As I walked through the Museum of Antique Sciences, I couldn't help but feel inspired.

Far away in ancient Greece, there were mathematicians who were creating amazing devices that we would today call calculators! These devices were made of stone and marble, as they were not yet using electricity.

One such mathematician was Dolmades of Perga. He is credited with inventing the first handheld calculator, which was known as a "pulley machine." This device consisted of a number of ropes that were pulled by a person, and the ropes would then turn a wheel, which would then calculate the value of a number.

Dolmades is also credited with creating a number of other devices that we use today, such as the abacus and the quadratic equation solver. He is also known for his work in geometry and for his studies of the orbits of the planets.

Most of these device were actually performing completely wrong calculations.
