Christiaan Huygens

The universe is a source of endless inspiration for scientists and philosophers alike.

I have always sought to contribute to the collective knowledge of mankind.

The legacy of scientific discovery is a gift to future generations.

The pursuit of truth is a journey that never ends.

It is not possible to explain the phenomena of light by any other hypothesis than that of waves.

Light is not a substance, but a motion propagated through the ether.

The wave theory of light explains reflection, refraction, and diffraction.

Every point of a wavefront may be considered as a source of secondary waves.

The propagation of light is analogous to the propagation of sound.

The true cause of the phenomena of nature is to be sought in the mechanical principles of motion.

It is by the help of geometry that we can arrive at the knowledge of the true causes of things.

The pendulum clock is the most accurate instrument for measuring time.

The cycloid is the tautochrone curve.

The center of oscillation is a point in a rigid body oscillating about a fixed axis, such that if all the mass of the body were concentrated at this point, the period of oscillation would be the same.

The force of gravity acts equally on all bodies, regardless of their size or composition.

The laws of motion are the same for all observers in uniform motion.

The rings of Saturn are composed of numerous small particles.

Titan is the largest moon of Saturn.

The true figure of the Earth is an oblate spheroid.

The principle of conservation of momentum is fundamental to mechanics.
