1. Latest feedback on IntMath <\/h2>\n

(a) IntMath was named an "excellent Twitterer" in the BestNursing.net article \"50 Excellent Twitterers Providing Daily Learning & Study Tips\". [no longer available.] <\/p>\n

You can follow Intmath on Twitter<\/a>. <\/p>\n

(b) Reader J. Venkata Ramana (from India) enthusiastically wrote this about IntMath.com: <\/p>\n

\n

O! Great Guruji! I bow to you. A very astonishing, surprising way of teaching Mathematics with ease. <\/p>\n

When one visits your site the content gets recorded in the mind. They cannot forget. This is a great job!<\/p>\n<\/blockquote>\n

("Guruji" means "revered teacher". I'm blushing...) <\/p>\n

It's always nice to hear how IntMath helps people. <\/p>\n

2. Resource - free online math calculators <\/h2>\n

Here is an interesting collection of free calculators. You can choose from 18 different calculators, including ones that draw graphs, some that help with algebra and there's even a fraction calculator.<\/p>\n

When you get there, you can choose the different calculators using tabs at the top of the page that look like this:<\/p>\n

\"calculators\"<\/a> <\/p>\n

Here's the link: Online math calculators<\/a> <\/p>\n

3. Math tip: Summation <\/h2>\n

Suitable for: <\/strong>Everyone! You will all come across summation notation at some stage. <\/p>\n\n\n
\n

\"Summation\"<\/a><\/p>\n<\/td>\n

In this dialog, Yousuf has trouble understanding a question involving summation notation. After some effort, he gets there!<\/p>\n

This is quite a long post, but it is worth following it all the way through.<\/p>\n

3. Riemann Sums <\/h2>\n

Suitable for: <\/strong>This article introduces some important concepts in calculus. Even if you are not at that level yet, you will still get something from playing around with the graphs. <\/p>\n\n\n
\"Riemann<\/a><\/td>\n\n

In this article, you can investigate the area under a curve<\/strong> using an interactive graph. This demonstrates Riemann Sums.<\/p>\n

Mathematicians worked very hard to crack this problem, starting with the ancient Greeks and culminating in the work of Newton and Leibniz in the late 17th century. <\/p>\n

4. Friday math movie - Martin Gardner <\/h2>\n

Suitable for: <\/strong>Everyone.<\/p>\n\n\n
\"Martin<\/a><\/td>\n\n

Martin Gardner, who wrote widely on recreational mathematics for Scientific American<\/em> magazine, died in May 2010. Here is an interesting one-hour TV special that features Gardner.<\/p>\n

Watch the video: <\/p>\n

5. 2010 Census <\/h2>\n

Suitable for: <\/strong>Everyone.<\/p>\n\n\n
\"bureau<\/a><\/td>\n\n

The census is going on right now in the US, and in Singapore too. <\/p>\n

So you think counting is simple? Whenever there is statistics about people, it is never straightforward.<\/p>\n

The decennial (once every 10 years) Census gives an interesting snapshot on population and culture throughout time. The questions continually evolve and that’s what makes it interesting. <\/p>\n

6. Final thought \u2013 looking for new skills <\/h2>\n

Author, keynote lecturer and productivity consultant Denis Waitley has the following to say about learning, and it is quite relevant during the long summer holiday months: <\/p>\n

\n

All of the top achievers I know are life-long learners, looking for new skills, insights, and ideas. If they're not learning, they're not growing, and not moving toward excellence. <\/p>\n<\/blockquote>\n

Denis Waitley <\/p>\n

Since it is now the summer holidays in most of the Northern hemisphere, you may be interested to read an article I wrote a few summers ago, The Summer Math Brain Drain<\/a>. How will you spend your summer?<\/p>\n

Until next time, enjoy whatever you learn. <\/p>\n
