But the first man-carrying, rotary wing flight occurred in 1907, when Paul Cornu-yet another Frenchman-flew at a height of a few feet for a few seconds, and it was not until 1938 that the first fully controlled helicopter flights were carried out.

Rotations and e , ν Propagators , Part II Richard

We continue to derive spacetime quantities and spin 1/2 propagators from rotations. Rotation-invariant projection operators are found for each element of a four element basis, i.e. a basis for four component quantities with specific transformation rules under rotations. With these four projection operators, we make two spacetime invariant projection operators, i.e. once space, time, energy, and...
