Now that the reader is persuaded, about this strange mathematical connections, we go into some details. All examples thus far we brief, and here we take our time and explain, in some detail, four strange cases where an ancient mathematics resurfaces and shows its face in modern world. Each of these four essays stands alone and can be read independently. They cover: Earths trajectory, music and trigonometry, logic and logic circuits, and erratic path of atoms and stock market. At the end, we summarize our findings and declare that we seem to be none-the-wise. True, we are now even more convinced about this spooky action of mathematics, but have no idea why.
