1. Modeling fish stocks <\/h2>\n\n\n\n
\"Atlantic<\/a><\/td>\n\n

How can we use math to save collapsing fish stocks? Mathematical modeling is the key. This is an important real-life application of math.<\/p>\n

2. National Geographic - memory game and brain interactive <\/h2>\n

I came across these on the National Geographic site recently.<\/p>\n

Memory game<\/a> (this is an interesting twist on the normal memory games you've played before) <\/p>\n

Brain interactive<\/a> (this allows you to see what happens in the brain when we form memories)<\/p>\n

3. Scope of the IntMath Newsletter <\/h2>\n

When people subscribe to the IntMath Newlsetter, they can indicate topics they would like me to cover.<\/p>\n

I now have (literally) thousands of topic requests, and it would take several lifetimes to get through them all! Of course, I choose the topics which are most often requested. <\/p>\n

The scope of topics in the Newsletter will generally follow the scope of the IntMath.com site<\/a>. That is, basic number and algebra, through matrices, logarithms, trigonometry, to calculus (including Fourier Series and Laplace Transform). <\/p>\n

That's already a very broad scope! <\/p>\n

4. Math puzzles<\/h2>\n

The answer to the math puzzle in the last Newsletter<\/a> was 2πr<\/em>.<\/span> The best answers were by Sheldon<\/strong>, Guido<\/strong> and Tomas<\/strong>, because they showed reasons for their correct answers. <\/p>\n

Latest puzzle:<\/strong> We are designing an East-West roadway which has a curve consisting of the arcs of 2 identical circles as shown. The straight portions are 900 m apart, and the width of the curved portion is 1200 m. The straight portions of road are tangent to the circles, and the arcs themselves have a common tangent where they meet.<\/p>\n

\"Roadway\"<\/p>\n

What is the radius of the 2 circles?<\/p>\n

You can reply here in the comments<\/a>.<\/p>\n

6. Friday math movie <\/h2>\n\n\n\n
\"Religions<\/a><\/td>\n\n

Hans Rosling on Religions and babies <\/strong><\/p>\n

Does religion have an impact on human fertility? Hans Rosling always gives an energetic and thought-provoking presentation. <\/p>\n

7. Final thought - Try! <\/h2>\n

Many math students give up because they feel it's all too hard. This is a shame, because often it only takes a little bit of reading, or trying a few easier problems, or thinking about the big picture and then insight can occur. (I love those \"ahhh - got it!\" moments.)<\/p>\n

Ralph Waldo Emerson, American writer and lecturer, influenced later ideals of freedom and individualization in the US. He could have been talking to math students when he wrote: <\/p>\n

Neither you nor the world knows what you can do until you have tried. [Ralph Waldo Emerson]<\/p>\n<\/blockquote>\n

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