News: "Diffraction since Newton" 2008
Newton’s view of diffraction is described. Diffraction is differentiated in
light and shadowside diffraction and supplemented with references to addional
experiments.

contributions. Newton's diffraction experiments and their
continuation
Newton reported completely about the diffraction, also where he could not
explain the measuring results or explain mathematically. If today one checks the
diffraction experiments of Fresnel,thus one finds out that his information very
exactly is right. But exactly where his theory does not fulfil the measuring
results any more enough, exactly there he breaks off the communication of his
measuring results without pointing to the divergences.
Fresnel worked on, above all, the external diffraction stripes of the hindrances
which correspond to the diffraction in the halfplane. There the shadow borders
can be determined slightly geometrically, because from there the diffraction
stripes are measured out. In a limited area he could formulate the diffraction
figure of the halfplane and the external diffraction stripes of the slit in
very big distances with the help of the Fourier's theorem (Fresnel integrals)
mathematically, whatis a permanent merit for him .
In textbooks borderline cases are taken into consideration since 1850 only
Fresnels. Newton's diffration experiments are suppressed  this must be
corrected immediately.
historical and philosophical conclusions Historical conclusions
are analyzed which have originated from the nonobservance of the Newtonian
diffraction experiments. Further the philosophical arguments which are based on
the same cause are analyzed.
Heisenberg concluded for the structure of the photon the formal beginning: lying
side by side Fermion and Antifermion with Spin and Antispin. He looked at the
photon with structure and the Spin not as formal spinquantumnumber, but as a
spin rotation or clearly as a vortexaggregate .
