# Letter: Happy birthday to Merkel

German Chancellor Angela Dorothea Merkel entered politics after the Berlin Wall fell in 1989 and has supported science during her eight years as chancellor. She has been widely described as the de facto leader of the European Union, the most powerful woman in the world, and by many commentators as the leader of the Free World.

Born on July 17, she turned 65 last month. She has been experiencing some health issues recently, so I prepared the following numerical birthday curiosities in her honor and to cheer her up:

1. Merkel’s birthdate, 7/17, coincides with the 198th day of each non-leap year (e.g., 2019). Interestingly, twice the sum of the squares of the digits of 17/07 also equals 198.

2. The sum of the letter numbers of Angela Merkel equals 104, the 104th prime number is 569, and 3 times 569 equals 1707, her birthdate.

3. Merkel turns 65 on 17/07/2019 and 66 on 17/07/2020. If 17072020 is split in the middle as 1707 and 2020, these two numbers differ by 313, and 313 is the 65th prime number.

4. Lastly, Merkel’s 70th birthday in 2024 expressed as 7/17/24 will be special since 17 plus 7 equals 24.

Happy 65th birthday, Angela Merkel!
