Implications of Gödel’s incompleteness theorem
In the early 20th century, the foundations of mathematics and logic were undergoing significant transformations. Mathematicians sought to establish a comprehensive and consistent framework for all mathematical truths, a goal inspired by David Hilbert’s program to formalize mathematics. However, in 1931, Austrian logician Kurt Gödel revolutionized the field with his Incompleteness Theorems, which demonstrated that…

Derivation of Euler’s formula for imaginary numbers
The Euler formula, one of the most remarkable equations in mathematics, elegantly connects complex analysis, trigonometry, and exponential functions. It is named after the Swiss mathematician Leonhard Euler, who first introduced it in the 18th century. The formula is expressed as: $$e^{ix} = \cos{x} + i\sin{x}$$ Where: e is the base of the natural logarithm,…
