All sorts of websites

I'm just going to drill through a few links people have sent me, or that I've taken notice of, lately. Hopefully you'll find something of interest!

1) is a teacher located in Singapore and his site has video tutorials (in English) and a forum getting started.

2) Weekly Math Problems from NASA - download free weekly math problems in the setting of space weather... quite interesting! You'll find topics such as radiation dosages at Mars, exposure calculations, background radiation on Earth... would be perfect for science-minded high school students.

3) This one you'll get to laugh at... Newton's laws revisited.

Some examples:
BATH THEOREM: When the body is immersed in water, the telephone rings.

LAW OF THE RESULT: When you try to prove to someone that a machine won’t work, it will!

LAW OF BIOMECHANICS: The severity of the itch is inversely proportional to the reach.

And so on... click on the link to read more.

4) Mathematical Moments - a series of one-page PDF posters or flyers... about the many various ways mathematics is used in modern society.

Teachers especially could use these to promote awareness of use of mathematics. It's just good to know in general how much mathematics is involved in various fields.. these flyers don't get into any deep stuff but are just real short 'snapshots'. Examples include:
Finding Oil
Solving Crimes
Unearthing Power Lines
Targeting Tumors
Beating Traffic

... and so on.
