25K views · 322 reactions | Should we rename an SI unit after Emmy Noether? The unit of momentum is currently known as kilogram metres per second (kg m/s) according to the International System of Units. However, in a letter to the American Journal of Physics a teacher has started a campaign for it to become know as the noether. Emmy Noether was a mathematician who changed physics with her discovery that symmetries are at the heart of physical laws. | Nature | Facebook

2.3K views · 39 reactions | #BackToSchool The shifts system has been introduced in the school curricular this year to limit the number of students per class and bar the way to COVID-19. This system according to some parents is difficult to cope with due to their work schedules. In the following interview, Romual TEDJO, an orientation counselor at Government High School Anguissa says parents and students can adapt to the new system by drawing a timetable. | CRTVweb | Facebook
