The answer was in my previous message: please do read it again for an answer
to your question.

Friends...

According to "Le livre de poche" of Hachette, we've got:

Le physicien et astronome Jules Janssen, le mathématicien Joseph Bertrand
refont les calculs de Jules Verne, et vérifient dit-on l'exactitude des
courbes, paraboles et hyperboles qui définissent le traject du boulet-wagon
de De la Terre à la Lune.

And this french web page we can read again:

Nous sommes en 1865, Jules Verne écrit alors un des plus beaux romans
d'anticipation de toute son histoire, passionnant de par son intrigue,
magnifique de par sa poésie, mais aussi -et surtout- des plus exacts, on dit
même que les courbes, les paraboles et hyperboles qui définissent le trajet
du boulet-wagon auraient été vérifiées avec exactitudes par le physicien et
astronome Jules Janssen, et par le mathématicien Joseph Bertrand. "De la
Terre à la Lune" est un roman de Science, pas de Science Fiction !

Then, with regard to "From the Earth to the Moon", I think (I'm sure)
Bertrand made the calculations of the novel, so till now I don't understand
why Henri Garcet is mentioned by some sources like FAQ for example....I hope
having your assistance to my question...thanks

Sincerely

Cristian Tello

Hi all forum members,

 

I'm working in some paper dealing with JV's Moon novels. So far, I have came
across different information regarding the person who help Jules with all
the mathematical job for his novels From the Earth to the Moon and Around
the Moon. Some sources mention it was Bertrand. On the other hand there are
another ones that mention Garcet as the collaborator. So my question is:
Which one was Verne's collaborator? Garcet or Bertrand or both?, though
according to me, I think it was Bertrand buy I don't want to have any
doubts. I'll be waiting for your answers...and I'm attaching some of my
sources:

 

 <http://jv.gilead.org.il/FAQ/index.en.html#C14>
http://jv.gilead.org.il/FAQ/index.en.html#C14 (Henri Garcet)

 

he received from two mathematicians: his cousin Henri Garcet and Albert
Badoureau. The first did all the mathematical calculations for From the
Earth to the Moon and the latter helped in the writing of Topsy turvy.

(Bertrand)

 

L'intérêt de Jules Verne pour les sciences ne s'arrête pas là, comme le
montrent les nombreux contacts qu'il a eus avec des savants de tous
horizons: l'académicien Joseph Bertrand (spécialiste en balistique, dont les
calculs serviront à De la Terre à la Lune)

http://fr.ca.encarta.msn.com/encyclopedia_761576584/Verne_Jules.html
(Bertrand)

 

qui compte notamment des scientifiques, tels le physicien et astronome Jules
Janssen et le mathématicien Joseph Bertrand, qui recalculent l’exactitude
des courbes, paraboles et hyperboles qui définissent le trajet du
boulet-wagon de De la Terre à la Lune.

 

Can anybody give me some light on this matter?

 

Best regards, Cristian Tello
