I'm a learner, an explorer, still finding my way in using technology effectively in my classroom.   Our ninth and tenth graders all participate in a 1:1 program - they are issued laptops.  Last year I explored Edmodo, Desmos, Manga High, and few other tech tools.  This year I emphasized Desmos more, used Socrative and Kahoots.  My students blogged on KidBlog.  I also Google Forms and added Flubaroo for grading.  I used Google Docs and Presentations quite a bit.In […]

John F. Nash Jr., Mathematician Whose Life Story Inspired ‘A Beautiful Mind,’ Dies at 86: Erica Goode:Harold W. Kuhn, an emeritus professor of mathematics at Princeton and a longtime friend and colleague of Dr. Nash’s who died in 2014, said, “I think honestly that there have been really not that many great ideas in the 20th century in economics and maybe, among the top 10, his equilibrium would be among them.” A University of Chicago economist, Roger Myerson, went further, comparing […]

11 Thought-Provoking John Nash Quotes That Are As Offbeat & Wonderful As He Was: Kirsten O’Regan:Many inspiring things have been said about Nash. “This man is a genius,” was the entire contents of a letter to support his application to Princeton’s doctoral program; “Jane Austen wrote six novels, Bach wrote six partitas,” Barry Mazur, a math professor at Harvard, told the Times. “I think Nash’s pure mathematical contributions are on that level.” And Nash, a man with a brilliant […]

John Nash's unique approach produced huge leaps in economics and maths: Alex Bellos:The American mathematician John Nash, who was killed on Saturday night in a car crash, was in Oslo five days ago to receive the Abel prize from the king of Norway. The £500,000 Abel – which he shared with Louis Nirenberg – is considered a kind of maths version of the Nobel prize, which has no category for mathematics.And yet, Nash is also a winner of the Nobel prize, the only person to share both accolades.

Some people are always critical of vague statements. I tend rather to be critical of precise statements; they are the only ones which can correctly be labeled wrong.~ Raymond Smullyan on criticismThe 145th day of the year; 145= 1! + 4! + 5!. There are only four such numbers in base ten. 1, 2 and 145 are three of them, what's the fourth? Such numbers are called factorions, a term created by Cliff Pickover in 1995145 is the result of 34 + 43, making it a Leyland number. a number of the […]

After the Singapore Maths Olympiad birthday problem that went viral, here is a Vietnamese primary school puzzle that made the frontline in The Guardian. The question is: Fill the empty slots with all integers from 1 to 9 for the equality to hold. In other words, find a,b,c,d,e,f,g,h,i such that a+13xb:c+d+12xe–f-11+gxh:i-10=66. With presumably the operation […]

[Intended for a more general audience. Initial draft: comment welcome]Adjusted Winner ProcedureThe Adjusted Winner procedure is a well-known fair division mechanism to settle disputes and divide resource between two parties. It was proposed by political scientist Steven Brams and mathematician Alan Taylor:Since the allocation of resources is typically seen in the context of conflict and cooperation, the parties are referred to as agents  or player as is standard in the field of game […]

As I write, the mathematician Katie Steckles is in residence at the Stephen Lawrence Gallery of the University of Greenwich, where she is demonstrating some fun maths to the public and getting people to take part in various mathematical activities.  It's a fascinating show, covering many different kinds of mathematics, from tessellation to random walks, fractals to Benford's Law, and some graph theory.For me, what has emerged is the visual connections.  My photo above shows to the […]

Before a big celebration, a king receives a delivery of 1,000 kegs of beer. But there is a slight problem: one of the kegs has been poisoned. The bad beer is indistinguishable in every way, except that it causes food poisoning about one hour after ingested. The king is short on time and bodies. The … Continue reading Can You Identify 1 Poisoned Beer Keg From 1,000? Sunday Puzzle
