A quotation for today

Lewis Richardson (1881 - 1953)

Big[ger] whirls have little whirls,
That feed on their velocity;
And little whirls have lesser whirls,
And so on to viscosity.

[summarising his paper The supply of energy from and to Atmospheric Eddies 1920]

Another quotation by one of today's mathematicians
