## Mathematicians Of The Day

### 5th March

On this day in 1616, Cardinal Robert Bellarmine, the chief theologian of the Roman Catholic Church, issued a decree which declared Copernicanism false and erroneous. When Galileo subsequently ignored the decree, he was put on trial and held under house arrest for the final eight years of his life.

#### Quotation of the day

##### From Pierre-Simon Laplace

It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit. But its very simplicity and the great ease which it has lent to computations put our arithmetic in the first rank of useful inventions; and we shall appreciate the grandeur of the achievement the more when we remember that it escaped the genius of Archimedes and Apollonius, two of the greatest men produced by antiquity.
