Australia
Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands.
See Harmonograph and Australia
Canberra
Canberra is the capital city of Australia.
Double pendulum
In physics and mathematics, in the area of dynamical systems, a double pendulum also known as a chaotic pendulum is a pendulum with another pendulum attached to its end, forming a simple physical system that exhibits rich dynamic behavior with a strong sensitivity to initial conditions. Harmonograph and double pendulum are pendulums.
See Harmonograph and Double pendulum
Ellipse
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.
Francis Sears
Francis Weston Sears (October 1, 1898 – November 12, 1975) was an American physicist.
See Harmonograph and Francis Sears
Frequency
Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time.
See Harmonograph and Frequency
Gimbal
A gimbal is a pivoted support that permits rotation of an object about an axis.
Hugh Blackburn
Bailie Hugh Blackburn (2 July 1823 – 9 October 1909) was a Scottish mathematician.
See Harmonograph and Hugh Blackburn
Lissajous curve
A Lissajous curve, also known as Lissajous figure or Bowditch curve, is the graph of a system of parametric equations which describe the superposition of two perpendicular oscillations in x and y directions of different angular frequency (a and b). The resulting family of curves was investigated by Nathaniel Bowditch in 1815, and later in more detail in 1857 by Jules Antoine Lissajous (for whom it has been named).

Mathematics
Mathematics is a field of study that discovers and organizes abstract objects, methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself.
See Harmonograph and Mathematics
Pantograph
A pantograph (from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen.
See Harmonograph and Pantograph
Pen
A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing.
Pendulum
A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. Harmonograph and pendulum are pendulums.
Perpendicular
In geometry, two geometric objects are perpendicular if their intersection forms right angles (angles that are 90 degrees or π/2 radians wide) at the point of intersection called a foot.
See Harmonograph and Perpendicular
Questacon
Questacon – The National Science and Technology Centre is an interactive science communication facility in Canberra, Australia.
See Harmonograph and Questacon
Simple harmonic motion
In mechanics and physics, simple harmonic motion (sometimes abbreviated) is a special type of periodic motion an object experiences by means of a restoring force whose magnitude is directly proportional to the distance of the object from an equilibrium position and acts towards the equilibrium position. Harmonograph and simple harmonic motion are pendulums.
See Harmonograph and Simple harmonic motion
Spiral
In mathematics, a spiral is a curve which emanates from a point, moving farther away as it revolves around the point.
Spirograph
Spirograph is a geometric drawing device that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids. Harmonograph and Spirograph are curves.
See Harmonograph and Spirograph
University of Glasgow
The University of Glasgow (abbreviated as Glas. in post-nominals) is a public research university in Glasgow, Scotland.
