Irrational numbers such as pi or the square root of 2 have always fascinated humankind. For thousands of years, scholars have ...

Fuzzy number approximation techniques aim to represent complex uncertain quantities in a form that is tractable for analysis and computation. Broadly speaking, original fuzzy numbers may be nonlinear ...

The ancient Greeks wondered when “irrational” numbers can be approximated by fractions. By proving the longstanding Duffin-Schaeffer conjecture, two mathematicians have provided a complete answer. The ...

When my students grow too dependent on their calculators, I ask them to find a number that, when multiplied by itself, gives them 2. Students quickly see that since 1² = 1 and 2² = 4, the answer has ...

Earlier this summer, we posted about a study that revealed that monkeys could listen to a series of beeps and then equate it to a visual representation of the same number. One of the researchers ...

The study of natural, social and technological phenomena in complex systems invariably requires approximations that coarse-grain and simplify, so that insights can be obtained about the causal ...
