Physicist reckons two-button calculator can do all elementary math

Physicist Andrzej Odrzywołek claims he developed a two-button calculator using only an "exponential-minus-log" function and the digit 1 that can perform all elementary mathematical operations typically requiring a scientific calculator. His unpeer-reviewed research suggests this single operator can generate trigonometric functions, algebraic operations, arithmetic, and mathematical constants like π and e through repeated button presses. While some researchers debate the validity of his approach, Odrzywołek argues this simplification could revolutionize mathematical computing by creating uniform circuits similar to electronic transistors.
