Thomas Young's contributions to mechanics

Thomas Young was a polymath scholar, and his research interest coveredoptics, acoustics, hydrodynamics, medicine, strength of materials,archaeology, language, assurance, etc. However, his contributions tomechanics didn't draw a lot of attentions of his contemporary scientists dueto some reasons. These contributions include mechanics of materials,hydrodynamics of blood, energy, impact dynamics, surface wetting mechanics,structural analysis of engineering materials, etc. He was a pure naturalphilosopher, and at the same time he combined his theory with theengineering applications, with the spirit of engineering science beingrealized.
