Rushton, E., Drysdale, R., Abmayr, S., Michelson, A., and Bate, M. (1995). Mutations in a novel gene, myoblast city, provide evidence in support of the founder cell hypothesis for Drosophila muscle development. Development 727 1979-1988. 

Problem 1. The first problem is only a warm-up-question dealing with Alfred Werner, the founder of coordination chemistry. His name is strongly linked to the definition of a complex because he discovered a hypothesis based on the spatial octahedral structure of cobalt complexes in 1892. Through synthesis of these complexes the hypothesis could be confirmed later. 

Democritus of Abdera (ca. 460 B.C. - ca. 370 B.C.), Greek philosopher, founder of the first atomic theory. According to him, nature represents a constant motion of indivisible and permanent particles (atoms), whose interactions result in various materials. It turned out after almost 25 centuries that this hypothesis was basically correct All the written works of Democritus have been lost, but his... 

The no-slip boundary condition is introduced in every text on fluid mechanics as a fundamental principle of the disciphne, and students are expected to accept the condition as obvious. No-slip is not obvious, however, nor was it obvious to the founders of the disciphne of fluid mechanics in the nineteenth century. Navier, in 1823, believed that there should be a relative ( slip ) velocity between the fluid and the solid surface that would be proportional to the shear stress at the wall in modern terminology we would write Navier s hypothesis as (cf. Equation 2.30)...
