It is mainly in French, but I believe this is not a problem for Marie-Hélène.

Regarding the feasibility of the cannon...
I've addressed this issue in a couple of articles. In short, I think that Verne was perfectly aware of the impracticality. To than end, he had a character voice all of the objections that would naturally occur to a 19th century reader...and have them answered by a character of authority. The entire episode of launching the animals was to create a sense of verisimilitude.
That he used a cannon instead of a rocket was, again, an attempt to create something his readers would believe. Given the state of the art of rocketry at the time he was writing, there is not a single reader who would have accepted the premise of a rocket large enough to reach the moon. On the plus side, Verne was perfectly aware of the fact that rockets would work in a vacuum...a fact that eluded even the New York Times in the early part of the 20th century when it criticized Goddard's experiments.

The calculations in Topsy Turvy would not work, apparently, but I recall that there was an appendix to try to explain why it did not work. Even then I am not sure about it because the mathematics is complex.
Coming in late to this thread. The Jacques Laskar article that Marie-Hélène links to is a review essay on this excellent book –
Badoureau, Albert. Le Titan moderne: Notes et observations remises à Jules Verne pour la rédaction de son roman Sans dessus dessous. Actes Sud, 2005.
I’m with MHH, Sans dessus dessous is also among my favorites by Verne.
