1. Resource: Math, physics and engineering applets <\/h2>\n

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

Here is an extensive range of interesting interactive java applets, including investigations into waves and acoustics (by Paul Falstad). <\/p>\n

Math, physics and engineering applets<\/a><\/p>\n

The page has links to other great interactive resources, including one of my favorites:<\/p>\n

Secret Worlds: The Universe Within<\/a>, which allows you to zoom in step-by-step from the outer universe right into the nucleus of an atom. <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

2. Use it or lose it <\/h2>\n

3. Math tip: Integration by parts twice<\/h2>\n

Suitable for: <\/strong>Those who are currently studying about integration, a key topic in calculus.<\/p>\n\n\n\n
\"integration<\/a><\/td>\n\n

Sometimes integration by parts can end up in an infinite loop. But there is a solution. And a reader suggests an even better approach. <\/p>\n

\"fractal<\/a><\/td>\n\n

(a) Fractals without a computer<\/h4>\n

You don't need a computer program to produce fractals. It can all be done with mirrors!<\/p>\n

6. Latest Feedback on IntMath <\/h2>\n

Here is some feedback on IntMath.com<\/a> I received recently from Jeremy Springston:<\/p>\n

\n

I'm sure you guys hear this often, but this site is absolutely amazing. I'm active duty Navy and have been in Afghanistan for a while now and, thanks in part to your site, teaching myself Calculus has become bearable.  When I get stuck somewhere, I know your website will have the "key" to my problem.  I made an A in my Pre-calc class, and am currently making an A in Calc I and, the best part, I fully understand what I've learned!  Again, I'm deeply thankful for all your efforts and keep up the fantastic work. <\/p>\n<\/blockquote>\n

Thanks, Jeremy! I'm glad you found the site useful and it helped in your success.<\/p>\n

Please help keep IntMath free - recommend it to your friends! <\/p>\n

7. Final thought \u2013 never too old to learn<\/h2>\n

Continuing the theme of lifetime learning, here is a quote from the founder of the Ford motor company. <\/p>\n

\n

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.<\/p>\n<\/blockquote>\n

Henry Ford <\/p>\n

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