1. Blaise Pascal “We are usually convinced more easily by reasons we have found ourselves than by those which have occurred to others. Pensées “(1670) “Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed.”

2. 11 1 Pascal's Triangle 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1 1 6 15 20 15 6 1

3. 11 1 Zeroth Row  1st Row  1 2 1 2nd Row  1 3 3 1 3rd Row  1 4 6 4 1 4th Row  1 5 10 10 5 1 1 6 15 20 15 6 1

10. Other Interesting Patterns Pascal’s Flowers The gray cell is surrounded by 6 “petals.” If you multiply the yellow petals you get 2100. If you multiply the orange petals, you get 2100.
