Rounds: Here.
Disclaimer: I watched this episode when it first aired, and although I
did not recall any of it I cannot rule out memory being a factor.
We've got two new contestants today, since Anthony successfully retired on Friday. First up in the champion's position is Matthew Magain, a web and phone application designer. But in addition to that he has written and published a children's book, called Charlie Weatherburn and the Flying Machine. Matthew says that it is based on an Australian mathematician names Charles Weatherburn, who lived in the early 1900s and was "quite a giant" in the fields of vector analysis and differential geometry; the central character in the book was inspired by him.
And in the challenger's seat we have Deborah Kemper, an accountant who plays indoor soccer. Richard asks why indoor rather than outdoor; Deborah explains that her husband and son were playing it, and decided that it was time to get her involved with some sport. She plays defence when she plays.
Points were shared in the first round, and then Matthew took the lead in round two. He extended it further with an excellent find in round five, but that was the last piece of good news for him. Deborah solved both remaining numbers rounds while he did not, and Matthew misheard a letter in the last letters round to end up with an invalid answer. Neither contestant could solve the conundrum, but even if Matthew could have it would not have been enough. Deborah became the new champion with a scoreline of 43 to 32.
As usual, details after the break.
