The number e is a #mathematicalConstant approximately equal to 2.71828 that is the #base of the #naturalLogarithm and #exponentialFunction. It is sometimes called Euler's number, after the Swiss mathematician #LeonhardEuler, though this can invite confusion with #EulerNumbers, or with #EulersConstant, a different constant typically denoted γ {\displaystyle \gamma } . Alternatively, e can be called Napier's constant after #JohnNapier.

Oh, look! Another ✨riveting✨ blog post about a topic as dry as toast: estimating logarithms. Because who wouldn't want to read a 5-minute love letter to John Napier's brainchild from the 1600s? 📚🔥 Spoiler alert: count digits, feel smart. 😂

Why You Can't Bring Checkerboards to Math Exams
[A Chess Board Abacus is a Binary Calculator]

@WrathofMath _ https://youtu.be/_Qe_0aj4eEM
"A chessboard and a set of counters makes a formidable calculation device. This is from the final part of John Napier's treatise called Rabdologia, or Rabdology. He called it 'Location Arithmetic as Performed on a Chessboard'. This method of using counters on a chessboard is based on binary and basic algebraic properties, and with only sliding counters on a chessboard we can perform multiplication, division, and square roots, even square roots of irrationals. #maths #mathtricks #mathematics"

After being offline for years, the play transcript of the ClubFloyd folks playing through my interactive fiction / text adventure game Napier’s Cache is back online. I loved seeing how the players tackled my game. This game was inspired by a true story in my family history, involving mathematician John Napier. It was so much fun to write. https://www.allthingsjacq.com/intfic_clubfloyd_20200401.html #interactiveFiction #textAdventure #historicalFiction #IndieGames #ScottishHistory #16thCentury #Mathematics #Occult #JohnNapier
