Physicist reckons two-button calculator can do all elementary math

Andrzej Odrzywołek, a postdoctoral researcher at Jagiellonian University, proposes in a preprint paper that a single mathematical operator—eml(x,y) = exp(x) - ln(y)—can generate all elementary mathematical functions, including trigonometry, algebra, and arithmetic operations. The work claims an analogy to Boolean logic: just as a single gate suffices for all digital operations, continuous mathematics may have a fundamental primitive. A theoretical two-button calculator (EML and digit 1) could compute everything a full scientific calculator performs.
