Actually the problem was omnipresent. But I can take one example, which is on page 23 the second last equation of the entire text. It says: -d²y/dt²=epsilon/m* v/c * N * sqrt(1- v²/c²) Now I wrote * for multiplication, while Einstein wrote no such signs. This will be interpreted as scalar multiplication. So we have a subpart '...vN...' in this equation. since v is a vector and N, too, we have a scalar product of two perpendicular vectors, what is zero. That would say, that acceleration in the y direction is zero (what is wrong). Actually the cross product had to be applied here, because the electron gets curved in the x,y plane, if the magnet is placed in the z direction. (To call the magnetic field from the z-direction 'N' was also an error.) TH
