# Did Daniel Bernoulli state van der Waals equation?

I read in some places that Daniel Bernoulli anticipated van der Waals equation by a century in section 10 of his Hydrodynamica. Most sources state that he only discovered one idea in the model; that of taking into account the size of the particles. But did he also consider the attraction between the particles? I'm unable to read his Latin work so I need someone to answer.

• Please explain in more detail what "van der Waals equation" you have in mind. It would help if you mention where you came across the claim. – vonbrand Feb 7 '16 at 1:53
• See I.Grattan-Guinness (ed) Landmark writings in western mathematics (2005), Ch.9 D.BERNOULLI, HYDRODYNAMICA (1738) by G.K.Mikhailov, page 138: "B proposes a kinetic model of air, consisting of a number of very small (but finite) spherical particles moving in straight lines at very high velocities.Taking into account the finite size of the air particles,B obtains also a generalization of the Boyle–Mariotte law in the spirit of the Van der Waals equation. Unfortunately, B’s kinetic theory was disregarded over more than a century." – Mauro ALLEGRANZA Feb 7 '16 at 8:47
• Thanks, but i've already read this source. Many sources claim that he took acount of the finite size of the particles, but i ask if he also thought about the \left(p + \frac{n^2 a}{V^2}\right) term of the equation. For this i need someone who is able to read the original latin of the work "Hydrodynamica". – user2554 Feb 7 '16 at 9:03
