Euler's constant

Euler's constant (sometimes also called the Euler–Mascheroni constant) is a mathematical constant usually denoted by the lowercase Greek letter gamma (γ). It is defined as the limiting difference between the harmonic series and the natural logarithm, denoted here by Here, represents the floor function. The numerical value of Euler's constant, to 50 decimal places, is: 0.57721566490153286060651209008240243104215933593992... Unsolved problem in mathematics: Is Euler's constant irrational? If so, is it transcendental? (more unsolved problems in mathematics) (Wikipedia).

The Euler Mascheroni Constant

I define one of the most important constants in mathematics, the Euler-Mascheroni constant. It intuitively measures how far off the harmonic series 1 + 1/2 + ... + 1/n is from ln(n). In this video, I show that the constant must exist. It is an open problem to figure out if the constant is

Euler's number, derivatives, and the bank at the end of the universe

Euler's number, e, is defined as a limit. The function e to the x is (up to multiplying by a constant) the only function that is its own derivative. How are these two related? In this video you'll find an explanation for this phenomenon using banking interest rates, and a very particular b

Infinite money hack: Euler’s number and compound interest

Compound interest is a powerful concept that allows individuals to grow their wealth over time. It's based on the idea that the interest earned on an investment can be reinvested to generate even more interest, creating a "snowball" effect that can lead to significant growth. Subscribe: h
