Archimedean drive 2b

The green and orange wheels of Archimedean grooves are identical. The green one is input. The pink pin slides in both grooves and in a straight slot of a immobile bar. The slot is on the line connecting axes of the two wheels. Two wheels rotate in the same direction with the same speed, li

Archimedean drive 3a

The green and orange coaxial wheels of Archimedean grooves are identical. The pink pin slides in both grooves and in a straight slot of a fixed bar. The two wheels rotate in opposite directions with the same speed. Pitch of the Archimedean groove must be big enough to prevent possible jam.

Finding Pi by Archimedes' Method

Archimedes approximated the value of Pi by starting with the fact that a regular hexagon inscribed in a unit circle has a perimeter of 6. He then found a method for finding the perimeter of a polygon with twice as many sides. Applying his method repeatedly, he found the perimeter of a 12

Squaring the Circle with the Archimedean Spiral (animated visual proof)

This is a short, animated visual proof that we can square the circle IF we use the Archimedean spiral. Unfortunately, this is not a solution to the squaring the circle problem from antiquity because that requires it to be done with only a straightedge and compass. #mathshorts​ #mathvideo​

Bridgeland stability structure/condition on a triangulated category is a vast generalization of the notion of an ample line bunlde (or polarization) in algebraic geometry. The origin of the notion lies in string theory, and is applicable to derived categories of coherent sheaves, quiver re
