  Definition: Proofiness is defined as "the art of using bogus mathematical arguments to prove something that you know in your heart is true — even when it's not." -Charles Seife

• The Almgren "Mayday" Race is an annual relay race between Princeton and Rutgers.
  The next race will be on May 5, 2024, from Princeton to Rutgers. It will be the 48th annual race between the Princeton and Rutgers Mathematics Departments.

Fun Facts about Mersenne primes: In 1644, a French monk named Marin Mersenne studied numbers of the form N=2^p-1 where p is prime, and published a list of 11 such numbers he claimed were prime numbers (he got two wrong). Such prime numbers are called Mersenne primes in his honor. The first few Mersenne primes are 3,7,31,127 (corresponding to p=2,3,5,7), The next few Mersenne primes are 8191, 131071, 524287 (for p=13,17,19). (Each prime N=2^p-1 has p log₁₀(2) digits.)
Not all numbers of the form 2^p-1 are prime; Regius discovered in 1536 that p=11 gives the non-prime 2047=23*89. The next few primes p for which 2^p-1 is not prime are p=23 and p=37 (both discovered by Fermat in 1640), and p=29 (discovered by Euler in 1738).

Mersenne primes are the largest primes we know.
The largest known prime is the 52nd Mersenne prime, with p=136279841; it has over 41 million digits, an was disdcovered by a former NVIDIA employee in 2024. The next largest known prime is the 50th Mersenne prime, with p=82,589,933; it has over 24 million digits and was discovered by an IT professional in December 2018. The 50th Mersenne prime was discovered in December 2017 using a Tennessee church computer; it has 23 million digits and p=77,232,917. Other recently discovered Mersenne primes are the 49th (2016) with 22 million digits and p=74,207,281; the 48th (2013) with 17 million digits and p=57,885,161; and the 47th, which has 13 million digits and p=43,112,609.

For years, the Electronic Frontier Foundation (EFF) offered a $50,000 prize for the first known prime with over 10 million digits; the 44th had 9.8 million digits and p=32,582,657. The race to win this prize came down the wire in Summer 2008, as the 45th and 46th known Mersenne primes were discovered in within 2 weeks of each other by the UCLA Math Department (who won the prize) and an Electrical Engineer in Germany, respectively. (The 46th had p=42,643,801 and the 45th has p=37,156,667.)
