Sound Waves Circular Motion Water Coolness from 9gag

24-Hz sound wave collides with water

Click this link to the 9gag video - very cool


Click the link and watch what sound waves do to water

From the people at 9gag and thanks to Annalis in G09 for sharing it with me.

what is the white rectangle doing there? I don't know - I'll fix that this weekend (:

MYP3 Mathematicians Helping Others Understand Curves

Before I introduce three fabulous websites, I'd like to say that ALL of the MYP3 mathematicians have produced wonderful work demonstrating their understanding of curves and their transformations. Mathsland is proud to call them all citizens.

In our unit we were focusing on linear functions y=mx+p, and dipping into some quadratics but some decided they would like to go further and investigate other curves.

We had linear, quadratic, square root, Archimedes Spiral, sinusoidal and exponential curves. It was busy in Mathsland because everyone had different questions and a different adventure.

Three students, Annalis, Chanya and Eugene (alphabetical order chosen there), created websites using skills taught to them by the much beloved and missed Ajarn Marcus. By creating websites they are providing a service to other learners in the world of mathematics that want to know about sinusoidal waves and exponential functions.

Students used the desmos.com/calculator and its groovy sliders to play around with parameters to spot patterns.
check out some sliders here

Now for the websites:

Annalis' Exponentials are Cool



Eugene's Vas Are Sinusoidal Waves


Chanya's Parabolas

This is HUGE!

Sorry about the lack of posts, I'm planning to make up for it.

And if you find something cool - a video or graphic or story that's mathematical, share it with me and I'll post it (referencing you of course).

It's about our universe, seconds after it began.

It's about theories and persistence

It's about patience and taking the time, a long time...

CHECK IT OUT HERE WOWOWOW

I love science and numbers
