made for lots of fun at lots of parties.

Four degrees including a doctorate later, I'm running my own small company in scientific word processing - selling, supporting and providing Training Courses in Scientific Word (WYSIWYG LaTeX). You can read more about me on our company web site.

My two courses on Udemy teach these areas of expertise: Rubik's cube Inside 3 Minutes, and Scientific Word Technical Typesetting.
