Those interested in category theory might consider joining the summer study group at http://cat.boffosocko.com.

I attended math classes for elementary school teacher training. Most of the teachers in training were mathephobic. I do art and math with origami.

How can whipping up a hollandaise sauce help you understand number theory? Mathematician Eugenia Cheng says that “math, like recipes, has both ingredients and method.” In her new book, How to Bake Pi, Cheng cooks up digestible math lessons on everything from number theory to topology to category theory.

#ExplainTheSun  - The Largest Migration on The Planet

Once, there was the ordinary incandescent light bulb. It shone brightly, but wasted much of the energy put into it as heat. Then came the compact fluorescent. And as costs have dropped, consumers have increasingly been switching to light-emitting diode (LED) technology for many lighting applications, in an ongoing search for a more efficient bulb. Now, in work published in the journal Nature Nanotechnology, researchers report that nanophotonic devices may be able to breathe new life into old incandescent technology. Marin Soljačić and Ognjen Ilic, two authors of the study, explain how they’ve been able to “recycle” some of the incandescent bulb’s wasted heat and re-emit it as visible light, boosting efficiency.
