Have you ever wondered why the number 1 isn’t a prime, even though 1 is the product of 1 and itself? It actually used to be considered prime, but mathematicians redefined prime numbers just to exclude it!

Mathematicians wanted to simplify the Fundamental Theorem of Arithmetic, which states that every positive integer greater than 1 can be written as a unique product of primes. The order of the primes doesn’t matter.

For example, 12=2*2*3, so the unique prime factors of 12 are 2, 2, and 3. If 1 were prime, there would be lots of different ways to write 12 as a product of primes: 12=1*2*2*3, 12=1*1*2*2*3, 12=1*1*1*2*2*3, etc. Not so unique anymore!

Today’s date, 3/20/2023, is a palindrome in m/dd/yyyy format, meaning the numbers can be read in the same order forwards and backwards: 3202023. Today and the next 9 days will also be palindromes in m/dd/yy format!

Katherine Johnson was one of many women working as “computers” during the space race. Even after NASA began using electronic computers, astronaut John Glenn still refused to fly until Johnson verified that she got the same calculations. In 2015, Johnson was awarded the Presidential Medal of Freedom.

Even if you haven’t heard of Dr. Gladys West, she’s had a big impact on the world—and your movement through it! The Earth isn’t a perfect sphere, and Dr. West’s work modeling the variations caused by gravity, tides, and other forces laid the groundwork for GPS and the highly accurate maps we use today.
