Sound Math 1: Good Vibrations!

May 1, 2019

There is so much maths around sound, but sound is simple.

Sound is made by something vibrating in air. The vibrations create waves and these pressure waves hit your ear.

Projects Studio Handbook HARMONICS

This is a vibration plate. Sand collects in the areas which do not vibrate and create patterns. The patterns are called CHLADNI figures.

In fact, the sand collects in places where standing waves – waves that cancel each other out – form. The rest of the plate is vibrating and making the sound.

You will find more info about this violin shaped vibration plate here.

The frequency of the sound creating this Chladni pattern is shown in Hertz Hz (no. pressure waves per second that his your ear) is shown  for each pattern. (More about frequency in following posts)

Giant Easter Egg Maths … METRIC

April 5, 2019

Good News for Chocoholics

To get the right texture Easter Eggs are made from sugar or sucrose and not from corn syrup. But chocolate contains lots and lots of sugar.

This egg is 10.39 m high and weighs 7,200 kg , but  it is ugly. I like the GUYLIAN GIANT EGG (below) because it looks good and we also know how much sugar is in the egg.
