If you're taking things like that back in time, make sure to translate them to French. Also, learn French. Not knowing French in the 17th century is like not knowing English today.
Also, learn French in Canada, not France prior to your trip back in time. I've been told that Canadians speak French like someone from the 1600s, and those visitors (in 2015) from France find it archaic to the ear.
Did Newton speak French? I'd guess not (or not very well). His principal scientific works were written in Latin, which was the academic lingua franca of the day.
I'm learning French. But where is the time machine?
