概要 | Daniel Bernoulli (1700-1782) unified hydrostatics and dynamic theory of fluids by publishing 'Hydrodynamica (1738),' in which there appears Bernoulli's Theorem. Almost half a century before this publication Edmond Halley (1656-1742) had read a series of unpublished papers at the Royal Society meetings and tried to account for physics behind bird flight in a modern sense for the first time in the history of sciences. Halley proposed a method to estimate the dynamic pressure by use of the idea of 'hydraulic head.' He extended this idea to estimate the wing-beat of the pigeon. Although he made a mistake in his computation, we validate his method by the corrected procedure. |
