My entire life I have known speach to mean the verb that describes the act of speaking in the present tense, while speech to be the verb that is the past tense act of speaking professionally/publicly to a group.
According to google :The correct spelling is speech. “Speach” is an outdated spelling from hundreds of years ago and is now considered a spelling mistake.
Canonically speaking, I think Doc Brown just barely didn’t work with Einstein. He would have worked with Oppenheimer and crew though. He may have even met Einstein.
Where is the canon that explains that? Is there some BTTF official graphic novel or something?
There were some comics, and some cut bits of script and character backstory, that detailed him working for the Manhattan Project, among a lot of other cool bits of Emmet Brown backstory that are probably still around somewhere. A lot of the guys thought Doc Brown was a bit eccentric, because he studied everything he could, refusing to purely specialize.
I guess that explains why the original power source was plutonium.
Thanks for the info! I never knew there was a canon Emmet Brown back story.
