1. I must say this is quite brilliant. People have been trying to reinvent the wheel for many years and now finally someone has done it. This is monumental, does anyone know how I could contact the Inventor.

• A sine wave is not a circle, rather it looks like the motion a snake makes when slithering thru the desert.

• A “sine wave” is specifically what you get when you plot y=sin(x) in a cartesian coordinate system, and is not in any way circular.

• ‘representing’ may be the wrong word for a circle, but it represents an oscillation which can include the turning of a circle.

• Certainly – there are neat connections between circles, triangles, and the trigonometric functions. :)

• It’s true that circular motion, when evaluated along a single axis of its plane of motion, can be described as an oscillation, or a sine wave with respect to time. Wow, you were right about something. However I must regretfully inform you that that does not make a sine “wave” a circle in any way, at all, ever, period. Given the context of the article I’m not sure how you were able to believe that saying “but a sine wave is a circle…” was somehow smart. Fascinating.
