New Math = Trouble?
About.com Mathematics10 Feb 2013 | 4:20 amThese battles have been raging on for many years and I'm old enough to know that I was taught the old math. For me, old math meant no technology or math manipulatives. Back then, calculators were adding machines and only the business classes used those. Math for me was computations with a few word problems thrown in for good measure. I didn't have access to math manipulatives and had a math textbook for each grade. As time went on, I did, however, embrace manipulatives and strove to teach for understanding....Read Full Post -
Grimm's Fairy Tale Metrics
Neoformix31 Jan 2013 | 8:05 amI have built another little digital humanities project based on the text of the 62 stories in Grimm's Fairy Tales. This one is called Grimm's Story Metrics and presents an interactive matrix of stories together with various metrics calculated from their text. You can click on a column to sort by that data, click again to reverse the direction, and click on a story name to open it in another window. The image below shows the stories sorted by the 'Royalty' metric which indicates, as you would expect, how many references there are to words related to the topic of royalty. Click on the image to… -
A pastor, a doctor and a mathematician
Natural BlogarithmsSplineGuy18 Nov 2012 | 10:08 pmA pastor, a doctor, and a mathematician were stuck behind a slow foursome while playing golf. The greenskeeper noticed their frustration and explained to them, “The slow group ahead of you is a bunch of blind firemen. They lost their sight saving our clubhouse from a fire last year, so we always let them play for free.” The pastor responded, “That’s terrible! I’ll say a prayer for them.” The doctor said, “I’ll contact my ophthalmologist friends and see if there isn’t something that can be done for them.” And the mathematician asked, “Why can’t these guys play at… -

Broken Clock Puzzle
CSE Blog - quant, math, computer science puzzlesPratik Poddar4 Feb 2013 | 11:58 pmSource: www.ocf.berkeley.edu/~wwu/riddles/medium.shtml Problem: My fancy new digital alarm clock is broken! The time 'jumps' around. When I reset it, it reads 12:00:00. Then it runs as it should, but after 12:04:15 it resets back to 12:00:00. It counts up to 12:04:15 again and then it jumps to ... 12:08:32 ! Weird stuff. Do you know what's wrong with my alarm clock? Update (12/02/2013) Solution posted by Saumya Gupta, Abhimanyu Dhamija (CSE IITB 2011 Alumnus, Citibank Analyst) and Naga Vamsi Krishna in comments!

Dave Richeson – Inspired by Math #20
Sol8 Feb 2013 | 2:47 pmProfessor Dave Richeson is one of the most exuberant math people I've gotten to know but I didn't know how exuberant he was until I interviewed him. He's also involved in a bunch of neat projects. It was one of these projects, documented in Dave Richeson's blog article, How I teach topology: an inquiry-based learning approach, that caught my attention since I have a real passion for collaborative learning.

There's a strong focus on the historical setting for these explorations. This setting brings the mathematics to life. I was very impressed to learn how very smart ancient astronomers and mathematicians were. Our twentyfirst century perception that we are smarter than…

End of Year Suggestion: Steve on Counting
Loren Shure27 Dec 2012 | 10:15 amI just read the latest post on Steve Eddins image processing blog. I recommend you read it too. It discusses how to count objects in an image without introducing bias. It would be easy to count all the blobs you see, including partial ones cut by the border. But that would be an overestimate. So how do we get a better estimate?ContentsCounting Via Each "Lower Right Corner"Weighted Count of Interior ObjectsCounting Via Each "Lower Right Corner"The first technique Steve discusses is one I am familiar with already. The basic idea is to count all objects that don't touch any edges of the image,… -

Geometric art project: seven-circle flower design
4 Feb 2013 | 12:19 pmI got inspired by the blogpost Art School | Geometric Design with Islamic Art where Deborah shows how to make a neat flower design with seven circles, using a compass, and then coloring it using 2, 3, or 4 colors (or however many of your own). I think it ties in neatly with mathematics, and lets students practice drawing circles with a compass. My girls loved the art/math project. Here are pictures they made:Here are step-by-step instructions for the flower design:1. Draw a line and a circle so that the circle's center point is on the line. Then mark the points where this circle… -
Möbius Strip
3 Feb 2013 | 10:18 amMöbius strip is a fun object to play with. The video below by Vi Hart has a little story to go with the idea: Wind and Mr. Ug.

See if you can solve the mystery... While they were watching, I made my girls some Möbius strips and let them draw a line or a "fence" around them. I cut one apart in the middle to show what happens when an "earthquake" hits... Like I said, simple and fun.I found the video via this… -
