Hi, I’m brazilian. There’s a teacher of Phisics in Brazil called Renato Brito. He’s a engineer of ITA. ITA is the aeronautical and aerospacial engineering college of Brazil. It’s something like ITT of yours. IT’s very hard to enter into ITA. Well the ITA engineers put EMBRAER planes on air. That guy today is a teacher of Physics. The most of ITA graduates in Brazil came from Renato Brito efforts like a teacher. He wrote two books on Mechanics and he loves MIR books as you too. Ask him to publish both of them in english ! A link for his books: http://www.vestseller.com.br/busca.asp?categoria_id=6
