  There will be a review of the history of polarized proton beams, and a
discussion of the unexpected and still unexplained large transverse spin
effects found in several high energy proton-proton spin experiments at the ZGS,
AGS, Fermilab and RHIC. Next there will be a discussion of possible future
experiments on the violent collisions elastic collisions of polarized protons
at the 70 GeV U-70 accelerator at IHEP-Protvino in Russia and the new high
intensity 50 GeV J-PARC at Tokai in Japan.
