||1641: Reinier de Graaf dies ... physician who discovered the follicles of the ovary (known as Graafian follicles), in which the individual egg cells are formed (1672) and also published on male reproductive organs (1668). He was also important for his studies on pancreatic juice (1663) and on the reproductive organs of mammals. He is considered one of the creators of experimental physiology. He used a technique of injecting dye into organs in order to be able to observe them better. It was on this technique that a bitter priority dispute with Swammerdam developed. He wrote a brief tract on the use of the syringe in anatomy (1669). He died, perhaps by suicide, at only 32 years of age. Pic.

||1978: Robert Edward "Rufus" Bowen dies.  He specialized in dynamical systems theory.

Pic.
 
||1978: Umberto Nobile dies ... aviator, aeronautical engineer and Arctic explorer. Nobile was a developer and promoter of semi-rigid airships during the period between the two World Wars. He is primarily remembered for designing and piloting the airship Norge, which may have been the first aircraft to reach the North Pole, and which was indisputably the first to fly across the polar ice cap from Europe to America.

||2010: Qian Weichang dies ... physicist and applied mathematician. He was generally acknowledged as one of the pioneers and founders of modern mechanics undertakings in China. His major research activities include; the intrinsic theory of plates and shells, the analysis of large deflection of thin plates and shells, the analysis of corrugated pipes, mechanics of armour penetration, singular perturbation methods, variational principles and generalized variational principles, finite element methods as well as the measurements of atmospheric electricity, spectral analysis of rare-earth elements, wave guide theory, lubrication theory, the development of high-energy batteries, his macro-coding of Chinese characters, etc. The joint work with J. L. Synge on the intrinsic theory of plates and shells is considered as a pioneering classical work in solid mechanics and his successive approximation method of treating large deflection problem is now named as "Chien's method". Pic.
