The blog carnival website has been unreliable for months now, and it’s high time we came up with another way for you to submit your posts to the Math Teachers at Play blog carnival. So when I saw the snazzy new Carnival of Mathematics submission form, I knew I had to learn to use Google Docs.
In 1905, when he was 26 years old, Albert Einstein rocked the scientific world with a series of papers that changed our understanding of the nature of the universe. At MinutePhysics, the celebration continues:
Someone mentioned one of my old books on the Living Math forum, which made me curious how the used copies were doing at Amazon.com. These are simple little books, 100 loose pages comb-bound together. I have seen ridiculous prices before, but this one takes the cake.
Thankfully, there are a few used book dealers with more sense, or at least with more reasonable computer-automated pricing routines.
I am still at work revising (and greatly expanding) the old books so I can publish new editions. If you haven’t voted yet in my “What Do You Want from a Math Book?” survey, I’d love to hear your opinion!
Ready for math games, great books, tangrams, logic, pi, quadratics, inspiration, and plenty of fun? Check out Bon’s just-posted Math Teachers at Play “Fifteen-Word Sentence Challenge” blog carnival:
Blog Carnival for Math Teachers at Play Number 48 Is Here – With a Fun Twist!
It’s my turn, again, to host the very cool Math Teachers at Play Blog Carnival. Fridays sometimes have a 50 Word Friday article with a special feature – exactly 50 words. I’m doing a variation of this – every sentence in this post has 15 words exactly. The requirement will be hard to meet, but I can do it with some effort! …
Happy Pi Day, from Vi Hart:
Today would be Albert Einstein’s 133rd birthday. At MinutePhysics, the celebration continues:
March 14th is Pi Day, and it’s also Albert Einstein’s birthday. In honor of Einstein, MinutePhysics is posting a series of videos on his “wonder year” of 1905, when he published several papers that eventually earned him the Nobel Prize.
To celebrate their re-release of his classic puzzle books, the Dover Math and Science Newsletter featured an interview with Raymond Smullyan, as well as several extended excerpts from his books. (For my math club students: Professor Smullyan invented the Knights and Knaves puzzles.) Enjoy!
It seems like a corrolary to Murphy’s Law: Whenever I claim that the blog carnival site is working, it immediately goes on the blink. At any rate, I can’t get the site to load at all today. If you want to send in a post for the next math carnival, you can:
Everyone is welcome — if you’ve written a blog post about learning, teaching, or just playing around with math, from preschool to calculus, please send us your link!
The 2012 Purple Comet! Math Meet is a free, on-line, team competition for middle and high school students around the world. Every team needs an adult supervisor. Homeschoolers are welcome and should register under the Mixed Team category.
Register now. The contest will run Tuesday, April 17, through Thursday, April 26, 2012. That gives your team plenty of time for practice sessions between now and then.
