This title presents a synthesis of what has been discovered about particle acceleration and kinematics from solar flare observations with the Yohkoh, SoHO, TRACE, CGRO spacecraft and radio instruments over the last decade of the 20th century. It deals with the topology of magnetic reconnection regions, discusses the geometry, small-scale dynamics, and electromagnetic fields of acceleration region in solar flares, provides a systematic description of the relativistic kinematics of particle acceleration, propagation, time-of-flight measurements, particle trapping, precipitation, and the resulting emissions in gamma rays, hard X-rays, and radio wavelengths.
