1. Summer math brain drain

It's summer holidays in the northern hemisphere and sadly, many students get as far away from math as possible. This is a shame because their grade level drops significantly as a result - and math is even harder when school starts again. "Use it or lose it" is certainly relevant here.

Here are some thoughts on this issue, from the archive:

3. Poll results and new poll

Thanks to all who voted in the poll about stress. Here are the results.

Which of these stresses you the most?

Doing exams: 41%

Homework: 24%

Relationships: 18%

Being bullied: 9%

Teachers: 7%

Total votes: 3600

As the poll was conducted during exam time (for those in the northern hemisphere), it's not surprising "doing exams" was at the top. It's encouraging for teachers that they cause least stress out of this list!

Current poll: Your favorite subject?

There's a new poll which asks about your favorite subject at school. Vote on any page in

4. Visual design for math teachers

Suitable for: Teachers, but worthwhile for all of you. It's important to think about how to improve visual communication, especially when it comes to statistics.

This is an important 21st century skill.

Designing better visuals for math class

Diagrams should make things easier to understand, but often they don't. How can we fix this?

5. Friday math movies

Suitable for: Everyone

(a) Artfully visualizing our humanity

(b) Bach Crab Canon

Bach's Crab Canon

Here's a very neat way to illustrate Bach's Crab Canon - using a Mobius strip.

(c) World Metrology Day 2011


This video commemorates World Metrology Day, which was held on 20th May. Go metric and make your lives simpler!

7. Final thought – ambitions

Math anxiety is often the result of criticism by peers. Here is some good advice for such situations from Mark Twain.

Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great. [Mark Twain]

Until next time, enjoy whatever you learn.

    @Dusan: Do you mean the JSXGraph plotter? I only wrote the front end - I've given credit to the developers of JSXGraph and mathjs.js at the bottom of the plotter page.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can't mix both types of math entry in your comment.
