Scientific organization

Every day there will be about 4 hours of lectures in the morning, 3 hours of hands-on activities under the guidance of the lecturers in the late afternoon, and one after-dinner session for students to present their own work. The lectures will be given in Portuguese and Spanish. All the written material(presentations, exercises, documents) will be in English. A triligual (Portuguese, Spanish, English) compendium of the most usual words, especially for the topics of the school, will be given to each participant on the first day. Students must be prepared to have an active participation in the school. Each student is expected to come with a laptop with a text editor, Fortran and C++ compilers and Python installed. During the after-dinner sessions, students will have the opportunity to present their works and discuss them with the other students.
