At least that's the view of a team of physicists led by Jose Luis Aragon of the National Autonomous University of Mexico, who analysed several of VanGogh's later paintings, including Starry Night (see on the left), Road with Cypress and Starand Wheat Field with Crows. Mathematically, they studied how the luminosity, which is a measure of the total amount of visible light reflected off the paintings, varied across the canvas. Specifically, they analysed the likelihood that two points a distance D apart would have the same, or similar, brightness.
Almeno questo è il parere di un team di fisici guidato da Jose Luis Aragon dell'Università Nazionale Autonoma del Messico, che ha analizzato molti degli ultimi dipinti di VanGogh, tra cui la "Notte Stellata"(vedi a sinistra), la "Strada con cipressi e stelle" e il "Campo di grano con corvi".
