Do you remember the movie Hidden Figures? It tells the true story of the first African-American female mathematicians who were decisive at NASA during the space race. The translated title of the book it was based on, Talentos ocultos, seems more accurate to me: it describes the brilliance and perseverance of those women in a socially brutal era for them. But what truly moved me was their passion for work. The light in their eyes. The hours they spent without realizing it. The absolute involvement in what they were doing.
