Never liked Einstein. Arrogant a$$hole.
After Oliver Heaviside corrected Maxwell’s equations due to incorrect assumptions on the part of Maxwell, Einstein refused to credit Heaviside for this work and insisted on calling them Maxwell’s Equations, because Heaviside never went to college and did not have a degree from a university. Heaviside was poor and could not afford to go to college and was self taught. Thus, no degree, so no credit for brilliant work. Einstein would rather give the credit to the idiot who got it wrong.
Dropped the quaternions math for vectors. Resulted in a simplified subset of Maxwell’s work suitable for engineering, rather than a specialized physics.

Heaviside was a great and genuinely underappreciated scientist, but calling James Clerk Maxwell an idiot pretty much disqualifies any opinion you have from serious consideration.
