1. Cookie jars and tessellations
 |
How can we neatly stack cookies into a circular jar? This topic is related to "tessellations". Math is not only about algebra - visual design and packaging also use mathematical techniques. See more in: Cookie jar math |
2. Your heartbeat and Fourier Series
 |
I recently had an ECG done and found it very interesting. This article explains how we can model the human heartbeat with a mathematical expression, using Fourier Series. |
3. IntMath Poll - Math and Real-world Problems
The Feb-Mar 2010 IntMath Poll revealed around 70% of students get little idea why they need to study math during their lessons. The question and responses were:
I get a good understanding of how math is applied to real world problems...
In most lessons: 31%
In some lessons: 29%
Rarely: 24%
Never: 17%
Total votes: 2200
Students need to see how to use math, otherwise it can become a painful academic exercise!
Of course, many of us like math for its own sake, but that's not the feeling of many students.
4. Latest IntMath Poll - Who are you?
A new poll is up and asks readers whether they are students or instructors, or maybe retired people wanting to learn.
You can respond on any page in IntMath.com (look in the right margin when you get there).

7. Final thought – Commitment to excellence
Since this Newsletter has a sports theme, we'll finish with a gem from a famous football coach:
