Camrysfa Turbocharged April 19, 2015 Share April 19, 2015 http://www.thestar.com.my/News/Regional/2015/04/18/Maths-professor/ SINGAPORE: The man behind the "Cheryl's birthday" viral poser is a mathematics professor from Singapore's National Institute of Education (NIE). Dr Joseph Yeo Boon Wooi, who is in his 40s, is part of the panel for the Singapore and Asian Schools Math Olympiads (Sasmo), the largest math competition in the country. He helps set the questions each year for student "mathletes". This year's competition took place on April 8. The puzzle in question was leaked, and subsequently posted on Facebook on April 11 by local TV presenter Kenneth Kong, who initially mistook it for a Primary 5 question. Dr Yeo, a recipient of the prestigious Nanyang Excellence in Teaching Award in 2013 and first author of the New Syllabus Mathematics used in secondary schools, said he first chanced upon a Facebook post discussing the birthday logic problem on April 12. But it did not ring a bell until he saw the photo of the question. It has since been featured on international media such as The New York Times, The Guardian and the BBC, and was a top-trending story on US site Buzzfeed. On April 16, "Cheryl" even got her own cartoon on The New Yorker. The Straits Times caught up with the media-shy math whiz and persuaded him to answer some questions about himself and how he came up with the viral hit that has confounded the world. Dr Yeo's birthday, coincidentally (or not), falls on July 16 – the answer to the puzzle. 1 Link to post Share on other sites More sharing options...
