Today is February 7, 2018, or 2/7/18 in common date notation, so it is also known as "e Day." The first 4 digits of the mathematical constant,e, are 2.718, so just like Pi Day is celebrated on March 14 (3/14) today is the day we recognize another very important number, which is the base of the natural logarithms and is often called "Euler's number." It appears in one of the most beautiful equations in all of mathematics:
This amazing equation has the Euler's number, the base of the complex numbers, i, the number π and the numbers 1, 0 as well as the symbols = and +!
Happy e day!
