Dutch mathematician Christiaan Huygens first states his wave theory of light, published in Traite de la lumiere in 1690. 

For example, by retaining only one term which differs from x we derive from (2.27) > (x) = x + xy xi. The solution of this equation represents the different planar planted trees with n nodes which have only vertices of degrees 1 and 3. Cayley already established this result, 2. Cf. F. Levi, Christiaan Huygens, 2 (1922), pp. 307-314, No. 5, further A. Errera, Mdimoires de I Acad mie royale de Belgique 11, 1931, pp. 1-26, No. 15-16. Both contain (2.28) in different form and investigations of planar free trees.

In the European scientific community, many scientists believed that light, like sound, traveled in waves. This group of scientists was most successfully represented by the Dutch physicist Christiaan Huygens, who challenged...

This final thrust, which centred around Isaac Newton, turned into an unseemly squabble with his contemporaries Robert Hooke (1635 - 1703), Edmond Halley (1656 - 1742), Wilhelm Leibniz (1646 - 1716), Christiaan Huygens (1629 - 95), Robert Boyle (1627 91), Christopher Wren (1632... 

Huygens construction (Huygens principle) Every point on a wavefront may itself be regarded as a source of secondary waves. Thus, If the position of a wavefront at any instant is known, a simple constmction enables its position to be drawn at any subsequent time. The constmction was first used by Christiaan Huygens.

Swiss mathematician Daniel Bernoulli introduced the term hydrodynamics with the publication of his book Hydrodynamica in 1738. The name referred to water in motion and gave the field of fluid dynamics its first name, but it was not the first time water in action had been noted and studied. Leonardo da Vinci made observations of water flows in a river and was the one who realized that water was an incompressible flow and that for an incompressible flow, V = constant. This law of continuity states that fluid flow in a pipe is constant. In the late 1600 s, French physicist Edme Mariotte and Dutch mathematician Christiaan Huygens contributed the velocity-squared law to the science of fluid dynamics. They did not work together but they both reached the conclusion that resistance is not proportional to velocity it is instead the square of the velocity. 

Sir Isaac Newton was one of the most frimous scientists to put forward the particle theory of light. Dutch scientist Christiaan Huygens was a contemporary of Newton s who advocated the wave theory of light. This debate between wave theory and particle theory continued into the nineteenth century. Trench physicist Augustinjean Eresnel was influential in the acceptance of the wave theory through his experiments in interference and diffraction. 

Pendulum clock (Christiaan Huygens) Huygens discovers that, for small oscillations, a pendulum s period is independent of the size of the pendulum s swing, so it can be used to regulate the speed of a clock.
