Roulettes (curve)

Hypocycloid

In geometry, a hypocycloid is a special plane curve generated by the trace of a fixed point on a small circle that rolls within a larger circle. As the radius of the larger circle is increased, the hypocycloid becomes more like the cycloid createdby rolling a circle on a line. (Wikipedia).

Hypovolemic shock

In this Surgery Snapshot I discuss hypovolemic shock in surgery. There are two main reasons for a patient to develop hypovolemic shock. The first being hemorrhage and the second being plasma loss. This short lecture contains refernce to the four classes of hemorrhagia.

Epicycloids and Hypocycloids - A Link Between Curve Stitching and the Mandelbrot Set #SoME2

Epicycloids and Hypocycloids appear everywhere in math; especially the cardioid. These shapes act as a fascinating link between curve stitching, and the Mandelbrot set (as well as the Multibrot sets). Below are links to some programs and resources. I encourage anyone to explore and play

Pi is approximately 355/113 (pi day short)

This short animation shows the beginning of the creation of the hypocycloid where the ratio between the radii of the two circles is Pi. Because Pi is irrational, the hypocycloid will never close, so we end after 113 revolutions. As a byproduct, it appears that the curve almost closes up, a

Pi Hypocycloid

This short animation shows the beginning of the creation of the hypocycloid where the ratio between the radii of the two circles is Pi. Because Pi is irrational, the hypocycloid will never close, so we end after about 2 minutes. If you like this video, check out my others and like and sub
