## Celebrating Einstein’s birthday on Pi Day

Besides today being World Kidney Day, which I incorrectly listed on the blog for yesterday, the 14th of March is also the celebration of ** Pi Day**, commemorating the mathematical constant π (pi), which, to two decimal points, equals 3.14.

OK, we’ve already celebrated Pi Approximation Day on the 22nd of July (22/7 is also used to approximate π), but surely this amazing number deserves another mention.

So bake yourself 3.14 pies and share in the celebrations!

Making today extra special, we also celebrate the ** birthday of Albert Einstein** (14 March 1879 – 18 April 1955), the greatest scientist of the 20th century. What makes Einstein such an endearing figure is that, besides his numerous groundbreaking contributions to science (thermodynamics, relativity, quantum theory, wave-particle duality, statistics, cosmology, nuclear physics and much more), he has also made deeply profound contributions to secular subjects as diverse as war and peace, religion, human rights, economics and government.

Many volumes have been written about the great man, so rather than trying (and no doubt failing) to adequately capture his contributions in a single blog post, I will rather leave you with one of his many, many wonderful quotes:

*“Learn from yesterday, live for today, hope for tomorrow.
The important thing is not to stop questioning.”*
