I've heard this repeatedly over the years, that Einstein was bad at math, that he was bad at history, that he was dyslexic. I also read somewhere in my youth that some of the " bad at math" stuff was based on a poor exam score he once received - but that the test had been in French, which Einstein couldn't read.
Can someone cut through the junk and get to the heart of this. Was one of history's greatest "teachers" a bad student, or have a learning disability? I find it hard to believe.
