:It looks rather obvious that the person who wrote the list of alleged Einstein's errors interprets terms not in the same way as contemporary physicists would. Whoever set the list should consult it with a physicist freshly from school since many terms in common language don't need to have the same meaninig in physics as they had in Einstein's times. E.g. word ''"mass"'' denoted now by ''m'', itself changed its meaning between Einstein's and contemporary times. It is presently the ''invariant mas'' while before, e.g. in ''"Feynman lectures on physics"'' <math>m</math> was strictly ''relativistic mass'' while ''"invariant mass"'' had to be denoted <math>m_o</math> which still causes endless arguments between physicists and engineers or chemists who each might use different conventions. It looks silly when alleged Einstein's error turns out to be due only to misunderstanding of a physical term. In Einstein's times photons, as today, had mass <math>m=h\nu/c^2</math> and only their <math>m_o=0</math>, which today is written <math>m=0</math> but only because '''idea''' of "mass" chaged, not its physics.
