Meet The Class Of 2014 (MacArthur Fellows): Jacob Lurie: MacArthur Foundation:
Lurie embraces an extraordinary breadth of vision—rewriting large swathes of mathematics from a new point of view—while also working to apply his foundational ideas to prove important new theorems in other areas. With an entire generation of young theorists currently being trained on Lurie’s new foundations, his greatest impact is yet to come.

Lisez Euler, lisez Euler, c'est notre maître à tous.(Read Euler, read Euler, he is our master in everything.)—~Pierre-Simon LaplaceThe 261st day of the year; 261 is the number of possible unfolded tesseract patterns. (I just learned recently that Charles Howard Hinton coined the term tesseract (4-dimensional "cube"). He is also the inventor of the baseball pitching gun.) (see Baseball and the Fourth Dimension) EVENTS1820 André Marie AMPÈRE describes electromagnetic […]

"Rock Breaks Scissors" by William Poundstone
I keep seeing William Poundstone's latest book, "Rock Breaks Scissors"
in the 'business' sections of bookstores… which I think is ashamed,
because a lot of readers who would enjoy it may miss it there. More
appropriately, and like most Poundstone books, it should be in a
science/math area, or perhaps under psychology. Poundstone is one of my

Algebra students have been solving multi-step equations. Quite a great, semi-sneaky way to review all sorts of topics students should already be “fluent” in – operations with rational numbers, the concept of “isolating the variable”, properties of equality, and so … Continue reading →

Sea Urchin-Inspired House Captures Tidal Energy
If you’ve ever dreamed of having a seafront home shaped like a sea urchin — who hasn’t? — then hold onto your swim fins.
The Hydroelectric Tidal House, envisioned by architectural designer Margot Krasojević, draws inspiration from some of nature’s weirdest sea creatures — echinoderms like starfish and sea urchins whose symmetrical shapes have long fascinated biologists. Learn more

Given and , in this note, we are interested in construction of non-radial solutions for the following Lichnerowicz type equation in the whole space . The construction is basically due to Louis Dupaigne and mainly depends on the unique radial solution of the following equation Clearly, this equation comes from the Lichnerowicz type equation by […]

Toronto schools scoring higher in reading and writing, but falter in math: Caroline Alphonso and Kate Hammer:
Math has emerged as a challenge for Canadian educators as international standardized test scores have been steadily falling in every province except Quebec. Parents have been appealing to the ministries of education to take a back-to-basics approach to teaching math, emphasizing repetition and drills over problem solving. Alberta has been the only province to bend to pressure from

“Make the problem about mobile phones. Kids love mobile phones.” I’ve heard dozens of variations on that recommendation in my task design workshops. I heard it at Twitter Math Camp last month. That statement measures tasks along one axis only: the realness of the world of the problem. But teachers report time and again that […]
