Campinas
I lived in Campinas during my undergraduate studies at Unicamp. Campinas it's one of the biggest Brazilian cities. The metropolitan area of Campinas is the center of a huge metropolitan region with four million inhabitants, consisting by 19 cities and encompassing one of the major Brazilian technological poles. The region is known as the "Brazilian Silicon Valley", because of its research centers and universities such as and University of Campinas and Embrapa. Campinas means grass fields in Portuguese and refers to its characteristic landscape, which originally comprised large stretches of dense subtropical forests, thick woods mainly along the many rivers, interspersed with gently rolling hills covered by low-lying vegetation.
