1st Century in Science
This is a summary of scientific and technological advancements in the 1st Century A.D.
Mathematics
In circa 60 AD, the Hero of Alexandria discovers Heron's Formula, which is used to calculate the area of a triangle where the length of all three sides are known.[1]
Around 100 AD, Menelaus of Alexandria describes spherical triangles, laying the groundwork for Non-Euclidean geometry.
Technology
The Hero of Alexandria invents the aeolipile, also known as the Hero's Engine, which is considered to be the first steam engine. The engine spins when the central ball is filled with heated water, which produces torque.[2]
