Steve Mould, a mathematician, shows how cool it is to mic creativity with science. This phenomenal science experiment will leave you astounded. He spread couscous on a table and then used a rod to make these pretty patterns. And, moreover it is all mathematics.
To plot the random distribution of Couscous. Spread Couscous on the table.
And play the table like a musical instrument. You get a pattern appearing on the table.
These figures were explained first by Ernst Florens Friedrich Chladni, who was a German physicist and musician. Although he was unable to explain the 'how' behind it. So, most of the work for explaining this was done by Sophie German.
She wasn't, till she lived, given any recognition for her work in explaining the chladni figures' mathematics.
The equations describing the problem.
By scattering them.
And do it yourself. Mathematics just got interesting!
