## 1. Google International Science Fair

Google is holding an International Science Fair. This can involve math, too, especially in the data collection and processing parts!

There are good prizes involved (a $50,000 scholarship for the winner, and$25,000 each for the 2 runners-up). As Google says:

Google is looking for the brightest young scientists from around the world to submit interesting, creative projects that are relevant to the world today.

Note: The competition closes 1st April 2012. It's for 13 to 18 year-olds (any country) and you can submit as an individual or in a small group.

Here's a video of last year's impressive winners: Award winning teenage science in action.

I encourage you to give this a go. It's a good chance to do something meaningful and learn a lot.

## 2. "e" Day next week (Feb 7th)

 The number "e" crops up in many areas of mathematics, and has many real-life applications. This article gives some background about "e". You'll also learn about infinite sums. "e" day (Feb 7th)

## 3. The Versa Ruler

The inventor of a new kind of geometry ruler wrote to me recently to tell me about a new ruler he invented.

My first reaction was to wonder why we'd want such a thing in this age of computers, where constructing angles, parallel lines and trapezoids is trivial if we use software like GeoGebra.

Anyway, this is what he had to say:

My invention is the Versa Ruler, the world’s first shape-making ruler. It’s a connectable system of rulers and protractors capable of forming and locking an unlimited number of 2-D rectilinear shapes. Please take a look at our video, and I would welcome any comments.

Here's a short video about it: Video: Shape-making Versa Ruler

He anticipated my thoughts about computer-based solutions with this:

With so many of our tactile experiences going digital, our mission is to nurture both creativity and productivity at a visceral level. And as our education becomes more visual, the honing of our aesthetic senses will play an increasingly vital role in how well we learn.

What do you think? Would this ruler be useful for you in your math classes? Please respond in the comments.

## 4. Answerify - a new forum

Update: This site no longer works properly. I have removed the links from this section.

There are many forums for getting math help, and I summarized them earlier in Top 10 Math Help Sites.

Here's a new one, Answerify where you can "get answers to all your questions on problems in mathematics along with facts and information about various science subjects".

It's free to join. Probably one of the best opportunities with such forums is in answering others' questions. Remember, "to teach is to learn twice".

## 5. Autograph 2-D and 3-D graph plotter: a review

 Autograph is a well-designed 2-D and 3-D plotting application for education. Here's my review. Autograph 2-D and 3-D graph plotter: a review

## 6. Friday math movies

 (a) Spirals, Fibonacci, and Being a Plant Vi Hart presents an enthusiastic rendering of spirals and Fibonacci, as relating to plants. Friday math movie: Spirals, Fibonacci, and Being a Plant
 (b) Carlo Ratti: Architecture that senses and responds This video shows how we can improve our lives using sensing data. Friday math movie: Carlo Ratti Architecture that senses and responds

## 7. Final thought - make it creative

Often, math class is boring because it lacks creativity. John Updike, 20th century novelist and short story writer, had this to say about how seemingly mundane tasks can be made more creative:

An activity becomes creative when the doer cares about doing it right, or better. [John Updike]

There is planty of scope for making math more creative. Start with the many connections with art, music and sports, and aim to do it better!

Until next time, enjoy whatever you learn.

I am a new member. As a retired Aerospace Eng, I have interest in math and stay in close touch with students by tutoring in a local Junior Colleges. The internet has several weekly math problems designed for several different skill levels. I followed one title "Problem of the Week" for several years. Does IntMath support any such on-line math activity? I found this to be both, fun and a way to keep my problem solving skills in tune. Also, when several individuals have similiar math background, it is great to share interesting problems. Don Miller

2. Murray says:

@Don: Good to hear from you. Yes, the IntMath Newsletter has such a problem from time to time. I will need to reinstate it soon. Thanks for the nudge!

Hello Sir,
i have not been in touch with you for ages-----will mend my ways in 2012.

This bit is good : " ---Often, math class is boring because it lacks creativity. John Updike, 20th century novelist and short story writer, had this to say about how seemingly mundane tasks can be made more creative:

When one teaches Calculus to the higher secondary school level pupils , their motivation is ,generally , high.
The problem is to turn their vision from the idea of * just
doing well in the Final Exams.* to taking interest in the mathematical background of Calculus as an intellectual advance of all mankind.
Any one can pass * examinations* ; what distillate one takes beyond the examination is mathematical CULTURE !!

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 mix both types of math entry in your comment.
