We analyze the constraints of general coordinate invariance for quantum theories possessing conformal symmetry in four dimensions. The character of these constraints simplifies enormously on the Einstein universe R× S. The SO(4, 2) global conformal symmetry algebra of this space determines uniquely a finite shift in the Hamiltonian constraint from its classical value. In other words, the global...

Emil Theodor Kocher--valve surgery for epilepsy.

Emil Theodor Kocher (1841-1917) was a pioneering and versatile Swiss surgeon who played a decisive role in the surgical evolution on the threshold to the 20th century. Apart from conducting intense research and fostering the development of the surgical treatment of thyroid gland diseases (honored with a Nobel Prize in 1909), he remained a generalist and was active in orthopedic, genitourinary, ...
